To overcome these limitations, engineers at Eco Green Equipment, a tire recycling equipment manufacturer in North Salt Lake, Utah, developed the Krumbuster. The Krumbuster’s output is 50% higher than the closest traditional cracker mill when making 30 to 60 mesh crumb rubber, according to Eco Green. These may be labelled 12:1 or 13:1 (or lower). Since there is no friction between the ring and the connecting rod shoes, hydrostatic balancing is not necessary. Shown is a modular cam-lobe motor, with rotating shaft output. The term slow speed high torque motor is not strictly defined, but it is restricted to a rotation speed range not exceeding 1 to 150—250 rpm (although this does not mean that controlled "high speed motors" cannot operate in this range too). Low speed high torque hydraulic motors remove the need for gearboxes, being an efficient and reliable component of a hydraulic system. View Contact Details. The cylinders work slightly out of phase so that no dead spots are created at top dead center. Low-speed/high-torque hydraulic motors eliminate gearboxes - reducing maintenance, meeting space constraints, and lowering costs. The ring follows the turning crank without rotating itself. Fixed side guides absorb reaction forces on the rollers, "unloading" the pistons from any tangential forces. The rolling vanes function as timing valves, sequencing the fluid flow to ensure high pressure against trailing surfaces and low pressure against leading surfaces. A 6-lobe/7-lobe gear set has a 6:1 mechanical advantage. With the same setup, it can also produce up to 2,000 lb per hour of 30 mesh rubber powder. Torque is defined as the cross product of the force vector and distance vector to axis of rotation. Each tooth of the rotor is in sliding contact with the outer ring at all times. The 3Z Motor series has high flow and low pressure drop across a wide speed range. Vane motor is hydraulically balanced because pressurized fluid always acts on equal and opposite areas. Each of three Char-Lynn Geroler product lines include a wide variety of available displacements customizable specifically for application needs. Fluid entering the housing forces the gears to rotate, and exits through the opposite side of the motor. Vane motors resemble traditional hydraulic vane motors, Figure 1, where vanes ride a ring cam and slide in and out of rotor slots. Low noise and vibration and high energy efficiency can be additional benefits. In addition, a three-section Parker T6 vane pump generates up to 250 psi to supply make-up oil to the other pumps and motors in the closed system. } Parker T6 three-section vane pump boosts flow to the main pumps and provides oil flow through the heat exchanger and filters. Because operating clearances around the balls are small, volumetric efficiency is often very good. You entered 'Search'. These motors generally exhibit good starting efficiencies and fairly constant torque over their entire speed range. In the recycling process, a cracker mill turns the rubber in recycled tires from which steel and tire cord are removed into smaller “crumbs.” In the mill, two corrugated rolls operating at different speeds crush and grind the rubber into particles. Low-speed/high-torque (LSHT) motors are one of the more cost-effective and dependable parts of a hydraulic system. There are many variations among basic LSHT motor designs. Radial-piston motors have a great variety of designs within the basic radial configuration. height: 202px; All three pumps are assembled and connected at the same time. high torque motor with hollow shaft for 24V dc, 48V dc, 230V ac, 400V ac, high pole count servo motor, rotary direct drive motor, rotary motor table with bearing and feedback (incremental or absolute encoder) and hollow shaft, low cogging torque, high torque kit motor Using bearings centered around the barrel instead of a support shaft reduces the size of the Gold Cup axial piston pump and provides higher speeds and saves energy.Parker Hannifin. The high torque power of these motors is necessary to move the weight of objects like elevator doors, automated safety and security gates, emergency barriers, cargo lifts, freight systems, garage doors, … 1. Low-Speed, High-Torque (LSHT) Motors - Geroler, #textArea .wt-rotator .main-img { Ahmedabad, India ... More C-67, Maruti Est, Naroda Road,Ahmedabad, Gujarat, India . Hydraulic power lets it respond quickly to changes in friction ratios, high shock loads and constantly changing pressures, including pressure spikes. At the same time, other cylinders allow oil to escape through their valves to the tank drain port. This style of motor has a high starting torque and is very efficient in the medium- to high-displacement range. Low Speed High Torque Motors; Expand Filters. Rapid reversal of direction may be achieved simply by reversing the direction of hydraulic fluid flow. Rolling-vane motors have fluid flow through the motor body to the rotor shaft through a combined body-and-shaft groove. Common Applications Of High Torque Low RPM Motors Low-speed electric motors are frequently used in systems and machinery that must lift considerable weight in a smooth, controlled, and safe manner. The vanes form sealed chambers, which carry fluid from an inlet to an outlet. These vanes ride a ring cam and slide in and out of rotor slots. A torque motor is a specialized form of DC electric motor which can operate indefinitely while stalled, without incurring damage.In this mode of operation, the motor will apply a steady torque to the load (hence the name). Finally, axial-ball-piston motors have multiple wave cams that are pressure balanced to operate without vibration or pulsation. The Krumbuster cracker mill uses hydraulic power to recycle tires into quality crumb rubber used to make pavement, playground surfaces and even artificial turf.Eco Green Equipment. High Torque Low Speed Hydraulic Motor. Torque motor and High Torque motor A torque motor is an electrical motor that is used for applications at low rotary speed quite often in direct drive without gear. External-gear motors consist of one gear connected to an output shaft, and a matched idling gear. When the motor is fully running, the gears are retracting faster and can pull a low power spring back faster. The Gerotor set has a stationary outer ring which is part of the motor housing, and a rotor. The outer ring has integral gear teeth which mesh with mating teeth on the rotor. Page .

As the speed increases, the torque decreases. The pumps also allow nearly infinite adjustment of the friction ratios so the rolls can be calibrated to suit the material being processed and the desired particle output size. Foremost is the fact that LSHT motors transmit a large amount of power from a comparatively small drive envelope. Ray I. Scroggins is a contributing editor. Fig. Low-Speed, High-Torque (LSHT) Motors - Geroler Eaton is proud to be recognized as an industry leader in Low-Speed, High-Torque (LSHT) hydraulic motor technology. As system pressure increases, pressurized fluid trapped in the connecting rod pocket increases, automatically compensating for increased piston loading and keeping the percentage of mechanical loading constant at a low level. The performance of a torque motor over its velocity range is illustrated in its torque/speed curve. Displacements of up to 650 in.3/rev are available. Fig. The two piston pumps have bearings centered around the barrel instead of conventional roller bearings supporting a large diameter shaft. 66. There are no side loads. Low speed may bring about torque ripple or speed flutter. The Krumbuster cracker mill uses hydraulic power to recycle tires into quality crumb rubber used to make pavement, playground surfaces and even artificial turf. A torque of up to 4,750 Nm at the main spindle and rotational speeds of up to 12,000 rpm or, optionally, 8,000 and 18,000 rpm at the high speed turning/milling spindles ensure an … They provide constant torque at all friction ratios and can be started under load, so the rolls don’t have to be cleaned out before starting the machine. Packaging, Security System. Our premium line of Char-Lynn® motors and standard line of Xcel motors both feature a design based on the Orbit Principle in which an internal gear rotates inside of an external fixed gear. Min. Das Drehmomentspektrum beginnt bei 325 Nm und reicht bis zu einem Spitzend… LSHT vane motors run most efficiently at lower pressures and are radially balanced, which extends their operating life. The lower speed motor relies on a P6 Gold Cup pump with a maximum displacement of 6.00 in3/rev. Hydraulic Pump/Motor Div. Foremost is the fact that LSHT motors transmit a large amount of power from a comparatively small drive envelope. The rollers provide support and rolling contact to minimize friction as the inner gear rotates.These motors generally are referred to as geroller motors. Send Inquiry . Instead, here are some important points about four of the main LSHT motor styles: Vane motors - These motors, Figure 1, resemble traditional hydraulic vane motors, in which pressure (assisted by springs) pushes against a series of vanes. The radially mounted pistons in motors of another design reciprocate inside bores in a stationary cylinder housing and are connected to rollers that bear on a cam ring. High Speed Low Torque Gear Motor. Eco Green says the pumps were chosen for their reliability, responsiveness and the ability to handle the high shock loads the process creates. 3. The commutator valve, connected to and rotating with the output shaft, routes pressurized fluid to the spaces between the gear teeth. While regulatory requirements that were recently instituted impact the design of machines, your customers are constantly looking for more efficient, economical and user friendly machines.

Crumb rubber and rubber powder made from recycled tires are in growing demand for use in artificial turf, playground surfaces, pavement and other applications. Current cracker mills have a fixed or narrow range of these speed differentials, known as friction ratios, and this limits their ability to turn out enough of the material with the right level of quality and size. Featuring hydrodynamic journal bearings optimized for long life, Eaton Spool valve motors distribute pressurized fluid into the Gerotor or Geroler® orbit gear set for smooth performance over a longer period of time. The rotor has one less tooth than the outer ring. Low ratio gears (labelled as high-speed gears or gears with a low number) decrease the number of turns your motor needs to make for a full revolution of the gearbox. On both of these types, the manufacturers speed recommendations must be followed closely. The unit of maximum torque speed is RPM, which means the maximum torque of the engine occurs at this speed. The Torqmotor™ TF Clutch Series low speed, high torque motor is ideal for applications where a freewheeling output shaft is required for some part of the duty cycle. The hydraulic load on the piston crown is transmitted to the connecting rod through a passage to a pressure-compensated hydrostatic bearing. per page. Motors known as cam-type radial-piston motors, Figure 2, are slightly less efficient because of their concentric configuration. This creates a high-pressure column of oil which is trapped in a relieved area of the connecting rod foot. The following are representative: Gear motors usually are of Gerotor design and consist of a Gerotor set, a splined drive coupling, and a commutator valve. This replaces oil lost through designed-in leaks that lubricate the component’s hydrostatic bearing surface, as well as providing oil flow through the heat exchanger. They are radially balanced, as pressurized fluid always acts on equal and opposite areas. In cement mill, high torque at low speed (3 RPM) is normally obtained using (a) Compound DC motors (b) VFD Induction Motor with gear arrangement. Eaton is proud to be recognized as an industry leader in Low-Speed, High-Torque (LSHT) hydraulic motor technology. It’s a hydraulically powered cracker mill designed to crank out up to 4,000 lb of crumb rubber per hour in sizes smaller than 6 mesh. Select attributes to refine your product search. These motors have a somewhat limited displacement range and, like vane motors, cannot tolerate cavitation.

The motor is bidirectional, depending on which port is pressurized. Fig. Good starting torque characteristics are also inherent to this design. Models for heavy-duty applications, and those which require higher shaft load capacities, use precision-machined rollers to form the displacement chambers. Meaningless turns to fire a shot. Checkbox. Die getriebelose Antriebstechnik bietet als Alternative sowohl zur Motor-Getriebe-Kombination als auch zu hydraulischen Systemen erhebliche Vorteile. Maximum shaft speed for LSHT motors can range up to 1,000 rpm, and some motors operate smoothly at speeds as low as 0.1 rpm with suitable closed-loop electronic control. Low Speed High Torque - (50) Component Style. All rights reserved. Traditional cracker mills have a separate mechanical gearbox and motor driving each roll; their friction ratios are fixed by the gearboxes. Pressure and return passages in the commutator valve are connected to the motor ports through the housing.

They are similar to a cam design in this regard. Because the pressurized fluid always acts on equal and opposite areas, the rotors are always in hydraulic balance. Eaton Xcel motors offer a 3-zone protection at a 2-zone motor’s price point, with less wasted energy and lower operating temperatures. A third design also produces thrust on an eccentric crankshaft through connecting rods, a heat-treated ring, and spherical roller bearing. width: 546px; Direct drive torque motors deliver high torque over a wide range of speed, from a stalled or low speed condition to high angular velocities. Piston motors - There are several different designs that fall under this category. Internal-gear motors have an inner and outer gear set within the housing, with the inner gear having fewer teeth. LSHT motors also exhibit smooth starting torque. In the higher speed range, the torque is halved. Please enter another search term. Eaton HP and VIS motors are small but powerful solutions for closed-loop applications that provide higher pressure capability and better efficiency than other types of Low-Speed, High-Torque (LSHT) hydraulic motors. These motors use pistons in several cylinders to push down on an off-center throw of a crankshaft drum. OF TIGHTENING TIGHTENING MOTOR BOLT PART NO. Passages within the rotor shaft route high-pressurized fluid radially into pressure chambers; symmetrical passages route low-pressurized fluid back through the rotor shaft and body to the outlet port.
