Cycloidal hydraulic motor structure: the internal meshing gear pair consisting of rotor and stator, cycloidal needle wheel, as the meshing pair, has a torque generating part. The stator, together with the spacer and the rear cover, is fixed on the housing to form seven cavities that are only connected with the oil holes on the housing one by one. A distribution mechanism consisting of an oil distribution sleeve and a housing. Two oil distribution sleeves Cangzhou Low speed cycloidal hydraulic motor The ring groove is respectively connected with the oil inlet and return ports of the housing, and its longitudinal groove has twelve oil ports, Low speed cycloidal hydraulic motor Price Six oil ports and the oil distribution hole of the housing form the oil distribution link. The splines at both ends of the linkage shaft are respectively connected with the rotor and the output shaft, which is used to transmit torque and ensure that the oil sleeve is synchronized with the output shaft. The function of the output shaft is to output the torque generated by the rotor through the linkage shaft and drive the oil distribution device to rotate synchronously.

In the late 1850s, the original low-speed high torque hydraulic motor was developed from the fixed rotor part of the oil pump, which consists of an internal gear ring and matching teeth Cangzhou Price Wheel or rotor. The inner gear ring is fixedly connected with the housing, and the oil entering from the oil port pushes the rotor to rotate around the center point. This slowly rotating rotor is driven and output by a spline shaft to become a cycloidal hydraulic motor. After the first cycloid motor came out, after decades of evolution, Jinjia hydraulic hydraulic motor delivers high efficiency energy for you. Another concept of motor also began to form. The motor installs the drum in the built-in ring gear. Motors with rollers can provide high starting Low speed cycloidal hydraulic motor Price With the running torque, the drum reduces friction and improves efficiency. The low speed output shaft can also produce stable output.

Its basic types are gear type, screw type, vane type and axial plunger type. Its main characteristics are high speed, small moment of inertia, convenient starting and braking, adjustment (speed adjustment and customized Low speed cycloidal hydraulic motor Reversing) High sensitivity. As the output torque of high-speed hydraulic motor is generally small, it is also called high-speed small torque hydraulic motor. Its basic type is radial plunger type, in addition, there are axial plunger, vane type, gear type and other structural types. Low speed hydraulic motors are mainly characterized by large displacement, large volume and low speed (sometimes Low speed cycloidal hydraulic motor Price It can rotate a few revolutions per minute or even a few revolutions per minute), so it can be directly connected to the working mechanism; It does not need a speed reducer, greatly simplifying the transmission mechanism. Usually, the output torque of low-speed hydraulic motor is large, so it is also called low-speed high torque hydraulic motor.

The oil distribution sleeve is synchronized with the rotor, so that the rotor rotates once, and the seven oil distribution holes on the housing are closed 840 times by the twelve diaphragms of the oil distribution sleeve, while the rotor and stator form the largest and smallest closed cavities respectively 1420 times, collectively referred to as the seal cavity. In the circle of the oil distribution hole of the closed housing, the oil inlet and outlet of the rotor have three chambers respectively, one Cangzhou Low speed cycloidal hydraulic motor The cavity is closed. When the rotor is transferred from the smallest enclosed cavity to the next largest enclosed cavity, before the rotor is transferred from the largest enclosed cavity to the next smallest enclosed cavity, oil is supplied to four cavities and three cavities customized Low speed cycloidal hydraulic motor Drain the oil.

(1) Oil leakage at the shaft end: because the oil seal and output shaft are under constant friction during the use of the hydraulic motor, the wear of the contact surface between the oil seal and the shaft will be caused Cangzhou Low speed cycloidal hydraulic motor A certain limit will make the oil seal lose its sealing effect, and oil will leak. Our solution is very simple: replace the oil seal. If the output shaft is seriously worn, it must be replaced. (2) Crevice oil leakage: the "O" ring between the motor housing and the front side plate, or between the front side plate and the stator body, is aged Low speed cycloidal hydraulic motor Price Just replace the "O" ring. (3) Oil leakage at the cover: the "O" ring under the cover is aged and loses its sealing effect. The probability of this situation is very low, even if it happens, just replace the "O" ring.

As a kind of hydraulic transmission device, hydraulic motor has been widely used in many places. In fact, I have seen it on many occasions. The main application fields are. 1. The hydraulic motor has convenient speed regulation, which can be adjusted infinitely from 0 to the maximum speed according to the adjustment of the hydraulic valve. The motor itself does not need special design and has low cost. This is much cheaper than motor+reducer, or variable frequency motor and servo motor. 2. The hydraulic system has strong anti overload capacity and relies on the overflow valve for protection, allowing a long time customized Low speed cycloidal hydraulic motor (Relatively) Frequent overload, easy to recover under overload, no damage to equipment, no restart of equipment. 3. The hydraulic system is characterized by high energy density. For motors of the same power, hydraulic motors are much smaller than motors Low speed cycloidal hydraulic motor Price , much lighter. And it is easy to apply to mobile devices. 4. The hydraulic motor is totally enclosed and can be safely used in dusty, wet (even underwater) and flammable environments, which is much more reliable than explosion-proof (flameproof) motors.
