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 BM cycloid 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 BM cycloid motor Manufacturer 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.

Functions: It is used for the storage, supply and recovery of hydraulic media, the connection between hydraulic components and the transmission of energy carrying hydraulic media, filtering impurities in the hydraulic media, keeping the media required for the normal operation of the system clean, heating or cooling the system, storing and releasing hydraulic energy or absorbing hydraulic pulsation and impact, and displaying the pressure and oil temperature of the system; Hydraulic working medium: various hydraulic oils (fluids), efficacy: as the energy carrying medium of the system, it plays the role of lubrication and cooling while transferring energy. Generally speaking, the hydraulic components that can complete certain specific functions are called hydraulic circuits. In order to meet the working requirements of certain machinery or equipment, the overall structure of several special basic functional circuits connected or combined together is called hydraulic system.

After disassembling and inspecting the hydraulic motor installed on the drill, it was found that the friction surface of the valve disc and the port plate of the hydraulic motor was severely worn, and the deepest worn part was 0. 15mm; The output shaft oil seal is leaking. Cause analysis of oil leakage of output shaft oil seal. After disassembly inspection and test, the axial and radial clearances of the output shaft meet the standard requirements customized BM cycloid motor There is no obvious wear on the oil seal mating surface. However, it is found that the oil seal rubber has hardened and its elasticity has deteriorated. With the increase of sealing lip wear, the pre tightening capacity and sealing performance decrease, and the excessive oil temperature accelerates the wear of sealing lip; In addition, due to the liquid Zhaoqing BM cycloid motor The leakage of the pressure motor causes the back pressure in the housing to be too high, which further aggravates the wear and leakage of the sealing lip. The smaller the friction of the rotor in the stator sleeve, the higher the mechanical efficiency of the motor.

Cycloidal hydraulic motor, as a kind of construction machinery equipment with small price increase and light weight, is also widely used in daily life. Cycloidal hydraulic motor is a kind of motor, which is essential for some equipment. In fact, the operation of all hydraulic systems is almost the same. This cycloidal hydraulic motor is widely used Zhaoqing customized It is used in construction, manufacturing, mining and other industries, so pay attention to daily maintenance when using the motor to ensure the service life of the cycloidal hydraulic motor. In order to keep the whole system in a stable state, it is necessary to ensure that the motor function has a constant pressure, ensure that the hydraulic system is normal, and ensure that the pressure in the system is not BM cycloid motor Manufacturer leak.

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 Zhaoqing BM cycloid 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, BM cycloid motor Manufacturer 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.

Actuator: hydraulic cylinder, hydraulic motor and swing hydraulic motor. Function: convert the pressure energy of liquid into mechanical energy, which is used to drive the working mechanism to do work and realize reciprocating straight customized BM cycloid motor Linear motion, continuous rotation or swing; Governor: pressure, flow, direction control valve and other control elements. Function: control the oil pressure, flow and direction from the pump to the actuator in the hydraulic system, so as to control the force (torque) and speed output by the actuator Zhaoqing BM cycloid motor Degree (speed) and direction, to ensure that the main engine working mechanism driven by the actuator can complete the predetermined motion law; Hydraulic auxiliary device: oil tank, pipe fittings, filter, heat exchanger, accumulator, indicating instrument, etc.
