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 High speed high torque cycloidal hydraulic 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 Jilin High speed high torque cycloidal hydraulic 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.

The radial piston hydraulic motor uses a cam ring with a special curve to make each plunger reciprocate several times within one cycle of cylinder block rotation, which is called multi action customized High speed high torque cycloidal hydraulic motor Internal curve radial plunger hydraulic motor (referred to as internal curve motor) is used. The internal curve motor has the advantages of small size, light weight, radial force balance, small torque ripple, high starting efficiency, stable operation at very low speed, etc. It has been widely used High speed high torque cycloidal hydraulic motor Price In marine machinery. Working principle of inner curve motor: the inner wall of the cam ring (housing) is composed of x evenly distributed curved surfaces with the same shape. Each curved surface with the same shape can be divided into two symmetrical sides. The side that allows the plunger set to extend outward is the working section (oil inlet section), and the opposite side is called the oil return section. The number of reciprocating times of each plunger per revolution of the hydraulic motor is equal to the number of curved surfaces of the cam ring x (x is called the number of times of action 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 Jilin 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 High speed high torque cycloidal hydraulic motor Price leak.

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 Jilin 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 High speed high torque 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.

Most of its hydraulic system uses working medium, such as hydraulic oil with continuous fluidity, which converts the mechanical energy of the prime mover driving the pump into the pressure energy of the liquid through the hydraulic pump, and sends it to the actuator (hydraulic cylinder, hydraulic motor or swing hydraulic motor) through various control valves, such as pressure, flow, direction, etc., to convert it into mechanical energy to drive the load. This hydraulic system is generally composed of the following parts: power source, actuator, control valve, hydraulic auxiliary device and hydraulic working medium, which play their respective roles: power source: prime mover (motor or internal combustion engine) and hydraulic pump, whose role is to convert the mechanical energy generated by the prime mover into the pressure energy of liquid, and output oil with a certain pressure;
