Axial plunger type roller line Oil motor The bearing holes of the stator (oil distribution shaft) and rotor (cylinder body) of the stator (oil distribution shaft) and the rotor (cylinder body) belong to high-precision mating parts. When the stator (oil distribution shaft) suffers from the effect of axial unbalanced hydraulic working pressure, it is easy to wear with the cylinder (rotor) hole. The gap after wear cannot be compensated, and the leakage is large, The rotary drum line oil motor will be damaged after long-term application or improper application. There are two ways to repair it. Let's have a look.

1. Axial plunger type Cycloid hydraulic motor The bearing holes of the stator (oil distribution shaft) and rotor (cylinder body) belong to high-precision mating parts. When the stator (oil distribution shaft) suffers from the effect of axial unbalanced hydraulic working pressure, it is easy to wear with the cylinder (rotor) hole. The gap after wear cannot be compensated, and the leakage is large. Cycloidal hydraulic motor of snow sweeper The basic principle of reproduction repair is to repair the original clearance between the rotor and stator. Under the standard of not endangering the bending stiffness of the cylinder body, the cylinder body shall be bored and processed according to the wear condition, and the stator (oil distribution shaft) shall be plated with hard chrome and machined to repair the original characteristics of the parts and the clearance between them.

2. The repair of the inner bevel stator and plunger comes from the high pressure oil of the hydraulic oil pump, which is distributed to the axial piston rod on the cylinder (rotor) through the oil inlet of the stator oil distribution shaft. The other end of the piston rod is connected to the roller, and the roller clings to the inner bevel stator with axial force travel arrangement by means of back pressure. The piston rod is at the bottom dead center. When the roller is in contact with the high point of the inner inclined plane of the stator, the piston rod is at the bottom dead center, and the hydraulic oil pressed back flows to the car oil tank through the return inlet port on the oil distribution shaft. According to the driving torque caused by the repeated movement of each piston rod in the cylinder body (rotor) hole, the cylinder body (rotor) is driven to rotate and transmitted from the main shaft bearing. If the plunger and rotor holes are severely worn, the pulsating drinks of the motor's torque and speed ratio will be harmed. If the roller component in front of the plunger and the sliding rail of the stator's inner slope are severely worn, It can also lead to working pressure, pulsating drinks and shock conditions.
