(1) Insufficient output torque

① The internal hole of the roller and the housing hole are too loosely matched, or the working pressure oil in the oil inlet chamber leaks back to the oil chamber (oil outlet chamber) after the application is damaged, and the internal leakage is expanded. At this time, the roller should be added according to the brush plating or re production and processing.

② The blade root circle of the motor rotor is damaged with large internal leakage.

③ The blade and roller are stuck by waste.

④ Due to poor machining precision and installation precision between roller and blade shaft, Cycloidal hydraulic motor of agricultural machinery The sliding friction between the roller inner hole and the blade root circle is large, and the floating oil is cut, resulting in thousands of friction.

Precautions can be taken for the above reasons.

(2) The speed does not increase

① Same as ① and ② for "insufficient output torque".

② The size transmission gear is damaged, which reduces the precision of roller oil distribution, leading to part of the oil flowing in and out of the cavity.

③ The gasoline pump does not provide enough fuel.

Preventive measures can be taken based on the above reasons.

Increasing the total flow can certainly increase the speed, but more or less it will harm Cycloid hydraulic motor The service life of. However, if it is within its maximum power range, it is OK. If the steam pressure reaches the rated working pressure, and the speed is increased, it will exceed the range of output power it can bear, so the cycloid will naturally Hydraulic motor Its service life is harmful to some extent. It's like trying to eat too much when you can't eat it. As a result, your stomach will be damaged.

The total lifting flow is only limited to the lifting speed of 500 to 900, so it is proposed to replace the motor with a new model and specification. The total flow of the cycloidal hydraulic motor is raised to a certain level, and the speed is not easy to rise indefinitely. The internal steam pressure rises, and the internal leakage expands, resulting in an immediate decrease in efficiency or motor damage.

How can the rotor pair of the cycloidal hydraulic motor and the misaligned motor turn over? The stator motor rotor is correct. The relative position of the motor rotor and the oil slinger is incorrect. The cycloidal motor is divided into two types: shaft flow distribution and inner hole flow distribution.
