Cycloid hydraulic motor

Cycloid hydraulic motor

(l) Scope. This standard specifies the structural type, basic parameters, technical requirements, test methods, inspection rules, marks and packaging of cycloid hydraulic motors. This standard is applicable to cycloidal hydraulic motors with hydraulic oil or other mineral oil with equivalent performance as medium.

(2) Definition

① Rated pressure. Continuous operation within the specified speed range, and can ensure the design life of the maximum input pressure.

② No load pressure. Input pressure not exceeding 10% of rated pressure.

③ Rated speed. Under the condition of rated pressure and specified back pressure, it can operate continuously and guarantee the maximum speed of design life.

④ Minimum speed. The rated speed can be kept stable and minimum.

⑤ Displacement. Output volume of oil per revolution of output shaft.

⑥ No load displacement. Actual displacement at no-load pressure.

⑦ Rated working condition. Rated pressure and rated speed.

⑧ Starting torque. The minimum effective torque obtained by the shaft of a motor from standstill to start-up under specified operating conditions and given pressure difference.
