Abstract

The invention discloses an internal engagement hydraulic motor capable of achieving four-quadrant operation, and belongs to the technical field of medium delivery. A first pump and a second pump are arranged correspondingly, the two pumps are each internally provided with a symmetrical structure composed of a crescent plate, an inner gear ring, an outer gear and two oil ports, and a special oil drain hole and a special oil drain channel are formed in a rotating shaft correspondingly so that the internal engagement hydraulic motor can achieve four-quadrant operation under a pump mode and a motor mode, and hydraulic oil entering a bearing area along with the rotating shaft can be effectively drained. The internal engagement hydraulic motor is simple in structure, low in manufacturing cost and good in reliability, can effectively achieve four-quadrant operation, is high in functionality and wide in application range, and has good application prospects and popularization value.

Description

technical field

[0001] The invention belongs to the technical field of medium conveying, and in particular relates to an internal meshing hydraulic motor capable of four-quadrant operation. Background technique

[0002] In industrial production and daily life, hydraulic systems are widely used. In hydraulic systems, hydraulic pumps and hydraulic motors often play a very important role. Among them, the hydraulic pump is the power component of the hydraulic system, which is often driven by the engine or electric motor, sucks the oil from the hydraulic oil tank, forms pressure oil and sends it to the actuator; and the hydraulic motor is an actuator of the hydraulic system. The hydraulic pressure provided by the hydraulic pump can be transformed into the mechanical energy (torque and rotational speed) of its output shaft to correspondingly drive the corresponding components to complete the corresponding process.

[0003] Generally, the hydraulic motor and the hydraulic pump ar...
