Hydraulic motor

Abstract

The invention relates to the field of hydraulic motors, in particular to a hydraulic motor. The hydraulic motor comprises a shell, wherein one side of the shell is fixedly connected to a front cover through bolts, a side partition plate is arranged on the other side of the shell, a rear cover is arranged on one side of the side partition plate, the side partition plate and the rear cover are fixedly connected to the shell through bolts, a bearing partition plate is fixedly connected in the front cover, an output shaft is connected in the bearing partition plate in a sleeving mode, a fixed rotor is fixedly connected to one end of the output shaft, a rotor sleeve is connected outside the the fixed rotor in a sleeving mode, one end of the rotor sleeve is fixedly connected to a transmission shaft, and a smooth groove is formed in an inner ring of the rotor sleeve. By arranging a shaft sleeve, and combing a top structure curved plate, a bottom structure curved plate, a left structure curved plate and a right structure curved plate, a certain eccentric rotation can be generated in the rotating process of the shaft sleeve, and the driving effect of the fixed rotor is improved; and by arranging the top structure curved plate, the bottom structure curved plate, the left structure curved plate and the right structure curved plate, liquid can conveniently to achieve the effect of driving shaft sleeve by multiple channels, and the driving effect is improved.

Description

technical field [0001] The invention relates to the field of hydraulic motors, in particular to a hydraulic motor. Background technique [0002] The hydraulic motor is an actuator of the hydraulic system. It converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. The liquid is the medium for transmitting force and motion. It is mainly used in injection molding machinery and ships. , Hoists, engineering machinery, construction machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical, port machinery, etc. [0003] The hydraulic channel inside the traditional hydraulic motor is single. In the plateau area, the low atmospheric pressure affects the surface tension of the liquid, resulting in a single fluid drive effect that is not enough to drive the motor strongly, and the internal backflow of the liquid does not form multiple liquid drive effects, resu...

AI Technical Summary

Problems solved by technology

[0003] The hydraulic channel inside the traditional hydraulic motor is single. In the plateau area, the low atmospheric pressure affects the surface tension of the liquid, resulting in a single fluid drive effect that is not enough to drive the motor strongly, and the internal backflow of the liquid does not form multiple liquid drive effects, resulting in liquid drive rotation. The effect is low; the contact parts of the rotor during the eccentric movement are mostly curved, which causes the device not to have a good centrifugal swing effect, and it is easy to shake and affect the driving effect and stability of the motor
