Problems solved by technology

[0003] According to different equipment operation requirements and purposes, the hydraulic transmission structure has different forms. Among them, the hydraulic pump station is a typical hydraulic transmission structure. The hydraulic pump station is mainly composed of a fuel tank, a motor, and an oil pump. The motor shaft and the oil pump shaft Connection, when the motor shaft and the oil pump shaft are adjusted incorrectly or the foundation of the motor oil pump is loose, it will cause wear and loosening, which will make the connection position between the motor shaft and the oil pump shaft constantly loose, which will cause greater damage during the operation of the unit. If the noise is serious, it will lead to severe wear of the connecting position between the motor shaft and the oil pump shaft and cause the equipment to stop

Abstract

The invention relates to a connecting structure of an inner shaft oil pump motor. The connecting structure comprises a first shaft sleeve connected with a motor shaft, a second shaft sleeve connectedwith an oil pump shaft, and a connecting assembly connected with the first shaft sleeve and the second shaft sleeve; and key grooves are formed in the first shaft sleeve and the second shaft sleeve. The connecting assembly is used for limiting the rotation freedom degree around the central axis of the first shaft sleeve and / or the second shaft sleeve. According to the connecting structure of the inner shaft oil pump motor, when the motor operates, vibration caused by assembly errors between shafts can be relieved, and the service life of the motor oil pump cannot be affected.

Description

technical field [0001] The invention relates to the technical field of hydraulic transmission, in particular to a connection structure of an inner shaft oil pump motor. Background technique [0002] Hydraulic transmission refers to a transmission method that uses liquid as the working medium for energy transmission and control. In liquid transmission, according to the different forms of energy transmission, it is divided into hydraulic transmission and hydraulic transmission. Hydraulic transmission is mainly a transmission method that uses liquid kinetic energy for energy conversion, such as a hydraulic coupling and a hydraulic torque converter. Hydraulic transmission is a transmission method that uses liquid pressure energy for energy conversion. The use of hydraulic transmission technology in machinery can simplify the structure of the machine, reduce the quality of the machine, reduce material consumption, reduce manufacturing costs, reduce labor intensity, and improve ...
