Description

Technical Field

[0001] The utility model relates to the field of hydraulic motors, in particular to a hydraulic motor with a high-strength shell. Background Technique

[0002] A hydraulic motor is an actuator in a hydraulic system that converts the hydraulic pressure energy provided by a hydraulic pump into the mechanical energy of its output shaft. The liquid is the medium for transmitting force and motion. A hydraulic motor, also known as an oil motor, is mainly applied to injection molding machinery, ships, hoisting machines, construction machinery, building machinery, coal mining machinery, mining machinery, metallurgical machinery, ship machinery, petrochemical industry, and port machinery, etc.

[0003] According to its structural type, hydraulic motors can be divided into gear type, vane type, piston type, and other types. According to the rated speed of the hydraulic motor, they are divided into two categories: high-speed and low-speed. A high-strength shell is provided outside the hydraulic motor to achieve drive under high hydraulic pressure. However, the high-strength shell has a large thickness, which is not conducive to the heat dissipation of the hydraulic motor, resulting in a high temperature of the shell when the hydraulic motor is in use. Therefore, we propose a hydraulic motor with a high-strength shell to solve the above problems. Content of the Utility Model
