Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, specifically to a low-noise oil pump motor unit. Background Technology

[0002] A hydraulic pump is a power component of a hydraulic system. It is driven by an engine or electric motor, draws oil from the hydraulic tank, pressurizes it, and discharges it to the actuator. Hydraulic pumps are classified into gear pumps, piston pumps, vane pumps, and screw pumps according to their structure.

[0003] In existing oil pumps, since an engine or electric motor is used as the drive unit, the power needs to be transmitted in the hydraulic circuit. There will be certain connection gaps between different components. As a power output device, the engine or electric motor often needs to operate at high speed to provide strong hydraulic pressure, which will generate a certain amount of vibration. This will cause the transmission rod between the engine and the hydraulic station to resonate and generate noise. Utility Model Content
