Title:
HIGH-PRESSURE CLEANING MACHINE MOTOR PUMP UNIT SUITABLE FOR INTERNAL MESHING DECELERATION TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/175334
Kind Code:
A1
Abstract:
A high-pressure cleaning machine motor pump unit suitable for internal meshing deceleration transmission, comprising a high-pressure pump assembly (100), an oil cylinder assembly (200) and a high-pressure cleaning machine motor unit (300); the oil cylinder assembly comprises a bull gear (240), a gear shaft (230), a swash plate and a thrust bearing (250); the high-pressure pump assembly comprises a pressurizing element; an output end of the high-pressure cleaning machine motor unit is provided with a pinion (360), and the pinion (360) internally meshes with the bull gear (240) to decelerate and then drives the pressurizing element to reciprocate; the high-pressure cleaning machine motor unit (300) comprises a motor support (310), and a motor stator (320) is mounted on a motor stator core mounting surface (317) of the motor support (310) and is connected to the high-pressure washing machine motor unit (300) and the oil cylinder assembly (200) by means of the motor support (310); and a motor gear box comprises a gear grease limiting wall (313). The high-pressure cleaning machine motor pump unit employs internal meshing transmission, a deceleration device has a compact structure and grease can be prevented from splashing.
