Publication number: 20220260076Abstract: An orbiting scroll plate driving assembly provided by the present application includes a main shaft (7), a tail driving shaft (6), and an eccentric shaft sleeve (5). The tail driving shaft (6) is eccentrically connected to the main shaft (7), and the eccentric shaft sleeve (5) is rotatably sleeved on the tail driving shaft (6). The orbiting scroll plate driving assembly further includes a limiting portion (14). The limiting portion (14) is disposed on the tail driving shaft (6), and provided with a first limiting portion protrusion (141). The eccentric shaft sleeve (5) is provided with an eccentric shaft sleeve groove (51). The first limiting portion protrusion (141) is correspondingly inserted into the eccentric shaft sleeve groove. A circumferential size of the eccentric shaft sleeve groove (51) is larger than a circumferential size of the first limiting portion protrusion (141).Type: ApplicationFiled: June 30, 2020Publication date: August 18, 2022Applicant: GREE GREEN REFRIGERATION TECHNOLOGY CENTER CO., LTD.
