Abstract

The invention provides a deceleration clutch bearing mounting structure, which comprises an impeller shaft, a dehydration shaft, a gearbox and an outer shell, wherein the gearbox is set inside the outer shell; the impeller shaft and the dehydration shaft are set at the same shaft and the impeller shaft is rotatingly set inside the dehydration shaft; one ends of the impeller shaft and the dehydration shaft extend into the gearbox and the other ends of the impeller shaft and the dehydration shaft extend out of the outer shell; the outer shell comprises an upper end cover and a lower end cover; the upper end cover is a separated-type structure which comprises a cover body of the upper end cover and an upper end cover main body; at least one bearing is sealed between the cover body of the upper end cover and the dehydration shaft; the gearbox comprises a brake wheel and a wheel system set inside the brake wheel; and at least one bearing is sealed between the brake wheel and the dehydration shaft. According to the invention, aiming to the structural characteristics of the separated-type deceleration clutch outer shell, the bearing support effects to the impeller shaft and the dehydration shaft are realized by respectively sealing at least one bearing between the cover body of the upper end cover and the brake wheel and the dehydration shaft.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a bearing installation structure for a deceleration clutch. Background technique [0002] As a daily household appliance, washing machine liberates people from the labor of doing laundry, so it is very popular among users. However, with the rapid development of society, people have higher and higher requirements for washing machines, including people's higher and higher requirements for the capacity of washing machines. Therefore, large-capacity washing machines are thus produced. [0003] Since the washing capacity of the large-capacity washing machine is larger, more power is needed to drive the washing, so a more powerful drive motor is required to provide power. In order to ensure the stability and reliability of power transmission, the length and diameter of the input shaft and output shaft of the deceleration clutch of the large-capacity washing machine must be increased ac...
