Problems solved by technology

Such an installation method is not suitable for the reducer casing of a large-capacity washing machine, mainly because, due to the large volume of the reducer casing of a large-capacity washing machine, if it is made of one-piece molding, a thick casing is required in order to meet the strength requirements of the installation. wall, which is not only costly, but also not conducive to manufacturing and installation

Embodiment 1

[0046] Such as figure 1 As shown, the clutch device described in this embodiment includes a dehydration pin 6 installed at the lower end of the wheel train housing 5, a clutch sleeve 3 installed at the input shaft sleeve 2 and rotating integrally with the input shaft sleeve 2, and a clutch sleeve installed at the lower end of the lower end cover 23. The brake pin 4 and the driving clutch sleeve 3 are respectively connected to / disconnected from the dehydration pin 6 and the brake pin 4;

[0047] In the washing state, the drive unit controls the clutch sleeve 3 to be connected to the brake pin 4 and to be disconnected from the dehydration pin 6 , and in the dehydration state, to control the clutch sleeve 3 to be connected to the dehydration pin 6 and to be disconnected from the brake pin 4 .

[0048] At least one first bearing 11 is arranged on the input shaft sleeve 2 of the present invention, specifically, no less than two first bearings 11 are encapsulated at the assembling p...

Embodiment 2

[0050] Such as figure 2 As shown, the clutch device described in this embodiment includes a dehydration pin 6 installed on the input shaft 1, a clutch sleeve 3 installed on the input shaft sleeve 2 and rotating integrally with the input shaft sleeve 2, and a braking device installed at the lower end of the lower end cover 23. Pin 4 and driving clutch sleeve 3 are respectively connected to / disconnected with dehydration pin 6 and brake pin 4;

[0051] In the washing state, the drive unit controls the clutch sleeve 3 to be connected to the brake pin 4 and to be disconnected from the dehydration pin 6 , and in the dehydration state, to control the clutch sleeve 3 to be connected to the dehydration pin 6 and to be disconnected from the brake pin 4 .

[0052] At least one fourth bearing 24 is arranged between the wheel train casing 5 and the input shaft sleeve 2 in the present invention. In the present invention, by providing more than one fourth bearing 24, the bearing support fu...

Embodiment 3

[0054] In the above embodiment, the clutch sleeve 3 is slidably installed on the input shaft sleeve 2 up and down, and rotates integrally with the input shaft sleeve 2; the clutch sleeve 3 is controlled by the drive unit to slide up and down to be splined with the dehydration pin 6 and the brake pin 4, When disconnected, the drive unit includes a return spring and a device to drive the action of the clutch sleeve. The device is electromagnetically driven or mechanically driven, such as a shift fork structure.

Abstract

The invention provides a bearing installation structure of a decelerating clutch. The bearing installation structure comprises the decelerating clutch. The decelerating clutch is mostly composed of an input shaft, an output shaft, a dehydration shaft, an input shaft sleeve, a decelerator, a gear train shell, a clutch device and a shell. The decelerator is arranged in the gear train shell. The input shaft is installed into an input shaft sleeve. The output shaft is installed into the dehydration shaft. The shell comprises two parts including an upper end cover and a lower end cover. The upper end cover and the lower end cover are fixedly connected to form a cavity, in which the gear train shell is arranged. At least one second bearing is packaged between the upper end cover and the dehydration shaft. At least one third bearing is packaged between the lower end cover and the gear train shell.The bearing installation structure of the decelerating clutch has following beneficial effects: according to an assembly relation between the upper end cover and the output shaft and an assembly relation between the lower end cover and the input shaft, at least one second bearing is packaged between the upper end cover and the dehydration shaft and at least one third bearing is packaged between the lower end cover and the gear train shell, so that bearing installation and support problems of the output shaft and the input shaft are solved.

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 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 accordin...
