Embodiment 1

[0059] see Figure 1-Figure 6 As shown, the present embodiment provides a washing machine outer tub 10, the bottom of which is provided with a bearing support seat 11, the bearing support seat 11 is provided with a bearing chamber, and an oil seal 15, a front bearing 13 and a rear bearing are installed in the bearing chamber. 14. The bearing chamber is provided with a first support structure 16 for providing support to the inner ring of the front bearing 13 and preventing the inner ring of the front bearing 13 from being damaged by force during the installation of the inner barrel shaft 23 .

[0060] In the above scheme, by setting the first support structure 16 in the bearing chamber, it is beneficial to provide the bearing inner ring support force during the installation of the inner barrel shaft 23, and solve the problem caused by the complicated positioning and force-bearing structure of the current tight-fit bearing press-fitting equipment. The cost of press-fitting equip...

Embodiment 2

[0075] This embodiment provides a washing machine inner and outer tub 10 assembly method applied to the washing machine outer tub 10 in the first embodiment, wherein, because the present invention is provided in the bearing chamber to provide support for the inner ring of the front bearing 13, preventing the installation of the inner tub During the process of the shaft 23, the inner ring of the front bearing 13 is stressed and the first support structure 16 is damaged, thereby facilitating press-fitting, effectively reducing equipment costs, and simplifying the assembly method of the inner and outer barrels 10 . The method for assembling the inner and outer tubs 10 includes the following steps:

[0076] S1, sequentially press-fit the front bearing 13 and the oil seal 15 into the bearing chamber in the bearing seat, so that the front bearing 13 is fixed in the front bearing chamber 17, and the oil seal 15 is fixed on the outside of the front bearing 13;

[0077] S2, the rear be...

Embodiment 3

[0080] see figure 1 as well as Figure 7-Figure 9As shown, the present embodiment provides another washing machine outer tub 10, the bottom of which is provided with a bearing support seat 11, the bearing support seat 11 is provided with a bearing chamber, and an oil seal 15, a front bearing 13 and a rear bearing chamber are installed in the bearing chamber. Bearing 14, the bearing chamber is provided with a first support structure 16 for providing support to the inner ring of the front bearing 13 to prevent the inner ring of the front bearing 13 from being damaged by force during the process of installing the inner barrel shaft 23. The first supporting structure 16 includes the abutment pieces 24 arranged at the two ends of the bearing chamber respectively abutting against the inner ring of the front bearing 13 and the inner ring of the rear bearing 14. 23 in the process, accept the external structure to provide support;

[0081] Preferably, the bearing chamber includes a f...

Abstract

The invention discloses an outer barrel of a washing machine and a method for assembling the inner and outer barrels of the washing machine. A bearing support seat is arranged at the bottom of the outer barrel, and a bearing chamber is arranged inside the bearing support seat. An oil seal, a front bearing and a rear bearing are installed in the bearing chamber. For bearings, the bearing chamber is provided with a first support structure for providing support to the inner ring of the front bearing to prevent the inner ring of the front bearing from being damaged by force during the installation of the inner barrel shaft; The first support structure is conducive to providing the support force of the inner ring of the bearing during the installation of the inner barrel shaft, which solves the problem of high cost of press-fitting equipment caused by the complex positioning and force-bearing structure of the current tight-fitting bearing press-fitting equipment. At the same time, it can Realize the press-fitting of double tight fit bearings.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an outer tub of a washing machine and a method for assembling the inner and outer tubs of the washing machine. Background technique [0002] At present, the bearings and shafts of the drum washing machine are matched in two ways: loose fit and tight fit, that is, clearance fit and interference counterweight. The front and rear two bearings are installed in the bearing support seat, and the bearing outer ring and the bearing inner wall of the bearing support seat are interference fit. Among them, the parts with interference fit need to be installed with equipment for pressing. [0003] The tight fit press-fitting method of the existing scheme, one is a split tripod structure, that is, the tripod body and the shaft are separated, the shaft is first pressed into the bearing, and then the inner barrel with the tripod body is passed through the bolts Fasten to the shaft. In this...
