Abstract

An outer drum bearing block of a drum washer comprises a bearing block body. Reinforcing ribs are peripherally arranged at intervals on the bearing block body. The outer drum bearing block is characterized in that the cross section of each reinforcing rib is in a transverse T shape, a body part of each reinforcing rib radially protrudes outward along the bearing block body, an extending retainer edge parallel to an axis of the bearing block body is arranged on the outer side of each body part, and a groove is formed between the retainer edge and the outer periphery of the bearing block body. Compared with the prior art, the outer drum bearing block has the advantages that the structure of the traditional reinforcing ribs is changed, the retainer edge is added to each outwardly protruding reinforcing rib, and thereby axial and radial positioning of the bearing block is guaranteed, contact area of the bearing block when being joined with an outer drum of the washer is increased, joint force and joint strength are enhanced, reliable connection of the bearing block with the outer drum of the washer is guaranteed, separation of the bearing block and the outer drum in high-speed rotation is avoided, and product performance is improved.

Description

The outer bucket of roller washing machine bearing block

Technical field

The utility model relates to the outer bucket bearing block of a kind of bearing block, particularly a kind of roller washing machine.

Background technology

In the prior art, the combination of outer bucket of roller washing machine and bearing block only depends on the convex tendon on the bearing block periphery, it as the patent No. disclosed roller washing machine bearing block in the Chinese utility model patent " roller washing machine bearing block " of ZL200520073798.9, this roller washing machine bearing block changes cast iron materials into by original aluminum alloy materials, with wall thickness be reduced to thick come about 2/5, also increased reinforcement simultaneously.But the reinforcement in the above-mentioned patent all is that bond strength is little radially to outer lug, after barrel knot closes outside the plastics of bearing block and washing machine, under high speed conditions, is easy to generate the outer bucket of plastics and bearing block slip vertically and separates.

Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of intensity height, with the outer barrel knot outer barrel of bearing block of big roller washing machine of making a concerted effort.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the outer bucket of a kind of roller washing machine bearing block, include the bearing block body, this bearing block body has the reinforcement that is provided with at interval along circumferential arrangement, it is characterized in that: the cross section of described reinforcement is the T shape of horizontally set, the main part of this reinforcement is radially outward protruding along described bearing block body, and, extending on the lateral surface of this main part has the rib that parallels with the axis direction of described bearing block body, forms groove between the outer peripheral face of described rib and described bearing block body.

As preferably, the lateral surface of described rib and described reinforcement main part is one-body molded, and this rib extends to both sides respectively along the vertical direction of described main part.

As further preferred, the lateral surface of described rib and described reinforcement main part is one-body molded, and this rib circumferentially extends to both sides respectively along described main part.

Compared with prior art, advantage of the present utility model is: changed traditional reinforcing rib structure, on the reinforcing rib structure of evagination, increase rib, guaranteed that bearing block vertically and location radially, make bearing block when combining, can increase contact area, improve adhesion and bond strength, guarantee that bearing block and the reliable of outer barrel of washing machine are connected with outer barrel of washing machine, prevent both separation down of rotation at a high speed, improved the performance of product.

Fig. 1 is the perspective view of the utility model embodiment.

Fig. 2 is that A-A shown in Figure 1 is to cutaway view.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, the bearing block of present embodiment is installed on the outer bucket of roller washing machine, and this bearing block includes bearing block body 1; There is the reinforcement 2 that is provided with at interval the upper and lower of bearing block body 1 along circumferential arrangement respectively, wherein, the cross section that is positioned at the reinforcement 2 of bearing block 1 bottom is the T shape of horizontally set, the main part 21 of this reinforcement 2 is along the projection radially outward of bearing block body 1, and, also extend on the lateral surface of this main part 21 rib 22 that parallels with the axis direction of bearing block body 1 is arranged, rib 22 is integrated with the main part 21 of reinforcement 2, the bearing of trend of rib 22 can for along the vertical direction of the main part 21 of reinforcement 2 respectively up and down both sides extend (referring to Fig. 2), also can extend (not shown) in both sides to the left and right, form the gap between the outer peripheral face of rib 22 and bearing block body 1 and can form groove 3 for circumferential difference along the main part 21 of reinforcement 2.

Traditional bearing block is in order to increase and the adhesion of outer bucket, can only adopt the way that increases bearing block diameter and reinforcement quantity to remedy, the bearing block reinforcement 2 of present embodiment has adopted the hook-shaped convex rib structure of band rib 22, make bearing block and outer barrel of washing machine material to combine together better, both solved the adhesion problem of the outer bucket of bearing block and plastics, the high heat of having avoided under rotation at a high speed, producing make bearing block and outside barrel possibility of separating, also saved simultaneously the bearing block material, adopt the bearing block strength ratio ordinary construction of present embodiment reinforcement 2 structures strong more than 50%, and material has saved 20%, has improved the performance of product effectively.

Claims

1. the outer bucket of roller washing machine bearing block, include the bearing block body, this bearing block body has the reinforcement that is provided with at interval along circumferential arrangement, it is characterized in that: the cross section of described reinforcement is the T shape of horizontally set, the main part of this reinforcement is radially outward protruding along described bearing block body, and extending on the lateral surface of this main part has the rib that parallels with the axis direction of described bearing block body, forms groove between the outer peripheral face of described rib and described bearing block body.

2. the outer bucket of roller washing machine according to claim 1 bearing block, it is characterized in that: the lateral surface of described rib and described reinforcement main part is one-body molded, and this rib extends to both sides respectively along the vertical direction of described main part.
