CN202023084U - Bearing pedestal - Google Patents

Abstract

The utility model relates to a bearing pedestal, in particular to a bearing pedestal of a washing machine. In the utility model, a ring groove is arranged on the upper end surface and the lower end surface of the bearing pedestal respectively, and the centers of the ring grooves coincide with the center of the bearing pedestal. In accordance with the technical scheme, a ring groove is arranged on the upper end surface and the lower end surface of the bearing pedestal respectively, so that when the bearing pedestal is in injection molding, the pressure generated by the bearing pedestal can be released through the ring grooves, thereby avoiding the deformation of a bearing hole on the bearing pedestal and facilitating the press mounting of the bearing.

Description

Bearing block

Technical field

The utility model relates to a kind of bearing block, relates to a kind of washing machine bearing block specifically.

Background technology

At present, the bearing block of traditional its washtub of fully automatic roll type washing machine normally is directly injection-moulded on the washtub, washtub is when injection moulding, because the variation of technologies such as injection pressure, injection speed, variation of ambient temperature, plastic shrink all can cause bearing block discontinuity when injection moulding, cause bearing block after moulding, can cause distortion, be unfavorable for press-fiting of bearing, and can influence the life-span of complete machine.

Summary of the invention

The purpose of this utility model provides a kind of bearing block, can effectively solve the distortion that causes owing to the injection moulding reason.

For achieving the above object, the utility model has adopted following technical scheme: upper and lower two end faces of bearing block offer cannelure respectively, and the center of cannelure and the center of bearing block match.

Spacing between the inside and outside wall of the utility model cannelure is not less than 10MM.

As shown from the above technical solution, the utility model is by offering cannelure on upper and lower two end faces of bearing block, the pressure that bearing block produced is just discharged by cannelure during injection moulding like this, avoided the distortion in bearing block upper bearing (metal) hole, make bearing press mounting convenient.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Bearing block as shown in Figure 1 and Figure 2, upper and lower two end faces of bearing block 10 offer cannelure 11 respectively, the center of the center of cannelure 11 and bearing block 10 matches, as preferred version of the present utility model, spacing between the inside and outside wall of cannelure 11 is not less than 10MM, and promptly the difference in the inside and outside footpath of cannelure 11 remains on more than the 10MM at least.

During injection moulding, the pressure of plastics acts directly on the outer wall of bearing block 10, then arrive cannelure 11, owing to have the space between the inside and outside wall of cannelure 11, in the time of can effectively reducing injection moulding like this to the pressure of dead eye 12, the distortion of dead eye 12 is in the acceptable margin of tolerance, is beneficial to the installation of bearing, also do not influence the machine life of washing machine simultaneously.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.

Claims (2)

1. bearing block, it is characterized in that: upper and lower two end faces of bearing block (10) offer cannelure (11) respectively, and the center of the center of cannelure (11) and bearing block (10) matches.

2. bearing block according to claim 1 is characterized in that: the spacing between the inside and outside wall of described cannelure (11) is not less than 10MM.
