Description

Waterproof rolling bearing mounting structure

Technical Field

The utility model relates to a waterproof rolling bearing mounting structure which is mainly used for mounting a rolling bearing in a motor.

Background

The bearing chamber and the rolling bearing of the motor have a fit clearance after being assembled, and even if the waterproof rolling bearing is adopted, the bearing and the shaft can only be prevented from being waterproof, and the inner ring and the outer ring of the bearing can not be prevented from flowing into the motor from the space between the outer ring of the rolling bearing and the bearing chamber.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a waterproof rolling bearing mounting structure capable of achieving all-dimensional waterproofing.

The technical scheme of the utility model is as follows:

the utility model provides a waterproof antifriction bearing mounting structure, includes waterproof antifriction bearing and bearing room, and the indoor division of bearing has bearing room hole, waterproof antifriction bearing assembles in the bearing room hole, and has fit clearance between waterproof antifriction bearing's outer lane and the bearing room hole, and the outer terminal surface of bearing room hole is equipped with the annular terminal surface of round, is equipped with seal ring between terminal surface and waterproof antifriction bearing.

Preferably, the sealing washer is a silica gel washer or a rubber washer, the thickness of the sealing washer is larger than the distance between the end face and the waterproof rolling bearing, and after the sealing washer is installed, the sealing washer can be tightly matched with the end face and the waterproof rolling bearing.

Preferably, the outer ring of the sealing washer is in close clearance fit with the inner bore of the bearing chamber. After the two side faces of the sealing washer and the outer ring end face of the waterproof rolling bearing are laminated and compressed on three faces, the sealing performance is guaranteed, water is prevented from entering, and meanwhile abrasion caused by working jitter of the motor can be avoided.

Preferably, the diameter of the inner ring of the sealing washer is larger than that of the inner ring of the waterproof rolling bearing. This design makes seal ring for the compression between terminal surface and bearing, and is not only more pleasing to the eye, even long-time and water contact in addition, seal ring also can not receive the influence, because seal ring extends to the inner bore wall all the time, therefore seal ring's main part is still tightly pressed between bearing room terminal surface and waterproof antifriction bearing's outer lane terminal surface, can not exert an influence to waterproof sealing.

The utility model has the beneficial effects that:

according to the utility model, only one sealing washer is arranged between the end face of the outer end of the bearing chamber and the waterproof rolling bearing, so that water can be effectively prevented from flowing into the motor from the space between the outer ring of the rolling bearing and the inner hole of the bearing chamber, and omnibearing waterproof is realized.

Drawings

The utility model will now be described, by way of example, with reference to the accompanying drawings, in which:

FIG. 1 is a schematic of the present invention.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings.
