Abstract
The utility model discloses a bearing, in particular to a deep groove ball bearing on a snowmobile on a snowfield or in an environment with snow water. The deep groove ball bearing comprises an outer ring (1), an inner ring (2), a steel ball (3), sealing rings (4) and a holder (5), wherein the steel ball (3) is fixed between the outer ring (1) and the inner ring (2) through the holder (5); the sealing rings (4) are arranged on the two sides of the holder (5); an inner lip (5) and an outer lip (6) are arranged at the contact position between each sealing ring (4) and the inner ring (2); the inner lip (5) is in interference fit with an inclined plane (22) of the inner ring (2); and the outer lip (6) is in interference fit with a seam allowance surface (21) of the inner ring (2). In the utility model, due to the interference fit between the inner lip and the inclined plane of the inner ring and the interference fit between the outer lip and the seam allowance surface of the inner ring, the deep groove ball bearing has excellent dustproof and waterproof capabilities; and the snowmobile often used on the snowfield or in the environment with snow water has relatively long service life.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of deep groove ball bearing on the snowmobile under snowfield or the snowy water environment.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.At present mostly the quality requirement of bearing is to be embodied in and requires its long service life under the high-speed rotation; Also have when working environment is relatively more abominable and can play the effect of dust and water protection preferably, the snowmobile that for example under be everlasting snowfield or snowy water environment, uses is just very high about the requirement in water proof and dust proof and working life to bearing.But in the present conventional bearing, can't satisfy the requirement of snowmobile dustproof and waterproof and long service life at all, and can only use external expensive imported bearing.
The model utility content
The purpose of the utility model is to provide a kind of mode of execution of deep groove ball bearing, can solve the existing bearing that is used for snowmobile with expectation and can not play well dustproof, waterproof action and cause short problem in its working life.
For addressing the above problem, the technological scheme that the utility model is taked is:
A kind of deep groove ball bearing; Comprise outer ring, inner ring, steel ball, seal ring and retainer; Described steel ball is fixed between outer ring and the inner ring through retainer, and seal ring is arranged on the both sides of retainer, and described seal ring and inner ring touching position are provided with epipharynx and outer lip; The inclined-plane interference fit of described epipharynx and inner ring, the seam face interference fit of described outer lip and inner ring.
For making the utility model play better technique effect:
Technological scheme further is that the magnitude of interference of the inclined-plane interference fit of above-mentioned epipharynx and inner ring is 0.20mm～0.30mm.
Technological scheme further is that the magnitude of interference of the inclined-plane interference fit of above-mentioned epipharynx and inner ring is 0.25mm.
Technological scheme further is that the magnitude of interference of the seam face interference fit of above-mentioned outer lip and inner ring is 0mm～0.10mm.
Technological scheme further is that the magnitude of interference of the seam face interference fit of above-mentioned outer lip and inner ring is 0.05mm.
Adopt the beneficial effect that technique scheme produced to be: the utility model deep groove ball bearing is owing to there is the inclined-plane interference fit of epipharynx and inner ring; And the seam face interference fit of outer lip and inner ring; It has had very good dustproof and waterproof ability; The snowmobile that under be everlasting snowfield or snowy water environment, uses has long working life.
