Abstract

The invention relates to a nonstandard thin-wall waterproof bearing, comprising an outer ring (1), an inner ring (2), a steel ball (3) and a nylon retainer (4). The steel ball (3) is arranged between the outer ring (1) and the inner ring (2) through the nylon retainer (4); an external ball groove (11) adaptive to the steel ball (3) is arranged in the middle of the inner side of the outer ring (1); the outer side of the inner ring (2) is provided with a partial groove (21) adaptive to the steel ball (3); the partial groove (21) is arranged on the bias place on the outer side of the inner ring (2); a section of bias part (22) offsetting out of one side of the outer ring (1) is provided when the inner ring (2) is matched with the outer ring (1); and the external diameter surface of the bias part (22) and a sealing waterproof rubber ring on a host using the bearing form contacting interference fit. The nonstandard thin-wall waterproof bearing has the advantages that the weight of the bearing is reduced by 15-25%, the production cost and difficulty are greatly reduced and the use effect is effectively improved in comparison with the traditional bearing.

Description

technical field [0001] The invention relates to a bearing, in particular to a non-standard thin-wall waterproof bearing. Background technique [0002] In the prior art, bearings generally include sealing rings, outer rings, nylon cages, steel balls and inner rings, which mainly have the following disadvantages: the width of the outer ring and the inner ring are the same, and the outer ring needs to be processed The sealing groove, and the sealing ring must also be assembled; the groove for fixing the steel ball on the inner ring is in the middle, and it is not biased relative to the outer ring; the height of the bottom surface of the nylon cage is limited by the position of the sealing space, which is suitable for thin-walled products. The deformation and strength of the nylon cage are very unfavorable. Contents of the invention [0003] The purpose of the present invention is to provide an embodiment of a non-standard thin-walled waterproof bearing, in order to solve the...
