Abstract
The utility model belongs to the technical field of the bearing production technique and specifically relates to a miniature precision bearing includes bearing outer loop, annular slide rail and inner ring, the spout has been seted up to relative both sides on the bearing outer loop inner wall, first ball groove has been seted up to bearing outer loop inner wall, slide rail slidable connects in the spout, slide rail one side rigid coupling has the wedge, the slot has been seted up on the wedge lateral wall, second ball groove has been seted up to inner ring one side, inner ring both sides rigid coupling has the inserted block, inserted block slidable connects in the slot. This miniature precision bearing passes through the slide rail and closely cooperates with the inner ring, and the inserted block plays the spacer bush effect to bearing outer ring inner circle after packing into the slot, prevents that external dust and impurity from getting into inside the bearing outer ring.
Description
Technical Field
The utility model relates to a bearing production technical field especially relates to a miniature precision bearing.
Background
The bearing is a precise part, but the working environment is complex, 70% of the advanced failures of the bearing are caused by abnormal abrasion or poor rotation of a raceway due to impurities entering the inside of the bearing, and meanwhile, the bearing sealing ring is made of rubber, is soft and easy to deform and age, has poor sealing effect after deformation, is easy to fall off after continuous stress, and causes poor sealing of the bearing and advanced failures.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect that impurities are easy to enter inside the bearing in the prior art, and providing a miniature precision bearing.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the design is a miniature precision bearing, which comprises a bearing outer ring, an annular slide rail and an inner ring, wherein the slide groove is formed in two opposite sides of the inner wall of the bearing outer ring, a first ball groove is formed in the inner wall of the bearing outer ring, the slide rail is slidably connected in the slide groove, a wedge block is fixedly connected to one side of the slide rail, a slot is formed in the side wall of the wedge block, a second ball groove is formed in one side of the inner ring, an insert block is fixedly connected to two sides of the inner ring, and the insert block is slidably connected in the slot.
Preferably, fix through the supporting shoe between the slide rail, the supporting shoe includes curved wearing parts and wedge-shaped fastener, the fastener rigid coupling is in on the wearing parts outer wall, the fastener both sides support and lean on two between the wedge.
Preferably, a plurality of steel balls are slidably connected between the first ball groove and the second ball groove.
The utility model provides a pair of miniature precision bearing, beneficial effect lies in: the miniature precision bearing is closely matched with the inner ring through the sliding rail, and the insert block plays a role of a spacer bush for the inner ring of the bearing outer ring after being arranged in the slot, so that external dust and impurities are prevented from entering the interior of the bearing outer ring.
