Description

A kind of bearing

Technical field

The utility model relates to field of bearings more particularly to a kind of bearings that can be realized antiskid function.

Background technique

Bearing is that component that is fixed and reducing load coefficient of friction is played in mechanical transmission course, it may also be said to, when other Parts are when generating relative motion each other on axis, for reducing coefficient of friction and the holding shaft center in power transmission process Fixed parts.Bearing is a kind of very important components in contemporary mechanical equipment, its major function is the mechanical rotation of support Swivel, to reduce mechanical load coefficient of friction of the equipment in transmission process.

Bearing needs to be installed in mounting base in use, the bearing installed at present be all using mounting base and Bearing is stuck in mounting base by the extruding force between bearing, but will appear the feelings of displacement in bearing long-time use process Condition；Bearing will appear vibration, after prolonged use bearing and mounting base due to directly contacting with mounting base in use Gap can become larger, shake more violent, and with noise, such case lower bearing can be also easily damaged.

Utility model content

The purpose of this utility model is that overcoming the drawbacks described above of the prior art, a kind of bearing is provided.

To achieve the above object, the technical scheme that the utility model is provided is as follows: a kind of bearing, including bearing outer ring, axis Inner ring, retainer, bearing mounting base and several rolling elements are held, rolling element is installed on retainer and is set to bearing outer ring and bearing Between inner ring, bearing outer ring is arranged in bearing mounting base, and bearing outer ring left-hand end and right-hand end are respectively along bearing outer ring circumference Face is convexly equipped with ring rib for one week, and bearing outer ring rule between the ring rib of two sides is equipped with zigzag raised line.

Further, zigzag raised line is in the connection that joins end to end.

Further, ring rib setting height is higher than zigzag raised line.

Further, zigzag raised line cross-sectional shape includes arc, ellipse and semicircle.

Further, at bearing mounting base and bearing outer ring connecting pin corresponding shaft bearing outer ring ring rib and zigzag raised line It is recessed with annular groove and zigzag groove respectively inwards.

The benificial effect of the utility model is to structure is simple, it can prevent bearing outer ring after connecting with bearing mounting base The offset phenomena of generation, connection more fasten, effectively extend the service life of bearing, should be widely promoted.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of bearing of the utility model；

Fig. 2 is a kind of schematic elevation view of bearing of the utility model.

Specific embodiment

With reference to the accompanying drawing and preferred embodiment is further described with regard to the technical solution of the utility model.

As Figure 1-Figure 2, a kind of bearing described in the utility model, including bearing outer ring 1, bearing inner race 2, retainer 3, bearing mounting base (not shown) and several rolling elements 4, rolling element 4 be installed on retainer 3 and be set to bearing outer ring 1 with Between bearing inner race 2, bearing outer ring 1 is arranged in bearing mounting base, and 1 left-hand end of bearing outer ring and right-hand end are respectively outside bearing It encloses 1 periphery and is convexly equipped within one week ring rib 5, the rule between two sides ring rib 5 of bearing outer ring 1 is equipped with zigzag raised line 6。

Further, zigzag raised line 6 is in the connection that joins end to end.

Further, the setting of ring rib 5 height is higher than zigzag raised line 6.

Further, 6 cross-sectional shape of zigzag raised line includes arc, ellipse and semicircle.

Further, bearing mounting base and 1 connecting pin corresponding shaft bearing outer ring of bearing outer ring, 1 ring rib 5 and zigzag are convex Annular groove (not shown) and zigzag groove (not shown) are concaved at item 6 respectively.

More than, the utility model structure is simple, due to the zigzag raised line 6 and ring rib being arranged on bearing outer ring 1 5, and at bearing mounting base zigzag raised line 6 corresponding with 1 connecting pin of bearing outer ring and ring rib 5 be arranged zigzag groove and Annular groove prevents bearing from connecting with bearing mounting base so that bearing, when being clamped with bearing mounting base, connection more fastens After generate offset phenomena, the setting of zigzag raised line 6 increases the contact area with bearing mounting base, and the bearing outer ring 1 made exists It with uniform force when working after bearing mounting base clamping, is hardly damaged, effectively extends the service life of bearing, be worth pushing away extensively Extensively.

Above-described is only the principles of the present invention and preferred embodiment.It should be pointed out that the common skill of this field For art personnel, without departing from the principle of this utility model, moreover it is possible to make several variations and modifications, also should be regarded as belonging to In the protection scope of the utility model.
