Abstract

The utility model discloses a four-point contact ball bearing with special structure, which mainly comprises an outer ring (1), a rivet (2), an inner ring (3), a steel ball (4), a retainer (5) and a closing ring (6), wherein the steel ball (4) and the retainer (5) are riveted through the rivet to form a component, the component can form a whole bearing after covering with the outer ring (1) and the inner ring (3), and the matching closing ring (6) is installed on the outer ring (1). The four-point contact ball bearing has the beneficial effects that the bearing can bear the axial loads at the two directions, and an inner roll path and an outer roll path are both of integrated structures, the bearing capability is strong, the rigidity is large, and the rotational velocity is high and stable.

Description

A kind of special structure four-point contact ball bearing
Technical field
The utility model relates to the ball bearing processing technique field, relates in particular to a kind of special structure four-point contact ball bearing.
Background technique
At present, mostly the bearing that is widely used on the equipment such as lathe, rolling mill roll, large truck diesel engine gear-box is deep groove ball bearing, angular contact ball bearing and four-point contact ball, in actual conditions uses, because the defective of structure, shortened bearing working life.And supporting main frame installing space is limited, and the bearing of design should satisfy the working condition of main frame, also requires bearing life long, and existing bearing can't satisfy these requirements.
The model utility content
The purpose of this utility model provides a kind of special structure four-point contact ball bearing, and its bearing capacity is strong, and rigidity is big, and rotating speed is high and steady.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of special structure four-point contact ball bearing, mainly form by outer ring, rivet, inner ring, steel ball and retainer, steel ball becomes assembly with retainer by closing-up, this assembly and outer ring, inner ring trap constitute solid bearing, the raceway of outer ring and inner ring is peach shape ditch, each raceway groove and steel ball have two point of contact, and wrapping angle is 30 °; Supporting stop ring is installed on described outer ring.
The beneficial effects of the utility model are: this bearing can bear the axial load of both direction, and the Internal and external cycle raceway is overall structure, and bearing capacity is strong, and rigidity is big, and rotating speed is high and steady.
Description of drawings
Fig. 1 is the structural representation of the utility model special structure four-point contact ball bearing.
Fig. 2 is an outer ring raceway structural representation of the present utility model.
Fig. 3 is an inner ring raceway structural representation of the present utility model.
Among the figure: 1, outer ring, 2, rivet, 3, inner ring, 4, steel ball, 5, retainer, 6, stop ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is done description in further detail:
As shown in Figure 1, special structure four-point contact ball bearing of the present utility model, mainly form by outer ring 1, rivet 2, inner ring 3, steel ball 4, retainer 5 and stop ring 6, steel ball 4 becomes assembly with retainer 5 by rivet 2 riveteds, this assembly and outer ring 1, inner ring 3 traps constitute solid bearing, the raceway of outer ring 1 and inner ring 3 is peach shape ditch, and each raceway groove and steel ball 4 have two point of contact, and wrapping angle is 30 °; Stop ring 6 is installed in supporting use on the outer ring 1.
Special construction angular contact ball bearing of the present utility model can bear the occasion that radial load and axial load act on simultaneously, also can bear the axial load of pure radial load and either direction, has the high performance of limit speed, be fit to the occasion that runs up, be widely used on the machinery such as lathe, rolling mill roll, large truck diesel engine gear-box.
Compare with existing zanjon gutter shape raceway, outer ring 1 and the inner ring 3 of the utility model ball bearing are The peach-shaped cross section because the Internal and external cycle channel design of bearing is special, makes each raceway groove and steel ball 4 have two to contact Point, contact angle are 30 °, thereby can bear the axial load of both direction. With existing four-point contact ball Bearing double semi outer rings or two half inner ring are compared, and the Internal and external cycle raceway of the utility model structure is overall structure, So bearing capacity is stronger, rigidity is bigger, and rotating speed is higher more steady.
The research and development sky of this types of bearings of China has been filled up in the successful development of special structure four-point contact ball bearing In vain, strengthened the product competitiveness of our company; Compare deep groove ball bearing, angular contact ball bearing, 4 contacts Ball bearing, load have improved 30%, Service life 3 times, and reliability height, stability are strong.
