Abstract

The utility model discloses a novel asymmetric V -arrangement inner circle bearing arrangement, it is constituteed including bearing inner race (1), rolling element steel ball (2), holder (3), bearing inner race (4), oil storage area (5), the raceway is the arc in the outer lane, the outer raceway of inner circle is left -right asymmetry V shape, rolling element steel ball (2) are between arc outer lane (1) and asymmetric V -arrangement inner circle (4), it is fixed by holder (3), constitute oil storage area between asymmetric V -arrangement inner circle (4) and rolling element steel ball (2). The outer raceway V -arrangement structure both sides inclination of inner circle is different, and asymmetric V -arrangement raceway makes the steel ball roll soon producing the sideway in the raceway revolution, has realized in the bearing working process complete surperficial uniform contact between steel ball and raceway, has reduced steel ball single -point contact number of cycles, and the steel ball of having avoided traditional bearing to lead to the fact in the use is banded wearing and tearing, has reduced the steel ball wear rate, has reduced local temperature rise, has lengthened life.

Description

A kind of novel Asymmetric V-type inner-ring bearing structure
Technical field
This utility model relates to field of mechanical structure design, particularly relates to a kind of Novel bearing structure.
Background technology
Bearing is a kind of important parts in plant equipment in the present age, primarily serve support, bear the effect of load, along with the raising of industrialization degree, the application of bearing is more extensive, and this is accomplished by that the aspect such as bearing load carrying capacity and service life is had higher requirement.In traditional bearing structure, rolling element steel ball the most typically can occur fretting wear, and in uneven zonal distribution, affects steel ball service life.The utility model discloses a kind of novel bearing arrangement, being mainly characterized by Internal and external cycle is disunity structure, makes rolling element steel ball can realize full unfolded surface, and full surface can be occurred to contact when bearing working.Leave reserve between inner ring and rolling element steel ball, provide good lubricant effect for steel ball, reduce temperature rise simultaneously, greatly strengthen the service life of steel ball.
Summary of the invention
The purpose of this utility model is: in order to overcome above-mentioned the deficiencies in the prior art, and this utility model provides and a kind of rolling element steel ball can be made to carry out the contact of full surface the Novel bearing structure increased the service life.
This utility model be the technical scheme is that a kind of novel Asymmetric V-type inner-ring bearing structure, its composition includes bearing outer ring, rolling element steel ball, retainer, bearing inner race, reserve, it is characterized in that: in described bearing outer ring, raceway is circular arc, having a bit of smooth place at arc top, smooth place contacts with steel ball;The outer raceway of described bearing inner race is left-right asymmetry V-arrangement;Described rolling element steel ball can rollably be arranged in circular arc bearing outer ring between raceway and the outer raceway of Asymmetric V-type bearing inner race;It is outer between raceway and rolling element steel ball that described reserve is arranged at bearing inner race;Described bearing inner race is Asymmetric V-type structure, and Jiao Hejiao is unequal, Asymmetric V-type structure both sides angleαWithα´、βWithβRespectively about bearing centre axial symmetry;Leaving reserve between described Asymmetric V-type bearing inner race and rolling element steel ball, rolling element steel ball can dispel the heat in time and lubricate.
The beneficial effects of the utility model are that of avoiding the fretting wear that local in use occurs as the steel ball of important spare part in bearing.This utility model improves bearing internal external coil structures, enables rolling element steel ball to occur full surface to contact;The inconsistent new structure of this not Internal and external cycle too increases the bearing capacity of bearing, and then extends the service life of bearing.
Accompanying drawing explanation
Fig. 1 is described bearing left view.
Fig. 2 is the structural representation of described novel bearing.
Fig. 3 is partial enlarged drawing at A in Fig. 2.
Fig. 4 is partial enlarged drawing at B in Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
If Fig. 2 is a kind of novel Asymmetric V-type inner-ring bearing structural representation, it is made up of bearing outer ring, bearing inner race, rolling element, retainer and reserve.
As shown in Figure 3 and Figure 4, including bearing outer ring (1), rolling element steel ball (2), retainer (3), bearing inner race (4) and reserve (5).Described bearing outer ring (1) profile is arc, has a bit of smooth place at arc top, and smooth place contacts with steel ball, and bearing inner race (4) profile is asymmetric V-arrangement, i.e.α, βAngle is unequal, Asymmetric V-type structure both sides angleαWithα´、βWithβRespectively about bearing centre axial symmetry.Its two side walls contacts with steel ball, owing to bearing inner race uses Asymmetric V-type structure, steel ball rotary roll motion between Internal and external cycle makes steel ball that the contact of full surface occur, steel ball can be able to fully deployed, compared with traditional bearing, considerably increase friction area, it is to avoid steel ball is banding abrasion, extend steel ball service life, and then extend the service life of bearing;Simultaneously as bearing uses Asymmetric V-type structure, it is also possible to strengthen the bearing capacity of bearing.
As it is shown on figure 3, leave certain gap between Asymmetric V-type bearing inner race (4) and rolling element steel ball (2), can preferably store lubricating oil, improve the lubricant effect of bearing, reduce temperature rise.In steel ball rotation process, it is possible not only to realize the uniform lubrication of whole spherome surface, and drive oil lubrication whole Bearing inner structure can be rotated by steel ball, improve bearing lubrication condition, the noise produced during reducing bearing operation, it is ensured that bearing is efficient operation under High Quality Environment.

Claims (3)

1. a novel Asymmetric V-type inner-ring bearing structure, its composition includes bearing outer ring (1), rolling element steel ball (2), retainer (3), bearing inner race (4), reserve (5), it is characterized in that: described bearing outer ring (1) interior raceway is circular arc, having a bit of smooth place at arc top, smooth place contacts with steel ball;Described rolling element steel ball (2) can rollably be arranged between circular arc bearing outer ring (1) interior raceway and Asymmetric V-type bearing inner race (4) outer raceway;Described bearing inner race (4) outer raceway is left-right asymmetry V-arrangement;Described reserve (5) is arranged between bearing inner race (4) outer raceway and rolling element steel ball (2).
