Abstract
The utility model relates to a thrust angular contact ball bearing for the novel automobile steering device, comprising an inner ring, an outer ring and steel balls. The utility model is characterized in that the steel ball is located on the center ball race of the inner ring; the cross section of the outer ring is in L shape; a stop ring is embedded on the L shape corner of the inner side, which is opposite to the outer ring, of the steel ball, and on the upper end face of the L shape on the inner side of the outer ring; and the space between the inner ring and the outer ring is filled with steel balls. The utility model has the advantages that because automobile steering device is improved with the thrust angular contact ball bearing, the inner ring, the outer ring, and the stop ring is arranged, the disassembly of the rings and the steel balls can be prevented; the interference can be prevented when the bearing is pressed and loaded; the problem that the balls are lacked after the balls are disassembled which can influence the service life of the bearing can be completely solved; at the same time, the installation quality can be ensured and the assembly efficiency of the main plants can be improved.
Description
Technical field
The utility model relates to a kind of angular contact ball bearing, particularly a kind of novel automobile steering device angular contact thrust ball bearing.
Background technique
Automobile steering device is that the rotation with steering wheel becomes the swing of pitman arm or the straight reciprocating motion of rack shaft, and the mechanism that handling maneuver power is amplified.Present automobile steering device angular contact thrust ball bearing (Fig. 1), inside is the full ball assembling structure of no retainer, by an inner ring and an outer ring steel ball is clamped, mainly be subjected to axial force to carry out work, between steel ball, the inside and outside circle three chainless (sequence of sanqu songs within a particular musical mode structure), the advantage of this class formation is that the processing of bearing is fairly simple.But also exist following drawback: because automobile steering device is lower with the angular contact thrust ball bearing rotating speed, bearing load is bigger, particularly when installation, require to lack ball, this kind structure inside and outside circle when installation is very easily separated, the steel ball ratio is easier to dissipate, in case lack ball and the supporting automobile steering device angular contact thrust ball bearing of main frame, just do not reach 300000 requirements fatigue life, this kind structural design efficiency of installing software is also relatively lower in addition.
Summary of the invention
The purpose of this utility model is to solve automobile steering device of the prior art with the existing the problems referred to above of angular contact thrust ball bearing, and a kind of novel automobile steering device angular contact thrust ball bearing is provided.The utility model designs a kind of novel automobile steering device angular contact thrust ball bearing, comprise inner ring, outer ring, steel ball, it is characterized in that: steel ball is positioned on the central raceway of inner ring, the cross section of outer ring is L-shaped, steel ball is with respect to the L shaped knuckle place on the inner side surface of outer ring, is embedded with stop ring on the L shaped upper-end surface of the inner side surface of outer ring.Fill up steel ball between inner ring and the outer ring.The utility model has the advantages that, use the inside and outside coil structures of angular contact thrust ball bearing and an end stop ring is installed by transforming automobile steering device, stop the lasso and the steel ball sequence of sanqu songs within a particular musical mode, and when loading, shaft strength do not have interference, thoroughly solve and lack ball impact bearing working life behind the ball that looses, guaranteed the installation quality simultaneously again and improved the efficiency of assembling of main engine factory.
Description of drawings
Accompanying drawing 1 is the prior art constructions schematic representation,
Accompanying drawing 2 is a structural representation of the present utility model,
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
Comprise inner ring 1, outer ring 2, steel ball 3 among the figure, it is characterized in that: steel ball 3 is positioned on the central raceway 4 of inner ring 1, the cross section of outer ring 2 is L-shaped, and steel ball 3 is with respect to the L shaped knuckle place on the inner side surface of outer ring 2, is embedded with stop ring 5 on the L shaped upper-end surface of the inner side surface of outer ring 2.Fill up steel ball 3 between inner ring 1 and the outer ring 2.
Owing on the L shaped upper-end surface of the inner side surface of outer ring 2, be embedded with stop ring 5, can prevent that therefore steel ball 3 from coming off from the upper-end surface, thereby guarantee not falling apart of inner ring 1, outer ring 2, steel ball 3 threes.And be installed in vehicle turn on the assembly time, the 5 pairs of shaft strengths of stop ring load and have no effect.Can satisfy requirement to bogie of car.
Claims (2)
1, a kind of novel automobile steering device angular contact thrust ball bearing, comprise inner ring, outer ring, steel ball, it is characterized in that: steel ball is positioned on the central raceway of inner ring, the cross section of outer ring is L-shaped, steel ball is with respect to the L shaped knuckle place on the inner side surface of outer ring, is embedded with stop ring on the L shaped upper-end surface of the inner side surface of outer ring.
2, by the described automobile steering device angular contact thrust ball bearing of claim 1, it is characterized in that: fill up steel ball between inner ring and the outer ring.
