Abstract
The utility model discloses an automobile hub bearing. The automobile hub bearing comprises a bearing outer ring, a bearing inner ring and steel balls, wherein the steel balls are arranged between the bearing outer ring and the bearing inner ring; the bearing inner ring consists of two half inner rings which are symmetrically arranged; elastic grooves are formed in the end faces of the half inner rings; elastic hooks are respectively arranged at the two ends of each connecting sheet; the two half inner rings are fixed through pressing the elastic hooks into the elastic grooves. According to the automobile hub bearing, the two half inner rings are fixed through pressing the elastic hooks into the elastic grooves, and the half inner rings and the connecting sheets form an integer, so that the reliability of half inner ring connection of the bearing is guaranteed effectively; during assembly, the connecting sheets serve as assisting tools for assembly, so that the steel ball assembly speed is increased greatly, the overlapping of two rows of steel balls can be prevented effectively, and the assembly quality of the bearing is improved.
Description
Technical field
The utility model relates to a kind of bearing, relates in particular to a kind of automobile hub bearing.
Background technique
The Main Function of automobile hub bearing is load-bearing and provides accurate guiding for the rotation of wheel hub.Connection between conventional automobile hub bearing half inner ring is general adopt in ring recess with the retainer fore shaft, be connected, or the bear inner ring grooved railway fore shaft is pressed into the steel ball connection, these two kinds of Placements all are not suitable with the automobile hub bearing without retainer; If but, without connecting sheet, the assembling of bearing, installation, Department of Transportation can't carry out.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of automobile hub bearing is provided, and has not only guaranteed the reliability and stability of bearing inner race, and has improved assembly quality and the efficiency of assembling of bearing.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of automobile hub bearing, comprise bearing outer ring, bearing inner race and be arranged on bearing outer ring and bearing inner race between steel ball, described bearing inner race is comprised of two symmetrically arranged half inner rings, be provided with elastic groove on the end face of described half inner ring, the connecting sheet two ends are respectively arranged with elastic hook, and elastic hook is pressed in elastic groove fixes two and half inner rings.
The beneficial effect the utlity model has: be pressed in elastic groove and fix two and half inner rings by elastic hook, make half inner ring and connecting sheet form one, effectively guaranteed that bearing connects the reliability of half inner ring; In when assembling, the assistant tool of connecting sheet during as assembling, improved the speed of assembling steel ball greatly, and effectively square box two is arranged the overlapping of steel balls, has improved the assembly quality of bearing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: bearing outer ring 1, bearing inner race 2, steel ball 3, half inner ring 4, connecting sheet 5, elastic groove 6, elastic hook 7.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, a kind of automobile hub bearing, comprise bearing outer ring 1, bearing inner race 2 and be arranged on bearing outer ring 1 and bearing inner race 2 between steel ball 3, described bearing inner race 2 is comprised of two symmetrically arranged plate inner rings 4, be provided with elastic groove 6 on the end face of described half inner ring 4, connecting sheet 5 two ends are respectively arranged with elastic hook 7, and elastic hook 7 is pressed into interior two and half inner rings 4 of fixing of elastic groove 6.
During the utility model assembling, by External Force Acting, the elastic hook 7 on connecting sheet 5 is pressed in the elastic groove 6 of half inner ring 4 end faces, makes connecting sheet 5 and half inner ring 4 form one, guaranteed the stability of bearing inner race 2; During assembling steel ball 3, after the first row steel ball of packing into, be pressed into connecting sheet 5, using connecting sheet 5 as the assembling pad, the second row steel ball is taken advantage of a situation and fall within another raceway groove of bearing outer ring 1, greatly improve the assembling speed of steel ball 3, can also effectively prevent the overlapping of two row's steel balls 3, improved the assembly quality of bearing.
