Abstract
The utility model discloses a high-precision bearing. The high-precision bearing comprises an outer ring of the bearing, an inner ring of the bearing, rolling bodies and dustproof covers, wherein grooves corresponding to the rolling bodies are respectively formed in the center parts of the inner surface of the outer ring and the outer surface of the inner ring; the rolling bodies are clamped in the grooves; clamping slots are formed in the two sides (close to the edges) of the groove of the outer ring; the dustproof covers are arranged in the clamping slots; straining rings with gaps are further arranged in the clamping slots and above the dustproof covers and correspond to the dustproof covers in a complementing manner; two half keeping frames are respectively installed on the two sides of the rolling body; and a rivet is arranged on the half keeping frame on one side of the rolling body and is riveted with a rivet hole in the half keeping frame on the other side of the rolling body to form a whole body. The bearing has a good dustproof effect, components are compactly connected with one another, and a rolling steel ball is firmly fixed.
Description
Technical field
The utility model relates to a kind of high-precision bearing.
Background technique
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course, also can say, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process, develop into now, the kind of bearing is varied, precision bearing is also more and more, but existing precision bearing dust-proof effect is poor, and the bearing component connect not compact, and bearing element spare is fixing not firm.
The model utility content
This practical technical problem to be solved provides a kind of high-precision bearing, this bearing good dustproof effect, and parts connect compact, and rolling steel balls is fixed.
In order to solve existing technical problem the technical solution adopted in the utility model be: a kind of high-precision bearing, comprise bearing outer ring, bearing inner race, rolling element and dust cover, the center portion of described inner surface and inner ring outer surface is respectively equipped with and the corresponding groove of described rolling element, described rolling element is stuck in this groove, the groove both sides of described outer ring are provided with draw-in groove near its edge, described dust cover is located in this draw-in groove, it is characterized in that, also be provided with the collar with a breach in the described draw-in groove, this collar be arranged on the described dust cover and with the form responding setting of described dust cover with complementation, described rolling element both sides are separately installed with two and half retainers, half retainer in described rolling element one side is provided with rivet, and this rivet is riveted with the riveted holes on opposite side half retainer and is connected.
Above-mentioned a kind of high-precision bearing is characterized in that, described bearing outer ring internal surface, bearing inner race outer surface, half retainer place all scribble oil layer.
Above-mentioned a kind of high-precision bearing bearing is characterized in that described rolling element is preferably steel ball.
Above-mentioned a kind of high-precision bearing bearing is characterized in that, between described dust cover and the described draw-in groove spring ring is installed.

Embodiment
As shown in Figure 1 and Figure 2, a kind of high-precision bearing, comprise bearing outer ring 1, bearing inner race 2, rolling element 3 and dust cover 4, the center portion of outer ring 1 internal surface and inner ring 2 outer surfaces is respectively equipped with and the corresponding groove 5 of described rolling element, rolling element 3 is stuck in this groove 5, as further improvement of the utility model, rolling element 3 is preferably steel ball; Groove 5 both sides of outer ring 1 are provided with draw-in groove 6 near its edge, and dust cover 4 is located in this draw-in groove 6, between dust cover 4 and the draw-in groove 6 spring ring 9 is installed, and this spring ring 9 connects the outside face of dust cover 4 internal surfaces and inner ring 2, has played the effect of vibration reduction and cushioning.
In Fig. 2, also be provided with the collar 8 with a breach in the draw-in groove 6, this collar 8 be arranged on the dust cover 4 and with the form responding setting of dust cover with complementation, the effect of firm dust cover 4 has been played in this collar 8, and dust cover 4 is stuck in the draw-in groove 6 firmly; Be separately installed with two and half retainers 7 and 10 in rolling element 3 both sides, be provided with rivet at half retainer 7 of rolling element one side, the riveted holes riveted joint on rivet and opposite side half retainer and being connected, two retainers are connected by riveted joint, sound construction.
For make this bearing in the running friction factor reach minimum, all scribble oil layer at bearing outer ring 1 internal surface, bearing inner race 2 outer surfaces, half retainer, 7 places.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and the specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in the claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
