Abstract
The utility model discloses a bearing with a fixed dustproof cover. The bearing comprises a bearing outer ring, a bearing inner ring, a plurality of rolling bodies and a first holder, wherein the bearing outer ring is sleeved outside the bearing inner ring, guide rail grooves for placing the rolling body are formed in opposite circumferential surfaces of the bearing outer ring and the bearing inner ring, and the first holder is sleeved on the rolling body. The bearing further comprises a dustproof cover and a second holder, wherein slots are formed in two sides of the guide rail grooves, the dustproof cover is clamped in the slots, a lock opening is formed in the edge of the dustproof cover, a fixing device extending into the slots and being clamped with the lock opening is arranged on the inner side wall of the bearing outer ring, and the second holder is sleeved on one side of the rolling body and is vertical to the first holder. The fixing device arranged on the bearing outer ring of the bearing plays a role in fixing the dustproof cover, the dustproof cover can not drop off due to long-term use, and one half holder arranged in the bearing further plays a role in keeping the position of a steel ball fixed.
Description
Technical field
The utility model relates to a kind of bearing, and is especially a kind of with the fixing bearing of dust cover.
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.Mostly dust cover on the existing bearing is to be fastened in the draw-in groove on the bearing, the fixing device of dust cover not on the bearing, and in the course of time, dust cover can come off, and dust, foreign material will be fallen into the normal operation that affects bearing in the bearing inner race; Inner many of the steel balls of existing bearing are provided with a retainer keeping the fixing of steel ball position, and when the load of bearing when bearing was excessive, the effect of a retainer just can't be protected, and is prone to accident in the using process of bearing.
The model utility content
The purpose of this utility model is in order to solve the existing defective of prior art middle (center) bearing, to provide a kind of dust cover firm, with the novel bearing of two retainers.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of with the fixing bearing of dust cover, comprise bearing outer ring, bearing inner race, a plurality of rolling elements and the first retainer, described bearing outer ring is sleeved on the outside of bearing inner race, the opposed side face of bearing outer ring and bearing inner race is provided with the guide-track groove of settling described rolling element, described the first retainer is sleeved on the rolling element, as improvement of the present utility model, described bearing also comprises dust cover and the second retainer, the both sides of described guide-track groove are provided with draw-in groove, described dust cover is fastened in this draw-in groove, the edge of dust cover is provided with fore shaft, and the madial wall of described bearing outer ring is provided with and extend into the fixing device that draw-in groove is interior and described fore shaft is stuck; Described the second retainer is enclosed within a side of rolling element and vertical with described the first retainer.
Above-mentioned a kind of with the fixing bearing of dust cover, the second retainer is half retainer.
Above-mentioned a kind of with the fixing bearing of dust cover, described fixing device and described bearing outer ring are integral.
Above-mentioned a kind of with the fixing bearing of dust cover, described fixing device is an annular convex of extending to bearing inner race vertically from described bearing outer ring madial wall.
Above-mentioned a kind of with the fixing bearing of dust cover, described dust cover is along circumferentially extending.
Above-mentioned a kind of with the fixing bearing of dust cover, described rolling element is steel ball.
The beneficial effects of the utility model are: the bearing outer ring of this bearing is provided with fixing device, dust cover has been played fixation, dust cover can not come off because of long-time the use, also is provided with one and half retainers in the bearing, with fixing of further maintenance steel ball position.
Description of drawings
Fig. 1 is structural representation of the present utility model
Embodiment
Further understand and be familiar with for making structure characteristic of the present utility model and the effect reached had, cooperate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1, a kind of with the fixing bearing of dust cover, comprise bearing outer ring 1, bearing inner race 2, a plurality of rolling elements 3 and the first retainer 4, bearing outer ring 1 is sleeved on the outside of bearing inner race 2, bearing outer ring 1 is provided with the guide-track groove 5 of settling rolling element 3 with the opposed side face of bearing inner race 2, the first retainer 4 is sleeved on the rolling element 3, as improvement of the present utility model, bearing also comprises dust cover 6 and the second retainer 7, the both sides of guide-track groove 5 are provided with draw-in groove 8, dust cover 6 is fastened in this draw-in groove 8, and the edge of dust cover 6 is provided with fore shaft 9, and the madial wall of bearing outer ring 1 is provided with and extend in the draw-in groove 8 fixing device 10 stuck with fore shaft 9; The second retainer 7 is enclosed within a side of rolling element 3 and vertical with the first retainer 4.
In the utility model, the second retainer 7 is half retainer, and rolling element 3 is preferably steel ball, this half retainer is mutually vertical with the first retainer 4, with the control steel ball radially and move axially, and in fixing position, rotate, so that the maintenance of steel ball is more firm.
Further improve as the utility model, fixing device 10 is integral with bearing outer ring 1, dust cover 6 is along circumferentially extending, fixing device 10 is an annular convex of extending to bearing inner race 2 vertically from bearing outer ring 1 madial wall, the fore shaft 9 at this annular convex and dust cover 6 edges is mutually stuck, in bearing high load and high-revolving situation, dust cover 6 can not come off from bearing body, can not cause dust, foreign material are fallen into affects bearing in the bearing inner race normal operation.
More than show 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.
