Abstract
The utility model discloses a unilateral bearing, which belongs to machinery accessories. An existing unilateral bearing with a spring piece is low in assembling efficiency. The unilateral bearing comprises an inner ring, a first outer ring and a second outer ring, wherein the first outer ring and the second outer ring are parallelly arranged on the outer side of the inner ring. A plurality of steel balls are retained between the first outer ring and the inner ring through a first retainer, and a plurality of rollers are retained between the second outer ring and the inner ring through a second retainer. The unilateral bearing is characterized in that a plurality of elastic structures which are in one-to-one corresponding with the rollers and exert elastic force on the corresponding rollers are arranged on the second retainer, and the elastic force exerted on the corresponding rollers by the elastic structures is uniform in direction. The functions of the spring piece are designed on the retainers, and the spring piece is formed together with the retainer so that the assembly of the spring piece is eliminated during the assembly of the bearing, accordingly a complex procedure is eliminated and the assembling efficiency can be greatly improved.
Description
Technical field
The utility model belongs to mechanical fitting, specifically is a kind of unilateral bearing and the retainer that is used for this bearing.
Background technique
In unilateral bearing (referring to Fig. 8), establish spring sheet 11 between retainer 06 (referring to Fig. 5-7) and the roller 07 and reach the three and closely cooperate,, unilateral bearing rely on spring sheet the elastic force effect of roller to be guaranteed the one-way only operation of bearing when turning round.But the unilateral bearing of this structure will shoot reed one by one when assembling, if spring sheet is too tight, assembling is effort too; If spring sheet is pine too, drop easily, efficiency of assembling is too low to be a bottleneck of unilateral bearing always.
The model utility content
The technical problem that the utility model will solve and the technical assignment of proposition are to overcome to have now to have the too low defective of unilateral bearing efficiency of assembling of spring sheet, and a kind of unilateral bearing and retainer are provided.
For reaching the purpose of the utility model; The unilateral bearing of the utility model comprises an inner ring, first outer ring and second outer ring that is positioned at the said inner ring outside arranged side by side; Maintain plurality of steel balls by one first retainer between said first outer ring and the described inner ring; Maintain several rollers by one second retainer between said second outer ring and the described inner ring; It is characterized in that: several are set on described second retainer one to one elastic force are applied to the elastic structure on the corresponding roller, and the elastic force direction that each elastic structure is applied on the corresponding roller is consistent with described roller.
As the optimization technique measure of the utility model unilateral bearing, described elastic structure is made into integration by the same material and second retainer of said second retainer.Perhaps, described elastic structure by the foreign material of said second retainer with second retainer built in.
For reaching the purpose of the utility model, the retainer of the utility model is to be provided with several holding positions above that, it is characterized in that: each described holding position is provided with elastic structure, and the elastic force direction of each elastic structure is consistent.
As the optimization technique measure of the utility model retainer, described elastic structure is made into integration by the same material and the retainer of said retainer.Perhaps described elastic structure by the foreign material of said retainer with retainer built in.
The beneficial effect of the utility model is: the design of spring sheet function on retainer, is processed with retainer, during running in bearings, lacked the assembling of spring sheet, just lacked loaded down with trivial details operation one, improved efficiency of assembling greatly.

Embodiment
Below in conjunction with Figure of description the utility model is further specified.
The unilateral bearing of the utility model; As shown in Figure 4; Comprise inner ring 01, first outer ring 02 that is positioned at inner ring 01 outside and second outer ring 03 arranged side by side; Keep plurality of steel balls 05 by first retainer 04 between first outer ring 02 and the inner ring 01; Between second outer ring 03 and the inner ring 01 by second retainer 06 keep being provided with on several roller 07, the second retainers 06 several with roller one to one with elastic force be applied to elastic structure 08 on the corresponding roller (concrete, establish several and roller holding position 09 one to one on second retainer 06; Each holding position 09 is established elastic structure 08), and each elastic structure 08 is applied to the elastic force direction consistent (direction like this elastic force is identical with the big hot angle of tangent direction of this elastic structure position) on the corresponding roller.Inner in order to guarantee that sealing stops extraneous dust etc. to get into bearing, between the two ends of inner ring and corresponding outer ring, be equipped with seal ring 10.
