Abstract
The utility model provides a double-row wedged brake retainer, comprising two retainer roll rings, wherein the two roll rings are distributed in a side-by-side manner; and the two roll rings are fixedly connected by a ring-shaped spacing ring. The double-row wedged brake retainer has the beneficial effects that since a form of distribution of double-row rolls is adopted, larger bearing torque can be provided, so that the appearance size of a low-speed contact brake can be more compact, and the size for a connecting shaft can also be small as much as possible.
Description
Technical field
The utility model belongs to contact type non-return device field, especially relates to the retainer that uses in a kind of non-return device.
Background technique
Non-return device is widely used in belt conveyor, noria, scraper conveyor, blower fan, rotary kiln and other need prevent that drive system from possibly cause the occasion of counter-rotating because the load sliding force drives.The contact type non-return device is applied to the lower velocity shaft of drive system.
General contact type non-return device mainly is made up of the retainer between inner ring, outer ring and the Internal and external cycle, and retainer is generally single roller circle, and retainer roller circle is provided with a plurality of rollers that are used to locate; Be furnished with the wedge-like special-shaped block between the roller, each special-shaped block all is furnished with torque spring, when inner ring is rotated in the forward; Special-shaped block just contacts with inside and outside circle gently, and when the inner ring counterrotating, special-shaped block is under the effect of spring force; Drive special-shaped block deflection,, thereby bear check moment the Internal and external cycle wedging.
Existing retainer all is a single structure, promptly has only a retainer roller circle, because under identical check moment requires; There is the little shortcoming of the surface of contact gross area; Under the roller piece and check piece situation that use same material, length that can only be through increase roller piece and check piece (still consider the rigidity and the mechanical property of roller piece and check piece itself, this length also is can not unconfined increase); The sectional dimension that perhaps increases roller piece and check piece realizes bearing the performance of heavy duty; Exist the requirement of passing shaft diameter bigger, the volume of entire equipment increases, the problem that weight of equipment uprises.
Summary of the invention
The problem that the utility model will solve provides and is a kind ofly keeping reducing the non-return device profile under the situation of same size, and weight reduction reduces the non-return device retainer of the transmission shaft diameter of axle.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of double non-return device retainer that agrees with, comprise two retainer roller circles, and two roller circles distribute side by side, and the spacer ring through a ring-type between the two roller circles is fixedly connected.
Further, the middle bump that also is provided with a circle to outer lug in said spacer ring outer ring.
Further, said bump is provided with a plurality of axial axis holes.
Advantage and the good effect that the utlity model has are: adopt the form of biserial roller arrays that bigger bearing torque can be provided; Thereby make that the boundary dimension of low speed contact non-return device can be compact more; Size for coupling shaft also can be as much as possible little, and then reduced the volume and weight of equipment.

Fig. 3 is the schematic perspective view of spacer ring
Among the figure:
1, retainer roller circle 2, spacer ring 3, bump
4, axis hole 5, roller 6, special-shaped block
Embodiment
Fixing and the layout of special-shaped block is the crucial part in the whole non-return device design, and as shown in the figure, the non-return device retainer of the utility model adopts the double body split-type structural that agrees with; Promptly by two the retainer roller circles 1 side by side in the outside; One integrated type spacer ring 2 is arranged between the two roller circles, and the spacer ring outer ring also is provided with a bump 3 to outer lug, is used for better separating two groups of roller circles; Simultaneously can guarantee that non-return device is in time under axial vertically arranged situation; This structure possesses enough intensity, can not cause failure of apparatus because of this device of weight conquassation of roller chunk self.A plurality of axis holes that axial direction on the bump is opened can be used for holding the running shaft of roller and special-shaped block, make space utilization compact and reasonable more.
Simultaneously owing to adopt the form of biserial roller arrays that bigger bearing torque can be provided, thereby make that the boundary dimension of low speed contact non-return device can be compact more, also can be as much as possible little for the size of coupling shaft.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (3)
1. double non-return device retainer that agrees with, it is characterized in that: comprise two retainer roller circles (1), two roller circles distribute side by side, and the spacer ring (2) through a ring-type between the two roller circles is fixedly connected.
