Abstract
The utility model relates to a support roller exclusive used holdback of a belt conveyer, which solves the problems of the prior support rollers of short longevity, big noise and great resistance. The support roller exclusive used holdback comprises a support roller and a holdback body; wherein, the holdback body is a ring cylinder whose inner circle is symmetrically provided with splined holes and the outer circle matches with a support roller bearing mounting; each of the splined holes is provided with a check arc to form an elliptical hole and a check pole. The utility model has the advantages of simple structure, compact size, steady movement, sensitive check, safety, reliability, easy production and low price.
Description
Technical field
The present invention relates to a kind of carrying roller of belt conveyer, particularly a kind of special-purpose holdback of carrying roller that is used for belt conveyer.
Background technology
Existing Non-return idler adopts check bearing or two kinds of anti-reverse modes of ratchet. because the check bearing costs an arm and a leg and makes Non-return idler higher by 50% than common same size carrying roller price; The ratchet Non-return idler life-span is low, and noise is big, and resistance is big.
Summary of the invention
The objective of the invention is to solve present Non-return idler and exist the life-span low, noise is big, shortcoming that resistance is big and expensive deficiency, the back-stop mechanism of a kind of new structure of research and development.
The present invention is achieved through the following technical solutions its purpose: the special-purpose holdback of this carrying roller, form by holdback body 1 and check cylinder 2, holdback body 1 is a circular cylinder, circle rectangular distribution spline 5 in it, be provided with check cambered surface 4 in the spline 5, in each spline 5, be provided with the check cylinder 2 of an activity.
When the special-purpose holdback of carrying roller is used for heavy Non-return idler, in the interior circle of described holdback body 1, can be provided with check cover 3, with the roller carrier shaft close fit.This holdback generally is installed in the roller carrier shaft bearing 6 of carrying roller 8, holdback body 1 and roller carrier shaft bearing 6 close fits, and roller carrier shaft 7 passes the circular hole in holdback.Described holdback body 1 also can be riveted together with roller carrier shaft bearing 6.
The present invention has simple in structure, compact dimensions, and motion is steady, and the check sensitivity is safe and reliable, advantages such as low price easy to manufacture.

The specific embodiment
The carrying roller of belt conveyer is a fixed shaft gear train. roller carrier shaft maintains static, and special-purpose holdback body of this carrying roller and bearing seat close fit, and rotate with carrying roller cylinder.When belt conveyer is normal when clockwise, the movable check cylinder that is provided with is with motion of holdback body in the spline of holdback body, and because of centrifugal action does not contact with roller carrier shaft, holdback is in the contactless state.When conveyer stops, the carrying roller rotative speed is dropped to 0 reverse then by V, this moment, the check cylinder was owing to lose action of centrifugal force, under the effect of gravity, enter afterbody from the spline head, since the diameter of afterbody less than the diameter of check cylinder simultaneously because the effect of holdback body cambered surface, the check cylinder pressed to roller carrier shaft (or check cover) thus and produce friction force and realize reverse check. the size of check power is decided by check cambered surface pressure.For being fit to the need of various Non-return idlers
The invention provides band check cover and be not with two kinds of structures of check cover.
