Abstract
Disclosed in the utility model is a kind of one-direction bearing structure, comprise outer ring, roller, retainer and inner ring, described roller is arranged on retainer, retainer is arranged between inner ring and outer ring, the inner side of outer ring evenly offers unidirectional multiple restraining groove, and the outside of retainer also evenly has the projection of equal number; And also elastic component is housed between retainer and roller, the outer surface of described outer ring has garland groove, bearing gland is fixed on the periphery of outer ring, bearing gland and outer ring plastic shaping, bearing gland having mounting hole is major character, there is structure simple, while reducing assembly technology, ensure that unilateral bearing and bearing gland such as reliably to fix at the feature.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of one-direction bearing structure.
Background technique
Automatic washing machine is in running, and interior bucket can only unidirectional turn, and another direction is in locking state, and locking function is realized by unilateral bearing.Current conventional one-direction bearing structure, be take after force fit bearing housing with gland with the use of, which adds transition piece one bearing housing.Structure and mounting process are comparatively complicated, too increase the cost of whole parts simultaneously.
Summary of the invention
The purpose of this utility model is, provides a kind of structure simple, while reducing assembly technology, ensures the unilateral bearing that unilateral bearing and bearing gland are reliably fixed, to overcome the deficiency of prior art.
The utility model realizes its object technological scheme:
A kind of one-direction bearing structure, comprise outer ring, roller, retainer and inner ring, described roller is arranged on retainer, and retainer is arranged between inner ring and outer ring, the inner side of outer ring evenly offers unidirectional multiple restraining groove, and the outside of retainer also evenly has the projection of equal number; And also elastic component is housed between retainer and roller, the outer surface of described outer ring has garland groove, and bearing gland is fixed on the periphery of outer ring, bearing gland and outer ring plastic shaping, bearing gland has mounting hole.
The garland groove that described outer ring outer surface has is cross recess.
Described elastic component is " Z " shape spring.
After adopting said structure, outer surface due to outer ring has garland groove, bearing gland is fixed on the periphery of outer ring, bearing gland and outer ring plastic shaping, use plastic moulding process, eliminate transition member one bearing housing, bearing and bearing gland are directly injection molded into one, have simplified structure space, have also saved the time of processing simultaneously, improve working efficiency, more decrease the appearance of defect ware.
Again bearing gland has mounting hole, can be fixed by screws in desired location, librarian use convenient for assembly.
And the garland groove that described outer ring outer surface has is cross recess, it is more tight that such structure can make outer ring and bearing gland to fit, and facilitates plastic shaping.
After technique scheme is implemented in full, the utility model has rational in infrastructure, easy to use, and while can saving operation, ensureing the feature that bearing and bearing gland are reliably fixed, is self-evident.
