Abstract
The invention discloses a primary and secondary bearing, and belongs to the field of transmission parts. The primary and secondary bearing is used for achieving the purpose of improving safety. According to the technical scheme, the primary and secondary bearing is composed of an inner ring, a middle ring, an outer ring, a retainer and rolling bodies, wherein the position between the inner ring and the middle ring and the position between the middle ring and the outer ring are each provided with a set of rolling bodies. By the adoption of the structure, when the primary and secondary bearing is in use, the two sets of rolling bodies of the bearing will work in a complementary manner; if one set of rolling bodies cannot work because something happens to the set of rolling bodies, a user does not need to worry about potential safety hazards, and the safety of the bearing is greatly improved.
Description
Technical field
The invention belongs to driving parts field, be specifically related to a kind of Primary and secondary bearing.
Background technique
Traditional bearing has two inner rings and an outer ring, and there is one group of rolling element centre, and when rolling element breaks down time, bearing just fails, and therefore, in this, design has certain potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Primary and secondary bearing, in order to reach the object improving its Security.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Primary and secondary bearing, it is characterized in that, this bearing is made up of inner ring, centre circle, outer ring, retainer and rolling element four parts, and one group of rolling element is respectively settled in inner ring and centre circle, centre circle and outer ring.
A kind of Primary and secondary bearing provided by the invention, by adopting above-mentioned structure, during use, two groups of rolling elements of this bearing will complementary work, if one group of rolling element occurs that what situation cannot work, do not worry any potential safety hazard yet, substantially increase the Security of bearing.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is overall structure schematic diagram of the present invention.
In figure: outer ring 1, centre circle 2, rolling element 3, inner ring 4, retainer 5.
Embodiment
As Primary and secondary bearing a kind of in Fig. 1, this bearing is made up of inner ring 4, centre circle 2, outer ring 1, retainer 5 and rolling element 3 four parts, and inner ring 4 respectively settles one group of rolling element 3 with centre circle 2, centre circle 2 with outer ring 1.
A kind of Primary and secondary bearing provided by the invention, by adopting above-mentioned structure, during use, two groups of rolling elements 3 of this bearing will complementary work, if one group of rolling element 3 occurs that what situation cannot work, do not worry any potential safety hazard yet, substantially increase the Security of bearing.
