A kind of rolling bearing retainer and rolling bearing, relate to a kind of rolling bearing retainer structure, described retainer is made up of multiple contact knee-piece (4) and multiple spring body (3) be arranged between every two contacts knee-piece (4), the two ends of each spring body (3) contact knee-piece (4) respectively exterior edge face with two connects, pocket hole (6) is respectively equipped with between the inner face of two contacts knee-piece (4), described rolling bearing comprises described retainer, bearing outer ring (1), rolling element (2) and bearing inner race (5), the ditch coefficient of curvature of described bearing outer ring (1) interior raceway and bearing inner race (5) outer raceway is 0.51-0.515, the surface roughness of described bearing outer ring (1) interior raceway and bearing inner race (5) outer raceway is less than 0.02um, the utility model not only has good self-lubricating property, and avoids bearing rolling element and the mutual collision contacting knee-piece in movement process, effectively reduces vibration, improves bearing life.
Description
[technical field]
The utility model relates to a kind of rolling bearing retainer structure, and specifically the utility model relates to a kind of rolling bearing retainer and rolling bearing.
[background technique]
Known, under some particular surroundings, under the working environment of such as medical machinery, require that precise rolling bearing has the performance of low vibration, due to plain bearing in movement process retainer and rolling element due to mutual collision, the vibration of bearing will be caused, normal requirements of one's work cannot be met, therefore provide a kind of rolling bearing with low vibration performance to become the basic demand of those skilled in the art.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses a kind of rolling bearing retainer and rolling bearing, meeting the object that bearing vibration is in particular circumstances lower.
For realizing above-mentioned model utility object, the utility model adopts following technological scheme:
A kind of rolling bearing retainer, described retainer by multiple contact knee-piece and multiple be arranged on every two contact knee-pieces between spring body form, the two ends of each spring body contact knee-piece respectively exterior edge face with two connects, between the inner face of two contact knee-pieces, be respectively equipped with pocket hole.
Described rolling bearing retainer, is respectively equipped with rolling element in pocket hole, and described rolling element is steel ball or cylindrical roller.
Described rolling bearing retainer, described rolling element contacts with two inner faces contacting knee-piece respectively.
A kind of rolling bearing, comprise the retainer described in the claims, bearing outer ring, rolling element and bearing inner race, bearing outer ring is provided with in the outside of bearing inner race, multiple rolling element is provided with in raceway between bearing outer ring and bearing inner race, multiple rolling element evenly separates by described retainer, in described bearing outer ring, the ditch coefficient of curvature of raceway and the outer raceway of bearing inner race is 0.51-0.515, and in described bearing outer ring, the surface roughness of raceway and the outer raceway of bearing inner race is less than 0.02 um.
Owing to have employed technique scheme, the utility model has following superiority:
1, by adopting steel ball or cylindrical roller as rolling element, effectively reduce in the vibration of bearing in movement process.
2, rolling element contacts all the time with the contact knee-piece of retainer, not only has good self-lubricating property, and avoids bearing rolling element and the mutual collision contacting knee-piece in movement process, effectively reduces vibration, improves bearing life.
3, in bearing outer ring 1 raceway and the outer raceway of bearing inner race 5 be 0.51-0.515, described ditch coefficient of curvature is less, makes bearing have larger adaptation, increases rolling element and raceway groove surface of contact, reduces the vibration of bearing while making rotation more stable.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
In the drawings: 1, bearing outer ring; 2, rolling element; 3, spring body; 4, knee-piece is contacted; 5, bearing inner race.
[embodiment]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples;
Rolling bearing retainer by reference to the accompanying drawings described in 1, described retainer by multiple contact knee-piece 4 and multiple be arranged on every two contact knee-pieces 4 between spring body 3 form, the two ends of each spring body 3 contact knee-piece 4 respectively exterior edge face with two connects, between the inner face of two contact knee-pieces 4, be respectively equipped with pocket hole 6; In pocket hole 6, be respectively equipped with rolling element 2, described rolling element 2 is steel ball or cylindrical roller; Described rolling element 2 contacts with two inner faces contacting knee-piece 4 respectively.
A kind of rolling bearing, comprise the retainer described in the claims, bearing outer ring 1, rolling element 2 and bearing inner race 5, bearing outer ring 1 is provided with in the outside of bearing inner race 5, multiple rolling element 2 is provided with in raceway between bearing outer ring 1 and bearing inner race 5, multiple rolling element 2 evenly separates by described retainer, in described bearing outer ring 1, the ditch coefficient of curvature of raceway and the outer raceway of bearing inner race 5 is 0.51-0.515, and in described bearing outer ring 1, the surface roughness of raceway and the outer raceway of bearing inner race 5 is less than 0.02 um.
Implement rolling bearing retainer described in the utility model and rolling bearing, adopt less ditch coefficient of curvature, bearing is made to have larger adaptation, increase rolling element 2 and raceway groove surface of contact, the vibration of bearing is reduced while making rotation more stable, adopt resilient retainer, rolling element 2 is contacted all the time with the contact knee-piece 4 of retainer, not only there is good self-lubricating property, and avoid bearing rolling element 2 and the mutual collision contacting knee-piece 4 in movement process, effectively reduce vibration, improve bearing life.
The non-detailed portion of the utility model is prior art.
The embodiment selected in this article in order to open goal of the invention of the present utility model, currently thinks to be suitable for, but it is to be understood that the utility model is intended to comprise all changes belonging to the embodiment within the scope of this design and model utility and improvement.
