Lubricating fluid is flowed out from the first micropore when bearing operation so that and the roller surface of bearing is effectively lubricated, so as to avoid
Roller generates rigid friction after long-time rolls with the inner wall of retainer so that retainer and bearing have longer service life, water
Flat supporting rod is the length of the stretching for limiting spring, and the length that first baffle stretches out lubrication column from the first micropore is avoided to spend
It is long；
（2）The utility model is when bearing shuts down, and due to inertia, spring is shunk back, and drives in lubrication column
First baffle shelters from the first micropore so that and the lubricating fluid in lubrication column will not be flowed out excessively, avoid the waste of lubricating fluid, and
The setting of second baffle so that when spring is shunk back, due to the contact-impact of second baffle and fixed link, mitigate spring to recycle
The elastic force of contracting so that first baffle is more rapid to shelter from the first micropore.

Specific implementation mode
With reference to specific embodiment, the utility model is described in further detail：
A kind of roller bearing retainer, the retainer include symmetrically arranged two end caps 1, two end caps 1 it
Between connected by connecting pole 2, and the connecting pole 2 is uniformly arranged along end cap 1 is circumferential, the gap between two neighboring connecting pole 2
It is placed with roller, the roller outer layer is coated with scuff-resistant coating, and the is respectively equipped on the end cap between the two neighboring connecting pole 2
One groove 3 is respectively equipped with the second groove on the opposite both sides inner wall of the two neighboring connecting pole 2 so that retainer rotated
Cheng Zhong reduces the contact area of roller and retainer, reduces the service life that friction increases roller and retainer.
