Composition and the rolling action of the parts'

 Kunshan bearings: Rolling bearing are the outer ring, inner ring, rolling elements and cage four parts. Its structure shown in Figure 1-1 (see Appendix) usually bearing outer ring mounted on the machine base hole is fixed, the inner ring is mounted on the shaft for rotation therewith, and the rolling elements are included, the outer ring of the roll Road between rolling, forming rolling friction.
An outer ring: usually wind turbine earing outer ring or mechanical casing hole forming transition fit, play a supportive role.
Two inner rings: the inner ring and the shaft is usually closely with together with the shaft running.
3 rolling: rolling elements (balls, rollers or needle) in the bearing retainer means generally arranged evenly between the two rings for the rolling motion, its shape, size and number of direct impact and load bearing capacity using performance.
4 Cage: Cage addition to the possibility of rolling evenly spaced outside, but also from the guide roller rotation and improving internal bearing lubrication and so on.
Cage can be divided into five types, namely: wave type cage, crown-shaped cage, E-type cage, solid cage, daisy type cage.
5 dust cover and seals: Rolling addition to the four main components of the composition outside, some bearing shields or seals needed.
The role is to keep the external dust cover dust intrusion bearing.
Removable dust cover - commonly known as "flap"
Non-removable dust cover - commonly known as the "dead head" "Fixed Cover"
Function is to keep the outside seal oil, water penetrated into the bearing.
Contact seals
   Non-contact seals
