It is described upper piece and the side of bottom sheet be each provided with boss, the slope of the boss both sides is respectively China and foreign countries' roller surface
Roller surface in in；
Described multiple rolling elements be arranged at China and foreign countries' roller surface and outer roller surface, between roller surface and interior roller surface,
And with contact angle r, and can freely roll；
Described multiple rolling elements are kept by retainer, and described retainer includes annular support body, annular beam body and outer
Annular frame, is connected between the annular support body and outer annular frame by annular beam body, the annular support body and annular
Connection is tilted between beam body, acute rake angle is ∝, tilts and connect between outer annular frame and annular beam body, acute rake angle is ∝,
Annular support body and outer annular frame are inclined at the same side of annular beam body and are formed with oil storage tank；Described annular
It is provided with multiple interior pocket holes, described outer annular frame along outer annular frame circumference and sets along annular support body circumference on support body
There is the outer pocket hole with the number such as interior pocket hole, described each interior pocket hole corresponds to an outer pocket hole on same RADIAL；Roll
Body is arranged in interior pocket hole and outer pocket hole.
Described interior pocket hole and outer pocket hole are circular pocket hole.
Described rolling element is steel ball.
Described retainer is enhancing nylon material integrated injection molding.
R=40 ° of described contact angle, acute rake angle ∝=50 °.
After said structure, the utility model is compared to the prior art advantageously：The utility model is used
Four row rolling elements are designed, and rolling element angular contact so that this thrust bearing can bear load axially and radially, and carrying energy
Power is greatly improved.
