Summary of the invention
For solving the technical problem that prior art exists, it is fixing reliable that goal of the invention of the present utility model is to provide a kind of pressing plate, and pressing plate assembly structure is simple, and reliable pressing plate bearing is closed in assembling.
For achieving the above object, the utility model provides following technological scheme: a kind of pressing plate bearing, include bearing body, the bearing outer ring of bearing body is installed with pressing plate, it is characterized in that: the bearing outer ring outer peripheral surface of described bearing body is provided with positioning step groove, positioning step groove internal fixtion has snap ring, snap ring axial outer end riveting forms the locking flange to the upset of external diameter side, described pressing plate is sleeved on snap ring, pressing plate shaft is spacing to the axial end of positioning step groove on an end face warp beam bearing outer-ring, pressing plate shaft is to other end and locking flange compression fit.
By adopting technique scheme, bearing outer ring sets position stepped slot, positioning step groove realizes the location and installation of snap ring and the location and installation of pressing plate, the axial outer end of snap ring forms locking flange through riveting afterwards, and realize pressing plate and be fixedly mounted on bearing outer ring, structure is simple, the fixed installation of pressing plate is solid and reliable, and snap ring adopts end riveting to form locking flange realization fixing pressing plate, simple to operation, the fixation of pressing plate is reliable.
The utility model is set to further: the axial inner ends place of described positioning step groove is provided with snap ring locking groove, and described snap ring axial inner ends is provided with the location crimp extended to internal side diameter, and described location crimp is installed in snap ring locking groove.
By adopting technique scheme, the axial inner ends of snap ring is locked in snap ring locking groove through location crimp, and snap ring is fixing more solid and reliable, and snap ring have location fixing after, its assembling is more convenient.
The utility model is set to further: described snap ring locking groove extends to and flushes with the axial end of described positioning step groove, described snap ring axial inner ends extends to the axial end of positioning step groove, and the end of described crimp and the axial end of positioning step groove develop.
By adopting technique scheme, pressing plate is reliable and stable with coordinating of snap ring.
The utility model is set to further: described platen edge is provided with location card distribution structure.
By adopting technique scheme, platen edge establishes location card distribution structure, under double clamp bearing assemble, the pressing plate location fit each other of two pressing plate bearings, facilitate the location and installation of pressing plate bearing, and the bearing body number that can realize pressing plate bearing is arranged flexibly, realize being convenient to, in the design of equipment top board bearing unitization, use more flexible.
Below in conjunction with accompanying drawing, the utility model is further described.
