Abstract
The utility model relates to a kind of selfaligning roller bearing pressing cage.It comprises body, and this body is short cylinder shape, and its one end is open state, and the other end has end face, and this end face has center hole.The external diameter of described body open end is greater than the external diameter of the other end, and the sidewall of body is spheric.The sidewall of described body is circumferentially evenly equipped with roller pocket hole.Be characterized in that described body end face is circumferentially evenly equipped with radiation hole between center hole and outward edge.Adopt this pressing cage, selfaligning roller bearing can be made all to have good smooth effect, and the chip produced that rolls easily is discharged, this pressing cage has good radiating effect simultaneously, and working life is longer.
Description
Technical field
The utility model relates to a kind of selfaligning roller bearing, is the selfaligning roller bearing pressing cage with heat sinking function specifically.
Background technique
As everyone knows, bearing is a kind of component used in machinery widely, and its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.Existing bearing is mainly divided into rolling bearing and the large class of sliding bearing two, wherein rolling bearing is all made up of outer ring, inner ring, retainer and roller, retainer can be divided into pressing cage, solid cage etc. again, pressing cage has good resistance to high temperature because it adopts metallic material to make, and is widely used in machinery.
Traditional selfaligning roller bearing pressing cage comprises body, and this body is cylindrical shape, and its one end is open state, and the other end has end face, and this end face has center hole; The external diameter of described body open end is greater than the external diameter of the other end, and the sidewall of body is spheric; The sidewall of described body is circumferentially evenly equipped with roller pocket hole.During use, two pressing cages are needed to be enclosed within outside the inner ring of bearing by the docking of its open end, the external diameter of inner ring should be suitable with pressing cage end-face central hole, and make there is barrel shaped roller in the roller pocket hole of two pressing cages, outside pressing cage, then overlap outer ring.As shown in Figure 1, but, in the mounted state, because this pressing cage 4 end-face central hole must be suitable with inner ring 1 external diameter, therefore relative closure inside this end face, the lubricant grease of bearing can not be entered in the raceway of barrel shaped roller 2 and inner ring 1 smoothly, and the lubrication effect between barrel shaped roller 2 and raceway is poor, and the chip produced that rolls not easily is discharged.Meanwhile, the relative closure inside this end face, barrel shaped roller 2 heat that high speed scroll produces on raceway is not easily shed, and the easy moulding retainer of Long-Time Service is out of shape and damages bearing, and working life is shorter.
Model utility content
Problem to be solved in the utility model is to provide a kind of selfaligning roller bearing pressing cage, adopt this pressing cage, selfaligning roller bearing can be made all to have good smooth effect, and the chip produced that rolls easily is discharged, this pressing cage has good radiating effect simultaneously, and working life is longer.
For solving the problem, take following technological scheme:
Selfaligning roller bearing pressing cage of the present utility model, comprises body, and this body is cylindrical shape, and its one end is open state, and the other end has end face, and this end face has center hole.The external diameter of described body open end is greater than the external diameter of the other end, and the sidewall of body is spheric.The sidewall of described body is circumferentially evenly equipped with roller pocket hole.Be characterized in that described body end face is circumferentially evenly equipped with radiation hole between center hole and outward edge.
Take such scheme, have the following advantages:
Because the body end face of selfaligning roller bearing pressing cage of the present utility model is circumferentially evenly equipped with radiation hole between center hole and outward edge, therefore, after being loaded selfaligning roller bearing, lubricant grease can join in the middle of roller and inner ring raceway in these radiation holes, lubrication effect between roller and raceway is better, and the chip produced that rolls also can be discharged in this radiation hole.Meanwhile, the major function of this radiation hole is exactly effectively shed by the roller heat that high speed scroll produces on raceway, and make this pressing cage not yielding, selfaligning roller bearing is not fragile, and working life is longer.
Accompanying drawing explanation
Fig. 1 is the using state schematic diagram of traditional selfaligning roller bearing pressing cage;
Fig. 2 is the perspective view of selfaligning roller bearing pressing cage of the present utility model;
Fig. 3 is the schematic cross-section that selfaligning roller bearing pressing cage of the present utility model is arranged on bearing;
Fig. 4 is the right elevation of Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 2, selfaligning roller bearing pressing cage of the present utility model, comprises body 5, and this body 5 is cylindrical shape, and its one end is open state, and the other end has end face, and this end face has center hole 8, and this center hole 8 is for matching with the inner ring of bearing.The external diameter of described body 5 open end is greater than the external diameter of the other end, and the sidewall of body 5 is spheric.The sidewall of described body 5 is circumferentially evenly equipped with roller pocket hole 6.Described body 5 end face is circumferentially evenly equipped with radiation hole 7 between center hole 8 and outward edge.
As shown in Figure 3, Figure 4, during use, two selfaligning roller bearing pressing cages of the present utility model are enclosed within outside the inner ring 1 of bearing by the docking of its open end, the external diameter of inner ring 1 should be suitable with pressing cage end-face central hole 8, and make there is barrel shaped roller 2 in the roller pocket hole 6 of two pressing cages.Meanwhile, inner ring 1 corresponding inside two pressing cage joints needs arrange the ring holder 9 for supporting pressing cage, this ring holder 9 can guarantee that two pressing cages remain mated condition accurately, bearing is rotated smooth and easy.Then, outside pressing cage, outer ring 3 is overlapped.
