In addition, when machining, stress concentration is inevitably generated at the included angle between the end face of the retainer and the root of the connecting column, so that the two half retainers are not tightly connected, the stress of the roller is unbalanced, the roller is deformed, and the service life of the bearing is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides an use from riveting cylindrical roller bearing who keeps ware solves spliced pole root and half holder terminal surface junction burr problem through optimizing, avoids spliced pole root stress concentration phenomenon to produce simultaneously.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides an use cylindrical roller bearing of self-riveting holder, includes inner circle, outer lane, roller and holder, the holder comprises half first holder and half holder of second, and wherein half first holder has the holder seat, the one end of half first holder main part has the spliced pole, and the terminal circumference of this spliced pole extends and forms the connection cap, and the diameter of connecting the cap is greater than the diameter of spliced pole, half holder of second have with holder seat complex step hole structure, this step hole structure fixed mounting is in spliced pole department, half first holder terminal surface is close to spliced pole department and is equipped with the annular groove around the terminal setting of spliced pole.
Preferably, the cross-section of the groove is hemispherical.
Preferably, the ratio of the opening width of the groove to the diameter of the connecting column is 1: 4-1: 8.
Preferably, the junction between the outer annular surface of the connecting column and the inner wall of the groove is in smooth transition.
Use the utility model discloses a beneficial effect is:
this cylindrical roller bearing sets up the slot in the transition department of spliced pole and first half holder terminal surface, and the burr that processing produced is held through the slot in first half holder terminal surface position to the slot setting simultaneously, through the setting of slot, avoids producing stress concentration in spliced pole root department, avoids the riveting department deformation of first half holder and the half holder of second, prolongs the life of bearing, reduces the bearing noise.

Detailed Description
In order to make the purpose, technical solution and advantages of the present technical solution more clear, the present technical solution is further described in detail below with reference to specific embodiments. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present teachings.
Example 1
As shown in fig. 1 and 2, the cylindrical roller bearing using the self-riveting retainer proposed by the present embodiment includes an inner ring 10, an outer ring 20, rollers 30 and a retainer 40, where the retainer 40 is composed of a first half retainer 41 and a second half retainer 42, where the first half retainer 41 has a retainer seat, one end of a main body of the first half retainer 41 has a connection column 412, a terminal end of the connection column 412 extends circumferentially to form a connection cap 413, and a diameter of the connection cap 413 is greater than a diameter of the connection column 412, the second half retainer 42 has a stepped hole structure matched with the retainer seat, the stepped hole structure is fixedly installed at the connection column 412, and an annular groove 4111 arranged around the terminal end of the connection column 412 is arranged on an end surface 411 of the first half retainer 41 near the connection column 412.
In this embodiment, the holder base is the sum of the end surface 411 of the first half holder 41, the connecting column 412, and the connecting cap 413.
