Description
Technical Field
The invention relates to the field of bearings, in particular to a processing technology of a low-speed full-complement ball bearing.
Background
The bearing is used as an important supporting and transmission component in the mechanical field and is mainly used for bearing radial load. The full complement bearing is one of the bearings, namely more rolling bodies are filled between the inner ring and the outer ring of the bearing, so that the gap between the rolling bodies is reduced, the full complement is basically realized, and the bearing capacity of the bearing is improved.
As is well known, in the process of assembling the rolling elements in the conventional bearing, the inner ring is firstly placed into the outer ring, and is radially offset relative to the outer ring, enough space is left for placing all the rolling elements, then the gap between each rolling element is gradually adjusted, and finally the retainer is installed to maintain the gap between the rolling elements.
However, in a full-complement bearing, because the number of rolling elements is too large, the bearing cannot be completely assembled in a manner that the inner ring is radially offset. At present, the conventional full-complement ball bearing has two main assembling modes, wherein the first mode is that an axial ball filling port is arranged on an inner ring and/or an outer ring of the bearing, and a rolling body is filled from the ball filling port. This approach limits the axial load capacity of the bearing to some extent due to the presence of the ball-filling ports.
In the second mode, the bearing outer ring is arranged in a disconnected mode, the rolling body is placed into the bearing outer ring from the fracture, and the fracture is blocked after the filling is finished. The Chinese patent application with the application publication number of CN104314988A discloses a full ball bearing, wherein a fracture is arranged on an outer ring of the bearing, a clamping block is arranged on the fracture, and the clamping block is connected with the outer ring through a bolt. Above-mentioned full ball bearing because fracture and block are assembled after processing respectively, adopt and get rid of material mode processing, have that the fracture processing degree of difficulty is big, the block assembly degree of difficulty is big, the block and the relatively poor scheduling problem of fracture cooperation precision after the assembly.
Aiming at the problems of the existing full complement bearing, the applicant designs a novel full complement ball bearing which comprises an inner ring, an outer ring and a rolling body, wherein a broken joint is arranged on the outer ring, and the broken joint respectively penetrates through the outer ring along the axial direction and the radial direction. During assembly, the outer ring expands outwards, and the outer ring resets after the rolling body is installed.
Above-mentioned neotype full complement ball bearing adopts the mode processing of not getting rid of the material, does not set up the block, can simplify the structure, reduces processing and assembly procedure. Because the structure and the assembly mode of the full complement ball bearing are not circulated in the prior art, how to efficiently and reliably complete the assembly of the full complement ball bearing is the core technology of the scheme.
