Technical Field
The invention belongs to the technical field of mechanical assembly, and particularly relates to a method for mounting a spring steel ball of a rotating body of a side speed reducer.
Background
When the side speed reducer is assembled, the inner side of the tool bolt is required to be compressed by a spring to provide supporting force, two ends of the spring are respectively propped against one steel ball, and when the input shaft and the tool bolt rotate relatively, the steel balls rotate along with the input shaft to support the rotating body, so that the friction coefficient in the movement process of the rotating body is reduced, and the rotation precision of the rotating body is ensured.
However, in the process of assembling the side speed reducer, because the spring stiffness is larger, the assembling position is complex, the structure is compact, in order to accurately mount the steel balls in place, a screwdriver is generally used for compressing the spring, and then the steel balls are placed. However, the assembly success rate of the existing assembly method is lower, generally less than 10%, and the assembly efficiency is very low. The phenomenon that the side speed reducer assembled by the existing method is unsmooth in rotation occurs, and the surface of the steel ball is found to be severely scratched by disassembly, wherein the scratches are caused by using a screwdriver or a non-customized tool in the process of assembling the spring and the steel ball, so that the steel ball is unsmooth in rotation, and the quality of the side speed reducer is directly affected. The use of a screwdriver or an off-the-shelf tool for assembly has the further problem that the compression of the spring and the simultaneous positioning of the steel balls is not possible, which can easily lead to loss of the steel balls.
In order to improve the assembly efficiency and the assembly quality of the bolt part spring and the steel ball of the side speed reducer tool, development of an installation tool for assembling the spring steel ball is needed to be urgently needed to improve the assembly precision, and the aim of improving the assembly quality of the side speed reducer is achieved by improving the assembly quality of the part.
