The transition fit is adopted, the fit quantity between the parts is proper, the service life of the device is prolonged, and the working cost is reduced. When the transition matching is adopted, the assembly is more convenient, and once the parts are damaged due to unreliability, the parts are well disassembled during replacement.
If interference fit is adopted in the assembly process, the interference is too large and is easy to deform, the risk of device blocking is increased, the difficulty is increased during disassembly and maintenance, and other parts are possibly damaged.
If clearance fit is adopted in the assembly process, the fit surfaces between the parts can be worn rapidly due to relative sliding, and the working performance of the device is affected.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
