The invention provides a verification device and method for gear press-fitting.The verification device comprises a supporting base, a press machine, a press-fitting workpiece and a control assembly; the press machine comprises a pressure shaft, a pressure head, a press-fitting assembly, a first sensor and a second sensor; the press-fitting workpiece comprises a press-fitting gear and a press-fitting gear shaft; the first sensor detects and displays the acting force of the pressure head on the press-fitting assembly; and the second sensor detects and displays the displacement value of the press-fitting gear in a press-fitting gear shaft. According to the verification device and method for gear press-fitting, the first sensor and the second sensor are arranged on the device, so that the press-fitting force and the press-fitting displacement of gear press-fitting are verified through the device, the interference magnitude of assembly between the gear and the gear shaft is further controlled, and the problem that in the prior art, in the press-fitting force control range between a gear and a gear shaft, the interference magnitude of assembly between the gear and the gear shaft cannot be controlled, the performance of a product is affected, and potential safety hazards are increased are solved.
Description
technical field [0001] The invention relates to the technical field of press-fitting, in particular to a verification device and method for gear press-fitting. Background technique [0002] With the development of the times and the continuous improvement of people's living standards, cars are used more and more frequently. As an important component in the power system of a car, the transmission's assembly quality directly affects the driving performance and safety performance of the vehicle. Among them, the assembly of gears and shafts in the transmission assembly is the key control process in the transmission assembly process. In the structural design of gears and shafts in automotive transmission assemblies, the press-fit design structure of gears and shafts is widely used. [0003] In the design of the gear press-fitting process, the limit value of the press-fitting force of the press-fitting fit between the gear and the gear shaft can be controlled within the force value...
