Main cone elastic guide press-loading device

Abstract

The invention relates to a main cone elastic guiding pressing mechanism. The mechanism is characterized in that a lower supporting pressure head which can dynamically go upward along the axial point of a lower oil cylinder in a double acting compressor system, the lower supporting pressure head is a casing pipe structure, a guiding pressure head is coaxially arranged inside the inside the lower supporting pressure head pipe, the end surface of the tail end of the guiding pressure head is supported by a pressure spring inside the lower supporting pressure head pipe, and the guiding pressure head can axially slide inside the lower supporting pressure head pipe; the upper section of the guiding pressure head is a truncated cone body with larger upper end and smaller lower end, the upper section pipe of the lower supporting pressure head is a straight pipe section which can hold the truncated cone body, the truncated cone body in the upper section convexly of the guiding pressure head supported by the pressure spring inside the lower supporting pressure head pipe is extended on the top end surface of the lower supporting pressure head, and the bearing to be assembled and the retainingring used for the shaft are sheathed on the periphery of the truncated cone body with the purpose that the retaining ring for the shaft is arranged at the upper part and the bearing is arranged at the lower part. The one-time, rapid and accurate automatic assembly for the bearing and the retaining ring for the shaft of the main reducing gear of a vehicle can be realized, and the effect on the assembly quality of the main reducing gear by human factors is greatly reduced.

Description

technical field [0001] The invention relates to a main cone elastic guide press-fitting mechanism, more specifically a main cone elastic guide press-fit mechanism for completing the assembly work of the bearing on the main cone and the retaining ring for the shaft in the assembly process of the main reducer. Background technique [0002] The main reducer of an automobile is an important part of the automobile transmission system. Its main function is to increase the input torque and reduce the speed accordingly, and it also has the function of changing the direction of torque rotation when the engine is placed vertically. The main reducer of an automobile mainly realizes its main function through a pair of active and passive bevel gears that maintain normal meshing with each other. In order to ensure that the active bevel gear has sufficient support rigidity, the active bevel gear is generally made into one with the shaft and is called the main drive. Cone, and the main cone...

Problems solved by technology

Therefore, when assembling the guide bearing and shaft retaining ring to the main cone, they must be assembled in place to prevent the normal meshing position of the active and passive bevel gears from changing, causing damage to the active and passive bevel gears, and making the main reducer unable to work normally.

[0003] In the existing assembly process of the main reducer, the assembly process of the bearing on the main cone and the retaining ring for the shaft is not well controlled, and it is generally carried out manually by the assembly workers using general tooling. In this assembly process, on the one hand, artificially random The stability of the product is relatively large, resulting in unstable product quality. On the other hand, the bearing and shaft retaining ring need to be assembled to the main cone step by step. There are flipping and moving, and there are many assembly tools, resulting in high labor intensity and low production efficiency.
