Embodiment Construction
[0021] In the on-shaft gear positioning method and positioning device provided by the present invention, a gap is opened on the spline pad of the gear. When installing, the gap faces the positioning key, and the gear can move forward together with the spline pad, so that the gear shaft assembly can be easily loaded into the transmission. After the shell is installed, move the spline pad and the gear back to the gear collar groove, rotate the spline pad, let the gap avoid the positioning key, let any spline align with the positioning key, push it forward, and assemble Finish.
[0022] The present invention is described in detail below in conjunction with accompanying drawing:
[0023] The gear positioning device on the shaft includes a gear shaft, a spline pad and a gear, the outer teeth of the spline pad mesh with the inner teeth of the gear, and the inner teeth of the spline pad mesh with the outer teeth of the gear shaft;
[0024] There is a card slot on the gear shaft. The...

The invention provides a method and a device for positioning gears on a shaft, which mainly solve the problem of incapability of rapidly accurately assembling the traditional speed changer into a transmission shell due to increased gears on a main shaft and lengthened assembly caused by increased gear shifts . The method for positioning the gears on the shaft comprises the following steps: 1) shortening a distance between each two gears; 2) installing the gears into the transmission shell; and 3) recovering each gear to a working position. The device for positioning the gears on the shaft comprises a gear shaft, a spline pad and the gears, wherein external teeth of the spline pad are adaptive to internal teeth of the gears; and internal teeth of the spline pad are adaptive to external teeth of the gears. According to the invention, the structure is simple; the difficult problem that a snap ring structure cannot be designed for gears of a transmission with a small central moment is solved; a new design scheme is provided for limiting the gears of a twin countershaft transmission simultaneously; and due to the design, a twin shaft assembly is easy to assemble, parts are reduced and cost is decreased simultaneously.
Description
technical field [0001] The invention relates to a gear positioning method and a positioning device on a shaft, in particular to a gear positioning method and a positioning device on a shaft in a gearbox. Background technique [0002] With the development of the automobile industry, users need transmissions with many gears and low input torque. Therefore, the demand for small center moment double countershaft transmissions becomes increasingly urgent. [0003] During the assembly process of the small center moment double countershaft gearbox, on the premise of not increasing the volume of the gearbox, the overall length of the two-shaft assembly needs to be shortened before it can be installed in the gearbox. working position; however, when using the existing installation method, the spline pad of the fixed gear restricts the axial movement of the gear, and the key restricts the axial rotation of the spline pad. It is difficult to return to the working position inside, and t...
