Deformable outer cone drum-shaped gapless spline structure

Abstract

The invention discloses a deformable outer cone drum-shaped gapless spline structure for connecting an input shaft of a speed reducer to be detected with a high-speed end transmission shaft of a speedreducer detector, and connecting an output shaft of the speed reducer to be detected with a low-speed end transmission shaft of the speed reducer detector. The spline structure comprises a connectingshaft and a matching hole, wherein the connecting shaft is connected on the input shaft / the output shaft of the speed reducer to be detected; the matching hole is connected on the transmission shaftsof the high-speed end / the low-speed end of the speed reducer detector; and the connecting shaft is an involute outer spline, the matching hole is an involute internal spline, and the connecting shaftand the matching hole are connected through the involute outer spline and the involute inner spline which are matched with each other, thereby achieving large-torque transmission. According to the deformable outer cone drum-shaped gapless spline structure, rapid gapless connection and transmission of a separable shafting can be ensured, large torque transmission is realized, a certain coaxial error is tolerated, and the positioning of a fixed outer shell is not affected.

Description

technical field [0001] The invention relates to mechanical transmission technology, in particular to a deformable outer cone drum-shaped gap-free spline structure, which is mainly used in fast and gap-free connection and transmission of separable shaft systems in precision mechanical transmission systems. Background technique [0002] The reducer is widely used in the industrial automation industry to realize the function of converting high-speed low-torque into low-speed high-torque. The existing mechanical transmission has higher and higher requirements on the performance index of the reducer, especially in the field of industrial robots, the reducer is used as a transmission joint, and its performance seriously affects the working accuracy and service life of the system. is particularly important. [0003] At present, the existing reducer detectors on the market have a horizontal structure and a vertical structure, both of which need to connect the tested reducer to the ...

AI Technical Summary

Problems solved by technology

In order to realize the replacement of the reducer, for the connection of the transmission shaft, some schemes adopt bolt connection, which is difficult to ensure a good coaxiality and cannot be quickly replaced, and transmits large torque

There are also some schemes where the transmission shaft is connected by rectangular splines or involute splines, but the general type can be used for sliding splines. There is a clearance that will cause errors in the angle measurement of the reducer, and additional error compensation methods are required to realize the angle. accurate measurement
