AI Technical Summary

Technical Problem

When installing short-wheelbase components in confined spaces, couplings cannot effectively compensate for coaxiality deviations, requiring frequent adjustments by moving the drive motor or gearbox. This affects assembly efficiency, necessitates high-power equipment, and is heavy and difficult to operate.

Method used

A short-pitch compensated double cross coupling is designed. By setting a cross intermediate piece between the driving fork and the driven fork, and providing a gap between the driving spline and the driven spline and the spline hole, the compensation margin for radial or axial deviation is increased, and the assembly process is simplified.

Benefits of technology

It enables effective compensation for coaxiality deviation in confined spaces, simplifies the assembly process, improves assembly efficiency, avoids frequent movement of high-power equipment, and reduces operational difficulty.

Abstract

A short-pitch compensated double cross coupling includes a driving fork, a driven fork, and a cross intermediate member, as well as a driving spline and a driven spline. The outer ends of the two lugs of both the driving and driven forks are provided with pin holes. Two driving pins are symmetrically arranged on the side of the driving spline, which is fitted into the driving fork, and the two driving pins are correspondingly inserted into the two pin holes of the driving fork. A connecting hole is provided within the driving spline. Two driven pins are symmetrically arranged on the side of the driven spline, which is fitted into the driven fork, and the two driven pins are correspondingly inserted into the two pin holes of the driven fork. A connecting hole is provided within the driven spline. A spline hole is provided within the cross intermediate member, and the driving and driven splines are coaxially fitted into the spline hole from both ends. A clearance is provided between the driving spline, the driven spline, and the spline hole. This coupling increases the compensation margin for radial or axial misalignment of the cross coupling, avoiding the need for frequent movement of the drive motor or gearbox to achieve docking assembly, thus simplifying the assembly process and improving assembly efficiency.
