Technical Field
The invention relates to an assembling and adjusting method of a backlash eliminating steel wire rope transmission mechanism, and belongs to the technical field of precision instrument assembly.
Background
With the continuous development of the comprehensive technology of the photoelectric system, a high-precision steady aiming technology and a high-precision transmission system become necessary trends of the development at the present stage, and a very high index requirement is provided for the precision of a precision shafting in order to ensure that the photoelectric system accurately captures, aims and tracks a target.
The precision of transmission is mainly determined by the precision of the transmission mechanism and the assembly precision, and for the precise transmission mechanism, higher precision can be achieved only by proper adjustment during assembly. However, for the assembling and adjusting method of the backlash eliminating steel wire rope transmission mechanism, if the assembling method is improper, the requirement of high precision is difficult to achieve.
The existing mainstream transmission mechanisms all rely on gear transmission and chain transmission, the gear transmission efficiency is low, the occupied space is large, the chain transmission needs more links to be adjusted, and the correction is carried out regularly. And both are adjusted with high precision and high complexity. The labor intensity is high, and the working efficiency is low.
