Recently, the "Precision Shafting Efficient Assembly and Adjustment System" for special bearings developed by ZYS Instrument Development Department has successfully passed user acceptance review and achieved delivery.

This project was officially approved in March 2022. In response to the high-precision and high reliability requirements of precision shafting in spatial mechanisms, the system has been constructed, including bearing protrusion measurement module, paired bearing preload measurement module, bearing precision press fitting module, intelligent high-precision fastening module, and shafting friction torque measurement module. A precision shaft system is a complete process and element management system composed of seven modules, namely the shaft rotation accuracy measurement module and the shaft assembly parameter intelligent monitoring and management module. This system has a systematic solution that includes data monitoring, recording, and anomaly tracing throughout the entire process of bearing selection, shaft component clamping, shaft operation performance detection, and shaft assembly.

In March, after completing the debugging of each sub module of the system and entering the user's site, it was less than 4 months since the system acceptance node specified by the user. Time is tight and tasks are heavy. In order to ensure the project progress is strictly carried out according to the timeline, ZYS has established a 7-member "high-precision driving mechanism efficient installation and system debugging and acceptance team". They have visited the user site multiple times, and all team members have rushed forward, overcame various unfavorable conditions, meticulously debugged various system parameters, and even checked the circuit. The professional level and high-quality service of ZYS project members have been widely recognized by users.

The successful acceptance and review of the "Precision shafting efficient installation system" project not only provides an important help for the department to achieve its business objectives, but also marks the successful transformation of the department from a single, independent equipment as the main order mode to providing a complete set of system solutions for precision shafting installation and detection, which is of strategic significance in the instrument business field of the department. At present, several customers have shown strong interest in such precision axial assembly inspection systems.

In the future, ZYS Instrument Development Department will continue to iterate and improve products, explore potential user needs, cultivate user usage habits, and provide shaft research solutions for the field of precision shaft system clamping and testing.
