Self-driven seat ring

Abstract

The invention relates to a self-driven seat ring which comprises a motor, a driver, a position sensor, a slipring, a supporting bearing and a load. The motor is composed of a stator and a rotor, the stator is connected with the outer ring of the supporting bearing and the slip ring stator and then fixed to a vehicle body together, and a stator winding is connected with the driver. The rotor is connected with an inner ring of the supporting bearing and is divided into a sensor end and an output end, the rotor sensor end is connected with the position sensor rotor, and the rotor output end is connected with the load; the slip ring stator is connected with the position sensor shell, the slip ring rotor is connected with the position sensor rotor, the slip ring rotor electrical part is respectively connected with the electrical parts of the position sensor and the load, and the slip ring stator electrical part is connected with the driver. Compared with the scheme of a driving motor and agear speed reducer, the system precision and the efficiency are improved, transmission gaps, vibration, noise, abrasion and the like are eliminated, meanwhile, the manufacturing process and the assembling difficulty is greatly reduced, and the subsequent use maintainability is improved.

Description

[0001] Technical field [0002] The invention relates to the technical field of automatic weapon stations and automatic turrets, in particular to a self-propelled seat ring. Background technique [0003] At present, the mechanical structure of the seat ring of traditional turrets and weapon stations at home and abroad often adopts the cascade drive scheme of "drive motor + gear reducer". Regardless of the electro-hydraulic or all-electric gun control system, in order to improve the response speed of the turret, the power components usually use high-speed motors, which requires the addition of multi-stage reducers to amplify the output torque to bring the load to motion. As we all know, the use of multi-stage gear reduction will reduce the transmission accuracy of the seat ring, increase vibration and noise, etc., and there are inevitably transmission gaps, gear elastic deformation and wear problems in the gear transmission device, and the adoption of this scheme will increase ...

Problems solved by technology

As we all know, the use of multi-stage gear reduction will reduce the transmission accuracy of the seat ring, increase vibration and noise, etc., and there are inevitably transmission gaps, gear elastic deformation and wear problems in the gear transmission device, and the adoption of this scheme will increase the system manufacturing process. Difficulty and assembly difficulty will further increase the subsequent use and maintenance cost of the seat ring

At the same time, the nonlinear link in the above-mentioned transmission chain will have a significant impact on the stability, low-speed performance and stable accuracy of the gun control system, which restricts the performance of the fire control system of the turret and weapon station, thereby reducing the battlefield survival rate
