Abstract

The invention relates to a speed-increasing azimuth sensor. The sensor includes: a connecting cover, a gear seat and a base arranged sequentially from top to bottom; an upper and lower gear assembly arranged horizontally and two ends are respectively provided with an upper cover and a lower cover A cross-shaped anti-backlash gear assembly composed of a vertically arranged rotating shaft; the upper cover of the upper end of the rotating shaft is arranged in the groove at the outer end of the connecting cover, and the hollow shaft of the encoder located in the base is arranged at the lower end Inside; the upper and lower gear assemblies are located between the connecting cover and the gear seat, and the outer end extends to the outside of the connecting cover, gear seat and the base. The technical scheme provided by the invention solves the problem of low accuracy of the traditional turret azimuth angle sensor, simplifies the sensor structure, eliminates the gear backlash error, reduces the transmission error, and improves the angle measurement accuracy.

Description

technical field [0001] The invention relates to the technical field of angle measurement, in particular to a speed-increasing azimuth sensor. Background technique [0002] In armored vehicles, turret azimuth sensors and positioning and orientation devices are the basis for achieving target sharing and coordinated strikes. The measurement accuracy of the azimuth sensor of the turret is the technical guarantee for the precise strike of the target. [0003] The traditional turret azimuth sensor uses a rotary connector, a gear train, and a connecting bearing to measure the angular velocity of the turret rotation, and obtain the angle of rotation of the turret through conversion. Its gear train is complicated, and it meshes with the turret seat ring in deceleration, so the measurement accuracy is low. In addition, the non-parallel error of the mounting shaft between the gear trains of the traditional sensor and the backlash error between the gear meshes lead to low measurement ...
