Testing machine used for detecting dynamic friction torque of turret seat ring

Abstract

The invention discloses a testing machine for detecting dynamic friction torque of a turret seat ring, belongs to the technical field of turret seat ring tests, and aims to solve the problems of low efficiency, low intelligent degree, high physical output and inaccurate measurement in the prior art. The testing machine comprises a base support frame; a seat ring positioning and clamping device positioned above the base support frame; a torque driving device which is arranged on the base support frame and at least comprises a rotary driving device and a torque sensor, wherein an upper ring anda lower ring of the seat ring are driven by the rotary driving device to rotate relatively; a torque sensor which is arranged on a rotary shaft of the rotary driving device to obtain a seat ring driving torque; and a loading device which comprises a T-shaped sensor mounting support and a loading body. The downward loading force is applied to the T-shaped sensor mounting support through the loadingbody, and the T-shaped sensor mounting support is pushed by a bias driving device to horizontally slide relative to a base plate.

Description

technical field [0001] The invention belongs to the technical field of turret seat ring testing, and in particular relates to a testing machine for detecting dynamic friction torque of a turret seat ring. Background technique [0002] The turret bears the main protective role of armored combat vehicles such as tanks and infantry fighting vehicles. At the same time, it bears the impact load of strong gunpowder gas during the shooting process. The stiffness and strength of the turret and the turret seat ring also have a great influence on the shooting accuracy of the artillery. The turret is connected to the hull by a turret ring. The turret seat ring is composed of upper ring, rolling body, cage and lower ring. The working process is that the lower ring of the seat ring is fixed, and the upper ring is when the axial force is applied downward at the center of the shaft or at a certain offset position. , so that the upper ring rotates relatively. Therefore, it is very necessa...
