Problems solved by technology

[0004] The purpose of the present invention is to propose a moment load simulator, which is a brand-new way of moment loading, which utilizes a clockwork spring (planar scroll spring) to load the moment, and solves the large and small loading errors of the existing large torque load simulator. The torque load simulator has a limited range of rotation angles and can successfully load the resistance torque on the shaft between the plates

Abstract

The invention discloses a moment load simulator, which is characterized by comprising two X-direction adjusting fixed bottom plates, a Y-direction adjusting fixed support, a Y-direction adjusting fixed bottom plate, a flange shaft coupling, a moment sensor, a corrugated pipe shaft coupling, a speed reducer, a fixed end plate, a clockwork spring box, two adjusting handles, a central spindle, a clockwork spring, a spring box end cover, a deep groove ball bearing and a hollow shaft encoder. In the moment load simulator, moment and the angular velocity of a revolving shaft can be measured; a moment loading way is simple, and is easy to realize; mechanical design of the coaxiality of two working revolving shafts is ensured; and the corrugated pipe shaft coupling can be used for compensating an error between an output shaft of the speed reducer and the shaft end of the moment sensor.

Description

technical field [0001] The invention relates to a moment load simulator, which is used for simulating the resistance moment on the rotating shaft between loading expansion plates. The device can provide torque in a required range, and can adjust the torque within the torque range to provide variable resistance torque, and at the same time can obtain motion information of a moving shaft, and belongs to the technical field of mechanical system experiment facilities. Background technique [0002] A load simulator is a device used to semi-physically simulate the force (moment) load required by an object under laboratory conditions. With the development of science and technology, the requirements for the maneuverability and control accuracy of flight simulators are getting higher and higher, which in turn puts forward higher and higher requirements for the loading performance of the load simulator, which promotes the research progress of the load simulator. [0003] The traditio...
