Transmission device used for impulse response spectrum testing stand

Abstract

The invention discloses a transmission device used for an impulse response spectrum testing stand. The impulse response spectrum testing stand comprises a stand body which comprises a stand seat, a door frame, a working stand surface and a transmission device; the transmission device comprises a pendulum bob component comprising a pendulum bob, a pendulum bob arm and a pendulum bob shaft; the transmission device also comprises a worm and gear deceleration motor which is fixedly connected and is opposite to the door frame; the pendulum bob shaft is in transmission connection with the worm and gear deceleration motor; a power output shaft of a worm and gear deceleration motor coaxially drives the pendulum bob shaft to rotate so as to lift the pendulum bob; the power output shaft and the pendulum bob shaft are in transmission connection through a tooth-embed clutch; and, furthermore, the transmission device also comprises a brake which is acting on the pendulum shaft. The invention simplifies the device structure, eliminates the post adjustment and provides convenience to post maintenance. Besides, the invention also has a self-locking function, can realize the power off protection and is safe and reliable.

Description

Technical field [0001] The invention relates to the field of environmental mechanics test equipment, in particular to an impact response spectrum test bench, in particular to a transmission device used for the impact response spectrum test bench. Background technique [0002] The impact test bench is a kind of mechanical environment test equipment, which is mainly used for the tests that require the use of the impact test bench in the fields of weapon equipment, aerospace, etc., instead of the original standard pulse impact test. The impact test bench is mainly used to simulate the environment where the product is subjected to impact during use, loading and unloading and transportation to determine the product's adaptability to various impact forces. Through such an impact test, the integrity of a product structure can be evaluated, and a reasonable basis can be provided for evaluating the quality of the product. [0003] The transmission mechanism of the existing impulse response...

Problems solved by technology

There are the following deficiencies: 1. The method of using a motor plus an electromagnetic clutch, because the electromagnetic clutch will wear out during use, requires constant maintenance and adjustment as the use time increases; 2. The hydraulically driven transmission mechanism requires an additional oil source The device has a complex structure, the hydraulic oil must be replaced regularly, and the maintenance is relatively cumbersome
