Summary of the invention
The present invention is directed to above-mentionedly, purpose is to provide a kind of multi-functional V band fatigue tester of replacing that can the Rapid Realization belt wheel.
Technical scheme of the present invention is: the present invention includes control device, be arranged on the motor on the support; The output terminal of motor connects test unit; Test unit comprises driving pulley and driven pulley, and driven pulley is arranged on cunning moving up and down and takes, and the slide lower end connects loading system through pull bar; It is characterized in that, be connected with drive plate between motor and the driving pulley and between driving pulley and the driven pulley.
Said control device comprises the CPU control module, CPU control module control rate unit, performance element, sample state detection unit, counting unit.
Advantage of the present invention is: the present invention is on the basis of the patent No. 2005200696175; Corresponding parts are improved, mainly contain following advantage: 1) the present invention is being connected with drive plate between motor and the driving pulley and between driving pulley and the driven pulley, like this when needs are according to circumstances changed belt wheel; Just need belt wheel not dismantled from main shaft; But belt wheel is dismantled from drive plate, newer belt wheel being connected on the drive plate, dismounting is very convenient; And can not cause the reduction of transmission accuracy because of the replacing of belt wheel, guarantee test accuracy; 2) the present invention adopts CPU control, and control accuracy further improves, and the testing machine job stability is also greatly guaranteed.
