[0005] No matter it is the most common tensioning device or the tensioning method involved in the above-mentioned utility model, it must be provided with an idler or a biasing mechanism on each transmission belt. If the above-mentioned transmission mechanism is a secondary belt transmission, then it must be At least two or more idlers or biasing mechanisms are required, and because the existing tensioning devices require springs or other similar elastic parts, the elastic parts are e

Abstract

The present invention relates to a two-stage belt-driven belt tightness regulating mechanism. It is characterized by that it includes first clamping plate, second clamping plate, mounting plate and compression sleeve. Said first clamping plate and second clamping plate are spaced and parallelly-arranged, two ends of intermediate rotating shaft are respectively set on the first clamping plate and second clamping plate; on end of mounting plate is turnably hinged on the frame. Besides, said mechanism also includes first drive wheel and second drive wheel. Said regulating mechanism can utilize action of mounting plate to make the intermediate shaft position be changed relatively to first drive wheel and second drive wheel so as to attain the goal of regulating belt tightness.

Description

technical field [0001] The invention relates to a belt-driven belt tightness adjustment mechanism, in particular to a two-stage belt-driven belt tightness adjustment mechanism and its application on miter saws or table saws. Background technique [0002] Belt transmission is widely used in various mechanical fields. The tightness of the belt in belt transmission directly affects the efficiency and life of the transmission. Therefore, it is very important to maintain effective tension of the belt in belt transmission to ensure that the belt does not slip and Ensure that the belt does not produce "tooth creep" during high-speed operation. [0003] There are many devices to maintain the effective tension of the belt, the most common is that one or more idler pulleys are biased against the inside or outside of the belt to induce tension, and between the idler pulley and the bracket of the device using the pulley system A spring is provided which exerts a constant force on the i...
