Non-equal-arm-length two-way automatic tensioning wheel

Abstract

The invention discloses a non-equal-arm-length two-way automatic tensioning wheel. The non-equal-arm-length two-way automatic tensioning wheel is formed by assembling a base, a one-way automatic tensioning wheel assembly, a rocker arm assembly, a sliding bearing, a damping piece I, a damping piece II, an auxiliary spring holder, an auxiliary spring and a cover plate; the end of the base is connected with a front shell of an intelligent motor, the sliding bearing is arranged on the center column face of the base through a key groove, the sliding bearing is sequentially sleeved with the auxiliary spring holder, the damping piece I, the rocker arm assembly and the damping piece II, the auxiliary spring is located in the auxiliary spring holder, and the base of the one-way automatic tensioningwheel assembly and a rocker arm of the rocker arm assembly are integrated. The non-equal-arm-length two-way automatic tensioning wheel has the beneficial effects that the structure is simple and compact, and the function can be flexibly adjusted. In the applying and matching process, the high flexibility is achieved, design needs of various projects can be met, and meanwhile, cost is low.

Description

technical field [0001] The invention belongs to the technical field of transmission components, and in particular relates to a bidirectional automatic tensioner with unequal arm length. Background technique [0002] The two-way tensioner is an automatic tensioning device designed to synchronously tension the belt on both sides of the motor pulley in the wheel train design of the accessory belt-driven intelligent motor. During the working process of the smart motor, when it acts as a motor and as a generator, the belt tension on both sides of the motor pulley will change greatly. In order to reduce the excessive belt tension change at the moment of switching working conditions, no matter the left arm or the right arm of the two-way tensioner, even the whole body can move freely relative to the base. Therefore, the complex movement of the two-way tensioner is powered by the unbalanced belt tension on both sides of the motor pulley, so as to ensure that the belt tension will n...

Problems solved by technology

However, the function of its products depends too much on the design of the corresponding gear train layout. For example, the spring of the product is very simple. If the designer needs to adjust the application tension of the belt, it can only be realized by changing the gear train layout. The damping design of the product It is also too limited, and its damping also depends on the direction of the belt in the layout, that is, the wrap angle of the belt on the pulley

Such a design has brought great restrictions to the application work of designers and customers

At the same time, its product structure is too complex and the cost is too high
