Abstract

The invention provides a high-reliability tensioning wheel with an asymmetric damping structure. The high-reliability tensioning wheel with an asymmetric damping structure aims to solve the technicalproblem that a belt in the prior art is low in tension and uneven in tension. The high-reliability tensioning wheel with the asymmetric damping structure comprises a supporting sleeve, a first supporting plate, a second supporting plate, a center shaft sleeve, a double-row deep groove ball bearing, a spring, a cover plate, a first belt pulley and a second belt pulley. According to the high-reliability tensioning wheel with the asymmetric damping structure, one end of the spring is connected with the cover plate and fixed to a fixing part supporting sleeve, the other end of the spring is connected with the supporting plates to guarantee rotation, and therefore the requirement that the tensioning wheel provides torque is met, and the double-row deep groove ball bearing is adopted, so that stable and uniform tension on the belt is ensured.

Description

technical field [0001] The invention relates to a high-reliability tension wheel with an asymmetrical damping structure. Background technique [0002] At present, V-belt belts are more and more widely used in the front-end wheel train of the engine, but the belt transmission is a friction transmission, and the belt will gradually extend and wear as time goes on. In order to ensure that the engine can transmit energy to each front-end attachment stably, efficiently and reliably, and to ensure that the belt tension changes in a relatively stable area, a tensioning device (tensioner pulley) is added to the front-end gear train attachment. The traditional fixed tensioning device cannot automatically compensate due to the extension of the belt. When the belt tension is insufficient, the transmission system of the accessory belt will have problems such as low transmission efficiency and high noise. Therefore, an automatic tensioning wheel has been developed. As the belt gradually ...
