Description

High-strength low-noise agricultural light V belt

Technical Field

The utility model relates to a drive belt technical field, concretely relates to agricultural light-duty V area of high strength low noise.

Background

The belt transmission is one of the important transmission forms of mechanical transmission, and the belt transmission utilizes the friction or the engagement between a transmission belt tensioned on a belt wheel and the belt wheel to transmit motion and power during working, so that the belt transmission has a wide application range and various transmission forms. The V belt is one of transmission belts and is suitable for power transmission with small center distance and large transmission ratio; the V-belt is a driving belt without joints, so that the transmission is stable, and the V-belt is widely applied to mechanical transmission.

With the national emphasis on agricultural mechanization, various agricultural machinery equipment is developed rapidly, and an agricultural machinery V belt is a main transmission part of the agricultural machinery equipment. When the V-belt type power transmission device is used, the V-belt is sleeved on the belt wheels on the driving side and the driven side, and the two side surfaces of the V-belt and the side surfaces of the wheel grooves of the belt wheels are pressed tightly to generate friction force to transmit power; the V-belt has a large contact area with the pulley, and is subject to repeated alternating stress and to multiple actions such as bending, torsion, fatigue, abrasion, and the like. However, the agricultural machine V belt on the market at present has low strength, small transverse tension and poor bending resistance and flexibility, and is difficult to bear reverse flex fatigue in use. Therefore, when the existing agricultural machine V belt is used on agricultural machine equipment for a long time, the belt body of the agricultural machine V belt is cracked or even broken due to abrasion, the service life of the V belt is shortened, and elastic sliding can be caused between the V belt and the belt wheel, so that the transmission ratio between the V belt and the belt wheel is inaccurate, and the production efficiency of the agricultural machine equipment is influenced.
