The rubber timing belt shaft and the toothed belt wheel are connected by the upper key of the taper sleeve, so that the ground shaft cannot be rotated individually to adjust the horn under the transmission of the timing belt.

In each emergency repair, only the bearing seat of the 2nd axle must be removed, and after the crane is used to lift it up, the synchronous belt can be idling to adjust the horns to the same angle and tighten the bolts of the bearing seat. Due to the small lifting space at the rear of the ground axle, the fixing hole of the bearing seat is often broken, which is time-consuming and labor-intensive; and the cone sleeve structure is a round nut locking structure, which is easy to loose during operation, and the ground axle drive shaft and the cone sleeve rub against each other and cause failure. Since each time the bow belt is twisted, the angle of deviation of the claw's horn is different, so the claw's horn must be able to be adjusted universally when installing a new bow belt.

Rubber timing belt transmission is a kind of transmission technology that has developed rapidly internationally in recent years. It has the advantages of belt transmission, chain transmission and gear transmission. It has been used in textiles, Widely used in automobile, tobacco, light industry, machine tool and other industries.

Wire arranging is an important process in the forming and production of timing belts. The size and uniformity of the cord arrangement density has a great influence on the tensile strength, fatigue life and other product quality indicators of the timing belt. If the cords are evenly arranged, the production The quality of the output belt is stable. Therefore, the size and uniformity of the cord arrangement density is an important technical parameter in the transmission belt production equipment and an important index to measure the advancement of the production equipment.
