The rubber synchronous belt shaft and the toothed belt wheel are connected by a key on the cone sleeve, so that the ground shaft cannot be rotated and adjusted by the synchronous belt. Every time the repair is carried out, only the 2 ground shaft bearing seats are removed, and the crane is used to lift the height, then the synchronous belt can be idled to adjust the horns to the same angle, and the bearing seat bolts are tightened. Due to the small lifting space of the rear axle of the ground shaft, the bearing seat fixing hole often breaks down, which is time-consuming and laborious; and the cone sleeve structure is a round nut locking structure, which is easy to loosen during operation, and the ground shaft transmission shaft and the cone sleeve are frictional and cause failure. Since each time the bow belt is twisted, the angle of the horn is different, so the horn must be universally adjustable when installing a new bow belt. Rubber synchronous belt transmission is a transmission technology that has developed rapidly in recent years in the world. It has the advantages of belt transmission, chain transmission and gear transmission. It has been widely used in textile, automobile, tobacco, light industry, machine tool and other industries {1t1. Cable arranging is an important process in the production of synchronous belts. The size and uniformity of the arrangement density of the wire rope have a great influence on the product quality indicators such as the tensile strength and fatigue life of the synchronous belt. Stable quality Izl. Therefore, the size and uniformity of the arrangement density of the wire rope is an important technical parameter in the production equipment of the transmission belt and an important indicator to measure the advancedness of the production equipment.
