Abstract

The invention discloses an interlocking tooth synchronous belt pulley component with reversal no-clearance drive, which is formed by the connection of a main belt pulley and a belt pulley pair which are provided with pin holes with different dimensions on the same diameter by a pin and a pin sleeve. The main belt pulley pin hole and the pin form an interference fit; the belt pulley pair pin hole and the pin form a clearance fit by the pin sleeve; the end surface where the two belt pulleys are contacted with each other is provided with a ring trough which is internally provided with a torsion spring; one end of the torsion spring hooks the main belt pulley pore and the other end thereof hooks the belt pulley pair pore so as to form the interlocking tooth synchronous belt pulley. The interlocking tooth synchronous belt pulley is engaged with a normal synchronous belt so as to compensate the side clearance between the belt and the gear which is caused by factors such as manufacture and installation, etc., thus ensuring the reversal transmission without clearance, improving the transmission precision of the synchronous belt transmission system and carrying out transverse position limit to the synchronous belt which can adjust the reversal instant driving torque by replacing the fixed position of the pin hole and changing the deformation degree of the torsion spring. The interlocking tooth synchronous belt pulley is suitable for long distance synchronous belt engagement transmission which achieves high motion precision by reversal driving torque.

Description

technical field [0001] The invention relates to a synchronous belt pulley, in particular to a long-distance transmission reverse non-backlash driven staggered-tooth synchronous belt pulley. Background technique [0002] Synchronous belt transmission is a transmission device that combines the advantages of chain, gear and triangular belt, and it can achieve high precision in general occasions. However, due to errors in manufacturing and installation, there is still a certain backlash between the teeth on the pulley and the teeth on the belt that cannot be eliminated. It will directly affect the precision of reverse transmission. Contents of the invention [0003] The purpose of the present invention is to provide a backlash-free reverse gear synchronous pulley assembly, through the meshing of the synchronous pulley and the common synchronous belt, the gear backlash can be eliminated, and the backlash-free transmission can be realized. [0004] The technical solution adopt...
