Timing belt wheel design method tooth profile and timing belt wheel hob, purpose: to study and analyze the structure of trapezoidal tooth synchronous belt wheel, arc tooth synchronous belt wheel, what effect does it have on the transmission, and what is the tooth profile of Qilong synchronous belt wheel Design, design of hob and calculation formula of tooth profile of synchronous belt wheel.
The key points of the problem: the tooth profile of the synchronous belt wheel, the tooth profile of the hob of the synchronous belt wheel, the design of the synchronous belt wheel, and the calculation and analysis of the synchronous belt wheel.
Timing belt wheels and, including some older machinery, are changing the original V-belt drive to the current timing belt with timing belt wheels for transmission. Internationally, inch timing belt wheels with timing belts are generally used. Transmission, and our country generally adopts the analog-digital system synchronous belt transmission. At present, engineers basically refer to international standards when selecting models. The national standard modular synchronous belt has not been promoted well in the country. The rate is not high. Most of the timing belt pulleys and timing belt processing plants do not have modular tools and molds. The currently more popular types of teeth include STPD-type high-torque timing pulleys and AT-type synchronization. Pulleys, HTD-type full-circle-tooth synchronous belt wheels, and RPP-type synchronous belt wheels that are more commonly used in manipulators.
When designing and installing the synchronous pulley, be careful of the following aspects:
1. When the timing belt is running, the parallelism of the axis of the two pulleys should be appropriate, otherwise the timing belt will run off when it is running, and it will jump out of the pulley in severe cases.
2. The rigidity of the frame used to support the pulley must meet the requirements, otherwise the two axes will not be parallel when the pulley is working.
