①When installing the rubber synchronous belt, if the center distance between the two pulleys can be moved, the center distance of the pulley must be shortened first, and then the center distance should be reset after installing the synchronous belt. ② When installing the timing belt on the pulley, remember not to use excessive force, or use a screwdriver to pry the timing belt hard, to prevent the tensile layer in the timing belt from causing unsightly breakage. When designing the pulley, it is better to choose the structure where the two shafts can move closer to each other. If the structure does not allow it, it is best to install the timing belt and the pulley together on the corresponding shaft. ③ Control proper initial tension. ④In the transmission of rubber synchronous belt, the parallelism of the axis of the two pulleys is relatively high, otherwise the synchronous belt will run out of motion during work, or even jump out of the pulley. Non-parallel axes will cause uneven pressure and early wear of the teeth. ⑤The rack supporting the pulley must have sufficient rigidity, otherwise the two axes will not be parallel when the combination lock is running. The transmission belt is the power generated by the rotation of the motor or engine of the prime mover, and is transmitted to the mechanical equipment through the belt through the belt, so it is also called the power belt. It is the core connecting component of electromechanical equipment, with a wide variety of uses and extremely wide applications. From giant motors as large as several thousand kilowatts to small motors as small as one kilowatt, even including precision machinery such as home appliances, computers, robots, etc., are inseparable from the transmission belt. Its biggest feature is that it can be freely shifted, far and near transmission, simple structure and easy replacement. Therefore, there are transmission belts from the original machinery to modern automatic equipment. The product has undergone many evolutions and the technology has become mature.
