As synchronous belt drive applications become more widespread, many questions arise regarding the selection and use of timing pulleys and belts. How should we choose timing pulleys? Many purchasers find it difficult to make the right choice. Knowing what to consider when purchasing timing belts and pulleys can make the selection process easier. In general, the selection of timing belts and pulleys is based on the tooth profile and specific engagement parameters required in the synchronous belt transmission system. Let’s delve into the details below.
Selection Method for Timing Belts and Timing Pulleys:
· When selecting a model, start by determining the tooth profile model of the timing belt and timing pulley, as well as relevant engagement parameters such as the pitch of the timing belt. This will help you determine the number of teeth, pitch diameter, and structure of the timing pulley.
· Calculating the number of teeth and diameter of the timing pulley primarily involves first determining the number of teeth on the smaller timing pulley, and then determining the number of teeth on the larger timing pulley based on the transmission ratio of the timing pulley drive system.
· To ensure the longevity of the timing pulleys, the diameter of the smaller timing pulley should be greater than the minimum allowable bending diameter of the timing belt. Then, based on the data, convert it into the minimum number of teeth for the timing pulley. If the structure and cost permit, considering the service life of the timing belt, it is best to have slightly more teeth on the smaller timing pulley than the minimum allowable size.
· When determining the number of teeth on the smaller timing pulley, determine the number of teeth on the larger timing pulley based on the transmission ratio of the timing pulley drive system. Finally, determine the center distance between the two timing pulleys based on the structure of the timing pulley drive.
Storage of Timing Belts and Timing Pulleys:
· When storing timing belts and timing pulleys, avoid direct sunlight and exposure to rain, and store them properly.
· During storage, timing pulleys should be kept away from contact with water, oil, chemicals, heat sources, and other substances.
· When storing, timing belts should not be placed directly on the ground. It is best to hang them on the wall or place them flat on shelves to avoid overcrowding and excessive pressure on the belts, which could cause deformation.
· Avoid folding the belts during storage.
The above information provides guidance on selecting timing belts and timing pulleys and how to store them properly. We hope this is helpful to you.
