Timing belts can be divided into various types based on material and structure:
Rubber timing belts: Made of neoprene rubber or hydrogenated nitrile rubber, with internal glass fiber or steel cord reinforcement. They are oil-resistant, wear-resistant, suitable for medium load and speed, and commonly used in automobiles, textile machinery, household appliances, etc.
Polyurethane timing belts: Internally reinforced with steel wire or Kevlar, wear-resistant, oil-resistant, and chemically resistant. Suitable for high-load, high-speed equipment, such as automation equipment, food processing machinery, and packaging equipment.
Open-ended timing belts: Can be cut to the required length and are suitable for linear drives, elevators, conveyors, etc.
Endless timing belts: Ensure transmission synchronization and stability, suitable for transmission systems, machine tools, printing machines, etc.
Double-sided timing belts: Teeth on both sides can transmit power on both sides simultaneously, suitable for multi-axis drive systems.
Classified by tooth profile specifications: Common models include MXL, XL, L, H, XH, XXH, etc. Industrial robots commonly use R3M, R5M, R8M models.
