Timing belt pulley
Pulley design
Overview of timing pulleys: Timing pulleys are generally made of steel, aluminum alloy, cast iron, brass, and other materials. The inner hole has round holes, D-shaped holes, tapered holes and other forms. The surface treatment includes natural oxidation, blackening, galvanizing, galvanizing, and high-frequency hardening. Accuracy level depends on customer requirements.

1. The produced synchronous belt pulley is not only used for the synchronous belt of domestic equipment, but also can be used instead of imported synchronous belt pulley.
2. User-defined synchronous pulley, please provide the drawing of the pulley (the figure does not need to draw the tooth size of the pulley). The pulley can be drawn for the user according to the specifications provided by the user, the inner hole of the pulley, the key slot, and the width. drawing.
3. The synchronous belt wheel can be processed according to the user's requirements. Similarly, our factory can also make drawings for the users.
Features of synchronous belt wheels: (1) Accurate transmission, no slippage at work, and constant transmission ratio; (2) Smooth transmission, buffering, vibration reduction and low noise; (3) High transmission efficiency, up to 0.98, energy saving The effect is obvious; (4) convenient maintenance, no lubrication is required, and low maintenance costs; (5) a wide range of speed ratios, generally up to 10, linear speeds up to 50m / s, and a large power transmission range, up to several Watts to several hundred kilowatts; (6) can be used for long-distance transmission, the center distance can reach more than 10m. (7) No pollution, can work normally in places where pollution is not allowed and the working environment is harsh.
