Synchronous pulley, refers to the general steel, aluminum alloy, cast iron, brass and other materials, its inner hole has a round hole, D-shaped hole, tapered hole and other forms. The synchronous pulley drive is composed of a closed annular belt with equidistant teeth on the inner circumferential surface and the corresponding pulley.
Surface treatment has the color of oxidation, black, galvanized, galvanized color, such as high-frequency quenching treatment.The accuracy level depends on customer requirements.

Synchronous pulley features

1, accurate transmission, no sliding when working, with a constant transmission ratio; 2, smooth transmission, with buffering, vibration reduction capacity, low noise; 3, high transmission efficiency, up to 0.98, energy saving effect is obvious; 4, easy maintenance, no lubrication, low maintenance costs; 5, the speed ratio range is large, generally up to 10, the linear speed can reach 50m/s, with a large power transmission range, up to a few watts to hundreds of kilowatts; 6, can be used for long-distance transmission, the center distance can reach more than 10m; 7, no pollution, can not allow pollution and the working environment is more harsh places under normal work.

Timing Pulley Procedure

1, simplify the design: according to the transmission power, input speed, transmission ratio and other conditions of gear transmission, determine the center distance, modulus and other main parameters. If the center distance and modulus are known, this step can be skipped.

2, geometric design calculation: design and calculate the basic parameters of the gear, and calculate the geometric size.

3, strength check: after the basic parameters are determined, accurate tooth surface contact strength and tooth root bending strength check.

Advantages of timing pulley

Synchronous belt according to the material can be divided into neoprene plus fiber rope synchronous belt, polyurethane plus steel wire synchronous belt, according to the shape of the tooth is mainly divided into trapezoidal teeth and circular tooth two categories, according to the arrangement of the tooth surface can be divided into single-sided tooth synchronous belt and double-sided tooth synchronous belt. Synchronous belt drive with accurate transmission ratio, no slip, can obtain a constant speed ratio, precision transmission, smooth transmission, can absorb shock, low noise, transmission ratio range, generally up to 1:10, allowing linear speed up to 50m/s, high transmission efficiency, generally up to 98-99. Transmitting power ranges from a few watts to hundreds of kilowatts. Compact structure and suitable for multi-shaft transmission, small tension, no lubrication, no pollution.
