Synchronous belt What is synchronous belt? Synchronous belt is a wire rope or fiberglass as a strong layer, coated with polyurethane or neoprene ring belt, the belt of the inner week made tooth shape, so that it is meshing with the toothed belt pulley. Synchronous belt transmission, the transmission ratio is accurate, the axial force is small, compact structure, oil-resistant, good abrasion resistance, anti-aging performance, general use temperature-20 ℃-80 ℃, v<50m/s,P<300kw,i<10, for the requirements of synchronous transmission can also be used for low-speed transmission.
Synchronous belt The synchronous belt drive is composed of a circular belt with equal spacing tooth shape on the surface of the inner week and the wheel with corresponding anastomosis.
Synchronous belt It combines the advantages of belt transmission, chain drive and Gear drive. When rotating, the power is transmitted by engaging with the tooth groove of the wheel. Transmission with synchronous belt transmission has accurate transmission ratio, no slip difference, can obtain a constant speed ratio, smooth transmission, can absorb vibration, small noise, the transmission ratio range of large, generally up to 1:10.
Synchronous belt Allow line speeds up to 50M/S, transmitting power from several watts to Baichi. High transmission efficiency, generally up to 98%, compact structure, suitable for multi-axis drive, no lubrication, no pollution, so it can not allow pollution and working environment in a more bad place to work properly.
Synchronous belt Transmission products are widely used in textiles, machine tools, tobacco, telecommunications cables, light industry, chemical industry, metallurgy, instrumentation, food, mines, petroleum, automobiles and other industries of various types of mechanical transmission.
Classification of synchronous Belts:
Synchronous belt teeth have trapezoidal teeth and arc teeth two types, arc tooth has three series: Arc Tooth (H series also known as HTD belt), flat-topped arc teeth (S series also known as STPD bands) and concave-top parabolic teeth (R series).
trapezoid Tooth synchronous Belt
The trapezoidal tooth synchronous belt is divided into two-sided toothed and double teeth, which is called single-sided and double-sided tape. The double-sided tape is divided into symmetrical tooth type (code-named da) and staggered tooth type (code-named DB).
Synchronous belt The trapezoid tooth synchronization has two kinds of size system: Pitch system and modulus system. Our country adopts the pitch system, and according to ISO 5296, the corresponding standard GB/T 11361~11362-1989 and GB/T1616-1989 of synchronous belt drive are developed.
Arc Tooth Synchronous Belt
In addition to the tooth shape of the arc-tooth synchronous belt, the structure of the trapezoidal tooth synchronous belt is basically the same, the pitch of the belt is equal, the tooth height, tooth root thickness and the tooth root round angle radius are bigger than the trapezoidal tooth. With the tooth load, the stress distribution is better, the stress concentration of the tooth root is gentle, and the bearing capacity of the teeth is improved. Therefore, the synchronous belt of the arc tooth is larger than the trapezoidal tooth synchronous belt transmitting power, and can prevent the interference of tooth during meshing.
Arc Tooth Synchronous Belt wear-resisting performance is good, the noise is small, does not need lubrication, can be used in the harsh environment with dust. has been widely used in food, automobiles, textiles, pharmaceuticals, printing, papermaking and other industries.
