The application of timing belt in the field of mechanical automation can be said to be very common, and the timing belt is divided into two types: polyurethane timing belt and rubber timing belt. Today, the small series of XINBEX transmission will introduce the polyurethane timing belt.
The polyurethane PU timing belt is made of imported thermoplastic polyurethane material and has high anti-wear ability. Various types of steel wire cores ensure that they still maintain good motion in the transmission and have small production tolerances. A layer of nylon is applied to the tooth flanks and back of the teeth during production to ensure that the operational specificity is maintained in the particular application. A layer of polyurethane can be added to the back of the belt to prevent corrosion or high loads.
The timing belt drive is composed of a closed annular tape with an equally spaced tooth on the inner peripheral surface and a corresponding pulley. During the movement, the teeth mesh with the tooth grooves of the pulley to transmit motion and power, which is an meshing transmission, and thus has various advantages of gear transmission, chain transmission and belt transmission.
Synchronous belt drive has accurate transmission ratio, no slip, can obtain constant speed ratio, can be precision transmission, stable transmission, shock absorption, low noise, large transmission speed ratio, generally up to 1:10, allowing line speed Up to 50m / s, transmission efficiency is high, generally up to 98% -99%. Transfer power from a few watts to hundreds of kilowatts. The compact structure is also suitable for multi-axis transmission, which has small tension, no lubrication and no pollution, so it can work normally in the case where pollution and working environment are not allowed.
The polyurethane timing belt can be divided into a trapezoidal tooth timing belt and a curved tooth timing belt according to the tooth type. According to the distance between the teeth and the teeth, it can be divided into synchronous belts such as MXL, XL, L, H, 2M, S2M, 3M, S3M, 5M, 8M, 14M, T2.5, T5, AT5, T10, and AT10.
