The timing belt is composed of a closed loop tape with an equidistant tooth on the inner peripheral surface and a corresponding pulley. In operation, the teeth are engaged with the cogs of the pulley, which is a meshing drive and thus has the advantages of gear drive, chain drive and belt drive.
Before the timing belt appears, the v band first appears. V-belt V-shaped tape, is a unique conveyor belt, is a transmission force and the transport of goods and equipment. Is a standardized device. Compared with the flat belt, with easy installation, small footprint, high transmission efficiency and low noise, etc., in the entire transmission area occupies an important position. According to the cross-sectional shape and size can be divided into ordinary V-belt, narrow V-belt, wide V belt, ribbed belt, etc .; according to the structure can be divided into cloth-type V-belt and cutting V-belt; Divided into veneer core V-belt and cord V-belt. Mainly used in electric motors and internal combustion engine driven mechanical equipment power transmission.
So what is the reason for the v-band? Before the emergence of v tape, the general use of flat belt to work. But the lack of flat belt is dependent on the friction generated by the belt tension to drive the drum, which makes the application of the servo and positioning when the effect is poor, high tension to bring power transmission lead to shortened life, and sometimes flat belt also Will slip, leading to the inability to play its role.
The traditional V-belt, like a wedge, is embedded in the pulley, which can increase the driving force without requiring a great tension as a flat belt. The pulley and the V-belt contact surface of the pulley are also increased, and the follower is better than the flat belt, and there is no need to worry about the tape deviation.
And then to the back there is a timing belt. Ordinary belt drive has the risk of slipping, in order to avoid the two shaft input and output does not slip must use the timing belt. The timing belt is often a toothed belt, which overcomes the above shortcomings. The timing is provided with a toothed engagement with the groove on the roller.
The profile of the timing belt is generally trapezoidal and has been identified as a standard. This transmission structure is also more used in the processing machinery, textile machinery, warp knitting process and camshaft drive. The timing belt is well suited for efficient control of the Timing Belt Company.
