Markets/Application
Suitable for numerous specifications that can be widely used in synchronous driven area.
Timing belt drive consists of an endless belt whose inner surface has equally spaced teeth and of wheels that have the corresponding teeth and is a kind of new type belt drive which has synthesized all the good points of belt drive, chain drive, and gear drive while working, the teeth of the belt and the gullets of the gear joggle each other to transmit the motion and the drnamic force.
Timing belt drive has such features as exact transmission ratio, non-sliding, constant velocity ratio, even motion, absorption of vibration, little noise, the big range of transmission ratio which can normally reach 1:10, and the linear velocity can reach 40m/s. The high transmission efficiency normally reaches 0.98, compacting structure, the suitability to multi-axis transmission, no need of lubrication, no pollution and so on. Therefore, the product can normally work well in the places where no pollution is allowed and where the working condition is worse and can be widely used in machinery drives, such industry as automobiles, machine tools, textile, chemical engineering, light industry, mining, instruments, oil industry and so on as well as all kinds of other machinery Drive.
Timing belt we produced have a lot of advantages: anti-wearing out, low elongation rate and high strength, resistant to temperature range, nonaning, ozone resistant, etc All these can meet customers request perfectly, the property of our belts have reached or surpassed the international standard.
Product Description:
1, Economic and free-maintenance to replace traditional driven model will be an idel chofce.
2, Precisely moulded teeth profiles, nylon fabric cover protects the tooth surfaces.
3, Wide range of load capacities and speed ratios. Constant angular velocity.
Efficiencies up to 99%. Maintenance-free continuity of operation.
In terms of tooth profile, timing belt can be divided into tapezoidal profile and arctooth profile.in terms of tooth arrangements, timing belt can be divided into single-sided belt and double side belt. In terms of tooth pitch, timing belt can be divided into different sizes.
