Rocker Joint Type Silent Chains (Transfer Case Silent Chains)
Rocker common type silent chain(Transfer Case Silent Chains) is mainly used for four-wheel drive transfer case and gearbox drive system, which is the core component of the drive system. The unique rocker joint pin dual-meshing design makes its structure different from the ordinary round pin type silent chain and thus reducing the polygon effect and noise effectively. This chain has superior performances such as high strength, wear resistance, torque transmission in many conditions, etc.

Round Pin Type Silent Chains
 |
|
Round pin type silent chain is mainly used for transfer case and gearbox assembly drive system, which is the core component of the drive system. The chain is made from superior quality steel, and the plates are austempered, which is especially suitable for various conditions such as high strength, high wear resistance, low noise, ample torque, etc.

Advantages of the Silent Chain
Silent chains offer unique advantages and options in power transmission and conveying applications.
Transfer Case Silent Chains For Power Transmission
Power transmission chains can transmit loads and speeds that exceed the capacity of all other chains and belts. This increased load and speed capability results from the specialized chain and sprocket designs which increase the load carrying capability of the chain and significantly reduce vibration and noise. Such silent chains can transmit up to 3000 HP, with speeds exceeding 7,000FPM and mechanical efficiency of up to 99%.
For Conveying
Silent conveying chains provide a smooth, durable, flat surface with less vibration and velocity variation than other products. Chains are manufactured from hardened steel components, making them long-lasting and tolerant of elevated temperatures. They are available in various standard widths and constructions or can be quickly built to suit a specific application.
Strength, accuracy, speed, silent operation, heat resistance, and durability are the main advantages of the silent chain.
From the food to the automobile industry, a wide range of tooth chains’ application: every industrial environment that needs to transfer and transport products along the production line.
The structure of the silent tooth chain is characterized by double oscillating pins and a particular meshing profile between the chain and the gears, which allow highly uniform and precise sliding.
Due to the geometric coupling between the chain and the gear teeth, the transmission device can ensure that the transmission does not slip and does not need chain pre-tightening. It is an ideal choice for the modern machinery industry, which needs accurate, fast, and efficient transmission.
In addition, high-quality materials and production processes make the chain quiet and wear-resistant, even under the most challenging environmental conditions, such as high temperatures or corrosive chemicals.
