Chain 12,421 Items
Description: Chains are drives designed with endless links that mesh with sprockets locked to shafts of the powering driver. Because the links of the chain mesh with the sprocket teeth, the setting helps to provide positive speed ratio between the driver and driven sprockets.The main use cases of chains include transmitting power, timing motion, converting rotary motion and conveying materials. Chains in the market primarily fall into two groups. One category is the straight link chains that have alternative inside and outside links. Two, there is also the offset link chains that have all links alike. They include integral link chains like the welded steel chains and flat-top chains. Other specific categories of chains include: 1. Roller chains: These are rollers designed with the primary purpose of reducing friction. However, they also help to engage the sprocket teeth to easily transfer the sliding action. In addition, the chains can help to support a chain as well as the materials being moved on the tracks. 2. Leaf chains: These chains are mainly used for lifting and counterbalancing activities. They are designed to provide high tension but at lower speeds. The chains are good in withstanding normal working load from carrying materials, absorbing shock from both the moving materials and surfaces. 3. The silent chains: The silent chains are designed with toothed link plates assembled on joint components to allow free flexing between pitches. They are made up of stacked rows of flat plates that have gear-type contours to engage sprocket teeth in the same way a rack engages a gear. 4. Engineering steel chains: These chains were first created in 1880 with the primary goal being to deliver more strength, faster speed, and better shock resistance. They are designed with larger clearance between moving parts than the roller chain of the same size so that debris and dirt can easily pass without being pressed to the bearing area. 5. The flat top chains: Like the engineering steel chains, the flat top models are mainly used in conveyors. They comprise a series of top plates that feature hinge-like barrels curled on either side. Then, pins are fitted through barrels to create joints and retained by a press fit. The joints allow straight running chains on a single plane while the barrels mesh with teeth of the sprockets to run the conveyor.
