Product Description

Here is the introduction to sprockets translated into English:
 
Introduction to Sprockets
 
- Basic Concept
A sprocket is a toothed wheel with embedded chain teeth, designed to mesh with pitch-accurate links or blocks on a chain or cable. It transmits power through the chain to the driven wheel, achieving mechanical drive.
- Structural Design
- Tooth Profile
The commonly used end face tooth profile of sprockets is composed of three arcs and one straight line, referred to as the "three-arc-straight line" tooth profile. This profile ensures smooth engagement and disengagement of chain links and is easy to machine.
- Structure
Small-diameter sprockets are typically made as a single piece, medium-diameter ones are often hub-plate type, and large-diameter sprockets can be combined, with the ring and core made of different materials.
- Material
Sprocket materials must ensure sufficient tooth strength and wear resistance, commonly including carbon steel, alloy steel, stainless steel, engineering plastics, etc.
- Working Principle
Relying on the meshing of teeth and chain links, the driving sprocket pulls the chain when rotating, and the chain drives the driven sprocket to transfer the circular motion of the driving sprocket to the driven one, achieving motion and power transmission. It also transfers the driving force from the driving sprocket to the driven sprocket to drive connected components.
- Features
- Advantages
- Transmits motion and power over long center distances between two shafts.
- Operates in harsh environments (low speed, heavy load, high temperature, dusty conditions, etc.).
- Compared with belt drives, it has no elastic sliding, maintaining an accurate average transmission ratio.
- Transmits large power with high efficiency (generally 0.95-0.97).
- Chains require less tension, resulting in low loads on shafts and bearings.
- Disadvantages
- The polygon effect causes speed fluctuations during chain meshing.
- Sprockets with fewer teeth have larger tooth angles, increasing contact stress between the chain and tooth surface, leading to louder operation.
- Wear of sprockets and chains affects transmission accuracy and efficiency.
- Application Fields
Widely used in industries such as chemical engineering, textile machinery, escalators, wood processing, stereo parking garages, agricultural machinery, food processing, instruments, and petroleum. It also plays a key role in the engine and transmission systems of the automotive industry, as well as power transmission in motorcycles and bicycles.
