The illustrated sprocket is made of high-quality alloy steel, with the surface quenched to achieve a tooth surface hardness of HRC58-62, providing excellent wear resistance; the wheel body features a "井"-shaped ventilation hole design, which ensures strength while effectively reducing weight and facilitating heat dissipation; the central hole has a keyway and connects to the shaft via a flat key, ensuring efficient and reliable torque transmission. The product precision complies with the GB/T 1243-2006 "Roller Sprocket" standard, operating smoothly with low noise, suitable for continuous long-term operation.
Classification
1. Classification by tooth shape: roller sprocket, toothed sprocket, silent sprocket.
2. Classification by structure: solid sprocket, spoked sprocket, perforated plate sprocket.
3. Classification by use: drive sprocket, conveyor sprocket, tension sprocket.
4. Classification by number of teeth: small-tooth sprocket (Z < 20), medium-tooth sprocket (Z = 20–40), large-tooth sprocket (Z > 40).
Scope of Application
1. Mechanical manufacturing: reducers, machine tools, lifting equipment.
2. Automation equipment: assembly line conveyors, packaging machinery, robot joints.
3. Transportation: automobile manufacturing (engine timing sprockets), rail transit (gearbox drive).
4. Agricultural machinery: harvesters, tractor transmission systems.
5. Chemical and metallurgical industry: mixing equipment, conveyor belt drive devices.
Working Principle
The sprocket transmits motion and power from the driving shaft to the driven shaft through the meshing of the sprocket teeth with the inner plates of the chain. The specific process is:
1. Meshing transmission: when the driving sprocket rotates, its teeth push the inner plates of the chain, driving the chain to move; the chain then meshes with the teeth of the driven sprocket, driving the driven shaft to rotate.
2. Speed conversion: by designing sprockets with different numbers of teeth (e.g., smaller driving sprocket teeth, larger driven sprocket teeth), speed reduction and torque increase can be achieved; conversely, speed increase and torque reduction are possible.
3. Motion transmission: can achieve motion transmission between parallel shafts, intersecting shafts, and skew shafts, and can accommodate certain installation errors.
