inverted tooth chain for petrochemical industry machinery

Toothed Chain is a specialized transmission chain distinguished by its unique meshing mechanism with sprocket wheel teeth. Unlike traditional chains, toothed chains achieve power transmission through the precise engagement of chain teeth with sprocket teeth, delivering enhanced performance and reliability in demanding applications.

Types & Features

• Externally Meshed Toothed Chain: Outer straight tooth profile on the chain plate meshes with sprocket teeth for stable operation. Notable for larger polygonal effects, increased shock, vibration, and noise.
• Internally Meshed Toothed Chain: Inner toothed profile contacts sprocket teeth, reducing transverse runout, vibration, and ensuring smoother transmission, though with less stable positioning.
• Internally-Externally Meshed Toothed Chain: Combines inner and outer meshing advantages. Ideal for high-speed, variable speed, and variable load conditions. Minimizes polygonal effects, shock, vibration, and noise, while boosting transmission efficiency.

Advantages

• No elastic sliding or slipping—ensures accurate transmission ratio
• Reliable operation and high efficiency
• High power transmission and strong overload capacity
• Compact transmission size and low shaft pressure for given loads
• Operates in high temperature, humidity, dust, and polluted environments
• Small required tension force

Applications

• Chemical industry
• Textile machinery
• Escalators & elevators
• Wood processing
• Three-dimensional parking garages
• Agricultural machinery
• Food processing
• Instrumentation
• Petroleum industry

Limitations

• Usable only between two parallel shafts
• Higher cost and susceptibility to wear and elongation
• Poor transmission smoothness and potential for additional dynamic loads, vibration, shock, and noise
• Not suitable for rapid reversal transmissions

Toothed Chains are widely adopted for mechanical transmission across various industries—offering robust, accurate, and high-efficiency power transfer with specialized designs for diverse operational needs.
