Advantages of Inverted Tooth Chain

Inverted tooth chains even outscore their alternatives. Whether they are used as a drive solution to replace systems based on gear drives or belts, or as a transport solution in place of belts, roller conveyors, or roller chains – their superiority is demonstrated in measurable advantages.

Advantages of inverted tooth chains at a glance
• Ideal solution for use in drive and transport systems
• High degree of efficiency thanks to low-maintenance operation
• Superior to solutions with toothed wheels/gears or belts (drives)
• Superior to belts, roller conveyors, and roller chains (transport)


Inverted tooth chain drives

Advantages and features of inverted tooth conveyor chains
• Fast, with speeds up to 50 m/s
• Extremely smooth and quiet operation
• Low-maintenance and durable thanks to rolling pivots
• Little lubrication needed
• Toothing without any play

Advantages of Renold Inverted Tooth Chain Drives Over...

... belts
• More resistant to chemicals, especially when cooling lubricants are used
• Simple assembly thanks to the possibilities of pin locks associated with corresponding short downtimes or the lack of extra construction
• Reduced sensitivity to temperatures > 85 °C and extremes in humidity, e.g. material does not swell and the tensile member does not shrink when moisture is absorbed

... other steel pintle chains
• Very high maximum speed
• Low and uniform wear
• Low running noise
• Very high maximum speed
• Low and uniform wear
• Low running noise
• Good meshing conditions
• Low wear even with standard sprockets
• Highly flexible width
• Smooth running , not susceptible to vibration
• High efficiency
• Consistent, high quality

... gear wheels / gear boxes
• Low cost for wide shaft center distances
• Meshing unaffected by fluctuations in temperature
• Quiet at every operating point
• Zero tooth flank backlash
• High tolerances for shaft arrangement
• Possible to combine rotatory and linear motion
• Good self-damping
• Highly efficient at every operating point
• Moderate costs for special solutions
