High performance Intech Power-Core non-lubricated gears and rollers contribute to the development of new processing technologies for which traditional metal components no longer are considered because of weight, noise wear and the need for lubrication that may contaminate products.

Product contamination with lubricants and the low momentum of inertia are concerns in, for example, a gear drive for a diaper-making machine that must withstand high torque transmission and shock load during high speed, stop-and-go operation. Using Intech Power-Core gears with large aluminum hubs, engineers were able to satisfy all the tough design criteria, including the elimination of heat build up in the gearing from high torque transmission. The use of aluminum hubs reduced both the gear’s inertia and operating temperature through heat dissipation. With a special tooth modification to reduce tooth root stress and friction on the tooth flanks, engineers calculated a minimum of three years of useful gear life.

Intech Power-Core rollers, applying special snap-in construction, replace metal cam followers and plain bearings in high-load, precision applications in, for example, clean-room conveyors. Operating without lubrication, Intech Power-Core rollers reduce noise, are highly resistant to developing permanent flats, do not wear out the rail and the composite tire retains its tight fit around the bearing throughout load and temperature fluctuations. They do not swell in moisture and retain their toughness in dry or frosty conditions, making them suitable for out-of-doors applications.

Engineering calculations and design assistance help assure the long and useful life of Intech Power-Core gears and rollers.

Intech will participate in the National Design and Engineering Show and Conference in Chicago, March 5 to 8, booth no 6774.
