Gears and gear racks for transmitting torques and forces within gearboxes are typically made of hardened steel.
For many other uses and applications, however, gears and racks of plastic are the better choice. These generally require no lubrication and are cheaper, lighter, quieter and more resistant to corrosion than metal gears. That is why Ganter is expanding its range with polyamide gears and
racks that are capable of transmitting especially high forces and torques.
Gears and racks made from polyamide are preferred in mechanisms that must transmit high torques at low speeds. This includes packaging machines, plants in the chemical and pharmaceutical industries as well as food production. The components are combined such as to convert rotational movements into linear movements or vice versa. Synchronous, symmetrical or even proportional movements can also be easily realized, such as for clamping jaws, grippers or ganged components.
Standard parts specialist Ganter has given thought to the basic principles of gearing and introduced the spur gears GN 7802 and gear racks GN 7822 of strong and long-lasting polyamide. Due to their low coefficients of friction, these require no lubrication, and they are made of FDA-compliant glass fiber-reinforced plastic suitable for use even in food-processing applications. The components
are also available in grey or blue for better visual detectability.
