Urethane helical gears are custom cast from high-quality material to produce a gear that is chemical resistant. Urethane helical gears are manufactured at Plan Tech with speed and precision, they are available in any size or pitch needed for the specific application. In areas with limited space custom helical urethane gears, applications include rack and pinion setups to allow 90-degree output shafts in a small configuration.
Urethane helical gears are also available with tight tolerance requirements to process liquids in a pitch style set up. At Plan Tech we can reverse engineering existing urethane helical gears as well as produce new styles and sizes for custom applications and can incorporate custom key ways if required. In high strength applications, a steel core may be added to increase the load of the urethane helical gears. Common urethane helical gears have the teeth at an angle (19º 31′ 42″) for increased load capacity and quiet operation due to urethanes great ability to have greater physical properties in medium hardness vs traditional steel helical gears. The helical urethane gear style provides several key benefits over the straight gears. Being meshed at an angle allows the gear to operate quieter than the straight cut gears, especially at high speeds Also urethane helical gears also have a higher contact ratio as the number of effective teeth engaged in increased with the angle helical style gears vs straight, which increases the load carrying capacity. In most cases, urethane helical gears cost the same as the straight urethane gears!
For over 30 years we have focused on using speed and precision to manufacture the highest quality industrial cast urethane parts to our customers. A particular strength is the breadth of our in-house capabilities which, when combined with our extensive experience, enables us to deliver tight tolerance cast polyurethane parts while maintaining the quality control and cost effectiveness our customers require. The tests are performed according to an established set of standards provided by an accredited testing organization such as the (Society for Testing and Materials ASTM) who define the procedures in detail.
