→Design
QYJ series gear units are a completely new design. Advantages are
•More sizes with a reduced variety of parts;
• Higher operational reliability combined with increased power capacity ;
• Predominantly non-contacting wear-resistant labyrinth seals are possible;
• Flanged output shafts to facilitate assembly of gear units in confined spaces(on request).
→Mounting Position
• OYN series gear units can be supplied for either horizontal or vertical installation
• Other arrangements are also possible on request.
• The basic gear unit can be optimally adapted to the customer
requirements by fitting different add-on pieces like motor bell housings, gear unit swing bases, or backstops
→Noise Behavior
Now concepts were applied to clearly improve the noise emission of the gear units by
• Grinding the bevel gears,
- Designing noise-absorbing housings by means of the computing program
• Achieving exceptionally large contact ratios.
→Thermal Conduction
QYJ series gear units not only have a high efficiency but also a favorable thermal conduction
• Through enlarged housing surface areas
• Because non-contacting labyrinth seals can be used
• Because large fans incorporating a new type of air conduction fan cowl are being used.
•The selection of QYJ series gear units is based on a low maximum oil temperature. By that, the operational reliability will be increased and the cost of maintenance reduced due to longer oil change intervals
→Storing
Gear units have been designed according to a new unit constructor principle.
