Worm Geared SE Enclosed Small Slew Drive With Quenched Gear Tooth For Construction Machinery
Worm Geared SE Enclosed Slew Drive With Quenched Gear Tooth, High Axial Load For Construction Machinery
Description
SE series is an enclosed housing slew drive with IP66 enclosure protection level. It is designed with an hourglass worm shaft with 5 teeth in contact between the slew ring and the worm shaft. This design offers a very solid back holding torque capacity for the heavy loads. Mining industry, cement industry and many more industries with high contamination of fine particle environment prefer this drive for its tightness. It is also the choice for most of outdoor installations subjected to heavy rain and snow as it is well sealed compared to other designs.
Application
Worm drives have proven effective in many machines and equipment, in various applications and various operational conditions, such as: construction and assembly platforms, placement of cockpits in forest machinery, material handling equipment, positioning of solar systems, control of superstructures and operational applications of construction machinery, industrial cranes and so on.
Advantages
1. Use skeleton oil seal to avoid oil leakage efficiently
2. The mounting dimension designed could match many applications.
3. Easy maintenance
4. Adopt worm gear structure which has strong adhesion and driving torque
