It is possible to hold the screw shaft even if power failed due to effectiveness of Self-locking feature and safety design features of using trapezoid screw jack. Standardized the capacity of 1/4 ton- 100 ton for wide variety of application. Lubrication of reducer part is grease.
Structure and Feature:
1. Screw shaft end: Many selection of connecter
2. High precision, large screw shaft: Trapezoid screw
3. Ideal bearing structure: Using tapered roller bearing that can hold both radial and thrust load
4. High precision worm wheel: Special aluminum bronze material, high precision cut, sufficient strength
5. Large input shaft: Sufficient strength for connection of multiple jacks
6. Screw shaft guide: Screw shaft guide is provided on the worm wheel and cover to prevent fluctuation of screw.
7. Grease lubrication: Easy maintenance
8. Light weight housing: Housing of fabricated by aluminum and ductile cast iron, light weight and compact.
9. High efficiency speed reducer: Design with benefit of experience in manufacturing of speed reducer.
It consist of worm gear and screw jack (30 degree trapezoid screw), suitable for special heavy load, and have sufficient holding force. Worm wheel (nut) rotate by turning input shaft and that transmit rotating force into the thrust of screw shaft. The lubrication of screw shaft is grease.
