Product Description:
NOSEN R&D, production & sales a new Europe-type Worm Gear Screw Jacks, Cubical Type, small&compact
appearance, installation sizes is the same as Europe famous brand screw jack suppliers like Zimm, Pfaff-silberblau, Grob GmbH, Inkoma, Servomech, Unimec, Thomson Linear etc.
Model: RNF016, RNF018, RNF020, RNF030, RNF040, RNF055, RNF060, RNF070, RNF080, RNF100, RNF120.
Used wherever precisely controlled lifting, lowering, pushing, pulling and rolling movements are required in an efficient and reliable operation. They can be flexibly configured, either being installed as single units, in pairs or multiple jacks systems and can be driven by electric or manually, fully synchronization.
Speed of Travel
* Fast Speed N
1 turn 1 mm travel
1500 mm/min
* Low Speed L
1 turn 0.25 mm travel
375 mm/min
Tolerance & Backlash
Trapezoidal-type screw axial backlash 0.15 mm, radial backlash 0.2 mm, lifting screw outer diameter and sleeve diameter free backlash 0.2 mm. Ball screw backlash depends on different accuracy rated.
Worm shaft&worm gear play, high speed(N), worm shaft backlash ± 3 degrees, Low speed(L), ± 5 degrees.
Lateral Force
Usually, screw jack only loads lift screw axial loading, don't permit to load any lateral force. Any lateral force will reduce screw jack working life, even damage screw jack. We suggest, lateral forces that may occur should be taken by an external guide rail.
Self-locking Function
RNF Series Trapezoidal type screw is of self-locking. The self-locking function depends on a variety of parameters: Large pitches, Different gear ratios, Lubrication, Friction parameters, Ambient influences( such as high or low temperatures), vibrations and mounting position.
Ball screw with large pitches are consequently not self-locking. Suitable brakes or braking motors must therefore be considered in such cases. Limited self-locking can be assumed for smaller pitches (single-start).
Anti-rotation Devices
Single screw jack application, isn't guided and without any guide rails, lifting screw does not do linear motions, only rotation, especially light loading. If that is the case, need to extra add anti-rotation devices. RNF-series screw jack anti-rotation devices, matches with protetive tube.
Stop Collar
Prevents the screw from being removed from the jack gearbox. Following clients requirement, we fit stop collar for screw jacks. The stop collar cannot be used as a fixed stop.
Accessory:
Bevel gearboxes, hand wheel, electric motor, travel nut, protetive tube, rubber bellows, limited switches, couplings, linking shaft, trunnion base etc.
Application Industries:
Precision lift table, Roll forming machines, Press machines, Tunnel Freezer, Surface-Gringing machines, Satellite dish antenna, Solar tracking system, Sluice gate, Theatre stage, Slitting line, Precision leveler, Powered straightener, Paper machines, Food processing machines, Textiles machines etc.
