Worm Gear Screw Jacks---Lude Transmission

Screw Jack System Accessories When you need multiple screw jack arrangement, you will need to use some screw jack system accessories. PP: Protective tube (lifting screw dust-proof and rustproof) BB: Bellows boots (lifting screw dust-proof and rustproof) HW: Hand wheel (hand operated) DC: Digital counter or digital position indicator (installed on worm shaft, precision display stroke) EM: Electric motor (motor driven) GR: Gear reducer (motor driven with reduction gearbox) WR: Worm gear reducer (motor driven with worm reduction gearbox) LS: Limit switches (control stroke, when full extend or full retract travel, the motor will stop ) SN: Stop nut (installed at the bottom of lifting screw, prevent lifting screw from being removed from the jack housing) PB: Pillow block bearing (when long distance between the supports, pillow block bearing is recommended) FB: Flange pillow block bearing (when rotating screw jacks with long stroke or unguided, flange pillow block bearing is recommended) ...

The main advantages of   electric worm gear screw jack   are: Higher Performance · Accurate and smooth delivery of force. · Increased range of actuation as the stroke position is easily and quickly varied. · Electro-mechanical solutions are more resistant to temperature variations. · Complete control of the entire motion profile using standard control methods. · Repeatable and accurate positioning. Reduced Costs · The   electro-mechanical screw jack   is generally cheaper when compared to a hydraulic system when the required ancillary hydraulic equipment is included. · Machinery requires less maintenance as no hydraulic oil to maintain, no leaks to repair. · Less manual intervention on machinery to set up processes as electro-mechanical solutions can be controlled over the complete motion profile. · Reduced downtime caused by hazardous fluid leaks. · Electro-mechanical solutions only use pow...
