| Bevel Gear Machine Screw Jacks are by the use of spiral bevel gears mechanism with self locking trapezoidal screws. These bevel gear jacks use bevel gears inside the housing instead of worm gearing. Bevel gears are more efficient than worm gearing—around 35% compared to 20%. So these bevel gear jacks offer higher efficiency and greater speed than other mechanical worm gear screw jacks, but a bit more expensive. As an added benefit, bevel gear jacks with three shafts also act as 90 degree bevel gearboxes, making them an ideal choice for multiple screw jack lift systems, which helps balance the difference in price. | |||||||||

Product Description
Bevel Gear Machine Screw Jack 1000kg-24x4-Trapezoidal Screw. Bevel gear screw jacks are made with spiral bevel reduction gears and trapezoidal acme screws, available in both rotating and travelling versions. The high performance actuators are also made with spiral bevel reduction gears and trapezoidal acme screws. In the absence of vibration load, they are self-locking and precisely position loads, will hold loads without backdriving, and no need any brake mechanism or locking system. For low duty cycle applications, for hand-operated applications, or if back driving is not acceptable consider a bevel gear machine screw jack.
Main Features
* Equipped with hardened spiral toothed bevel gear transmissions for high lifting speeds, greater duty cycles, high efficiency and long lifespan.
* One, two and three drive shafts configurations are available.
* Maximum static load capacity 1000 kg. Maximum dynamic load capacity 300 kg.
* Self-locking trapezoidal screw sizes Tr 24x4, precise positioning, and uniform speed.
* Reduction gear ratio: 2.5:1. Travel 1.6 mm per turn of input shaft.
* Custom stroke length, maximum stroke 1000 mm in compression load, 1500 mm in tension load.
* Basic designs: Translating screw, Anti-rotation screw, and Rotating screw.
* Upright or Inverted mounting. Available in tension or compression loads.
* Standard with 1-start thread screw, custom 2-starts threads screw which offers increased travel speed and require a brake or external locking device to hold position.
* Screw end fittings: top plate, clevis end, threaded end, plain end, fork head and rod end.
* Power source: manual handwheel, electric motor drive, or both together.
* Can be applied either individually use or combined into a exactly synchronized lifting system(multiple jack systems), linked by connecting shafts, bevel gearboxes, couplings, electric motors, gear reducers, limit switches and pillow blocks etc.
* Optimal for low-speed operation: The driving system has less noise because machinery can be driven at a lower input speed.
* Higher efficiency, higher lifting speed, higher duty cycle, longer lifespan.
* Simple and effective solution in comparison with hydraulic and pneumatic systems.
