500 kN Capacity Mechanical Lifting Machine Gearbox

Jacton 500 kn capacity mechanical lifting machine gearbox designed for injection molding machines-head adjustment. Available in 14:1 and 56:1 worm gear ratios. There are no standard stroke and all worm gear screw jack systems travel lengths are built with customers required. Available stroke from 60mm to 7500mm.
Features of 500 kN Capacity Mechanical Lifting Machine Gearbox
1. Upright or inverted installation with maximum static load capacity 500 kN in tension or compression.
2. Self-locking with no need brake or lock mechanisms to hold position.
3. 120mm diameter lifting screw, 14mm lead acme screw (single start acme thread).
4. Available in 14:1 and 56:1 ratios.
5. Custom travel lengths from 50mm to 6000mm.
6. Translating screw (travelling screw jacks), keyed screw for anti-rotation, and rotating screw with traveling nut (travelling nut screw jacks) as the standard configurations.
7. Worm screw is rotated by a hand wheel with handle (manual screw jack) or by a electric motor (electric screw jack).
8. Can be applied either individually use or combined into a exactly synchronized lifting system, linked by connecting shafts, bevel gears and couplings etc.
Structures of 500 kN Capacity Mechanical Lifting Machine Gearbox
1. Lifting screw material - C45 steel
2. Worm (input shaft) material - C45 steel
3. Worm gear material - bronze
4. Housing (gearbox) material - ductile iron
5. Traveling nut or Safety nut - bronze
Specifications of 500 kN Capacity Mechanical Lifting Machine Gearbox
The specifications of 500 kn capacity mechanical lifting machine for gear box include maximum load capacity, worm screw diameter and pitch, worm gear ratio, allowable maximum input power, torque and speed and overall efficiency etc.
1. Conditions: 20% running time/60 minutes or 30% running time/10 minutes, 20 °C ambient temperature. Maximum allowable input power 20kw, when your selection is exceed the maximum input power, the operational restrictions due to thermal limits. you will need to choose the bigger size screw jacks in order to allow effective heat dissipation.
2. Nm=input torque required, kW=input power required.
3. H=high ratio 14:1 (1mm stroke for one input turn), L=slow ratio 56:1 (0.25mm stroke for one input turn).
4. Selection of screw jacks using above figures should only be carried out in consultation with Jacton engineers.
