Right angle worm gear reducer for heavy duty applications
max. 128 000 Nm | AH series
Radicon
The AH worm gear range is offered in 3 basic unit types. Under-driven worm, over-driven worm and vertically mounted with output shaft. The units provide power capacity up to 839 kW in 6 sizes from size 10 to size 24 with worm gear centres from 254mm to 609mm.
All are offered with a choice of 14 standard ratios from 5:1 to 70:1. Motorised versions of all units are also available.
All units are fitted with high capacity taper roller bearings for generous overhung loads, position action oil seals, oil level sight glass and drain holes. Flange mounted units with vertical downshaft have drywells fitted as standard to eliminate a head of oil on the low speed shaft seal and prevent oil leakage. Upper and lower speed shaft bearings are grease lubricated when drywells are fitted. All units can be supplied with holdbacks. Shaft extensions can be supplied with metric or inch dimensions.
Double Reduction Units (worm/worm)
Double reduction worm units are constructed using two single reduction worm gear units connected together. All options of unit type and variant are available in double reduction with standard ratios extended to 4,200:1.
Shaft Mounted Single Reduction Worm Gear Units
Shaft mounted units can be mounted directly on to the driven shaft dispensing with connecting couplings and baseplates along with alignment of the unit and motor. Motorised units are available. Standard and special torque arms are available on request.
