Radicon Series A gearbox

Radicon Series A gearbox

Single Reduction Units (worm)

This fully metric range of units of 100, 125, 160 and 200 mm centres is based on a single universal case for each size, giving a high degree of common parts and interchangeability. Under-driven, over-driven and vertical types provide a choice of shaft arrangements in meeting the requirements of a wide variety of applications in the medium power range up to 140 kW.

All units are designed with hollow output bore, outputshaft can be fitted allowing handing to be changed without dismantling the unit.

Series A Mid Range gives a choice of 12 standard ratios from 5/1 to 70/1 and important features include high efficiencies and load carrying capacities combined with long life and reliability in service.


Double Reduction Units (worm/worm)

These units consist of a standard single reduction unit with a smaller shaft mounted unit fitted to the input shaft. The three smallest sizes are fitted with shaft mounted Series A Junior units whilst the size 2002 is fitted with a size 1002 (C07 when motorised). The range extends the ratios available up to the maximum of 4200/1 making them ideal for fitting to slow moving machinery (Ratios up to 14900/1 are available in size 2002 motorised. Consult our Application Engineers for details).

As with the single reduction units they are available in under-driven, overdriven and vertical types, foot mounting and shaft mounting.


Heavy Duty Stirrer Units

Based on the standard Series A Mid Range the Heavy Duty Stirrer Unit incorporates an extended bearing housing to accommodate a larger bottom bearing and increased shaft size, thereby enhancing the units capacity to absorb the high bending loads imposed during stirrer applications.

These units can be ordered with a dry-well option to minimise the risk of output shaft leakage.


Cooling Tower Fan Drives

Based on the standard Series A Mid Range the Cooling Tower Fan Drive incorporates an extended top bearing housing to accommodate the larger wheelshaft bearing whilst maintaining a compact drive.

Lengths of output shaft extensions are manufactured to clients requirements to suit fan hubs.

Lubrication is entirely contained. Gears and lower bearings dip in the oil bath whilst oil is pumped to the top wheelshaft bearing by means of a built-in mechanical oil pump.

Two oil seals are fitted on both the wheelshaft and wormshaft, the wheelshaft extension incorporating a grease chamber. All exposed parts other than the extensions are finished with corrosion resistant paint. Units are supplied with BSP plugs fitted to the oil filler, drain and ventilator points, suitable for connection to the outsides of towers. Where specified on the order we can supply the necessary piping complete with ventilator, combined dipstick and oil drain.

When selecting a unit, use the selection procedure as detailed on pages 10 – 11 and apply a service factor of 1.75

Enquiries should include full details of the duty required together with full information regarding ambient temperature at site and whether acids or abrasive solids are likely to be present in the air flow.
