Housing, flanges and feet are made out of aluminium alloy upto size 090 and for sizes 110 and above cast iron is used.

Worm shafts are made of steel and are case hardened to 58-60 HRC and profile ground. The thread grinding in the gear ratios that the module value permits is carried out with ZI-Profile. This improves the contact between the toothed surfaces and therefore performance and reduces operating noise.

The worm wheel has a G20 cast irn hub onto which a casting in AB1 Bronze RIM is fitted. To guarantee long life, ball bearings of reputed make used.

Lubrication of Gearboxes

Gearboxes are supplied filled with synthetic oil grade ISO VG 320 which is virtually maintenance free and does not require oil change

The type PFC fluid coupling when used in conjunction with a fixed-speed motor will give the motor a light-load start, provide smooth acceleration and ensure overload protection for the motor and driven machine. Using a fluid coupling in the drive-line often makes its possible to employ a smaller motor, because the fluid coupling will allow the motor to run quickly up to speed, where its overload capacity may be used for starting the machine.

Starting or stalling torque may be determined precisely by selection of the initial Oil filling. Further adjustment, to suit drive requirements, may easily be made at site. The type PFC fluid coupling is a compact, rugged unit, the major components being aluminum alloy castings. It comprises the basic fluid coupling, diaphragm input mounting and multidisc, semi-flexible coupling on the output side. Bores and keyways may be finished to suit customer's requirements

Fusible plugs are fitted to all but the smaller fluid couplings to provide protection against excess temperature rise should the motor overload trip fail to operate during stall or overload conditions. Vertical applications can be catered for in most sizes.

Greaves Double Reduction Speed Reducers are two stage worm reduction units. A specially designed primary worm reduction unit is integrally mounted on a standard single reduction Greaves worm reducer which forms the second stage. The composite units provide the most compact and rigid arrangement for large reduction of speed necessary for slow moving machinery. A wide range of ratios upto 4900:1 is available.
