Features The hallmark of the ALLROYD "SM" series worm gear reducers is its well known quality and reliability and its ability in meeting the needs of industries worldwide. This is achieved by the most effective combination of the very best in engineering design, highest quality material and excellence in manufacturing. All our ALLROYD "SM" series worm gear reducers bore testimony to our commitment for excellence and boost of such inherent features. Compact High efficiency High thermal capacity Strength and resistance to shock Long Life Unrivalled economy High torque capacity Smooth operation without trouble

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. The wormshafts are made of high quality case hardening steeL accurately generated, ground and superfinished. The wormwheels comprise of phosphor bronze centrifugally cast rims of substantial sections welded to rigid centres. Considerable flexibility of shaft layout is permissible with all types of Double Reduction units. The dimension drawing for each series shows the different shaft handing arrangements and the appropriate reference should always be quoted when ordering.

Premium 'AL' series greaves gearboxes are manufactured with high quality material and modern design in order to guarantee the maximum reliability and life. 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

Elign Gear Couplings consists of hubs with multi crowned teeth at Flank, tip and chamfering on teeth. Specification :   Flanks of the teeth are crowned so that tooth thickness is greatest at that centre of the tooth.   Crowned Tips :   Tips of teeth are crowned. The crowned tip contacts the root of internal gear teeth in the external sleeve, accurately piloting the sleeve with true concentric ball-and-socket action.   Gear Case   Gear case is of streamlined design, rugged in construction, made of close-grain cast iron.   Crowned Chamfers : Faces of the teeth adjacent to the tips are chamfered to eliminate interference with the sleeve tooth fillets.
