Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against heat generated when products are operated at their maximum capacity
Helical Gears & Pinion Shafts These have involute profile teeth and are constructed using high alloy case hardening steel.
Shafts Low speed shafts created from medium carbon metal that is duly heat treated and finished to high precision tolerance by grinding process, thus stopping leakage of oil and entry of dirt.
Bearings Antifriction bearings used to ensure long service life and also high process efficiency.
Path of rotation Though gearboxes are ideal for rotation in either path, running in and functional test run is done in direction of rotation specified.
Lubrication For regular speeds, splash lubrication is provided. At places where splash lubrication is not effective, a built-in/individual mounted lubrication oil pump is used for forced-feed lubrication.
Cooling Additional cooling systems provided inside lower component of housing based on power to end up being transmitted and ambient temperatures.
Overhung Loads Bearings may withstand overhung loads that arise due to mounting of smooth and V-belt pulleys, gear wheels and chain sprockets of appropriate dimensions.
Painting Casting surfaces painted with linear epoxy primer (both internally and externally).
High load carrying capacity
Minimal noise generation
CONSTRUCTION FEATURES
A few of the standard structure features include:
Finding make use of in Cranes & Hoists, these can be offered in range from 2 HP to 100 HP according to the specific process needs of the customers. Further, the superior Gear tooth geometry design also allows generation of maximum efficiency which includes –
Sizes
Dimensions
These gearboxes also provide ease of servicing and also rigid, robust 
and torsion resistant housing so as to ensure long assistance life standards. The casing is made from quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of warmth generated when the models are operated at maximum capacity. Further, ideal ribs are positioned under bearing seats for high power with walls of enough thickness to withstand many severe stresses faced during operation. Further, we also hold expertise in providing casing in cast metal/fabricated steel complete if required.
