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