Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to ensure proper radiation against warmth generated when products 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 created from medium carbon steel that is duly warmth treated and finished to high precision tolerance by grinding process, thus stopping leakage of oil and entry of dirt.
Bearings Antifriction bearings used to make sure long crane duty helical gearbox service life and also high process efficiency.
Direction of rotation Though gearboxes are suitable for rotation in either direction, running in and functional check run is done in direction of rotation specified.
Lubrication For normal speeds, splash lubrication is provided. At places where splash lubrication isn’t effective, a built-in/individual mounted lubrication oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling systems provided inside lower component of housing based on power to end up being transmitted and ambient heat.
Overhung Loads Bearings may withstand overhung loads that occur because of mounting of toned and V-belt pulleys, gear wheels and chain sprockets of appropriate dimensions.
Painting Casting areas painted with linear epoxy primer (both internally and externally).
High load carrying capacity
Minimal noise generation
Some of the standard construction features include:
Finding use in Cranes & Hoists, these can be offered in range between 2 HP to 100 HP as per the specific process requirements of the clients. Further, the superior Gear tooth geometry design also allows generation of maximum efficiency which includes –
These gearboxes also provide ease of servicing in addition to rigid, robust and torsion resistant housing in order to ensure long services life standards. The housing is made of quality close grained Grey Cast Iron that is proportioned to ensure proper radiation of temperature generated when the systems are operated at maximum capacity. Further, suitable ribs are placed under bearing seats for high power with walls of enough thickness to withstand the majority of severe stresses faced during operation. Further, we also hold experience in providing casing in cast metal/fabricated steel finish if required.
