Casing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against temperature generated when units 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 metal that is duly high temperature treated and finished to high precision tolerance by grinding procedure, thus avoiding leakage of essential oil and entry of dirt.
Bearings Antifriction bearings used to ensure long service life along with 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 normal speeds, splash lubrication is provided. At areas where splash lubrication is not effective, a built-in/separate mounted lubrication essential oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling products provided inside lower component of housing based on power to become 
transmitted and ambient temperature.
Overhung Loads Bearings may withstand overhung loads that occur due to mounting of toned 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
CONSTRUCTION FEATURES
A few of the standard structure features include:
Finding use in Cranes & Hoists, these could be offered in range between 2 HP to 100 HP as per the specific process requirements of the clients. Further, the superior Equipment tooth geometry design also allows era of maximum efficiency which includes –
Sizes
Dimensions
These gearboxes also provide ease of servicing in addition to rigid, robust and torsion resistant housing in order to ensure long service life standards. The casing is constructed of quality close grained Grey Cast Iron that’s proportioned to make sure proper radiation of high temperature generated when the models are operated at maximum capacity. Further, suitable ribs are placed under bearing seats for high power with walls of enough thickness to withstand many severe stresses faced during operation. Further, we also hold knowledge in providing casing in cast steel/fabricated steel finish if required.
