Housing Rigid, robust and torsion resistant in quality close grained Grey Cast Iron to make sure proper radiation against high temperature generated when models 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 temperature treated and finished to high precision tolerance by grinding procedure, thus avoiding leakage of 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 ideal for rotation in either path, working in and functional check run is done in direction of 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 used for forced-feed lubrication.
Cooling Additional cooling systems provided inside lower component of housing based on power to be transmitted and ambient heat range.
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
Some of the standard structure crane duty helical gearbox features include:
Finding use in Cranes & Hoists, these can be offered in range from 2 HP to 100 HP as per the specific process needs of the customers. Further, the superior Equipment tooth geometry design also allows era of maximum efficiency which includes –
