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 in 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 steel that is duly heat treated and finished to high precision tolerance by grinding procedure, thus preventing leakage of essential oil and entry of dust.
Bearings Antifriction bearings used to ensure long service life in addition to high process efficiency.
Direction of rotation Though gearboxes are ideal for rotation in either direction, 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 oil pump is utilized for forced-feed lubrication.
Cooling Additional cooling products provided inside lower part of housing based on power to be transmitted and ambient temp.
Overhung Loads Bearings can withstand overhung loads that occur 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
A few of the standard construction crane duty helical gearbox 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 clients. Further, the superior Gear tooth geometry style also allows era of maximum efficiency that includes –
