EOT Crane Gear Box

EOT Crane Gear Box

Gear Boxes is main part of any crane & are responsible for the performance reliability. The gear units use HARDENED & 15 HELICAL GEARS in R 20 & 15 series running silent oil bath and vibration free steel fabricated stress relieved housing. The gear unit have long life and are almost maintenance free. The weight/power ratio is optimised by the use of case hardened low carbon alloy steels of high strength (58-62 HRC). The gear reduction efficiency obtained is as high as 99% per reduction.

SPECIFICATIONS


Description

JEC Make Helical gear boxes one built on modular Concept of construction confirming to is standards with respect to sizes, dimensions. This Provides economic mass production, Comprehensive Maintenance of delivery period and easy of servicing.

Gears and pinions

The gears are generated with highest Accuracy on hobbing Machine. The material for the pinion and Gear wheel are made of hard wearing special steel of graded strength to meet the individual load conditions. The selection of module, footh profile, and material is made in conformity with speeds, ration, and load conditions to give maximum tooth contact and overlap, thus ensuring most favorable meshing and soundless running.

Housing

Rigid, Robust, Torsion resistant Housing are fabricated to dampen vibration and resist the heat Max.

Bearings

Anti-friction bearings of ample size are used throughout to ensure long service life. The use of antifriction bearings ensure high efficiency, correct centre distance and proper shaft alignment. Shaft extensions are fitted with high quality seals to prevent oil leakage and dust entry.
