Gear boxes with Pinion Stand for Wire Rod Mill Drives
The recent trend for such mill stands is to go alternatively for
one horizontal and one vertical set which avoids 90 stock rotation at
the end of each reduction and accordingly the gear boxes have the drive
arrangement and the shaft disposition. ELECON made a mark by developing
such type of special gear boxes first time in the country as import
substitution and supplied to M/S Mukund Ltd and saved sizable amount
of foreign exchange.
The set of these gear boxes consist of total 14 No,7
horizontal and 7 vertical, having higher ratio in the beginning and
tapering into lower ratio at the tail end. The size varies from SCF
710 / 480 at the bigger end to KAF 315 / 285 at the small end. All the
gear internals are out of case carburising steel duly carburised and
hardened and precisely ground with profile corrections on all pinions
and longitudinal corrections depending on the load, so as to keep the
noise level as low as upto 80 db. Forging ratios for the gear internals
are specially monitored as well special care is taken in the sealing
arrangement. All the bearings as well almost all gear meshing are spray
lubricated which are getting adequate supply of lubricating oil from
common force lubrication system.
