Kosova Power Corporation (KPC) is using gear boxes mainly for mining purposes.
There are two main types of gear boxes which are used at open pit mining's and have different functions.
Everyday hard work and bad working conditions are only some factors that make gear boxes to get damaged.
The first preoccupations in the field were materialized through graphical solutions as basis for gear box design taking in consideration the speed range of the spindle and kinematic characteristics of the electric motor [Ispas et al., 1997, Perovic, 1993].
The kinematic structure of the gear box (kinematic variant, step number m) depends on its adjusting capacity.
where [i.sub.a max] = 2/1 and [i.sub.a min] = 1/3 are maximum and minimum transfer ratios of the gear box; [R.sub.nk]--spindle speed variation ratio depending on its speed range arranging mode at P = const.
Showing CX25 25-mm twin-screw compounder and new gear boxes with 20% higher torque.
Manufactures twin-screw extruder components and assemblies, twin-screw side feeders, gear boxes, vent stuffers, fast-lock dies, and screw elements.
(recently acquired by CPM Holding, Waterloo, Iowa), is introducing a new series of gear boxes
with 20% higher torque and 250 bar of operating pressure.
The M1300EP has no chains, but moves platens directly from gear boxes and timing belts with speed precisely controlled from variable two-speed motors.
