A roller pinion system is a linear drive approach that combines the best features of ball screws, rack and pinion, belt drives and linear motors while eliminating many of their short comings. To meet the goals of designing machines and equipment that are faster, more precise, and require less maintenance, commonly chosen options include ball ...
MILL PINION. The pinion and the counter shaft are integral forged and heat treated of high quality steel. For mill power exceeding about 2500 kW two pinions are used, one on each side of the mill (double-drive). The pinion is supported on two spherical roller bearings.
Low speed, high torque, reversible hydraulic motors are employed as direct drives for the rolls or spindles of hot rolling two high reversing mills. The use of these motors is cheaper in capital cost and speeds up the reversing time from 2.5 sec. for electric motor drives to 0.5 sec. The mills are used in steel mills, etc.
of the inching reducer drive can be added to reflect efficiency losses. P inch = P inch ·(1 + (stage · 0.01)) where stage is the number of reductions between the inching drive motor and the main drive input shaft (or mill pinion if direct driven) Round up P inch to the next standard motor power. This standard motor power becomes the incher ...
The requirements for the mechanical devices and the power grid have become more demanding. Controlled soft starting and operation, especially in dual pinion mills, as well as the protection of the equipment has gained importance. The selection of the drive solution for the mill therefore becomes more critical.

Case Study: Mill Drive Train Misalignment. A recent case study involved a grinding mill drive train in a gold mine consisting of a motor, a three-shaft reduction gearbox, two pinion bearings and a pinion gear. All bearings were rolling element types with the mill drive pinion gear bearings being double row spherical roller bearings.

Approximately 10% less Power Consumption. Approximately 10% more production. In case of anti-friction bearing type mills, power bills can be reduced by a further 20%.
Pinion stands are mechanical gearboxes that are used to transfer the torque from a motor or gear reducer with one shaft, to the rolls in a rolling mill where the rolls are individually driven. The pinion stand must have two output shafts for a two high mill, or one with two rolls and three output shafts for three high mills. Pinion stands have ...
Dual pinion high-speed mill drive (with gearbox) and dual-pinion low-speed mill drive (without gearbox). By using the latest generation medium voltage frequency converter drives of ABB as shown in figure 2, with exclusive DTC (direct torque control) technology, these demands can not only be reached, but even exceeded.

differential gear drive is produced, the output speed of one shaft being dependent on the other. Rack-and-pinion gears — A straight bar with teeth cut straight across it, Fig-ure 5, is called a rack. Basically, this rack is considered to be a spur gear unrolled and laid out fiat. Thus, the rack-and-pinion is a special case of spur gearing ...
•Rack and pinion gears are used to convert rotation (From the pinion) into linear motion (of the rack) •A perfect example of this is the steering system on many cars .

Elastic mill sag by weight of mill balls and materia! to grind A: After temporary alignment of the teeth of pinion and girth gear with the mill empty, Fig. 8a, re-alignment should be undertaken with the mill filled with mill balls, i. e. with reference to the elastic sag in cold con- dition, Fig. 8b.
move the motor toward the drive machine to the inner end of the adjustment to release tension on the belts. Use a pry bar against the motor base, if needed. The belts should now be quite loose. If the drive has an idler instead of an adjustable motor base, loosen the hold down bolts and swing the idler away from the belts, allowing them to hang ...
Rawhide Racks. The most important feature of the Rawhide Gear is to transmit cushioned power at a lower noise level, work mesh more smoothly and eliminate destructive vibration that is known in all metal gear trains. It won't wear on the gear opposite; rather it will protect it. Most of the rawhide gears are pinion gears; they drive large diameter driven gears, which are expensive …

The main motor is connected to one side of the gear unit, while the auxiliary drive is connected to the other side. The pinion at the mill's girth gear can be connected via a double-jointed coupling with spacer to ensure the adjustability of the pinion. Single pinion drives are supplied in both fixed and self-aligning design.
speed (mill speed 0.10 rpm). On a large dual pinion mill, using the ABB drive to rotate the mill for maintenance is an advantage over an inching drive, because the inching torque is transmitted by the dual drive system to the mill through both motors and both pinions simultaneously. When an inching drive is used, all of the
An inching drive is used as an auxiliary system to the main drive for a large machine such as a ball mill, industrial kiln, conveyor, or elevator. Its purpose is to turn the equipment at a speed slower than the normal operating speed — typically 1 to 2 rpm, although fractional rpms are also common — and to do so at high torque — typically ...
