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.
Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction. Also available are bearings of the …
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 ...
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 ...
As a result, SIEFLEX ®-HT spindles pack up to double the torque of conventional gear-type drive shafts. To facilitate work roll shifting, SIEFLEX ®-HT spindles include longer internal toothings of the sleeves on the mill pinion side. They achieve shifting distances of more than +/- 200 mm and deflection angles of up to 3°.

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.
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 …
•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 . Special Gears: Bevel and Crown Gears • There's a class of gears designed to transfer motion from one axle to another axle perpendicular to it, ...
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.
We designed and manufactured the first Cracker in 1981 and set up a complete Crumbing/Reclamation plant in 1983. We have developed the most efficient, user-friendly, extra heavy-duty Crackers & Grinders mills of India in the DOUBLE BULL GEAR DRIVE Models.

V-belt driven mills are furnished with an outboard bearing of similar construction. Also available are bearings of the double rigid ring oiling type for special applications. Such bearings are cast integral with a heavy twin bearing sole plate assuring perfect alignment and rigidity. These bearings are equipped with bronze or babbitted bushings.
Each pinion stand has a gearbox, also with helical gears, that splits the power between upper and lower mill rolls. As Figure 2 shows, the gears are huge. Pinions range from 2 …
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.
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 ...
twin pinion drive systems. Early attempts to provide load sharing on ... Spur gears with double meshing pinions drives are not preferred for large mill drives as a single helical gear has more than ... an equivalent gear drive grinding mill. The cast heads are heavier with a longer flange to hold the segmented poles. The total weight of the
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
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.
