Since both the pinion and gear are made of the same material (i.e. cast steel), therefore the pinion is weaker. Thus the design will be based upon the pinion. We know that the torque transmitted by the pinion, T = (60P) / (2πN) = 14.32 N-m. Tangential tooth load on the pinion, W T = T / (Dp/2) We know that number of teeth on the pinion,

In SECTION 5, we have discussed the standard tooth thickness s1 and s2. In the meshing of a pair of gears, if the tooth thickness of pinion and gear were reduced by Δs1 and Δs2, they would produce a backlash of Δs1 and Δs2 in the direction of the pitch circle. Let the magnitude of Δs1 and Δs2 be 0.1., We know that a = 20 degrees, then :
Raymond mill, roller mill). The different types of feed system and corresponding wear liners allow the installation of FCB TSV™ Classifier in a wide range of process configurations. In a ball mill plant, FCB TSV™ Classifier can be either: — Integrated into the mill venting system for total or semi-airswept mills
A flexible coupling connects two shafts, end-to-end in the same line, for two main purposes. The first is to transmit power (torque) from one shaft to the other, causing both to rotate in unison, at the same RPM. The second is to compensate for minor amounts of misalignment and random movement between the two shafts.

A pinion is a round gear used in several applications: The pinion gear range consists of metric pitches from module 1.0 to 40, in various styles including helical, straight (spur), ISO flanged, split-pinion and circular pitch. Quality levels available include soft, induction-hardened and hardened & ground (up to AGMA 12+ and DIN 5).
The roller shaft is an important item of sugar mill equipment and being subject to heavy loading it must be made to high standard of quality. 1) Shaft Material- 45C8 (C - 0.35-0.45 %, Mn - 0.60 to 0.90%), as per the standard IS: 1570-1979.
A pinion, with integral shaft, weighs 10,000 to 20,000 lb. The gears range from 5 to 15-ft pitch diameter and 2 to 5-ft face width. A typical …
Torque on the pinion. The torque on the pinion is simply the tangential force (force on the rack) multiplied by the pinion radius. Tp = torque on pinion (Nm, ft-lb) rp = pinion radius (m, ft) Remember to divide the pinion diameter by 2 to get the radius, and by 1000 to convert from mm to m (or by 12 to convert from inches to feet).
All tapered roller bearings to DIN 720, ISO 355 and integral tapered roller bearings have the tolerance class Normal to ISO 492:2014. In contrast to the standard, X-life bearings achieve improved radial runout values t Kia and t Kea, in addition to …
AGMA Fine Pitch Tolerances for Gears Gear tolerance chart below, lists the more common tolerance or quality specifications assigned for Spur, Helical and Herringbone type gears. AGMA Spur Gear Bending Stress Equation and Spread Sheet (1999) The AGMA* spur gear bending method can be viewed as a detailed refinement of the Lewis method.

Thus, The AGMA Bending Geometry Factor J is determined from Table 12-9 for a pinion by relating the number of pinion teeth (20) to the number of gear teeth (56) This value is different when analyzing Gears 2, 4, and 6 The Face Width F is chosen as the minimum in the suitable range in order to get the best values for safety factors for this gear.
The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
HOT STRIP MILL — HIGHEST PERFORMANCE FOR NEW AND EXISTING STEEL MILLS The demand for hot rolled strip is growing in multiple ways. To remain competitive, new and existing mills must meet this challenge in the best possible way. The production of hot strip is a key element of steel production.

Working Principle of Rolling Process: The rolling process is a metal forming process, in which stock of the material is passed between one or more pairs of rollers in order to reduce and to maintain the uniform thickness. This process is mainly focused on the cross-section of the ingot or the metal which is forming.
