Point of contact between two pitch circles. Imaginary circle which would give same motion as actual gears. Manganese molybdenum steel (a)35 Mn 2 Mo 28 Malleable cast iron (a)White heart castings,Ĭarbon manganese steel (a)0.27%carbon (b)0.37%carbon Selection of material plays a very important role in compatibility of geartrain. In case of high gear ratio applications, the size of gearbox is huge, in such cases multiple reduction geartrain is used.

The diameter of pinion depends on the availability of space for the drive train and the selection of material.Īs we all know diameter of driven gear is directly proportional to dia. The diameter of pinion links all the parameters required for designing a drive train. We check the designed for maximum load conditions.

We take an example of a gear train and calculate all the parameters of the gear. In this paper we discuss the parameters that affect the design of a gear pinion and the analysis of the gear. The pinion gear is the driving force for the entire transmission system. KeywordsPinion, spur, bevel, helical and transmission. In this paper we deal with design and analysis of all the gear pinions like spur, helical and bevel pinions. There are several parameters which influence the design of a pinion gear. It is therefore very Important to design a pinion in such a way that it withstands all the designed loads on the transmission system. A pinion is the live gear in the drive train. The power from the source is directly transmitted to pinion by means of shafts, belts or chains etc. Maturi Venkata Subba Rao (MVSR) Engineering College.ĪbstractA Pinion is a ger usually meshed with a driven gear is used for power transmission.
