Fig 1.1: Some typical bevel gear The most common gear-cutting processes include hobbing, broaching, milling, and grinding. Gears are commonly made from metal, plastic, and wood. 1.2 Objectives: The main objectives of this project work are- I. To solve a problem related to Bevel Gear II. To design that Bevel Gear III. direction that is parallel to the gear axis of rotation. A spur gear is designed to mesh with another spur gear on a parallel shaft. The profile of the contact surface of spur gear teeth is in the form of an involute curve. An involute curve is the path the end of a string takes when it is being unwound from a cylinder. The shape is the easiest to Gear construction Download PDF Info Prior art keywords shaft wheel gear teeth segments Prior art date 1938-04-05 Legal status (The legal status is an assumption and is not a legal conclusion.

Topic 2 Steering Gear Construction Steering gear, is the equipment provided on ships to Study Resources On spur and gear with one-to-one gear ratio, smallest number of teeth which will not have interference is k =1 for full depth teeth. k = 0.8 for stub teeth On spur meshed with larger gear with gear ratio m G = N G /N P = m, the smallest number of teeth which will not have interference is Gear is an important element of mechanical power transmission. Through various research papers we had learnt the fundamentals of gear which consist of gear terminology, types of gears & use, various gear manufacturing methods, materials of gears, modes of tooth failure, etc. So through various research papers one can choose appropriate gear Gears are produced in enormous amounts—billions of gears are produced by industries every year. While the automotive industry ranks as the primary consumer of gears, numerous other industries also require huge amounts of gears: aerospace (helicopter transmission, etc ), construction machinery, and agricultural machinery, to name a few.

The drawing should be done at 1:1 scale, in mm. Dimension the drawing as shown drawing techniques are based on the construction of basic geometric elements. A point, line, arc, and circle are the basic elements used to create the most complex drawings.
