1) Spur Gear -Parallel and co-planer shafts connected by gears are called spur gears. The arrangement is called spur gearing. Spur gears have straight teeth and are parallel to the axis of the wheel. Spur gears are the most common type of gears.

Spur Gear Types And Tooth Form. The most general type of spur gear is the spur gears which has a solid hub. These spur gears are generally used in transmissions of machineries. Shaft is assembled inside the hole that is bored to this hub. Also keyways are machined on this hole for the assembly of keys. You can find a small screw hole on spur gears.

So the train value of simple gear train is: n1/n2/=T1/T2. It may be noted that when the number od intermediate gear is odd the motion of both the driver gear and driven gear have the same direction of motion, but when the number of driver gear and driven gear even then we see the opposite direction of motion between driver and driven gears.

Some of the types of gears which employ parallel configurations include spur gears, helical gears, internal gears, and some variants of rack and pinion gears.

Types of bevel gears are classified according to their geometry of the total design. But now, we should clearly explain what a bevel gear 

Internal gear mechanisms are of three types: planetary, solar, and star. Depending on the application and other pertinent factors, a variety of 

Roughly speaking, gearboxes are divided into four types: gear drives, belt drives, chain drives and friction wheel drive. 1 Introduction2 Gear drive3 Belt drive and chain drive4 Friction wheel drive Introduction Transmission are available in many different types, depending on the application, e.g. as gear drive, belt drive, friction drive, worm drive, planetary drive, etc. []

Gear Types Gear Types Crab Pots The crab pot is the most commonly used method of harvesting crabs on the Chesapeake Bay. The crab pot is a square trap constructed out of galvanized wire and has two internal chambers. The lower chamber can consist of two or four entrance ways, which allow the crab to enter but not exit.

These are used in shaft couplings which are of gear types and planetary gear drives. One limitation in this type of gears is the difference between a number of external and internal gears which occurs due to trimming problems and interference such as trochoid and involute. Mitre gear. Mitre gears are one type of bevel gears with speed ratio 1

4/1 · There are the following types of gears on the basis of type of gearing: External Gear. Internal Gear. Rack and Pinion Gear. External and internal gears are cut in the slotting machine. These gears can also be made into milling machines through milling cutters. These types of gears are described below.

Internal gear mechanisms are of three types: planetary, solar, and star. Depending on the application and other pertinent factors, a variety of speed transmission ratios may be produced along with the desired rotational direction. Internal gears are employed in a variety of industries where they are commonly used as reduction gears.
