Product Description

Gears are Power transmission elements. It is the Gears that decides the torque, speed and direction of rotation of all the driven machine elements. Factors that help in choosing a gear are physical space and shaft arrangement, gear ratio, load, accuracy and quality level. Types of Gears Gear types may be grouped into five major categories. They are Spur, Helical, Bevel, Hypoid, and Worm. 1) Bevel Gears: In these conical shaped gears, the teeth perfectly mesh together. These gears are useful when there is a change required in the direction of the shaft's rotation. These gears can be used in different number of teeth to increase or decrease the rotational speed. Although these gears are generally installed on shafts at a 90¡ angle, they can work well at other angles as well. These gears are also considered very beneficial as they allow adjustments during the assembly stage. 2) Differential Gears: This gear is very commonly used in the automobiles. It links two separate shafts with a covering and tune the total rotational angles of the shafts to that of the covering. These gears are designed in such a manner that when the differential side gear is meshed with the other gear then it produces a high torque, which is transmitted to the axle shaft. There is a set of coaxial gears present in the differential gears. This set includes pinions and turntable. 3) Helical Gears: These are also one of the well-known types of industrial gears. The involute teeth of these gears mesh at an angle to create optimum thrust load. The name helical is due to their teeth, which are curved along a helical path or resemble a helix. Their advanced design enables a smooth operation of these gears. Not only this, they can comfortably carry heavy loads due to the enhanced surface contact with teeth. 4) Spur Gears: Although these gears are simple in operation, they are used in a multitude of industrial and non-industrial applications. They are often found in cylindrical or disk shapes. These gears are used for the purpose of making variations in the force and speed of rotating axles. They possess straight teeth and are usually installed on parallel shafts. They can be used either separately or in a combination of two or more spur gears, depending upon the scope and nature of the application.
