Types of Gear and Their Features
Types of Gear Types and Their Features
Here are 25 types of gears with brief descriptions of their features:
1.Spur Gears: Simplest and most common type of gear, with straight teeth that are parallel to the axis of rotation.
2.Helical Gears: Similar to spur gears, but with teeth that are angled or helical, which makes them quieter and smoother in operation.
3.Double Helical Gears: Also known as herringbone gears, they have two sets of teeth that are angled in opposite directions to cancel out axial forces.
4.Bevel Gears: Used to transmit power and motion between shafts that are at an angle to each other, with cone-shaped teeth.
5.Hypoid Gears: Similar to bevel gears, but with non-intersecting axes, which allows for a larger gear ratio.
6.Worm Gears: Consist of a worm gear and worm wheel, used for high reduction ratios and a right-angle drive.
7.Rack and Pinion Gears: Used to convert rotational motion into linear motion, with a linear rack and a circular pinion.
8.Spur Rack Gears: Straight-toothed gears that are linear in shape and used for linear motion.
9.Internal Gears: Similar to spur gears but with teeth on the inside, used for planetary gear systems.
10.Planetary Gears: Consist of a central sun gear, planet gears, and a ring gear, used for high torque and compact design.
11.Epicyclic Gears: Similar to planetary gears, but with more complex motion paths and greater flexibility in design.
12.Straight Bevel Gears: Similar to bevel gears, but with teeth that are straight rather than curved.
13.Spiral Bevel Gears: Similar to straight bevel gears, but with angled teeth for smoother operation and greater load capacity.
14.Zerol Bevel Gears: A type of spiral bevel gear with teeth that are curved in both the axial and radial directions.
15.Crown Gears: Used in differential systems, with cylindrical teeth that are perpendicular to the axis of rotation.
16.Face Gears: Similar to crown gears, but with teeth that are flat and perpendicular to the axis of rotation.
17.Skew Bevel Gears: A type of bevel gear with teeth that are angled in both the axial and radial directions.
18.Hypocycloid Gears: A type of planetary gear that has a smaller diameter than the sun gear.
19.Cycloid Gears: Similar to hypocycloid gears, but with a more complex shape and greater flexibility in design.
20.Spiroid Gears: A type of spiral bevel gear with a more complex tooth shape and greater load capacity.
21.Coniflex Gears: Similar to spiral bevel gears, but with a different tooth shape that allows for smoother operation and greater load capacity.
22.Involute Gears: A type of spur gear with teeth that have a specific profile shape for smoother operation.
23.Quick-Change Gears: Used in machine tools for quick and easy gear changes.
24.Variable Speed Gears: Used to vary the speed of a machine or device, with adjustable gear ratios.
25.Continuously Variable Transmissions (CVTs): Use a belt or chain that can vary in width to achieve an infinite number of gear ratios.
