What are the basic gear terminologies?

What are the basic gear terminologies?

Basic Gear Terminology Face Width is the length of the teeth in the axial direction. Outside Diameter (O.D.) is the diameter of a circle around the outer surface, or tops of the gear teeth. Pitch Diameter (P.D.) is the diameter of the pitch circle. Pitch Circle.

What is gear and its classification?

Gears are classified into 3 categories; parallel axes gears, intersecting axes gears, and nonparallel and nonintersecting axes gears. Spur gears and helical gears are parallel axes gears. Bevel gears are intersecting axes gears. Screw or crossed helical, worm gear and hypoid gears belong to the third category.

What is gear and its type?

Different Types and Applications of Gears

Type of Gear Application
Bevel Gear Pumps Power plants Material handling systems Aerospace and aircraft Railways and trains Automobiles
Helical Gear Similar to spur gears but with greater loads and higher speeds. Automobiles (transmission systems)

What is gear & Types?

There are many types of gears such as spur gears, helical gears, bevel gears, worm gears, gear rack, etc. These can be broadly classified by looking at the positions of axes such as parallel shafts, intersecting shafts and non-intersecting shafts.

What are the three types of gears?

There are three gear axes configurations: parallel, intersecting, and non-parallel/ non-intersecting. Gears with parallel axes resided parallel to each other, one shaft rotating in the opposite direction of the other. Gears with intersecting axes intersect on the same plan.

What is gear and its function?

Gears are used to transfer motion and torque between machine components in mechanical devices. Depending on the design and construction of the gear pair employed, gears can change the direction of movement and/or increase the output speed or torque.

What are 3 types of gear systems?

Different Types of Gears and Uses

  • Spur gears.
  • Helical gears.
  • Bevel gears.
  • Worm gears.
  • Rack and pinion.

What is a gear tooth called?

PINION is a machine part with gear teeth. When two gears run together, the one with the smaller number of teeth is called the pinion.

What is gear terminology?

“Gear terminology” refers to all definitions used to define a gear or the terminologies needed to make a gear. The most common definitions are as follows: The outer surface of a hypothetical friction wheel that acts as a reference surface for setting the gear teeth is known as a “pitch surface” in gear terminology.

What is the working surface of a gear called?

Flank: The working surface of a gear tooth, located between the pitch diameter and the bottom of the teeth Wheel: Larger of the two meshing gears is called wheel. Pinion: The smaller of the two meshing gears is called pinion. Land: The top surface of the tooth.

What are the basic gear technology?

Basic Gear Terminology and Calculation / Let’s learn the basics of Basic Gear Technology ! 1 Comparative Size of Gear-Teeth. 2 Pressure Angle ( α ) Pressure angle is the leaning angle of a gear tooth, an element determining the tooth profile. 3 Number of teeth. 4 Tooth Depth and Thickness.

What is the module of gear?

The module of gear is inverse of the diametric pitch. Mathematically it is equal to the ratio of pitch circle diameter and number of teeth. Gears with the equal module can only mate with each other. It is the width of the tooth at pitch circle diameter.
