Types of Gear: Spur, Helical, Herring Bone, Worm Gear [Notes & PDF] Different Types of Gear [Notes and PDF] Written by Er. Amrit Kumar in Manufacturing Technology In this article, we will be study different types of gear and those are Spur Gear, Helical Gear, Double Helical and Herring Bone Gear, Crossed Helical Gears, and Worm Gear.

The gear and methods were - types of gears, seasonal variation of gears, types of indigenous fishing devices and fish composition. The fishing gears are classified into several groups for the better study of the same. RESULT OF THE STUDY A diverse range of fishing gears and methods have been evolved over a long period of

Depending on the type of pinion gear with which it is mated, the gear rack's teeth are either parallel (when mated with spur gears) or angled (when mated with 

Gear Types Spur gears Internal gears Most common form Used for parallel shafts Suitable for low to medium speed application Relatively high ratios can be achieved (< 7) Steel, brass, bronze, cast iron, and plastics Can also be made from sheet metal August 15, 2007 10 Gear Parameters Number of teeth Form of teeth Size of teeth

Gear cutting by Shaper process: 3.2.2 Gear cutting by Rack planing process: 3.2.3 Gear cutting in the Sunderland process: 3.2.4 Gear cutting in the Maag process: 3.3.1 Gear Hob process or Gear cutting on a Hob machine: A gear is a vital constituent of machinery.

The present study on fishing craft and gears with their modes of operation in the Manas river reveals that only one type of fishing craft namely the plank boat and nine different types of gears are

fTypes of Gears • Spur Gear • Helical Gear • Bevel Gear • Internal Gear • Worm Gear fSpur Gear • Spur gears have their teeth parallel to axis and are used for transmitting power between two parallel shafts. • They are simple in construction, wasy to manufacture and cost less. • They have highest efficiency and excellent precision rating.
