What is gears
- What is ⚙️gears ?.. Gear is a toothed wheel which is used to transmit constant velocity ratio. Between two shafts which has small distance between their axis of rotation. Types of ⚙️gears According to their axis of rotation (a) Axis of rotation parallel to each other 1 spur gear Tooth is parallel to there axis of shaf 2 . Helical ⚙️gears? Tooth is included at an angle with respect to their shaft axis. There is a drawback that axial force come at Axis of shaft. But running is very smooth 3.Double helical⚙️ gears or haringbone ⚙️gears Tooth are inclined both sides at an angle Which is known as helix angle So axial force is avoided in this type gearing (b) axis of rotation perpendicular to each other and intersecting 1.bevel ⚙️gears They transmits constant velocity ratio At 90° to each other They can transfer constant velocity ratio at Axactly ...
