Correct option is D
The
rack and pinion gear system is specifically designed to convert rotary motion into linear motion or vice versa. It consists of two components:
·
Rack: A linear gear (straight bar with teeth).
·
Pinion: A circular gear that engages with the rack. When the pinion rotates, it moves the rack linearly, or vice versa.
Applications of Rack and Pinion:
· Steering systems in automobiles.
· CNC machines for precise linear motion.
· Industrial machinery for lifting or sliding operations.
Advantages:
· Simple and efficient mechanism.
· Provides precise control of linear motion.
· Durable under high loads when properly maintained.
Bevel gears are used to transmit motion between shafts at various angles to each other.
The
hypoid gears are used is automobile differential gear boxes.
Spiral bevel gear are designed for application that require high speed and high torque power.
