Subol mechanical design includes spur gears, helical gears, bevel gears, worm gears, and planetary gears.

• Spur gears have straight teeth and are used for low-speed applications.

• Helical gears have angled teeth and are used for high-speed applications.

• Bevel gears have angled teeth and are used for changing the direction of power transmission.

• Worm gears have a screw-like structure and are used for high reduction ratios.

Types of pumps include centrifugal, positive displacement, and axial flow.

• Centrifugal pumps use a rotating impeller to create a flow of fluid.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the system.

• Axial flow pumps use propellers to create a flow of fluid parallel to the axis of the pump.

• Other types of pumps include diaphragm, peristaltic, and gear pumps.

There are two main types of compressors: positive displacement and dynamic.

• Positive displacement compressors work by trapping a fixed amount of air and then compressing it.

• Dynamic compressors work by imparting velocity to the air and then converting that velocity into pressure.

• Examples of positive displacement compressors include reciprocating, rotary screw, and rotary vane compressors.

• Examples of dynamic compressors i
