Q:

What are the different types of gearboxes?

A:

Quick Answer

The different types of gearboxes include bevel, helical, spur, worm and planetary. Gearboxes are used to alter the speed of a motor, vary greatly depending on the manufacturers and may be used for low-speed or high-speed applications. They are usually made from materials such as brass, iron and aluminum.

Full Answer

Bevel gearboxes are available in two types: spiral and straight-teeth gears. Straight gears are necessary for applications that need low speeds while spiral gears are required in high-speed applications. They are made from aluminum alloy or cast iron.

Helical gearboxes have different angles to allow contact between the teeth. These gearboxes are known to have a smooth operation, and are commonly used in high horsepower applications.

Spur gearboxes have straight teeth attached to a parallel shaft. The teeth of these gearboxes are known to collide, resulting in wear. They are available in different sizes for use in different speeds of applications.

Known to produce low noise level, worm gearboxes can be used in braking systems. They are usually placed in a locked position when not in use.

Planetary gearboxes are named after the solar system due to their design, which resembles the solar system. They have different parts, including ring gears, planetary gears and a sun gear. The sun gear is placed at the center of the gearbox.

    What is a powertrain control module?

    A:

    Also referred to as an onboard computer, a powertrain control module (PCM) is a powerful computer that helps in managing and controlling emission systems, fuel injection and the ignition system. In some vehicles, the PCM might also be used to manage the anti-lock brake system and an automatic transmission.

  • Q:

    Why are there metal shavings in the transmission fluid?

    A:

    Normal wear of the transmission produces metal shavings in the fluid. While this is not a problem, it indicates it is time to change the fluid, according to AutoZone. Failure to perform this maintenance task according to schedule allows these shavings to increase transmission wear, leading to early failure.

  • Q:

    What could cause a transmission to emit noise?

    A:

    Any squeaks or sounds that are emitted during a transmission are due to electromagnetic interference or EMI. EMI results when an electronic, such as a cell phone, transmits waves in a radio frequency that clashes with another electronic's operation. If a computer signal is strong enough, a phone will mistake the wave as a cell phone transmission.
