Rotostat Services Interview Questions and Answers

A helical gear will not produce axial thrust but it neutralizes the axial thrust.

• Helical gear is a type of gear with angled teeth that gradually engage, reducing the likelihood of axial thrust

• The angled teeth of a helical gear allow for smoother and quieter operation compared to spur gears

• Examples of vehicles that use helical gears include cars, trucks, and motorcycles

The average power steering gear ratio in general is around 15:1.

• The average power steering gear ratio is typically around 15:1

• This ratio allows for easier steering at low speeds and more stability at high speeds

• Some vehicles may have different gear ratios based on their specific design and intended use

Square cut seals are necessary for preventing leaks and ensuring proper sealing in various components of a four-wheeler.

• Square cut seals provide a more secure and reliable seal compared to O-rings in certain applications.

• They are commonly used in hydraulic systems, engines, and transmissions to prevent fluid leaks.

• Square cut seals are designed to withstand high pressures and temperatures, making them ideal for automotive applications.

• They are available in different materials ...read more

Synchromesh action is needed in a gear box to allow smooth shifting of gears without grinding or clashing.

• Synchromesh action helps match the speed of the gear and the shaft before engagement, reducing wear and tear on the gears.

• It allows for smoother and quieter gear shifts, enhancing the overall driving experience.

• Without synchromesh action, gears would grind or clash during shifting, leading to premature wear and potential damage to the gearbox.

• Examples of vehicles with syn...read more

Hard gear shifting can be caused by issues with the clutch, transmission fluid, or gear synchronizers.

• Worn out clutch components can make it difficult to disengage the clutch fully, leading to hard shifting.

• Low or contaminated transmission fluid can cause increased friction and difficulty in shifting gears smoothly.

• Damaged or worn out gear synchronizers can result in grinding or resistance when shifting gears.

The universal joint connects the propeller shaft.

• Universal joint is used to connect the propeller shaft to the transmission or differential

• It allows for flexibility and movement in the drivetrain

• Common types include single, double, and constant velocity joints
