PMMI PREVIEW - V-belt Drives Quiz - Part 2

What is the operation of a notched v-belt?

• Increases the risk of slippage and power loss
• Provides better flexibility and grip for efficient power transmission
• Reduces the lifespan of the belt due to excessive wear
• Causes overheating and potential damage to the machinery

how does a variable speed v-belt system work?

• By adjusting the distance between the two pulleys using a variable pitch pulley on one of them.
• By adding more pulleys to the system
• By changing the material of the belt
• By increasing the tension of the belt

What is a variable pitch pulley?

• A variable pitch pulley is a type of exotic fruit
• A variable pitch pulley is a type of musical instrument
• A variable pitch pulley is used for baking bread
• A variable pitch pulley is a pulley system where the pitch diameter can be adjusted to change the speed ratio between the input and output shafts.

what is the function of a v-belt idler pulley?

• Generate power for the v-belt
• Control the speed of the v-belt
• Increase the lifespan of the v-belt
• Provide tension to the v-belt

what industrial application would we use a v-belt idler pulley?

• Cooling a room
• Maintaining tension in a v-belt system
• Generating electricity
• Transporting liquids

In most cases, where should an idler pulley be mounted?

• On the slack side of the drive pulley

• Next to the drive pulley
• On top of the drive pulley
• Inside the drive pulley

how do you specify a v-belt?

• Look at the belt manufacturer, belt price, and belt warranty.
• Consider the belt type, belt width, belt length, and the number of ribs.
• Consider the belt color, belt material, and belt thickness.
• Check the belt flexibility, belt weight, and belt temperature resistance.

what are v-belt match codes used for?

• Identifying the correct replacement belt for a specific application
• Tracking the number of hours worked by employees
• Determining the best fishing spots
• Calculating the distance between two cities

How is a sheave specified?

• By specifying its length, texture, and brand.
• By specifying its temperature, taste, and smell.
• By specifying its color, weight, and shape.
• By specifying its diameter, width, and material type.

one example of preventative maintenance on a v-belt drive?

• Using the v-belt at maximum load capacity
• Replacing the v-belt only when it breaks
• Spraying water on the v-belt for lubrication
• Regularly inspecting and adjusting the tension of the v-belt.
