What is the belt next to the engine?
serpentine belt
The serpentine belt is one long, snaking, winding belt that keeps your alternator, power steering pump, air conditioning and—in some cases—your water pump running smoothly and effectively.
What do you call the belt that drives the engine?
A drive belt is the part that drives all these accessories. The belt itself is driven by a pulley attached to the engine crankshaft. Most cars have one or two drive belts. When a car has only one drive belt, it might be called a serpentine belt.
How is the motion of a belt drive transmitted?
A belt drive is shown in the figure. It consists of two pulleys over which an endless belt it passed over them. The mechanical power or rotary motion is transmitted from the driving pulley to the driven pulley because of the frictional grip that exists between the belt and the pulley surface.
What happens when you change your drive belt?
Also, if your car has hydraulic power steering, you will lose the steering assist, as the power steering pump will be disabled. In addition, the alternator will stop supplying electric power that is needed to recharge the car battery and run the vehicle electric systems. Old vs new drive belt. See larger photo.
What kind of belt drive has three pulleys?
A stepped cone pulley is an integral casting having three or number of pulleys of different sizes one adjacent to the other as shown in fig. One set of stepped cone pulley is mounted in reverse on the driven shaft. An endless belt will be wrapped around one pair of pulleys.
Why are belt drives used in electric motors?
There are more than a few belt-driven electric motors in use today: Approximately one-third of the electric motors in the industrial and commercial sectors use belt drives.1 And V-belts are powerful tools. Belt drives provide flexibility in the positioning of the motor relative to the load.
Why are accessory drive belts called V-belts?
Automotive accessory drive belts mounted visibly outside the engine are also known as “V-belts” because their trapezoidal shape tapers from wide to narrow as it forms a V point near the bottom.
Is it OK to install different belts on the same motor?
Belts should always be installed in matched sets, and never install belts from different manufacturers on the same motor. Otherwise, the belts may have different stretch characteristics and coefficients of friction and may not have the same load-carrying ability.
What should I do when replacing my V-belt?
When replacing V-belts, maintenance professionals must verify that the replacements are the correct size. The belt should ride in the groove with its top flat surface level with the outer edge of the sheave. Belts should always be installed in matched sets, and never install belts from different manufacturers on the same motor.
