How is power transmission of a belt drive determined?
In the article Basics of power transmission it was shown with the belt friction equation that the maximum frictional force F f,max between belt and pulley at a given tight side force F t or slack side force F s can be determined with the formulae listed below.
What happens when a belt drive is under load?
The stronger the belt is already under tension in the load-free state by the so-called pre-load, the higher the belt tension will be during operation under load. Since higher belt tensions mean higher frictional forces, higher circumferential forces can be transmitted.
When was the last belt horsepower test conducted?
The last belt horsepower test was conducted in 1959. Just as so many of us love to just look at antique tractors, the practical use of a tractor to power other equipment, or even another tractor, continues today!
Is there a force on the slack side of the belt?
This means that there must always be an acting force on the slack side of the belt to ensure the belt tension and with it the contact pressure. The slack side must therefore not be force-free at all (see also the article Basics of power transmission )!
Where is the power steering drive belt located?
The belt that drives a power-steering hydraulic-fluid pump is usually at the front of the engine , turned by a pulley on the crankshaft . It is generally separate from the belt that drives the water pump and alternator , but it may drive other components as well as the power-steering pump .
Where is the drive belt on a car?
The Video Course teaches you everything about modern cars. The belt that drives a power-steering hydraulic-fluid pump is usually at the front of the engine , turned by a pulley on the crankshaft .
What to do if your power steering belt is too slack?
If the belt was too slack, increase the tension by levering the pump outwards with a strong screwdriver or flat bar. Lever against the cast front end of the pump body, just behind the drive-belt pulley — not against any other part of the body or pipework, which are easily damaged.
How to check the tension on a power steering belt?
To check the tension, lay a straight-edge along the outer edge of the belt. If the belt goes round more than two pulleys, use the longest run of the belt. Use your thumbs to push the belt inwards at its mid point, pushing quite hard.
