How do you pick a V belt for a pulley?
The following minimum information is required to allow selection of the correct V-belt system parts:-
- Speed (rpm) of drive and driven shafts.
- Motor power (HP or KW)
- Type of “prime mover” or motor and starting style for electric motors.
- Shaft diameter of drive and driven shafts (inch or metric)
What is V belt pitch diameter?
The diameter that is formed on the sheave by the pitch line of the belt is the sheave’s pitch diameter. A belt’s pitch line typically corresponds to the location of its internal tensile cord. But improvements in belt construction have moved the tensile cord to a location higher in the belt.
How do you read V-belt size?
Automotive belts start with either 4L (12.5mm wide) or 3L (9.5mm). The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2″ less for a 4L belt, and 1-1/2″ less for a 3L belt. An example would be 4L460, which would be 46″ long outside, 44″ inside.
How Do You measure V belt size?
Use a cloth measuring tape (not a steel one) and wrap it around the outside of the belt. You also use a thin string to take this measurement and place it on a steel tape to get the correct length. Next, for “A” Belts (1/2” width) subtract two-inches from the outside measurement to select the correct V-belt.
What is pulley pitch diameter?
pitch diameter: Diameter of the pulley at the pitch line level of the belt used with this pulley. Cp. 3.1.2.9. pitch circumference: Circumference of a circle with a diameter equal to the pitch diameter.
How do you size a pulley belt?
How to calculate a belt length?
- First, determine the diameter of the larger pulley. Measure the diameter of the larger pulley.
- Next, determine the diameter of the smaller pulley. Measure the diameter of the smaller pully.
- Next, measure the distance between pulleys.
- Finally, calculate the belt length.
What is the difference V belts 4L vs B belt?
4L series (light duty), A series (standard duty). The AX series is a higher. horsepower rated belt then either of the other 2. The cogged part grips. the smaller pulley better and throws off heat buildup better also. a B series is a different width and thickness and the length conversion is slightly different.
What size is a V belt?
V-Belt Type: Top Width: Height: Angle: A: 1/2″ 5/16″ 40° B: 5/8″ 13/32″ 40° 3VX: 3/8″ 21/64″ 40°
What are V belts used for?
– conveyors – compressors – machine tools – cooling Towers – Small gear boxes
What is a V belt?
– They transmit higher torque with lesser width and tension compared to other type of belts. – They can be used in areas with very less arc of contact of the belt. – They can be operated in speeds ranging between 5 to 30 m/sec.
