How do you know what size V-belt to get?
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 lengths do V belts come in?
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 V-belts are specified?
The length of a V-belt can be specified in several ways, including outside length, effective length, and pitch (or datum) length. Alternatively, the pitch length is measured at the pitch diameter of the sheaves. Both effective length and pitch length are measured with the belt tensioned by a specified amount.
What are the dimensions of a belt?
The width of your belt is determined by the type of belt that you’re going to wear. Casual belts are typically 1.25 to 1.5 inches (3.18 to 3.8 cm) wide. Dress belt are typically 1.25 inches (3.18 cm) wide, and should never be 1.5 inches or more, as that is too casual.
How do you measure the length of a belt?
Although commonly thought, the size of a belt is not determined by measuring the whole length of the belt but is taken from the length between the bottom of the buckle and the middle buckle hole. To determine your belt size, take your hip or waist measurement, depending on where you intend to wear the belt; the measurement is your belt size.
What is a B Section V belt?
B – The B stands for a “B” section v-belt. This is considered a “Classic” v-belt style that has a top width of 21/32 (0.656) inches, but is commonly referred to as a 5/8 (0.625) inch belt. The thickness of the belt is 13/32 (0.406) inches. 120 – 120 inches is the inside circumference of the belt. For B-section v-belts,…
What is the angle of V belt?
All v-belts have a 40° angle between the faces, except the V series (aka “Harvester” or “Wedge” belts), which have a 30° angle between the faces. You will notice that the inside edge of the belt is wider than the base of the V in a v-belt pulley – the belt touches the pulley only on the sides.
