How do you measure a pulley groove?

Place your pulley face down on a flat surface, then put your ruler or caliper on top, measure from outside edge to outside edge across the circle of the pulley. Check carefully to make sure you are measuring across the center.

What size is V groove?

V-groove router cutters have diameters ranging from 9.5mm to 76mm in metric sizes and from ½” to 1¼” in imperial sizes. For wider grooves, select a cutter with a larger cutting diameter; for narrower grooves, select a cutter with a smaller cutting diameter.

What is the groove of a pulley?

A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain.

How do you find the diameter of a pulley?

Step 4: To determine diameter of pulleys. Step 5: Standard pulley diameters: d = 280 mm and D = 450 mm (OR) d = 250 mm and D = 400 mm can be selected. For this problem, d = 280 mm and D = 450 mm is selected….Step 7:

C min = 0.55 (D + d) + T
C max = 2 (D + d) = 2 (450 + 280) 1460 mm

How do you pick a V belt pulley?

Following are some environmental and application design criteria that will influence belt selection:

  1. Ambient temperature.
  2. Oil resistance.
  3. Ozone resistance.
  4. Static conductivity.
  5. Power capacity.
  6. Pulsation or shock loading.
  7. Small sheave diameters.
  8. Backside idlers.

What does the groove weld size indicate?

The size of the weld is the effective throat on a groove weld. This includes the depth of groove and the additional penetration into the root.

What is au groove weld?

[′siŋ·gəl ′yü ¦grüv ‚weld] (metallurgy) A groove weld in which the joint edge of both members is prepared in the form of a J from one side, giving a final U form to the completed weld.

What is the difference between A and B belts?

V-belt cross sections can be identified by their top width and depth dimensions. For example, a v-belt with a top width of 21/32” and a depth of 7/16” is a “B” belt. You can also use our Browning Belt Rule that includes a gauge to help easily identify belt type.

What are the parts of a pulley?

The three different pulley parts are a wheel, an axle, and a rope. The advantage of using a pulley is that it both changes the direction and point of application of force, making it much easier to lift weights.

How many grooves are there in a solid vbelt pulley?

Balanced General Purpose solid vbelt pulleys without taper bush A section 1 to 5 grooves 2~26 inch OD ; B section 1 to 5 grooves 2~40″od ; C section 3~8 belts groove 3~50″ OD ; D section 3~12 belts groove 12~56″ OD ; E section 5~15 belts groove 16~72″ OD.

What are the basic requirements to choose a pulley?

Size i.e. pulley pitch dia, whether 75mm or 125mm & so on. 2. No. of grooves i.e. 2,3 & so on. 3. For V-belt section i.e. A or SPB & so on. 4. Type i.e. general purpose or quick-fit with taper lock bush. 5. Bore size i.e. pilot or some requisite size. 6. Key waying, if at all reqd. (length, width & depth). 7. Quantity in nos. 8.

How many flanges does a belt pulley have?

Most pulleys will have two flanges to keep the belt from slipping, but some operations work best without any: Pulleys with no flanges are typically used on flat belt applications. The rare product with only one flange is recommended for Genuine OEM Replacement only.

What is the offset of a pulley?

The offset is the distance from the centerline of the pulley to the outside edge of the bore. On a V-groove drive, for instance, the centerline or “middle” of a pulley would be the lowest point of the V, and you would measure from there to the edge of the hub.
