V-belt Pulley

【Name】 

Commonly referred to as Triangular Pulleys or V-Belt Pulleys 

【Description】

V-Belt Pulleys are common mechanical transmission components used to connect two or more wheels to transmit power. 

• Structure and Material: V-Belt Pulleys have groove shapes resembling the letter "V", hence the name. They are typically made of cast iron, steel, or other metals and can be surface-treated to prevent rust. (Our company provides services such as electroplating.)

• Selection and Ordering: When selecting V-Belt Pulleys, various factors need to be considered, including the size, shape, material, and shaft hole size of the pulleys.

• Usage: V-Belt Pulleys are primarily used in transmission systems such as automotive engines, industrial machinery, etc. They effectively transmit power with smooth operation and minimal noise.

• Calculation Basis: Designing V-Belt drive systems involves calculations such as belt length, power ratios, and contact arc correction coefficients.

• Installation Method: Straight-hole installation involves directly mounting V-Belt Pulleys onto the shaft. This installation method requires ensuring that the shaft hole and shaft diameter match precisely to securely fix the pulley on the shaft.

• Fixing Method: Straight-hole installation typically uses keyways or press-fit screws to secure the pulley. Keyways are grooves cut into the shaft and pulley's shaft holes, allowing insertion of a metal piece called a "key" to prevent the pulley from sliding on the shaft. (Our company provides keyway machining/grooving services.)

• Features: The main advantage of straight-hole installation is its simple structure, making installation and removal relatively easy. This installation method may require precise shaft hole dimensions

【Actuation】 

Elements constituting actuation include shaft holes, keyways, locating pins, and locking screws. 

【Production】 

• Standard products use inch units. 

• From casting to machining, and surface treatment, we provide a one-stop production solution. 

• Through equipment chaining, we pursue maximum mass production with short lead times.

• Through independent operation production, we pursue a wide variety of small-batch production with short lead times.

• The standard for outer diameter balance quality is based on the maximum value of 0.2% or 3g of the pulley's mass.

• Accuracy complies with various specification standards. 

【Applications】 

Commonly used in fans, machinery, transmission mechanisms, etc. 

【Applicable Belt Models】 

• Power Transmission Belts (Wrapped classical belt/Classical v-belt): M, A, B, C, D, E. *Models K, M, 3L, 4L, 5L also used for general power applications; differences in width should be noted. (Also known as Standard Triangular Belts)

• High horsepower belts (Wrapped narrow wedge belt): 1. European standards SPZ, SPA, SPB, SPC 2. American standards 3V/9N, 5V/15N, 8V/25N. (Also known as High Tension Belts)

• Light-duty belts: K, M, 3L, 4L, 5L.

• Multi-ribbed belts (Banded narrow wedge belt/Ribbed belt): H, J, L, M. Thinner type compared to other triangular belts. The thinness of multi-ribbed belts allows for maximum flexibility and suitability for smaller pulleys. (Also known as Multi-ribbed Belts) 

• Hexagonal belts (Double V-belt/Hexagonal belt): AA, BB, CC. (Also known as Hexagonal Belts) 

• Variable speed belts

• Cogged raw edge narrow wedge belts: 

  1. European standards XPZ, XPA, XPB, XPC

  2. American standards 3VX, 5VX, 8VX 

  3. Japanese standards MX, AX, BX, CX (Also known as Cogged raw edge narrow wedge belts)
