V Belts Basic Technical Parameter:
V belts (also named rubber V belts, Vee belts, or poly vee belt, etc) solved the slippage and alignment problem in power transmission. It is one of the basic belts for power transmission. They provide the best combination of traction, speed of movement, the load of the bearings, and long service life. Classic v belt products models included: Z,M,O,A,B,C,D,etc.
Industrial v belts are generally endless, and their general cross-section shape is roughly trapezoidal (so-called the name of “V”). The “V” shape of the belt tracks in a mating groove in the gearbox pulley, with this result that the belt cannot slip off. The rubber v belt also tends to wedge into the groove as the load increases—the greater the load, the greater the wedging action—improving torque transmission and making the Vee belt an effective solution, needing less width and tension than flat belts. V-belts trump flat belts with their small center distances and high reduction ratios. The preferred center distance is larger than the largest pulley diameter, but less than three times the sum of both gearbox pulleys. suitable speed range is 1,000–7,000 ft/min (300–2,130 m/min). poly vee belt needs larger gearbox pulleys for their thicker cross-section than flat belts.
Classic v belt products models as below:
Section Profile | Top Width | Height | Angle° | Material | Length standard | Remark |
Z | 10mm | 8.5mm | 40° | NR | Li / Lw / Lp | 38° angle if inches |
A | 13mm | 9mm | 40° | NR | Li / Lw / Lp | 12.7mm = 0.5 inch width, 38° angle if inches |
B | 17mm | 11mm | 40° | NR | Li / Lw / Lp | 16.5mm = 21/32 inch width, 38° angle if inches |
C | 22mm | 14mm | 40° | NR | Li / Lw / Lp | 22.2mm = 7/8 inch width, 38° angle if inches |
D | 32mm | 19mm | 40° | NR | Li / Lw / Lp | 31.75mm = 1.25 inch width, 38° angle if inches |
E | 38mm | 25mm | 40° | NR | Li / Lw / Lp | 38.1mm = 1.5 inch width, 38° angle if inches |
For high-power requirements, exceed than two V belts can be joined side-by-side in an arrangement called Banded v belt (products model: SPA, SPB, SPC, etc), or multi v groove belts, the banded v belt running on matching multi-groove sheaves. This is known as a multiple V groove belt (or sometimes called banded v belt ).
the banded v belts products model as below:
Application :
V belt assembly with gearbox pulley, with industrial gearbox, the combination of power transmission. v belts wide use on small electric tools,food machinery,fishing boats,fan,energy industry,snowplow,agricultural machinery,construction machinery,mining Machine,etc.
