Since 1916, the automotive V Ribbed Belt trade magazine reported that leather for the belt material, and mentioned V angle has not yet standardized. Seamless Rubber V-belt was developed by Gates Rubber Company's John Gates in 1917.
V ribbed belt solves the problem of slip and alignment. Now is the basic band of power transmission. They provide the best combination of traction, movement speed, bearing load and long service life. They are usually endless, and their total cross-sectional shape is trapezoidal (hence called "V"). The "V" shape of the tape is in the mating groove in the pulley (or pulley), with the result that the belt does not slip off. When the load increases, the belt also tends to wedge into the groove, the greater the load, the greater the wedge effect, the greater the torque transmission, and make the V-belt as an effective solution, need to be smaller than the flat width and tension. V-belt with a flat belt center distance and high reduction ratio. The preferred center distance is greater than the maximum pulley diameter, but less than three times the sum of the two pulleys. The optimum speed range is 1000-7000 ft / min. V ribbed belts require larger pulleys because they are thicker than flat belts.
For high power requirements, two or more v belts can be connected side by side in a multi-V arrangement, running on a matching multi-slot pulley. This is called a multi-V drive. The V-belt may be a uniform rubber or polymer, or may have fiber strength and strength in the rubber or polymer. The fibers may be textile materials such as cotton or polyester, or the strongest steel or aramid. When the ring belt does not meet the needs, you can use the connected v ribbed belt.
However, they are weak and can only be used at speeds of up to 4000 feet per minute. The connecting v tape is a plurality of rubber fabric links that are secured together by metal fasteners. You can adjust the length by removing and removing the link as needed.
