The difference between compound bow and recurve bow - structural composition

The bow used in recurve archery in modern sports is composed of the main parts such as the bow handle, bow limb, bow string, arrow rest, arrow side pad, sight and counterweight shock absorber. The compound bow is composed of the bow handle, bow arm, eccentric wheel, wheel axle, bow string, rear view window, tension adjustment bolt, cable, cable limit rod, string slide, arrow rest, sight, counterweight shock absorber and release device. Both recurve bows and compound bows are sports equipment that shoot arrows to the target through the elastic force of the bow limbs through effective and consistent artificial bow opening.
For bows with the same tension standard, the longer the bow of the recurve bow is pulled, the greater the tension is, and the farther the arrow can be shot. The compound bow uses eccentric wheels and fixed pulleys of different shapes installed at the top of the upper and lower bow pieces (most of the compound bows of the shooting type generally use symmetrical eccentric wheels), fix the positioning length cable and bowstring on the pulley positioning pin and install the bowstring of appropriate length through the pulley groove, so as to use the lever principle of the eccentric wheel to pull the bow with heavier tension.
The tension of the bow after being pulled will eventually be reduced by 65-75% according to the different shapes of the eccentric wheel. In other words, the force of the compound bow should be strong, and the symmetrical force of the bow after being pulled is greatly reduced. It is worth mentioning that the longest draw distance of the compound bow is not changed by the mutual restraint of the pulley positioning pin and the cable and bowstring.

Therefore, for the same bow, after the bow is determined, the tension is consistent, and theoretically the distance of the arrow shot is also equal.
