Compound Bow Pulley System
Compound bow pulley system. The pulleycam system grants the user a mechanical advantage and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow. To paint a clearer picture a compound bow with a draw weight of 60 lbs. The goal of these components is to decrease the amount of weight the archer holds at full draw thus making aiming much easier.
By use of a pulley system compound bows can utilize rigid limbs that reduce energy waste and result in greater arrow velocity. The riser can be seen as the backbone of the bow. Craig Yehle director of research and development at Bowtech Archery received a patent 1 for the design on December 11 2007.
The details that differentiate a recurve crossbow from a pulley one. Bowtech started equipping its bows with the new cam design in the 2005 model year. Most models have limbs made of composite materials.
Compound bow has a very complex mechanism that includes a pulley system and requires some use beforehand to learn how to handle the weapon properly. Like all bows this type of bow has limbs. Generally compound bows generate more power than recurve bows thanks to their pulley system and mechanical cam.
A compound bow is a modern bow that uses a levering system usually of cables and pulleys to bend the limbs1 The pulleycam system grants the wielder a mechanical advantage and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow. The binary cam is a design for the pulley system of a compound bow. In modern archery a compound bow is a bow that uses a levering system usually of cables and pulleys to bend the limbs.
The pulley mechanism forms the main difference between a compound crossbow and a recurve crossbow. Hopefully now the next time somebody asks you How does a compound bow work youll be able to provide them with a reasonable answer. The higher-rigidity higher-technology construction also.
What is a compound bow. The moment transfer pulley system includes a pulley assembly 38 having a primary axle hole 76 and a primary axle 44 upon which the pulley assembly rotates.
A compound bow is the technological pinnacle of one of the first mechanically assisted projectile weapons ever invented.
Eventually as a result less force has to be exerted by the archer and more powerful and accurate targets can be achieved. The moment transfer pulley system includes a pulley assembly 38 having a primary axle hole 76 and a primary axle 44 upon which the pulley assembly rotates. 1 The pulleycam system grants the wielder a mechanical advantage and so the limbs of a compound bow are much stiffer than those of a recurve bow or longbow. The amount of weight reduced is called a let off and this is one of the features of a compound bow buyers carefully look at. To paint a clearer picture a compound bow with a draw weight of 60 lbs. Like all bows this type of bow has limbs. In addition compound bows help one shoot accurately thanks to the draw stops unavailable on recurve bows. Since a compound bow operates on a pulley system it is essential that the limbs are durable and able to withstand an incredible amount of pressure. These lengthier parts of the bow are responsible for storing the energy that is built up when the archer draws the bow.
A compound bow is a modern bow that uses a levering system usually of cables and pulleys to bend the limbs. In addition compound bows help one shoot accurately thanks to the draw stops unavailable on recurve bows. There are a few parts that are important to note. HRCHCG 38 inch Aluminum Compound Bow Cable Slide Archery Bow String Splitter Roller Glide Replacement Bowstring Separator Arrow Pulley 41 out of 5 stars 35 1299 12. Since a compound bow operates on a pulley system it is essential that the limbs are durable and able to withstand an incredible amount of pressure. This rigidity makes the compound bow more energy-efficient than other bows as less energy is dissipated in limb movement. Generally compound bows generate more power than recurve bows thanks to their pulley system and mechanical cam.
