What is a split pin?
A split pin is a simple fastening element generally made of a soft, malleable metal used to lock low torque rotating on site. The split pin usually consists of a flat, round or half -round pin with an explicit loop at a closed end. After the part of the part, the pin passes through the hole in the shaft and one or both "legs" bent back to prevent free work, while the loop at the closed end stops in the fall through the hole. If the part must be removed, the bent pin legs are simply straightened and the split pin is removed.
Split pins are among the cheapest and most used locking fasteners for low speed and low voltage. You can find them in countless applications from brake disc locks on heavy vehicles to paper puppets and plush toys. These fasteners are also known as Pins Cotter, available in a number of sizes and patterns including straight pins, spring pins and hammer pegs. There are also differentNo cross -sectional profiles, such as round, flat or half wheel. The split pin is also available with various end profiles, including the ends of the bevels, the end ends and the enlarged Pols on the Prontg, which are suitable for specific use.
The part of the beauty of the use of divided pins as fasteners is their absolute simplicity. Once the part to be locked, the adjacent locking hole is promoted on site until the end loop or eye vaccination stops another. One or both legs then bend back to prevent free processing of the pin, thus effectively preventing part of its housing or coming out of the shaft. However, there are several designs of divided pins, such as a spring pin, which are a bit more sophisticated. These pins have a spring steel construction and a "abdominal" profile in one of the legs that locks around the outer surfaceround shafts.
One of the known uses of Split PIN is Locking mechanism for castle nuts commonly used in automotive centers. These lightweight nuts lock the charges in place and develop a suitable amount of torque on the wheels. They contain a number of raised cards along their upper edges reminiscent of the castle battle. The upper axle has a drilled hole through it and once the matrix is tightened to the right torque, the split pin is inserted through the hole between the cards on the nut. The ends are then bent back to lock the pin and prevent the castelic matrix from being released.
Materials used in the production of divided pins tend to be soft, spherical metals such as aluminum, bronze, brass and soft steel. This allows easy bending of the legs when locking the pin in place. Unfortunately, this also means that their legs will survive only once or twice before they fall apart. For this reason, divided pins should only be used once and then discarded; This is quite acceptedElna when considering low cost of these verteskes small fastening elements.
