What is Cotter?
and Cotter is a term used to describe the selection of devices designed to lock or secure pins, nuts, screws or complete mechanisms. Depending on the location, Cotter is also known as Split or Cotter PIN and can take the form of a simple metal pin or machined wedge. Cottters type of pins usually pass through the opening in the shaft or into the machined groove to prevent free processing of locking mechanisms. In the United States, this term concerns various types of pins, which include R-rounds, pegs for bridges and pegs in the spring. In the UK, this term describes a cylindrical strip machined in a wedge at one end and is commonly used to lock pedals and clicks on the bike.
Most of the fasteners subjected to vibration or repeated movement have an unpleasant tendency to work after a while. One way to prevent this is the use of one of the many types of kotter pins designed to prevent unintentional release of fasteners. This useful will seeDrive is available in a variety of design or ensure the same wide selection of fasteners. Most of them are simply spring -specific spring pins. Some, however, can be solid steel bars with one wedge face used for rotary mechanisms for friction.
The simplest example of these devices is a well -known type of split pin, which consists of a half -round pin bent double with a loop at a closed end. Two spikes or legs of the pin are inserted through the hole in the nut and the screw as soon as the nut is tightened. The ends of the legs then bend to prevent the pin from developing the way out of the hole. The PIN passing through the nut and the fibers to which it turns is prevented by the matrix in free operation. The same type of arrangement can be used on shafts where the pin prevents the shaft from the housing.
one particular type of locksThe shaft pipe is known as a circle and has a small belly or half the loop created in one leg. One leg of the pin passes through the opening in the shaft and the other passes through the outer surface until the belly or loop around the shaft around the shaft. These pins are usually made of spring steel and are repeatedly usable. Another common example of spring steel is the Cotter circle. They look similar to the key ring and fit into the groove machined into the shaft to stop the assembly at work from the shaft. In the UK, the term cotter is usually applied to a round steel shaft that has a wedge face facing one end used to lock the pedals and gears on their shafts.
