The Features of Retaining Wedge & Its Uses

Image for post

A wedge is a triangular object that is placed between two objects to hold them in place or to move them relative to one another. Retaining Wedges can be used to separate or retain items together. A wedge can be formed by one or more slanted planes. To make a double wedge, two inclined surfaces are linked with their sloping sides facing outward. Retaining Wedges are used to raise or lower the height of heavy objects, such as this massive steel pipe.

Significant and normal friction forces are regularly applied to wedges. A set of Retaining wedges with sufficient friction forces to prevent it from being pushed out. In this post, we'll go through the retaining wedge in great detail.

Features of Retaining Wedge

· Retaining wedges are useful for industrial machinery that requires precise levelling, vibration absorption, and sturdy support. A centrally positioned movable bolt slides the middle wedge between the top and bottom wedges on this three-piece wedge mount.

· In machines such as injection mold machines, lathes with long beds, CNC machine centers, and other machines used in engineering, plastics, machine tool industry, textiles, steel industry, and other industries, these three machined wedges are held together by a horizontal adjusting bolt and the retaining pin.

· The retaining pin holds the mount in place, while the wedges on the key allow for precise levelling. As a result of the anti-skid plate on the top wedge, the machines are free standing. Machine stability, rigidity, and solidity are all enhanced by a greater supporting area. Vibration control can be performed by placing appropriate insulating plates, depending on the type and frequency of vibration caused by the equipment.

Maintaining Coil Shape with Winding Wedge Retention

A winding retaining wedge retention system for maintaining coil form includes a rotor with a plurality of rotor poles, a coil wound on one of the rotor poles, a V-shaped support wedge positioned between adjacent rotor poles and adapted to support the coil, and a second wedge positioned between and adjacent to the coil and the rotor pole on which the coil is wound. The second wedge retains the coil in a steady form and keeps the coil in a constant position relative to the support wedge in the presence of centrifugal stresses.

In addition to the rotor itself and coils wound on each of the rotor poles, a winding wedge retention system for the entire rotor includes plural V-shaped support wedges positioned between each adjacent pair of rotor poles and plural dove-tail shaped wedges positioned between and adjacent to each of the coils and rotor poles. The dove-tail wedges are customized to move toward the surrounding supports in the presence of centrifugal loads, preserving the coils' shape and position relative to the location of the support wedges.

One of several approaches is used to keep the middle wedge in place. One method involves maintaining the wedge itself under the pole tips, which can be accomplished by combining numerous wedges. The cooling wedges are held in place by rotor end bands in a second way, which is more typically used in designs that have conduction cooling through their so-called cooling wedges.


The mechanical advantage of a wedge with a longer and narrower tip is greater. For millions of years, people have used retaining wedges. To hunt, cut and trim trees, and chisel stones, early humans utilized retaining wedges composed of hard pebbles and stones. Airplanes and modern automobiles both require retaining wedges. A center wedge is used in most wound generator rotors to keep the copper coil (winding) in the rotor slot.
