In general, a spacer is a solid material used to separate two parts in an assembly. Spacers can vary in size from microns to centimeters. They can be made of metal, plastic, glass, and other materials. Shapes include flat sheet, cylindrical and spherical. Two sizes of metal standoffs and one plastic standoff.
Linear Spacers (Section profiles, H-section profiles, or 3-dimensional shapes), Point Spacers (wheel spacers, various tower or chair-like shapes) Rebar spacers can be divided into three raw materials categories: Concrete spacers; Plastic spacers; Metal spacers; Each of these categories offer advantages which are specific to certain uses.
Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). Washers are usually metal or plastic. High-quality bolted joints require hardened steel washers to prevent the loss of pre-load due to brinelling after the torque is applied.
Interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings. On the London Underground signals and points are operated and controlled by an array of electrical, pneumatic and mechanical components. [ 1 ]
