What is a shim?
Imagine a thin flat washer. Now imagine that a washing machine can solve many mechanical problems. That’s the nature of shims. These unsung heroes come in all shapes, sizes, and materials, but their core function remains the same: carefully tuned spacing and alignment between components.
Understanding Shims: Types and Functions
In this section, we’ll delve into the complex world of shims and their various types—solid shims, slotted shims, and more. From their precise functionality to practical applications across industries, we reveal the versatility and importance of each type. Whether you are a mechanical engineer, a DIY enthusiast, or someone interested in shims, this section provides insights to enhance your understanding.
Manufacturing Process of Metal Shims
1-Stamped metal shim
Stamping is a common method for producing metal shims. The process involves using a custom mold to apply controlled force to cut and shape the required shims from the sheet metal, providing speed and efficiency during high-volume production and delivering reliable and accurate components.
Stamping does have limitations, however, including reduced material versatility, the potential for burr formation during processing, and the potential for uneconomical die set-up costs for hard molds.
2-Laser Cut Metal Spacers
Laser cutting is known for its precision and versatility, making it another popular processing method. There are challenges when working with highly reflective metals and complex designs. Additionally, the high temperatures generated during laser cutting can create thermal stresses that can adversely affect the performance of metal shim manufacturing components.
3-Water jet cutting metal shim
Waterjet cutting uses a high-pressure stream of water mixed with abrasive particles to precisely cut a variety of materials, providing versatility and speed for simpler designs and prototypes. However, it may cause problems with component quality and aesthetics due to burr formation and rough texture.
Industrial Applications of Metal Shims
Uses in the oil and gas industry
Various oil and gas industry applications make use of precise metal shims. Metal shims are commonly employed in many components such as pumps, compressors, turbines, electric motors, gearboxes, and torque converters. They offer savings in terms of cost and time at all stages during the life cycle of equipment right from assembling and installing to refurbishing and retrofitting. We shall now see some uses of these shims in the petroleum industry:
- Space Compensator: Increased tolerances can cause axial movement in shaft components such as motors, generators, pumps, gearboxes, and torque converters, significantly shortening the service life of the components. These tolerances can be absorbed using precision metal shims.
- Thrust Washers: Metal washers can be used as thrust washers when the applied stresses are not too great and are an economical alternative to roller thrust bearings.
- Spacers for mating surfaces: Precision metal spacers can be installed in the space between the mating surfaces of two parts or components. In addition to mating components, they have many advantages: By using precision shims to compensate for the resulting space, mating surfaces on cast or machined parts manufacturing to less precise tolerances, thus reducing production costs. Additionally, when made from a slightly softer material than the mating component, the metal shim manufacturing can act as a sacrificial plate, absorbing the wear typically caused by natural friction, wear and tear on the mating surfaces. The technology also significantly reduces turnaround time and costs during equipment replacement or retrofit operations by eliminating the need to resurface mating components.
- Leveling shims: To ensure precise alignment of the two components, leveling metal shims (also called pump shims or foot shims) are inserted into the bottom of the mating component. This is critical to avoid any angular misalignment between rotating parts, which could lead to premature failure.
Domestic application of metal shims
- Even with the most precise measurements and attention, it is doubtful that a door or window will be completely square without adjustments after installation. Spacers are used to make final adjustments rather than painstakingly cutting new frames or trying to nail in extremely precise openings. After a door or window is installed, shims should be used to fill the gap between the window or door frame and the frame opening.
- The first step in gradually leveling and vertically connecting the elements is to wedge shims between the frame and adjacent studs. This is done by using a level to check whether the window or door moves in a vertical or horizontal direction as required. Next, use a hammer or mallet to gently tap the spacer into place. It is crucial to follow this procedure. If the first shim is insufficient to make the necessary adjustment, a second shim must be placed next to the first shim, but facing in the opposite direction. Avoid driving the shim too deep as it will be difficult to remove once it is in place. Once the door or window is level and plumb, it can be secured with nails or screws through the casing, spacers, and frame. The final step is to use a utility knife to score the extra length of spacer and snap it off once the window or door is securely in place and nailed.
- If your wheels are misaligned due to rust, dirt, or paint adhering to the wrong location, you can use metal shims to realign the wheels.
- Cycling shoes come with spacers that contain a mechanism to accommodate the cleat on the bicycle pedal so that the height of the cleat can be changed as needed. These cycling shoes include a set of lightweight spacers and a pair of heavy-duty spacers.
- Metal spacers are used in home crafting areas to protect surfaces when using die cutting or embossing tools. In this case, the base component is protected from damage when cutting and embossing pressure is applied.
Frequently Asked Questions
