A grease gun (grips gun) is a hand-held device used for lubricating. The main function of the grease gun is usually to apply grease to an oil fitting or ‘nipple’ through an open-enable aperture. The gun is used to keep a piece of equipment free of dirt, grease, water, etc. Common examples are exhaust systems on engine blocks, radiators, pumps, valves, pumps, gearboxes, brake drums and clutches. The most popular application is on threaded components such as bolts.
The grease gun was invented in the late 19th century by Rev. Thomas Edison (who also developed the light bulb). He used the device in order to pump grease into a small tube. This small tube is called a pneumatic tire. Many innovations followed and the modern day grease gun makes cleaning a lot easier.
One typical use of a lubricating grease gun includes changing, installing and maintaining bearings. To change bearings involves removing a set of sprockets, removing a bearing and inserting a new sprocket in its place. The new sprocket is then aligned with the correct or specified point on the bearing shaft. To install bearings is also similarly simple; it involves removing the existing or previous set of bearings and installing a new one.
Another type of grease gun consists of a trigger mechanism. A trigger mechanism may be used to activate the mechanism when a certain amount of pressure is applied to the trigger handle. Some trigger mechanism uses gravity to activate the mechanism; others involve pneumatic air pressure or hydraulic pressure. Depending on the particular application, either gravity or air pressure may be used. The general idea behind both trigger mechanism types is to allow for application even without the assistance of a manual pump or mechanic.
Grease guns are primarily used to clean grease buildup in equipment such as ovens and freezers. Because ovens and freezers are so well-suited to high-heat processes, grease buildup is very common. In this situation, the grease gun can be a convenient tool to remove the build-up. One disadvantage to using grease guns to clean grease buildup in these types of environments is cross-contamination. Cross-contamination can occur if an operator or other people in the area are not trained or aware of how to properly use grease guns.
Another type of equipment that can suffer from cross-contamination is injection equipment. Induction equipment usually contains a lubricant to help reduce friction when metal parts are being melted or molded. Unfortunately, even a properly-molded or designed lubricant can still cause cross-contamination. If you have injection equipment in your workplace, you will need to install anti-cross-contamination grease fittings on all appropriate surfaces to avoid this problem.
The grease gun can also be helpful when using grease fittings in situations where mechanical lubricants or hand-powered grease guns are not available, and when cross contamination is an issue. The key to using a grease gun correctly is to carefully apply the grease in a fine and even flow. After applying the grease, you will want to wait several seconds before switching the nozzle so that the gun can cool off before reloading. Also, use the right type of nozzle with your gun for best results.
Hand-powered gun might be used when the environment requires a higher degree of lubricity than that achieved with a grease gun. Hand-powered lubricants are typically used in applications where there is little or no opportunity to manually control lubrication, and where the grease fittings do not need to withstand very high levels of friction. Using hand-powered grease guns is especially useful in applications that require a high degree of precision machining or other operations that depend on the smoothness and low friction. Because of their high tolerances, they have been used to repair many precision components.
