The pitch circle is an imaginary circle that passes through the points where two interlocking gears touch. It’s important to know the pitch circle diameter when calculating measurements related to gear mechanics. The teeth of the gears must rotate effectively, and the pitch circle can be subdivided into circular pitch, addendum, and dedendum. The pitch […]
Apron feeders are heavy-duty machines that transport materials through industrial processes. They are made of steel and resemble short belt conveyors. Apron feeders are used in mining, factories, and batching plants to regulate the volume and rate of materials added to a process. The materials are held in a hopper and deposited onto the metal […]
Magnet wire is coated with a protective enamel that can be soldered without stripping. The coating is made of polyurethane, polyamide, or polyester resins and is heat and voltage resistant. The wire’s color has no significance, and its rating is based on temperature and expected life. Rectangular wire is used in motors for efficient use […]
A grease pan provides lubrication to moving parts in engines and machines. It needs to be maintained and refilled when the lubricant depletes. Problems can arise from emptying, losing its seal, damage, wear and tear, and pressurization. Replacement cups are available, and maintenance is crucial to avoid costly repairs. A grease pan is a fitting […]
Resin coating, also known as powder coating, is made from synthetic materials and comes in three categories: thermosetting, thermoplastic, and radiation-cured powders.
