Spur Gears
Spur gears are the most common and also the oldest type of gear available. They are used in many different machines for a wide variety of functions. Although they are very simple in design, several different, discrete types of spur gears exist. Anyone who is interested in mechanical engineering or who is about to undertake a project that involves the use of gears of any type ought to familiarize themselves with spur gears and the ways in which they are used.
Spur gears are extremely important mechanical components and come in many varieties.
Spur Gears in General
In general, spur gears are round metal disks with teeth cut around the circumference. In order for the gear to qualify as a spur gear, the teeth must be cut so that they run perpendicular to the gear's face. Spur gears are the simplest design of gear produced. They are usually used for the transmission of rotary force. For instance, if two shafts are parallel to one another, and one is spinning, a spur gear can help to transfer that force onto the other shaft. Spur gears usually have an operating efficiency of 98% to 99%.
Spur Gear Blanks
Spur gear blanks are spur gears with no teeth cut into them. These types of spur gears can be useful if you do not yet know the precise number of teeth you will require for your spur gear's application.
Spur Gear Materials Spur gears can be built from a wide variety of different materials. Different materials are often used for different types of applications. For instance, cast iron spur gears are strong and are used in many commercial applications. Aluminum alloy spur gears, conversely, are lighter but can also be built into more precise shapes, so they are used for low-impact applications requiring high precision, such as measuring instruments. Other materials from which spur gears are built include cast steels, carbon steels, stainless steels, brass, magnesium and titanium alloys, and sometimes even nylon.
Anti-Backlash Spur Gears
Antibacklash spur gears, as their name suggests, have little to no backlash, and so are used in high-precision applications. Often, these spur gears are built with springs for proper tensoring. They are usually built from brass, aluminum or stainless steel. In order for antibacklash spur gears to work together, they must have the same diametral pitch and pressure angle.
Cluster Spur Gears
Cluster spur gears come "clustered" together, usually on the same shaft, and have varying diameters.
Clamp Hub Spur Gears
Clamp hub spur gears are named for the manner in which they connect to their shaft, that is, with a clamp at the spur gear's center.
Pinion Shafts Pinion shafts are basically stretched-out spur gears, cylinders with teeth running for their entire length. Ratchets and Pawls Ratchets and pawls are two spur gears that work together. Ratchets are gear wheels with teeth, while pawls are spring-loaded and pivot. Pawls are usually slanted. Together, these gears allow for unidirectional movement.
Hubless Spur Gears
Hubless spur gears have no hub and instead connect to their shafts through friction or with adhesive.
Pin Hub Spur Gears
Pin hub spur gears connect to their shaft through the use of a removable pin as opposed to a clamp.

Mining Metal
Mining Metal Detectors
Mining metal detectors are suitable solutions for mining applications. They can prevent damage to crushing machines, conveyor belts and other machinery in advance by detecting iron pieces contaminated in crushed stone and ores.
Digital metal detectors used for landmine detectors are also found. Usually, this process is done for humanitarian reasons or to enable military action. Mining metal detectors suitable for humanitarian application and military demining features detection head, telescopic handle and high impact polypropylene case.
Some mining metal detectors combine a control unit and search coil into a single unit, resulting in a compact design. The installation procedures are simple and easy. For mechanical installation, four point attachments to the conveyor frame are essential. The electrical work consists of connecting only three cables, including the power cable.
Mining metal detectors are also able to remove non ferrous metal components that cannot be detected using magnetic separators. Some models work in an efficient manner for high-manganese steel. Most of the metal detectors for mining projects use steel plated and water resistant construction. Some come with M type search coil. This mono-frame coil reduces the need for coiling work at the installation place. Vibration resistance is another added advantage.
