Air ring gauge commonly known as ring gauge is a cylindrical ring of thermally stable material, often steel, whose inside diameter is finished to gauge tolerance and is used for checking the external diameter of a cylindrical object. In simple language, a ring gauge is a device used to measure air pressure.
Splines are ridges or teeth on a drive shaft that mesh with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.
A camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part. The camshaft was described in 1206 by Turkish engineer Al-Jazari. He employed it as part of his automata, water-raising machines and water clocks such as the castle clock. Among the first cars to utilize engines with single overhead camshafts were the Maud slay designed by Alexander Craig and introduced in 1902and the Marr Auto Car designed by Michigan native Walter Lorenzo Marr in 1903.
A method developed to monitor and control the processes involved in production to drastically reduce the problems and keep profitability and quality high by statisticians is known as Statistical Process Control or SPC. The SPC rules and methodology supporting this method must be properly applied to protect the credibility of the computations.
Snap gauges, also called gap gauges, are metrology tools that are used to gauge the diameter or thickness of a part or material. These tools are versatile and are designed to provide a quick go/no-go decision on cylinders, shafts, grooves, and other similar parts and features in machining operations. Functionally, snap gauges perform assessments on the outside diameters of parts, similar to other tools and measurement instruments such as ring gauges and thickness gauges. Snap gauges can be used for checking dimensions on both cylindrical and non-cylindrical parts whereas ring gauges are for cylindrical parts only. As a tool for inspection and quality control, the purpose of a snap gauge is to provide a rapid means of determining if the outside dimensions of the part are within its specified tolerances. It is a gauging tool principally, and as such is designed to perform an assessment of whether the part meets its dimensional specification without directly providing a measurement of the actual value of that dimension.
Spline shaft is an important part of a machine to transmit power or bear torque. Its section contour is like a gear. It suffers from great loads and alternating stress during the runtime. The tooth root of the spline shaft has a risk of fracture due to fatigue stress .Thus, it is essential to conduct a surface hardening process such as rolling after machining. In order to control the quality of product, a rolling performance evaluation becomes essential. The commonly used evaluation parameters of surface integrity involve the surface roughness, the surface residual stress and the micro-hardness.
A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine. They are mainly manufactured and classified on the basis of function and usability. The primary usage of the piston ring is to seal the chamber which can be a combustion chamber of a 2 stroke or a 4 stroke engine. Marine engines have three or more types of rings fitted on the circumference of the piston.
Some suppliers respond negatively to an importer telling them they’d like a third-party inspector to check the product at the factory. You might hear a supplier say something like “we don’t need them” or “we have our own quality control staff”.
It was a belief once; auto gauging systems are effective outcomes that are appropriate just for high-volume and long-run applications. Electronic auto gauging system for chamber liner is to check the internal and external measurement at three better places of all-out estimating length. In the days of yore, that may have been the situation, yet the cutting edge innovation of today has enabled producers to add greater adaptability to such systems. It measures neckline width and runs out of external Diameter regarding internal distance across. This settles on such systems an incredible decision for a few lower volume applications. After physically stacking the part all required parameters are estimated automatically, a show of the outcome on PC, physically emptying of the segment after estimation is finished. The fundamental advantage of auto gauging is consistency as it essentially evacuates each and every administrator related variable from the task.
A cylinder liner is a thin metal cylinder-shaped part which is inserted into the engine block to form the inner wall of the cylinder. In Japan, it is known as cylinder liner while in many countries it is popular as ‘cylinder sleeve’. It is one of the most important functional parts to make up the interior of an engine. During use, the cylinder liner is subject to wear from the rubbing action of the piston rings and piston skirt. This wear is minimized by the thin oil film which coats the cylinder walls and also by a layer of glaze which naturally forms as the engine is run-in. Cylinder liners are expensive, precisely manufactured products and are primarily purchased from specialty shops.
