Mech Projects: Welding:
http://mechprojects.blogspot.com/2008/01/welding.html
Wednesday, January 9, 2008. Once the sheets are bent they are welded together to form cylindrical shape for this purpose carbon arc welding is used. It is the process in which a pure graphite rod of 4. Diameter and 300 to 400mm. Length. Non-consumable electrode is used to create an arc between it and work piece by holding it in electrode holder with an electrode extension of 15 to 125mm. Length, the temperature of the weld pool can be easily controlled by varying the arc length. Light The space between t...

Mech Projects: Types of insulation:
http://mechprojects.blogspot.com/2008/01/types-of-insulation.html
Tuesday, January 8, 2008. Flake insulation (fine particles). Granular insulation (Magnesia or cork). Cellular insulation (rubber or plastic). Heat transfer through insulation:. The heat flow by conduction is reduced due to the long path followed through the insulating material and due to very low conductivities of air gaps and material itself. The heat flow by radiation is also considerably less because most of the insulating materials are opaque to radiation. The moisture content in the insulating mater...

Gear Manufacturing (By Cutting): Gear Materials
http://gearcutting.blogspot.com/2008/02/gear-materials.html
Gear Manufacturing (By Cutting). Wednesday, February 27, 2008. The material used for the manufacture of gears depends upon the strength and service conditions like wear, noise etc. The gears may be manufactured from metallic or non-metallic materials. The metallic gears with cut teeth are commercially obtainable in cast iron, steel and bronze. The non-metallic materials like wood, raw hide, compressed paper and synthetic resins like nylon are used for gears, especially for reducing noise. Feed motions of...

Gear Manufacturing (By Cutting): Feed motions of hob cutter
http://gearcutting.blogspot.com/2008/02/feed-motions-of-hob-cutter.html
Gear Manufacturing (By Cutting). Wednesday, February 27, 2008. Feed motions of hob cutter. Axial feed is the most commonly used feed, unless there is restriction for axial motion. The hob is fed to the full depth form and then fed in axial direction to generate the full width of the gear. Labels: Feed motions of hob cutter. Gear cutting tool design and production requires much specialized knowledge, which has been acquired and refined over generations. April 13, 2011 at 2:35 AM. May 4, 2011 at 9:13 PM.

Gear Manufacturing (By Cutting): Introduction to Gears
http://gearcutting.blogspot.com/2008/02/introduction-to-gears.html
Gear Manufacturing (By Cutting). Wednesday, February 27, 2008. Spur gears are the most commonly used gears, are used to transmit motion between parallel shafts. These impose load on bearings. Its teeth are straight and parallel to the axis. These can be either internal type or external type. An external spur gear of infinite radius, called as rack. Rack has straight-sided tooth (for involute tooth profile gears). Labels: Introduction to Gears. Design and production requires much specialized knowledge.

Gear Manufacturing (By Cutting): Law of Gearing
http://gearcutting.blogspot.com/2008/02/law-of-gearing.html
Gear Manufacturing (By Cutting). Wednesday, February 27, 2008. The law of gearing states the conditions which must be fulfilled by the gear tooth profiles to maintain a constant angular velocity ratio between two gears. It states that the common normal at the point of contact of the two teeth should always pass through a common pitch point. Labels: Law of Gearing. Subscribe to: Post Comments (Atom).
