INERTIA RINGS
A harmonic damper for use in vehicular accessory drive systems. The harmonic damper includes a one-piece inertia ring manufactured from a sheet metal blank using a cold forming process to define a series of interconnected folded ring sections
The introduction of inertia terms into a theoretical model of thin ring expansion shows that classical plastic instability concepts, defined in terms of the local strain in the necking region, no longer apply. By introducing the role of void growth in triggering local necking, through a recently proposed constitutive equation for porous plastic materials, it is possible to overcome this difficulty. This theory was applied to a thin ring configuration, and the results were found to compare favorably with experimental values obtained from statically and dynamically loaded rings.
TRANSMISSION SHAFTS
A transmission shaft (also known as shaft) is a rotating machine element with circular cross section. Shaft is used to transfer rotary motion from one point to the other point.
Shaft is generally mounted with gears, pulleys and sprockets. With the help of these mountings power is transferred to the other shaft or to the point where it is actually used.
One the basis of application shafts are given different names. However, the purpose remains same i.e. transfer of torque, motion and power.
HUB/ PULLY/ MASS RINGS
Ring Rolling Forging, also known as roll forming, is a forging technique that involves shaping a metal object with opposing rollers. Although roll forging uses rolls to achieve material deformation, it is a discrete process, not a continuous one, analogous to metal forging rather than metal rolling.
Ring forging is frequently done in a heated environment. The roll’s grooves are carefully designed to forge the part to the desired dimensions.
The forging geometry of the rings used to forge metal items is only visible on a small fraction of the diameter of the ring. Only a portion of a full ring revolution is required to forge the workpiece.
Flex plate
Situated between the engine of a motor vehicle, and the gearbox and transmission mechanism, is a clever and essential device that has been fitted to engines of all shapes and sizes since the early days of steam locomotion up to high performance vehicles of the present day. That device is known as a “flywheel” and its somewhat more recent counterpart, which is fitted to engines within vehicles with an automatic transmission, is known as a “flex plate.”
Their roles in the task of driving a motor vehicle forwards, (or backwards for that matter), are virtually identical but it is the specific function of the flexi plate that we are discussing in this blog.
However, a flex plate, actually consist of two parts. The flex-plate and the ring gear, fitted to the outside of it.
