Problems solved by technology

However, where high frequencies are required for the TVD, this direct drive TVD suffers from three main limitations:
However, the addition of carbon black causes two additional problems:
[0011] (3) The lack of axially available packaging space for a TVD with a single spring / damper system causes problems because it limits the width of the elastomer and thus its torsional stiffness kt, based on the following equation:

Embodiment Construction

[0032] Reference is now made in detail to the description of the embodiments as shown in the accompanying drawings. While several embodiments are described in conjunction with these figures, there is no intent to limit the disclosure to the embodiment or embodiments disclosed herein. On the contrary, the intention is to cover all alternatives, modifications and equivalents.

[0033] now refer to figure 1 , shows an example of one embodiment of a FEAD system 18 comprising, for illustrative purposes only, a one-piece housing 15 having a front surface 30 and a rear surface 27 . The rear surface 27 of the one-piece housing 15 is preferably mounted to the engine. The FEAD system 18 may be used with any engine, including vehicular, marine, and stationary engines. The shape and configuration of the one-piece housing 15 depends on the vehicle engine to which it is to be installed. Thus, the integral housing 15 and more specifically the FEAD system 18 can vary with the location of ...

Abstract

A method of making stamper plates for an embossing drum for embossing tape media is provided. The method includes forming one or more first stamper plates using a master template, and forming a second stamper plate from one of the one or more first stamper plates such that the second stamper plate and the one first stamper plate have inverse land and groove patterns. Furthermore, the second stamper plate and the one first stamper plate or another of the one or more first stamper plates are useable on the drum to emboss tape media.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application No. 62 / 044,532, filed September 2, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to torsional vibration dampers, and more particularly to torsional vibration dampers having biaxially oriented elastomers, such as those used in direct drive crankshaft dampers and drive train dampers . Background technique [0004] A conventional torsional vibration damper (TVD) has a single mass spring system for damping vibrations provided by a strip or ring of elastomer that simultaneously holds the TVD's hub and ring relative to each other . More recently, with the advent of Belt Start Generator (BSG) systems, there has been a need for a TVD with an inertia ring integral to the hub so that the drive from the crankshaft to the belt is direct (not through elastomers). However, where high frequencies are required for ...
