Abstract
Abstract An assembly of housings is secured is secured together by a plurality of bolt members. The assembly is subject to a source of vibration, such as an internal combustion engine. To ensure the natural frequency of the bolt is outside the operating range of the engine, tolerance support rings are installed to reduce the effective length of the bolts and thereby increase the natural frequency.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
In combination: a first housing; a second housing; a bolt passage in one of said housings having a predetermined diameter; bolt means for securing said first and second housings together at an interface and said bolt means including a head end, a threaded end and a cylindrical portion having a single continuous predetermined outer diameter less than the bolt passage predetermined diameter between said ends and being partially disposed in said bolt passage; and tolerance ring means disposed between the bolt passage predetermined diameter and the cylindrical portion and secured at a location on the bolt passage at a predetermined distance from the interface for supporting the bolt and affecting the natural frequency thereof.
Claim 2
Dependent Claim
114 words
In combination: a first housing; a second housing; a bolt passage in one of said housings having a predetermined diameter; bolt means for securing said first and second housings together at an interface and said bolt means including a head end, a threaded end and a cylindrical portion having a single continuous predetermined outer diameter less than the bolt passage predetermined diameter between said ends and being partially disposed in said bolt passage; and tolerance ring means disposed between the bolt passage predetermined diameter and the cylindrical portion and secured at a location on the bolt passage at a predetermined distance from the interface for supporting the bolt and affecting the natural frequency thereof.
Claim 3
Dependent Claim
126 words
In combination: a plurality of housing means; a vibrating source imposing a range of frequencies on said housing means; bolt passages in said housing means having predetermined diameters; bolt means for securing said housing means together at an interface and said bolt means including a cylindrical portion having a single continuous predetermined outer diameter less than the bolt passages predetermined diameters and being partially disposed in said bolt passages; and tolerance ring means disposed between at least one of the bolt passage's predetermined diameters and the cylindrical portion and secured at a location on the bolt at a predetermined distance from the interface for supporting the bolt and affecting the natural frequency thereof to be greater than the range of frequencies imposed on the housing means.
Claim 4
Dependent Claim
126 words
In combination: a plurality of housing means; a vibrating source imposing a range of frequencies on said housing means; bolt passages in said housing means having predetermined diameters; bolt means for securing said housing means together at an interface and said bolt means including a cylindrical portion having a single continuous predetermined outer diameter less than the bolt passages predetermined diameters and being partially disposed in said bolt passages; and tolerance ring means disposed between at least one of the bolt passage's predetermined diameters and the cylindrical portion and secured at a location on the bolt at a predetermined distance from the interface for supporting the bolt and affecting the natural frequency thereof to be greater than the range of frequencies imposed on the housing means.
