Abstract
Apparatus and method for selectively determining the resonant frequency of a gas compressor including a compressor drive motor and a muffler in a generally spaced relationship, and an apparatus mechanically linking the compressor drive motor and the muffler. The apparatus as disclosed in one embodiment includes two conical frustums as wedge members, each having an axial bore accommodating a single non-resilient shaft for joining the conical frustums such that the shaft may be adjusted to force the wedge members closer together, biasing the muffler with respect to the compressor drive motor, and thereby adjusting the resonant frequency of the compressor structure to a determined resonant frequency.
Claims23
A gas compressor comprised of:
- means for compressing a gas;
- means for driving said compressing means, said drive means having an exterior portion thereof;
- a muffler attached to said compressing means, said muffler having an exterior portion thereof in a generally spaced relationship to said exterior portion of said drive means;
- and
- means for mechanically linking said exterior portion of said drive means and said exterior portion of said muffler, said means disposed between said drive means and said muffler, and said linking means being adjustable to selectively determine a resonant frequency of said gas compressor when said drive means is operative.
A gas compressor having a structural resonant frequency in operation, comprised of:
- a hermetically sealed shell;
- a mounting structure enclosed within said shell;
- means for compressing a gas mounted to said mounting structure, said gas compressing means having a drive motor operably connected thereto, said gas compressing means further including a muffler located in a generally spaced relationship with said motor;
- and
- means for adjustably mechanically linking an exterior portion of said motor and an exterior portion of said muffler such that said structural resonant frequency is adjusted to a selected, determined resonant frequency when said gas compressor is in operation.
A gas compressor having a structural resonant frequency in operation, comprised of:
- a hermetically sealed shell;
- a mounting structure enclosed within said shell;
- means for compressing a gas mounted to said mounting structure, said gas compressing means having a drive motor operably connected thereto, said gas compressing means further including a muffler located in a generally spaced relationship with said motor;
- and
- means for mechanically linking an exterior portion of said motor and an exterior portion of said muffler such that said stuctural resonant frequency is adjusted to a selected, determined resonant frequency when said gas compressor is in operation, said means for mechanically linking further including wedging means for physically biasing said muffler with respect to said motor and means for retaining securing said wedging means between the exterior portion of said motor and the exterior portion of said muffler.
A gas compressor having a structural resonant frequency in operation, comprised of:
- a mounting structure;
- means for compressing a gas mounted to said mounting structure, said gas compressing means including a motor secured thereto, said gas compression means further including a muffler located in a generally spaced relationship with said motor;
- and
- a one-piece wedge member for mechanically linking an exterior portion of said motor and an exterior portion of said muffler in a biasing, preload manner at a selected location such that said structural resonant frequency is adjusted to a selected, determined resonant frequency when said gas compressor is in operation.
The method of altering a resonant frequency in a gas compressor including a motor and a muffler in a generally spaced relationship with respect to said motor, comprising the steps of;
- mechanically linking adjustably said motor and said muffler;
- adjusting said mechanical linkage so as to alter the resonant frequency of said gas compression apparatus to a predetermined resonant frequency when said compression apparatus is in operation.
