专利汇可以提供Rotary regenerator for gas turbine engines专利检索，专利查询，专利分析的服务。并且A rotary regenerator for gas turbine engines, which includes a heat-accumulator in a disc form which is rotatable with a rotary shaft, an externally toothed ring gear which is positioned concentrically and at a slight spacing from the heat-accumulator and which is driven to rotate the heat-accumulator and a driving means mating with the ring gear to drive it. Aligned recesses are formed circumferentially equidistantly in outer and inner rims of the heat-accumulator and the ring gear, respectively, and leaf springs are mounted in the aligned recesses to press the heataccumulator and the ring gear against each other to support the former resiliently by the latter. Mechanical shocks and impact created by a driving force transferred from the ring gear to the heat-accumulator are absorbed by the leaf springs so that the heat-accumulator made of a material susceptible to shocks and impact is protected therefrom.，下面是Rotary regenerator for gas turbine engines专利的具体信息内容。

权利要求

1. In a rotary regenerator having a rotatable disc-type heataccumulator: driving means for rotationally driving said rotary regenerator about an axis of rotation comprising means defining a plurality of first arcuate recesses disposed equidistantly along the circumference of said disc-type heat-accumulator and extending parallel to said axis of rotation, an externally toothed ring gear positioned concentrically around said heataccumulator in spaced-apart relationship therewith and having along its inner surface means defining a plurality of second recesses corresponding to said first recesses in number and position, each of said second recesses having therein means defining a pair of grooves extending parallel to said axis of rotation and separated by a land projecting toward said heataccumulator, and a plurality of spring means disposed between respective pairs of said first and second recesses and each comprising a pair of rounded end portions fitted respectively in said grooves of its associated second recess and a central portion fitted in its associated first recess and extending over the associated land for resiliently supporting said heataccumulator by said ring gear.

2. A rotary regenerator according to claim 1, in which each of said spring means comprises a leaf spring.

3. A rotary regenerator according to claim 2, in which said grooves and said land within each second recess are formed by a T-shaped pad fitted within said second recess which has a rectangular configuration.

4. A rotary regenerator according to claim 3, in which said pad comprises a unitary member.

5. A rotary regenerator according to claim 4, in which each said pad is integral with said ring gear.

6. In a rotary heat-accumulator regenerator for use with a gas turbine engine: a rotary heat-accumulator disc; an annular member disposed concentrically around said disc and having an inner surface spaced-apart from the disc circumference; drive means for rotationally driving said annular member; and means for transmitting the rotary movement of said annular member to said disc to effect rotation of said disc comprising means spaced circumferentially around the circumference of said disc defining a first plurality of arcuate recesses, means spaced circumferentially around said inner surface defining a second plurality of recesses in said annular member each spaced from one of said arcuate recesses and defining therewith a set of opposing recesses, an abutment member having opposite side portions disposed in each of said second plUrality of recesses and projecting towards said disc, and a plurality of springs respectively disposed in each set of opposing recesses coacting together to resiliently support said disc within said annular member, each spring having a curved middle portion extending into its associated arcuate recess and abutting against said disc and a pair of arcuate end portions each abutting against opposite side portions of its associated abutment member; whereby rotation of said annular member is transmitted through said springs to effect rotation of said disc.

7. A rotary heat-accumulator regenerator according to claim 6; wherein each said spring comprises a leaf spring disposed in each set of opposing recesses and compressed between said annular member and said disc.

8. A rotary heat-accumulator regenerator according to claim 6; including a pad mounted within each of said second recesses and having one of said abutment members connected thereto.

9. A rotary heat-accumulator regenerator according to claim 8; wherein each pad and abutment member comprise a unitary structure.
