Description

Technical Field

[0001] This utility model relates to the field of disc springs, specifically a high-strength disc spring device for drilling rigs. Background Technology

[0002] Disc springs are conical discs that can be used individually, in series, or in parallel. They bear static or dynamic loads acting axially at their upper inner and lower outer edges. When compressed, they deform until flattened, storing energy as a live load. When necessary, they automatically convert into the additional compressive load required for sealing, reducing the need for continuous tightening of gaskets and packings. However, existing disc spring devices suffer from poor structural strength, resulting in insufficient service life.

[0003] To solve the above problems, a high-strength disc spring device for drilling rigs is hereby proposed. Utility Model Content
