Product Announcement from Borrelly Spring Washers

Belleville Spring Washer made of Inconel-Image

A manufacturing process which enables to increase deflections and loads in elastic deformation range at high temperatures. Qualification in environmental chamber.

Problem to be solved: Preload a variable high speed geometry turbocharger, high temperature

Constraints: Austere environment, stresses in dynamic, very high temperature variations (thermal cycling from -40°C to +790°C), very small space available, high energy levels.

Solution: Study and design of a Belleville type spring washers stacking made in a Nickel base super alloy Inconel type with optimization of the points of stress concentration to guarantee a place in operation without slackening or failure.

Borrelly added value: A manufacturing process which enables to increase deflections and loads in elastic deformation range at high temperatures. Qualification in environmental chamber.
