Abstract
A method for producing a shaft grounding ring includes providing a shaft grounding ring having an annular main body and contact elements arranged on the main body. The contact elements are electrically conductive and plastic-based. The contact elements are configured to establish an electrically conductive sliding contact with a circumferential surface of a shaft or of a sleeve placed onto the shaft. The contact elements are elastically bendable such that the contact elements are configured to preload the electrically conductive sliding contact. Additionally, the method includes thermally preconditioning the shaft grounding ring before use.
