Abstract
A housing for the bearing of a worm gear of the type used in steering gear devices of vehicles is provided with a cover plate having an annular groove or cavity into which the conical disc spring which bears on a ball bearing race can bend or bow in order to give it the freedom required for precise pretensioning or resilient compression against the radial face of the race.
Claims2
An arrangement for effecting a precisely determined axial force on a thrust bearing within a housing:
- comprising a housing having a bearing race therein;
- a cover on said housing;
- a conical ring-like spring having an edge compressed by said cover to effect axial force of the other edge on said bearing race;
- and an annular groove in said cover disposed to freely accommodate a bowed portion of said spring as it bows under compression, so as to maintain a precise force on said bearing by avoiding abutment between said bowed portion and said cover.
