エンコーダ付車輪支持用転がり軸受ユニット
Document Type and Number:
Japanese Patent JP5772905
Kind Code:
B2
Abstract:
Construction is achieved that is able to prevent strain deformation in the axial direction of a flat plate section 21 of a cover 19a when a cylinder section 20 of the cover 19a, which covers the opening on the inside end in the axial direction of an internal space where an encoder 1 is located, is fitted into and fastened to the inside end section in the axial direction of an outer ring 7. A non-contact section 26a is formed all the way around the inside end section in the axial direction of the cylinder section 20 such that the outer diameter is smaller than the inner diameter of the inside end section in the axial direction of the outer ring, and the dimension L 26 in the axial direction is two times or more the thickness dimension t 19 of a plate member of the cover 19a. With the cover 19a fitted into the inside end section in the axial direction of the outer ring 7, only the portion of the cylinder section 20 that is nearer the outside in the axial direction than the non-contact section 26a is substantially fitted into the inside end section in the axial direction of the outer ring 7 with an interference fit.
