Encoder device and apparatus for gapping and centering an encoder device

Abstract

An encoder device includes: a housing; a hub arranged in the housing, the hub arranged to carry an encoder disk, the hub rotatable in the housing; and a gapping and centering device carried by the housing and including a slide that is movable between a first position and a second position. The slide in the first position is arranged to urge the hub into a predetermined axial and radial position relative to a portion of the housing, and the slide in the second position is arranged to permit axial and radial movement of the hub. The slide is arranged on an axial side of the housing opposite to an axial side on which the housing is to be mounted to a device to be measured, and the slide in the first position and in the second position does not extend beyond a radial periphery of the housing.
