A device for aligning a motor shaft coupled to an input shaft supported by a bearing in a driven device, comprising a nut adapted for mounting on the driven device and a washer adapted for mounting on the bearing. The nut has an inner edge, an outer edge and a bottom surface having a concave spherical curvature. The washer has an upper surface with a convex spherical curvature corresponding to the concave spherical curvature of the nut. The spherical curvature of the washer has sufficient clearance for sliding against the spherical curvature of the nut. When the nut is mounted to the driven device and the washer is mounted to the bearing, the spherical surfaces of the nut and washer mate. The spherical surface of the washer can slide against the spherical surface of the nut to compensate for angular stresses on the shaft and maintain precise alignment of the motor shaft at all times. The invention also comprises a gearbox having the alignment device mounted therein.

Alignment device

A gearhead with an axially-extending input shaft connected to a motor shaft. A pinion gear and bearing assembly is adapted to connect to the motor shaft. The pinion gear is rotatably and sealably mounted to a recessed mounting surface of the housing to reduce noise, prevent entry of dirt and dust and provide a floating connection. The mounting is achieved with a double-sealed bearing which is configured to float with respect to the housing so that a high tolerance connection is maintained between the pinion gear and the gearhead while accommodating motor shaft misalignment. The invention also relates to a method for mounting the motor shaft onto the gearhead by inserting the motor shaft into the input pinion gear, securing the gearhead to the motor and clamping the input pinion gear to the motor shaft.
