Title:
SHAFT-ENCODER
Document Type and Number:
Japanese Patent JPS58225318
Kind Code:
A
Abstract:
An optical shaft encoder (10) achieves, by its construction, both axial and radial alignment. This is achieved by first securing to a housing (30) by a latch, a mounting plate (15) which is spaced a predetermined distance from the housing (30). A rotatable encoder disc (40), having a conically shaped hub (46) is placed in an aperture (36) in the housing (30). The assembly is pushed onto the motor shaft (12), and the disc (40) is secured to the shaft (12). Plate (15) is then attached to motor case (13) and housing (30) rotated. This moves housing (30) into an abutting relationship with plate (15) and spaces housing (30) the predetermined distance from disc (40) which is thus both axially and radially positioned.
