PHOTOELECTRIC ANGLE CONVERTER (ALTERNATIVES) Russian patent published in 2004 - IPC

FIELD: automation and computer engineering.

SUBSTANCE: proposed angle converter designed for analog-to-digital conversion of angular position of shaft into digital code to obtain digital information from controlled entities and its entering in digital control and computing machines is presented in two design alternates. Converter is characterized in that indicator disk is built integral with its holder which simplifies converter design, eliminates turn and offset of indicator disk carrying information channels relative to case under action of external factors such as vibrations, impacts, temperature fluctuations; indicator disk has base holes joined with guide cylinders which enhances functional capabilities of converter; spacer rings are fitted between indicator disk and holders of radiators and photodetectors which enhances stiffness of parts; adjusting screws are disposed in guide cylinders which ensures high precision of converter and enlarges its functional capabilities, for instance, ability of displacing indicator disk; flexible material is placed in gap to eliminate play during adjustments; adjusting screws are disposed in indicator disk plane which minimizes converter size and enables using it in small measuring systems.

EFFECT: simplified design, enhanced stiffness of component pats, enlarged functional capabilities of converter.
