Heavy load absolute type multi-ring resolving encoder

Abstract

The invention discloses a heavy load absolute type multi-ring resolving encoder, comprising an input shaft, a high-speed sealing ring, a heavy load labyrinth bearing cap; a heavy load bearing support, a heavy load bearing, a heavy load casing; a resolving base; a resolving stator, a resolving rotor, a resolving bearing cap, a precision bearing, a ring-number sending disk, a multi-ring counter PCB board, an RD connecting wire, an RD intelligent decoder PCB board, a data output PCN board, a bearing support O-shaped sealing ring, a bearing cap O-shaped sealing ring, an insulating shaft and a grounded braid. According to the invention, by perfectly combining resolver with microprocessor decoding chip and heavy load structure, the heavy load absolute type multi-ring resolving encoder which completely overcomes all the deficiencies existing in photoelectric encoder is formed with the characteristics of small size, good integration, high reliability and high precision. Compared with the photoelectric encoder, the heavy load absolute type multi-ring resolving encoder is especially prominently superior in position / speed feedback systems requiring high precision and high reliability.

Description

technical field [0001] The invention belongs to the field of automatic measurement and relates to an industrial detection technology. More particularly, it can provide high-reliability and high-precision absolute, incremental and analog angle position data to various automation systems. It can be used to measure the shaft angular position and speed in various occasions, especially suitable for various heavy-duty equipment and has a high-end interface. Background technique [0002] At present, high-precision heavy-duty photoelectric encoders are widely used in industrial sites of various heavy-duty equipment. Photoelectric encoders convert the input shaft angle position information into corresponding digital codes through photoelectric conversion. The photoelectric encoder is mainly composed of a photoelectric code disc, a grating, an LED photoelectric conversion tube and a conversion circuit. There are three main materials for photoelectric code discs: glass, plastic, and m...
