Description
Technical field
The utility model relates to the photoelectric coding technical field, is specifically related to a kind of incremental optical-electricity encoder.
Background technology
Encoder (Encoder) is a kind of of transducer (Sensor) class, be mainly used to detect speed, position, angle, distance or the counting of mechanical movement, except being applied in industrial machine, the control of many motor as servo motor, BLDC servo motor all need be equipped with encoder for motor controller as the detecting of commutation, speed and position, so range of application is quite extensive.According to detecting principle, encoder can be divided into optical profile type, magnetic-type, induction type and condenser type.According to its scale method and signal output form, be divided into incremental encoder and absolute type encoder.The optical grating diffraction principle of utilizing photoelectric encoder realizes displacement-digital conversion, and it is a kind of light harvesting, mechanical, electrically is the digitlization checkout gear of one.Nearly 10 in the past few years, in industries such as pharmacy, food, printing, tobacco, machineries, obtained using widely in numerous areas such as Digit Control Machine Tool, robot, radar, electro-optic theodolite, ground control's instrument, high precision closed loop governing system, servo system.Photoelectric encoder can be defined as: a kind of opto-electronic conversion of passing through, will transport to the machinery on the axle, the transducer that the geometric displacement amount converts pulse or digital quantity to, and it is mainly used in the detection of speed or position (angle).Typical photoelectric encoder is made up of code-disc (Disk), detection grating (Mask), photoelectric switching circuit (comprising light source, light-sensitive device, signaling conversion circuit), mechanical part etc.Existing photoelectric encoder resolution is lower, precision is not high, volume is big, working service is inconvenient.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of resolution height, precision height, simple in structure, volume is little, use is reliable, the incremental optical-electricity encoder that is easy to safeguard.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of incremental optical-electricity encoder, comprise shell, the shell internal fixation has positioning body, it is characterized in that: the O RunddichtringO is equipped with in the junction of described shell and positioning body, and described positioning body connects main shaft by bearing, and described shell inner main axis one end is provided with two PCB circuit boards, between two PCB circuit boards code-disc is housed, the PCB circuit board in described code-disc left side is equipped with light-sensitive element, on the PCB circuit board on code-disc right side light source is housed, and described shell upper is connected with connector.
Described bearing is a duplex bearing.
