Description
Technical field
The utility model relates to a kind of sensor, specifically a kind of high protection rotary encoder.
Background technology
Along with the development of China's economy and the progress of science and technology, rotary encoder has become the topmost high-acruracy survey product of industrial control field.
Rotary encoder is the speed displacement sensor integrating light, mechanical, electrical technology.Rotary encoder, by opto-electronic conversion, can convert the mechanical quantity such as the angular displacement of output shaft, angular velocity to corresponding electric pulse with digital output.Have volume little, lightweight, wide in variety, function is complete, and frequency response is high, and resolution characteristic is high, and moment is little, and consume energy the features such as low, stable performance, reliable long service life.
From market angle, the requirement of different market to scrambler is not quite similar, the requirement scrambler such as had wants precision higher, some requirement scramblers have stronger barrier propterty, what have then requires that scrambler will have good integrated opening, and what have is then less to the volume requirement of scrambler, and this just requires that on market, the kind of encoder product is abundanter, the market segments definitely, are suitable for the client of various demand type.
The rotary encoder structure used in the market is primarily of bearing, and main body, the compositions such as axle jump ring, general degree of protection is IP65, and degree of protection is low, cannot meet client to the requirement under rotary encoder particular surroundings.
Summary of the invention
The purpose of this utility model to provide a kind of simple and reasonable, and Installation and Debugging are convenient, low cost, the high protection rotary encoder that production efficiency is high, barrier propterty is strong.
The purpose of this utility model realizes like this, this rotary encoder comprises main shaft, encoder main body, single-groove grooved ball bearing, LED uviol lamp, lamp socket, determine grating, dynamic grating, Waterproof connector of cable, export cable, six window photoelectric cells, scrambler shell, processing of circuit plate, hollow copper post, jump ring, dynamic grating seat, O shape rubber seal II, circlip for shaft, rotary shaft lip seal, it is characterized in that: it also comprises an O shape rubber seal I for enhanced leaktightness effect, described encoder main body is inner, seal groove is processed with between two single-groove grooved ball bearings, described O shape rubber seal I is arranged in seal groove, described O shape rubber seal I closely cooperates with main shaft and encoder main body.
The utility model has the following advantages and good effect:
1, the utility model by prior art, body interior structure is improved, and reconfiguring, realizing secondary seal at interiors of products, having broken the conventional seals structure of rotary encoder in the past by being arranged on outside hermetically-sealed construction.
2, the utility model adds internal seal structure on the basis of original outer seal structure, solves the easy sepage phenomenon of rotary encoder main shaft wall in the past, enhanced leaktightness effect greatly.Through experimental test, main axle structure partial protection grade can reach IP67, meets the requirement of client to rotary encoder permanent protective property energy.
3, the utility model compact conformation, volume is little, and Installation and Debugging are simple, considerably reduce sealing cost, and rotary encoder external structure is constant simultaneously, facilitates client normally to use, and cost-savingly improves production efficiency.
