Abstract
A waterproof encoder belongs to encoders and comprises a sealing cover plate, a magnet disc, a shaft angle encoder, a sealing cylinder and a waterproof thread guider. The sealing cover plate is connected to one end of the sealing cylinder, the waterproof thread guider is disposed at the other end of the sealing cylinder, the magnet disc and the shaft angle encoder are mounted in the sealing cylinder, the magnet disc is connected with a rotating shaft of the shaft angle encoder, an output wire of the shaft angle encoder realizes output via the waterproof thread guider, and a magnet disc, which corresponds to the magnet disc inside the sealing cylinder, is disposed outside the sealing cylinder. The waterproof encoder has the advantages that the shaft angle encoder in a sealing cavity is completely isolated from an external environment, can bear 10Mpa pressure without leakage, can be applied to underwater and explosive-proof environments, high-corrosion gas environments and wet environments, and is more reliable in sealing performance compared with an encoder in a sealing ring scheme.
Description
Technical field
The utility model relates to a kind of scrambler, particularly a kind of waterproof encoder.
Background technology
Shaft-position encoder is widely used as angular displacement sensor.But as particular application, as high humidity environment, under water, corrosive gas, explosion-proof environment, just be subjected to certain restriction.Practical shaft-position encoder adopts the Simmer ring method to realize the measurement usefulness of angular displacement more under above-mentioned environment at present.Its rubber seal is aging easily, between rubber seal and rotating shaft sliding resistance big, under big pressure, still have a spot of harmful gas or liquid to enter in the scrambler cavity space along the slit between rubber seal and the rotating shaft, influence the operate as normal of scrambler.
The utility model content
The purpose of this utility model is that a kind of waterproof encoder will be provided, it is aging easily to solve rubber seal, sliding resistance is big between rubber seal and rotating shaft, under big pressure, still have a spot of harmful gas or liquid to enter in the scrambler cavity space, influence the problem of scrambler operate as normal along the slit between rubber seal and the rotating shaft.
The purpose of this utility model is achieved in that this scrambler comprises seal cover board, magnet disk, shaft-position encoder, sealed cylindrical and waterproof wire-threading device, end at sealed cylindrical is connected with seal cover board, the other end at sealed cylindrical has the waterproof wire-threading device, magnet disk and shaft-position encoder are installed in the sealed cylindrical, the magnet disk is connected with the rotation axis of shaft-position encoder, the output line of shaft-position encoder has a corresponding magnet disk by the output of waterproof wire-threading device outside sealed cylindrical with in the sealed cylindrical.
Described magnet disk comprises axle, non-magnetic conduction supporter and magnet, and non-magnetic conduction supporter is discoid, at the center of non-magnetic conduction supporter axle is arranged, and is evenly equipped with magnet on the disk of non-magnetic conduction supporter.
Described shaft-position encoder is photoelectric encoder or contact scrambler.
Beneficial effect, owing to adopted such scheme, shaft-position encoder is sealed in the cylindric cavity, a disk that studs with several neodymium iron boron magnetic bodies is arranged on its rotating shaft front end, the S utmost point or the N utmost point were all towards an end face when magnet was inlayed, magnet rotary disk scrambler rotates thereupon, and scrambler has data output.Have a same disk that studs with several neodymium iron boron magnetic bodies parallel with its face in cylindric seal chamber corresponding end outside, the N utmost point or the S utmost point and made two magnet disk magnetic poles reach mutually the purpose that attracts on the contrary all towards an end face when magnet was inlayed.Separate by the annular seal space body wall between two magnets, outer edge magnet disk has certain distance not contact with the annular seal space body wall, outer edge magnet disk links to each other with tested article for rotation, testee rotates, under the magneticaction of the disk of inside and outside edge magnet, the disk of interior edge magnet rotates synchronously, has driven the scrambler rotation, and encoder data is exportable.It is aging easily to have solved rubber seal, sliding resistance is big between rubber seal and rotating shaft, under big pressure, still have a spot of harmful gas or liquid to enter in the scrambler cavity space along the slit between rubber seal and the rotating shaft, influence the problem of scrambler operate as normal, reached the purpose of this utility model.
Advantage: the shaft-position encoder in the seal chamber has been accomplished fully and external environment condition is isolated, the pressure that can bear 10Mpa can seepage, has solved under water, the problem of explosion-proof environment, severe corrosive gaseous environment, wet environment encoder applies.More reliable than O-ring seal scheme airtight performance.
