Abstract
The invention discloses a magnetic shaft coupling. The magnetic shaft coupling comprises a shaft coupling body, upper and lower annular grooves are respectively formed at the upper and lower ends of the shaft coupling body, upper and lower magnetic steel seats are respectively mounted in the upper and lower annular grooves, four circular magnetic steel units are laid in the upper and lower magnetic steel seats uniformly, upper and lower circular grooves are respectively formed at the upper and lower ends of the center of the shaft coupling body, jeweled bearings are respectively laid in the upper and lower circular grooves, upper and lower thrust shafts are respectively mounted on the jeweled bearings in the upper and lower circular grooves, the upper and lower thrust shafts are connected with a shaft in an interference fit manner to form an integral body, the integral body is then pivoted to the upper and lower magnetic steel seats respectively to form an integral unit, and glands are fixed to the upper and lower ends of the shaft coupling body via screws respectively. The magnetic shaft coupling realizes novel magnetic transmission, is smooth in movement, low in friction force, low in wearing and wide in the speed regulation range, and is prevented from being stuck.
Description
Technical field
The present invention relates to magnetic transmission technical field, particularly relate to a kind of magnetic shaft coupling.
Background technology
Magnetic transmission is used for a kind of kind of drive in flowmeter, and transmission conventional in engineering has machine driving and magnetic transmission.Machine driving be by gear between engagement carry out transmission, the serious wear between gear and gear, very flexible, failure rate is high.Magnetic transmission be by magnet steel between the magnetic force of magnetic pole carry out transmission.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of magnetic shaft coupling.
The present invention is achieved by the following technical solutions:
A kind of magnetic shaft coupling, include shaft coupling main body, upper and lower cannelure is had at the upper and lower side of described shaft coupling main body, upper and lower magnet steel seat is separately installed with in upper and lower cannelure, upper and lower magnet steel seat is evenly inlaid with four circular magnet steel, upper and lower circular recess is had at the center upper and lower side of shaft coupling main body, all jewel bearing is inlaid with in the inside of upper and lower circular recess, in upper and lower circular recess, jewel bearing is provided with bottom stopper push shaft, on described bottom stopper push shaft, interference fit is connected with axle composition entirety respectively, rivet integrally with upper and lower magnet steel seat respectively again, gland is fixed with respectively by screw at the upper and lower side of shaft coupling main body.
The thickness of described circular magnet steel is 3mm.
Undertaken rubbing by thrust shaft and jewel bearing and by circular recess and magnet steel seat axis hole spacing, gland is connected with shaft coupling main body screw.Flowmeter in working order under, by the gear train of itself, moment is inputed to the magnet steel seat with gear and magnet steel, when lower magnetic steel seat with gear and magnet steel rotates, upper magnetic steel seat is rotated by magneticaction, and the signal received by transducer after output changes output display through transducer.To reach function of measuring.
When lower magnetic steel is rotated by gear driven, upper magnetic steel rotates thereupon, carries out transmission torsion.Carry out signal transmission to the display of table body by transmission, on-the-spot display can be realized and show on the spot.
Advantage of the present invention is: magnetic transmission of the present invention, stable movement, and frictional force is little, weares and teares little, can not cause stuck, and speed adjustable range is large, achieves Novel transmission.
