Description
Technical field
The utility model relates to a kind of magnetic coupling, particularly a kind of magnetic coupling limiting air gap change.
Background technology
Existing magnetic coupling comprises the installation sleeve be sleeved on load adapter sleeve, and installation sleeve is set with rotating disk, and rotating disk is inlaid with permanent magnet, and the copper dish matched with permanent magnet is fixed on steel disk, and the side of permanent magnet has permanent magnetism lid to be connected with rotating disk; Installation sleeve, rotating disk, permanent magnet, copper dish, steel disk, permanent magnetism lid are two groups, form the magnetic induction torque-transmitting mechanisms of two groups of symmetries.Do not have support component between two groups of magnetic induction torque-transmitting mechanisms when the magnetic coupling of this structure runs, changing appears in air gap between permanent magnet and copper dish sometimes, affects transmission effect.
Summary of the invention
The purpose of this utility model is to provide the magnetic coupling that a kind of structure is simple, the spacing of two groups of magnetic induction torque-transmitting mechanisms keeps constant, that transmission effect is good limited to the air gap of constant, between permanent magnet and copper dish air gap to change, and overcomes the deficiencies in the prior art.
The magnetic coupling limiting air gap change of the present utility model, comprise the installation sleeve be sleeved on load adapter sleeve, installation sleeve is set with rotating disk, rotating disk is inlaid with permanent magnet, the copper dish matched with permanent magnet is fixed on steel disk; There is the permanent magnetism lid be fixedly connected with rotating disk the side of permanent magnet; Described installation sleeve, rotating disk, permanent magnet, copper dish, steel disk, permanent magnetism lid are two groups, form the magnetic induction torque-transmitting mechanisms of two groups of symmetries, strutting piece is provided with between two groups of magnetic induction torque-transmitting mechanisms, described strutting piece is clipped between two permanent magnetism lids, wherein one end and the permanent magnetism lid of side are for being fixedly connected with, and the permanent magnetism lid of the other end and opposite side is for mutually to lean.
The magnetic coupling limiting air gap change of the present utility model, owing to being provided with strutting piece between two groups of torque transfer member, keep its spacing constant, the air gap simultaneously maintained between each copper dish and permanent magnet is constant, ensure that moment of torsion transmission effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: 14 is load adapter sleeve, and load adapter sleeve 14 is set with installation sleeve 12, and on installation sleeve 12, cover is fixedly equipped with rotating disk 11, and rotating disk 11 is inlaid with permanent magnet 7, and the copper dish 8 matched with permanent magnet 7 is fixed on steel disk 6; The permanent magnetism lid 10 be fixedly connected with by screw with rotating disk 11 is provided with outside permanent magnet 7.Installation sleeve 12, rotating disk 11, permanent magnet 7, copper dish 8, steel disk 6, permanent magnetism lid 10 are two groups, form the magnetic induction torque-transmitting mechanisms of two groups of symmetries.
Between two groups of magnetic induction torque-transmitting mechanisms, be provided with strutting piece 15, strutting piece 15 is clipped between two permanent magnetism lids 10, wherein between one end and the permanent magnetism lid 10 of side for being fixedly connected with, the permanent magnetism lid 10 of the other end and opposite side is for mutually to lean structure.Strutting piece 15 keeps the spacing of two groups of torque transfer member constant.
Two groups of magnetic induction torque-transmitting mechanisms are positioned at case, and case is made up of two parallel steel disks 6 and cylindrical shell 5, and the periphery of the steel disk 6 that two end peripheries of cylindrical shell 5 are parallel with two respectively connects, and form a closed housing.Wherein be bolted to connection between the steel disk 6 of side and motor adapter sleeve 3, the inner hole sleeve of the steel disk 6 of opposite side is contained in outside load adapter sleeve 14, is provided with gap 13 between the endoporus of steel disk 6 and load adapter sleeve 14.The outside of two steel disks 6 is distributed with heating panel 9.Be furnished with limited cover 2 in the inner termination of load adapter sleeve 14, be provided with caging bolt 1 in the central hole of limited cover 2.
During installation, motor adapter sleeve is sleeved on the output shaft of motor, and by the fastening location of fastening bolt on motor adapter sleeve.Load adapter sleeve 14 is sleeved on bearing axle, and caging bolt 1 is connected with the screwed hole of centre of bearing axle termination, makes limited cover 2 be pressed on bearing axle, carries out axial limiting.Motor can rotate by drive motor adapter sleeve 3, and steel disk 6, cylindrical shell 5, steel disk 8 rotate thereupon, and under magnetic strength effect, permanent magnet 7, rotating disk 11, installation sleeve 12 rotate thereupon, thus band dynamic load adapter sleeve 14 and bearing axle rotate.
