Abstract
The magnetic coupling of automatic adjustment permanent magnet axial location, comprises the installation sleeve be sleeved on load adapter sleeve, installation sleeve is set with rotating disk, rotating disk is inlaid with permanent magnet, and 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 one end is rotationally connected by rotating shaft and support plate, the permanent magnetism that support plate is fixedly connected on side covers, described rotating shaft is set with torsion spring, and the other end of strutting piece mutually leans with the permanent magnetism lid of opposite side under the effect of torsion spring.During high-speed cruising, strutting piece rotates and removes support, and as load is met unexpected, the air gap between each copper dish and permanent magnet becomes greatly, reduces the ability of transmitting torque in time, serves good protected effect, safe and reliable.
Description
Technical field
The utility model relates to a kind of magnetic coupling, particularly a kind of magnetic coupling of automatic adjustment permanent magnet axial location.
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.Spacing adjustment component is not had between two groups of magnetic induction torque-transmitting mechanisms when the magnetic coupling of this structure runs; as unexpected feelings in running; air gap between permanent magnet and copper dish can not change; can not reduce transmitting torque thereupon increasing air gap in time, automatic protection functions is unsatisfactory.
Summary of the invention
The purpose of this utility model be to provide that a kind of structure is simple, the spacing of two groups of magnetic induction torque-transmitting mechanisms can increase suddenly according to load and relatively reduce, between copper dish and permanent magnet air gap becomes greatly, the timely magnetic coupling reducing the automatic adjustment permanent magnet axial location of transmitting torque, overcome the deficiencies in the prior art.
The magnetic coupling of automatic adjustment permanent magnet axial location 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 one end is rotationally connected by rotating shaft and support plate, the permanent magnetism that support plate is fixedly connected on side covers, described rotating shaft is set with torsion spring, and the other end of strutting piece mutually leans with the permanent magnetism lid of opposite side under the effect of torsion spring.
The magnetic coupling of automatic adjustment permanent magnet axial location of the present utility model, when stopping and low cruise, under the leaning of strutting piece, keep relative distance between two groups of magnetic induction torque-transmitting mechanisms constant, the air gap simultaneously maintained between each copper dish and permanent magnet is constant.During high-speed cruising; under the influence of centrifugal force; the elastic force that now strutting piece overcomes torsion spring can rotate relative to rotating shaft; namely strutting piece is no longer played a supporting role, and as load is met unexpected, two groups of magnetic induction torque-transmitting mechanisms reduce relative distance; namely the air gap between each copper dish and permanent magnet becomes large; the ability of timely reduction transmitting torque, serves good protected effect, safe and reliable.
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.
Strutting piece 15 is provided with between two groups of magnetic induction torque-transmitting mechanisms, strutting piece 15 one end is rotationally connected by rotating shaft 17 and support plate 18, support plate 18 is fixedly connected on the permanent magnetism lid 10 of side, rotating shaft 17 is set with torsion spring 16, and the other end of strutting piece 15 mutually leans with the permanent magnetism lid 10 of opposite side under the effect of torsion spring 16.
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.
