Description
Technical field
The present invention relates to a kind of permanent magnetism transmission device that has grinding disk, device promotes grinding disk adhesive transmission by centrifugal steel ball near rated speed, can eliminate the intrinsic slippage of permanent magnetism transmission device, plays energy-conserving action.
Background technique
At present, in the permanent magnetism transmission device, driving shaft and driven shaft have minimum 2% slippage.The existence of slippage is the basis of permanent magnetism transmission, the loss that has also brought energy simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of permanent magnetism transmission device that has grinding disk, this installs when the smooth running of contact Permanent Magnetic Gear transmission mechanism full power, can effectively eliminate slippage, avoids the conductor disc heating.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of permanent magnetism transmission device that has grinding disk, comprise initiatively steel disk, driven steel disk, conductor disc, the permanent magnetism dish, conductor disc and permanent magnetism dish are oppositely arranged, it is characterized in that, outside conductor disc, be equipped with and decide friction disk, outside the permanent magnetism dish, be equipped with the kinetic friction dish, the outside of described driven steel disk arranges evenly that by circumferencial direction several are provided with centrifugal push module, when the rotating speed of permanent magnetism dish during near rated speed, centrifugal push module produces centrifugal force, promotes the dyanainic friction dish and decides the grinding disk adhesive, makes the permanent magnetism transmission device carry out the transition to the grinding disk Contact Transmission from the non-contact transmission of permanent magnetism, make rotating speed and the driving shaft of driven shaft synchronous, eliminate slippage.
Described kinetic friction dish and kinetic friction disc holder are assembled together, and are connected with centrifugal push module by the surface cylinder guide block.
Described centrifugal push module is made up of surface cylinder jacking block, centrifugal steel ball, guide block pull bar screw, Returnning spring, Returnning spring locking nut, centrifugal steel ball is positioned at the steel ball raceway and can slides at the steel ball raceway, one side of steel ball raceway is provided with the surface cylinder jacking block, the inclined-plane of surface cylinder jacking block contacts with surface cylinder guide block inclined-plane on the kinetic friction dish, connects by guide block pull bar screw; One end of Returnning spring is fixed by locking nut, and the other end is connected with guide block pull bar screw.
Compared with prior art, the invention has the beneficial effects as follows:
The transmission advantage that has kept the permanent magnetism drive mechanism when the full power smooth running, can be eliminated slippage.When the rotating speed of permanent magnetism dish near rated speed the time, the centrifugal force that centrifugal steel ball produces will overcome the elastic force of the intrinsic frictional force of system and Returnning spring, promote the dyanainic friction dish and decide the grinding disk adhesive, make system carry out the transition to the grinding disk Contact Transmission from the non-contact transmission of permanent magnetism, rotating speed and the driving shaft of driven shaft are synchronous, eliminate slippage, at this moment owing to there is not the existence of slippage, contact Permanent Magnetic Gear transmission mechanism is no longer worked, and conductor disc can not generated heat yet again.
When load occur suddenly transshipping or stuck situation under; the rotating speed of driven shaft descends rapidly; the centrifugal force that centrifugal steel ball produces is not enough to keep the attracting state of grinding disk; under the effect of Returnning spring; the dyanainic friction dish with decide grinding disk disengagement, at this moment, contact Permanent Magnetic Gear transmission mechanism is started working again; the drive load is rotated, and realizes the purpose of protection motor.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
See Fig. 1-Fig. 6, a kind of permanent magnetism transmission device that has grinding disk comprises active steel disk 3, driven steel disk 6, conductor disc 2, permanent magnetism dish 11, decides grinding disk 1, dyanainic friction dish 4, centrifugal push module 8.Conductor disc 2 is oppositely arranged with permanent magnetism dish 11, decides grinding disk 1 and is installed on the active steel disk 3, at the outer shroud of conductor disc 2.Dyanainic friction dish 4 combines with dyanainic friction disc holder 5, surface cylinder guide block 7, is installed on the driven steel disk 6 outer shroud of permanent magnetism dish 11.Under static situation, decide the spacing of grinding disk 1 and dyanainic friction dish 4 more than or equal to the minimum separable of permanent magnetism dish 11 with conductor disc 2.
In system high-speed rotation, when the rotating speed of permanent magnetism dish 11 during near rated speed, centrifugal steel ball 10 is subjected to action of centrifugal force and moves to the direction away from the axle center, and surface cylinder jacking block 9 is produced thrusts.The rotating speed of system is more fast, the thrust of 10 pairs of surface cylinder jacking blocks 9 of centrifugal steel ball is more big, can overcome when thrust after the elastic force and the frictional force between surface cylinder jacking block 9 and the surface cylinder guide block 7 of Returnning spring 13, surface cylinder jacking block 9 just continues to move to centrifugal direction along steel ball raceway 16, promotes surface cylinder guide block 7 and drives dyanainic friction dishes 4 near deciding grinding disk 1 and being pulled together.System carries out the transition to " work of permanent magnetism driving+grinding disk " from " permanent magnetism driving work ", in the time of driven steel disk 6 and active steel disk 3 synchronization, becomes the grinding disk transmission fully.
When the load end of system produced overload suddenly, the rotating speed of load end can descend suddenly, and the thrust of 10 pairs of surface cylinder jacking blocks 9 of centrifugal steel ball reduces, under the effect of Returnning spring 13, dyanainic friction dish 4 with decide grinding disk 1 disengaging and reset.At this moment, permanent magnetism drives the work that restarts, and along with system load recovers normal, drives the load end rotating speed and reach the nominal operation rotating speed, reenters grinding disk and drives operating mode.
