Technical field
The utility model relates to a kind of permanent magnetism transmission device that has grinding disk, and device promotes grinding disk adhesive transmission through centrifugal steel ball near rated speed, can eliminate the intrinsic slippage of permanent magnetism transmission device, plays energy-conserving action.
Background technology
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 the utility model provides a kind of permanent magnetism transmission device that has grinding disk, and this installs when the even running of contact Permanent Magnetic Gear transmission mechanism total power, can effectively eliminate slippage, avoids the conductor disc heating.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of permanent magnetism transmission device that has grinding disk comprises initiatively steel disk, driven steel disk, conductor disc, permanent magnetism dish, and conductor disc and permanent magnetism dish are oppositely arranged; It is characterized in that, outside conductor disc, be equipped with and decide frictional disk, outside the permanent magnetism dish, be equipped with the dynamic friction dish; The outside of said driven steel disk arranges evenly that by circumferencial direction several are provided with centrifugal push module, and when the rotating speed of permanent magnetism dish during near rated speed, centrifugal push module produces centrifugal force; Promote the dyanainic friction dish and decide the grinding disk adhesive; Make the permanent magnetism transmission device carry out the transition to the grinding disk Contact Transmission, make the rotating speed of driven shaft and driving shaft synchronous, eliminate slippage from the noncontact transmission of permanent magnetism.
Described dynamic friction dish and dynamic friction disc holder are assembled together, and are connected with centrifugal push module through 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, back-moving spring, back-moving spring lock screw; 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 dynamic friction dish, connects through guide block pull bar screw; One end of back-moving spring is fixed through lock screw, and the other end is connected with guide block pull bar screw.
Compared with prior art, the beneficial effect of the utility model is:
The transmission advantage that has kept the permanent magnetism drive mechanism when the total power even 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 back-moving 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 noncontact transmission of permanent magnetism; The 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 back-moving spring; The dyanainic friction dish with decide grinding disk disengagement, at this moment, contact Permanent Magnetic Gear transmission mechanism is started working once more; Drive load is rotated, and realizes the purpose of protection motor.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explain:
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, the spacing of deciding grinding disk 1 and dyanainic friction dish 4 is more than or equal to the minimum spacing 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 receives 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 fast more; The thrust of 10 pairs of surface cylinder jacking blocks 9 of centrifugal steel ball is big more; 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 back-moving 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 back-moving 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, drive load end rotating speed reaches the nominal operation rotating speed, gets into grinding disk again and drives operating mode.
