Abstract
The utility model discloses a brand-new electromagnetic friction clutch, which consists of an electromagnetic magnet, a clutch rotating disc, a friction disc and a flange disc. A magnetic isolation ring and a friction piece are arranged on the disc surface of the clutch rotating disc, the friction piece and the friction disc are opposite, and the friction disc and flange disc are flexible connected. The utility model adjusts the transmitted torque, realizes the non-reference differential rotation of a driving shaft and a driven shaft, provides a brand-new variety for the clutch, and explores a brand-new application field for the clutch. The utility model used in the tracking apparatus realizes close tracking, random tracking and other special functions.
Description
The utility model relates to a kind of clutch, specifically a kind of electromagnetic friction clutch.
Clutch can be realized being separated from each other and the power transmitting deice that combines as a kind of between drive unit and the operation mechanism, and the application in mechanical device is very general.Existing clutch generally all is to adopt the rigidity of parts such as key, tooth, groove to cooperate to realize clutch function, its objective is to be transmitting torque to greatest extent, the mechanical energy loss in the middle of reducing.Because what adopt is that rigidity cooperates, thereby the driving shaft that joins respectively with clutch and the rotating speed of driven axle be on all four, so the rotating speed adjustment of operation mechanism just can only be realized by the rotational speed regulation to drive unit.But under some occasion, need to realize the differential rotation of non-definite value of driving shaft and driven axle, or need the variable torque of transmission adjustable, then adopt devices such as existing clutch, speed changer then all can not reach above-mentioned requirements.
The purpose of this utility model just provides a kind of electromagnetic friction clutch, to overcome the deficiency of existing apparatus, realizes the specific function that rotating speed is variable, moment of torsion is adjustable.
The technical solution that the utility model adopted is: clutch is made up of electromagnet, clutch rotating disk, friction disk and flange plate, and magnetism resistent ring and friction plate are arranged on the card of clutch rotating disk, and friction plate is relative with friction disk, and friction disk is that elasticity is connected with flange plate.Driving shaft on the drive unit and clutch rotating disk are joined, and driven axle and flange plate in the operation mechanism join.Because the existence of magnetism resistent ring on the clutch rotating disk, with the blocking-up of the flux path on the clutch rotating disk, force the magnetic line of force that produces by electromagnet edge by the clutch rotating disk, get back to clutch rotating disk middle part through friction disk again, thus the formation magnetic loop.So just friction disk can be adsorbed onto on the card of clutch rotating disk, rely on the friction plate of relative friction disk one side setting on the clutch rotating disk and the frictional engagement of friction disk, transmit rotation torque.Change the hot-wire coil number of turn of electromagnet, perhaps change magnitude of voltage, can adjust the electromagnetism the suction-combining force, change the size of transmitting torque to the electromagnet power supply.After the electromagnet outage, friction disk is released, and under the return force function of spring sheet, friction disk is retracted flange plate one side, thereby disconnects the contact between master, the driven axle.In addition, because driven axle is to realize rotation by the friction torque that transmits between friction disk and the clutch rotating disk upper friction plate, thereby belong to the form of non-rigid connection between main, the driven axle, can realize relatively rotating, promptly when the driven axle rotational resistance of operation mechanism surpasses transmitting torque, the operation that throws switch will appear in driven axle, even turns to also and may change, and adapts to need of work under some special occasions with this.
The utility model is the size of can regulate institute transmitting torque both, can realize the differential rotation of non-definite value of driving shaft and driven axle again, for clutch series has increased a brand-new kind, opened up the whole new set of applications field of clutch, especially can use among some followup devices, can be implemented in operation mechanism under the situation of drive unit invariable rotary with closely the following of subsidiary device, servo-actuated with the irrealizable at all specific function of ordinary clutch such as stopping.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the card External view of friction disk.
Fig. 3 is the partial enlarged drawing of friction disk and flange plate Placement.
As shown in Figure 1, the electromagnet 6 in this device is the coils of packing in base, and coil can be one group, preferably has more than 2 groups, so that regulate the size of electromagnetic force.What join with electromagnet 6 is clutch rotating disk 2, has a circle magnetism resistent ring 1 that the edge of clutch rotating disk and the flux path at middle part are cut off on its card, makes it to form magnet short-cut path.Clutch rotating disk and magnetism resistent ring are connected to an integral body, to guarantee the reliable rotation of clutch rotating disk.The card middle part of clutch rotating disk 2 is provided with axle sleeve, is socketed in the center hole of electromagnet 6, in order to connect driving shaft.The card outside at clutch rotating disk 2 is bonded with non-metal friction plate 7.Relative with clutch rotating disk 2 is friction disk 3, and the card of itself and clutch rotating disk keeps micro-gap.Flange plate 8 joins with friction disk 2 elasticity, and its Placement is between friction disk 3 and flange plate 8 spring sheet 4 to be arranged as shown in Figure 3, and rivet 5 is riveted on spring sheet 4 respectively on friction disk 3 and the flange plate 8.Rivet 5 can have 6 or more, and by shown in Figure 2, cross-distribution is distinguished riveted spring sheet and flange plate on a certain circumference of card, and spring sheet and friction disk.Thereby make flange plate and friction disk rely on spring sheet to realize that elasticity is connected.Promptly when electromagnet 6 outages, rely on the return elastic force of spring sheet 4, friction disk 3 is withdrawn into flange plate 8 one sides, make it to disengage with clutch rotating disk 2.Card middle part at flange plate 8 also is provided with axle sleeve, in order to connect the driven axle in the operation mechanism.
