Abstract
The utility model relates to a rare-earth permanent-magnetic belt pulley which uses magnetic repulsive force to overcome load impact force, composed of an inner shaft sleeve provided with a magnetic shifting block and the outer belt pulley of the magnetic shifting block. The outer belt pulley is movably sheathed on the inner shaft sleeve fixed with the extended part of a motor shaft; the outer belt pulley is connected with the belt of a load wheel, the magnetic shifting blocks of the outer belt pulley and the belt of a load wheel are alternatively arranged, and the adjacent shifting block ends have the same magnetic pole; accordingly, the belt pulley and the inner shaft sleeve are driven to synchronously rotate through the magnetic repulsive force among the shifting blocks. Simultaneously, the magnetic repulsive force can store balanced load impact, and the impact can be prevented from transferring to the motor; accordingly, the purposes of energy saving and motor protection can be obtained.
Description
The application relates to a kind of belt pulley that can absorb load impact power, especially a kind of rare earth permanent-magnet pulley that utilizes magnetic force balanced load impact force.
As everyone knows, belt pulley is the transmission component that connects load and motor, and the ordinary straps wheel is an integrative-structure, is connected by key with the motor shaft extension.When load has impact force to belt pulley (as loom, high velocity ram machine, air compressor etc.), this impact force will be passed to motor shaft by belt pulley, the output power of motor is strengthened, it is bad that working environment becomes, the reactive loss electric energy increases, can shorten the working life of motor, how eliminating or weakening impact load is a long-standing problem to the influence of motor.
The application's purpose is to disclose a kind of rare earth permanent-magnet pulley that can effectively absorb or cushion load to electromechanical shock power, and can strengthen the motor anti-seismic performance, reduces reactive loss, and using electricity wisely prolongs the motor purpose in working life.
Technological scheme is as follows: the application's belt pulley is made up of internal axle sleeve and exterior belt pulley, be fixed with magnetic shifting block on internal axle sleeve and the exterior belt pulley respectively, exterior belt pulley and magnetic shifting block thereof are actively socketed on the internal axle sleeve, its relative internal axle sleeve can be rotated back and forth, both magnetic shifting blocks are alternately on a vertical plane, between the adjacent shifting block certain clearance is arranged simultaneously, the magnetic pole of the abutting end of adjacent shifting block is identical, makes the repulsive force that is magnetic between the adjacent shifting block.By this magnetic repulsion force between the shifting block internal axle sleeve and exterior belt pulley relative fixed are in the same place just.
Here, internal axle sleeve can be fixedlyed connected with the motor shaft extension is supporting, exterior belt pulley can join by belt with loadwheel, when motor shaft drives the internal axle sleeve rotation, magnetic shifting block on the internal axle sleeve passes through the repulsive force to the magnetic shifting block of adjacent exterior belt pulley, drives belt pulley rotation synchronously and outside outputting power.But when load is given reverse impact power of belt pulley; this impact force must at first be subjected to the balance of magnetic repulsion force; the distance of the adjacent shifting block of impact force reverse compression; make belt pulley a counterrotating (asynchronous rotation) be arranged with respect to internal axle sleeve; impact force is absorbed storage; when impact force disappeared, magnetic repulsion force will make exterior belt pulley and shifting block reset again, and was synchronous with internal axle sleeve; because between internal axle sleeve and the exterior belt pulley is the magnetic force flexible fastening; therefore, impact force can not pass to motor by internal axle sleeve, thereby reaches antidetonation; eliminate impact force; the protection motor reduces reactive loss, the purpose of saving power.
Above-mentioned magnetic shifting block can be to constitute by inlaying rare earth permanent-magnetic material on the non magnetic shifting block.
Below in conjunction with embodiment's accompanying drawing, this application is described in further detail.
Fig. 1, Fig. 2 are the general construction schematic representation of this rare earth permanent-magnet pulley.
Fig. 3, Fig. 4 are the structural representations of exterior belt pulley.
Fig. 5, Fig. 6 are the structural representations of internal axle sleeve.
Referring to accompanying drawing, there is the shifting block 5,7 of two protrusions an end of exterior belt pulley 2, being coaxial line arranges, respectively inlay a rare earth permanent-magnetic material 4 on the shifting block respectively, an end of internal axle sleeve 3 has the shifting block 1,6 of two protrusions equally, also being coaxial line arranges, also respectively inlay a rare earth permanent-magnetic material 4 on it respectively, exterior belt pulley 2 is actively socketed on the internal axle sleeve 3 by bearing 9, the shifting block of the band magnet steel on it is criss-crossing alternately on a vertical plane, and unlikelyly deviate from by packing ring 10 and baffle ring 11 are fixing the end.Magnetic pole between the adjacent shifting block is identical, and making has a permanent magnetism repulsion between adjacent shifting block, and this magnetic repulsion force is an one with internal axle sleeve 3 and exterior belt pulley 2 flexible fastenings.Groove shape key 8 is arranged in the internal axle sleeve 3, can fix with the motor shaft extension.When driven by motor internal axle sleeve 3 rotates, the carrying magnetic shifting block 1,6 of internal axle sleeve 3, to drive shifting block 5,7 and exterior belt pulley 2 rotates synchronously by magnetic repulsion force, when load impact power, impact force will overcome magnetic repulsion force, make exterior belt pulley 2 and shifting block 5,7 relative internal axle sleeves 3 and shifting block 1,6 counterrotating displacements, with the impact force balance, after impact force disappeared, magnetic repulsion force made exterior belt pulley and shifting block 5,7 relative internal axle sleeve reset synchronization again.Therefore this impact force is not passed on the motor shaft, thereby reaches the purpose of antidetonation economize on electricity.
This belt pulley is applicable to that all have the rotation transmission of impact load.
