Abstract
The utility model relates to an electric vortex speed reducer, which mainly comprises a rotor assembly and a stator assembly; the stator assembly includes a fixed body and a fixed support, and the fixed support is tightly fixed with the fixed body via fixing screws. The periphery of the fixed support is provided with a plurality of electromagnetic devices; the rotor assembly comprises magnetic disks, a rotating body and radiators; the rotating body is tightly fixed on the shaft body, and the magnetic disk is in the shape of a cylinder. The magnetic disk is tightly fixed on the rotor via attachment screws, and the shaft body passes through the middle of the fixed support and is connected with bearing provided on the fixed body. The magnetic disk is sheathed with the outside of each electromagnetic device and makes air gap remain between the magnetic disks and the poles of the electromagnetic devices. The utility model has good decelerating effect and avoids the damaging effect for machines; the dissipation heat can be emitted into air via the radiators outside of the disk; thus the service life of the speed reducer can be prolongated.
Description
Technical field
Various machineries such as automobile are carrying out glancing impact, the capital produces very big force of inertia, and this force of inertia has very big destructive effect to machinery, in order to reduce this destructive effect as far as possible, mechanically just must be equipped with retarder, what the utility model was invented is a kind of current vortex retarder that does not have the mill sassafras.
Background technology
Existing current vortex retarder, because armature is made up of two rotating disks, and be located at the both sides of stator assembly respectively, when armature is subjected to magnetic action, because the endplay between uncontrollable good rotor assembly and stator assembly rubs so often cause between armature and the stator assembly, thereby causes magnet short-cut path, when serious even stuck phenomenon can occur, cause unnecessary accident or unknown losses.
Summary of the invention
The purpose of this utility model is to design a kind of later-model current vortex retarder at the shortcoming of existing product, it is that the force direction that is subjected to armature changes over radial force by axially loaded, like this, produce at coil under the situation of identical magnetic force, just can reduce the friction between armature and stator assembly, also just avoid the generation of accident.
The utility model is realized as follows: the utility model mainly is made up of an armature and a stator assembly, and stator assembly is fixed, and armature is to rotate along with axis body.Described stator assembly comprises fixed body and fixed bearing, fixed bearing is fastened on the fixed body by fix screw, the periphery of fixed bearing is installed with a plurality of calutrons, what the utility model was designed is eight calutrons, described calutron includes the coil lower cover, the coil loam cake, magnetic core, coil and magnetic pole, coil is socketed on the magnetic core, the coil loam cake is stamped in the top of coil, the below of coil is held by the coil lower cover, the top of coil loam cake is provided with magnetic pole, then by tightening screw with magnetic pole, the coil loam cake, magnetic core, the coil lower cover is fastened on the fixed bearing together; Armature comprises disk, swivel and radiating gill, swivel is fastened on the axis body, disk is a cylindrical shape, disk is fastened on the swivel by attaching screw, axis body then passes the central authorities of fixed bearing and is connected with bearing on being located at fixed body, and disk then is enclosed within the outside of each calutron, and making between the magnetic pole on disk and each calutron has an a. g., the outside of disk is provided with radiating gill, described radiating gill vertically solid matter in the periphery of disk.
During concrete work, because the rotation of axis body, also and then it rotates armature, at this moment, as long as pass through certain electric current for the calutron in the stator assembly by control capsule, the magnetic field that coil will produce, this magnetic field arrives disk by magnetic core, magnetic pole and a. g., disk just is subjected to the effect of magnetic force, the moment of torsion that has also just produced, the direction of this moment of torsion is opposite with the hand of rotation of axis body, and this reciprocal moment of torsion can play retarded acting in braking procedure; Because the polarity in every adjacent two magnetic fields that coil produced must be opposite, and disk rotates, there be N, the S utmost point of variation simultaneously in portion so within it, so just produced current vortex, current vortex can produce a large amount of dissipated heats, this dissipated heat can be dispersed in the air by the radiating gill in the disk outside, thereby has prolonged the service life of retarder.
