Abstract
Lean on dry -type monolithic electromagnetic braking ware of involute spline carry -over moment relates to electromagnetic braking ware technical field, by transmission shaft, yoke, armature, bearing, gradually burst at the seams external splines cover and armature inner circle, the fixed suit of the external splines that gradually bursts at the seams cover on the transmission shaft, at gradually the burst at the seams outside suit and the bearing of external splines cover, the bearing outside sets gradually installs yoke, armature and spring leaf, the installation is provided with the armature inner circle between armature and the external splines that gradually the bursts at the seams cover. The utility model discloses structural design is novel reasonable, and the moment spaced point is more, can effectively improve the security and the stability of dry -type monolithic electromagnetic braking ware, is favorable to improving braking effect and life.
Description
Technical field:
The utility model relates to electromagnetic brake technical field, is specifically related to the dry single-disk electromagnetic brake by involute spline carry-over moment.
Background technology:
Electromagnetic brake is a kind of connector that master end torsion is conveyed to passive side, can, according to needs combination freely, cut off or brake, and because carrying out start by electromagnetic force, is referred to as electromagnetic clutch, and brake, has fast response time, advantages of simple structure and simple. The various ways such as electromagnetic brake can be divided into electromagnetic power brake and electromagnetic whirlpool brake, electromagnet-friction formula brake. Also be subdivided in addition dry single-disk electromagnetic brake, dry-type multidisc electromagnetic brake, Wet-type multi-disc electromagnetic brake etc. Can be divided into again energising braking and power-off brake by mode of braking electromagnetic brake.
But common dry single-disk electromagnetic brake is all to adopt rivet to connect and carry-over moment, this mode torque ratio disperses, easily occur that rivet fracture causes the situation of brake troubles, this patent discloses a kind of dry single-disk electromagnetic brake that utilizes involute spline carry-over moment and can effectively prevent the above-described problem from occurring, and has ensured braking effect and life-span.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of structural design new reasonable, moment spaced point is more, can effectively improve the safety and stability of dry single-disk electromagnetic brake, be conducive to improve the dry single-disk electromagnetic brake by involute spline carry-over moment in braking effect and service life.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
By the dry single-disk electromagnetic brake of involute spline carry-over moment, by power transmission shaft, yoke, armature, bearing, involute outer spline cover and armature inner ring, described involute outer spline cover is fixedly set on power transmission shaft, at the outside of involute outer spline cover suit and bearing, described bearing outside sets gradually yoke is installed, armature and spring leaf, between described armature and involute outer spline cover, install and be provided with armature inner ring, described armature inner ring is involute inner spline, described armature inner ring and involute outer spline cover can be intermeshing, described spring leaf is mounted on the outside of armature, and be connected with involute outer spline cover with armature inner ring,
When common dry single-disk electromagnetic brake energising work, produce magnetic field, armature is inhaled to yoke, electromagnetic force reaches two rivets successively by armature, finally reach and connect power transmission shaft locking, in the time that power supply disconnects, magnetic field disappears, and armature resets under the reaction force of spring leaf, and power transmission shaft can rotate freely;
And when the utility model brake energising work, produce magnetic field, and armature is inhaled to yoke, and electromagnetic force reaches involute outer spline cover by power transmission shaft locking by armature inner ring involute spline; In the time that power supply disconnects, magnetic field disappears, and armature resets under the reaction force of spring leaf, and power transmission shaft can rotate freely;
Hence one can see that, and common dry single-disk electromagnetic brake is by rivet carry-over moment, moment is dispersed on 3 rivets, the utility model single-disk brake is by involute spline carry-over moment, moment is dispersed in more than on 20 involute splines, in the time of the long-term frequent operation of brake, the former rivet is easy to be cut off by spring leaf because of stressed concentrating, and the latter there will not be analogue;
The beneficial effects of the utility model are: structural design is new reasonable, and moment spaced point is more, can effectively improve the safety and stability of dry single-disk electromagnetic brake, are conducive to improve braking effect and service life.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Wherein: 1-power transmission shaft; 2-yoke; 3-armature; 4-bearing; 5-involute outer spline cover; 6-armature inner ring; 7-spring leaf.
Detailed description of the invention:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, by the dry single-disk electromagnetic brake of involute spline carry-over moment, by power transmission shaft 1, yoke 2, armature 3, bearing 4, involute outer spline cover 5 and armature inner ring 6, described involute outer spline cover 5 is fixedly set on power transmission shaft 1, at the outside of involute outer spline cover 5 suit and bearing 4, described bearing 4 outsides set gradually yoke 2 are installed, armature 3 and spring leaf 7, between described armature 3 and involute outer spline cover 5, install and be provided with armature inner ring 6, described armature inner ring 6 is involute inner spline, described armature inner ring 6 can be intermeshing with involute outer spline cover 5, described spring leaf 7 is mounted on the outside of armature 3, and be connected with involute outer spline cover 5 with armature inner ring 6,
When common dry single-disk electromagnetic brake energising work, produce magnetic field, armature is inhaled to yoke, electromagnetic force reaches two rivets successively by armature, finally reach and connect power transmission shaft locking, in the time that power supply disconnects, magnetic field disappears, and armature resets under the reaction force of spring leaf, and power transmission shaft can rotate freely;
And when the utility model brake energising work, produce magnetic field, and armature is inhaled to yoke 2, and electromagnetic force reaches involute outer spline by armature inner ring 6 involute splines and overlaps 5 by power transmission shaft 1 locking; In the time that power supply disconnects, magnetic field disappears, and armature 3 resets under the reaction force of spring leaf 7, and power transmission shaft 1 can rotate freely;
Hence one can see that, and common dry single-disk electromagnetic brake is by rivet carry-over moment, moment is dispersed on 3 rivets, the utility model single-disk brake is by involute spline carry-over moment, moment is dispersed in more than on 20 involute splines, in the time of the long-term frequent operation of brake, the former rivet is easy to be cut off by spring leaf because of stressed concentrating, and the latter there will not be analogue;
More than show and described general principle of the present utility model and principal character and advantage of the present utility model. The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
