Description
Technical field
Mechanical manufacturing field is the utility model is related to, more particularly to a kind of electromagnetic brake.
Background technology
With the development and development of Machine Manufacturing Technology, as the brake of an important machine components in machinery, meet
The opportunity to develop that another wheel continues health is carried out.
At present, electromagnetic brake can be divided into single-disk brake and multiple-disc brake.In single-disk brake, motor shaft and flower
Key boss connects, and in braking, multiple spline hub drives the rotor of rotation to be clamped tightly between armature and flange, so as to produce system
Kinetic moment is pinned motor shaft and can not rotated.But due to having a small―gap suture between the rotor and multiple spline hub of brake, with
And there is also fit clearance between armature and positioning sleeve, therefore, motor shaft is not pinned completely, causes to turn round.
Therefore, exist in the prior art and gap and armature and positioning sleeve between the rotor of brake and multiple spline hub be present
Between there is also fit clearance, the technological deficiency for causing motor shaft to turn round can not be agreed with completely.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of electromagnetic brake, it is existing to solve
Have present in technology due to gap be present between the rotor and multiple spline hub of brake, electricity when causing braking can not be agreed with completely
The technological deficiency of arbor revolution.
To achieve these goals, the utility model uses following technical scheme：
A kind of electromagnetic brake, including motor housing, motor shaft, rotor, brake positioning sleeve, brake stator, braking
Device spring, brake armature；The rotor is fixedly connected on the motor shaft, the brake stator and brake rank
Iron is connected with the motor housing, and spring leaf is connected between the brake stator and the brake armature.
Preferably, the rotor, which is fixedly connected on the motor shaft, is specially：The rotor is fixed by the first screw
It is connected on the motor shaft.
Preferably, the brake stator and the brake armature are connected with the motor housing and are specially：The system
Dynamic device stator and the brake armature are connected by the second screw with the motor housing.
Preferably, the positioning sleeve for being positioned for second screw is provided with the motor housing.
Preferably, the spring leaf is connected with the brake stator and the brake armature respectively by lock-screw
Connect.
Compared with prior art, the utility model has following technology a little：
Due to electromagnetic brake provided by the utility model, traditional multiple spline hub is eliminated, rotor is fixedly attached to
On motor shaft, avoid due to gap between rotor and multiple spline hub be present, motor shaft when causing braking can not be agreed with completely and returned
The technological deficiency turned；Further, due to electromagnetic brake provided by the utility model, in brake stator and brake armature
Between employ spring leaf connection, solve the gap of armature left rotation and right rotation realize completely pin motor shaft technique effect.
Brief description of the drawings
Fig. 1 is the structural representation of electromagnetic brake provided by the utility model；
Fig. 2 is the Section A-A sectional view of electromagnetic brake provided by the utility model.
Embodiment
The utility model embodiment provides a kind of electromagnetic brake, to solve present in prior art due to braking
Gap be present between the rotor and multiple spline hub of device, the technological deficiency of motor shaft revolution when causing braking can not be agreed with completely.
To make the purpose of this utility model, technical scheme and advantage clearer, implement below in conjunction with the utility model
Accompanying drawing in example, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that described reality
It is the utility model part of the embodiment to apply example, rather than whole embodiments.Based on the embodiment in the utility model, ability
The every other embodiment that domain those of ordinary skill is obtained under the premise of creative work is not made, it is new to belong to this practicality
The scope of type protection.
The utility model embodiment provides a kind of electromagnetic brake, refer to Fig. 1 and Fig. 2, the electromagnetic brake bag
Include motor housing 1, motor shaft 2, rotor 3, brake stator 4, brake spring 5, brake armature 6；Rotor 3 is fixedly connected on
On motor shaft 2, brake stator 4 and brake armature 6 are connected with motor housing 1, brake stator 4 and brake armature 6 it
Between be connected with spring leaf 10.
As preferable, rotor 3 is fixedly connected on the motor shaft by the first screw 7.
As preferable, brake stator 4 and brake armature 6 are connected by the second screw 8 with motor housing 1.
As preferable, the positioning sleeve 9 for being positioned for second screw is provided with motor housing 1.
As preferable, spring leaf 10 is connected with brake stator 4 and brake armature 6 respectively by lock-screw 11.
The braking procedure of the electromagnetic brake is：
After brake stator 4 powers off, power caused by brake spring 5 is acted on brake armature 6, brake armature
6 end face and the end contact of rotor, produce frictional force and pin motor shaft so as to produce braking moment, prevent motor shaft from revolving
Turn.Now, occurs a gap S between brake armature 6 and brake stator 4；When needing to loosen braking, brake stator
4 switch on power, and produce a magnetic field, and magnetic field suction brake armature 6 moves to brake stator 4, when brake armature 6 moves
Compression brake spring 5, now, rotor 3 depart from brake armature 6, brake contact, and motor shaft 2 enters normal rotation.
Compared with prior art, the utility model has following technological merit：
Due to electromagnetic brake provided by the utility model, traditional multiple spline hub is eliminated, rotor is fixedly attached to
On motor shaft, avoid due to gap between rotor and multiple spline hub be present, motor shaft when causing braking can not be agreed with completely and returned
The technological deficiency turned；Further, due to electromagnetic brake provided by the utility model, in brake stator and brake armature
Between employ spring leaf connection, eliminate the gap of armature left rotation and right rotation, realize the technique effect for pinning motor shaft completely.
It should be understood by those skilled in the art that, the foregoing is only preferred embodiment of the present utility model, not it is used for
Limit the scope that the utility model is implemented, all shape, construction, feature and spirit according to described in the utility model claims scope
Carried out by equivalent changes and modifications, right of the present utility model all should be included in.
