Described seal cover and end cap are fixed as one, and the relative motion on other direction of above-mentioned brake assembly and motor shaft can drop to minimum.
The utility model also goes for the transformation of existing common electric machine, and it is transformed simply, cost is low.Simultaneously, manufacturing cost of the present utility model is also low than prior art.
As preferably, brake assembly comprises that one is set in the spline housing on the described extension, the frictional disk assembly that is connected with described spline housing and transverse pressure parts that can be automatically controlled.
As preferably, transverse pressure parts that can be automatically controlled comprise armature and relative with armature elastomeric element and the stator that is arranged in the seal cover.
As preferably, be provided with the O RunddichtringO between seal cover and the end cap.
As preferably, extension is provided with and prevents that the frictional disk assembly is along the axially movable jump ring of motor shaft.
As preferably, end cap and seal cover are connected by screw, and described armature is set on the described screw.
As preferably, on the described seal cover bearing pedestal that tests the speed is installed, the described bearing pedestal that tests the speed is accepted the bearing that tests the speed, and the described bearing holder (housing, cover) that tests the speed is connected on the extension.
In sum, the utlity model has following beneficial effect:
1, the utility model has adopted brake assembly to be installed in the interior scheme of arrester of the sealing of end cap and seal cover formation, make brake assembly not be exposed under the external environment, thereby reduced the loss of brake assembly, the time of having improved the efficient of braking, having spent when having reduced maintenance and maintenance;
2, the utility model also is provided with a plurality of sealing rings and O type circle, has improved not only that the utility model is grease proofing, the waterproof and dustproof performance, has also promoted its damping performance, makes described brake assembly and motor shaft less in other direction relative motion;
3, the utility model has a cylinder shape groove in the seal cover outside, is used to install additional the bearing that tests the speed, and makes test the speed Bearing Installation, maintenance more convenient.
Description of drawings
Fig. 1 is an installation diagram of the present utility model;
Fig. 2 is that Fig. 1 is along the axial exploded view of motor shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
As shown in Figure 1, 2, have the motor of the sensing device electromagnetic brake that tests the speed, comprise motor shaft, motor case body and brake assembly, seal cover 11 can form an arrester with end cap 1; Motor shaft extends to and forms extension 4 in the arrester; Brake assembly is installed on the described extension 4.
Brake assembly comprises that one is set in the spline housing 3 on the extension 4, the frictional disk assembly 2 that is connected with spline housing 3 and transverse pressure parts that can be automatically controlled.
Transverse pressure parts that can be automatically controlled comprise armature 9 and relative with armature 9 elastomeric element 19 and the stator 10 that is arranged in the seal cover 11.
Be provided with O RunddichtringO 8 between seal cover 11 and the end cap 1.
Closed structure: fixedly connected by second screw 7 with seal cover 11 by end cap 1, stator 10 is installed in the seal cover 11, between end cap 1 and seal cover 11, carry out airtight protection by O type circle 8, seal cover 11 and the end cap 1 logical screw 20 of also crossing are fixed, the bottom of described screw 20 is provided with seal 22, thereby plays seal protection effects such as dustproof, waterproof; To the extend inwall of its seal cover 11 of traditional electromagnetic brake, dwindle armature 9 external diameters, make its inside that can be placed in seal cover 11, and certain intervals is arranged with the inwall of seal cover 11, can produce effective and reasonable electromagnetic field when making the brake assemblies energising, and braking effect is unaffected.
The sensing device structure tests the speed: in the brake assemblies upper end bearing pedestal 18 that tests the speed is installed, is used to lay the bearing 15 that tests the speed, separate with O type circle 17 and bearing pedestal 18 in the bearing bottom of testing the speed, load onto the 2nd O type circle 16 simultaneously on the bearing that tests the speed, play damping and buffering effect; Install bearing cap 14 additional in bearing pedestal upper end, in addition sealing protection is connected on the seal cover 11 by screw 12.
Operation principle: when stator 10 outage, the masterpiece that spring 19 is produced is used on the armature 9, the frictional disk assembly 2 of extension 4 driven rotary tightly is clipped between armature 9 and the end cap 1, thus the generation braking moment.At this moment, between armature 9 and stator 10, can produce a gap.When the needs take-off the brake, stator 10 is connected electricity, and the magnetic field suction armature 9 that is produced moves to stator 10, and spring 19 when armature 9 moved, and this moment, frictional disk assembly 2 was released, and braking action promptly is disengaged; Machine operation extension 4 rotates simultaneously, drives the bearing 15 that tests the speed, thereby feeds back to system by bearing 15 measured signals that test the speed, and is controlled.
