Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As Fig. 1, the utility model is made up of water cooling motor 1 and electromagnetic speed regulator 2, wherein electromagnetic speed regulator 2 is by magnetic conductor 3, yoke 4, excitation winding 5, armature 6, magnetic pole 7, tachogenerator 8 and output shaft 9 constitute, tachogenerator 8 and magnetic conductor 3 coaxial installations, excitation winding 5 is installed on the magnetic conductor 3, yoke 4 links to each other with magnetic conductor 3, the rotor 10 of tachogenerator 8 is sleeved on the output shaft 9, magnetic pole 7 is sleeved on the inner of output shaft 9, leave the gap between magnetic pole 7 and the armature 6, the outer end of output shaft 9 is used for linking to each other with the gearbox of coal-winning machine, characteristics of the present utility model are, housing 11 housings 12 direct and electromagnetic speed regulator 2 of water cooling motor 1 fuse, and the armature 6 of electromagnetic speed regulator 2 is installed on the output shaft that stretches out 13 of water cooling motor 1, cooling-water duct 14 in the water cooling motor 1 is communicated to armature 6 inboards of electromagnetic speed regulator 2 by the transition passage 15 in the two continuous housings, and be provided with delivery port 16 in electromagnetic speed regulator 2 housings 12 bottoms, correspondingly, excitation winding 5 and be equipped with seal 17 on every side between the corresponding component in the axle head of the output shaft 13 of water cooling motor 1 and electromagnetic speed regulator 2, it prevents that on the one hand cooling water from returning the inner chamber of water cooling motor 1, prevent that on the other hand cooling water from entering the excitation winding 5 in the electromagnetic speed regulator 2, also be provided with seal 18 between output shaft 9 the inners in electromagnetic speed regulator 2 and the magnetic conductor 3, prevent that cooling water from entering the work bearing of output shaft 9 and the stator 19 of tachogenerator 8.
In the utility model, output shaft 9 outer ends of electromagnetic speed regulator 2 are concordant with its housing 12 corresponding walls, and its end face has internal splined hole 20, link to each other with the coal-winning machine gearbox by the transition splined shaft, can not ring the serviceability of complete machine like this because of the rigging error face.
The position of enclosing in its output shaft 9 terminations one of correspondence of electromagnetic speed regulator 2 housings 12 is provided with seal 21, prevents that the water of workplace and moisture from entering electromagnetic speed regulator 2.
The end face diameter of the housing 11 of the utility model water cooling motor 1 should be identical with the corresponding end face diameter of electromagnetic speed regulator 2 housings 12, link to each other with the housing 11 of water cooling motor 1 by inner bolt 22 from electromagnetic speed regulator 2 housings 12 internal end surface, add seal 23 between the two housings.
