The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of structure simple, the solid rotor box hat brake motor of good braking effect.
The utility model solves the technical scheme that its technical problem adopts: a kind of solid rotor box hat brake motor, comprise box hat, box hat front end is provided with front end housing, box hat rear end is provided with rear end cap, box hat center is provided with rotating shaft, front end housing and rear end cap are stretched out in rotating shaft two ends, front end housing are provided with the oil sealing that countershaft seals; Described box hat inwall is installed with stator, is arranged with the rotor corresponding with stator outside rotating shaft;
Described rear end cap is provided with fan housing, fan housing is built-in with brake disc, magnetic grips assembly and fan blade, brake disc empty set is located in rotating shaft, is provided with the sheathed geared sleeve be arranged in rotating shaft, there is space between brake disc and geared sleeve between brake disc and rotating shaft; Magnetic is gripped assembly and is fixedly mounted on rear end cap, and magnetic is gripped assembly and is connected with armature by spring, and armature is fixedly connected with brake disc, and fan blade is sheathed to be fixed in rotating shaft.Rotor is solid construction.
Further, described front end housing is fixedly connected with box hat by front bolt, box hat, is fixedly connected with by rear bolt between rear end cap and fan housing three, and magnetic is gripped assembly and is fixedly mounted on rear end cap by hollow bolt,
Further, described box hat outer wall is provided with terminal box, and terminal box is built-in with the control integration block gripped electrical component with stator and magnetic and be connected.
Further, described front end housing and rear end cap are all provided with the bearing of supporting revolving shaft.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to operate, have that volume is little, lightweight, good braking effect, starting current are little, be suitable for frequent starting, operate steadily reliable; Large, the startability of torque and overload capacity strong feature when having a startup, even if motor stall also can not burn out motor in 4-5 minute; Shaftless play, stable working during the work of this motor, decrease impact to drive disk assemblies such as gears, extend crane service life, the object sling is heavier, and Soft Starting Performance better.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. rotating shafts, 2. oil sealing in figure, bolt 3., 4. front end housing, 5. bearing, 6. stator, 7. rotor, 8. control integration block, 9. box hat, 10. rear end cap, bolt after 11., 12. brake discs, 13. geared sleeves, 14. armature, 15. hollow bolts, 16. magnetic grip assembly, 17. fan blades, 18. fan housings.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Solid rotor box hat brake motor as shown in Figure 1, comprises box hat 9, and box hat 9 front end is provided with front end housing 4, box hat 9 rear end is provided with rear end cap 10, box hat 9 center is provided with rotating shaft 1, and front end housing 4 and rear end cap 10 are stretched out in rotating shaft 1 two ends, front end housing 4 is provided with the oil sealing 2 that countershaft 1 seals; Box hat 9 inwall is installed with stator 6, is arranged with the rotor 7 corresponding with stator 6 outside rotating shaft 1;
Rear end cap 10 is provided with fan housing 18, fan housing 18 is built-in with brake disc 12, magnetic grips assembly 16 and fan blade 17, brake disc 12 empty set is located in rotating shaft 1, is provided with the sheathed geared sleeve 13 be arranged in rotating shaft 1, there is space between brake disc 12 and geared sleeve 13 between brake disc 12 and rotating shaft 1; Magnetic is gripped assembly 16 and is fixedly mounted on rear end cap 10, and magnetic is gripped assembly 16 and is connected with armature 14 by spring, and armature 14 is fixedly connected with brake disc 12, and fan blade 17 is sheathed to be fixed in rotating shaft 1.
Front end housing 4 is fixedly connected with box hat 9 by front bolt 3, box hat 9, is fixedly connected with by rear bolt 11 between rear end cap 10 and fan housing 18 three, and magnetic is gripped assembly 16 and is fixedly mounted on rear end cap 10 by hollow bolt 15; Box hat 9 outer wall is provided with terminal box, and terminal box is built-in with the control integration block 8 gripped assembly 16 with stator 6 and magnetic and be electrically connected; Front end housing 4 and rear end cap 10 are all provided with the bearing 5 of supporting revolving shaft 1.
