Abstract
The utility model relates to a motor commutator, in particular to a motor commutator used for motors. The motor commutator comprises a shell composed of a transparent cover and a transparent cover seat, a longitudinal cuboid output shaft vertically arranged on the shell and a horizontal rectangular input shaft. The input shaft and the output shaft are respectively connected with bevel gears which are meshed with each other, and after each bevel gear is additionally provided with a large flat mat, the bevel gears are respectively fixed on the input shaft and the output shaft through fixing bolts. Sleeves are arranged at the combination portions of the transparent cover and the output shaft and the combination portion of the transparent cover and the input shaft, a bearing is arranged in each sleeve, a sleeve mat is additionally arranged on each bearing, and then nut end sockets are used for sealing. The motor commutator has the advantages that the structure is simple, using is convenient, centrifugal force generated when a motor revolves is used as power, magnitude of starting resistance is controlled, and therefore starting currents of the motor are reduced, starting torque is increased, and brushless automatic control operation of a wound-rotor type asynchronous electric motor is achieved.
Description
Technical field
The utility model relates to the used engine commutator of a kind of motor.
Background technique
In the working principle of motor, rotor rotates, and can not import rotor coil to power supply with fixing line, so, the power supply electric energy is imported in the rotor coil through the sliding contact of carbon brush and slip ring.If the current direction in the rotor coil is constant all the time, rotor will be parked in the pole pair position that there is a natural attraction between the sexes draws of pole pair and the stator of rotor coil, no longer rotate, so, must be when rotor forwards several angle to, change its current direction, just change the pole orientation of rotor coil, make rotor can under the stator magnetic force, continue to rotate forward.If there is not the effect of engine commutator, it is just stuck less than half-turn that motor can only change, and can only be used as electric brake.The centrifugal force that produces when utilizing the motor rotation is as power, and the size of control starting resistance reaches and reduces electric motor starting electric current, increase starting torque, makes Wound-rotor asynchronous electric thought realize the device of brushless automatic control operation.
Summary of the invention
The purpose of this utility model provides a kind of engine commutator, realizes the commutation of motor in limited space to greatest extent.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of engine commutator, comprise the housing that lid and saturating cage are formed, it is characterized in that: also comprise the output shaft of rectangular longitudinally that has on the housing and horizontal rectangular input shaft, described input shaft is connected intermeshing umbrella gear respectively with output shaft, after adding big flat washer on each umbrella gear, be separately fixed on input shaft and the output shaft by fixing bolt; Described lid and output shaft and input shaft connecting part are provided with cover, are provided with bearing in the cover, add a sleeve gasket at each bearing, then by the sealing of nut end socket.
Above-described cage is provided with a through hole, and through hole is provided with plug.
The utility model beneficial effect is, and is simple in structure, easy to use, the centrifugal force that produces when utilizing the motor rotation is as power, the size of control starting resistance reaches and reduces electric motor starting electric current, increase starting torque, makes Wound-rotor asynchronous electric thought realize the brushless automatic control operation.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1. output shaft; 2. nut end socket; 3. bearing; 4. cover thoroughly; 5. umbrella gear; 6. big flat washer; 7. plug; 8. fixing bolt; 9. saturating cage; 10. sleeve gasket; 11. cover; 12. hexagon head screw rod; 13. input shaft.
Embodiment
By accompanying drawing 1 as can be known, the utility model is by rectangular output shaft 1 and horizontal rectangular input shaft 13 are formed by connecting for basic framework longitudinally.The end of output shaft 1 and input shaft 13 is connected umbrella gear 5 respectively, and it is fixing by fixing bolt 8, umbrella gear 5 after fixing is arranged in the housing of being made up of the saturating lid 4 of T font and saturating cage 9, saturating lid 4 and saturating cage 9 are fastenedly connected by hexagon head screw rod 12, be provided with big flat washer 9 between umbrella gear 5 in engine commutator and the fixing bolt 8, each umbrella gear has the key (not shown) that is provided with two rectangles for about 5 li, make the umbrella gear 5 after the connection more fastening, can not cause gear to slide and influence using effect.
In position, the left side, medial axis, the utility model engine commutator outside a through hole is arranged, through hole is provided with plug 7.The right side then is the input shaft of giving prominence to 13 on the engine commutator medial axis.
Should be noted that mode of execution described in the utility model only is its optimal way, only is apparent change to belonging to technical solutions of the utility model, all should belong within the protection domain of the present utility model.
Claims (2)
