Abstract
The utility model relates to a motor, and specially relates to an axially anti-drifting structure for a motor rotor. The axially anti-drifting structure comprises a motor housing, a stator, a rotor coil and a rotor shaft. The axially anti-drifting structure is characterized in that the rotor shaft is provided with a bearing at the position connected with the motor housing, one side of the bearing is embedded in the motor housing, the other side of the bearing is provided with a bearing fixing plate, and the bearing fixing plate matches the motor housing by bolt joint. The rotor shaft is provided with a limiting groove at the inner side of the bearing, and the rotor shaft is provided with a shaft back-up ring outside the bearing. According to the axially anti-drifting structure, the connection position of the rotor shaft and the motor housing is provided with the limiting groove and the shaft back-up ring, drifting is prevented when the rotor shaft runs, the load capability of the motor is enhanced, and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to a kind of motor, is specially a kind of axial anti-channeling structure of rotor.
Background technology
Motor, using an end after the time, just there will be the problem of the upper and lower play of armature spindle, can affect like this useful life of carrying load ability and the motor of motor, therefore designs a kind ofly can prevent that the structure of armature spindle play is just very necessary.
The utility model content
For the problem existed in existing technique, the purpose of this utility model is to provide a kind of technical scheme of axial anti-channeling structure of rotor.
The axial anti-channeling structure of described a kind of rotor, comprise electric machine casing, stator, rotor coil and armature spindle, it is characterized in that described armature spindle and electric machine casing junction are provided with bearing, bearing one side interlocking is in electric machine casing, the bearing opposite side arranges bearing (setting) plate, bearing (setting) plate and electric machine casing threaded; On the described armature spindle that is positioned at the bearing inboard, stopper slot is set, is positioned on the armature spindle in the bearing outside shaft block ring is set.
The axial anti-channeling structure of described a kind of rotor, is characterized in that arranged outside oil sealing, oil sealing and the armature spindle interference fit of described shaft block ring.
The utility model arranges stopper slot and shaft block ring at armature spindle and electric machine casing junction, can effectively prevent the problem of play when armature spindle moves, and has increased the carrying load ability of motor, has also extended the useful life of motor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-electric machine casing, 2-stator, 3-rotor coil, 4-armature spindle, 5-bearing, 6-bearing (setting) plate, 7-shaft block ring, 8-stopper slot, 9-oil sealing.
Embodiment
Below in conjunction with Figure of description, the utility model is described further:
A kind of axial anti-channeling structure of rotor, comprise electric machine casing 1, stator 2, rotor coil 3 and armature spindle 4, and above-mentioned member connection structure is prior art, does not repeat them here.Be provided with bearing 5 in armature spindle 4 and electric machine casing 1 junction, bearing 5 one side interlockings are in electric machine casing 1, and bearing 5 opposite sides arrange bearing (setting) plate 6, and bearing (setting) plate 6 and electric machine casing threaded, for rigid bearing; Be positioned on the armature spindle 4 of bearing 5 inboards stopper slot 8 is set, be positioned on the armature spindle 4 in bearing 5 outsides and shaft block ring 7 be set, the arranged outside oil sealing 9 of shaft block ring 7, oil sealing 9 and armature spindle 4 interference fit; Cooperation by stopper slot 8 and shaft block ring 7 can guarantee that play does not occur while moving armature spindle 4.
The utility model arranges stopper slot and shaft block ring at armature spindle and electric machine casing junction, can effectively prevent the problem of play when armature spindle moves, and has increased the carrying load ability of motor, has also extended the useful life of motor.
