Greatly, fever is serious, influences motor service life.How to prevent the generation of such event cannot be singly under operator's technical level
It is very necessary to research and develop a kind of better motor for hand.
Utility model content
First technical problem to be solved in the utility model is: provide it is a kind of facilitate installation transmission parts, be driven
When component is installed, the Split-type rotor axis of rotor shaft distortion will not be caused.
Second technical problem to be solved in the utility model is: a kind of motor is provided, using above-mentioned armature spindle.
In order to solve above-mentioned first technical problem, the technical solution adopted in the utility model is:
A kind of Split-type rotor axis, including rotor shaft body and output shaft；
The rotor shaft body is rectangular section close to the end of the output shaft, and the output shaft is close to the armature spindle sheet
The end of body axially offers square groove, and the size of the square groove is adapted with rectangular section of the size；
The middle part of the output shaft axially offers tapped through hole, and rectangular section of the middle part axially offers and the spiral shell
The consistent threaded hole of the thread parameter of line through-hole；
In the rectangular section of insertion square groove, the tapped through hole and the threaded hole are threaded with a spiral shell
Bolt.
Preferably, the tapped through hole on the output shaft is counterbore.
Preferably, the output shaft includes leading portion and back segment, and the diameter of the back segment is greater than the diameter of the leading portion, described
Square groove is set to the back segment.
In order to solve above-mentioned second technical problem, the technical solution adopted in the utility model is:
A kind of motor, including armature spindle, the armature spindle are above-mentioned Split-type rotor axis.
By adopting the above-described technical solution, the beneficial effects of the utility model are:
The Split-type rotor axis of the utility model first installs transmission parts, then using separate structure on output shaft
By in the square groove of rectangular section of insertion output shaft back segment of rotor shaft body, then the screw thread that a bolt is screwed into output shaft is led to
Hole, bolt pass through output shaft, until being screwed into the threaded hole of rotor shaft body, are detachably connected output shaft and rotor shaft body.
The armature spindle of such structure, rotor shaft body and output shaft are divided into separate structure, when install transmission parts, output shaft with turn
Sub- shaft body separation will not make armature spindle body distortion, the concentricity of rotor shaft body when output shaft is struck by external force
It is good, ensure the good operation of motor.
