It is more complicated, add the volume of ball screw insertion motor and the complexity of structure.
The content of the invention
The purpose of this utility model is to provide a kind of insertion motor simple in construction based on ball screw.
The technical scheme for solving above-mentioned technical problem is as follows：
Insertion motor based on ball screw, including stator, rotor, bearing, end cap, armature spindle, ball screw, rotor position
In in stator, the both ends of stator are fixedly connected with end cap respectively, and the bearing is fixed in end cap, after armature spindle passes through rotor,
The both ends of armature spindle are fixed with bearing respectively, and armature spindle is fastened with rotor circumferentially, it is characterised in that：Also include ball spiral shell
Female, compacting part, the ball nut are located in armature spindle endoporus and fastened with armature spindle circumferentially, the armature spindle
It is fixed in endoporus at least provided with first step, one end of the ball nut by first step axial limiting, compacting part
In the endoporus of armature spindle, the other end axial limiting of ball nut is in compacting part, ball screw insertion armature spindle and and ball
Nut cooperatively forms screw body.
Further, screw thread is provided with the endoporus of the armature spindle, the periphery of the compacting part is provided with external screw thread,
Compacting part passes through screw thread and rotor axis connection.
Further, in addition to key, the ball nut carry out circumferential fastening by key and armature spindle.
The advantages of the utility model：Ball nut has been arranged on to the inside of armature spindle, has reduced the volume of armature spindle, and
The transmission of ball nut is no longer rely on ring flange, and the structure of ball nut and armature spindle is simplified, therefore, this reality
Not only it is simplified in structure with new, and is also reduced in volume side's product, for the cost of motor
Reduced.
