Abstract
The utility model discloses a kind of outer rotor three-phase asynchronous motor rotor locking mechanisms using steel-wire screw-socket, including outer rotor motor, the dead axle both ends of the outer rotor motor are connected with axle bed, the stator surface rotation of the outer rotor motor is socketed with rotor, and the both ends of the rotor are fixedly connected with cast aluminium end ring.This uses the outer rotor three-phase asynchronous motor rotor locking mechanism of steel-wire screw-socket by being threaded mounting hole on cast aluminium end ring and axle bed; steel-wire screw-socket is embedded in the inside of threaded mounting hole using dedicated screw tap and installation tool; form the high intensity internal thread for meeting national standard; the internal thread of enhancing and protection low-intensity cast aluminium material, improves the service life of threaded hole.
Description
Technical field
The utility model is related to motor technology field, the phase asynchronous electricity of specially a kind of outer rotor using steel-wire screw-socket
Motivation rotor locking mechanism.
Background technology
Motor is the most crucial component of treadmill, and motor performance and reliability of structure determine the quality of treadmill
And equipment life.
For inorganic shell-type outer rotor three-phase asynchronous motor, due to reducing the requirement of construction weight and volume, when design
Wish the diameter of reduction outer rotor iron core as far as possible, therefore is threaded the fixed form of mounting hole on casting aluminum rotor end ring
At option, electric motor end cap and outer rotor are connected and fixed by this threaded mounting hole.Since rotor end ring generally use is led
The casting aluminium material of good electrical property, this material hardness is small, intensity is low, in auger shell pit on cast aluminium end ring, by repeatedly repeatedly
After locking and dismounting, the threaded hole of casting aluminium material is easily damaged, stripped thread, reduces electrical machinery life, causes cost waste and system can
By the reduction of property.
For the design for boring threaded mounting hole on cast aluminium end ring, it is necessary to a kind of reliable structural measure is studied, through excessive
The precision and intensity that threaded hole is still maintained after secondary repeated disassembled and assembled, improve the service life of threaded hole.
Utility model content
The purpose of this utility model is to provide a kind of outer rotor three-phase asynchronous motor rotor locks using steel-wire screw-socket
Locking structure, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of outer rotor three using steel-wire screw-socket
The dead axle both ends of phase asynchronous motor rotor locking mechanism, including outer rotor motor, the outer rotor motor are connected with
The stator surface rotation of axle bed, the outer rotor motor is socketed with rotor, and the both ends of the rotor are fixedly connected with cast aluminium end
Ring.
Preferably, the side of the cast aluminium end ring and the upper surface of axle bed are equipped with threaded mounting hole, the screw thread installation
Hole has been internally embedded steel-wire screw-socket.
Compared with prior art, the utility model has the beneficial effects that：This is phase asynchronous using the outer rotor of steel-wire screw-socket
Motor rotor locking mechanism on cast aluminium end ring and axle bed by being threaded mounting hole, using dedicated screw tap and installation tool
Steel-wire screw-socket is embedded in the inside of threaded mounting hole, forms the high intensity internal thread for meeting national standard, enhance and is protected is low strong
The internal thread for spending cast aluminium material, improves the service life of threaded hole.

Limitation.
- 5 are please referred to Fig.1, the utility model provides a kind of technical solution：It is a kind of different using the outer rotor three of steel-wire screw-socket
Motor rotor locking mechanism is walked, including outer rotor motor 6, the dead axle both ends of outer rotor motor 6 are connected with axle bed 5,
The stator surface rotation of outer rotor motor 6 is socketed with rotor 1, and the both ends of rotor 1 are fixedly connected with cast aluminium end ring 2, cast aluminium end
The side of ring 2 and the upper surface of axle bed 5 are equipped with threaded mounting hole 3, and threaded mounting hole 3 has been internally embedded steel-wire screw-socket 4.
The utility model is in the specific implementation：It is threaded mounting hole 3 on cast aluminium end ring 2 and axle bed 5, using dedicated silk
Steel-wire screw-socket 4 is embedded in the inside of threaded mounting hole 3 by cone and installation tool, forms the high intensity internal thread for meeting national standard,
The internal thread of enhancing and protection low-intensity cast aluminium material, improves the service life of threaded hole.
