Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, make easily, the permanent magnet fixation, can effectively improve the traction machine permanent magnetism synchronization gear wheel free elevator traction machine rotor in useful life.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of permanent magnetism synchronization gear wheel free elevator traction machine rotor, comprise armature spindle, rotor field spider, permanent magnet, rotor field spider is installed on armature spindle, it is characterized in that: also comprise a trapezoid cross section circular ring net type permanent magnet support, circular ring net type permanent magnet support one end in trapezoid cross section embeds in rotor field spider, the other end is close on the end face that is fixed on rotor field spider, and permanent magnet is loaded on the rotor field spider inwall by trapezoid cross section circular ring net type permanent magnet support pressure.
And, described trapezoid cross section circular ring net type permanent magnet support is comprised of inner ring body, outer ring body, connector, connector is installed between inner ring body and outer ring body and makes inner ring body become as a whole with outer ring body, and inner ring body is flush-mounted in rotor field spider, and outer ring body is near being installed in the rotor field spider end face.
And, described connector and permanent magnet correspond to a plurality of, a plurality of connectors are uniform to be installed between inner ring body and outer ring body, forming cross section between two adjacent connectors is that the trapezoidal permanent magnet of arcuation clamps position, this permanent magnet clamps position and fits like a glove with the permanent magnet profile, and the external arc distance B 1 that permanent magnet clamps position is greater than the inner circle arc distance from D2.
Advantage of the present utility model and beneficial effect are:
1. this permanent magnetism synchronization gear wheel free elevator traction machine rotor, firmly suppressed permanent magnet in the rotor field spider inner ring surface by trapezoid cross section circular ring net type permanent magnet support permanent magnet difficult drop-off, rotor long service life.

Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection range of the present utility model with this.
A kind of permanent magnetism synchronization gear wheel free elevator traction machine rotor, comprise armature spindle 4, rotor field spider 1, permanent magnet 2, also comprises a trapezoid cross section circular ring net type permanent magnet support 3.Rotor field spider is installed on armature spindle, and circular ring net type permanent magnet support one end in trapezoid cross section embeds in rotor field spider, and the other end is close on the end face that is fixed on rotor field spider, and permanent magnet is loaded on the rotor field spider inwall by trapezoid cross section circular ring net type permanent magnet support pressure.
Permanent magnet is a plurality of, and this permanent magnet cross section is that arcuation is trapezoidal.Trapezoid cross section circular ring net type permanent magnet support, by inner ring body 6, outer ring body 5, connector 7, formed, connector is installed between inner ring body and outer ring body and makes inner ring body become as a whole with outer ring body, and inner ring body is flush-mounted in rotor field spider, and outer ring body is near being installed in the rotor field spider end face.Connector and permanent magnet correspond to a plurality of, a plurality of connectors are uniform to be installed between inner ring body and outer ring body, forming cross section between two adjacent connectors is that the trapezoidal permanent magnet of arcuation clamps position, this permanent magnet clamps position and fits like a glove with the permanent magnet profile, and the external arc distance B 1 that permanent magnet clamps position is greater than the inner circle arc distance from D2.
Operation principle of the present utility model is:
This permanent magnetism synchronization gear wheel free elevator traction machine rotor, by trapezoid cross section circular ring net type permanent magnet support, permanent magnet is firmly suppressed in the rotor field spider inner ring surface, the external arc distance B 1 that clamps position due to permanent magnet is greater than the inner circle arc distance from D2, and the trapezoidal position that clamps of the arcuation between the profile of permanent magnet and trapezoid cross section circular ring net type permanent magnet support connector matches fully, so permanent magnet difficult drop-off, not there will be the problem that comes off and cause rotor, traction machine to damage because of permanent magnet, but the therefore long service life of Extending Rotor and traction machine; This permanent magnetism synchronization gear wheel free elevator traction machine rotor structure is simple, makes easily, and without complicated technologies such as borings, so production and processing is easy, and production efficiency is high.
