Description
Technical field
The invention belongs to dynamo-electric machine rotor iron core dress pressure technical field, the rotor iron core being specifically related to a kind of transmitting torque connects with rotating shaft uses Macintosh.
Background technique
Under normal circumstances, the installation process of dynamo-electric machine rotor iron core is: after dynamo-electric machine rotor iron core is soldered sliver and copper end ring, by hot jacket in rotating shaft, then parallel key is squeezed into, because keyway in keyway in rotor core and rotating shaft usually can not centering very well in hot jacket process, parallel key can not match with both keyways after squeezing into by force, therefore for clockwise and anticlockwise and after transmitting larger moment of torsion frequently in high capacity motor rotation process, easily cause transmitting torque effect bad, even there is short distance phenomenon of " climbing axle ", greatly reduce the working life of rotor iron core and rotating shaft, also have some installation methods be hot jacket in rotating shaft after, carry out spot welding, this type of installation method is unfavorable for later replacing or dismounting, and its one being exactly directly countershaft and rotor iron core is destroyed.
In order to better avoid and eliminate the generation of this type of side effect, can effective transmitting torque, reasonable installation, needs to improve its mounting structure.
Summary of the invention
The object of the invention is for above-mentioned Problems existing and deficiency, even if when providing a kind of rotor iron core keyway and rotating shaft keyway not to the heart, the rotor iron core that still can carry out reliable delivery moment of torsion connects with rotating shaft uses Macintosh.
For achieving the above object, the technological scheme taked is:
A kind of rotor iron core connects with Macintosh with rotating shaft, comprise the main Macintosh and time Macintosh that are fixedly installed on transmitting torque in rotor iron core keyway and rotating shaft keyway, one end of described main Macintosh and rotor iron core keyway match be adjacent to fixing, the other end of main Macintosh is provided with inclined groove relative to the dual-side of rotating shaft keyway, described secondary Macintosh is provided with the obliquity prominence platform mated with inclined groove, and secondary Macintosh wedging is fixed between main Macintosh and rotating shaft keyway.
The gradient of described inclined groove and the plane of inclination of obliquity prominence platform is 1:(150 ~ 250).
Main Macintosh to be divided into the identical left main Macintosh of two structures and right main Macintosh by the inclined-plane of an axial direction by described main Macintosh, and left main Macintosh and right main Macintosh are by inclined-plane transmitting torque bonded to each other.
The gradient on described inclined-plane is 1:(150 ~ 250).
The true dip direction of the inclined groove of described main Macintosh both sides is identical.
Described rotating shaft width of keyway is wide compared with rotor iron core width of keyway.
Adopt technique scheme, acquired beneficial effect is:
The present invention is by carrying out improvement and the design of structure by the connecting key of rotor iron core and rotating shaft, make to have the following advantages: 1. solve rotor iron core keyway and rotating shaft keyway hot jacket install after not bad to transmitting torque effect when heart situation, by the change of the mounting type of Macintosh, avoid by force after load key key and keyway misfit; 2. adopt Macintosh of the present invention easy for installation, a mounting technique difficult problem can not be brought because of the change of the structure of Macintosh, and convenient later maintenance; 3. transmitting torque is effective, and the present invention, by inclined-plane transmitting torque, has certain requirement to the gradient on inclined-plane, and it is not only applicable to the characteristic of installing, and simultaneously in motor forward/backward rotation process, is also the secondary pretension effect produced Macintosh; 4. adopt in installation process of the present invention and can not cause damage to rotor iron core and rotating shaft, greatly can also improve overall working life simultaneously, improve the stability of rotor iron core and rotating shaft.
