Description
Technical field
The present invention relates to a kind of installation methods of train part, refer in particular to a kind of floated hanging side of train motor
Method, this kind of train motor suspending method can effectively improve the comprehensive performance of motor all directions, to meet various complexity
The motor hanging demand of operating condition；Belong to rail traffic manufacturing technology field.
Background technique:
The traction electric machine of train is all to be installed by way of hanging ON TRAINS mostly, motor hanging generally have axle hung type and
Bogie mounted type two ways.Wherein, motor hanging is fixed on electric machine stand, for the fixation or positioning of motor, sometimes
The connecting component of motor and lifting equipment when being also handling motor.If frame suspension type rail traction motor is exactly to be fixed by its hanging
In on train bogie, the hanging of frame suspension type rail traction motor subject motor own wt and in the process of running by
The vibration that wheel track transmits.It is higher and higher now with the speed of train, vibration frequency of high speed motor car under the conditions of high-speed cruising
It is higher, impact it is bigger, therefore bearing capacity to hanging and safety coefficient require it is higher.On general frame suspension type rail traction motor
Hanging include two with electric machine stand fixation studs, snap-gauge is fixed between stud.When installation, snap-gauge is stuck in train
Blending bolt fastens on corresponding component, to realize the outstanding positioning of the frame of motor.The snap-gauge of the motor hanging of this form is fixed on
The top of stud, stud lower part are in cantilever position, and stress is unreasonable, and bearing capacity and safety coefficient are lower, in high-speed cruising
There is situation in Shi Jiyi, and when especially encountering the operating condition of high speed motor car complexity, the bending resistance of all directions and anti-shear ability have
Higher requirement, it is easy to appear the phenomenons of fatigue for the flexible connector of motor hanging, therefore are badly in need of being improved.
