Description
Technical field
The present invention relates to a kind of motor benches, and in particular to a kind of test Split type electric machine frame belongs to Split type electric
The technical field of performance test of machine.
Background technique
Either pure electric mode or hybrid power mode, motor are more important in automobile industry role.It carries out
The bench test of motor product, to motor performance is understood, exploitation automobile power all has positive effect.Motor can be divided into integral type
Motor and split type motor can be completed installation rack by fixing motor housing body, have benefited from the support of mounting plate for the former,
It is smoothly operated as long as spline fitted is proper.But for the latter, then need that first rotor is connected in drive shaft, then will determine
Son is fixed on rack, this means that the driving structure of motor will not only drive rotor to operate, and also to undertake the weight of rotor,
But in view of needing certain safety clearance between rotor and stator, just it is avoided that both generations are touched when rotating at high speed
It hits, damages motor, this is clearly unreasonable.
In addition, the mounting hole of different type motor has differences, if the L-type mounting bracket of replacement test-bed, either
Cost or workload are not a kind of selections of wisdom.
Summary of the invention
The object of the present invention is to provide a kind of test Split type electric machine frames, to solve conventional two-piece motor bench
Output end needs to undertake the weight of rotor, is easy to happen rotor and stator collision accident, and can only measure single model motor
Problem.
A kind of test Split type electric machine frame includes stator casing, rotor, mounting plate, L-type support, drive shaft
System, rack input shaft and rack drive dynamometer machine；
L-type support and rack driving dynamometer machine are fixedly mounted on rack, and stator casing is fixedly mounted on L by mounting plate
On type bracket, driving shafting is mounted in L-type support, drives one end of shafting and the rotor phase that is mounted in stator casing
Connection drives the other end of shafting to drive the rack input shaft on dynamometer machine to be connected with rack.
Preferred: driving shafting includes first flange, shell, bearing, drive shaft, spline and second flange；
Shell is fixedly mounted in L-type support by second flange, one end of drive shaft pass through shell and second flange with
First flange is connected, and drive shaft is rotatablely connected by bearing and shell and second flange, and the other end of drive shaft passes through flower
Key is connected with rack input shaft.
Preferred: rotor is connected by first flange with drive shaft.
The present invention has the effect that compared with existing product
1, by L-type support and the weight for driving shafting that rack driving structure can be avoided to undertake rotor, and as far as possible
Guarantee that concentricity is in the range of rotor trouble free service；2 in view of there are certain differences for different types of motor installing hole
It is different, except rack L-type mounting bracket, then the design by installing mounting plate additional, the electricity of different model can be replaced with Fast Installation
Machine reduces the cost and workload of installation.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of test Split type electric machine frame；
Fig. 2 is the structural schematic diagram for driving shafting.
In figure: 1- stator casing, 2- rotor, 3- mounting plate, 4-L type bracket, 5- driving shafting, the input of 6- rack
Axis, 7- rack drive dynamometer machine, 8- first flange, 9- shell, 10- bearing, 11- drive shaft, 12- spline, 13- second flange.
Specific embodiment
The preferred embodiment of the present invention is elaborated below according to attached drawing.
As depicted in figs. 1 and 2, a kind of test Split type electric machine frame of the present invention includes stator casing 1, motor
Rotor 2, mounting plate 3, L-type support 4, driving shafting 5, rack input shaft 6 and rack drive dynamometer machine 7；
L-type support 4 and rack driving dynamometer machine 7 are fixedly mounted on rack, and stator casing 1 passes through the fixed peace of mounting plate 3
In L-type support 4, driving shafting 5 is mounted in L-type support 4, is driven one end of shafting 5 and is mounted in stator casing 1
Rotor 2 is connected, and the other end of shafting 5 is driven to be connected with the rack input shaft 6 on rack driving dynamometer machine 7.
Further, driving shafting 5 includes first flange 8, shell 9, bearing 10, drive shaft 11, spline 12 and second flange
13；
Shell 9 is fixedly mounted in L-type support 4 by second flange 13, and one end of drive shaft 11 passes through shell 9 and second
Flange 13 is connected with first flange 8, and drive shaft 11 is rotatablely connected by bearing 10 and shell 9 and second flange 13, driving
The other end of axis 11 is connected by spline 12 with rack input shaft 6.
Further, rotor 2 is connected by first flange 8 with drive shaft 11.
It is connected by bolt with the rotor of split type motor, the other end is the input axis connection of spline and rack, this is just real
The transmission agency of the set shafting is showed.Outermost is the shell of protection and support, among size shape and L-type mounting bracket
Pore size is consistent, in the guaranteed design with L-type support relative position in the side of shell.It is axis between shell and drive shaft
It holds.When, driving rack driving working rotor, the drive shaft high speed rotation in shafting passes through the design of bearing, it is ensured that shell
Keep opposing stationary with L-type mounting bracket.The quality of rotor is transmitted on rack by drive shaft, bearing and shell, more
It is firm.About bearing, at least two in quantity.On the one hand such design is more firm, on the other hand, is more advantageous to guarantee quilt
Survey the concentricity between part, driving shafting and rack.
Except L-type mounting bracket, an individual mounting plate is redesigned, is through-hole among this mounting plate, can stretch out
Drive shafting.There is two parts mounting hole above, a part of mounting hole is used to mounting plate being fixed to L-type mounting bracket, another
Part, for fixing the stator of motor.In this way, when replacing the motor of different model every time, it is only necessary to corresponding mounting plate is replaced,
It is time saving and energy saving.
Shafting 5 is driven to pass through the through-hole at 4 center of L-type mounting bracket from right to left, by bolt by the flange 13 on shell
It is connected to L-type mounting bracket, this completes the fixations of shafting shell；The mounting plate 3 of motor is bolted L-type peace
It fills on bracket 4；The rotor of split type motor on the flange 8 fixed to driving shafting 5, completes the connection of the two by bolt,
Drive shafting that will drive rotor rotation by flange 8 when test；The stator casing 1 of split type motor is fixed on mounting plate 3,
This completes the states that stator is remain stationary in test relative to rotor；The input shaft that rack drives dynamometer machine 7 to stretch out
6, it is connected together with the drive shaft 11 of driving shafting 5 by interior external splines.
This embodiment is just an exemplary description of this patent, does not limit its protection scope, those skilled in the art
Member can also be changed its part, as long as it does not exceed the essence of this patent, within the protection scope of the present patent.
