Because the existence of breach 80; When on motor output shaft, producing axial force F; Axial force F is passed to the brush carriage 1 that is installed in the motor field frame 10 through bearing, and the masterpiece that is passed on the brush carriage 1 is used on the top surface 42,52,62 and 72 of bracing or strutting arrangement 20.Because the existence of breach 80; Bracing or strutting arrangement 20 reduces along the rigidity of axial direction; Support column 40 and 50 no longer can transmit axial force; Axial force F acts on support column 60 and 70 fully, and support column 60 and 70 quilts are strain greatly, makes bracing or strutting arrangement 20 absorb fully and perhaps significantly reduces the axial force F that is passed on the motor field frame 10 at least.
Fig. 9 is the brush carriage when the brush carriage that is mounted 1 applies axial force F 1 of acquisition from test and the axial rigidity curve of bracing or strutting arrangement 20 assemblies.In this test, from brush carriage 1 is inserted beginning in the motor field frame 10, measurement is applied to the axial force F on the brush carriage 1, thereby obtains the axial rigidity curve of brush carriage 1 and bracing or strutting arrangement 20 assemblies.Abscissa representes that brush carriage 1 is inserted into the distance in the motor field frame 10, and ordinate representes to be applied to the axial force F on the brush carriage 1.
Wherein, curve I representes to utilize the bracing or strutting arrangement 20 of the utility model first embodiment brush carriage 1 to be installed and the curve of acquisition.Test in axial direction gets into motor field frame 10 beginnings from brush carriage 1; In curve I; Initial a period of time that stage 1 expression brush carriage 1 gets in the motor field frame 10, at this moment between in, brush carriage 1 does not also contact bracing or strutting arrangement 20; The axial force F that brush carriage 1 is applied roughly is used to overcome the friction between the inner surface of flange 12 and motor field frame 10 of brush carriage 1; So curve I keeps level in this stage 1, be substantially equal to the frictional force between the inner surface of flange 12 and motor field frame 10 of brush carriage 1.Along with brush carriage 1 begins to contact bracing or strutting arrangement 20; Particularly; After touching the top surface of support column of bracing or strutting arrangement 20; If want brush carriage 1 to continue in axial direction to move, then need overcome the elastic deformation force of four support columns of bracing or strutting arrangement 20, increase so make the mobile required axial force F of brush carriage 1 continuation be linear in the time after the stage 1.
Reference curve II again, expression utilizes the bracing or strutting arrangement 20 of the utility model second embodiment and the curve that obtains.Still in axial direction get into motor field frame 10 beginnings from brush carriage 1; In the stage 1; Just before brush carriage 1 touches bracing or strutting arrangement 20, identical with above-mentioned curve I, the axial force F that brush carriage 1 is applied is substantially equal to the frictional force between the inner surface of flange 12 and motor field frame 10 of brush carriage 1; Promptly in the stage 1, curve II overlaps with curve I.Yet; Utilization is according to the bracing or strutting arrangement 20 of second embodiment; After brush carriage 1 touches the support column of bracing or strutting arrangement 20 because two support columns 40 of bracing or strutting arrangement 20 are provided with the top elastic piece structure with 50 on the top, continue that shifting brush support 1 need overcome be support column 60 with 70 elastic deformation force and with the support column of not establishing the top elastic piece structure 40 compare with 50 elastic deformation force much little the elastic deformation force's and; This makes axial force F be far smaller than the elastic deformation force according to four support columns of the bracing or strutting arrangement 20 of first embodiment; So as shown in Figure 9, though also being linear, axial force F increases, the slope of curve II in the stage 2 after the stage 1 is less than curve I; Just, the axial force F that needs has reduced.After the top shell fragment on support column 40 and 50 tops is badly deformed; Promptly get into the stage 3 of curve II; With identical according to the bracing or strutting arrangement 20 of the utility model first embodiment; That shifting brush support 1 need overcome is the elastic deformation force of four support columns of bracing or strutting arrangement 20, so the slope of curve II increases to the slope of curve I.
By above-mentioned; According to the bracing or strutting arrangement 20 of second embodiment of the utility model through on two relative support columns, the top elastic piece structure being set; Allow the bigger axial deformation of bracing or strutting arrangement 20, therefore flexible more axial support is provided, also therefore reduced tolerance single parts to brush carriage 1; Reduced and the corresponding confining force of maximum allowance, further reduced cost.
According to the bracing or strutting arrangement that is used for the motor brush support of the utility model, can simplify the installation of brush carriage in motor field frame of motor, for brush carriage provides reliable flexible axial support.That said bracing or strutting arrangement has is simple in structure, to the advantage that tolerance is low, cost is low of parts processing and manufacturing.Especially reduced manufacturing requirement, reduced casing thickness, reduced the manufacturing cost of motor field frame motor field frame.
