Embodiment
The electric eddy current retarder of a kind of specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.But, the utility model should be understood as and be not limited to this mode of execution described below, and technical concept of the present utility model can combine with other known technologies or function other technologies identical with those known technologies and implements.
In the following description, in order to clear displaying structure of the present utility model and working method, to be described by many Directional words, but by the Word Understanding such as "front", "rear", "left", "right", " outward ", " interior ", " outwards ", " inwardly ", " axis ", " radial direction " for convenience of term, and word of limitation should do not should be understood to.
The Placement of rolling bearing of the prior art and transmission shaft is shown in Fig. 4.As shown in Figure 4, there is a step 19 inner side of axle sleeve 14, and there is a step 18 in the outside of transmission shaft.Two rolling bearings 15 are withstood on step, and utilize metal spacer ring 16 blind.Such rolling bearing 15 just ensure that inner ring and transmission shaft 13 are fixed, and outer ring and axle sleeve 14 are fixed.The technical problem that the Placement of rolling bearing of the prior art and transmission shaft is brought is that efficiency of assembling cannot improve.In order to solve this technical problem, below bearing arrangement disclosed in the utility model will be explained in detail.
Complicated in order to overcome retarder assembly process in prior art, the shortcoming that installation time is long, the utility model provides a kind of bearing arrangement for retarder, comprise: one first rolling bearing, the outer ring of this first rolling bearing is connected with a stator, and the inner ring of this first rolling bearing is connected with a transmission shaft, one second rolling bearing, the outer ring of this second rolling bearing is connected with this stator, and the inner ring of this second rolling bearing is connected with this transmission shaft; The one the second rolling bearings are connected by a bearing sleeve.
As shown in Figure 5, Fig. 5 is the structural representation of the electric eddy current retarder involved by the utility model.This electric eddy current retarder is made up of stators and rotators, and rotor and transmission shaft 22 keep relative position to fix.When electric eddy current retarder works, stator produces magnetic field, and when transmission shaft 22 rotarily drives rotor turns, cutting magnetic line produces induction current, and stator applies an electromagnetic force to rotor, thus produces braking moment.Stator is connected by two rolling bearings 26 with transmission shaft 22.Wherein the inner ring of rolling bearing or inner side are connected with transmission shaft 22, and the outer ring of rolling bearing is connected with stator.Because the shape of electric eddy current retarder is cylindrical in one haply, in the utility model, " inner side " of indication refers to the side near this cylindrical center axle, and " outside " refers to the side away from this cylindrical center axle accordingly.In a preferred embodiment, adopts fixing of axle sleeve 21 by one between the outside of stator and rolling bearing 26.When the rotor of this electric eddy current retarder and transmission shaft 22 rotate, stator, axle sleeve 21 keep geo-stationary.The effect of rolling bearing 26 is by stators and rotators decoupling zero.
Bearing arrangement disclosed in the utility model, utilizes a bearing sleeve to fix rolling bearing, stator and transmission shaft.This bearing sleeve comprises neck bush 24 and external bushing 23.Under the technical program, transmission shaft 22 need not reprocess step, its cross section roughly in a straight line, It greatly reduces the processing cost of transmission shaft 22.This bearing arrangement also comprises a stator axle sleeve 21, and the outer ring of the internal chamber wall of stator axle sleeve 21 and two rolling bearings 26 and bearing sleeve fixes.
The mode that two rolling bearings 26 and bearing sleeve are fixed together in the present embodiment is, stator axle sleeve 21 is processed a step 29, step 29 contacts with the outer ring of rolling bearing 26b, and rolling bearing 26a is fixed with axle sleeve 21 by an outer ring pressing plate 28 and screw 27.When pressing plate 28 couples of rolling bearing 26a in outer ring apply power, this power passes to the step 29 of external bushing 23, rolling bearing 26b, stator axle sleeve 21 successively from rolling bearing 26a.Be fixed together between outer ring pressing plate 28, rolling bearing 26a, bearing sleeve, rolling bearing 26b and stator axle sleeve 21 quilt.In fact, those of ordinary skill in the art should know the mode be fixed on by two component together also having other, as welding.In order to regulate the gap between stator and rotor, also designing two and regulating pad 25.
After rolling bearing 26, bearing sleeve and stator axle sleeve 21 three have assembled, the gap produced because of tolerance in prior art has not just been present in, and also just need not use metal spacer ring.Therefore this retarder directly can assemble transmission shaft in assembly process, and does not need first by means of a substitute determination size, then installs transmission shaft.Therefore compared with prior art, assemble flow is reduced to one assembly process by three original road assembly processes, and decrease excess step, efficiency of assembling promotes greatly.
Just preferred embodiment of the present utility model described in this specification, above embodiment is only in order to illustrate the technical solution of the utility model but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should within scope of the present utility model.
