Description
Technical Field
The utility model relates to the technical field of motors, in particular to a supporting structure for fixing a rotating inner ring of an outer ring of a rear-end rotor.
Background
At present, the driving range of a pure electric vehicle cannot meet the requirement of a long distance due to the influence of factors such as small specific energy and high price of a power battery, and the range extender can effectively solve the problem of range anxiety of the pure electric vehicle and becomes a development trend of new energy vehicles at present. The range extender generally comprises an engine and a generator, some engines output power through a motor at the rear end, and a support and the like are needed to support and rotate the structure of the rotor, so that the whole structure is bulky, large in size and structure, and not beneficial to the development of miniaturization and light weight of the engine.
SUMMERY OF THE UTILITY MODEL
The utility model provides a supporting structure for fixing a rotating inner ring of an outer ring of a rear-end rotor, aiming at solving the problems that the conventional engine outputs power through a motor at the rear end, and a bracket and the like are required to support and rotate the structure of the rotor, so that the whole structure is bulky, large in size and structure, and not beneficial to the development of miniaturization and light-weight of the conventional engine.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
a supporting structure for fixing a rotating inner ring of an outer ring of a rear-end rotor comprises a rear-end cover plate, a rotor assembly, a rotor bracket and a bearing, wherein the rear-end cover plate comprises a front part and a protruding part, the front part is disc-shaped, the protruding part is a stepped shaft, the protruding part and the front part are coaxially arranged, and the rear-end cover plate is integrally formed; the protruding portion is kept away from anterior pot head and is equipped with the bearing, the cover is equipped with the rotor spider on the bearing inner race, be provided with the rotor subassembly on the rotor spider.
Preferably, the end of the rotor bracket is provided with a rotor pressure plate. Such an arrangement may prevent foreign matter from entering from the end of the rotor holder.
The utility model has the beneficial effects that:
according to the supporting structure for fixing the rotating inner ring of the outer ring of the rear-end rotor, which is provided by the utility model, the rear-end cover plate is integrated with the shaft structure, and plays a supporting role on the rotor through the rotor bracket, and meanwhile, a structural form without a motor rotating shaft is formed, so that the integral structure is greatly simplified, and the weight of the whole machine is reduced.
Drawings
Fig. 1 is a schematic structural diagram of a supporting structure for fixing an outer ring and an inner ring of a rear-end rotor according to an embodiment of the present invention;
in the figure, 1-rear end cover plate, 2-rotor pressure plate, 3-bearing, 4-rotor assembly, 5-rotor bracket, 6-front part and 7-projection.
Detailed Description
In order to explain the technical content, the achieved objects and the effects of the present invention in detail, the following description is made in conjunction with the embodiments and the accompanying drawings.
Examples
Referring to fig. 1, the present invention provides a supporting structure for fixing a rotating inner ring of an outer ring of a rear end rotor, which includes a rear end cover plate 1, a rotor assembly 4, a rotor bracket 5, and a bearing 3, wherein the rear end cover plate 1 includes a front portion 6 and a protruding portion 7, the front portion 6 is disc-shaped and is used for connecting with a casing; the protruding part 7 is a stepped shaft, the protruding part 7 and the front part 6 are coaxially arranged, and the rear end cover plate 1 is integrally formed; the pot head that anterior 6 was kept away from to protruding portion 7 is equipped with bearing 3, the cover is equipped with rotor support 5 on the 3 outer lanes of bearing, be provided with rotor subassembly 4 on the rotor support 5. The bearing 3 is axially restrained by one end abutting against a shoulder of the projection 7 and the other end of the bearing 3 being pressed against the end face of the outer race by a projecting ring in the rotor holder 5.
With the structure, the shaft structure of the protruding part 7 of the rear end cover plate 1 is fixed, and the outer ring of the bearing 3 connected with the shaft structure rotates along with the rotor bracket 5, so that the rotor assembly 4 rotates along with the rotor bracket. The structure enables the rear end cover plate 1 of the engine to be in supporting connection with the rotor support 5 through the bearing 3, and meanwhile, the rotation of the rotor assembly 4 can be achieved, so that the structure of the motor rotating shaft is simplified, a structural form without the motor rotating shaft is formed, the integral structure is greatly simplified, and the weight of the whole machine is reduced.
Further, a rotor pressing plate 2 is arranged at the end part of the rotor bracket 5. Such an arrangement can prevent foreign matter from entering from the end of the rotor holder 5.
Although the utility model has been described in detail above with reference to specific embodiments, it will be apparent to one skilled in the art that modifications or improvements may be made based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
