Description

A closed generator casing and rotor for engineering vehicles

technical field

The invention designs a vehicle body accessory, in particular a closed generator casing and rotor for engineering vehicles.

Background technique

The working environment of some construction vehicles is relatively special, there is a lot of dust, and there will be a lot of water on the ground, such as sewage suction vehicles, sprinklers and some agricultural operation vehicles. This type of vehicle works as a traditional generator. Due to the existence of some holes, it is easy to enter dust and water, which greatly affects the working state and service life of the generator. In addition, the rotor of many traditional engineering vehicles is composed of coil winding, and the cost is relatively high. High, so it is necessary to design a special generator casing and rotor for engineering vehicles.

Detailed ways

For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below.

Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment is formed by sequentially splicing rear end cover 1, stator 2 and front end cover 3. The rear end cover 1 and front end cover 3 are all integrally formed by aluminum casting, and only the ports at both ends are provided with through holes, which are fully enclosed. The shell prevents the entry of dust and water, which increases the safety of operation and increases the service life. The center of the rear end cover 1, stator 2 and front end cover 3 is connected with a rotating shaft 7, and a rotor 14 is arranged on the rotating shaft 7; the front end cover 3 One side is provided with a fan 8, the other side of the fan 8 is provided with a pulley 9, and the other end of the pulley 9 is provided with a nut 10.

In the enclosed generator housing and rotor for an engineering vehicle of the present invention, the rotor 14 is provided with a plurality of magnetic sheets 12, and a separation groove 13 is arranged between adjacent magnetic sheets 12, and the magnetic sheets 12 are permanent magnets or magnets. , The replacement of the magnet can greatly reduce the production cost, and can reduce the rotation resistance of the rotating shaft to a certain extent. The rotating shaft 7, the magnetic sheet 12 and the isolation groove 13 form the rotor.
