Abstract
The utility model belongs to the motor field, concretely relates to axle and bearing clearance complex motor, including the stator, cooperate with the stator that rotor, the diaxon be connected hold, front end housing and rear end cap, wherein, two bearing position are connected in front end housing, rear end cap and with front end housing, rear end cap interference fit, and the scope of the magnitude of interference is 0.035mm~0.05mm, the rotor includes a pivot, and pivot movable mounting is between the diaxon holds, still be provided with the oil blanket between the bearing in front end housing and the front end housing. The utility model discloses use traditional bearing of solution and end cover to fall out the room as clearance fit, easy end cap bearings in the past, the rotor is axial displacement from beginning to end, influences the technical problem such as installation of motor.
Description
Technical field
The utility model belongs to machine field, is specifically related to the motor that a kind of axle coordinates with bearing clearance.
Background technology
Motor refers to a kind of calutron realizing electric energy conversion according to the law of electromagnetic induction or transmit; Its Main Function produces driving torque, and as the power source of electrical appliance or various machinery, its Main Function utilizes electric energy conversion for mechanical energy.In prior art, there is front end housing bearing and easily loosen in bearing chamber, even come off, affect the assembling of motor, and useful life.In view of this, the motor that the applicant provides a kind of axle to coordinate with bearing clearance, this case produces thus.
Utility model content
The purpose of this utility model is the motor providing a kind of axle to coordinate with bearing clearance, and to solve traditional bearing and end cap for matched in clearance, easily bearing with end cover room drops out in the past; Rotor can not fore-aft travel, affects the technical problems such as the installation of motor.
For realizing above-mentioned technical problem, the technical scheme that the utility model specifically provides is: the motor that a kind of axle coordinates with bearing clearance, the rotor, two bearings, front end housing and the rear end cap that comprise stator, be connected with stator; Wherein, described two bearings is positioned at front end housing, rear end cap being connected with front end housing, rear end cap interference fit, and the scope of the magnitude of interference is 0.035mm ~ 0.05mm; Described rotor comprises a rotating shaft, and rotating shaft and two bearings endoporus adopt matched in clearance, are movably installed between two bearings, and gap value is 0.015mm ~ 0.05mm; Also oil sealing is provided with between bearing in described front end housing and front end housing.
Further, described stator exposes in air, and described front end housing and rear end cap are fixed on stator by screw rod.
Further, described rotating shaft can along two bearings axial displacement.
The beneficial effects of the utility model: described rotor is movably installed between front end housing and rear end cap, rotor like this can move front and back slightly, facilitates motor to assemble; The two ends of rotating shaft are connected with front end housing, rear end cap difference interference fit by two bearings, and bearing like this can not drop out in the bearing chamber of front end housing; Described stator exposes to air, convenient heat radiation, and saves material.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, what the utility model specifically disclosed is the motor that a kind of axle coordinates with bearing clearance, the rotor 2, two bearings 6, front end housing 3 and the rear end cap 4 that comprise stator 1, be connected with stator 1; Wherein, described two bearings 6 is positioned at front end housing 3, rear end cap 4 being connected with front end housing 3, rear end cap 4 interference fit, and the scope of the magnitude of interference is 0.035mm ~ 0.05mm; Described rotor 2 comprises a rotating shaft 5, and rotating shaft 5 and two bearings endoporus adopt matched in clearance, and be movably installed between two bearings 6, gap value is 0.015mm ~ 0.03mm; ; Oil sealing 7 is also provided with between bearing 6 in described front end housing 3 and front end housing 3.
Further, described stator 1 exposes in air, and described front end housing 3 and rear end cap 4 are fixed on stator by screw rod; Described rotating shaft 5 can along the axial displacement of two bearings 6 endoporus.
Rotating shaft 5 described in the utility model can, along the axial displacement of two bearings 6 endoporus, facilitate motor to assemble.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
