Existing motor end cap structure is mainly the cast structure that electric motor end cap and bearing chamber are integrated, and exploitation different model motor need to be developed different end cap casting dies, can't be general when changing bearing type; And existing electric motor end cap and the integrated design of bearing chamber be subjected to the impact of motor assembly technology without vibration-damping function, and degree is bad with one heart to make motor may have rotor after installation, thereby causes radial force uneven, vibrates bigger than normally, increased noise of motor.
The utility model content
Based on this, be necessary defective and deficiency for prior art, provide the dismountable seriation motor end cap structure of a kind of bearing chamber to save development cost, reduce the vibration that the motor radial load causes, reduce noise of motor.
Be the electric motor end cap of realizing that the utility model purpose provides, comprise cover plate and at least one bearing chamber, be threaded connection between described cover plate and the described bearing chamber.
Among embodiment, described bearing chamber is a plurality of therein, and described a plurality of bearing chamber internal diameters are different, and external diameter is identical.
Among embodiment, the middle part of described cover plate is provided with groove, is provided with the first gas thread on the madial wall of described groove, is provided with second gas thread corresponding with described the first gas thread on the outer wall of described bearing chamber therein.
Among embodiment, be provided with fastening glue on the first gas thread of described cover plate and the second gas thread of described bearing chamber therein.
Among embodiment, the axial length of the groove of described cover plate is less than or equal to the axial length of described bearing chamber therein.
Therein among embodiment, between the bottom surface of the bottom surface of described cover plate and described bearing chamber, also be provided with the elastic damping rubber blanket.
Among embodiment, the shape of cross section of the groove of described cover plate is circular therein, and described bearing chamber is a hollow cylinder.
Among embodiment, the bottom of described cylinder shape groove also is provided with cylindrical dashpot therein, and the diameter of described cylindrical dashpot is less than the diameter of the groove of described cover plate.
The beneficial effects of the utility model: the bearing chamber of electric motor end cap of the present utility model is detachable, can design a series of electric motor end cap, can require to change separately bearing chamber according to generalization, need not again to develop end cap, thereby reduces cost; Reduce the vibration that the motor radial load causes, reduce noise of motor.
Description of drawings
For the purpose, technical scheme and the advantage that make the dismountable seriation electric motor end cap of the utility model bearing chamber clearer, below in conjunction with concrete drawings and the specific embodiments, the dismountable seriation electric motor end cap of the utility model bearing chamber is further elaborated.
Fig. 1 is the cross-sectional schematic of an embodiment of electric motor end cap of the present utility model;
Fig. 2 is that the master of electric motor end cap shown in Figure 1 looks schematic diagram.
Embodiment
An embodiment of the dismountable seriation electric motor end cap of the utility model bearing chamber, extremely shown in Figure 2 such as Fig. 1.
The utility model electric motor end cap comprises cover plate 100 and at least one bearing chamber 200, is threaded between described cover plate 100 and the described bearing chamber 200.Described bearing chamber 200 can be for a plurality of, and described a plurality of bearing chambers are that a series of internal diameter is different, the bearing chamber that external diameter is identical.Present embodiment provides a kind of dismountable electric motor end cap, and the bearing chamber of the corresponding different inner diameters size of the bearing of different model when motor is changed bearing designation, only need select described end cap cover plate to get final product with the described bearing chamber of the corresponding model of bearing is fixing.Arrange like this and can change separately bearing chamber according to the generalization requirement and get final product, need not again to change whole end cap, cost significantly reduces.
Preferably, as an embodiment, the middle part of described cover plate 100 is provided with groove 110, is provided with the first gas thread 1101 on the madial wall of described groove 110, is provided with second gas thread 201 corresponding with described the first gas thread on the outer wall of described bearing chamber 200.Present embodiment middle (center) bearing chamber is arranged in the groove of end cap cover plate.
Preferably, as an embodiment, be provided with fastening glue on the first gas thread of described cover plate and the second gas thread of described bearing chamber.During use; when cover plate is connected with described bearing chamber; the first gas thread at cover plate is smeared fastening glue; simultaneously smear fastening glue at the second gas thread of bearing chamber, when rotation made the gas thread engagement, fastening glue is curing molding also; can make so tightr that cover plate is combined with bearing chamber; avoided because described gas thread connects the vibration that is not closely caused, described end cap 100 and described bearing chamber 200 have been formed protection, improved the motor serviceability.
Preferably, as an embodiment, the axial length of the groove 110 of described cover plate 100 is less than or equal to the axial length of described bearing chamber 200.The installation that makes things convenient for bearing chamber is set like this, is convenient to hand.
Preferably, as an embodiment, between the bottom surface of the bottom surface of described cover plate 100 and described bearing chamber 200, also be provided with elastic damping rubber blanket 400.Elastic damping rubber blanket 400 is arranged on the bottom of described cylinder shape groove 110 and the contacted position, baseplane of described bearing chamber 200.Elastic damping rubber blanket and fastening glue cooperate can reduce the vibration that the motor radial load causes, reduces noise of motor.
Preferably, as an embodiment, the shape of cross section of the groove 110 of described cover plate 100 is circular, and described bearing chamber 200 is a hollow cylinder.
Preferably, as an embodiment, the bottom of described cylinder shape groove also is provided with cylindrical dashpot 111, and the diameter of described cylindrical dashpot 111 is less than the diameter of the groove 110 of described cover plate.Described cylindrical dashpot has formed an air barrier between described cover plate and described bearing chamber, reduce the motor vibrations to the damage that described cover plate causes, and makes things convenient for simultaneously the dismounting of bearing chamber.
The bearing chamber of electric motor end cap of the present utility model is detachable, and the electric motor end cap of a series of different inner diameters can be set, and can require to change separately bearing chamber according to generalization, need not again to develop end cap, thereby reduces cost; Reduce the vibration that the motor radial load causes, reduce noise of motor.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
