Fig. 2 is the enlarged drawing of the part A shown in Fig. 1.
Embodiment
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Referring to Fig. 1, the dimensional structure diagram of the threephase asynchronous provided for the utility model.Described three is different
Step motor 100 includes pedestal 1, is respectively arranged on the drive end bearing bracket 2 and rear end cap 3 at the two ends of pedestal 1, for connecting the pedestal
1 and the pin 4 and taper pin 5 and the sealing ring 6 that is located between the drive end bearing bracket 2 and the pedestal 1 of the drive end bearing bracket 2.
The pedestal 1 include housing 11 and from the side wall of the housing 11 close to one end of the drive end bearing bracket 2 towards away from institute
State multiple raised the 12 of the central axis direction of housing 11 extension.The drive end bearing bracket 2 and the rear end cap 3 are located at the two of the housing 11
End.
Specifically, in the present embodiment, described raised 12 be four, and certainly, in other embodiments, described raised 12 can
Think two, three, five or more than five several, can be configured according to the need for specific.
Specifically, four described raised 12 are circumferentially uniformly distributed using the axis of the housing 11 as the center of circle.Described raised 12
Circumferentially it is uniformly distributed but the uniform force of threephase asynchronous 100, reduces the probability of its loosening.
Referring to Fig. 2, being the enlarged drawing of the part A shown in Fig. 1.The drive end bearing bracket 2 includes the first lid 21 and described in
The side wall of first lid 21 towards away from first lid 21 central axis direction extend boss 22, the boss 22 with it is described
Projection 12, which is corresponded, to be set, and the quantity of the boss 22 is identical with raised 12 quantity.
Specifically, in the present embodiment, the boss 22 is four and using the center of first lid 21 as the center of circle
It is circumferentially distributed.
