Abstract
The invention discloses a connecting structure for connecting a motor end cover and shell double-stopper opening, which comprises an end cover and a seal gasket, wherein the end cover is connected with the front end of a motor shell; and the combining end surface of the end cover and the shell is provided with an outer-layer stopper opening and inner-layer stopper opening connecting structure. The invention obviously improves the connecting rigidity of the motor end cover and the shell, has good seal performance of the connecting position of the end cover and the shell and is adapted to a high-power motor installed by a flange.
Description
Technical field
The present invention relates to a kind of lid and housing end face draw bail, specifically, the present invention relates to a kind of electric motor end cap and housing draw bail.
Background technology
It is one of motor mounting means commonly used that flange is installed (not with footing), and it installs on the driven device with electric motor end cap seam flange.This connecting mode supports whole motor by end cap, needs enough intensity of being connected with of end cap self and end cap and housing and rigidity.The end cap of prior art and housing draw bail can satisfy the needs that the middle low power electric machine flange is installed, but for heavy-duty motor because the motor own wt is bigger, end cap and electric machine casing connect often deficiency of rigidity; In addition, the end cap of prior art and housing connection place poor sealing.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of simple in structurely, can improve end cap connects rigidity and sealing with housing electric motor end cap and housing draw bail.
The present invention is achieved through the following technical solutions technical goal.
Electric motor end cap and housing double stopper draw bail, it is made up of end cap, sealing gasket that the electric machine casing front end connects; Its improvements are: described end cap combines end face outer seam, internal layer seam draw bail is set with housing.
Described internal layer seam draw bail is that the internal layer male half coupling combines the little matched in clearance structure of end face fovea superior seam on the end cap with housing; Described outer seam draw bail is that the convex outer seam combines the little matched in clearance structure of end face fovea superior seam groove on the end cap with housing, and its end face is equipped with sealing gasket.
Described outer seam, internal layer seam central axis are coaxial.
The present invention compared with prior art has following good effect:
1, to connect rigidity higher for electric motor end cap and housing;
2, end cap and housing connection place good airproof performance.
Description of drawings
Fig. 1 is a structural profile schematic diagram of the present invention.
Embodiment
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
A kind of electric motor end cap double stopper draw bail shown in the drawings, it is the instantiation that is applied on the 55KW marine electric machine, end cap 1 combines end face outer seam 1.1, internal layer seam 1.2 draw bails is set with housing 3.Described internal layer seam 1.2 draw bails are that the internal layer male half coupling combines the little matched in clearance structure of end face fovea superior seam, fit clearance 0.01-0.02mm on the end cap 1 with housing 3; Described outer seam 1.1 draw bails are that the convex outer seam combines the little matched in clearance structure of end face fovea superior seam groove on the end cap 1 with housing 3, fit clearance 0.01-0.02mm, and its end face is equipped with sealing gasket 2; Outer seam 1.1, internal layer seam 1.2 central axis are coaxial.
The present invention is owing to adopted double stopper structure, electric motor end cap to connect the rigidity raising with housing; The sealing gasket of outer seam end face makes end cap and housing connection place sealing good.
