The utility model has advantages of high assembly efficiency, simple structure and good sealing effect.
Description
Technical field
The utility model relates to the hermetically-sealed construction that connects of a kind of electric motor end cap and connected body, belongs to the technical field of the machinery of motor.
Technical background
The nut compression type is adopted in the connection of the connected body on the electric motor end cap usually, promptly offer external screw thread at the outer surface of the front end housing of motor, adopt clamp nut with the axial compression of connected body after being enclosed within the connected body that has centre bore on the front end housing from end cap, this connected mode efficiency of assembling is low, the screw thread place connects the O type circle sealing that only depends on radial end face with front end housing, sealing effectiveness is not good.
Summary of the invention
The utility model purpose is to provide a kind of electric motor end cap hermetically-sealed construction that can connect fast, problem such as solved under the efficiency of assembling that prior art exists, sealing effectiveness is not good.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs:
A kind of electric motor end cap hermetically-sealed construction that can connect fast, comprise shaft, front end housing, connected body, shaft stretches out by the centre bore of front end housing, inside at front end housing is provided with oil sealing, the outside of front end housing is provided with connected body, it is characterized in that front end housing is provided with the bulge loop that is used to block connected body, connected body is connected on the outer surface of end cap by bulge loop.
Be provided with oil seal seat and bearing pedestal in the front end housing of motor, in oil seal seat, be provided with oil sealing, the bearing of accepting shaft is set in the bearing pedestal.Connected body is set in the outer surface of motor front end housing, adopt the nut screwing type to compress connected body, the two ends of connected body are in respectively under nut and the clamping of front end housing radial end face, usually on the front end housing radial end face, also be provided with seal groove with dress O sealing ring, owing on the outer surface of front end housing, offer screw thread, hermetically-sealed construction should not be set herein, and the joint efficiency of this prior art therefore is low, and sealing effectiveness is poor.The utility model adopts the cassette structure to replace prior art compression type structure, makes efficiency of assembling improve greatly.The utility model is convexly equipped with bulge loop on the outer surface of front end housing, the clamping connected body of the radial end face by bulge loop and bulge loop or bulge loop and front end housing only needs during assembling connector inserted and get final product, and convenient and strength-saving, assembling is firm simultaneously.
In order to reach better connection effect, the utility model can plug Elastic clamping plate between described bulge loop and connected body, the comparatively preferred scheme of described Elastic clamping plate is to adopt elastomeric material to make, and connected body adopts Elastic clamping plate to insert clamping connected body better.
As preferably, the relative connected body of the radial outer end of described Elastic clamping plate turns up.Connected body can better insert like this, assembles more simply, and simultaneously the chucking power of Elastic clamping plate is bigger, and clamping is more firm.
As preferably, described elasticity splice be the chuck of garden ring-type.Be made into discoid can be so that connected body stressed more even.Above-mentioned Elastic clamping plate is also being made into several, and every can make that from different angle symmetry insertions the connected body the utility model is stressed more even.
In order further to improve the utility model, can have the radial seal groove of installing O RunddichtringO in the radially corresponding position of connected body and front end housing.
Can also have simultaneously the axial seal groove of installing O RunddichtringO at the axial opposite position of front end housing and connected body.
Like this, the utility model just is provided with the two seals circle in the front end housing and the connector part of motor, because motor front end housing and connected body contact area are bigger, can offer multiple-sealed structure at their radially opposite face simultaneously.
Therefore, the utlity model has characteristics such as efficiency of assembling height, simple in structure, good sealing effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings 1, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, a kind of electric motor end cap hermetically-sealed construction that can join fast, comprise shaft 2, front end housing 1, shaft 2 stretches out by the centre bore of front end housing, be provided with oil sealing 6 in the inside of front end housing 1, the outside of front end housing 1 is provided with connected body 3, it is characterized in that front end housing 1 is provided with the bulge loop 9 that is used to block connected body, and connected body 3 is connected on the outer surface of front end housing by bulge loop 9.Be inserted with Elastic clamping plate 4 between described bulge loop 9 and connected body.The radial outer end of clamping plate 4 deviates from the connected body direction and turns up, described clamping plate 4 are chuck, radially opposite position at connected body 3 and front end housing 1 offers a seal groove, be equiped with sealing ring 8 in the seal groove, have another seal groove on the radial end face of connected body 3 and front end housing, it also is equiped with a sealing ring 7.
