Description

A kind of epoxy resin encapsulated frock without housing stator

Technical field

The present invention relates to electric machine structure field, particularly relate to a kind of epoxy resin encapsulated frock without housing stator.

Background technology

In servomotor field, market is to the insulation grade anti-corrosion of motor, the demand of shock resistance resistance to cracking and preferably electric property and mechanical strength grows with each passing day, so a lot of motor stator all uses epoxy sealing on market, and in current motor technology, motor stator epoxy sealing structure, comprise stator module, stator core and stator case, but it is different with mounting means according to the field of application, some motors do not need stator case, but motor stator component still requires encapsulated epoxy resin, under these circumstances, track ring epoxy resin embedding frock with housing just cannot use, this brings difficulty with regard to giving the production of motor.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of epoxy resin encapsulated frock without housing stator, simple to operate, the epoxy sealing operation without the stator of housing can be completed fast, simplify technical process.

The technical solution adopted for the present invention to solve the technical problems is: provide a kind of epoxy resin encapsulated frock without housing stator, comprise central mandrel, be enclosed within the lower jacket outside central mandrel and upper jacket, the outer circumference surface of described central mandrel is socketed with stator module, the outside of the stator core of this stator module is socketed with stainless steel outer sleeve, the lower end of described lower jacket is connected with the base of central mandrel and is wrapped the lower end of stainless steel outer sleeve and stator winding, described upper jacket is socketed in the upper end of stainless steel outer sleeve and stator winding, described stainless steel outer sleeve and lower jacket, between upper jacket, sealing ring is installed.

The upper end of described stator winding is provided with lead-out wire fixed head.

The position corresponding with the lower end of stator winding, the side of the base of described central mandrel has a charging hole from the bottom to top.

Between the side of the base of described central mandrel and lower jacket, sealing ring is installed.

Described sealing ring is O-ring seals.

The outer circumference surface of described central mandrel is big top and small bottom taper seat.

The both sides, lower end of described central mandrel are installed with screw from the bottom to top and are connected with lower jacket.

beneficial effect

The present invention relates to a kind of epoxy resin encapsulated frock without housing stator, simple to operate, the epoxy sealing operation without the stator of housing can be completed fast, simplify technical process.

Accompanying drawing explanation

Fig. 1 of the present inventionly partly cuts open structure chart;

Fig. 2 is central mandrel structure chart of the present invention.

Embodiment

Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.

As shown in Figure 1-2, embodiments of the present invention relate to a kind of epoxy resin encapsulated frock without housing stator, comprise central mandrel 1, be enclosed within the lower jacket 2 outside central mandrel 1 and upper jacket 3, the outer circumference surface of described central mandrel 1 is socketed with stator module, the outside of the stator core 6 of this stator module is socketed with stainless steel outer sleeve 4, the lower end of described lower jacket 2 is connected with the base of central mandrel 1 and is wrapped the lower end of stainless steel outer sleeve 4 and stator winding 5, described upper jacket 3 is socketed in the upper end of stainless steel outer sleeve 4 and stator winding 5, described stainless steel outer sleeve 4 and lower jacket 2, sealing ring 7 is installed between upper jacket 3.

The upper end of described stator winding 5 is provided with lead-out wire fixed head 8.

The position that the side of the base of described central mandrel 1 is corresponding with the lower end of stator winding 5 has a charging hole 10 from the bottom to top.

Between the side of the base of described central mandrel 1 and lower jacket 2, sealing ring 7 is installed.

Described sealing ring 7 is O-ring seals.

The outer circumference surface of described central mandrel 1 is big top and small bottom taper seat.

The both sides, lower end of described central mandrel 1 are installed with screw 9 from the bottom to top and are connected with lower jacket 2.

First in central mandrel 1, O-ring seals is loaded onto, the lower surface of lower jacket 2 is connected by screw 9 with the upper surface of the bottom of central mandrel 1, O RunddichtringO is loaded onto in the inner side of lower jacket 2, and release agent is sprayed in central mandrel 1 and lower jacket 2, then stator module is from top to bottom arranged on lower jacket 2, again O-ring seals is contained in back-off after on upper jacket 3 and is arranged on the upper end of stator module, finally on upper jacket 3, fill a lead-out wire fixed head 8.

When filling with epoxy, be by silicone tube with the charging hole 10(bottom central mandrel 1 as Fig. 2) be connected, then by silicone tube to suction epoxy resin in stator module, when the liquid level rising of epoxy resin reaches the upper transverse plane of lead-out wire fixed head 8, namely require stop pouring, or and the spontaneous curing that is heating and curing, remove central mandrel 1 after end to be solidified, lower jacket 2, upper jacket 3.
