Show, radial width is 0.5mm to 2mm, no more than the 75% of seam thickness.
As shown in Figure 4 and Figure 5, the surface of end cap 10 is provided with glue filling opening 31, to irrigate asphalt mixtures modified by epoxy resin into epoxy channels
Fat.Glue filling opening 31 is close to epoxy channels, a diameter of 1mm to 3mm of glue filling opening, slightly larger than the width of epoxy channels,
In order to which epoxy resin energy smoothness is passed through in passage, glue filling opening 31 uses screwed hole, and screw can be used after pouring into epoxy resin
Block, flowed out before avoiding epoxy resin cure.
There is epoxy resin in the epoxy channels of the present invention, epoxy resin is a kind of binding agent, is generally in a liquid state, its
Cohesive force is mainly chemical adhesion, can be used to bonding metal, manufacturability and good economy performance, resistance to compression, bending resistance, tension after solidification,
Modulus of elasticity is suitable with cast iron, and compression force direction reaches as high as 1200kg/cm^2 up to 1300kg/cm^2, direction of pull.Epoxy
Resin bonds that to form new casing seam (now de- without coating on casing seam 21 with casing seam after solidifying in its passage
Mould agent, releasing agent is coated with only on end cap seam 11).The seam has high-axiality.
Below by taking vertical mounting industrial motor as an example, the implementation of the present invention is introduced：
1st, rear end cap seam 11 applies with the right opposite of casing seam 21 and end face and spreads releasing agent, to prevent end cap 10 and epoxy
Resin-bonding；
2nd, advance mounted casing 20 and stator module are sling, one end is arranged on bottom down, by this end end cap 10, and
Screw on screw, it is not necessary to it is urgent, closed as long as casing 20 and end cap 10 are matched somebody with somebody；
3rd, dummy shaft 40 is put into the stator, makes the inner circle of 42 face stator core of stator contact face 50 of dummy shaft, under dummy shaft 40
Portion's bearing chamber contact surface 41 and this face of end bearing with end cover room 12.Stator contact face forms gap with the inner cylinder face of stator core 50
Coordinate, bearing contact surfaces form gap with drive end bearing bracket bearing chamber 12 and coordinated, and gap value is 0.01mm to 0.03mm；
4th, other end end cap 10 is installed, between the bearing with end cover room 12 and the face of dummy shaft upper bearing (metal) room contact surface 41 and formation
Gap coordinates, and gap value is 0.01mm to 0.03mm；
5th, the screw of urgent both ends end cap 10, because dummy shaft 40 has high-axiality, now electric motor end cap 10 and casing 20
High-axiality position is in；
6th, epoxide-resin glue is poured into from the outside glue filling opening 31 of casing 20, makes epoxy resin in casing seam 21 and end cap seam
Flowing in 11 epoxy channels formed is until passage is all filled.Treat that epoxy resin all solidifies, because of the ring after solidification
The mechanical property of oxygen tree fat is close with cast iron, is bonded in after epoxy resin cure on casing seam 21 equivalent to by casing seam 21
It is adjusted to the size of high-axiality；
7th, the screw of lower end cap 10 is unclamped, dummy shaft 40 and end cap 10 are taken out below the motor sling, then puts down and slings
The stator module of casing 20 unclamp the screw of top end cap 10, take out other end end cap 10；
8th, stator module is sling again, one end end cap 10 is coordinated into upper casing 20 from below, and tightens screw, is put into rotor
Axle and core assembly, other end end cap 10 is installed again.Now motor has good axiality, high-axiality industrial electro
Machine is completed, and the industrial motor has less electromagnetic consumable and mechanical loss, and motor performance and motor reliability are compared with general industry
Motor has been lifted.
Example embodiment is vertical installation motor, is only shown as one of which embodiment of the present invention, in fact, this
The involved high-axiality motor of invention has various other embodiments.
For example, glue filling opening 31 open up mode just have it is a variety of.As shown in fig. 6, glue filling opening 31 opens up position according to mounting means
Difference can also be in the side of casing 20, if horizontal installation, glue filling opening 31 can select to be opened in perpendicular to the ground upwardly-directed.Fill
Glue hole 31 can also be taken various forms, and such as latch well format, pin replacement screw can be inserted after epoxy resin is poured into be prevented
Epoxy resin flows out.
Shown scheme installation time is influenceed by epoxy cure time, and different type epoxy cure time is not
Together, it can be selected according to actual conditions, can also suitably be heated to accelerate epoxy cure time, carried in assembling process
Rise industrial motor assembling speed.
The present invention is not limited to use epoxy resin and releasing agent, has the material of corresponding mechanical strength and curing characteristics equal
It can be used as to substitute and use.
As can be seen from the above description, the above embodiments of the present invention realize following technique effect：
Motor in the present invention includes end cap 10 and casing 20, due to being provided with end cap seam 11, casing 20 on end cap 10
On be provided with casing seam 21, and it is nested between end cap seam 11 and casing seam 21 set, be used to accommodate positioning glue to be formed
Placed channel 30, so, by end cap seam 11 it is nested with casing seam 21 after, into placed channel 30 injection positioning glue,
Flowing, now, can after 30 curing molding of placed channel up to uniformly filling up placed channel 30 in placed channel 30 for positioning glue
To realize the positioning of the relative position between casing 20 and end cap 10, and then ensure between end cap seam 11 and casing seam 21
Axiality, solve the problems, such as that the axiality of motor of the prior art is poor.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
