The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Embodiment one
In conjunction with shown in attached drawing 1-3, the connection structure of a kind of motor and pump head is present embodiments provided, can be applied in vapour
Vehicle field, for example, vehicle brake and door contact interrupter power source be typically all that compressed air is realized, and by motor and compressor
Pump head is directly connected to have become the trend that the two transmission is realized in this field, more specifically can be the nothing in new-energy automobile field
Oily scroll air compressor.Except of course that the motor of the present embodiment and the connection structure of pump head are suitable for all kinds of outside above-mentioned application
Connection between motor and pump head, more exemplary embodiments do not do excessive description.
The motor of the present embodiment includes the motor and pump head being connected with the connection structure of pump head, and motor includes 1 He of casing
Electric machine assembly, forms an installation cavity inside casing 1, and electric machine assembly is mounted in the installation cavity.
One end in 1 opposite end of casing of the present embodiment is connected with drive end bearing bracket 2, and the other end is connected with rear end cap 3；This reality
One of the improvement of connection structure for applying the motor and pump head of example is that drive end bearing bracket 2 extends along the direction far from rear end cap 3 pump
Head bracket 4, pump head bracket 4 are connected with pump head.That is, the drive end bearing bracket 2 of seperated connection originally and the design of pump head bracket 4 are integrated
Molding not only reduces assembly process, and without making the two be connected by connectors such as screws, reduction processing cost, and
Eliminate assembling deviation.
In addition, utility model people has found, the casing 1 of existing motor with drive end bearing bracket 2 be with casing 1 it is split type, need
Use is assembled after processing respectively again, processing cost is high and fit clearance will lead to biggish assembling deviation.Therefore the present embodiment is again
Electric machine structure is further improved, casing 1 and the design of drive end bearing bracket 2 are integrally formed, is i.e. casing 1, drive end bearing bracket 2 and pump
4 three of head bracket is an integral structure, and when processing is integrally formed, naturally it is also possible to see as before 1 machine-shaping of casing has
Between end cap 2 and pump head.The structure has further reduced required components when machine assembly, reduces assembly time,
Assembly cost is reduced, and also eliminates the existing assembling deviation for being present in drive end bearing bracket 2 and casing 1.
As shown in figure 3, the electric machine assembly of the present embodiment includes shaft 5, rotor 6 and stator 7；Rotor 6 is set in shaft 5
Outside, stator 7 is set in outside rotor 6；Wherein 5 one end of shaft passes through drive end bearing bracket 2 and is connected with pump head, and the other end of shaft 5 is worn
Cross the rear end cap 3 of motor.And the pump head of the present embodiment includes the Moving plate 8 and quiet disk 9 being connected, Moving plate 8 and above-mentioned 5 phase of shaft
Connection, quiet disk 9 are connected with pump head bracket 4.
Specifically, being integral with component after the 7 force fit casing 1 of stator of the present embodiment.Pacify on the left of shaft 5
Bearing is filled, be fixed in 1 left side bearing chamber space of casing and locks bearing with screw, bearing baffle, while realizing and turning
Axis 5 is connected and fixed with stator 7.It is pressed into rotor 6 on the right side of shaft 5 and is pressed into bearing.The loading of Moving plate 85 left-hand axis of shaft is stretched
Section and axial restraint.
Also, bearing chamber is processed in pump head centre, a bearing is installed in the left end of rotor 6, and inner ring is installed on
On axis, outer ring is installed in bearing chamber, and rotor 6 is packed into casing 1 from left to right, then is realized by pressing plate and consolidated to the axial direction of bearing
It is fixed, and then realize the fixation to machine shaft 5.The leftmost side outer end face of pump head is threaded pore structure, outside the quiet disk 9 of compressor
Edge corresponding position is machined with circular through hole, and the two can be realized by screw and is fastenedly connected；
Preferably, the rear end cap 3 of the present embodiment is threadedly coupled with casing 1, the spiral shell outside machine-shaping specifically on rear end cap 3
Line, in 1 right end machine-shaping internal screw thread of casing, naturally it is also possible to which the two is opposite.When assembly, 5 right end bearing of shaft is placed in rear end
In the bearing chamber of lid 3, appropriate bonding agent, fixed base, rotation rear end cap 3 to the two screw thread are filled in the thread of rear end cap 3
It is fully mated, complete the assembly of entire motor.To guarantee fiting effect, the size of twisting resistance is limited when screwing rear end cap 3, both
Energy is fully mated and does not damage screw thread by pressure.After the assembly is completed, the bonding agent solidification filling thread space in rear cover thread, realization prevent
Threaded connection loosens and waterproof effect.
Certainly the specific structure about motor and pump head has been the prior art well-known to those skilled in the art, therefore
Other than specifically improving, the present embodiment does not make mark to each component of motor and pump head, does not also make specific connection and closes
The description of system and positional relationship, those skilled in the art can voluntarily understand.
In conclusion being had the advantages that according to the connection structure of motor provided in this embodiment and pump head
1, motor case, drive end bearing bracket and pump head bracket are subjected to disjunctor design processing, original 3 parts is reduced to 1
Part part can preferably save processing cost, improve production efficiency；
2, motor case, drive end bearing bracket and pump head bracket can promote part processing in production and processing with one-pass molding
Precision reduces motor complete machine because complete machine caused by part's machining errors fails；
3, motor and pump head compatible front-end lid and pump head, pts wt is more split type to reduce 15% or more, and can be reduced 6
The extremely corresponding screw thread process of screw association；
4, the sealing between base and rear end cap can be better achieved with rear end cap using being threadedly coupled in base, cancel
The use of screw, structure are more simple and effective.
