Abstract
The utility model discloses a kind of motor improved structure, it includes main shaft, casing, rear end cap, drive end bearing bracket, and rear end cap and drive end bearing bracket are separately fixed at casing both ends, and rear-end of spindle is fixed on rear end cap by bearing, complete hollow out, front-end of spindle pass through drive end bearing bracket hollow out position among the drive end bearing bracket.The utility model is reasonable in design, motor only has one group of bearing, it is few that part is installed, material storing cost is reduced, assembling is also more easy, and electric machine main shaft with vehicle bridge when being connected, due to there was only two groups of bearings of motor and vehicle bridge, two points one cable architectures are formed after cooperation, concentricity is higher, and the transmission of motor and vehicle bridge is more steady.
Description
Technical field
Technical field of motors is the utility model is related to, more particularly, to a kind of motor improved structure.
Background technology
At present, used motor, motor include main shaft, drive end bearing bracket, rear end cap, casing, drive end bearing bracket and rear end on the market
Lid is separately positioned on casing both ends, and main shaft both ends are erected on drive end bearing bracket and rear end cap by bearing respectively.In use, motor master
Axle and gear-box（Or vehicle bridge）Connection, gear-box or vehicle bridge are designed with bearing, and two bearings of motor add box bearing（Or
Vehicle bridge bearing）, it is to be ensured that on the same line, precision and alignment error to part require higher, electric machine structure in the three center of circle
Complicated, installation difficulty height, cost are high.
Utility model content
Therefore, the present invention is solves above-mentioned the deficiencies in the prior art, and offer one kind is simple in construction, assembling is easy, can have
Effect improves main shaft and gear-box（Or vehicle bridge）The concentricity of connection, and the motor improved structure of cost can be reduced.
What the purpose of this utility model was realized in.
A kind of motor improved structure, including main shaft, casing, rear end cap, drive end bearing bracket, rear end cap and drive end bearing bracket are separately fixed at
Casing both ends, rear-end of spindle are fixed on rear end cap by bearing, complete hollow out among the drive end bearing bracket, before front-end of spindle passes through
End cap hollow out position.
Above-mentioned technical proposal can also be done following further perfect.
Further, the drive end bearing bracket is in a circular ring type.
The utility model is reasonable in design, and motor only has one group of bearing, and installation part is few, reduces material storing cost,
Assembling it is also more easy, electric machine main shaft with gear-box（Or vehicle bridge）During connection, due to there was only motor and gear-box（Or vehicle bridge）
Two groups of bearings, two points one cable architectures are formed after cooperation, concentricity is higher, motor and gear-box（Or vehicle bridge）Transmission it is more flat
Surely.
Brief description of the drawings
Fig. 1 is example structure schematic diagram.
Fig. 2 is the diagrammatic cross-section of embodiment.
Fig. 3 is embodiment and vehicle bridge attachment structure schematic diagram.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one, with reference to Fig. 1-3.A kind of motor improved structure, including main shaft 1, stator 2, rotor 3, casing 4, rear end
Lid 5, drive end bearing bracket 6, main shaft 1 are passed through on rotor 3 and fixed rotor 3, and rotor 3 is placed in stator 2, and stator 2 is placed in shell 4, institute
Complete hollow out among drive end bearing bracket 5 is stated, i.e. drive end bearing bracket 5 is in a circular ring type, and rear end cap 6 and drive end bearing bracket 5 are separately fixed at 4 liang of casing
End, the rear end of main shaft 1 are fixed on rear end cap 6 by bearing 7, and the front end of main shaft 1 passes through the hollow out position of drive end bearing bracket 5, and main shaft 1 is before
Pulse wheel 8 is provided with end, the connection speed sensor 9 of pulse wheel 8, the stator 2 is stator core, and stator core front end is fixed on
On drive end bearing bracket 5.
Electric machine main shaft 1 is connected transmission with vehicle bridge 10, and two points one are formed after bearing 7 and vehicle bridge bearing 11 cooperation of motor rear end
Cable architecture, concentricity is higher, and motor and the transmission of vehicle bridge 10 are more steady, because noise caused by vibrations is reduced.
