Description
Technical field
The present invention relates to a kind of motor with plastic connecting components, more particularly to a kind of motor for improving assembling structure, change
The assembling structure entered between drive end bearing bracket, rear end cap and plastic connecting components.
Background technology
As shown in figure 1, having the motor of plastic connecting components at present, during locking plastic connecting components, rear end is locked successively respectively
Lid and drive end bearing bracket.During locking, due to plastic connecting components intensity difference, when coupling mechanism force is excessive, plastic connecting components are easily deformed, dress
The center line of the rear end cap being fitted in plastic connecting components produces skew, and particularly the axis hole on rear end cap there occurs skew, assembling
The parts such as machine shaft, rotor afterwards produce not coaxial situation, easily cause electrical fault, and, plastic connecting components are repaired
When, dismounting is difficult.
Drive end bearing bracket is aluminum component, is embedded into plastic connecting components using gap assembling mode, the more difficult alignment of cental axial position, is led
Cause drive end bearing bracket to press-fit to be difficult to be press-fit into place, the failures such as card machine, stall easily occurs in the axiality of influence motor assembling, motor.By
In the deflection that expands with heat and contract with cold of plastics is big.During summer, temperature is higher, and the size of plastic connecting components becomes big because of high-temperature expansion, disappears
The gap value consumed between drive end bearing bracket, causes drive end bearing bracket to press-fit difficulty, or even cannot normally assemble.Further, since in motor
Temperature is high, and plastic connecting components are permanently deformed in high temperature environments, and motor is carried out when needing to pull down plastic connecting components and drive end bearing bracket
During maintenance, drive end bearing bracket can be stuck in plastic connecting components, it is difficult to taken out, or even can only be using destruction plastic connecting components or drive end bearing bracket
Mode repaired again dismantling plastic connecting components and drive end bearing bracket, so not only lost time but also cost of idleness.
Further, since the assembling mode between electric machine casing and drive end bearing bracket, have that requirement on machining accuracy is high, assembly difficulty compared with
Big problem.
The content of the invention
A kind of electricity for improving assembling structure is provided it is an object of the invention to solve the above mentioned problem of prior art presence
Machine, changes the assembling mode of drive end bearing bracket, improves the axiality with machine shaft after drive end bearing bracket is assembled, and changes rear end cap and joins with plastics
Assembling mode between fitting, housing, improves the axiality with machine shaft after rear end cap is assembled, while convenient dismounting rear end
Lid, that is, improve the operation stability and reliability of motor, has been reduced the fault rate of motor.
What above-mentioned technical purpose of the invention was mainly solved by the following technical programs：The motor of assembling structure is improved,
Including motor body, the housing of motor body periphery is arranged on, is arranged on the drive end bearing bracket and rear end cap at the housing two ends, set
Plastic connecting components on the outside of the drive end bearing bracket and rear end cap, the drive end bearing bracket and rear end cap press-fit spacing in the plastics respectively
In connector, it is characterised in that be uniformly arranged a plurality of first connections near the position of the drive end bearing bracket on the plastic connecting components
Hole, is uniformly arranged a plurality of second connecting holes on the rear end cap, connector is passed through between the plastic connecting components and rear end cap
Connection, the connector sequentially passes through first connecting hole and the second connecting hole, the drive end bearing bracket and rear end being correspondingly arranged
The inner two ends respectively with the housing of lid contradict spacing cooperation.
Change the assembling mode of rear end cap, improve axiality with machine shaft after rear end cap assembling, change drive end bearing bracket with
Assembling mode between plastic connecting components, housing, improves the axiality with machine shaft after drive end bearing bracket is assembled, while convenient dismounting
Drive end bearing bracket, that is, improve the operation stability and reliability of motor, has been reduced the fault rate of motor.
Furthermore, it is understood that in the technical program, directly drive end bearing bracket is connected on plastic connecting components using connector, change
Become the scheme that prior art is connected to electric machine casing using rear end cap, improve the axiality with machine shaft after rear end cap is assembled.
During assembling drive end bearing bracket, plastic connecting components do not use the scheme of prior art to be connected with electric machine casing, but use plastic connecting components
Rear end cap is connected to by connector, by the cooperation of rear end cap and plastic connecting components, clamping motor housing makes electric machine casing pair
The inner of drive end bearing bracket carries out spacing, and the axiality of drive end bearing bracket and rear end cap and machine shaft is adjusted by machine shaft.
