Description
Technical field
The utility model belongs to technical field of transmission machinery, is related to a kind of motor, in particular to a kind of motor transmission shaft
Connection structure.
Background technique
Motor is commonly called as motor, is a kind of equipment for converting electrical current into mechanical energy, it is to use the power on coil to generate rotation
Magnetic field simultaneously acts on rotor and forms electro-magnetic motor force rotation torque, by using power supply difference to be divided into direct current generator and alternating current generator, electricity
Motor in Force system is largely alternating current generator, can be synchronous motor either asynchronous machine, motor mainly by stator with
Rotor composition, the direction of electrified wire movement under force in magnetic field is related with magnetic induction line direction with current direction, and motor work is former
Reason is that magnetic field rotates motor the effect of electric current stress.The transmission shaft of motor is typically all that integral structure directly stretches out at present
Outside motor, therefore there are problems that being not easy to replace after transmission shaft crumbles.
Summary of the invention
The purpose of this utility model is to provide a kind of motor transmission shaft more for the above-mentioned problems in the prior art
Change more convenient connection structure.
The purpose of this utility model can be realized by the following technical scheme: a kind of connection structure of motor transmission shaft, should
Structure includes end cap, rotor assembly and outrigger shaft, bearing is arranged in the end cap, between the rotor assembly and end cap
It is connected by bearing fit, which is characterized in that one end of the rotor assembly passes through bearing and is located in end cap, the rotor
The top of component offers card slot, and the bottom of the outrigger shaft has the column matched with card slot shape, passes through column and card
The cooperation of slot makes rotor assembly that outrigger shaft rotation be driven to realize power transmission, and securing elongated axis has been provided on the end cap and has been made
Snap ring.
Its advantage of the connection structure of this motor transmission shaft are as follows: direct relative to the motor shaft in traditional motor rotor component
It stretches out outside electric motor end cap, rotor assembly shortening is located in end cap by the utility model, and by one end inserting end of outrigger shaft
It realizes it with rotor engagement to be driven, transmission is realized by card slot and column cooperation between outrigger shaft and rotor, wherein two
The cooperation kind of drive of person can be driven for cross, blossom type or square, then prevent outrigger shaft in such a way that snap ring fastens
It falls off, therefore this motor can be convenient directly replacement without disassembly motor body, practical performance is more after outrigger shaft damage
It is good.
In a kind of connection structure of above-mentioned motor transmission shaft, it is arranged on the outrigger shaft and is matched with end cap
Rubber ring.The design of rubber ring can prevent the outflow of lubrication oil inside motor.
In a kind of connection structure of above-mentioned motor transmission shaft, limiting slot, the end are offered on the outrigger shaft
The upper surface outwardly convex of lid forms the stop collar matched with limiting slot.It is formed it by the cooperation of limiting slot and stop collar
Position limiting structure prevents from transmitting shakiness caused by outrigger shaft radial deflection, outrigger shaft is made to be not easy to be worn.
In a kind of connection structure of above-mentioned motor transmission shaft, the material of the outrigger shaft is engineering plastics.
Compared with prior art, the connection structure of this motor transmission shaft is improved by the structure to transmission shaft makes its tool
Have the advantages that practical performance is more preferable and repair and replacement are convenient.
Detailed description of the invention
Fig. 1 is the partial sectional view of the connection structure of this motor transmission shaft.
In figure, 1, end cap；2, rotor assembly；3, outrigger shaft；4, bearing；5, card slot；6, column；7, snap ring；8, rubber ring；
9, limiting slot.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, the connection structure of this motor transmission shaft, which includes end cap 1, rotor assembly 2 and outrigger shaft 3,
It is arranged with bearing 4 in end cap 1, is cooperatively connected between rotor assembly 2 and end cap 1 by bearing 4, one end of rotor assembly 2 passes through
Bearing 4 and it is located in end cap 1, the top of rotor assembly 2 offers card slot 5, and the bottom of outrigger shaft 3 has and 5 shape of card slot
The column 6 matched makes rotor assembly 2 that the rotation of outrigger shaft 3 be driven to realize power transmission, end by the cooperation of column 6 and card slot 5
The snap ring 7 that securing elongated axis 3 acts on has been provided on lid 1.
It further describes in detail, in order to prevent the outflow of lubrication oil inside motor, is arranged on outrigger shaft 3 and is matched with end cap 1
Rubber ring 8；3 radial deflection of outrigger shaft causes transmission unstable in order to prevent, makes outrigger shaft 3 be not easy to be worn, opens on outrigger shaft 3
Equipped with limiting slot 9, the upper surface outwardly convex of end cap 1 forms the stop collar matched with limiting slot 9.
Wherein, the material of outrigger shaft 3 is by engineering plastics for replacing traditional metal material.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although be used more herein end cap 1, rotor assembly 2, outrigger shaft 3, bearing 4, card slot 5, column 6, snap ring 7,
The terms such as rubber ring 8, limiting slot 9, but it does not exclude the possibility of using other terms.The use of these items is only for more
Easily describe and explain the essence of the utility model；It is practical new with this for being construed as any additional limitation all
Type spirit is disagreed.
