Abstract
A kind of plug-in type axle key direct-connection transmission structure, the front end of the motor shaft of motor is provided with keyway；The front-end of spindle of pump is in a tubular form and provided with keyway；The front end of motor shaft, which is inserted directly into inside the front end of main shaft, keyway, is provided with flat key, and motor shaft drives pump main axis by flat key.Motor shaft of this plug-in type axle key direct connection structure on motor is inserted directly into the spindle hole of the product such as oil pump or petroleum vapor recovery pump, motor shaft has larger dynamic fit clearance with pump spindle hole, utilize the smaller stationary fit gap between pump positioning step or cooperation adapter flange and motor flange, ensure that centering is installed, motor shaft drives pump spindle operation by flat key, direct-connection transmission is realized, reaches that motor is connected the big problem of space-consuming with pump using traditional shaft coupling on solution fuel charger.Using pump positioning step or flange and motor flange stationary fit centering is coordinated to install, solving to install causes that vibrating noise is big, fault rate is high, the short problem of service life with shaft assignment is unreliable.
Description
Technical field
The utility model is motor direct connection oil pump, a kind of direct connection of motor direct connection petroleum vapor recovery pump that petrol station fuel charger is used
Drive mechanism.
Background technology
The motor direct connection products such as motor direct connection oil pump, the motor direct connection petroleum vapor recovery pump used on current gas station fuel charger
Transmission is attached using traditional shaft coupling, generally existing takes fuel charger inner space greatly, and installation can not with shaft assignment
By causing, vibrating noise is big, fault rate is high, service life is short, based on this situation, a kind of axle key connection kind of drive of independent research
Solve above-mentioned deficiency.
Utility model content
In order to solve above-mentioned problems of the prior art, the utility model provides a kind of plug-in type axle key direct-connection transmission
Structure.
The utility model solves the technical scheme that its technical problem used：
A kind of plug-in type axle key direct-connection transmission structure, the front end of the motor shaft of motor is provided with keyway；The front-end of spindle of oil pump
In a tubular form and provided with keyway；The front end of motor shaft, which is inserted directly into inside the front end of main shaft, keyway, is provided with flat key, and motor shaft leads to
Cross flat key and drive main axis；The front side of motor is provided with the positioning step for making drive mechanism be installed with pump stationary fit centering；It is described
Bearing is provided between main shaft and the oil pump.
Compared to the prior art the utility model, the advantage is that：
Motor shaft of this plug-in type axle key direct connection structure on motor is inserted directly into the product such as oil pump or petroleum vapor recovery pump
In spindle hole, motor shaft has larger dynamic fit clearance with pump main shaft, utilizes pump positioning step or cooperation adapter flange and motor
Flange is less stationary fit gap, it is ensured that centering is installed, and motor shaft drives pump spindle operation by flat key, realizes that direct connection is passed
Dynamic, this plug-in type direct connection structure can shorten the distance of the connection between motor and pump product as far as possible, reach on solution fuel charger
Motor is connected the big problem of space-consuming with pump using traditional shaft coupling.It is quiet using pump positioning step or cooperation flange and motor flange
Centering is coordinated to install, solving to install causes that vibrating noise is big, fault rate is high, the short problem of service life with shaft assignment is unreliable.

Orientation shown in the drawings or position relationship, are for only for ease of description the utility model, rather than indicate or imply signified dress
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to the utility model
Limitation.
A kind of plug-in type axle key direct-connection transmission structure, the front end of the motor shaft 2 of motor 1 is provided with keyway；The main shaft 5 of oil pump 3
Front end is in a tubular form and provided with keyway；The front end of motor shaft 2, which is inserted directly into inside the front end of main shaft 5, keyway, is provided with flat key 4, electricity
Arbor 2 drives main shaft 5 to rotate by flat key 4；The front side of motor 1 is provided with the positioning table for installing drive mechanism pump stationary fit centering
Rank 6；Bearing is provided between the main shaft 5 and the oil pump 3.
Motor shaft of this plug-in type axle key direct connection structure on motor is inserted directly into the product such as oil pump or petroleum vapor recovery pump
In spindle hole, motor shaft has larger dynamic fit clearance with pump main shaft, utilizes pump positioning step or cooperation adapter flange and motor
Flange is less stationary fit gap, it is ensured that centering is installed, and motor shaft drives pump spindle operation by flat key, realizes that direct connection is passed
Dynamic, this plug-in type direct connection structure can shorten the distance of the connection between motor and pump product as far as possible, reach on solution fuel charger
Motor is connected the big problem of space-consuming with pump using traditional shaft coupling.It is quiet using pump positioning step or cooperation flange and motor flange
