Abstract
The utility model relates to the technical field of motors, and the objective of the utility model is to provide an enhanced motor connecting bracket. The enhanced motor connecting bracket comprises a motor shaft fixing base. A shaft hole is formed in the central portion of the motor shaft fixing base. Two sides of the motor shaft fixing base are extended outwards to form a connecting lug connected with a motor housing. The outer end of the connecting lug is provided with a connecting hole. An annular groove is arranged around the shaft hole in the motor shaft fixing base. Through the annular groove, the strength of the motor shaft fixing base itself and the connecting strength between the motor shaft fixing base and the connecting lug can be enhanced, so the vibration during motor rotation can be effectively resisted to weaken the transmission of the vibration so as to prevent resonance from occurring inside the motor, so that the service life of the motor can be improved.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of reinforced motor connection bracket.
Background technology
Motor on dust catcher when in use, motor internal rotor rotating speed is very high, motor can produce vibration in high speed rotating, vibration is the very large factor that affects electrical machinery life, therefore how to reduce the vibration that electric machine rotation brings and become the important topic in design of electrical motor, especially the vibration that rotor rotation produces is easy to be delivered on motor housing, thereby cause resonance, this resonance is very strong to the destructiveness of motor, the shell of the motor in dust catcher connects by electric machine support at present, yet common electric machine support is because self intensity is limited, be easy to the vibration of rotor to pass to motor housing, thereby cause resonance and affect motor useful life.
Chinese patent Granted publication number: CN202997762U, June 12 2013 Granted publication day, a kind of electric machine support is disclosed, be arranged on motor main body output, draw together base and be fixed on the cover plate on described base, offering and hold the through hole that described motor main body output shaft passes on base, through hole offers the first installing hole around, on institute's cover plate, bearing is installed, bearing is coaxial with described through hole.This kind of electric machine support, is comprised of base and cover plate, simple in structure, improves its run stability energy.Its weak point is this kind of electric machine support self undercapacity, easy transmitting vibrations, thus cause motor integral body to resonate, have a strong impact on the useful life of motor.
Utility model content
The utility model easily passes to motor housing vibration in order to overcome electric machine connecting support of the prior art, cause resonance and affect the motor deficiency in useful life, provide a kind of self intensity large, can effectively reduce motor oscillating, avoid motor housing to resonate, thereby improve the motor reinforced motor connection bracket in useful life.
To achieve these goals, the utility model adopts following technical scheme:
A kind of reinforced motor connection bracket, comprise motor shaft holder, the center of described motor shaft holder is provided with axis hole, the both sides of described motor shaft holder stretch out and form the attachment lug being connected with motor housing, the outer end of described attachment lug is provided with connecting hole, and the axis hole on described motor shaft holder is provided with annular groove around.Annular groove can increase the intensity of motor shaft holder self, and with the bonding strength of attachment lug, thereby the vibration that can effectively resist electric machine rotation weakens the transmission of vibration, thereby prevents that motor internal from resonating, thereby the useful life of raising motor.
As preferably, on two attachment lugs, be arranged with reinforcement pit.Because attachment lug integral body is longer, strengthening pit is in order to increase the intensity of attachment lug self, thereby reduces the vibration transmission of rotor, improves the whole service life of motor.
As preferably,, on described attachment lug, at the position of strengthening between pit and axis hole, be also provided with location hole.Location hole is connected with the impeller of determining in motor of dust collector, so just determining impeller, motor housing connection bracket, motor housing, all connects into an integral body, and bonding strength is large, and overall performance is stable, reliable.
As preferably, in motor shaft holder, be provided with bearing.Bearing plays the effect of positioning supports to motor shaft, the resistance in the time of can also reducing motor shaft rotation.
Therefore, the utlity model has self intensity large, can effectively reduce motor oscillating, avoid motor housing to resonate, thereby improve the motor beneficial effect in useful life.
