In electric pallet truck in the past, usually adopt electrical motor to captive joint with gear case, the shell and the gear case that are electrical motor all are fixed on the bearing cone, and the outer ring of this bearing is fixed with a terminal pad that is used for connecting car body, and the running of gear case is realized by shaft of motor.Because electrical motor and gear case link into an integrated entity, so do not have relative motion relation between them, but action simultaneously.In addition, because the outer ring of bearing is connected with car body by terminal pad,, that is to say that driver element can rotate when car body was motionless so driver element and the car body be made up of electrical motor and gear case just can have one along the circumference degree of freedom on the bearing center axle.In order to realize turning to of driver element, the prior art electric pallet truck has been fixed a spindle arm on the shell of electrical motor, spindle arm is captiveed joint with turning to permanent seat, and turn to permanent seat to be connected with handgrip, so, in fact turn to permanent seat and spindle arm to can be used as a part, and prior art drive and turns to the permanent seat rotation to make whole driver element realize turning to just by rotary handle into electrical motor.In steering procedure, since electrical motor with turn to permanent seat, spindle arm and gear case to connect as one, therefore electrical motor needs rotation equally in steering procedure, this just makes the power lead of electrical motor constantly back and forth be easy to generate wearing and tearing in the divertical motion, even power lead can take place, thereby caused great infringement for the in-use performance of car load because of tired situation about rupturing.
The utility model content:
The technical problems to be solved in the utility model is, provide a kind of electrical motor can not rotate along with the rotation of gear case, thereby avoid the power lead of electrical motor that wearing and tearing and fracture by fatigue take place, effectively improve the electric pallet truck electrical motor connecting device of car load in-use performance.
Technical solution of the present utility model is that a kind of electric pallet truck electrical motor connecting device with following structure is provided: it comprises electrical motor, gear case and bearing, be installed in motor bracket on the car body, be connected the transition disc, two of motor bracket and electrical motor by the interconnective sprocket wheel of chain and a handgrip deflecting bar; Captive joint with motor bracket in the outer ring of described bearing, bearing cone is captiveed joint with the top of gear case; A described sprocket wheel is installed in the top of gear case; The bottom of described handgrip deflecting bar is fixedly connected on the front end of car body by another sprocket wheel.
After adopting above structure, compared with prior art, the utlity model has following advantage: all captive joint different with bearing cone with the shell of electrical motor in the prior art electric pallet truck electrical motor connecting device and the top of gear case, electrical motor in the utility model is installed on the car body by transition disc and motor bracket, thereby driving two sprocket rotation at the handgrip deflecting bar makes in the gear case rotating process, electrical motor can not follow gear case to rotate together, it is the electrical motor reciprocal divertical motion not in the utility model, thereby the power lead of avoiding electrical motor produces wearing and tearing and fracture, the in-use performance of the car load that guarantees to know clearly.
Above-mentioned transition disc connects motor bracket and electrical motor refers to that described transition disc top links together by attaching screw and motor casing; Described transition disc bottom links together by mounting screw and motor bracket.
Above-mentioned handgrip deflecting bar bottom is fixedly connected on the car body front end by sprocket wheel and refers to, described car body front end is fixed with an anchor shaft, and the outside face of described anchor shaft is captiveed joint with the inner ring of oscillating bearing; Captive joint with sprocket wheel in the outer ring of described oscillating bearing; Captive joint with sprocket wheel as welding in described handgrip deflecting bar bottom.
Can fix a circlip for bore in the circular hole of above-mentioned sprocket wheel of captiveing joint with handgrip deflecting bar bottom.The effect of circlip for bore is to be used for blocking the oscillating bearing outer ring, thereby prevents the oscillating bearing play and influence divertical motion of the present utility model.
Can fix a pad between the bottom surface of the upper surface of above-mentioned circlip for bore and oscillating bearing outer ring.The effect of pad is in order to reduce the friction between circlip for bore and the oscillating bearing outer ring, thereby guarantees the alerting ability that the utility model turns to.
