Abstract
The utility model relates to a driving mechanism of an electric grass pruning machine positioned in the back, which comprises a series excited machine, a connecting shaft, a main shaft and a flexible shaft connected between the connecting shaft and the main shaft, wherein a bracket is arranged on a casing of the series excited machine; a driving device composed of a small belt wheel, a belt, a big belt wheel and a shaft of the big belt wheel is arranged between an output shaft of the series excited machine and the connecting shaft; the shaft of the big belt wheel is connected with the bracket through a bearing, the upper end of the shaft of the big belt wheel is connected with the big belt wheel, and the lower end of the shaft of the big belt wheel is inserted into a shaft hole of the connecting shaft; the small belt wheel is connected with the output shaft of the series excited machine. The utility model achieves the goal of deceleration through first-level speed reducing transmission; as the series excited machine has high rotating speed of and good heat dispersion, the temperature rise of the series excited machine is under control, and the volume of the series excited machine is reduced. As the rotating speed of the main shaft and the rotating speed of a nylon rope can be reduced, the noise generated by the electric grass pruning machine positioned in the back using the utility model is reduced. The utility model has the advantages of simple structure and reliable performance.
Description
Technical field
The utility model relates to the transmission mechanism of the electronic grass pruning machine in gardens.
Background technology
The transmission mechanism of existing rear-mounted electronic grass pruning machine comprises series excited machine, connecting axle, flexible axle and main shaft, and the torque of series excited machine output is passed to main shaft by connecting axle, flexible axle, and driving the wire spool assembly by main shaft is the toolbox rotation.Above-mentioned transmission mechanism is as selecting high-revolving series excited machine under the condition of rated power that guarantees motor and rotating speed, rotating speed at the wire spool assembly that is driven by main shaft is higher, being connected certainly will be very fast as the nylon rope rotary speed of repairing careless cutter on the wire spool, produces noise therefrom.If under the condition of rated power that guarantees motor and rotating speed, select slow-revving series excited machine, though the rotating speed of main shaft can be reduced, wire spool assembly rotating speed reduces the noise of the rotation generation that makes nylon rope along with decline thereupon, but, certainly will require the volume of motor to increase for making electric machine temperature rise in index.
The utility model content
The purpose of this utility model is to propose a kind of like this transmission mechanism of rear-mounted electronic grass pruning machine, and it can select high-revolving series excited machine under the condition of rated power that guarantees motor and rotating speed, but the rotating speed of main shaft is lower relatively again.
The utility model comprise series excited machine, connecting axle, main shaft and be connected connecting axle and main shaft between flexible axle, for achieving the above object, the utility model is taked to be provided with support on the housing of series excited machine, be provided with the transmission device of forming by small pulley, belt, big belt wheel and big belt shaft between the output shaft of series excited machine and the connecting axle, big belt shaft is connected with support by bearing, its upper end is connected with big belt wheel, its lower end is plugged in the axis hole of connecting axle, and described small pulley is connected on the series excited machine output shaft.
Between above-mentioned big belt shaft and the connecting axle by screw lock.
Above-mentioned flexible axle and connecting axle lower shaft hole be connected and flexible axle connects with all taking profile being connected of main shaft axis hole.
Above-mentioned profile connects the two ends of taking flexible axle and is square, and the lower shaft hole of connecting axle is each square opening that matches with the upper and lower end of flexible axle with the axis hole of main shaft, and the upper and lower end of flexible axle inserts respectively in the axis hole of the lower shaft hole of connecting axle and main shaft.
The utility model reaches the purpose of reduction of speed by the one-level deceleration transmission, under the condition of rated power that guarantees motor and rotating speed, can select high-revolving series excited machine, uses high-revolving series excited machine, and in the electric machine temperature rise index, the volume of motor can reduce.Because the rotating speed of main shaft decreases, make application rear-mounted electronic grass pruning machine of the present utility model the noise of its generation is reduced again because of the rotary speed reduction of nylon rope.The utility model is simple in structure, dependable performance.
