Abstract

本实用新型涉及一种带有多组霍尔传感器电机的变速箱,该变速箱有一个外壳,外壳内从左到右依次设有输出轴、过桥轮轴及电机传动轴,电机传动轴从外壳侧面伸出与电机相连接,在电机内的绕线槽中嵌放有二至四组霍尔传感器;电机传动轴上键滑动连接有高速传动轮和低速传动轮,高速传动轮和低速传动轮之间设有拨叉,拨叉的一端固定有拨杆,过桥轮轴上设有上过桥轮和下过桥轮,上过桥轮与低速传动轮啮合传动,下过桥轮与高速传动轮啮合传动,输出轴上固定有可以与上过桥轮及下过桥轮啮合传动的输出轴齿轮,输出轴的一端伸出变速箱的外壳与传动机构相连。该变速箱不仅结果简单,操作方便,而且可以很容易的改变电机转速,有效节约了工业生产的成本。
Provided is a gearbox with multi-set hall sensor motors, comprising a housing, wherein the housing is internally and sequentially provided with an output shaft, a gap bridge wheel shaft, and a motor transmission shaft from left to right; the motor transmission shaft sticks out from the side surface of the housing to be connected with a motor, with a winding groove of the motor being embedded with two to four sets of hall sensors; the upper key of the motor transmission shaft is connected with a high speed drive wheel and a low speed drive wheel in a sliding manner; a shift fork is arranged between the high speed drive wheel and the low speed drive wheel, with one end of the shift fork being fixed with a driving lever; the gap bridge wheel shaft is provided with an upper gas bridge wheel and a lower gap bridge wheel, with the upper gap bridge wheel being engaged with the low speed drive wheel for transmission while the lower gap bridge wheel being engaged with the high speed drive wheel for transmission; and the output shaft is fixedly provided with an output shaft gear capable of being engaged with the upper gap bridge wheel and the lower gap bridge wheel for transmission, with one end of the output shaft sticking out the housing of the gearbox to be connected with a transmission mechanism. The gearbox features simple structure, convenient operation, and easy motor-speed adjustment, and effectively decreases the cost of industrial production.
