Linking the moving parts 2, and reaching the power wheel out of the action, supplemented by the f sub-circuit control, the fine control is called the start and stop [new content], but under the transmission mode of the above-mentioned conventional motor, #in the motor, although Borrowing _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The shaft and transmission gear are damaged. 10% motor rotation 2 The type of overload protection is mainly for the motor not to overheat and burn, so that the motor shaft after the power failure can stop rotating immediately. Therefore, the rotation of the motor in the aged part will continue to rotate due to inertia, and will continue to rotate for a while = electricity In the future, the purpose of this creation is to provide a motor over-protection knot 5 M312832 to ensure compliance with the transmission gear and motor shaft. Extending the service life of the motor f is mainly provided on the rotating shaft of the motor - the sleeve seat, the sleeve seat: the sleeve-drive recording, and the elastic force of the "ya element", so that the external resistance is greater than the surface of the elastic element When the power is strong, ride the _ wheel to the idling state, and turn the gear and the motor shaft to n to effectively extend the life of the motor. [Embodiment] 凊 Refer to the second, third, and fourth figures. The motor overload protection structure provided by the county is mainly provided with a shaft sleeve 4 " The sleeve 4 is sleeved with a transmission gear 32, and is composed of a transmission gear 3 2 by an elastic force of an elastic member 5. The improvement is that the sleeve sleeve 4 is sleeved and fixed to the motor 3 The rotating shaft 31 is disposed for a transmission gear 3 2 , and the bridging seat has a 4-seat-like section 4 1 for a screw-like head 4 2 locking 'the other end has a flange 4 3 as a lock The transmission gear 3 2 has a circular shaft hole 3 21 for being sleeved on the sleeve seat 4; the elastic element 5 is a spring, or is a flexible washer 6 (such as the fifth The embodiment shown in the figure is sleeved on the sleeve seat 4 and locked by a nut 4 2, so that the elastic member 5 (6) presses the transmission gear 3 2 tightly, It can be supplemented by a Huashi 3 3 to average its locking force; by the combination of the above components, the sleeve seat 4, the transmission wheel 32, the washer 34, the elastic element 5 (6) and the screw are sequentially arranged during assembly. The cap 42 is inserted into the motor 3 The rotating shaft 31 is end-operated by the nut 42 to press the transmission gear 3 2 to press the transmission gear 3 2, and the transmission gear 3 2 is engaged with a linkage member 7 to be linked when the motor 3 is operated. The sleeve sleeve 4 is sleeved on the sleeve sleeve 4 6
M312832 上之傳動齒輪3 2連動該連動件7，而此咖推動該連動件7 的阻力遠小於彈性元件5 ( 6 )之麵彈力，故連動件7會受 傳動齒輪3 2之運轉而連動；反之若連動件7—端停止運轉 時’轉軸31因慣性作用並沒有馬上停止轉動，此時連動件7 一端之阻力錢大於雜树5之麵彈力，故而該彈性元件 5⑹不再對傳動齒輪3 2繼，迫使其呈一空轉狀離，如 此便可保護傳誠輪3 2及鱗3之熱3 i，械有蘭升 馬達之使用壽命者。 綜上所述，本創作可即時防止傳動齒輪及馬達轉轴不當運 轉，而特具實賤步效益，有效解決習式所存之缺失者。 【圖式簡單說明】 第一圖，係習式馬達作動示意圖。 第二圖，係本創作之立體示意圖。 第二圖，係本創作之立體分解示意圖。 第四圖，係本創作之作動剖面示意圖。 第五圖，係本創作其雜元件之第二實施例讀示意圖。 第六圖’係本創作其彈性元件之第二實施例剖面示意圖。 【主要元件符號說明】 1 · · · ·馬達 1 1 · · ·轉軸 12···傳動齒輪 2····連動件 3 3 · · · ·華司 4·····軸套座 41····螺紋段 4 2 · · ·螺帽 M312832 3····馬達 4 31···轉軸 5 3 2 · · ·傳動齒輪 6 3 21 ··圓形軸孔 7 3 · · ·凸緣 •··•彈性元件 • · · ·彈性華司 連動件The transmission gear 3 2 on the M312832 interlocks the linkage member 7, and the resistance of the coupling member 7 is much smaller than the surface elastic force of the elastic member 5 (6), so the linkage member 7 is interlocked by the operation of the transmission gear 32; On the other hand, if the 7-end of the linkage is stopped, the rotating shaft 31 does not stop rotating immediately due to the inertia. At this time, the resistance of one end of the linking member 7 is greater than the elastic force of the surface of the hybrid tree 5, so the elastic member 5 (6) is no longer facing the transmission gear 3. 2, forcing it to turn away, so that you can protect the heat of the wheel 3 2 and the scale 3 3, the machine has the life of the Lansheng motor. In summary, this creation can immediately prevent the improper transmission of the transmission gear and the motor shaft, and has a practical and effective effect to effectively solve the missing of the practice.
