本发明提出了一种电机10。The invention proposes an electric machine 10 .
一种电机10，包括输出轴11，所述输出轴11的径向上开设有第一固定孔A；传动件12，所述传动件12套设于所述输出轴11上，且所述传动件12上设置有贯穿所述传动件12的第二固定孔B，所述第二固定孔B与所述第一固定孔A位置对应；第一固定件13，所述第一固定件13插设于所述第二固定孔B以及所述第一固定孔A中。A motor 10, comprising an output shaft 11, a first fixing hole A is opened in the radial direction of the output shaft 11; a transmission member 12, the transmission member 12 is sleeved on the output shaft 11, and the transmission member 12 is provided with a second fixing hole B that runs through the transmission member 12, and the second fixing hole B corresponds to the position of the first fixing hole A; the first fixing member 13, the first fixing member 13 is inserted into In the second fixing hole B and the first fixing hole A.
对于传统的电机10，其输出轴11直接与执行设备，例如齿轮、带轮、或者链条等连接，通过电机10的输出动力驱动执行设备转动，而对于输入端无法直接与电机10的输出轴11固定连接的，则通过一个连接件，将电机10的输出轴11与执行设备的输入端连接，因此，当驱动执行设备的扭矩很大时，电机10的输出轴11容易折断，使电机10的输出轴11直接折断，或者在长期转动的过程中，电机10的输出轴11与传动件12会因惯性力导致脱落。For the traditional motor 10, its output shaft 11 is directly connected to the execution equipment, such as gears, pulleys, or chains, etc., and the output power of the motor 10 drives the execution equipment to rotate, but the input end cannot be directly connected to the output shaft 11 of the motor 10. If it is fixedly connected, the output shaft 11 of the motor 10 is connected to the input end of the execution device through a connecting piece. Therefore, when the torque for driving the execution device is large, the output shaft 11 of the motor 10 is easily broken, so that the output shaft 11 of the motor 10 is easily broken. The output shaft 11 is directly broken, or the output shaft 11 and the transmission member 12 of the motor 10 will fall off due to inertial force during long-term rotation.
鉴于此，本实施例中，当执行设备需要输出大扭矩的驱动力时，电机10作为驱动件产生的扭矩大多不能直接接入执行设备上，若直接由电机10的输出轴11带动执行设备，电机10在启动瞬间，电机10的输出轴11可能出现超载的危险，因此需要在电机10的输出轴11上设置一个齿轮箱20或者调速装置，如图1至图2所示，齿轮箱20与电机10的输出轴11之间设置有传动件12，且电机10的输出轴11上开设有第一固定孔A，可以理解，第一固定孔A可以是盲孔(例如沉头孔)，也可以是贯穿电机10的输出轴11，同时在传动件12上设置第二固定孔B，传动件12套设于电机10的输出轴11上，且第一固定孔A与第二固定孔B位置对应，第一固定件13插设于第二固定孔B以及第一固定孔A中，将传动件12与电机10的输出轴11固定连接，传动件12可以设置于齿轮箱20的输入端，或者可以与齿轮箱20的输入轴固定连接，通过上述方式，在长期使用中，可以防止传动件12与电机10的输出轴11脱落。In view of this, in this embodiment, when the actuator needs to output a high-torque driving force, most of the torque generated by the motor 10 as a driver cannot be directly connected to the actuator. If the output shaft 11 of the motor 10 directly drives the actuator, At the moment of starting the motor 10, the output shaft 11 of the motor 10 may be in danger of being overloaded, so a gear box 20 or a speed regulating device needs to be arranged on the output shaft 11 of the motor 10, as shown in Figures 1 to 2, the gear box 20 A transmission member 12 is arranged between the output shaft 11 of the motor 10, and a first fixing hole A is provided on the output shaft 11 of the motor 10. It can be understood that the first fixing hole A can be a blind hole (such as a countersunk hole), It can also be through the output shaft 11 of the motor 10. At the same time, a second fixing hole B is provided on the transmission member 12.
