  • Transmission shell, a transmission case and an actuator
    Patent number: 11156289
    Abstract: A transmission shell is applied to an actuator, and an accommodating space for receiving a transmission assembly is formed in the transmission case, the transmission shell is provided with a first ventilation structure, and the first ventilation structure includes a venting hole and a blocking wall disposed around the venting hole; the venting hole is in gas communication with the accommodating space; the blocking wall is disposed on an outer periphery of the venting hole to form a buffering chamber communicating with the venting hole, and an opening is provided at an end away from the venting hole. The present disclosure also provides a transmission case and an actuator using the above transmission shell. The venting hole is effectively waterproof and moisture-proof without requiring a sealing element, and are simple in structure, easy to manufacture, and low in cost.
