Embodiment Construction

[0018] see figure 1 with figure 2 , respectively show an exploded view and a cross-sectional view of the transmission mechanism of the automatic door opener provided by the embodiment of the present invention. The transmission mechanism of the automatic door opener includes a planetary reducer 2 and a transmission shaft 3 driven by a motor 1 . The motor 1 can be any type of motor capable of forward and reverse rotation. The planetary reducer 2 includes a housing 20 and a planetary gear train installed in the housing 20 . The planetary gear train includes a final planetary carrier 27 for outputting torque. A torque output hole 270 is provided at the center of the final planetary carrier 27 . The first end of the transmission shaft 3 is detachably inserted in the torque output hole 270 and is non-rotatably connected with the torque output hole 270 , so that the final stage planet carrier 27 drives the transmission shaft 3 to rotate together. The second end of the transmissio...

Abstract

An automatic door operator and a drive mechanism thereof are disclosed. The drive mechanism of the automatic door includes a planetary reducer driven by an electric motor, and a drive shaft driven by a planetary reducer. The planetary reducer includes a housing and a planetary gear train mounted in the housing. The planetary gear train includes a final-stage planet carrier configured to output torque, and a center of the final-stage planet carrier is provided with a torque output hole. A first end of the drive shaft is detachably inserted in the torque output hole and is non-rotatably connected to the torque output hole, and a second end of the drive shaft extends out of the housing. The drive mechanism of the automatic door operator is advantageous to the miniaturization design of the automatic door operator.

Description

technical field [0001] The invention relates to an automatic door opener and its transmission mechanism. Background technique [0002] The automatic door opener is widely used in the field of automatic door opening and closing. The automatic door opener includes a rocker connecting shaft for output torque. The rocker connecting shaft is connected to the rocker system located outside the automatic door opener, and the rocker system is connected to the door. When the automatic door opener is working, it can control the connecting shaft of the rocker arm to rotate forward or reversely, so as to control the rocker arm system to drive the door to open and close. [0003] A typical transmission mechanism of an electric-driven automatic door opener includes a planetary reducer driven by a motor and a transmission shaft driven by the planetary reducer. The planetary reducer includes a housing, a planetary gear train installed in the housing, and an output shaft protruding from the ...
