This author is about a direct drive motor coupling device, especially a simple structure design, which can effectively reduce the manufacturing cost, and achieve a substantial saving in assembly procedures, reduce the sway during transmission, and can transmit direct drive with large horsepower output. Motor coupling device.

According to the current mechanical power transmission, the indirect transmission of the pulley has been greatly improved to be replaced by a direct drive type. The direct drive motor is assembled between the drive shaft and the mechanical power shaft, mainly by using a coupling device. A joint is made to allow for a deviation from the centerline of both the drive shaft and the mechanical power shaft of the modified direct drive motor.

Please refer to the "Motor Assembly Structure" of China's Announcement No. M408878, the "Modified Structure of the Front Cover of the Motor for Driving the Pump" in China's Announcement No. 498935, and the "Must of the Announcement No. M256387" "The structure of the shaft" and the "pre-assembled structure of the motor" of China's Announcement No. I397623, mainly disclose the structure of the coupling device installed between the drive shaft and the driven shaft of the direct drive motor. The first transmission member and the second transmission member of the device are respectively combined with the direct drive motor by the transmission shaft and the mechanical transmission shaft, and then the engagement end surface of the first transmission member corresponds to the engagement end surface of the second transmission member, and The joint end faces of the first transmission member and the second transmission member are formed with concave and convex protruding teeth and grooves, and rubber joints are formed between the joint end faces of the first transmission member and the second transmission member. The cushion is formed on each of the two ends of the cushion to form a convex tooth and a groove to be respectively engaged with the joint end faces of the first transmission member and the second transmission member. Thereby, when the power transmission operation is to be performed, the direct drive motor is driven to drive the first drive member to be driven by the drive shaft of the direct drive motor, and the first transmission member of the rotation is a cushion formed by the engagement group. The second transmission member is driven to rotate, and the machine connected by the second transmission member is rotated by the transmission shaft to achieve the effect of driving the driven shaft.
