Rotating mechanism device of automatic vertical hinged door
A rotating mechanism device of an automatic door comprises a rotating shaft, a step is arranged in the middle of the rotating shaft, a pressure bearing is connected to the step, the part, above the step, of the rotating shaft is fixedly connected with an upper hinge piece, and the part, below the step, of the rotating shaft penetrates through the pressure bearing and a needle bearing; the needle bearing is located in the sliding groove, the outer wall of the sliding groove is fixedly connected with the lower hinge piece, and the tail end of the sliding groove is fixedly connected with the gear motor through a fixing accessory. The portion, penetrating out of the tail end of the needle bearing, of the rotating shaft is provided with a cavity, the inner wall of the cavity is provided with a plane A, the outer wall of the transmission sleeve is provided with a plane B, the plane A and the plane B are in key fit to transmit torque, a gap is formed between the inner wall of the cavity and the transmission sleeve, the transmission sleeve is provided with a key, the key is matched with a gear motor output shaft, and the gear motor output shaft works in the transmission sleeve. The gap provides an offset space for the rotating shaft, so that the output shaft of the gear motor can be well protected, and the service life of the output shaft of the gear motor is prolonged.
一种自动门的旋转机构装置，包括转轴，转轴的中部位置处设置有台阶，台阶处连接压力轴承，转轴台阶以上的部分固定连接上页片，转轴台阶以下部分从压力轴承和滚针轴承内部穿过，所述压力轴承位于滑槽上部，所述滚针轴承位于滑槽内部，滑槽外壁固定连接下页片，滑槽末端通过固定配件固定连接减速电机；转轴穿出滚针轴承末端部分设置为空腔，空腔内壁上设有平面A，传动套外壁上设有平面B，平面A、平面B键配合传递扭矩，空腔内壁与传动套之间设置有空隙，传动套上设置有键，键配合减速电机输出轴，减速电机输出轴工作在传动套内部，设置空隙给转轴一个偏移的空间，能够很好的保护减速电机输出轴，增加减速电机输出轴的使用寿命。
