The invention discloses an improved door machine motor belt pulley installation structure and method. The improved door machine motor belt pulley installation structure includes a door machine motor and an improved door machine motor belt pulley; the improved door machine motor belt pulley includes a belt pulley body, an outer pulley plate and an inner pulley plate, wherein the belt pulley body, the outer pulley plate and the inner pulley plate are rigidly connected, and an inner cone hole is formed in the center of the belt pulley body; a bolt through hole is formed in the center of the outerpulley plate; the door machine motor is provided with a solid rotating shaft, the outer peripheral surface of the shaft extension end of the solid rotating shaft is a conical surface adapted to the inner cone hole of the belt pulley body, and a blind threaded hole is formed in the center of the outer end surface of the solid rotating shaft; and during installation, the solid rotating shaft is inserted into the inner cone hole of the belt pulley body, and the conical surface of the solid rotating shaft is matched with the inner cone hole; and a spring washer sleeves a fastening bolt, the fastening bolt penetrates through the bolt through hole and then screwed into the blind threaded hole and fastened. According to the improved door machine motor belt pulley installation structure and method, the conic fitting coaxiality precision is high, the tightness is good, clearance or interference can be adjusted, torque transmission can be carried out by friction, and torque transmission is morestable and reliable.

    本发明公开的改进型门机马达皮带轮安装结构及安装方法,包括门机马达和改进型门机马达皮带轮;改进型门机马达皮带轮包括刚性连接的皮带轮体、外轮板和内轮板,其在皮带轮体内的中心设有内锥孔;在外轮板的中心加工有螺栓通孔;门机马达具有实心转轴,实心转轴的轴伸端外周面为与皮带轮体的内锥孔相适配的圆锥面,在实心转轴的外端面中心加工有一螺纹盲孔;安装时,实心转轴插入到皮带轮体之内锥孔中且实心转轴的圆锥面与内锥孔相配合,用一紧固螺栓套上弹簧垫圈穿过螺栓通孔后旋入螺纹盲孔内并紧固。本发明圆锥配合同轴度精度高,紧密性良好,间隙或过盈可调整,可以利用摩擦力传递转矩,转矩传递更稳定可靠。
