The invention discloses a transmission system box body of a crossed double-rotor unmanned helicopter and a transmission system of the crossed double-rotor unmanned helicopter. The transmission systembox body comprises a first casing used for accommodating a straight gear set of the transmission system, a second casing which is used for accommodating a first bevel gear set of the transmission system; two third casings which are used for accommodating two second bevel gear sets of the transmission system respectively; two bearing seats which are arranged at the output end of the third casing ina one-to-one correspondence manner and are used for supporting bearings on an output shaft of the second bevel gear set; a seal for sealing an overhang shaft of the transmission system. The bearingson the output shafts of the straight gear set, the first bevel gear set, the second bevel gear set and the second bevel gear set of the transmission system are installed on the first casing, the second casing, the third casing and the bearing pedestal correspondingly, the transmission system can be effectively protected, the structure is compact, and the weight is reduced; and the structure is simple, the layout is symmetrical, manufacturing and installation are convenient, the manufacturing cost is saved, and the heat dissipation performance and the sealing performance are good.
本发明公开了一种交叉双旋翼无人直升机的传动系统箱体及其传动系统,传动系统箱体包括用于容纳传动系统的直齿轮组的第一机匣;用于容纳传动系统的第一锥齿轮组的第二机匣;用于分别容纳传动系统的两个第二锥齿轮组的两个第三机匣;一一对应地设置在第三机匣输出端的两个轴承座,轴承座用于支撑第二锥齿轮组的输出轴上的轴承;用于密封传动系统的外伸轴的密封件。本申请利用第一机匣、第二机匣、第三机匣和轴承座分别安装传动系统的直齿轮组、第一锥齿轮组、第二锥齿轮组和第二锥齿轮组的输出轴上的轴承,能有效地保护传动系统,结构比较紧凑,减轻了重量;而且结构比较简单,布局对称,方便制造、安装,节省制造成本,散热性和密封性较好。
