The utility model is specifically a deflection-tolerant structure of a double-wheel milling drive shaft, which comprises a support plate, a cutting wheel, a gear box, a transmission shaft and a driving motor. The cutting wheel is arranged on both sides of the bottom of the support plate, and the gear box is arranged at the bottom of the support plate, and the two ends are connected with the cutting wheels on both sides respectively. The transmission shaft runs vertically through the inner part of the support plate and the lower end of the transmission shaft is inserted into the gear. The box is connected with the transmission gear in the gear box through a bevel tooth; the other end of the transmission shaft is equipped with a drive motor; the transmission shaft is multi-stage, specifically, the transmission shaft is connected by at least three axle bars, and the axle bars of each section are connected by the universal axle of the ball head and the axle base structure. The capacitive offset structure adopts the above design, which makes the traditional one-piece transmission shaft twisted into a spliced transmission shaft with a certain angle by adopting the universal shaft form, so as to solve the problems of reducing transmission efficiency and abnormal noise of gearbox operation caused by the rotation of the transmission shaft axis.

双轮铣传动轴的容偏结构
本技术涉及地下施工设备领域,具体是一种双轮铣传动轴的容偏结构。
技术介绍
双轮铣是地下成槽工艺的常用设备,其大致结构是通过在一块基板的两侧设置从动铣轮并通过一根传动轴从基板中伸出并将动力传递到两侧铣轮的形式实现的,而这一传动形式的问题在于,双轮铣结构复杂、基板乃至铣轮、齿轮箱等各部件自身的加工精度误差、各部件之间的装配误差等往往会使传动轴偏离设计图纸规定的位置,而偏离预定位置的传动轴无意会降低传力效率、影响齿轮箱的正常运作;并最终降低整个双轮铣的使用寿命。
技术实现思路
本技术的目的在于克服上述缺陷,提供一种能够容许传动轴略微偏离设计位置的容偏结构。为了达到上述目的,本技术是这样实现的:一种双轮铣传动轴的容偏结构;其包括支承板、切割轮、齿轮箱、传动轴和驱动马达,其中,切割轮设置在支承板底部两侧,齿轮箱穿设在支承板的底部并且两端分别与两侧的切割轮连接,传动轴竖直贯穿支撑板内部并且传动轴的下端插入到齿轮箱中并通过一个伞齿而与齿轮箱中的传动齿轮连接;传动轴的另一端则设置驱动马达;传动轴是多段式的,具体是指,传动轴由至少三段轴杆相互续接而成,各段轴杆之间均通过球头万向轴及轴座结构而连接。所述的双轮铣传动轴的容偏结构,用于将各段轴杆之间相互续接的球头万向轴及轴座结构可以用摩擦片对拼形式或十字轴对接形式替代。本容偏结构采用上述设计,通过采用万向轴的形式使传统的一体式传动轴变为可扭曲一定角度的拼接式传动轴;如此,在支撑板与齿轮箱各自存在加工误差、装配误差并不可避免的情况下,通过使传动轴发生能够容许一定程度的扭曲来解决因传动轴轴线跳动而导致的传动效率降 ...
