本发明为采煤机无链牵引机构,由安装在牵引齿轮架中的牵引齿轮,供牵引齿轮啮合使用的安装在输送机侧板上部的销轴导轨及保证啮合顺利的导向装置组成。这类采煤机滚筒设于两端,由摇臂挚住,其沿工作面牵引则借助牵引齿轮在销轴导轨中的啮合。销轴导轨分段组成,固定在输送机侧板上缘,牵引齿轮就从上方作用在其各个销轴间。为了尽可能摆脱过高和脉动负载的不良影响,这类采煤机都由牵引轮
The invention relates to a chainless traction mechanism of a coal shearer, which comprises a traction gear which is arranged in the traction carrier, a pin shaft guide which is arranged on the upper part of the conveyor side plate and is used for meshing the traction gear, and a guide device which ensures the smooth meshing. Shearer drum at both ends of this type, the rocker Zhichen living, traction along the face is by traction gear in the pin guide rail meshing. Pivot guide rail segments, fixed on the edge of the conveyor side plate, the traction gear on the role of the pin from the above. In order to get rid of the adverse effects of excessive and pulsating load as much as possible, these shearers are driven by traction wheels
