The invention provides a thrust wheel, a lubricating system and a heading machine. The thrust wheel comprises: a thrust wheel body, wherein the thrust wheel body is provided with a shaft hole, and thethrust wheel body is provided with a sliding groove; a sliding bearing arranged in the sliding groove; and a main shaft penetrating through the shaft hole and suitable for rotating relative to the thrust wheel body, wherein limiting grooves are formed in the two ends of the thrust wheel body and located in the two ends of the sliding bearing, and framework oil seals are arranged in the limiting grooves and are used for preventing lubricating oil in the thrust wheel body from leaking. The framework oil seals are arranged in the limiting grooves, so the thrust wheel prevents leakage of lubricating oil effectively, and also effectively prevents silt, dust, steam and the like c from invading the interior of the thrust wheel body from the outside; and the framework oil seals are convenient tomaintain and good in sealing stability, so it can be guaranteed that the thrust wheel stably operates in severe environments such as silt, the fault occurrence rate is reduced, and the service life ofthe thrust wheel is prolonged.

    本发明提供了一种支重轮、润滑系统和掘进机,其中,支重轮包括:支重轮体,支重轮体设有轴孔,且支重轮体设有滑动槽;滑动轴承,设置在滑动槽内;主轴,穿设于轴孔,并适于相对支重轮体转动;其中,支重轮体的两端设有限位槽,限位槽位于滑动轴承的两端,且限位槽内设有骨架油封,骨架油封用于防止支重轮体内的润滑油泄露。该支重轮,通过将骨架油封设置在限位槽内,有效防止了润滑油的泄露,同时还能有效防止泥沙、灰尘、水气等自外侵入支重轮体内部,且骨架油封便于维护,密封的稳定性较好,能够保证支重轮在泥沙等恶劣环境中稳定运行,减少故障发生率,提高支重轮的使用寿命。
