用定压液体静压润滑技术,配合机械无级变速机构变速,按最硬的岩石设计最大转矩。用推进液压缸的推力F,形成刀盘的转矩M,按瞬间M的变化改变刀盘的角速度ω,使Mω=N_e,在挖硬岩时通过调节M与ω,可找到最快的掘进速度vmax,是要求的恒功率无级变速,异步电机功率因数可达到1;不用齿轮传动,耐冲击,只要及时地更换或调节刀具,就可挖通隧道。
With constant pressure liquid hydrostatic lubrication technology, with variable speed mechanical gearbox, according to the most hard rock design maximum torque. With the thrust of the promotion of hydraulic cylinder F, the formation of cutter torque M, M according to changes in the moment of the cutter angular velocity ω, Mω = N_e, digging in the hard rock by adjusting the M and ω, to find the fastest heading Speed vmax, is the required constant power continuously variable speed, asynchronous motor power factor can reach 1; no gear, impact resistance, as long as the timely replacement or adjustment of tools, you can dig tunnel.
