Slewing rings have a compact design, which facilitates more ease of use and can be manufactured without teeth, with internal or external teeth, with balls and/or with rollers. The patented hourglass design of XZWD slewing ring bearings is especially effective. The design of their slewing rings allows more teeth to be engaged at one time, leading to higher torque endurance and, essentially, a stronger and more durable slewing bearing.
XZWD can design and manufacture the shield tunneling machine main bearing.Normally, the range of slewing bearings used on shield tunneling machine is between 2.5 and 6 meters in outer diameter, such bearings operate in harsh conditions–dirty, corrosive environments with heavy loads and short life expectancy.
XZWD can provide shield tunneling machine slewing ring bearings-engineered to their demanding specifications and delivered on time-is a challenge nearly as big as the bearings themselves. Our experienced engineers specialize in custom designs for hard-rock or soft-rock machines, from main cutter heads and segment erectors to screw conveyors. All designs combine performance and technical efficiency with cost-effectiveness, and are proven with static and dynamic evaluation.
Shield tunnel boring machine, referred to as the shield machine. Special project is a tunnel boring machinery, modern shield tunneling machine set of optical, mechanical, electrical, fluid, sensing, information technology one has cutting soil excavation, transportation of soil ballast assembly Tunnel Lining, measurement-oriented correction and other functions, involving multi-disciplines of geology, civil, mechanical, mechanical, hydraulic, electrical, control, measurement techniques, but also to design and manufacture of "tailored" according to the different geological and reliability requirements. The shield tunneling machine has been widely used in the subway, railway, highway, municipal, hydropower tunnel project.
