Abstract

1295152 Tunnelling machines SMITH INTERNATIONAL INC 23 April 1970 [6 Oct 1969] 19660/70 Heading E1F A tunnelling machine comprises a transmission assembly having a stator releasably coupled at its rearward end to a movable frame, and .having a rotor which is supported by bearings within the stator, which is releasably coupled at its forward end to a rotary cutter, and which is releasably coupled at its rearward end to a drive shaft which terminates to the rear of the assembly. In the machine described, Fig. 1, movable frame 110 is supported for longitudinal sliding movement within support frame 50, and carries drive shaft 130 which rotates cutter 300 via transmission assembly 200. The transmission assembly comprises, Fig. 4, stator 210 attached by bolts 211 to frame 110, and rotor 220 supported by radial bearings 240, 250 within rotor 210, attached by bolts 222 (Fig. 1) to cutter 300, and having a splined coupling 155, 150 with shaft 130. Coupling element 155 is bolted to rotor 220, and coupling element 150 is bolted to shaft 130. Thrust is imparted to rotor 210 by thrust cylinders 80 connected to frame 50 and bearing on stator shoulder 215, and is transmitted to rotor 220 and cutter 300 by thrust bearing 230 located between stator shoulder 217 and rotor shoulder 225. The machine includes a centre drill rotated by shaft 410 via transmission assembly 450 similar to assembly 200. Stator 470 rotates with, and slides longitudinally in rotor 220. Plate springs 504 urge plate 501 into abutment with stator 470, the springs permitting the centre drill to retract under excessive load. Frame 50 is supported in a tunnel by telescopic legs 60, 65. The cutter is advanced by advancing frame 110 within frame 50, extending feet 160, 165 to support frame 110, retracting legs 60, 65, advancing frame 50 along frame 110, extending legs 60, 65 and retracting feet 160, 165.
