<p>#CMT# #/CMT# The assembly (16) has a rotary member (18) comprising a stationary portion (20) with an electromagnetic coupling unit (26). A disk (22) is mounted on the stationary portion, and has another electromagnetic coupling unit (28) coupled to the former coupling unit. A measurement system measures wear of the rotary member, and has a detecting unit. The detection unit has an electrical circuit arranged in an inner side of the disk. The electrical circuit comprises an electrical wire that cut by abrasion when wear value of the disk is reached, where the wire is connected to the latter coupling unit. #CMT# : #/CMT# An independent claim is also included for a tunneller. #CMT#USE : #/CMT# Electro-mechanical assembly for use in a tunneller (claimed). #CMT#ADVANTAGE : #/CMT# The electrical circuit comprises the electrical wire that cut by abrasion when wear value of the disk is reached, where the wire is connected to the coupling unit, thus ensuring easy, reliable and accurate measurement of the wear of the disk, without the need for complex calculations, and hence reducing maintenance costs of wheels of the tunneller. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of components of an electro-mechanical assembly. 16 : Electro-mechanical assembly 18 : Rotary member 20 : Stationary portion 22 : Disk 26, 28 : Electromagnetic coupling units.</p> |
