Tunneling machine main bearing 19″My own tunnel boring machine has to use someone else”s main
bearing” (Science and Technology Daily, June 7)
The main bearing, known as the “heart” of the full-section tunnel boring machine, bears the main load
during the operation of the tunnel boring machine.
It is a key component of the cutterhead drive system and works in very harsh conditions. Compared
with traditional rolling bearings with a diameter of only a few hundred millimeters, the main bearing of a
tunnel boring machine is generally several meters in diameter. It is the most complex bearing and requires
hundreds of manufacturing processes. In terms of the manufacturing capacity of the entire boring machine
, domestic boring machines are close to the world”s most advanced level, but the most critical main bearings
all rely on imports. Germany”s Rothe Ed, IMO, FAG and Sweden”s SKF occupy the market.
