The Main Mechanical Processing Equipment Of Tail Shaft Is CNC Lathe Machining Process . The Largest CNC Lathe In Our Company Can Process Large Forged Steel Shafts Up To 12 Meters In Diameter And More Than 2 Meters In Diameter. Of Course, We Also Have Small Lathes That Can Be Mass Produced, Specially For Small Shaft .
High Precision Is An Important Technical Index Of Tail Shaft. Our High Precision Lathe Equipment Can Provide You With Better Service. Generally, The Accuracy Of Giant Shaft Can Reach 0.05 Mm. The Accuracy Of Some Small Shafts Can Reach 0.02mm.
Tail Shaft Of a Large Ship Is Mounted On Two Bearings. One Is Called Tail Bearing, Which Is The Part Of The Ship In Contact With Water; The Other Is Called Front Bearing, Which Is Connected With The Engine Room, While The Front And Rear Bearings Are Basically Closed Between The Tail Cabin.
The Tail Shaft Seal, The Hull Seal Is Achieved By The Sealing Ring Installed Next To The Front And Rear Bearings. The Sealing Ring Is a Closed Rubber Ring, Which Is Sleeved On The Shaft. Generally, The Front And Rear Bearings Have Several Sealing Rings, And The Two Sealing Rings Are Filled With Oil. This Oil Is From a Certain Height Of The Oil Tank, That Is, Gravity Oil Tank, Which Can Balance The Pressure Of Water, And Oil Can Lubricate The Sealing Rings, Reduce The Wear Rate Of Rubber Rings.
In Fact, The Industry Is Called Tail Seal And Front Seal. If The Tail Seal Leaks, The Water Pressure Enters Between The Two Sealing Rings, Which Causes The Oil Level Of Gravity Tank To Rise. The Monitoring And Alarming System Will Alarm, And The Crew Will Know That The Tail Seal Is Out Of Order.
The Front Seal Is Connected With The Engine Room, And There Are Few Water Intake Problems. But If The Front Seal Ring Is Damaged And The Sealing Oil Leaks Out, Causing The Oil Level Of Gravity Tank To Drop, The Monitoring System Alarms, The Crew Will Know That The Front Seal Is Out Of Order.
