Water tank drawbench is a kind of visual plant during the steel cord is produced, and its groundwork principle is by drawing section by section, and the steel wire drawing cone pulley is placed in to the lubricant solution casing that the main component of configuration is pure water, finally steel wire is moved to required specification.My company's T B6 type water tank drawbench has configured 6 cover drawing cone pulleys and has formed 25 passes of drawing.Water tank drawbench drawing cone pulley is placed in the lubricant solution casing, and its main shaft is all to use oil sealing sealing to prevent that lubricant from entering in main shaft bearing.Oil sealing is better to the sealing effectiveness of lubricating oil, and its principle is to intercept oil leak by form oil film at the oil seal lip place, and the lubricant sealing effectiveness that is water to main medium is poor.The lubricant main medium is water, and viscosity is thick not can't form at the oil seal lip place barrier film, and lubricant is bad to the lubricant effect of oil sealing.When lubricant solution is immersed in the cone pulley main shaft through oil sealing, will cause bearing grease inefficacy, bearing corrosion, damage.Use the lathe of FP lubricant, because its solution has higher corrosivity, five, the six axle life-spans of FP lubricant water tank drawbench are normally about 1 month.The fault rate of main shaft is high, has not only increased maintenance cost, to the maintenance personal, brings very large labour intensity, has also greatly affected the production efficiency of lathe.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of raising water tank drawbench Main Shaft Service Life is provided, reduce water tank drawbench main shaft fault, the water tank drawbench spindle machine hermetically-sealed construction of reduce maintenance, safeguarding.
The present invention is achieved by the following technical solution:
Water tank drawbench spindle machine hermetically-sealed construction, comprise main shaft and mechanical sealing assembly, described main shaft is arranged on spindle drum by bearing, described mechanical sealing assembly is arranged in mechanical sealing base, described spindle drum is fixedly connected with mechanical sealing base, also be set with cone pulley on described main shaft, described cone pulley and main shaft are interference fits, and fastening by cone pulley cap.
Described cone pulley cap are tapped hollow arbor braid cap nuts, are provided with the external screw thread be complementary with cone pulley cap on described main shaft.
Described mechanical sealing assembly comprises rotary body axle sleeve, stationary ring, rotating ring, L-type rubber gasket, stage clip, described rotary body axle sleeve is sleeved on main shaft, described stationary ring is fixed on mechanical sealing base, and described moving ring sleeve is contained on the rotary body axle sleeve and keeps laminating with stationary ring under the stage clip thrust.
Described main shaft is provided with groove, is provided with the O RunddichtringO in groove, between rotary body axle sleeve and main shaft, by the O RunddichtringO, seals.
The round nut that also has been threaded on described main shaft, described round nut is arranged between rotary body axle sleeve and cone pulley.
The present invention compared with prior art has following beneficial effect:
Utilize the mode of mechanical seal to substitute the sealing means of oil sealing+axle sleeve, the good sealing effect of mechanical seal to water, the main shaft higher for rotating speed also can guarantee its sealing effectiveness, the water tank drawbench speed of production is normally 17 meter per seconds, adopt the form of mechanical seal can meet the main shaft seal requirement fully, reduce the phenomenon that causes bearing corrosion to damage because of seal failure.Improved the sealing of main shaft, the life-span that the water tank main shaft uses extends greatly, has both alleviated maintenance personal's maintenance workload, has saved maintenance cost, has improved again lathe production efficiency.
