Description
Technical field
The present invention relates to milling train, particularly the seal arrangement of filmatic bearing of press on roll.
Background technique
At present, a large amount of milling train use filmatic bearing both at home and abroad, and filmatic bearing ride quality directly affects the ride quality of milling train.The working environment very severe of filmatic bearing of press the dirt invasion and attack such as a large amount of oxides, also will stand washing away of a large amount of high-pressure cooling waters in being subject to the operation of rolling.Filmatic bearing roll neck need to seal, the Main Function of sealing comprises two aspects: one, stop cooling water and dirt to invade filmatic bearing, cooling water and dirt will make lubricating condition worsen, directly affecting oil film forms, even damage bearing, also make that emulsification of lubricant is rotten, the lost of life simultaneously, increase and consume; Its two, stop oil leak, befouling environment, reduces the consumption of lubricant oil, saves and produces and maintenance cost.
Current be arranged on sealing device structure between filmatic bearing and roller neck as shown in Figure 1, formed by sealing cover 9, water seal 10, buffering ring 4, the sealing 7 of pin type and sealing hoop 8, be positioned in the space being formed by tapered sleeve 21, lining 22, bearing support 23 and roll 1.Pin type sealing 7 is the spring-rubber assemblying bodys that comprise seal oil limb 71, water sealing limb 72 and throw oily limb 73, wherein seal oil limb 71, water sealing limb 72 are designed to a kind of flexion type lip, words have larger resilience, have effectively stoped the intrusion of oily leakage and cooling water and dirt.Water seal 10 is rubber product, has certain decrement and resilience under free state, and lip shape and the decrement of appropriate design can fully ensure its " tracing ability " to support roll, bring into play good water sealing effect.On the sealing surface that sealing cover 9 contacts with seal oil limb 71, water sealing limb 72, cover high-abrasive material, friction factor is low, and thermal conductivity is good, can extend and seal service time.Buffering ring 4 cooperatively interacts with pin type sealing 7, sealing hoop 8, sealing cover 9 and water seal 10, composition labyrinth sealing.
There is following problem in the current this sealing configuration of seal arrangement being arranged between filmatic bearing and roller neck: in the outer rugged environment that are exposed at the dirt invasion and attack such as high pressure water flushing brush and a large amount of oxides of water seal 10, in rolling process, there is axial float in roll 1, after long-time use of roll end face contacting with water seal 10, wear and tear, cause water sealing limb 101 to lose efficacy, cause the dirt such as cooling water and a large amount of oxides to invade filmatic bearing, lubricating condition in filmatic bearing is worsened, directly affecting oil film forms, even damage bearing, also can make emulsification of lubricant rotten simultaneously, the lost of life, increase and consume.
