Abstract
The utility model relates to a water sealing device for oil film bearings, comprising a sealing cover, a foot seal, a sealing hoop, an aluminium ring device, water closing, a water closing chuck ring and round rubber. The utility model is characterized in that: the water closing is tightly pressed on the end face of the sealing cover through bolts and the chuck ring; the water sealing performance is strong; iron scales and water outside the bearings are effectively prevented from entering the bearings; accidents which are caused by water entering bearings and result in the abnormal operation of rolling production lines are avoided; the service life of the oil film bearings is improved. The water closing with the same specification can be used in sealing devices for oil film bearings with various specifications, reducing production cost. The utility model can be widely applied to oil film bearings of various rolling mills.
Description
One, technical field
The utility model belongs to sealing technique, relates generally to the seal arrangement of milling equipment rolling oil film bearing.
Two, background technique
The seal arrangement that existing filmatic bearing uses mainly is made up of sealing cover, aluminum ring device, foot-shape sealing, sealing hoop, water seal etc.Adorn round rubber on the sealing cover, be installed on the bearing support end face by screw, foot-shape sealing is installed on the sealing surface, and sealing hoop is packed in the foot-shape sealing, aluminum ring device is embedded in the water sealing limb side of foot-shape sealing, and water seal is tightened on the sealing cover end face with limited several brass screws.They and bearing support, tapered sleeve, lining, roller set lump together the effect of playing the oil sealing water shutoff.Its shortcoming is: in actual use, after water seal is installed on the sealing cover end face, the S shape appears in the water seal surface, reason is that water seal is a rubber body, only depend on limited several brass screws fastening, be difficult to reach between it and the sealing cover and closely cooperate, will occur uneven, form big gap, make the water, impurity, iron scale etc. of bearing outside be easy to enter bearing inside, the lighter causes deterioration of lubricant, aging, reduces bearing working life, the major accident that also will cause whole rolling line to stop production under the serious situation causes bigger economic loss.
Three, summary of the invention
The utility model is to carry out improved at the structure of above-mentioned existing film bearing seal device, for more effectively stoping outside water, impurity, iron scale etc. to enter filmatic bearing inside, and provide a kind of film bearing seal device that improves sealability and working life.
The filmatic bearing of a kind of seal arrangement that the utility model provides, it has uses bolt to be installed in sealing cover on the bearing support, round rubber between bearing support and sealing cover, the foot-shape sealing of between sealing cover, tapered sleeve, lining and roller neck, adorning, the sealing hoop of installing on the foot-shape sealing, on the sealing cover end face and be embedded in water seal in the seal groove; The aluminum ring device that forms the labyrinth water seal also is housed in the cavity between sealing cover, foot-shape sealing, roll and water seal arrangement; It is characterized in that described water seal also has pressure ring and hold-down bolt, bolt passes pressure ring and is connected with sealing cover, and compresses water seal on the sealing cover end face.
Sealing cover is installed on the bearing support end face in the utility model seal arrangement, foot-shape sealing is inserted on the sealing surface of sealing cover after installing sealing hoop earlier, aluminum ring device is embedded the water sealing limb side of foot-shape sealing, on the sealing cover end face seal groove is arranged, water seal embeds in the seal groove, on sealing cover, pressure ring tightly is pressed in water seal on the sealing cover end face water seal pressure ring with screw-driving.This seal arrangement and bearing support, tapered sleeve, lining, roll are formed closed oil pocket, stop the oil of bearing inside to leak on the one hand, water, impurity, iron scale that stops the bearing outside on the other hand etc. enters bearing inside, has played the effect of oil sealing water shutoff, impurity, iron scale etc. effectively.Water seal tightly is pressed on the sealing cover end face by pressure ring, avoided the water seal surface to occur uneven, eliminated the big gap of formation between water seal and the sealing cover end face, thereby water, impurity, iron scale of making the bearing outside etc. are difficult to enter bearing inside, play the sealing of first road at this, constitute the labyrinth with sealing cover, aluminum ring device simultaneously, stoped entering of cooling liquid and dirt effectively, and the water seal below has water shoot, makes the low amounts of water that enters fully to reflux.And sealing structure for water is more reasonable, can use in the filmatic bearing structure of different size with a kind of water seal.The water sealing limb of foot-shape sealing plays the sealing of second road at this, has further stoped entering of cooling liquid and dirt.The seal oil limb of foot-shape sealing has stoped oily leakage effectively.
By implementing the utility model, provable this seal arrangement can stop cooling liquid and dirt to enter bearing inside effectively, the oil leakage that stops bearing inside effectively, water seal simultaneously can be used in the filmatic bearing structure of different size, has reduced cost of production.The water shutoff of this kind seal arrangement is stronger, has improved defectives such as original structure water inlet, dirt greatly, avoids taking place to cause because of the bearing water inlet accident of whole rolling line cisco unity malfunction, the working life of having improved filmatic bearing.
