Description
Technical field:
The utility model relates to bearing structure, particularly a kind of sliding bearing that is used for mill, and it can effectively prolong the operating life of bearing; Reduce the apparatus maintenance cost; Maintenance changes the outfit easy and simple to handle, shortens engineering time, and the production operation efficiency that improves mill is had obvious effect.
Background technique:
The work structuring principle of rubber and plastic mill is that parallel to each other and roller low speed rotation in opposite directions carries out the kneading operations to sizing material by a pair of axis.In refining glue operation process, will bear very greatly from the middle part sizing material and outside radial thrust as the roller of main rotation working part, this radial thrust will directly be transmitted and act on the bearing at supporting roller tube two ends.With regard to the working principle of rubber and plastic mill, this direction from the radial thrust of middle part sizing material is a basic fixed.The rubber and plastic mill in course of normal operation, the supporting roller tube two ends bearing bore is the active force that direction is pointed to single and basic fixed.That is to say: stationarity and the monotony that receives force direction be a fundamental characteristics of mill bearing wear just.And existing rubber and plastic mill great majority are to adopt simple whole sliding bearing structure, and it is the solid bearing lining directly to be fixedly installed on the bearing support roller journal is supported.Because mill working environment dust is serious, the sanitary condition extreme difference; The lubricating condition of solid bearing lining is relatively poor; Be difficult to form complete continuous lubricant film at roller journal and sliding bearing stress surface, this will cause the friction factor of bearing sleeve to increase and enhance faster wear.Particularly since sliding bearing receive the force direction fixed single; Make the wearing and tearing of solid bearing lining supporting plane just only occur in a fixing local location of specific stressed sensing; And all the other positions remain intact, and this just makes the higher bearing sleeve material of value and is underutilized.When the concentrated wear of stressed sensing acquires a certain degree, just must in time shut down and change the solid bearing lining; Otherwise bearing sleeve is will be very fast to be occurred local worn outly and the phenomenon of roller journal and bearing support direct friction takes place, and this will cause even more serious device damage accident.This existing just mill is a main cause of frequent shutdown maintenance owing to sliding bearing weak point in working life.And the operation of changing bearing sleeve very bothers again; It must be taken frame apart and unload bearing support; After changing bearing sleeve, with lathe the bearing sleeve endoporus is carried out fine finishing again, could guarantee that concentricity reinstalls use, the maintenance work that changes the outfit is numerous and diverse; It is consuming time to take a lot of work, and requires very high to equipment and operating technology.In sum, this is short, the difficulty that changes the outfit and engineering time is long and lagging material and underuse and cause the inherent defect of the wasting of resources in the whole sliding bearing of existing mill working life of existing for a long time.
The model utility content:
The purpose of the utility model is in order to overcome the inherent defect of existing whole sliding bearing, to propose a kind of sliding bearing that is used for mill.It can make bearing sleeve integral body stressed by turns equably, lagging material can be utilized cmpletely and then can increase the service life effectively.
The purpose of the utility model realizes through following technological scheme:
A kind of sliding bearing that is used for mill that the utility model proposes; It comprises bearing support, end cap and is fitted to the bearing sleeve in the bearing support; Bearing support is provided with oil hole, it is characterized in that: between bearing sleeve and bearing support, be set with pivoted housing, be provided with endless oil groove in the position of the corresponding oil hole of the outer round surface of pivoted housing; In endless oil groove, be provided with one group be communicated with the bearing sleeve inwall wear the pin through hole; Equipped hollow bearing pin in wearing the pin through hole is provided with worm gear arrangement in the outer rounded ends of pivoted housing, and the worm screw that is fitted to end cap is meshed with the worm gear of pivoted housing.Said pivoted housing is that sliding being assigned in the bearing support also can be rotated in bearing support; Bearing sleeve is fitted in the pivoted housing and is connected to by hollow bearing pin the one-piece element that can together rotate along with pivoted housing; The hollow bearing pin that is adopted can make the oiling oil circuit of endless oil groove to bearing sleeve inwall keep unimpeded; Make it form complete continuous oil film, keep good lubricating status at supporting plane.The certain angle of rotary worm periodically in the mill working procedure; The worm gear that worm screw will drive pivoted housing rotates; Can make the bearing sleeve that is fitted in the pivoted housing along with pivoted housing together rotates; Because bearing sleeve can periodically rotate and rotates stressed position successively, can make bearing sleeve integral body balancedly rotate stressed and uniform wear on whole circumference can utilize the bearing sleeve material cmpletely; Can prolong sliding bearing working life effectively more than three times, this all has positive effect to the manufacturing efficiency that reduces fault power time, reduces the device maintenance expense and then improve mill.
The utility model also has following technical characteristics:
Suit setting sleeve on worm shaft, said setting sleeve is fixedly installed in end cap by locating stud.This structural design can prevent effectively that worm screw is subjected to displacement vertically, and worm screw can only be rotated, and can guarantee that worm and gear has good joggleword state.
External conical sleeve is installed on worm shaft, and said external conical sleeve and setting sleeve constitute the cone match structure.This cone match structure makes worm screw can only carry out one-way rotation; When the backward rotation worm screw; To the reaction force of worm screw external conical sleeve is pressed in setting sleeve by the worm gear that is meshed and form braking moment; That is to say that this cone match structure can only make bearing sleeve rotate successively along a direction and rotate stressed position, bearing sleeve is worn and torn on whole circumference evenly, this is to making full use of lagging material and effectively having certain effect the working life of prolongation bearing.
Be fitted with thrust ball bearing in the worm shaft upper end, said thrust ball bearing press-fits the exterior edge face in setting sleeve by round nut, can reduce the surface friction drag that worm screw is rotated effectively, and is more convenient to operate laborsaving.
Outer rounded ends at pivoted housing is provided with an assembly and disassembly screw, when set dismounting screw is particularly conducive to repair and replacement to the disassembling section of pivoted housing.Can the knockout screw of special use be screwed into one group
In the dismounting screw, can be easily pull out pivoted housing in the bearing support and carry out maintenance work.
The material of hollow bearing pin is identical with the material of bearing sleeve, can make hollow bearing pin and bearing sleeve realize wearing and tearing synchronously and replacing synchronously in the course of the work.
The utility model is compared with existing technology and is had following substantive distinguishing features and progress:
The utility model has been initiated the structure of " by the worm drive pivoted housing bearing sleeve can be rotated successively and rotate stressed position "; And drive bearing sleeve by hollow bearing pin and together rotate with pivoted housing; Can guarantee that the oil circuit of oil hole to bearing sleeve inwall is unimpeded and keep good lubricating status; It can wear and tear evenly bearing sleeve on whole circumference, improve the utilization ratio of lagging material and can prolong sliding bearing working life effectively.The utlity model has advantage simple in structure, that manufacturing cost is low, economic and practical is strong, to reduce the device maintenance expense, enhancing productivity has positive effect.
