Description
Technical field
The utility model belongs to the sliding bearing field, be particularly related to a kind of sliding bearing cross bag of integrated forked crosshead universal coupling, be particularly useful for the cross axle supporting of cross-pin coupling of the transmission of power of the large rolling mill of heavy load, impact load and non-ferrous metal mangler.
Background technique
The main member of universal coupling with spider is comprised of active and passive jaw and cross bag (the cross bag is called again cross assembly), and the middle forced element of transferring power is cross axle.The universal coupling with spider of listing NBS in mainly contains following three kinds: JB/T5513 SWC type integrated forked crosshead universal coupling, JB/T3241 SWP type Split type bearing support universal coupling with spider and JB/T3242 SWZ type solid housing universal coupling with spider.Wherein, cross bag in the SWC type integrated forked crosshead universal coupling adopts non-bolt to connect, Comparision is reliable, therefore use very general, especially obtained being widely used at the metallurgy industry rolling machinery, what this cross bag adopted is the rolling bearing supporting, completely fills short columnar roller combination bearing, needle bearing etc. such as adopting.
Facts have proved, the main failure forms that adopts the universal coupling with spider of rolling bearing supporting be cross axle fracture, cross axle axle journal and plastic indentation appears in surface that the cup endoporus contacts with cylindrical roller or spot corrosion is peeled off.Obviously, this is because the stress that the load that the axle journal of cross axle bears causes has surpassed due to the flexural stress limit and the contact stress limit of material.The generation of these accidents can cause rolling machinery to be shut down suddenly, and the steel rolling production loss is huge, has also increased the maintenance load of rolling machinery.
Also have, the cross bag has adopted full-complement cylinder roller or needle roller supporting, must gappedly could run well between per two adjacent rollers.In cross bag assembly is packed the endoporus process of active and passive jaw of coupling into, in case there is a roller to drop or be shifted from the inside of cup, just need to reload roller, allow the assembler feel very inconvenience.
Have, the cross bag in the existing SWC type integrated forked crosshead universal coupling has adopted exoskeletal radial rubber seal device that rolling bearing is sealed again.Yet, the sealed lip of this exoskeletal radial rubber seal circle will lose sealing effect after wearing and tearing, cause the internal grease of cross bag to run off excessive, extraneous water and steel rolling scale also can enter bearing inside, the fretting wear of ring surface in aggravation roller, axle journal and the cup, the life-span of shortening cross bag.
In addition, cross bag in the existing SWC type integrated forked crosshead universal coupling, main forced element cross axle wherein, when work, to bear the effect of shearing stress, moment of torsion and impulsive load, cross axle usually adopts medium carbon structural alloy steel or low-carbon alloy structural steel such as 20CrMnTi, 40Cr, the materials such as 42CrMo, 20CrMo to make by carburizing heat treatment process, the heat treatment expense is high, its axle journal also requires very high geometric accuracy, dimensional accuracy and good surface roughness value simultaneously, and the manufacture cost of cross axle is high.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of sliding bearing cross bag of integrated forked crosshead universal coupling, it can greatly reduce the contact stress of flexural stress and the journal surface of trunnion journal, can greatly improve lubricated, the sealing effect of cross bag, and easy to loading and unloading, safeguard simply, prolong working life of cross bag.
The technical scheme in the invention for solving the technical problem is: the interference fit positioning ring of packing on the shaft shoulder of cross axle, the metal o-ring of in the groove that positioning ring arranges, packing into, the interference fit axle sleeve of packing on the axle journal of cross axle, axle sleeve outer room unoccupied place rigid bearing bowl, form sliding friction pair between the two, be bolted labyrinth ring on the inner end wall of the cup of close described positioning ring, labyrinth ring and described positioning ring form labyrinth sealing, the axle sleeve exterior edge face mutually is adjacent to the cup interior edge face and contacts, form the axial thrust sliding friction pair, be used for bearing axial force.
1), because sliding bearing has replaced roller or the needle roller of rolling bearing the utlity model has following advantages:, increased the design space of sliding bearing structure, just can increase the axle journal of cross axle and the wall thickness of cup (external diameter that perhaps dwindles cup namely dwindles the diameter of bore of jaw), this has just increased the mechanical strength of jaw.After sliding bearing replaces rolling bearing, thoroughly eliminated the defective that the axle journal, cup endoporus of cross axle and plastic indentation that the roller contact surface occurs or spot corrosion are peeled off, improved the force-bearing situation of cross axle, this has just improved the working life of cross bag, the working life of the coupling that also improves.2), improved the sealing configuration of cross bag, increased greasy property, these measures can prolong the working life of cross bag greatly.3), the utility model is provided with several tapped holes, these tapped holes are the passage that adds grease injection, be again the instrument of dismounting cup, have solved the difficult problem that cross bag for a long time is difficult to dismantle.4) if the sliding friction pair between axle sleeve 2 and the cup 3 damages, as long as change axle sleeve 2 or/and cup 3, and cross axle still can continue to use, this has just thoroughly changed axle journal of existing cross axle in case just the have to situation of scrapping of the defectives such as wearing and tearing, spot corrosion occurs, even defective appears in the cross axle surface, so long as not material crack, all can adopt the method for reparation to recover its geometric accuracy and dimensional accuracy, reach the purpose that reuses, so just greatly reduce user cost.
