Description
[technical field]
The utility model relates to a kind of retainer, especially relates to a kind of huge revolving bearing segmentation abnormity retainer.
[background technique]
Known, ladle turret is the key equipment of casting machine, and turning round large bearing is the ladle turret core component, the work characteristics of the large bearing of steel ladle rotary table revolution:
(1) heavy duty.The large bearing of ladle turret need carry the load of hundreds of ton to upper kiloton, comprises both sides ladle, molten steel, and the deadweight of support pivoted arm hundreds of ton, and when all support the ladle that fills with molten steel, suffered load was maximum when two pivoted arms.
(2) unbalance loading.The operating mode of the large loading ability of bearing of ladle turret has 5 kinds: namely both sides are fully loaded, and one is full, a full nothing, and an empty nothing, two without two skies.Maximum unbalance loading appears at a side ladle and fills with the operating mode of molten steel opposite side without ladle, and now the large bearing of ladle turret can bear maximum tilting moment.
(3) impact.When laying mobile ladle, produce very large impact, this impact makes the large bearing of traverse platform bear larger impact dynamic load.
(4) high temperature.High-temperature molten steel in ladle can produce thermal radiation to traverse platform, thereby makes the large bearing of ladle turret bear additional thermal stress; The molten steel particle splashed while pouring into a mould in addition brings hidden danger also can for the large bearing of traverse platform.
The rolling element of the large bearing of steel ladle rotary table revolution is cylindrical roller, roller length two ends swing diameter difference of living in the bearing operation process, the linear velocity difference, roller end line speed is large in the outer part, and it is little by inboard roller end line speed, thereby can cause that roller is crooked to skid, surface friction drag is increased, therefore retainer not only plays guiding, the separation roller effect, also must bear in operation process and rolling element and lasso guide surface surface friction drag and Driving force effect, therefore the structure of retainer directly affects usability and the life-span of bearing, if the large bearing generation of traverse platform early failue, will affect the production of whole casting machine production line and output, serious even can cause huge economic loss or casualties.
Common huge revolving bearing adopts the shape pocket hole retainer of taking turns of nylon or casting aluminium material, and in use very easily fracture is lost, and causes the disordered state of roller motion, makes that roller is cracked, the raceway wearing and tearing chew and peel off; Take turns shape pocket hole because Xiao，Dou hole, gap profile female surface is large, so easily pile up foreign material in profile gap, pocket hole, will cause the revolution clamping stagnation, thereby cause the early failue of the large bearing of traverse platform.
[model utility content]
In order to overcome the deficiency in background technique, the utility model discloses a kind of huge revolving bearing segmentation abnormity retainer, the utility model, by adopting straight pocket hole, fillet side, the two-sided aluminum bronze of built-up welding with copper packing leg and external diameter to wear the retainer matrix of logical oil groove design, reaches the purpose that extends the retainer life-span, improves the retainer frictional behaviour with this.
In order to realize described model utility purpose, the utility model adopts following technological scheme:
A kind of huge revolving bearing segmentation abnormity retainer, comprise retainer matrix, copper packing and built-up welding aluminum bronze leg, on the side of retainer matrix, be evenly distributed with a plurality of pockets hole and built-up welding aluminum bronze leg, built-up welding aluminum bronze leg is arranged on the side of the retainer matrix between adjacent two pocket holes, on the outer diametric plane of retainer matrix, is uniformly distributed a plurality of logical oil grooves.
Described a kind of huge revolving bearing segmentation abnormity retainer, described retainer matrix is structure as a whole, and adopts steel plate to be made.
Described a kind of huge revolving bearing segmentation abnormity retainer, described pocket hole is square structure, four jiaos of the pocket hole is fillet structure or oval structure.
Described a kind of huge revolving bearing segmentation abnormity retainer, the upper side of described built-up welding aluminum bronze leg is provided with copper packing, the Placement that is connected employing argon arc weld deposit aluminum bronze of copper packing and built-up welding aluminum bronze leg.
Described a kind of huge revolving bearing segmentation abnormity retainer, described logical oil groove is arcuate structure.
Described a kind of huge revolving bearing segmentation abnormity retainer, described built-up welding aluminum bronze leg are on two sides that symplex structure is arranged on the retainer matrix.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
A kind of huge revolving bearing segmentation abnormity retainer described in the utility model, comprise retainer matrix, copper packing and built-up welding aluminum bronze leg, by adopting straight pocket hole, fillet side, the two-sided aluminum bronze of built-up welding with copper packing leg and external diameter to wear the retainer matrix of logical oil groove design, with this, reach the purpose that extends the retainer life-span, improves the retainer frictional behaviour; The utility model is simple in structure, practical, easy for installation, has effectively solved the retainer life-span short, easily turn round clamping stagnation, and the problem that frictional behaviour is poor has realized the target of floating bearing highi degree of accuracy, high stability, high strength, long lifetime, low friction.
