Abstract
The invention relates to a comb teeth bearing-engagement rolling bearing, which is an engagement rolling bearing which can be freely assembled and disassembled on a crankshaft neck and a connection rod. Before assembling, the inner ring and the outer ring of the bearing are composed of two independent sheets of annular bearings larger than semicircles. A composition interface is a comb teeth engagement port. The bearing has stopping and positioning keys. The inner ring raceway can be manufactured into a smooth finely-grinded raceway and an independent groove-type bead-slot inner ring. The invention is innovative in that a free assembly and disassembly purpose can be achieved; seamless operation of the crankshaft and the connection rod can be satisfied; high-speed and smooth mechanical movement is realized; and defects such as high-speed vibration and reactive power consumption brought by sliding friction are solved.
Description
Technical field
The present invention relates to crankshaft journal, connecting rod can load and unload a watt formula wedging rolling bearing.
Background technique
The equipment of all transformation motion modes such as internal-combustion engine, air compressor is all in conjunction with realizing by bent axle, link assembly.Large and small watt of the bent axle that is commonly called as is one of significant components wherein.
Owing to can't installing with the rolling bearing of full circle on crankshaft journal, just can only adopt the tile of two semicircles to be combined into the sliding bearing member at present.Along with the Technology for Modern Equipment technical requirements is high, need high-speed smooth, Sliding bush obviously can not meet the demands.If the Sliding bush assembly precision is improved, although reduced whirling vibration, running position oil film attenuation watt increases with the friction of crankshaft journal, however caused reactive power consumption and accelerate axle, watt wear away, turn round and got back to again the state of whirling vibration.
Comb structure rolling bearing of the present invention, can be on the large and small neck of bent axle arbitrarily loading and unloading, can satisfy again at a high speed, lowly shake, energy-conservation demand, realize the purpose of seamless running.
Summary of the invention
The present invention relates to crankshaft journal, connecting rod can load and unload the wedging rolling bearing.
According to the present invention: a broach watt wedging rolling bearing comprises inside and outside circle and cylinder ball.The inside and outside circle of fore bearing is installed is respectively two greater than the tile of semicircle, with pressing device, two broach wedge mouth correspondences are pressed in crankshaft journal during installation, be pressed into broach wedge mouth end positioning key, cover tightly bent axle, connecting rod cap, install and finish.
According to the present invention, after the whole circle correct grinding in preassembled inside and outside raceway footpath, the broach raceway can effectively prevent the card bead phenomenon, and the important document that can not occur to wear and tear in advance, cylinder ball passing rate are not affected by this can.
Description of drawings
Proposed especially to think in the present invention the feature of novelty---broach wedging in claims.By with reference to the introduction of following optimization experiment example and by reference to the accompanying drawings, can understand well advantage of the present invention.In the accompanying drawings:
Fig. 1 is bent axle, linkage mechanism Assembly figure, label 1, connecting rod; 2, bent axle; 3, the rolling bearing outer shroud after the combination; 4, cylinder ball; 5, ring in the rolling bearing after the combination; 6, crankshaft counter balance.
Fig. 2 represents combined amplifier sectional view of the present invention, outstanding behaviours oil inlet hole and broach wedging position, inside and outside locking key.
Fig. 3 represents inner groove formula pearl of the present invention position inner ring, and this pearl bit architecture can omit retainer, is also one of a kind of fabrication scheme.
Fig. 4 represents the local amplification view of broach wedge mouth structure of the present invention.
Embodiment
1 to Fig. 4 introduce preferred enforcement of the present invention and just can find out below with reference to the accompanying drawings:
One, its novel feature is that the broach wedging does not exist the card bead phenomenon in raceway.
Two, under existing process conditions, can realize easily work flow and accuracy of manufacturing.
Three, no matter interior ring of the present invention adopts smooth roll road or slot type pearl position raceway can reach technical requirements.
Present embodiment and preferred version are considered to be illustratively and nonrestrictive, the invention is not restricted to described detail in addition, but can modify within the scope of the appended claims.
Claims (5)
1. broach watt wedging rolling bearing, it comprises:
The outer ring: watt form greater than the ring of semicircle by two, two wedging ports that are combined into circle are that broach, stop and positioning key consist of.
Inner ring: watt form greater than the ring of semicircle by two, two wedging ports that are combined into circle are broach, consisted of by oil inlet hole, stop and positioning key, raceway can be the pure annulus surface of correct grinding, making the cylinder pearl circumference around inner ring rolls, also can manufacture each independent slot type pearl position, the independent rotation in the groove position of cylinder pearl.
Cylinder rolling pearl: through the cylinder rolling pearl of correct grinding.
Rolling pearl retainer.
2. the 1 described feature that can arbitrarily load and unload as requested, broach watt wedging port inner and outer rings can cold machinings, and cast form and forge hot are pressed.
3. according to claim 1,2 features, can be applied in the equipment field that comprises all bent axles, bar linkage structure.
4. according to claim 1,2,3 materials for support comprise metal, nonmetal and ceramic.
5. according to claim, the type difference is joined by specification, model, sequence difference, institute.
