Description

Integrated seal formula bearing arrangement
Technical field
The present invention relates to bearing arrangements, and in particular to integrated seal formula bearing arrangement.
Background technique
Oil sealing and bearing are the key components and parts as transmission parts such as the engine of automobile and speed changers, and oil sealing will usually move Power part case outside air and internal lubrication oil are kept apart, and power transmitter's axis class of power part enclosure interior rotates Part often requires to use bearing to be supported.Power input, output end need bearing to come support shaft class revolving part, axis class Revolving part stretches out outside shell, it is necessary to which oil sealing will keep apart inside and outside shell, and oil sealing mainly plays the work of seal casinghousing interior media With.What design, processing and the assembly of common oil sealing and bearing were separate from, oil sealing and bearing need connector that will assemble On a shell, separately fabricated oil sealing and bearing higher cost, and due to not becoming one, the axial space of arrangement compared with Greatly, oil sealing and bearing fit, the confronting coaxial degree of the outer ring of oil sealing ontology and bearing reduces between the two, it is ensured that preferably coaxial Degree is so that technology difficulty is big and processing cost is high.
Summary of the invention
Integrated seal formula bearing arrangement disclosed by the invention, solution bearing space is compact-sized, at low cost, sealing performance mentions The problem of rising.
Integrated seal formula bearing arrangement disclosed by the invention, including oil sealing ontology and bearing；The bearing from outside to inside according to Secondary includes outer ring, rolling element and inner ring；The inner ring inner cavity is used to pass through axis class revolving part；The outer ring axially extends in parallel super It crosses inner ring axial length and stretches out stabilizer blade to axis direction in the end of extension；The oil sealing ontology is located in outer ring and and inner ring It is coaxially arranged side by side, inner cavity is used to pass through axis class revolving part；Carrier base is provided on the oil sealing ontology, the stabilizer blade is inlayed In in carrier base；Oil sealing ontology encloses axially inwards stretches out lip, and the lip is for enveloping axis structure.
Further, the lip outer casing spring, the spring radial compaction lip 12.
Further, the outer ring outer surface is equipped with annular groove, and described, the sealing ring is set to the annular groove of outer ring It is interior.
Further, the annular groove is located above inner ring.
Further, the oil sealing ontology and sealing ring are rubber parts.
Further, the outer ring and inner ring are metalwork.
Further, the sealing ring is in wavy with salient point.
Advantageous effects of the present invention are as follows: the present invention has supporting axis by the way that oil sealing ontology and bearing are integrated in one Class revolving part is difunctional with sealing, while oil sealing ontology and the integrated design of bearing can reduce connection between the two Part, axial space is short, structure is compact is able to satisfy more space layouts.The outer ring upper support leg of bearing is directly embedded in oil sealing Oil sealing ontology in, reduced the skeleton of support oil sealing ontology, and oil sealing ontology and bearing are directly connected to reduce between the two Connector, oil sealing ontology is easily guaranteed that relative to the outer ring coaxial accuracy of bearing, be effectively reduced technology difficulty and reduce at This.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
It elaborates with reference to the accompanying drawing to the preferred embodiment of the present invention.
Integrated seal formula bearing arrangement, including oil sealing ontology and bearing.Bearing successively includes outer ring 4, rolls from outside to inside Body 5 and inner ring 6.6 inner cavity of inner ring can pass through axis class revolving part.Rolling element 5, which is set between outer ring 4 and inner ring 6, to be reduced outside The frictional force of circle 4 and the opposite sliding of inner ring 6, inner ring 6, which is located on the inside of rolling element 5, plays supporting axis class revolving part, and outer ring 4 is located at The outside of rolling element 5, which is served, to be supported and fixed.Outer ring 4 is axial to be extended in parallel more than inner ring axial length and in the end of extension Stabilizer blade 41 is stretched out to axis direction.Oil sealing ontology 1 is located in outer ring 4, is coaxially arranged side by side with inner ring 6,1 inner cavity of oil sealing ontology Pass through axis class revolving part.Carrier base 13 is provided on oil sealing ontology 1, stabilizer blade 41 is embedded in carrier base 13.Oil sealing ontology 1 is axial Lip 12 is stretched out to inner ring 6, lip 12 envelopes axis class revolving part.12 outer casing spring 2 of lip, 2 radial compaction lip 12 of spring It provides enclasping force the lip 12 of oil sealing is pressed on axis class revolving part.
4 outer surface of outer ring is equipped with annular groove 42, and annular groove 42 is located at 6 top of inner ring, and a sealing ring 3 is set to outer ring 4 Annular groove 42 in.Sealing ring 3 is in wavy with salient point 31.Continuously convex point realizes multi-layer sealed, wave to salient point 31 The protrusion part of shape, which can be effectively compressed in the space of wavy recess when being installed on shell, reduces assembly resistance Power improves assembling capacity energy, and sealing ring 3 is not easy to be damaged, and its sealing effect is good.
Oil sealing ontology 1 and sealing ring 3 are rubber parts, can effectively play sealing function.Outer ring 4 and inner ring 6 are metalwork, The effect of revolving part can effectively be supported.
