Description

Long lifetime ball bearing structure
Technical field
The utility model relates to technical field of bearings, particularly relates to long lifetime ball bearing structure.
Background technique
In electro-mechanical arts application widely, be rotationally connected place for various, effectively reduce rotational resistance, deep groove ball bearing is common a kind of ball bearing to bearing.Ball bearing generally comprises bearing inner race, bearing outer ring, ball, retainer, ball bearing is divided into again open, sealed type usually, sealing mechanism is not with in the both sides of open i.e. bearing outer ring, bearing inner race, sealed type refers to and is provided with sealing configuration between bearing inner race, bearing outer ring, plays dust-proof, waterproof, grease proofing effect.But bearing operationally, relatively rotate between bearing inner race and bearing outer ring, common sealing configuration easily weares and teares, thus cause bearing seal hydraulic performance decline, extraneous dust, moisture, greasy dirt easily enter in bearing, ball is caused to wear and tear, bearing inner race is connected with rotating shaft simultaneously, when bearing normally works, the temperature of its inside may reach 40 DEG C-80 DEG C, if sealability reduces, the lubricant oil around ball can vapor away, thus cause ball rolling resistance to increase, reduce the working life of ball bearing.
Chinese patent Authorization Notice No.: CN202468719U, authorized announcement date on October 3rd, 2012, disclose a kind of axial seal bearing being provided with seal ring, in the outer ring of bearing, be provided with inner ring, be provided with steel bead groove at the middle part of bearing enclose, in steel bead groove, be provided with steel ball, steel ball is assembled in steel bead groove by steel ball frame, two outer ends of steel bead groove are provided with seal groove, and seal groove, built with seal ring, is realized sealing by tight cooperation of seal ring with the external diameter outer surface of bearing inner race.Its deficiency is relatively rotating for a long time along with bearing enclose, and seal ring and Internal and external cycle can be worn, thus cause sealability to decline, and reduces bearing working life.
Model utility content
The utility model is short in order to overcome the bearing seal time of the prior art, and dust, moisture, greasy dirt easily enter the deficiency reducing bearing working life in bearing, provide a kind of good sealing effect, the ball bearing structure of long service life.
To achieve these goals, the utility model adopts following technological scheme:
A kind of long lifetime ball bearing structure, comprise bearing inner race, bearing outer ring, ball, retainer, the outside of bearing inner race is provided with interior ball grooves, the inner side of bearing outer ring is provided with outer ball grooves, described ball is positioned at outer ball grooves, between interior ball grooves, external sealed groove is respectively equipped with inside the two ends of described bearing outer ring, interior seal groove is respectively equipped with outside the two ends of described bearing inner race, described bearing inner race, also support ring is provided with between the end of bearing outer ring, the outer ring of described support ring is provided with exterior seal ring, the inner ring of support ring is provided with ring-shaped sealing sleeve, the inner side of described ring-shaped sealing sleeve is provided with the sealing lip coordinated with interior seal groove, the inner side of described external sealed groove is provided with connecting ring, annular space is formed outside connecting ring and between exterior seal ring, some V-arrangement reeds are circumferentially evenly provided with in annular space, described V-arrangement reed is fixedly connected with connecting ring outer side surface, inside the outer end of V-arrangement reed and exterior seal ring, contact free supports.
Exterior seal ring plays seal action to bearing outer ring, owing to being subject to the elastic force effect of V-arrangement reed inside exterior seal ring, good sealing effect on the one hand, the frictional force between exterior seal ring and bearing outer ring is caused to be greater than the frictional force of ring-shaped sealing sleeve and bearing inner race on the other hand, when bearing rotates, can not relatively rotate between exterior seal ring and bearing outer ring, produce relative rotation between ring-shaped sealing sleeve and bearing inner race, exterior seal ring and bearing outer ring remain good seal, and the surface area ratio bearing outer ring sealing surface of bearing inner race sealing surface is much smaller, ring-shaped sealing sleeve and sealing lip seal jointly, good sealing effect, effectively prevent extraneous dust, moisture, greasy dirt enters Bearing inner, improve bearing working life.
As preferably, described interior seal groove has three roads, sealing lip Ye You tri-road that described ring packing puts, and three seals lip stretches into seal groove sealing in three roads respectively.Three seals groove, sealing lip fitted seal, improve sealability.
As preferably, the outer end of described ring-shaped sealing sleeve extends to form auxiliary seal lip, and described auxiliary seal lip and the outer wall elastic fit of described bearing inner race seal.Auxiliary seal lip is less than the external diameter of bearing inner race at its internal diameter of nature, and after therefore installing, the inner ring of auxiliary seal lip and the wall contacts of bearing inner race are Elastic Contact, have the performance of wear compensation.
As preferably, described interior ball grooves, the bottom of outer ball grooves are provided with oil storage tank, are provided with lubricant grease in oil storage tank, and the opening end both sides of described oil storage tank are connected by cambered surface smooth transition with between interior ball grooves, outer ball grooves.Oil storage tank can store more lubricant grease, keeps ball to lubricate for a long time, and when bearing working ambient temperature is higher, lubricant grease is direct after volatilizing to be lubricated ball, and when after surrounding environment cooling, most of lubricant grease can flow in oil storage tank.
As preferably, the bottom of described oil storage tank is provided with heat-resisting sponge.Partial lubrication grease is adsorbed by heat-resisting sponge, and not volatile, loss, extends the RT of lubricant grease, improves the working life of bearing.
Therefore, the utility model has good seal performance, Sealing period is long, the beneficial effect of long service life.
