Abstract
The utility model relates to an integral flyer double-groove ball bearing, which comprises a bearing outer ring, a double-groove bearing inner ring, steel ball rolling bodies, holding frames and sealing rings. Two grooves are arranged on the inner wall of the bearing outer ring, the double-groove bearing inner ring is positioned in the bearing outer ring, another two grooves are also arranged on the double-groove bearing inner ring, the grooves on the double-groove bearing inner ring are respectively corresponding to the grooves on the bearing outer ring, a plurality of steel ball rolling bodies are clipped between the groove surfaces encircled by the grooves, and the steel ball rolling bodies are separated through the holding frames at intervals. The sealing rings are respectively arranged at the two ends of the bearing and below the upper grooves, to prevent the grease on the grooves from flowing out. Grease playing the lubrication function is arranged on the surfaces of the grooves and the steel ball rolling bodies. The bearing seat of the ball bearing is processed into the double-groove bearing outer ring, the inner ring is processed into the double grooves, thus the double deep groove ball bearing is formed, the external shape and size of which are consistent with the original shape and size. The integral flyer double-groove ball bearing has the advantages that in the identical operating mode, the noise is obviously reduced, the start can be flexible, the matching error is reduced, the disassembly and the installation are convenient, and the service life of the bearing can be prolonged.
Description
Technical field
The utility model relates to a kind of bearing, belongs to technical field of rolling bearings, the two ditch ball bearings of particularly a kind of whole flier.
Background technique
Selected two cover deep groove ball bearings on the flier for use in the past, be pressed into the bearing support two ends, by the axle sleeve liner of similar bearing ringlet size between the bearing, have the root axial compression to go in bearing inner race and the axle sleeve during work on the flier, this design requires very high to fitting surface, is difficult to during as installed accomplish that two cover bearings are concentric, cause bearing to bear the torsion of decentraction in the running thus, noise occurs and become big, bearing life shortens, so need to improve.
The model utility content
The purpose of this utility model is to disclose that a kind of noise is little, starting flexibly, mismatch error is little, the two ditch ball bearings of the whole flier of bearing long service life.
For reaching the foregoing invention purpose, the technological scheme that is adopted is: the two ditch ball bearings of a kind of whole flier, mainly comprise bearing outer ring, two ditch bearing inner race, steel ball rolling element and retainer and seal ring, bearing outer ring inwall two ends are provided with two raceway grooves, two ditch bearing inner races place in the bearing outer ring, raceway groove on two ditch bearing inner races is corresponding with the raceway groove on the bearing outer ring respectively, several steel ball rolling elements are held between the raceway groove face that raceway groove surrounds, and are opened by the retainer equidistant separation between the steel ball rolling element.Be provided with seal ring between bearing two ends and two raceway grooves.There is the grease of lubricate on the surface of raceway groove and steel ball rolling element.
The two ditch ball bearings of whole flier of the present utility model are processed into the double-groove bearing outer ring with bearing support, and inner ring is processed into double channel, form the double channel deep groove ball bearing, external shape size and being consistent originally.Same operating mode, noise obviously reduces, and starting has reduced mismatch error flexibly, is convenient to remove and install, and has prolonged the working life of bearing, is a kind of very practical design.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1-bearing outer ring, the two ditch bearing inner races of 2-, 3-raceway groove, 4-steel ball rolling element, 5-seal ring, 6-retainer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, the two ditch ball bearings of a kind of whole flier, mainly comprise bearing outer ring 1, two ditch bearing inner race 2, steel ball rolling element 4 and retainer 6 and seal ring 5, bearing outer ring 1 inwall two ends are provided with two raceway grooves 3, two ditch bearing inner races 2 place in the bearing outer ring 1 jointly, raceway groove 3 on two ditch bearing inner races 2 is corresponding with the raceway groove 3 on the bearing outer ring 1 respectively, and several steel ball rolling elements 4 are held between the raceway groove face that raceway groove surrounds, and are opened by retainer 6 equidistant separation between the steel ball rolling element 4.Be provided with seal ring 5 between bearing two ends and two raceway grooves.There is the grease of lubricate on the surface of raceway groove 3 and steel ball rolling element 4.
