Abstract
A kind of long lifetime band bearing pin four-line column roller bearing relates to hydraulic diaphragm pump field of bearings, this bearing comprises outer ring, bearing pin, roller, retainer, dust ring, retainer and plug cock, the external diameter of outer ring is provided with locating slot, the internal diameter of outer ring is ledge structure, outer ring and roller are joined together to form outer assembly by retainer, dust ring and retainer are embedded in the end of outer assembly, be positioned at the stepped locations of outer ring internal diameter, outer assembly and bearing pin form a bearing assembly, bearing pin is provided with lubricating oil path, and plug cock is arranged in bearing pin.Bearing of the present utility model can either well meet radial impact loading demands, the technical problem such as can overcome again bore wear, bearing burnt, the life-span is short, precision is low, reaches more than 80000 hours working life.
Description
Technical field
The utility model relates to band bearing pin four-line column roller bearing of a kind of long lifetime, is mainly used in pump class industry, to be used in hydraulic diaphragm pump connecting rod on connecting rod small end.
Background technique
Hydraulic diaphragm pump bearing former employing cylindrical hole four-line column roller bearing, bears radial impact load.Due to bearing structure feature and usage requirement, cylinder inner ring endoporus and axle adopt interference fit, and the effect of the load that is hit owing to operating for a long time makes inner ring endoporus and axle often occur relative sliding in running, produces crawl, the temperature of bearing is caused to raise, bearing damage.
Model utility content
The bearing bore diameter existed to solve prior art is wriggled the technical problems such as wearing and tearing, Bearing Temperature, life-span be short, and the utility model provides the long lifetime four-line column roller bearing of the innovation structure of a kind of long pin shaft replacement inner ring and axle.
The technological scheme that the utility model technical solution problem is taked is as follows:
A kind of long lifetime band bearing pin four-line column roller bearing, it comprises outer ring, bearing pin circle, roller, retainer, dust ring, retainer and plug cock, the external diameter of outer ring is provided with locating slot, the internal diameter of outer ring is ledge structure, and outer ring and roller are joined together to form outer assembly by retainer, and dust ring and retainer are embedded in the end of outer assembly, be positioned at the stepped locations of outer ring internal diameter, outer assembly and bearing pin circle form a bearing assembly, and be provided with lubricating oil path in bearing pin, plug cock is arranged in bearing pin.
The beneficial effects of the utility model are as follows:
1) directly replace inner ring and axle by long pin shaft, be designed to large, the shock proof four-line column roller bearing of a kind of bearing capacity, avoid the cumulative error of two part processing and assembling.
2) comparatively greatly, its pin diameter accounts for more than 60% of bearing sections size, bearing is directly well connected with crosshead, has stronger rigidity simultaneously, can bear larger impact load for bearing outer ring wall thickness and pin diameter difference.
3) bearing pin inside increases lubricating oil path, lubricant oil is transported to Bearing inner, this bearing is well lubricated.
4) bearing outer ring is designed to the integrity innovation structure that has four row raceways, and external diameter increases locating slot, prevents outer assembly axial motion, outer ring internal diameter is designed to ledge structure, be convenient to dust ring and retainer are installed, make Bearing inner keep clean, improve the lubricating condition of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model long lifetime band bearing pin four-line column roller bearing.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
As shown in Figure 1, long lifetime band bearing pin four-line column roller bearing of the present utility model comprises outer ring 1, bearing pin 2, roller 3, retainer 4, dust ring 5, retainer 6 and plug cock 7, the external diameter of outer ring 1 is provided with locating slot 7-1, the internal diameter of outer ring 1 is ledge structure, outer ring 1 and roller 3 are joined together to form outer assembly by retainer 4, dust ring 5 and retainer 6 are embedded in the end of outer assembly, namely the stepped locations of outer ring 1 internal diameter is positioned at, play dustproof effect, outer assembly and bearing pin 2 form a bearing assembly, bearing pin 2 is provided with lubricating oil path, plug cock 7 is arranged in bearing pin 2, prevent lubricant oil from outflowing.
According to the concrete numerical value of radial impact load that bearing bears, through calculating and finite element analysis, the bearing structure that one best can be selected, such as RNQ644-2LSN-ZC/HC bearing outside diameter 350mm, pin diameter 250mm, the long 530mm of bearing pin, roller diameter 34mm, roller length 62mm, often row roller number 21.
Long lifetime band bearing pin four-line column roller bearing of the present utility model, prove through using, can not only well meet radial impact loading demands, and bore wear, bearing burnt can be overcome, the technical problem such as the life-span is short, precision is low, reach more than 80000 hours working life.
