Abstract
The utility model discloses a kind of special roller bearing of single cylinder diesel of long service life, comprise: outer ring, inner ring and be arranged on the some cylindrical rollers between outer ring and inner ring by retainer, between described outer ring, cylindrical roller two ends and inner ring, be provided with installation cavity, four angles of described cylindrical roller are provided with chamfering.Advantage is: axial carrying capacity does not decline, radial bearing capacity improves more than 90%, maximum magnitude meets the requirement of actual use, manufacture cost does not increase, and using effect is good, reaches zero failure within the three guarantees phase of national regulation, long service life, as widely used, by the benefit brought to factory, more mainly bring great benefit to society.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to the special roller bearing of a kind of single cylinder diesel.
Background technique
China's horizontal bar diesel engine widely uses bearing at nearly 20 years inside crankshaft two ends and replaces bearing shell to carry out axially and radial support, and the power of single cylinder diesel is also in continuous expansion, cylinder diameter is caused to be all 6314 by bearing used in 100 to 125 scopes, large-diameter uses 6314 bearings, due to the load that the to-and-fro motion of piston is changed, 6314 bearings are caused early to damage, consequent three guarantees problem is a lot, simultaneously, the tank filler sleeve of bearing is all arranged on the inner side of outer ring and inner ring, processing is inconvenient, and lubrication effect is bad.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of single cylinder diesel of long service life special roller bearing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the special roller bearing of single cylinder diesel, comprise: outer ring, inner ring and be arranged on the some cylindrical rollers between outer ring and inner ring by retainer, between described outer ring, cylindrical roller two ends and inner ring, be provided with installation cavity, four angles of described cylindrical roller are provided with chamfering.
The utility model has the advantages that: the special roller bearing of above-mentioned single cylinder diesel, axial carrying capacity does not decline, radial bearing capacity improves more than 90%, and maximum magnitude meets the requirement of actual use, and manufacture cost does not increase, using effect is good, reach zero failure within the three guarantees phase of national regulation, long service life, as widely used, by the benefit brought to factory, more mainly bring great benefit to society.
Accompanying drawing explanation
Fig. 1 is the structural representation of the special roller bearing of the utility model single cylinder diesel.
In figure: 1, outer ring, 2, inner ring, 3, retainer, 4, cylindrical roller, 5, installation cavity, 6, chamfering, 7, oiling gap.
Embodiment
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the special roller bearing of single cylinder diesel, comprise: outer ring 1, inner ring 2 and be arranged on the some cylindrical rollers 4 between outer ring 1 and inner ring 2 by retainer 3, between outer ring, described cylindrical roller 4 two ends 1 and inner ring 2, be provided with installation cavity 5, four angles of described cylindrical roller 4 are provided with chamfering 6.
Use the special roller bearing dress of above-mentioned single cylinder diesel on the rotary shaft, lubricant oil enters chamfering 6 and the oiling gap 7 between outer ring 1 and inner ring 2 surface to the cylindrical roller 4 rotated from installation cavity 5 and lubricates it.
The special roller bearing of above-mentioned single cylinder diesel, remain unchanged at the internal diameter of the basic upper bearing (metal) of 6314 bearings and beam overall, reduce external diameter, assembling and the actual correlated parts that need and then change that uses of such bearing change, and minimum only have a former bearing cap part.The internal structure of bearing changes simultaneously, axial carrying capacity does not decline, radial bearing capacity improves more than 90%, maximum magnitude meets the requirement of actual use, the actual cost manufactured is for professional bearing mnanufacture factory in addition, compares substantially do not increase with original 6314 bearing mnanufacture costs.Reality uses effect very good, reach zero failure within the three guarantees phase of national regulation, and exceed three guarantees after date reach in the double three guarantees time continue keep zero failure, as widely used, by the benefit brought to factory, more mainly bring great benefit to society.
