Abstract

The utility model provides a self-aligning roller bearing, belonging to the technical field of machinery; the self-aligning roller bearing solves the problems that the existing self-aligning roller bearing has short service life and low bearing capacity; the self-aligning roller bearing comprises an inner ring and an outer ring; two retaining brackets are arranged between the inner ring and the outer ring, pockets are arranged on each retaining bracket, a roller is arranged in each pocket of the retaining bracket, a limit mechanism which can lead the roller to be limited in the retaining bracket, is arranged between the retaining bracket and the roller, and the outer surface of the outer ring is a spherical surface. The self-aligning roller bearing has the advantages that the structure is simple, the installation is convenient, the cost is low and the bearing has double self-aligning performance.

Description

A kind of selfaligning roller bearing
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of selfaligning roller bearing technical field.
Background technique
Existing selfaligning roller bearing is generally established an annular boss at the internal diameter middle part of retainer, form the Spielpassung face with bearing inner race centre rib position, the rotation of centre rib guiding retainer, when bearing rotates, the annular boss and the bearing inner race centre rib at the internal diameter middle part of retainer have relative movement, easily cause the wearing and tearing of retainer internal diameter, if will improve the bearing capacity of bearing, the length of roller will extend, and this just causes retainer boss width narrow, insufficient strength, become the weak link of bearing, the early stage damage of bearing will be caused if damage in this position, influences the working life of bearing, therefore, the annular boss structure at retainer internal diameter middle part has limited the raising of bearing load carrying capacity, has influenced application area.In addition, existing selfaligning roller bearing, adopt wear resistance good copper product is made more, and the cost of retainer is raised.
Main shaft is bigger mostly at present, and rotating speed is lower, and moment of torsion is big, and amount of deflection is big, and is bad with the existing bearing aligning performance, makes main shaft bearing reduce the working life of also having reduced main shaft simultaneously working life.
Summary of the invention
The purpose of this utility model is the deficiency at existing above-mentioned technology, has proposed a kind of long service life, can dual aligning and the strong selfaligning roller bearing of bearing capacity.
The purpose of this utility model can realize by following technical proposal: a kind of selfaligning roller bearing, comprise inner ring, outer ring, two retainers are housed between inner ring and outer ring, be equipped with the pocket hole on each retainer, it is characterized in that, be equipped with roller in each pocket hole of described retainer, be provided with the position-limit mechanism that roller can be limited in the retainer between retainer and the roller, described outer ring outer surface is a sphere.
Roller is in installation, available beautiful spotflower herb or rod one strike gently, roller can be packed in the retainer pocket hole, and difficult drop-off, depression is arranged on the roller end face, and the retainer two ends are provided with and the corresponding connecting lever of the depression of roller end face, in roller is packed retainer pocket hole into, two ends connecting lever on the retainer embeds respectively in the depression on the with it corresponding roller end face, and roller is positioned.The outer ring outer surface is designed to sphere, so not only can compensate because of machine cut processing or install bad cause initially to neutral error, can also eliminate podiod not being rung that the main shaft amount of deflection brings greatly, have dual aligning performance.
In above-mentioned selfaligning roller bearing, described position-limit mechanism comprises the depression on the roller end face and is arranged on the corresponding connecting lever of depression at two ends and roller end face on the retainer, and the connecting lever on the retainer embeds respectively in the depression on the roller end face of correspondence with it.
The connecting lever at two ends is corresponding settings on depression on the roller end face and the retainer, behind the retainer pocket hole of roller being packed into beautiful spotflower herb or rod, two ends connecting lever on the retainer just embeds the depression on the corresponding with it roller end face respectively, with the roller location, and the roller difficult drop-off.
In above-mentioned selfaligning roller bearing, described bearing inner race is provided with oil groove and oilhole.
Bearing inner race is provided with oil groove and oilhole, so just lubricant oil can be stored in oil groove, and can lubricant oil be incorporated in the bearing by oilhole, improve greasy property, thereby significantly reduced the generation of early failue such as burn, peeling and corrosion phenomena.
Compared with prior art, this selfaligning roller bearing has the following advantages:
1, simple in structure, easy for installation, and can break away from bearing enclose and independently install, promptly one strike gently with beautiful spotflower herb or rod, roller can be packed in the retainer pocket hole, and difficult drop-off.
2, compare with brass solid cage and steel plate pressing cage, it is bigger that it can hold diameter, and length is longer, more aligning roller, thereby can improve the dynamic load rating and the rated static load of bearing, finally reach and improve the bearing effect in working life.
3, the utility model is processed as sphere with the outer surface of the outer ring of existing selfaligning roller bearing, such structure not only can compensate because of machine cut processing or install bad cause initially to neutral error, can also eliminate podiod not being rung that the main shaft amount of deflection brings greatly, have dual aligning performance.

Among the figure, 1, inner ring; 2, outer ring; 3, retainer; 4, roller; 51, connecting lever; 52, depression; 6, outer ring outer surface; 7, oil groove; 8, oilhole.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this selfaligning roller bearing comprises inner ring 1, outer ring 2 and two retainers 3 that are contained between inner ring 1 and the outer ring 2.Each retainer 3 is provided with the pocket hole, roller 4 is housed in the pocket hole, on roller 4 end faces depression 52 is arranged, the two ends of retainer 3 are provided with the depression 52 corresponding connecting levers 51 with roller 4 end faces, behind the retainer 3 pocket holes of roller 4 being packed into beautiful spotflower herb or rod, two ends connecting lever 51 on the retainer 3 just embeds the depression 52 on corresponding with it roller 4 end faces respectively, with roller 4 location, makes roller 4 difficult drop-offs.Outer ring outer surface 6 is a sphere, such structure not only can compensate because of machine cut processing or install bad cause initially to neutral error, can also eliminate podiod not being rung that the main shaft amount of deflection brings greatly, has dual aligning performance, not only reduced the spoilage of main shaft bearing, and improved the working life of main shaft bearing.Inner ring 1 is provided with oil groove 7 and oilhole 8, lubricant oil can be stored in the oil groove 7, and can enter in the bearing by oilhole 8, improve the lubricity of bearing, thereby significantly reduced the generation of early failue such as burn, peeling and corrosion phenomena.
