Description
Technical field
This utility model relates to a kind of double-layer combined cylindrical roller capacity eccentric bearing, belongs to technical field of bearings.
Background technology
Capacity eccentric bearing is the combination bearing of a kind of structure relative complex, and capacity eccentric bearing has the feature such as high bearing capacity, high accuracy. The rated load of bearing, running accuracy and shock resistance can be improved to greatest extent; Capacity eccentric bearing is easy to use, it is not necessary to eccentric shaft can be achieved with eccentric function, reduces the manufacturing cost of eccentric stiffener;
Existing capacity eccentric bearing is mostly taper roller capacity eccentric bearing, and is single layer structure, and such bearing in use exists the problem that transmission accuracy is low, vibration absorption ability is weak, the life-span in service life is short, rated load is little, shock resistance is poor.
Utility model content
The purpose of this utility model is in use to there is the problem that transmission accuracy is low, vibration absorption ability is weak, the life-span in service life is short, rated load is little, shock resistance is poor to solve existing capacity eccentric bearing, and then provides a kind of double-layer combined cylindrical roller capacity eccentric bearing.
The technical solution of the utility model:
A kind of double-layer combined cylindrical roller capacity eccentric bearing includes inner ring, outer ring and eccentric hoop, described inner ring and outer ring share an eccentric hoop, inner ring is socketed on the inner surface of eccentric hoop, described eccentric hoop is provided with ring flange mounting structure, the inner surface of eccentric hoop is provided with raceway, and cylinder rolling element is arranged in raceway, and described outer ring sleeve is connected on the outer surface of eccentric hoop, the cross section of outer ring is " groove " shape, is provided with long cylinder rolling element between outer ring and eccentric hoop.
Preferred: described cylinder rolling element and retainer realize stop by the inner spring back-up ring being arranged on eccentric hoop inner surface.
Preferred: on the medial surface of one end location and installation of described outer ring ring flange mounting structure on eccentric hoop, the other end of outer ring realizes stop by the outer spring back-up ring being arranged on outer ring.
Preferred: the contact position of described outer ring and eccentric hoop 3 is provided with O RunddichtringO.
Preferred: described eccentric hoop is provided with lubrication channel, lubrication channel is set up with the work space of cylinder rolling element and retainer and is connected.
This utility model has the advantages that the double-layer combined cylindrical roller capacity eccentric bearing of one of the present utility model, bearing roller rolling surface element line abandons conventional straight line and arc structure, adopt loaarithmic curve structure, this structure decreases the contact area between rolling element and raceway, add grease content, reduce heat intensification, improve rotary speed and the service life of bearing. This utility model simple in construction, low cost of manufacture, this product have high rotating speed, in high precision, low-temperature-rise, long-life cylinder roller bearing, added value of product is high, remarkable in economical benefits.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of double-layer combined cylindrical roller capacity eccentric bearing;
1-inner ring in figure, 2-outer ring, 3-eccentric hoop, 4-lubrication channel, 5-cylinder rolling element, 6-retainer, 7-inner spring back-up ring, 8-outer spring back-up ring, 9-long cylinder rolling element, 10-O RunddichtringO.
Detailed description of the invention
Detailed description of the invention one: present embodiment is described in conjunction with Fig. 1, the double-layer combined cylindrical roller capacity eccentric bearing of one of present embodiment includes inner ring 1, outer ring 2 and eccentric hoop 3, described inner ring 1 and outer ring 2 share an eccentric hoop 3, inner ring 1 is socketed on the inner surface of eccentric hoop 3, described eccentric hoop 3 is provided with ring flange mounting structure, the inner surface of eccentric hoop 3 is provided with raceway, cylinder rolling element 5 is arranged in raceway, described outer ring 2 is socketed on the outer surface of eccentric hoop 3, the cross section of outer ring 2 is " groove " shape, long cylinder rolling element 9 it is provided with between outer ring 2 and eccentric hoop 3, described cylinder rolling element 5 and retainer 6 realize stop by the inner spring back-up ring 7 being arranged on eccentric hoop 3 inner surface, on the medial surface of one end location and installation of described outer ring 2 ring flange mounting structure on eccentric hoop 3, the other end of outer ring 2 realizes stop by the outer spring back-up ring 8 being arranged on outer ring 2, described outer ring 2 and the contact position of eccentric hoop 3 are provided with O RunddichtringO 10. so arrange, the double-layer combined cylindrical roller capacity eccentric bearing of this structure, this series bearing ring and rolling element all adopt GCr15, thermal treatment quality is on the basis of working standard, adopt 200 DEG C of tempering and conventional stabilized treatment, eliminate residual stress and make retained austenite precipitate out, make bearing ring and rolling element material structure better, size is more stable, there is better impact resistance, this series bearing roller rolling surface element line abandons conventional straight line and arc structure, adopt loaarithmic curve structure, this structure decreases the contact area between rolling element and raceway, add grease content, reduce heat intensification, improve rotary speed and the service life of bearing. this series axis bearing retainer adopts Hpb59-1-GB1530, and this keeper greatly reduces bearing vibration value and level of noise, improves running accuracy and job stability, improves bearing lubrication quality, extends bearing service life.
Detailed description of the invention two: present embodiment is described in conjunction with Fig. 1, the eccentric hoop 3 described in a kind of double-layer combined cylindrical roller capacity eccentric bearing of present embodiment is provided with lubrication channel 4, and lubrication channel 4 is set up with the work space of cylinder rolling element 5 and retainer 6 and connected. So arranging, lubricating oil can pass through in the work space that lubrication channel 4 injects cylinder rolling element 5 and retainer 6, the noise produced when reducing bearing working.
Present embodiment is the exemplary illustration to this patent, does not limit its protection domain, and its local can also be changed by those skilled in the art, as long as no the spirit beyond this patent, all in the protection domain of this patent.
