Abstract
The utility model relates to the field of large-size slewing bearings, in particular to an asymmetrical multi-section bearing with novel structure and technique. The asymmetrical multi-section bearing comprises an inner ring, an outer ring and a rolling body, wherein the rolling body is arranged on a retainer between the inner ring and the outer ring; and the asymmetrical multi-section bearing is characterized in that the inner ring and the outer ring respectively have an asymmetrical dissectioned structure formed by connecting a plurality of sections of arc-shaped plates; the inner ring and the outer ring, which are formed by connecting a plurality of sections of arc-shaped plates, respectively form closed round roller paths; the retainer is arranged between the roller paths; rollers are arranged on the retainer evenly or unevenly; and the rollers drive the retainer to rotate. Compared with the prior art, the asymmetrical multi-section bearing has the benefits of effectively solving the difficulties of relevant procedures of processing, transportation, assembly, maintenance and the like of large-size bearings, and laying the good foundation for the design and manufacture of various large-size machines.
Description
Technical field
The utility model relates to the large-size pivoting support product scope, relates in particular to the asymmetric multi-subdivision bearing of a kind of structure and technology novelty.
Background technique
The large-size pivoting support product is widely used in fields such as wind-power electricity generation, yard craft, mining machinery, military project, along with the raising of technology and the changes in demand in market, demand for large-sized pivoting support product is increasing, in the prior art, large-sized pivoting support mostly is overall structure, when swing diameter surpassed 5 meters, the processing of its blank and finished product and transportation all existed a lot of inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of asymmetric multi-subdivision bearing, and this bearing is convenient to transportation, assembling with the form that the large scale bearing is designed to cut open more, and easy to maintenance.
For achieving the above object, the utility model is achieved through the following technical solutions:
Asymmetric multi-subdivision bearing, comprise inner ring, outer ring, rolling element, rolling element is arranged on the retainer between inner ring, the outer ring, it is characterized in that, the asymmetric subdivision structure that described inner ring, outer ring connect and compose for the multistage arc plate, the inner ring that some arc plates are spliced, outer ring are formed the closed circle raceway respectively, are provided with retainer between the raceway, even or non-homogeneous being arranged on the retainer of roller, rolling element drives retainer and rotates.
Adopt obtuse angle diagonal built Placement between described two adjacent arc plates.
Described retainer adopts the flexible chain plank frame.
Compared with prior art, the beneficial effects of the utility model are: efficiently solve the difficult problem of relevant links such as the processing of large scale bearing, transportation, assembling, maintenance, for the design and the manufacturing of all kinds of big machineries are laid a good foundation.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, Fig. 3, asymmetric multi-subdivision bearing, the retainer that is made of inner ring 1, outer ring 2, rolling element 4, carrier bar 3, chain rivet 6 and bearing pin 7 constitutes, and the rolling element 4 between inner ring 1, the outer ring 2 is realized the rotation of big machinery and the transmission of radial load.See Fig. 3, the subdivision structure that inner ring 1, outer ring 2 connect and compose for multistage arc plate 5 leave the gap of 1.5～0.1mm between two adjacent arc plates, and partition patterns is a non-symmetry structure.Interface line has 6 °～20 ° left and right sides angles with the bearing center line, can guarantee rolling element 4 steadily to roll across interface and not produce to impact and noise, because interface band angle, the asymmetric shape of arc plate and gap are also very favourable to the maintenance of installing, debugging reaches in use.
Adopt obtuse angle diagonal built Placement between two adjacent arc plates 5, be separately fixed at the position that big machinery need rotate.The linkage structure of bearing pin 7 and carrier bar 3 can realize the even distribution of rolling element 4 at circumferencial direction, and the rib of inner ring 1 is done PURE ROLLING at circumferencial direction guiding rolling element 4.
Rolling element 4 rolling surfaces adopt full convexity cydariform roller, can effectively reduce and install and make the end stress concentration phenomenon that the axis deviation that produces causes.
Claims (3)
1. asymmetric multi-subdivision bearing, comprise inner ring, outer ring, rolling element, rolling element is arranged on the retainer between inner ring, the outer ring, it is characterized in that, the asymmetric subdivision structure that described inner ring, outer ring connect and compose for the multistage arc plate, the inner ring that some arc plates are spliced, outer ring are formed the closed circle raceway respectively, are provided with retainer between the raceway, even or non-homogeneous being arranged on the retainer of roller, rolling element drives retainer and rotates.
