Abstract
The invention discloses a spliced slewing bearing. The slewing bearing is formed by splicing two semicircular outer rings and two semicircular inner rings which are cut after integrated processing, wherein the two semicircular outer rings are fixedly connected through an outer ring upper connection plate and an outer ring lower connection plate; the two semicircular inner rings are fixedly connected through an inner ring upper connection plate and an inner ring lower connection plate; the two semicircular outer rings and the two semicircular inner rings are respectively fixed through connection positioning pins. The slewing bearing is formed by slicing two semicircles; when a main unit or a usage occasion is strictly limited, an integrated installation space is not provided for the slewing bearing, the integrated safety of the bearing is inopportune or the bearing cannot be integrally installed structurally, the spliced bearing is disassembled and then is assembled, so that all parts of the bearing can be conveniently and freely adjusted, the flexibility is improved, a quick installation requirement is met, the bearing can freely and steadily operate on the main unit, and the defects such as abnormal sound are overcome.
Description
Technical field
The present invention relates to a kind of pivoting support, specifically a kind of spliced pivoting support.
Background technique
Pivoting support is a kind of large size bearing that can bear combined load, can bear simultaneously bigger axially, radial load and tilting moment, in real industry, use very extensive, but some main frame or use occasion restriction are very tight, caused opportunity of the space that do not have the pivoting support integral installation or supporting integral installation not conform to or structure on can't integral installation, the installation situation of standing type for example, main frame is very high, and ground connection, attachment face is determined at medium position, can't sling with crane gear is put on the attachment face, so given the installation of main frame and work zone certain difficulty and danger.
Summary of the invention
In order to address the above problem, the invention provides the high and a kind of novel rotation detachable splicing of supporting in installation and using process the supporting of a kind of flexibility.
In order to achieve the above object, the present invention is achieved by the following technical solutions:
The present invention is a kind of spliced pivoting support, and pivoting support is that two semicircle outer rings and two semicircle inner rings of cutting after the whole processing are spliced by connecting plate again.
Further improvement of the present invention is: fixedly connected with the outer ring lower connecting plate by the outer ring upper junction plate in two semicircle outer rings, and two semicircle inner rings are fixedlyed connected with the inner ring lower connecting plate by the inner ring upper junction plate.
Further improvement of the present invention is: two semicircle outer rings are fixed by being connected locating stud respectively with two semicircle inner rings.
The invention has the beneficial effects as follows: pivoting support of the present invention is by two semicircle splicings, very tight at main frame or use occasion restriction, do not have opportunity of the space of pivoting support integral installation or supporting general safety not conform to or structure on can't integral installation the time, to splice supporting splits earlier, and then assemble, the supporting each several part can make things convenient for adjusting freely, increased flexibility, also satisfy simultaneously the requirement of quick mounting, assurance is bearing on the main frame and goes slick, steadily, defective such as have no abnormal sound.
Pivoting support of the present invention is in the process of using and installing, and the supporting each several part can be adjusted freely easily, and flexibility is strong, is not subjected to environmental limit, and supporting is installed aft engine and gone slick, steadily.
Description of drawings
Fig. 1 is structure sectional view of the present invention.
Fig. 2 is plan view of the present invention.
Wherein: the 1-outer ring, the 2-connecting bolt, 3-outer ring upper junction plate, the 4-inner ring, 5-inner ring upper junction plate, 6-outer ring lower connecting plate, 7-inner ring lower connecting plate, 8-connects locating stud.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with drawings and Examples the present invention is done to describe in further detail, this embodiment only is used for explaining the present invention, protection scope of the present invention is not constituted to limit.
Shown in Fig. 1-2, the present invention is a kind of spliced pivoting support, described pivoting support is that the semicircle inner ring of two semicircle outer rings 1 of cutting again after the whole processing and two 4 is spliced by connecting plate, connect with connecting plate during overall package, can break according to field conditions flexibly or merge assembling, described two semicircle outer rings 1 are fixing by being connected locating stud 8 respectively with two semicircle inner rings 4, make to be formed on the main frame and operate steadily, defective such as have no abnormal sound, fixedly connected with outer ring lower connecting plate 6 by outer ring upper junction plate 3 in described two semicircle outer rings 1, described two semicircle inner rings 4 are fixedlyed connected with inner ring lower connecting plate 7 by inner ring upper junction plate 5.Supporting outer ring is whole processing earlier when producing, so just guaranteed whole precision, then according to design dissect center line cutting, guarantee the technical requirements of section, put the bottom connecting plate well at the lower plane of outer ring, put the top connecting plate well on last plane, connecting plate is evenly pushed down the part bearing ring centered by section, compress back boring, tapping, the bolt of packing into, can connect bearing ring again, according to normal sequence assembling inner ring, the outer ring is assembled in aggregates, pivoting support is transported to the field of employment, take lower connecting plate apart, main frame is loaded onto in butt joint, will go up lower connecting plate again and be fixed in the supporting, assurance is bearing on the main frame and goes slick, steadily, defective such as have no abnormal sound is assembled successfully, during large-scale supporting transportation, the sectional transportation, on-the-spot assembling.
Embodiment: the cement door pillar in the middle of the use of revolving door, revolving door is built up, and the supporting of original structure can't be installed, and uses the spliced swivel bearing of this invention well to solve this problem, and the assembling using effect is good.
