Abstract
The utility model relates to a pin-type slewing bearing which comprises an outer gear ring, an inner ring and a steel ball, wherein the steel ball is positioned in a roller path between the outer gear ring and the inner ring; the outer gear ring is formed by sticking the end surfaces of two semi-ring-shaped parts together; the inner ring is also formed by sticking the end surfaces of two semi-ring-shaped parts together; the two semi-ring-shaped parts of the outer gear ring are connected into a whole by virtue of an upper connecting plate of the outer gear ring, a lower connecting plate of the outer gear ring, a connecting bolt and a locating taper pin; and the two semi-ring-shaped parts of the inner ring are connected into a whole by virtue of an upper connecting plate of the inner ring, a lower connecting plate of the inner ring, a connecting bolt and a locating taper pin. After being cut, the slewing bearing is fixed by the connecting bolts, the locating taper pins and the connecting plates; and when the slewing bearing is disassembled and assembled for use, the two separated semi-circles of the outer gear ring and the inner ring are conveniently and freely combined with each other, so that the slewing bearing can be replaced and used without disassembling the products of a mainframe, and the problem that the slewing bearing can not be replaced since the products of the one-piece mainframe can not be disassembled can be solved. The pin-type slewing bearing is simple in operation and convenient to use, and can be used for lowering the use cost and greatly improving the product use efficiency.
Description
Technical field
The utility model relates to a kind of that be comprised of outer ring, inner ring and rolling element, Internal and external cycle can realize the integrated type pivoting support that rotates.
Background technique
Common pivoting support is comprised of outer ring, inner ring and rolling element at present, and Internal and external cycle can be realized rotating.This type of pivoting support is the integrated type pivoting support, and for the product of the use pivoting support of integrative-structure, the integrated type pivoting support has limited dismounting and the installation of pivoting support, especially large diameter pivoting support.When product needed is changed pivoting support, the main computer boxes complex structure of integral structure, inconvenience disassembles the replacing pivoting support.
Summary of the invention
In order to overcome known integrated type pivoting support dismounting and inconvenient defective to be installed, the utility model provides a kind of pin-type load pivoting support, this pin-type load pivoting support dismounting and easy for installation.
The technical solution of the utility model is: this pin-type load pivoting support comprises external toothing, inner ring and steel ball, in the raceway of steel ball between external toothing, inner ring, external toothing is fitted by two semi-circular spare end faces and consists of, inner ring is also fitted by two semi-circular spare end faces and consists of, two semi-circular spares of external toothing are connected by external toothing upper junction plate, external toothing lower connecting plate, connecting bolt and locating taper pin, and two semi-circular spares of inner ring are connected by inner ring upper junction plate, inner ring lower connecting plate, connecting bolt and locating taper pin.
Described inner ring upper junction plate, inner ring lower connecting plate, external toothing upper junction plate and external toothing lower connecting plate are circular arc spare, and the center of the inside and outside camber line of each circular arc spare overlaps with the gyration center of pivoting support.
Advantage of the present utility model: use connecting bolt and locating taper pin and connecting plate to fix after the cutting pivoting support, when dismounting and erection use, the two semicircle combined and instants that external toothing and inner ring separate freely, need not to dismantle replacing and the use that main computer boxes can be completed pivoting support, having solved that the integral type main computer boxes can't dismantle is the difficult problem of replaceable pivoting support.Simple to operate, easy to use, reduced user cost, greatly improved the product utilization efficiency.

Embodiment
In Fig. 1, Fig. 2 and Fig. 3, this pin-type load pivoting support comprises external toothing 1, inner ring 4 and steel ball 8.In the raceway of steel ball 8 between external toothing 1, inner ring 4.External toothing 1 is fitted by two semi-circular spare end faces and consists of, and inner ring 4 is also fitted by two semi-circular spare end faces and consists of.Two semi-circular spares of external toothing 1 are connected by external toothing upper junction plate 6, external toothing lower connecting plate 10, connecting bolt 2 and locating taper pin 11.Two semi-circular spares of inner ring 4 are connected by inner ring upper junction plate 5, inner ring lower connecting plate 9, connecting bolt 2 and locating taper pin 11.
External toothing 1 and inner ring 4 all arrange mounting hole at circumference uniform distribution, and the X-X line is pivoting support cutting center line, and the otch of external toothing is at the tooth root place, and the otch of inner ring 4 is being avoided the X-X linear position of mounting hole.In addition, inner ring upper junction plate 5, inner ring lower connecting plate 9, external toothing upper junction plate 6 and external toothing lower connecting plate 10 are circular arc spare, and the center of the inside and outside camber line of each circular arc spare overlaps with the gyration center of pivoting support.
External toothing upper junction plate 6 is placed on the reference level of external toothing 1, and external toothing lower connecting plate 10 is placed on the non-reference level of external toothing 1 place.External toothing upper junction plate 6 and external toothing lower connecting plate 10 are provided with and the external toothing 1 mounting hole identical hole that distributes, and are used for installing connecting bolt 2.Simultaneously, external toothing upper junction plate 6 and external toothing lower connecting plate 10 are provided with locating taper pin 11, external toothing upper junction plate 6, external toothing lower connecting plate 10, connecting bolt 2 and the common fixedly external toothing cutting surface of locating taper pin 11.
Same, inner ring upper junction plate 5 is placed on the non-reference level of inner ring 4, and inner ring lower connecting plate 9 is placed on the reference level place of inner ring 4, and inner ring upper junction plate 5 and inner ring lower connecting plate 9 are provided with and the inner ring 4 mounting holes identical hole that distributes, and are used for installing connecting bolt 2.Simultaneously, inner ring upper junction plate 5 and inner ring lower connecting plate 9 are provided with locating taper pin 11, inner ring upper junction plate 5, inner ring lower connecting plate 9, connecting bolt 2 and the common fixedly inner ring cutting surface of locating taper pin 11.
