Abstract
The utility model relates to a sealing device for a joint of upper and lower inner rings of a slewing bearing, which belongs to a slewing bearing. The sealing device is characterized in that: an annular sealing groove is arranged at the bottom of the upper ring in the slewing bearing, and a sealing ring is arranged in the annular sealing groove and is an O-shaped sealing ring; and then the inner lower ring is arranged, and a connecting bolt is arranged in a connecting hole to fix the inner upper and lower rings. With the sealing device, lubricating grease is effectively prevented from being leaked out of the joint, and the good sealing performance is obtained.
Description
Technical field
The utility model belongs to pivoting support, especially relates to a kind of seal arrangement of pivoting support.
Background technique
Existing pivoting support, especially more and more widely three pieces type pivoting support of Ying Yonging such as three pieces type decussation roller pivoting support, three organ timbering formula pivoting supports and double row reducing ball-type slewing bearing, the circle up and down of its inner ring is fixed together by connecting bolt, but because the distortion that produces in machining error and the course of working, cause the circle up and down of this inner ring not fit together fully, like this with regard to gapped existence, tend to take place the lubricating grease leakage phenomenon, both be unfavorable for clean environment firendly, influenced the competitiveness of product in market again.
Summary of the invention
The purpose of this utility model provides a kind of joining portion of circle up and down seal arrangement of pivoting support inner ring, eliminate the pivoting support inner ring effectively and enclose the phenomenon that lubricating grease is easily leaked at the joining portion up and down, good airproof performance not only, clean environment firendly, and improve the competitiveness of product in market.
The purpose of this utility model is achieved like this: a kind of joining portion of circle up and down seal arrangement of pivoting support inner ring, the outer ring, interior Shang Quan, Nei Xiaquan, connecting bolt and the roller that comprise pivoting support, uniform successively installation roller and spacing block on the ring raceway on earlier in pivoting support outer ring and pivoting support between the circle, the corresponding again Nei Xiaquan that pivoting support is installed, with connecting bolt interior Shang Quan and Nei Xiaquan are fixed at last, pivoting support outer ring and the mutual support of pivoting support inner ring are also relatively rotated, it is characterized in that:
Annular seal groove is offered in the bottom surface of circle in pivoting support, in this annular seal groove, seal ring is installed, the sealing circle can be O-ring seals, enclose down in installing then, connecting bolt is installed in attachment hole again fixes interior Shang Quan and interior circle down, prevent the leakage of lubricant grease effectively, obtain good sealing property from the joining portion.
The joining portion of the circle up and down seal arrangement of the pivoting support inner ring that the utility model proposes, rational in infrastructure, easy to use and reliable, good sealing property is arranged, prevent the leakage of lubricant grease effectively from the joining portion.
Now in conjunction with the accompanying drawings and embodiments the joining portion of the circle up and down seal arrangement of the pivoting support inner ring that the utility model proposed is further described.
Description of drawings
Fig. 1 be the pivoting support inner ring that proposes of the utility model enclose the main schematic representation of looking of partly cuing open of joining portion seal arrangement up and down.
Among Fig. 1: 1, outer ring 2, roller 3, interior circle 4, seal ring 5, connecting bolt 6, the Nei Xiaquan of going up.
Embodiment
As can be seen from Figure 1: a kind of joining portion of circle up and down seal arrangement of pivoting support inner ring, the outer ring 1 that comprises pivoting support, interior circle 3, interior circle 6, connecting bolt 5 and the roller 2 down gone up, uniform successively installation roller 2 and spacing block on the ring raceway on earlier in pivoting support outer ring 1 and pivoting support between the circle 3, the corresponding interior circle 6 down that pivoting support is installed, with connecting bolt 5 interior upward circle 3 and interior circle 6 are down fixed at last, pivoting support outer ring 1 and the mutual support of pivoting support inner ring are also relatively rotated, it is characterized in that:
Annular seal groove is offered in the bottom surface of circle 3 in pivoting support, seal ring 4 is installed in this annular seal groove, sealing circle 4 can be O-ring seals, enclose 6 down in installing then, it is fixing with circle 3 on interior and interior circle 6 down that connecting bolt 5 is installed in attachment hole again, prevent the leakage of lubricant grease effectively, obtain good sealing property from the joining portion.
