Document Type and Number:
WIPO Patent Application WO/2017/024861
Kind Code:
A1
Abstract:
Provided is a sealing structure for a bearing, comprising: a first framework (30) fixed to an outer ring (10) of a bearing, and a second framework (40) fixed to an inner ring (20) of the bearing, and an elastic sealing member. The first framework (30) comprises a first radially extending part (32) extending toward the inner ring (20) of the bearing, and the second framework (40) comprises a second radially extending part (42) extending toward the outer ring (10) of the bearing, wherein the second radially extending part (42) is located at an outer side in an axial direction of the first radially extending part (32). The sealing structure is provided with at least a first chamber (70) and a second chamber (80) in a radial direction. The first chamber (70) is formed solely by the first radially extending part (32) or the second radially extending part (42). The second chamber (80) is located at an inner side in a radial direction of the first chamber (70). The elastic sealing member comprises a first sealing member (50) extending into the first chamber (70), and a second sealing member (60) extending into the second chamber (80). The present invention reduces axial dimensions of a sealing structure by arranging a multilevel seal in a radial direction of a bearing, thereby ensuring an advantageous sealing effect while facilitating an installation of the bearing.
