Abstract
The invention discloses a sealing assembly for a universal joint for a crossed shaft type universal shaft coupler. The sealing assembly comprises a sealing element and a sealing seat, wherein the outer side of the sealing element is provided with a main sealing lip and a sub sealing lip which are inclined relative to the sealing element, the two sealing lips are respectively inclined in a direction towards the end part of the opening end of a bearing sleeve, the main sealing lip forms an angle being 40 degrees to 50 degrees with the axial direction of the sealing element, the sub sealing lip forms an angle being 25 degrees to 30 degrees with the axial direction of the sealing element, a U-shaped cavity is formed between the main sealing lip and the sub sealing lip, the thickness of the main sealing lip is 0.8 to 1.5mm, the thickness of the sub sealing lip is 80 percent of the thickness of the main sealing lip, the outer side of the sealing seat is provided with an annular groove, the depth of the annular groove is 4 to 4.5mm, the pre-tightening quantity being 0.1 to 0.2mm is realized between the width of the annular groove and the width of the sealing element, and the sealing element is arranged on the sealing seat through the annular groove formed in the sealing seat. The sealing assembly has the advantages that the sufficient lubrication of a sealing lip part can be realized, the abrasion can be reduced, and the in-site construction condition of the universal joint can be met.
