Leaf spring pressing plate unit of double-shaft integral leaf spring structure

Abstract

The invention relates to the field of leaf spring pressing plates, in particular to a leaf spring pressing plate unit of a double-shaft integral leaf spring structure. A boss is arranged on the outer surface of a pressing plate, and a circular hole is formed in the center of the boss, so that the leaf spring plate is fixed; a bearing outer ring is fixed through a bearing fixing groove formed in the lower side of the pressing plate; a bearing is fixed through a bearing clamping groove formed in the inner surface of the bearing fixing groove; a barb is arranged at the end of the bearing clamping groove for hanging, so that the bearing outer ring is effectively reinforced and fixed; an inclined piece circular groove is formed in the lower surface of the inclined piece body and is movably connected with an air rod to conduct effective pneumatic buffering, so that impact loads are effectively absorbed; and buffering can be effectively conducted through an elastic rubber pad arranged on the front surface of an air rod fixing table.

Description

technical field [0001] The invention relates to the field of a spring leaf pressing plate, in particular to a spring leaf pressing plate unit with a biaxial integral spring leaf structure. Background technique [0002] The leaf spring pressing unit should be used in conjunction with the outer ring of the bearing during use, but the existing spring leaf pressing unit with a biaxial integral spring structure has some shortcomings in the process of use and needs to be improved. The shortcomings are as follows : [0003] The first is that the existing spring plate is not firmly fixed and easy to fall off during the process of connecting and matching with the outer ring of the bearing, and the second is that the spring plate unit will be subject to a large impact load during use. The stress concentration of the lower bearing outer ring on the pressure plate unit causes the bearing outer ring to be broken, thereby reducing the service life of the product.
