Embodiment Construction
[0021] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0022] Such as Figures 1 to 6 As shown, the flanging thrust bush includes an arc-shaped flat tile 2 and two arc-shaped thrust pieces 1, the radian of the flat tile 2 should be adapted to that of the thrust piece 1, and the two ends of the flat tile 2 There are several gaps 21, and the thrust piece 1 is provided with several protrusions 11, and the two thrust pieces 1 are respectively located at both ends of the flat tile 2, and the protrusions 11 on the thrust piece 1 are embedded in the gaps on the flat tile 2 21, the two thrust plates 1 and the flat tile 2 are welded as a whole, and there is a certain distance between the two thrust plates 1, which should be equal to the width requirement of the flanging thrust bearing bush flanging inner file.
[0023] When processing the flanging thrust bearing bush, first process the arc-shaped flat ti...

The invention discloses a laser welding flanging thrust bearing shell, which comprises an arc-shaped flat shell and two arc-shaped thrust plates, wherein the radian of the arc-shaped flat shell should be matched with the radian of the arc-shaped thrust plates, the two arc-shaped thrust plates are respectively welded on the two ends of the arc-shaped flat shell through laser, and the two arc-shaped thrust plates are separated for a certain distance. The laser welding flanging thrust bearing shell is formed by welding the flat shell and the two arc-shaped thrust plates in a combined mode, and can be produced just by processing the arc-shaped flat shell and arc-shaped thrust plate components firstly and then welding the arc-shaped flat shell and the two arc-shaped thrust plates through laser during the production process, the processing technology of the arc-shaped flat shell and the two arc-shaped thrust plates becomes extremely easy relative to the processing technology of an integrated type flanging thrust bearing shell, the welding between the arc-shaped flat shell and the two arc-shaped thrust plates also is extremely convenient, therefore, the combined type flanging thrust bearing shell is extremely simple in process steps, smaller in difficulty of the processing technology, higher in production efficiency and lower in reject rate, and is extremely suitable for mass production, thereby leading the laser welding flanging thrust bearing shell to be more widely applied.
Description
technical field [0001] The invention relates to a flanging thrust bearing bush, in particular to a combined flanging thrust bearing bush and a processing method of the flanging thrust bearing bush. Background technique [0002] The flanging bearing bush is to flang the two sides of the bearing bush, and use the flanging of the bearing bush as the thrust surface. When this kind of flanging bearing bush is used, the thrust surface needs to be installed between the thrust end surface of the crankshaft of the engine and the plane of the cylinder block. , its function is mainly to withstand the axial thrust caused by the clutch, and to position the crankshaft axially; at the same time, the thrust surface can also ensure a certain axial clearance between the crankshaft and the cylinder, thereby limiting the axial displacement of the crankshaft. The amount of movement. [0003] At present, the structural form of the flanging bearing is mainly the integral structure. There are two ...
