Example Embodiment
[0044] Example 1:
[0045] A manufacturing method of a multilayer laminated elastic-plastic alloy self-lubricating bearing includes the following steps:
[0046] 1) A number of axial limit ring grooves and radial limit dovetail grooves are machined on the inner surface of the bearing;
[0047] 2) Sand the inner surface of the bearing to remove oil stains;
[0048] 3) Coat the adhesive CH219 on the inner surface of the bearing with a thickness of 20μm and dry at room temperature, then apply the adhesive CH213 with a thickness of 20μm and dry at room temperature, and then put the adhesive-coated workpiece into the oven Pre-baking at 125℃ for 2.5h to form an adhesive layer;
[0049] 4) Then the elastic cushioning layer (Vulkollan polyurethane elastomer) is centrifuged to coat the adhesive layer, and when the cushioning layer is nearly completely cured, i.e. the cushioning layer is in the drawing state, the bearing layer is centrifuged to coat and solidify; after curing, The thickness of...

[0052] Example 2:
[0053] A manufacturing method of a multilayer laminated elastic-plastic alloy self-lubricating bearing includes the following steps:
[0054] 1) Two axial limit ring grooves and three radial limit dovetail grooves are machined on the inner surface of the bearing;
[0055] 2) Sand the inner surface of the bearing to remove oil stains;
[0056] 3) Coat the adhesive CH219 on the inner surface of the bearing with a thickness of 20μm and dry at room temperature, then apply the adhesive CH213 with a thickness of 20μm and dry at room temperature, and then put the adhesive-coated workpiece into the oven Pre-baking at 125℃ for 2.5h to form an adhesive layer;
[0057] 4) Spread the elastic cushioning layer (CHEMTURA L 100 polyurethane elastomer) on the adhesive layer by centrifugation. When it is nearly fully cured, that is, when the cushioning layer is in the drawing state, then centrifugally coat the bearing layer and cure; after curing , The thickness of the elastic cush...

[0060] Example 3:
[0061] A manufacturing method of a multilayer laminated elastic-plastic alloy self-lubricating bearing includes the following steps:
[0062] 1) A number of axial limit ring grooves and radial limit dovetail grooves are machined on the inner surface of the bearing;
[0063] 2) Sand the inner surface of the bearing to remove oil stains;
[0064] 3) Coat the adhesive CH219 on the inner surface of the bearing with a thickness of 20μm and dry at room temperature, then apply the adhesive CH213 with a thickness of 20μm and dry at room temperature, and then put the adhesive-coated workpiece into the oven Pre-baking at 125℃ for 2.5h to form an adhesive layer;
[0065] 4) Spread the elastic cushion layer (CHEMTURA L 167 polyurethane elastomer) on the adhesive layer by centrifugation. When the cushion layer is almost completely cured, i.e. the cushion layer is in the drawing state, the bearing layer is then centrifuged and cured; after curing , The thickness of the elastic ...
