Fluidized bed powder coating on the surface of the metal hinge sphere (2). There is a polyamide coating (3) created by the method. Polyamide coating (3), 25 It is based on Polyamide 11 or Polyamide 12. The polyamide material withstands friction. Thanks to its structure that can be used on working surfaces, the surface of the metal hinge sphere (2) instead of direct metal-plastic contact between the POM mattress (4) polyamide-POM A contact surface is created. POM bearing (4), polyamide coated metal hinge ball (2) at least partially 30 will surround and allow the movement of the metal joint sphere (2) inside the joint (1). They are positioned in such a way as to provide contact that works against each other. One of its surfaces is coated with polyamide (3), and the other is a POM mattress (4). is being created. Polyamide coating (3) and POM mattress (4) are made of different polymer materials. This occurs because the contact surfaces in question slide against each other. It allows the metal inner part of the metal hinge sphere (2) to carry mechanical loads. polyamide coating (3) while forming the main body, metal joint sphere (2) POM It is located on the outer surface that is in contact with the bearing (4). The POM bearing (4) is metal. It forms the element that supports the joint sphere (2) inside the joint (1). POM and the combined action of nylon-based surfaces, the friction and This forms the basis of the wear characteristics. 10 In the joint (1), between the polyamide coating (3) and the POM bearing (4) The contact area contains plastic-compatible grease. Plastic-compatible grease is polyamide. chemically compatible with the coating (3) and POM mattress (4) is selected. In one application, plastic-compatible grease; lithium soap-based, silicone-based or It is one of the greases containing PAO (polyalphaolefin). 15 Plastic compatible grease between polyamide coating (3) and POM bearing (4) By being located in the contact area, the two polymer surfaces in question are lubricated during contact. under these conditions they move against each other. Thus, the metal hinge sphere (2) The metal surface is not used as the surface that works directly with the POM bearing (4), Polyamide coating (3) on the outer surface of the metal hinge sphere (2) with POM bearing (4) 20 It forms a mutually interactive surface. The joint (1) also includes a rubber-backed cover (5). Rubber-backed cover (5), metal joint ball (2) in bearing arrangement inside joint (1) and It is positioned together with the POM bearing (4). The rubber-supported cover (5) is attached to the joint. (1) to withstand the axial loads acting on it and to support the bearing of said loads 25 It contributes to its extinction within the system. Polyamide coating (3) on the surface of the metal hinge sphere (2), metal It is located in the region where the joint sphere (2) contacts the POM bearing (4). Therefore, the basic contact pair of the joint (1) moves relative to each other during operation It is formed by polyamide coating (3) and POM mattress (4). 30 Polyamide coating (3), POM bearing (4) and plastic compatible grease together. In this contact system where it is used, the moisture and lubrication conditions of the metal surface 6 to prevent its use as a friction surface that is directly exposed to changes The friction and wear conditions between the joint sphere (2) and the bearing are being passed through. It is determined via the polyamide-POM contact pair. In the technical design of the invention metal core joint sphere with contact formed from different polymer materials.
