Metal elements3/28/2023 ![]() The static load distribution, as well as further parameters (e.g. Therefore, certain input variables should be considered when designing rubber-to-metal elements. If this circumstance is not taken into account in the design and layout of the bearings, these components can fail in use after a short period of operation, which can cause further damage to the machine. As a result, individual machine feet are exposed to higher static and dynamic loads than others. However, if the machine is designed asymmetrically, the load is distributed unevenly. If the center of gravity is exactly in the middle, all pedestals are equally loaded. In addition to the component geometry and hardness, which are decisive for the stiffness of the bearing, the installation situation of the bearings and the geometry of the machine also play an important role in terms of static load and dynamic performance. This is the case, for example, with machine feet. ![]() If rubber-metal elements are to carry large loads, for example, in addition to the component geometry, the weight distribution / center of gravity of the system is also of great importance. In this way, you avoid damage to the adhesion promoter. Therefore, it is important to reduce the exposure and molding times of rubber-to-metal elements. However, injection molds are pre-tempered to speed up the vulcanization process. If it is damaged or compromised, there is a risk that the bond between the rubber and metal will be impaired.įor example, the adhesion promoter can be damaged if it is exposed to high temperatures for too long. It is important that the adhesion promoter also receives attention during production. Strictly speaking, rubber-metal elements therefore consist not of two but of three elements: Elastomer, metal and adhesion promoter. Companies typically use an adhesion promoter that serves as a chemical bridge and improves the adhesion properties of both elements. While it is possible to create a direct bond through process control and compatibility of the two components, this requires considerable effort and know-how. Rubber and metal do not easily form a permanent bond.
