Press composite for use as component of pump utilized to supply e.g. lubrication oil to combustion engine of motor car, has mixtures arranged in respective surfaces of joining parts, and containing hard material particle in carrier mass

摘要

The composite has a joining part (2) with a joint surface (4) that is connected to another joint surface (3) of another joining part (1). Mixtures (6) arranged in the joint surfaces contain a hard material particle in a resilient carrier mass. The parts are formed as respective shafts, where a rotational torque is transferable over the joint surfaces. The parts form respective inner and outer parts in the joint surfaces. The mass contains an elastomer or a natural rubber. The particle is made of ceramic particles and sand, and consists of silicon dioxide, silicon carbide and diamond particles. An independent claim is also included for a method for manufacturing a press composite.
