Embodiment Construction

[0039] The hard particles are preferably composed of materials that do not chemically react with the materials of the parts to be joined or with environmental media under certain conditions of use. The material is preferably an inorganic material.

[0040] Preferably, the hard particles are selected from the group consisting of carbides, nitrides, borides, silica, alumina, diamonds, and mixtures thereof. Examples of carbides are silicon carbide, tungsten carbide, and boron carbide; examples of nitrides are silicon nitride and cubic boron nitride. Preferably, diamond is used as the hard particles.

[0041] The size of the hard particles is selected in such a way that the damage to the surface due to the particles being pressed into the joining surface does not reach an unacceptable level. Preferably, this can be ensured if the particle size is not more than about three times the height of the peak-valley of the joining surface, where the peak-valley is produced by machining the jo...

Abstract

The present disclosure relates to a connecting element and to a process for producing said connecting element. The present disclosure further relates to a connecting system and a device comprising said connecting element, and to a process for fixing said connecting element to a first component. The present disclosure further relates to the use of said connecting element and connecting system for friction-increasing connection of a first and a second component in energy generation, specifically in wind turbines and hydropower turbines, and in machine, plant, motor vehicle and aircraft construction.

Description

Technical field [0001] The present disclosure relates to connecting elements for friction-increasing connections of parts to be joined. Background technique [0002] Force-locked connections are often used to transmit force or torque in all areas of machinery, equipment and motor vehicle structures and energy generation. The magnitude of the force that can be respectively transmitted not only depends on the structural design, but also mainly depends on the static friction value (static friction coefficient) of the surfaces of the connected parts. Therefore, as far as this type of force lock connection is concerned, efforts are being made to provide friction increasing measures that allow the safe transmission of the maximum possible lateral force and torque. In addition, the force-locking connection can also be referred to as a non-positive connection or a friction connection. [0003] It is known that friction increasing interlayers are used to increase the holding force or incr...
