Slide bearing arrangement i.e. radial sliding bearing, for parabolic trough collector arrangement in solar power plant, has actuator displaced for reducing friction at slide bearing surface kept in oscillations

摘要

The arrangement (100) has a bearing element (110) i.e. supporting roller, for bearing a bearing ring (101). An ultrasound emitting actuator (130) is displaced for reducing friction at a slide bearing surface kept in oscillations. A bolt (120) axially bears the bearing element, and the actuator is arranged in a hole of the bolt. The bolt is indirectly connected with the bearing surface such that the actuator transfers the oscillations to the bearing surface over the bolt. The bearing surface is formed as a part of the bearing element. The roller is supported on a slide bearing case. An independent claim is also included for a method for reducing friction of slide bearing arrangements.
