Gleitlagerprüfstand

A Gleitlagerprüfstand, or sliding bearing test rig, is a specialized piece of laboratory equipment used to evaluate the performance, durability, and tribological properties of plain bearings under controlled conditions. These test stands simulate real-world operating conditions to assess factors such as friction, wear, temperature, and load-bearing capacity, ensuring reliable and efficient operation in mechanical systems.

Gleitlagerprüfstands are commonly employed in industries such as automotive, aerospace, machinery manufacturing, and energy production, where sliding bearings play a critical role in reducing friction and facilitating smooth motion. The test rig typically consists of a rotating or oscillating shaft, a bearing housing, a load application system, and sensors to measure key parameters like torque, temperature, and wear rate. Some advanced setups may also incorporate lubrication systems to study the effects of different lubricants or lubrication methods.

The primary purpose of a Gleitlagerprüfstand is to validate the design and material selection of bearings before mass production. By subjecting bearings to accelerated testing—such as high loads, extreme temperatures, or cyclic loading—the test rig helps identify potential failure modes, optimize lubrication strategies, and improve overall bearing performance. This reduces the risk of premature wear or catastrophic failure in operational machinery.

Different types of Gleitlagerprüfstands exist, including steady-state rigs for long-duration testing and dynamic rigs for simulating variable operating conditions. Some advanced test stands incorporate computer-controlled systems for data acquisition and analysis, enabling precise monitoring and real-time adjustments. The results obtained from these tests are essential for refining bearing designs, improving manufacturing processes, and ensuring compliance with industry standards.
