Description

Technical Field

[0001] The utility model relates to the technical field of air bearings, in particular to an anti-impact testing device for detecting air bearings. Background Art

[0002] Air bearings (also known as air bearings) refer to sliding bearings that use gas (usually air, but it may also be other gases) as a lubricant. They consist of an inner ring and an outer ring of the bearing. The outer ring has air inlet and outlet holes, and the inner ring has a nozzle. Air bearings are a new type of bearing that uses the elastic potential energy of air to support it. Air has lower viscosity than oil, is resistant to high temperatures, and is pollution-free. Therefore, it can be used in high-speed machines, instruments, and radioactive devices, but its load capacity is lower than that of oil. Air bearings are divided into three categories: air static pressure bearings, air dynamic pressure bearings, and squeeze film bearings. In general industry, air static pressure bearings are widely used. In the actual use of air bearings, different working conditions are often encountered, and the mechanism is often impacted. After the production and processing of air bearings are completed, the workpiece needs to be tested for impact resistance, but the existing impact resistance testing equipment is not accurate in impact testing of workpieces.

[0003] When the existing equipment performs impact resistance testing on the workpiece, the workpiece is prone to shaking, and the workpiece cannot be conveniently supported and fixed stably. In addition, the impact force of the workpiece cannot be conveniently adjusted when the existing equipment impacts the workpiece, which affects the accuracy and practicality of the equipment's impact resistance testing of the workpiece.
