Abstract

The invention relates to a detection and testing device for the friction performance of a joint bearing liner and a mounting method of the detection and testing device and aims to solve the problem that the spindle of a detection device for the friction performance of a self-lubricating liner breaks easily under high-rotation-speed and small-size conditions. The detection and testing device is characterized in that a cylindrical metal ring is arranged on the outer side of a spindle in a matched manner, a conical hole and a circular hole which are communicated are arranged in the middle of the metal ring in a penetrating manner, the taper of the conical hole corresponds the conical section of the spindle, and the diameter of the circular hole corresponds to the small diameter section of the spindle; the maximum diameter of the conical hole is smaller than the maximum diameter of the conical section. The detection and testing device has the advantages that the connection structure of the spindle and a friction pair allows the spindle to be stable in operation and less prone to breaking, taper face combination increases contact area, the friction force between the spindle and a joint bearing is increased, and swinging force can be transmitted stably.

Description

technical field [0001] The invention belongs to the field of testing devices for detecting the friction performance of pad materials of joint bearings, and in particular relates to a device for testing the friction performance of a self-lubricating pad of a high-speed light-load small-size hybrid ceramic self-lubricating joint bearing and an installation method thereof. Background technique [0002] At present, the aviation field is gradually developing in the direction of high speed, heavy load, long range and good maneuverability, and the corresponding bearing components also require higher performance and reliability. As a key component in the aviation industry, the performance of the self-lubricating joint bearing has an important impact on the working performance and safety of the aircraft. The quality and tribological properties of the self-lubricating liner material in the self-lubricating spherical plain bearing directly determine the performance and life of the self...
