Problems solved by technology

[0003] However, the bonding technology of AIRFLON bushings is an advanced technology in the world. Foreign countries impose material embargoes and technology blockades on my country, and it is difficult to obtain detailed technical details.
Therefore, the bonding effect is poor, and it is difficult to meet the actual needs, thus restricting the comprehensive localization of domestic landing gear technology

Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with specific embodiments.

[0058] The AIRFLON bushing involved in the bonding method of the AIRFLON self-lubricating bushing of the present invention is that a cushion layer is glued on the working surface of the metal bushing. This cushion is a self-lubricating layer between two parts that move relatively. It is a composite cloth woven from aramid fibers (or glass fibers) that can maintain high strength under heavy loads. It is called AIRFLON lining and has low friction. coefficient.

[0059] see figure 1 , which is an assembly diagram of the bonding method of the AIRFLON self-lubricating bushing of the present invention. In the figure, the AIRFLON bushing 2 is set on the metal mandrel 1, and then put into the metal bushing 3 to form the AIRFLON bushing.

Abstract

The invention belongs to the transmission lubrication technology and relates to a method for bonding an AIRFLON self-lubricating bushing. The method comprises the following steps of: determining an AIRFLON lining, an adhesive and the material and size of a core rod; performing surface treatment on the surface of the metal bushing and before blanking, ironing the work surface of a cushion layer; cleaning a bonding surface, applying the adhesive to the bonding surface of the metal bushing, removing the redundant adhesive, clamping the AIRFLON cushion layer by using tweezers and bonding to the bushing coated with the adhesive, and after bonding the cushion layer, putting a core shaft with a small size into the bushing to roll and pressurize the cushion layer, so that the cushion layer is smooth; and preheating, baking, and cooling naturally to bond the AIRFLON bushing. The obtained AIRFLON bushing is high in bonding quality, stable and reliable, the expected aim of design is fulfilled, and large economic benefit can be obtained.

Description

technical field [0001] The invention belongs to transmission lubrication technology and relates to a bonding method of AIRFLON self-lubricating bushings. Background technique [0002] AIRFLON bushing is a kind of self-lubricating bushing used in the structure of helicopter landing gear. AIRFLON bushings are widely used in landing gear, and the rotating and movable parts of helicopter landing gear and strut actuators all use AIRFLON bushings. AIRFLON bushing has good wear resistance, high and low temperature resistance, and can work for a long time under the condition of -60℃~120℃. It is very suitable for working under low speed and high load, and it has self-lubricating property, no additional lubrication system is needed. It is much simpler and more reliable than the structure of the metal "bearing bush" commonly used. [0003] However, the bonding technology of AIRFLON bushings is an advanced technology in the world. Foreign countries impose material embargoes and techno...
