Abstract

The invention discloses a manufacturing method of a PTFE (polytetrafluoroethylene) fabric self-lubricating spherical plain bearing. The manufacturing method comprises the following steps: one surface of a PTFE fabric liner is coated with glue A which is irreversible after curing; the fabric coated with the glue A is subjected to rolling treatment; the fabric liner is cured by adopting a panel hot-pressing technology; the cured fabric liner is cut into a size suitable for an inner spherical surface of an outer ring of the spherical plain bearing; the inner spherical surface of the outer ring or the other surface of the fabric liner is coated with glue B; then the fabric liner is adhered to the inner spherical surface of the outer ring through the glue B; an inner ring of the spherical plain bearing is sleeved into the outer ring of the spherical plain bearing, which is adhered to the fabric liner; the cured surface of the fabric liner faces to an outer spherical surface of the inner ring for mutual coupling and contact; the periphery of the outer ring is sleeved with a curing lantern ring; and the bearing is put into an oven for oven heating. The curing method not only can ensure the strength and abrasion resistance of the fabric liner, but also avoids the step of coating the outer spherical surface of the inner ring with a mold release agent.

Description

technical field

[0001] The invention relates to a method for manufacturing a PTFE fabric self-lubricating joint bearing. Background technique

[0002] In the existing PTFE fabric self-lubricating joint bearings, the curing time of the PTFE fabric liner is to heat and cure at the same time after being assembled with the inner ring and the outer ring. Firstly, the colloid A is coated on the friction surface of the fabric liner, and the colloid A B is coated on the adhesive surface of the fabric liner, and then pasted on the inner spherical surface of the outer ring, loaded into the inner ring coated with a release agent on the outer spherical surface, and then pressed into the curing collar, and finally placed in the oven in the setting Curing is carried out at a certain curing temperature and baking time.

[0003] Problems in this method: 1. The release agent coated on the outer spherical surface of the inner ring is attached to the outer spherical surface of the inner ring ...
