Abstract

The invention provides a polyester-aramid guide bearing, a thrust disc friction plate and a manufacturing method thereof. The invention is characterized in that the guide bearing made of polyester and aramid and the thrust disc friction plate form a friction pair; the outer part of the guide bearing is a tube wall, and a water flow groove is arranged in the tube wall; and the thrust disc frictionplate is arranged on a cast iron base. The manufacturing method comprises the following steps: drying polyester-aramid resin cloth soaked with polyvinyl butyral modified phenolic resin, extruding thecloth with a tube coiling machine, placing the cloth into a guide bearing compression die and a thrust disc friction plate formation die, and pressing for formation under the certain pressure and certain temperature. The invention improves the wear resistance and mechanical strength of the polyester-aramid guide bearing and the thrust disc friction plate manufactured in the method. Moreover, the polyester-aramid guide bearing and the thrust disc friction plate have the advantages of simple structure, low cost, less pollution, long service life and the like.

Description

1. Technical field: [0001] The invention belongs to the technical field of lubricating bearing manufacturing, and mainly relates to a friction pair composed of a guide bearing made of polyester or aramid and a friction plate of a thrust plate and a manufacturing method thereof, in particular to a friction pair for a submersible motor. A friction pair composed of a guide bearing made of polyester or aramid and a friction plate of a thrust plate and a manufacturing method thereof. 2. Background technology: [0002] In the past, the domestically produced guide bearings for submersible motors were generally made of ZQpb25-5 lead bronze through casting and machining. The disadvantage is that a large amount of lead elements overflow and pollute the environment during the casting process, which is very harmful to people; This kind of bearing requires a large gap between the shaft and the guide bearing, generally 0.19mm, so it is easy to cause uneven air gap between the rotor and s...
