Description
One, technical field:
The invention belongs to lubricating type bearing manufacturing technology field, relate generally to a kind of terylene, aramid guide bearing and thrust disc friction plate and manufacture method thereof, particularly relate to a kind of terylene, aramid guide bearing and thrust disc friction plate that is used for submersible motor with and manufacture method.
Two, background technique:
In the past, the guide bearing that is used on the submersible motor of domestic production generally was to form through casting and machining with the ZQpb25-5 lead bronze, and its shortcoming is to have a large amount of lead elements to overflow befouling environment in casting process, and is bigger to hazard to person; This bearing requirement axle and guide bearing gap are big, generally at 0.19mm, therefore cause air gap inequality between rotor and stator easily, make the motor performance instability or eccentric wear occurs.Also having with rubber is the bearing that main body is made, and the shortcoming of this bearing is that rigidity is low, distortion is big, axle is had bigger loss of machine of torque; The thrust button of domestic production, the general 4Cr13 stainless steel of using, through heat treatment, machining is made, and the thrust button procedure of this made is loaded down with trivial details, waste energy, the 4cms stainless steel easily produces phase transformation in heat treatment, internal stress is difficult to eliminate, if thoroughly do not eliminate internal stress in 72 hours, will produce crackedly, and manufacturing process is complicated.The Japan clear 57-33221 of special permission communique has narrated a kind of asbestos cloth by impregnated phenolic resin and has been rolled into the lubricating type bearing that the multilayer vortex forms; The clear 57-47025 of day disclosure special permission communique has narrated and has a kind ofly made ordinate with asbestos fiber, make the lubricating type bearing that the fabric of horizontal line is made through winding with phenolic fiber, the advantage of these two kinds of bearings is good hydrophilic property, is suitable for using in water and seawater medium, its shortcoming is that phenolic resin has many phenolic hydroxyl groups, when solidifying, because condensation reaction always will be emitted many water molecules, and outwards overflow, form a large amount of bubbles and microchannel, thus wear no resistance, fragility is big, influenced working life.
Afterwards, asbestos iron guide bearing and thrust disc friction plate have appearred again, its main points are with air dried dipping polyvinylbutyral phenol-formaldehyde resin modified chemical fibre resin cloth, but asbestos are carcinogenic substances, forbid in the world, domesticly also ban use of, and the domestic asbestos deposit that sealed, asbestos iron can not use.
