Abstract

The utility model relates to a bearing which is relative to rotary components. The service life of the existing bearing is about six months, and is even shorter in the heavy-load and high-speed conditions. The existing bearing needs to be periodically changed when the machines stop work. Therefore, the manpower and the material resources are consumed, and the field of employment is limited. The utility model provides a bearing of the rotary components among the sleeves, the surface of the bearing is coated with a plating, the internal and the external sleeves of the bearing are provided with the plastic, and the hot compacting adopted in the bearing. Because the bearing has the properties of self-moistening, less friction, abrasion resistance and no temperature rise in friction, the service life of the utility model is higher more than 10 times than the service life of the existing bearing. Besides, the utility model has the advantages of static electricity resistance, easy processing, low cost and high mechanical efficiency. The utility model can be used in the heavy-load and high-speed operating conditions and in the fields of remote control, remote measuring, satellites and spaceflight.

Description

Long life bearing

The utility model relates to technical field of general engineering, particularly relevant with rotatable parts bearing.

There is relative movement between rotatable parts and supporter; bearing is transferred in the bearing support contact friction position between the two; and occur with the form of rolling friction; brought into play positive role to keeping machine or effective operation of apparatus; so bearing has obtained using widely; but there is friction that wearing and tearing are just arranged; under the prior art; the service life of bearing is about six months; heavy duty; under the high speed operation; its life-span is shorter; mainly, change bearing, should consume manpower and materials so the machine or necessary regularly shutdown of equipment of bearing are housed because bearing member wearing and tearing and temperature arrising caused by friction distortion cause; out of service again or produce; the economic loss that causes under the situation of changing inclement condition is just bigger, and the remote control that is in operation and is difficult to change; remote measurement; satellite; fields such as space flight use bearing just to be restricted; because the constraint that is subjected to bearing working life of the machine or the equipment of bearing is housed, as seen prolongs the bearing economy in working life; technical meaning is very big.

The purpose of this utility model provides a kind of bearing of longer service life.

For achieving the above object, the utility model is set about from the operating conditions of improving between friction member, a kind of bearing of being made up of inside and outside cover of bearing and inner room rotating component is provided, it is characterized in that inner room rotating component surface is coated with from moistening antifriction, wear-resisting, the emery that do not heat up of friction--molybdenum alloy coating, the inside and outside cover of bearing are by being tackiness agent based on modified urea-formaldehyde resin, the plastic hot of knitting attitude fiber, plumbago, zine stearate, hexamethylenetetramine and oxalic acid and be filler is molded, have from moisten antifriction, wear-resisting, friction does not heat up performance such as antistatic.

Be described further below in conjunction with embodiment of the present utility model and accompanying drawing thereof.

Accompanying drawing is the structural representation of bearing.

Present embodiment is made up of bearing inner sleeve 1, bearing outside 4 and inner room rotating component 2, inner room rotating component 2 surfaces are coated with emery--molybdenum alloy coating 3, coating 3 thickness are 0.05～0.15mm, bearing inner sleeve 1 and bearing outside 4 by based on modified urea-formaldehyde resin, knit attitude fiber, plumbago and zine stearate, hexamethylenetetramine, oxalic acid plastic hot molded, the ratio of the weight of first three items material is about 2:3:1, and the weight sum of back three prong materials is no more than 5% of material gross weight.

The bearing that the utility model provides is owing to have from moistening antifriction, wear-resisting, friction premium properties such as do not heat up, service life improves greatly, through test, service life as long as five years more than, for existing more than 10 times of bearing, more be applicable to fields such as heavy duty, high speed operation condition and remote control, remote measurement, satellite, space flight.

Though the inside and outside cover of the utility model bearing is made of plastics, and has anti-static electricity property, be suitable for using in antistatic place.

The utility model frictional contact surface is highly polished, and energy consumption descends during operation, and mechanical efficiency improves.

The utility model processing is easy, with low cost.
