Abstract

A novel ceramic chamber lining comprises a lining (10), narrow pores (11), lubricant (12) and so on, and narrow pores (11) filled with lubricant (12) are arranged densely in the inner of the whole lining (10). The space with narrow pores (11) distributed accounts 1-5% of the total volume of the lining. While novel ceramic chamber lining of the utility model- is used, the abrasion resistance of the lining is improved because of the hard material of ceramic, and lubricant accumulates in the gap of a rotary axis and the lining due to the capillary action, thus the friction between the rotary axis and the lining is reduced, the rotary speed is advanced as a result, the service life of the rotary axis and the lining is prolonged.

Description

A kind of new ceramics lining

Technical field:

The utility model relates to a kind of ceramic chamber lining, is specifically related to a kind of ceramic chamber lining and turning shaft structure that can effectively reduce pivoting friction and improve rotating speed.

Background technique:

The effect of lining mainly is to cooperate with rotating shaft, to stablize the spinning movement of rotating shaft.Modal lining is used for the running of common mechanical device more, as using on motor, fan.Wherein, be applied in employed lining in the radiation fan rotating shaft,, and need long-time running, therefore, because of the excessive friction between rotating shaft and the lining causes damage, influence the normal operation of fan through regular meeting owing to the rotating speed of fan itself is had relatively high expectations.In the prior art, there is change by material itself to increase wear resistance between lining and the rotating shaft, also has between rotating shaft and lining, to add oiling agent and reduce friction, and avoid producing noise and heating, reduction working life because of rubbing action is excessive.Its rotating shaft and lining are made by pottery, and surface roughness is controlled between the 0.1 μ m-1.6 μ m, and do not need oiling agent still can go slick this moment.But its shortcoming is: strict surface roughness control requires accurate processing technology to realize, has promoted technology difficulty.When the precision of processing was not good, the wearing and tearing meeting when rotating shaft and lining running was more serious, and mechanicalness noise also exists equally.

Summary of the invention:

The purpose of this utility model is to provide a kind of effect by pore lubricant layer to be filled in the pore of bush inside, with a kind of new ceramics lining of the pivoting friction that reduces rotating shaft.

The purpose of this utility model is achieved through the following technical solutions.

A kind of new ceramics lining comprises lining (10), pore (11), oiling agent compositions such as (12), is to be densely covered with pore (11) in the inside of whole lining (10), and filling has oiling agent (12) in pore (11).

The distributive law of pore (11) accounts for the 1-5% of lining total volume.

The utility model ceramic chamber lining in use, because the hard rigid material of pottery has improved the wear resistance of lining itself, and its oiling agent is accumulated in the gap of rotating shaft and lining by capillarity, reduced the friction of rotating shaft and lining, and then lower the high temperature that causes because of friction, promote the rotating speed of rotating shaft, prolong the working life of rotating shaft and lining.

Embodiment:

Ceramic chamber lining of the present utility model is formed by the ceramic raw material sintering, gathers by pore 11 in the inside of whole lining 10, and filling has oiling agent 12 in pore 11.Its working process is that ceramic powder is mixed mutually with pore agent such as active carbon or graphite, and the mode with ejection formation or extruding and moulding fashions into the needed body of lining, specification, size with above-mentioned raw materials again, and further high temperature sintering is body fixedly.Ceramic raw material is in the sintering type-approval process, and the carbon dioxide that is discharged by raw material forms the pore that is clouded in bush inside 1-5%.

After the body of lining is finished sintering, as shown in Figure 2:, make oiling agent 12 inject the pore 11 of lining 10 to take out the mode of system vacuum; Or as shown in Figure 4: with the pore 11 of pressing mode, hold proper amount of lubricating agent 12, promptly finish the whole course of working of lining 10 by pore 11 with oiling agent 12 injection linings 10 inside.

Lining 10 cooperations are applied to motor or various mechanical transmission, as shown in Figure 5: cooperate a ceramic axostylus axostyle 22 in the rotating shaft 21 of radiation fan 20, and increase its practicability.

Claims

1, a kind of new ceramics lining comprises lining (10), pore (11), oiling agent compositions such as (12), it is characterized in that: be to be densely covered with pore (11) in the inside of whole lining (10), and filling has oiling agent (12) in pore (11).

2, ceramic chamber lining according to claim 1 is characterized in that: the distributive law of pore (11) accounts for the 1-5% of lining total volume.
