Description

1312016 IX. Description of invention: [Technical field to which the invention belongs] The motion-to-system used in the existing industry can be divided into two types: contact and non-contact. Among them, non-contacts are mostly magnetically suspended or air-suspended as =, based on manufacturing. Cost and system control and the cost and complexity of equipment maintenance, so in addition to the use of precision, high-value equipment, for a & ^ motion to it, rolling and sliding contact movement pairs Design ^ is the main application technology. (7) Dynamic motion design, generally using lubrication between the two sliding elements =, self-lubricating oil-filled gasket or soft transition material, which is more economical by adding lubricating oil, but it is added to New Zealand oil. Closed ^, the mechanism of the mechanism of oil-free pollution can not be used, the soft transition J· is refined by its own easy wire and replaceable characteristics, instead of sliding to the body, but because of the soft material Wear problem, so the change in the size f degree of the positioning is large, and the fine particles produced by the soft mass are still serious pollution to the system, self-lubricating oil-containing lining or shaft acre, wt . The average price is lower 'because it has the lubricating oil automatically oozing out the lubrication=, in terms of the dimensional tolerance of the rotating shaft and the bearing combination, the gentleman is very good, but the lubricating oil consumption and the oil impregnation rate are affected by the working temperature and the substrate. The influence of the difference coefficient value, etc., on the movement of the higher i motion degree and the § 'poor life, such as: self-lubricating bearing, but far less than the 5GGiKM of the ball bearing, when it is applied to the rolling type Saki design, with traditional roller bearings as the bulk of the ίί ϊ 命 r r 由 由 由 由 由 由 r r r r r r r 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合 组合1312016 A number of rolling bearing devices are used on fixed linear guides to achieve linear motion. However, due to noise problems caused by contact and impact between the rollers and the road, the average price is higher than that of self-lubricating oil-impregnated bearings. Limited by the alignment and adjustment techniques of several ball linear assemblies, it is also a major limitation. [Previous technology], developed by THE GLACIER METAL CO., LTD. on the market, and obtained patents from the United Kingdom, Japan, the United States, Canada, France, Italy, Germany, Switzerland, etc. (Japanese patent number 2236〇) 5 and 438282) DU is completely unsupported, bearing, which is sintered on the steel to make the bronze powder porous, and the Teflon-lead/mixture is filled with the impregnated surface as a Teflon-lead film, bearing The surface often has Teflon-lead and therefore low friction, so no lubricating oil is needed. The Teflon-lead-impregnated bronze sintered layer is about 3 mm thick. Due to the function of this structure, the wear and tear of the = phase will be about G Glmm. Among them, the steel gold is the strength function to ensure the bearing's solidity 'size precision, stability and correct torque tightness'. The products using this process technology have ordinary bushings, thrust bearings, crocodile linings. The set, the moon plate, is the cross-sectional structure of the process product. This technology is based on the surface of the gold substrate of the steel, and the surface of the gold substrate is coated with a layer of bronze-based powder and then formed into a layer of porous structure, and then the mixture of Teflon-wrong is Teflon-domain film. Among them, the bronze-based powder particles of Shi Tianxi iron-fluoride I-lead filling material, the process technology on the porous surface 蜱 knot t must consider the high temperature combination of the substrate and the bronze-based powder, otherwise easy to produce ίί, In the case of separation, the sintering temperature of the bronze machine powder generally needs to reach 76 〇. It is used to thermally deform the gold substrate in the steel. After the Teflon-lead is filled on the surface of the smectic surface, f is heated to the moment. Above C, it can be combined with Qingna, and this high; h; °-3raffl ol ί, the raw material contains _ ingredients also violates the existing information regulations, so its use value is greatly affected. 6 1312016 [Inventive content] Miscellaneous iiti f, the invention is a whistling and rolling life, low f tl! i traditional bushing friction coefficient is about G. ‘Ο. Between), Qiu Ϊ 侗 侗 Ilf oil-containing components of low noise, reduce the pollution caused by grease and the second manufacturing cost, improve the technology of the oil-free bearing process, so that the reduction of ^ «, wealth, manufacturing into [ The implementation method] "Process Principle" The fog method is shown as "Like", which is directly used to spray the same grain of the alloy powder, and is initially screened. After that, will not choose) Twenty-two too, pass ~ corpse ""1' is US ASTM standard No. 400 Xuemu _ === (for example: graphite, stearic acid to mouth A, due to different particle size of th The powder and granules are evenly mixed. The design of the r5 twist, mixing mechanism, etc. will affect the original end of the substrate; the second is equal to the degree of the mixture. Therefore, when mixing the powder, it must be in accordance with the size distribution of the powder ίϊί:2? According to the above characteristics, the invention uses the "straight" screw type mixer, and the appropriate rotation speed (6 〇 ~ rpm) is a method capable of achieving uniformity of mixing powder. One. The base powder of the life molding powder program is filled in the presser machine, the upper punch, the lower punch and the middle die press and clamp the principle, so that the squeeze = period ==; = two of the area 1312016 The density value does not meet the above criteria, _ the final product can still meet the requirements of the phase 5, but will increase the processing procedures and impact of subsequent processes, so the requirements for optimizing the forming density, for a large number of students: quality stability And the cost of production is reduced, it is necessary. Used in ασ forming process Lubricant is mainly used to help the raw embryos to escape from the mold and reduce the pressure of the film. The lubrication method can generally be as follows: The second is to mix the dry lubricant with the metal powder and fill it directly. In the hole, pressure forming, and the other method is to use the mold wall lubrication method, that is, before the metal powder is filled into the cavity, the liquid lubricant dissolved in the volatile organic solvent is coated or tilted and (4) The surface is to be volatilized and dried, and the surface of m Lin has a smooth sliding effect. According to the data of the present invention, if the powder of nickel oxide is used to extinguish the powder of powder size and size, and then with appropriate forming pressure, it may not be added. Lubricant & ϊ ϊ = the density after forming is 7.97 g / cm3 'This can also meet the better density requirements of the aforementioned green forming process. The embryo will be sent to the burning branch and 60 in the sintering place under the Wei atmosphere. 1, σ, π is basically an extension of thermodynamics and diffusion, which promotes the effective control of the 11 atmosphere in the powder eclipse, and produces a part of the solid or liquid: the diffusion of the image, so that the secret force can be combined. Words, the system of sintering has changed? 1 includes _, temperature curve, choice of furnace atmosphere, flow of gas, time of stay of high temperature towel and design of furnace structure, so to ensure the successful sintering, the control of the above factors is indispensable. The three steps of the process are as follows: 1. Preheating zone: In this zone, it is mainly hoped that the effect of degreasing and deteriorating can be achieved by thermal energy, and the powder will not be deformed during the sacrifice process. Zone: The main purpose of this zone is to achieve the purpose of densification of the green body by the higher temperature thermal energy effect after the dislocation process of the shaped body through the front section. 8 1312016 Cooling zone: treated by high temperature ship After the completion of the work, # is controlled by the cooling rate of the gradual cold part to determine the metal structure and properties of the shaped body. Heat == hot work, two 1 ί's 'study of the lubricant characteristics, to 45 (rc for the production of two 'line during the overall sintering process' if the heating rate is too fast or temperature change lit 2 stone ί At present, it is also very easy to cause the control of the formed part by a certain rate of enthalpy. The present invention is right-handed by the "right, only.", fruit analysis, in the case where the sintering progress rate of the formed part is controlled at 45 to 55 mm/min. , will get a good sintered part. _ ί ί ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ The transition temperature from the real zone to the formal sintering zone is set at 710 ^^ 25 ?^^^^8〇〇±5〇(:^^ ^ ^#^,1 with a reductive reductive rate at the junction rate, in the cooling zone It takes about 3 minutes to stay. After the sintering process, the molded parts, in general, have a little change. When the accuracy of the right workpiece is not high, the sintered part can be straightened into 1312016. Surface modification and coating treatment, the higher the size, the size finishing process 庠 ^ ^ on the workpiece size After the accuracy is required to be corrected, the subsequent coating is carried out, and the size of the ingot is adjusted to the precision of the grease. ί 精 二 f 2 needs: line surface thermal degreasing treatment 9.

Ethylene ultrafine particles are deposited layer by layer on the solid surface. The order is that when the reaction occurs, the electron transfer does not pass through the external V line, but when the material in the Lok liquid is emitted on the solid surface, it is directly carried out (4). The process temperature is generally maintained in this process technology can be obtained - a collection of hardness, wear resistance 'low friction The composite ore layer of the system has an average friction coefficient of Ni_p ore layer ^ (4) ~ 0. 05) 'But before the coating treatment, various cleaning procedures of the surface of the substrate, such as surface activation treatment 200, 400, surface Modification of 3〇〇, 5〇〇 and 洗Do not wash 110, 210, 310, 410, 510 and other cleaning and activation sites ^ 〇 发 done well, otherwise it will seriously affect the quality of the coating.
