[Previous technology] A bearing is a special object that can reduce the wear of parts during relative movement. Σα tunnels different applications and designs. The types of known bearings are also very diverse. For example, bearings using balls as a means of reducing friction are called For the ball bearing, the roller bearing is called a roller bearing, and the new patent case No. 265807 is to provide a lubricant that can automatically bleed out when running. For an effective lubricating bearing, the needle of the present invention = the manufacturing method of such a lubricating bearing is improved. > Read the three-dimensional and cross-sectional views of a conventional lubricating bearing not shown in the first figure. The conventional lubricating bearing can not be judged. The shaft sleeve is a relative moving workpiece i 〇, and can be designed according to the mechanical body. * * It is necessary to make an axial reciprocating motion or a twirling rotation with respect to the relative moving workpiece 10. The above-mentioned lubricating bearing 1 includes: a metal base 11 and most of the mountains t ^ _ Xi Xi is buried in the base The lubricating block 12 ′ on the seat 11, wherein the base 11 is generally made of copper-containing alloys, such as tin-green steel, bronze-filled, etc., and has an inner ring wall surface which is arranged around a central axis of itself. 111. An outer ring wall surface η 112. Most of the fitting holes 113 penetrating radially through the inner and outer ring wall surfaces 111 and 112. An annular outer oil groove 1 1 4 that is recessed inward from the outer ring wall surface Π 2 An inner oil ditch 凹 recessed outward from each inner wall surface 111 from the inner g ^ 5. An oil hole 116 radially penetrating the inner, outer, mountain, and lane oil ditch 11 5, Π 4, and an inner ring wall surface 111 circles came out and provided for relatively moving workpieces 1 through sleeve 568985 玖, invention description (2) through sleeve hole 117 ', and such lubrication $ 12 The system is embedded in the fitting hole 113 of the base ^, and the lubricating block 12 is usually added to the graphite by adding molybdenum disulfide (MOS2), the function is to make the lubricating block 12 = The function of grinding and containing lubricating oil, each lubricating block 12 has a radial inner end surface 12 which matches with the inner ring wall surface 1 1 1 radian, and a radial outer end surface 1 which matches with the outer ring wall surface 11 2 radian twenty two. In the second figure of the port, in order to manufacture the conventional lubricating bearing 1 shown in the first figure, a known processing step first forms a prototype of the base u, and then forms the fitting holes 113 on the prototype of the base 11. , 1 ... hole- to make the base U, and then make a strip-shaped lubricant in molybdenum disulfide, and plug the lubricant --- into the fitting hole 113 of base = 11 to form These lubricating blocks 12 may be the same day as the lunar moon ghost 12 is filled. In order to take convenience into account, the outer diameter of the strip lubricating block 12 is generally slightly smaller than the diameter of the fitting hole ι3 in the base. After the sleeve is inserted, the combined body is fixed by heating. After the fixing, the radial inner end surface 1 2 of the slider 12 and the radial outer end surface 22 will be slightly out of the base 11 The outer ring wall surfaces 111 and 112, therefore, after filling, it is necessary to use a grinding process to lubricate the protruding outer surface of the ring wall surfaces 111 and 11 2 and remove the 2 to the radial inner end surface 1 2 1 of the lubricating block 12 and the base. The inner J-clothing wall surface 111 of the seat 11 is continuous and integrated, and the radial outer end surface 12 and the outer ring wall surface U2 of the base 11 are continuous and integrated. When such a known lubricating bearing 1 is used, it is actually a relative rotation or an axial reciprocating motion between the lubricating bearing 1 and the relatively moving workpiece 10. The above-mentioned motion mode is set as required, and the following is based on relative movement. 568985 Description of the invention (3) The moving workpiece 10 can be used as a lubricant in comparison with the lubricating bearing and the sliding bearing 1. H% is used as a description, that is, the square of the inner ring wall surface U1 which is located on the base " The wall surface is adhered to heat, at this time == nrui relative motion gradually releases friction, and the oil can form lubricating 1 # due to temperature rise. The surface of the moving workpiece 10 is known to adjust the sliding bearing directly. Two: The use of two bearings 1. The lubricating lubricating block 12 of the lubricating oil is embedded and wear-resistant and can contain inclusions. However, the design of the item "Hai" will result in the following defects: Non-12: The material height: b Lubricating shaft 7 ... Designing the lubricating block 2 There is a lot of space between the base U '. Therefore, in terms of cost, the volume of the Dragon 1 2 accounted for the entire production cost per month. The 10-door combination Γ has the inner ring wall surface 111 and the relative displacement a, which means that relative movement and friction occur. Therefore, the radial inner end surface 121 of the respect 12 is distributed on the inner ring wall surface 111. Although it means two: to the item, The conventional lubricating bearing is embedded with a lubricating block = 1: the lubricating block 12 with the same thickness on the top 11 is used. When lubricating the bearing! When using 1 :: and wear, the wear described here is generally equal to the loss. In terms of the axial fitting, it is necessary to: The dimensional accuracy of the workpiece 10 and the lubricating bearing 1 is not good enough. The lubricating bearing 1 is used to maintain the accuracy between each other, and when lubricating the car ^ thickness When it is known that 0.2 is ugly and is replaced, the lubricating block with high raw material cost is 568985 玖, the description of the invention (4) caused the material cost 2 in fact It is the case where the thickness is very small, and it is discarded and wasted. First, ..., both the structural strength and the lubricating effect are taken into account: The conventional lubricating bearing 1 is mainly known for its wide ^, μ & w as described above. The lubricating effect is produced by the 1U of the core wall surface of the base 移动 and the relatively moving workpiece. Therefore, the more wear-resistant lubrication points on the inner ring wall ® 111 of the US seat 11, the more lubrication: "The more ideal" The wear-resistant lubricating point mentioned here refers to the lubrication & ^ of = the surface area of the inward end surface 121 'and it can be known from the design of the conventional lubrication H 1 that the lubricating block U is radially arranged in sections. On the base u, considering the overall structural strength, the area of the fitting hole 嵌 embedded in the lubricating IU needs to be limited, resulting in the radial inner end surface 12 of the lubricating block 12 " occupation = two: the annular wall * 111 has a limited area That is, it is limited by the overall structural degree. The lubricating effect of the moisturizer 12 is distributed on the inner ring wall. This will not only cause the lubrication effect to be unsatisfactory, but the failure to control the steering gear ... 13 will also affect the base. ; The structural strength, this ^ know turbid slip axis fantasy can not take into account both the structure Reasons for strength and lubricating effect 0 [Summary of the Invention] The present invention is to provide a method for manufacturing a lubricating bearing which can reduce material cost, structural strength and lubricating effect.
