Description of the invention (2) When a lubricating oil is supplied to the sliding part of the sliding member of the sewing machine, for example, the sliding part of a needle bar A needle bar bearing, the lubricating oil is dispersed in the surface portion of the sewing machine, wherein a needle bar mechanism is provided and the dispersed lubricating oil is penetrated on the outer peripheral surface of the needle bar for vertical movement. In order to spread a lubricant on the surface portion, a highly fluid lubricant is required. Therefore, a lubricant with low viscosity must be used. However, when a lubricating oil having a low viscosity is dispersed on the surface portion of the sewing machine, it is quite difficult to properly adjust the supply amount of the lubricating oil. When this regulation cannot be achieved properly, there are many problems. More specifically, if the amount of lubricant supplied to the sliding portion is too large, there is a problem that the lubricant leaks out of the sewing machine from the sliding portion and contaminates the product to be sewn. Conversely, if the amount of lubricating oil supplied to the sliding part is too small, there will be a problem, which will cause a sticking hazard on the sliding part, which will not be stable in the long run. In addition, there is another problem. Due to the complex adjustment work, the Will worsen in usability. In addition, the structure for supplying lubricating oil to the sliding portion also has a problem. The structure of the sewing machine becomes complicated and the number of parts and the time required for assembling increase, which results in an increased economic burden. At present, there is a need for a structure for a sliding member of a sewing machine, which is difficult to supply due to abrasion and glue hazards in the sliding portion during high-speed operation of the sewing machine without a strong supply of oil. A structure has been developed for a sliding member thus used in a sewing machine, in which one of a sliding member and a supporting member is formed by applying an sintered metal to an oil-containing process, and one of the sliding member and the supporting member It is made of anti-abrasive resin.

Description of the invention (a structure formed by a carbon fiber reinforced resin, and the sliding surface of one of the sliders One of the supporting members and one of the sliding surfaces is covered with a hard film, such as TiN or diamond-like carbon, or a lubricating film, such as molybdenum disulfide or fluororesin. [Problems Solved by the Invention] However, it is conventional Used in the sliding members of sewing machines. In the structure formed by applying an sintered metal to an oil-containing process in one of the slide and the support, the amount of lubricating oil will vary depending on the individual components, or the lubricating oil included. The amount cannot be accurately set in the manufacturing stage. Therefore, there is a problem that it cannot be stabilized for a long period of time. In addition, in the sliding member conventionally used in sewing machines, one of the sliding member and the supporting member is made of resin to prevent wear. For example, in the structure formed by a dish of fiber reinforced resin, there is a problem of insufficient abrasion resistance of the sliding members used in the sewing machine, which cannot be stabilized for a long time, and it is necessary to supply lubricating oil to the sliding portion so that the oil-free supply of the sewing machine cannot be achieved In addition, in conventional sliding members used in sewing machines, one of the sliding surface of the sliding member and one of the sliding surfaces of the supporting member is covered with a hard film, such as T i N or similar. Or the structure of a sliding film, such as a disulfide box or a fluororesin, has the problem of insufficient abrasion resistance of the sliding members used in the sewing machine, the problem of instability for a long time, and the lubricant must be slightly supplied to the sliding part so that The same way that one of the surfaces is formed with an anti-abrasive resin cannot meet the problem of an oil-free supply sewing machine. Therefore, it is necessary to provide a slip for the sewing machine. The moving member can reliably prevent long-term abrasion and seizure of the sliding part without supplying a lubricating oil, and the sewing machine using the sliding member. — — — — — — — — — — — — I ·-III — I i I 111111 See (please read the notes on the back before filling this page)

Description of the invention (9) It has a better effect on abrasion. At least the sliding surface 21 should preferably be formed of a copper-based alloy or cast alloy to enhance the abrasion resistance and durability during sliding in a non-lubricated state. The needle bar bearing 15 may have at least one portion constituting the slidable surface 21 formed of copper and alloys mainly composed of alloys and front alloys, and the other portions may be made of a less expensive metal material. For the fat and oil G of this embodiment, a fat and oil mainly composed of a paraffin can be used. According to the present embodiment, the poly-α-olefin-based oil and fat is composed of 85 to 90% by weight of a poly (2-olefin-based lubricant oil as a base oil, and a soap as a thickener to have a consistency of 310 to 340 (consistency (cone Body penetration) No · 1) consistency (cone penetration). If the content and consistency (cone penetration) of the main poly-olefin oil is less than the above range, the grease The gap (not shown) between the sliding surface 20 and the sliding surface 21 and the extremely small recessed portion 23 flows down and leaks out. If it is larger than this range, the grease G is liable to stick to the sliding surface 20 and the sliding surface 20 The gap between the faces 21 makes it impossible to form a proper lubricating film. In addition, the grease G having this structure has a milky color and can be used in a temperature range of -40 to 150 ° C. Although in this embodiment, The extremely small recessed portion 23 is formed on the sliding surface 20 and the grease holding portion 28 is formed on the slidable surface 21, however, the grease holding portion 28 may be formed on the sliding surface 20 and the extremely small recessed portion 23 It is formed on the slidable surface 21. More specifically, it is desirable that the extremely small recessed portion 23 is formed on the The grease holding portion 28 for holding the grease g on one of the sliding surface 20 and the to-be-slided surface 21 needs to be formed on the other, depending on the size of the slider and the support.

Invention Description (10) Rod 11) The sliding surface 20 is used to strengthen the holding property of the grease G without destroying the strength of the sliding member. In addition, when the needle bar is surrounded by the bearing, it will be difficult to form the extremely small recess on the sliding surface inside the bearing. Therefore, the extremely small recess should be formed on the needle bar to enhance its workability. The other structures are the same as those of the conventional sewing machine, so detailed descriptions are omitted. Next, the functions of the embodiment having the above-mentioned configuration will be described in detail later. According to the embodiment of the sliding member 10 for a sewing machine in the needle bar 11 and the needle bar bearing 15 of the sewing machine μ, the extremely small recess 23 is formed on the sliding surface 20 of the needle bar 11. Therefore, the surface area of the sliding surface 20 can be increased and the grease can be held. Therefore, the grease G can be subjected to the extremely small recess 23 provided on the needle bar π sliding surface 20 and the sliding surface 21 of the needle bar bearing 15 Both the grease holding portions 28 are held. Thereby, the initial filling amount can be easily maintained to provide the supporting amount of grease G required to reliably prevent the abrasion and gluing hazards of the sliding part until the end of the life of the sewing machine. In addition, according to the present embodiment, in the sliding member 10 of the sewing machine M used in a sewing machine, the content of the polyalphaolefin-based lubricant is set to 85 to 90% by weight. Therefore, the lubricating film can be formed between the sliding surface 20 and the sliding surface 21 to reduce the friction resistance, thereby preventing the sliding part from being worn and stuck. In addition, the chain soap is used as a thickening agent to have a consistency (cone penetration) of 31 to 340. Therefore, the grease 0 can be prevented from flowing down from the gap between the sliding surface 20, the sliding surface 21, and the extremely small recessed portion 23. Therefore, even if the grease G is not supplied, the lubricating film can be held for a long time. In addition, the grease G is prevented from flowing down. Therefore, it can also prevent a sewn object from being contaminated due to leakage of conventional lubricating oil and prevent the working environment from being subject to -13- --------- g ----- 7I1T ------ 0 (Please read the precautions on the back before filling out this page) This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Invention Description (U) damage.拫 According to the present embodiment, the grease G in the sliding member 10 of the sewing machine M in a sewing machine has a translucent (creamy) color. Even if the grease G flows down and contaminates the object to be sewn, it does not cause a large stain. In addition, when the sewn object is washed, its color does not remain. Therefore, the appearance of the sewn object can be maintained with high quality. In addition, a falex test can be used to evaluate one of the characteristics according to the present embodiment. Therefore, a gluing load is about 8 lbs. And higher than other types of grease. For example, Molecoat ϋ paste (trade name made by Dow Coning Co., Ltd .: USA) has a glue load of about 400 pounds, and Molecoat EM-40M (by Dow Coning Co., Ltd. Trademark names manufactured by USA) and juk〇731 (trade name manufactured by juk〇Lubricant Co., Ltd.) have a glue holding force of approximately 600 pounds. The foregoing points out that the grease G is particularly effective in durability against a sliding portion subjected to a high load (high surface pressure) in an oil-free supply state, such as a sliding portion of a needle bar of a needle swing sewing machine, and A group of upper and lower needle bar bearings on the needle bar supporting platform of the needle bar are rotatably supported and pushed. Therefore, according to this embodiment, the sliding member 10 for a sewing machine M in a sewing machine can reliably prevent abrasion and seizure of the sliding portion for a long time without oil supply. Further, according to this embodiment, the sliding member 10 for the sewing machine M in a sewing machine can easily obtain the highest degree of durability of the sliding portion of the needle bar 11 and the needle bar bearing 15 without oil supply. In addition, according to this embodiment, the sewing machine M does not require a strong supply of lubricating oil. 14 · This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ---- ^ ---- " --- 1Τ ------ 0 (Please read the precautions on this page and then fill out this page) 493019 A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 1. · V. Invention Description (U) The needle bar 11 and A sliding portion between the needle bar bearings 15. Therefore, it is possible to remove the oil reservoir and the oil supply pipe as the oil supply that require a strong oil supply. In this way, the number of components and assembly steps of the sewing machine can be reduced. Thereby, the total cost of the sewing machine M can be easily reduced. In addition, according to the sewing machine M of this embodiment, it is not necessary to forcefully supply lubricating oil to the sliding portion between the needle bar 11 and the needle bar bearing 15. Therefore, it is also possible to dispense with the lack of supply of different lubricating oils or lubricating oils with different functions, such as cooking oil, during the supply of lubricating oil when using conventional powerful oil supplies. For the durability of the sliding member for a sewing machine according to the present invention, the third circle shows the results of the evaluation of the relationship between the backlash of a needle bar and the durability time in a needle swing sewing machine. This durability was evaluated by using a conventional needle swing sewing machine as a testing machine and combining the sliding member for a sewing machine according to the present invention as a testing machine, thereby conducting a test (a real machine test). In more detail, as shown in FIG. 4 (a), the sliding member for a sewing machine according to the present invention is used for a sliding portion of a needle bar 11A and a pair of upper and lower needle bar bearings provided on a needle bar supporting table 31 15A supports the needle bar 11A in a swinging manner. Accordingly, the extremely small recess (not shown), which is the same as the extremely small recess 23 in the second frame, is provided on the sliding surface. The sliding surface is not shown in the figure, which is the needle bar 11A in the fourth circle. On the outer peripheral surface, the oil supporting portion (not shown), which is the same as the grease holding portion 28 in FIG. 2, is formed on a moving surface, and the sliding surface is not shown.

The lower part of 11A and the circle are not shown in a lateral direction (needle swing direction). This evaluation is performed by measuring the backlash of the needle bar n in an oil-free supply state, that is, the needle bar 11A passes through a needle bar UA and the two needle bar bearings 15A (15Aa, 15Ab) The amount of movement of the gap, and the passage time when the needle swing sewing machine (not shown) is driven at 4,000 rpm and the needle bar UA is rocked. In the third circle, a transverse backlash and the backlash amount described above and shown by the solid line indicate the tooth stale amount when the needle bar is moved to the left in the needle swing direction. In Fig. 3 ', the backlash amount and the backlash amount indicated by the dashed line indicate the backlash amount when the needle bar is moved to the left in a direction orthogonal to the direction of the needle movement. It is clear from the test results that it can be determined that the increase in backlash of the needle bar 11A is 0.02 mm or less, which is almost constant and does not exceed the backlash amount limit of 012_, so that if it is durable When the time is 10,000 hours or less, practical problems will not occur. The endurance time of 300 hours in the actual machine test corresponds to the time required for the sewing machine to be used for one year. Therefore, a durability of 1,000 hours is equivalent to 3 years of use of the sewing machine. In other words, it is easy to guarantee the basic use of the sewing machine without oil supply for 3 years or more. Therefore, according to the present invention, it can be confirmed that by using the oil-free supply for 3 years as the durable life of the sewing machine, the abrasion and gluing hazard of the sliding portion between the needle bar 11A and the needle bar bearing 15A can be reliably prevented. -16- This paper size applies to Chinese National Standard (CNS) A4 specification (210X297 male diamond) Packing ^^-I—1T ------ 0 (Wu Xian first read the precautions on t side and fill out this page ) Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _____B7 V.
