Description

412624 V. Description of the invention (1) The present invention relates to a chain with a well-designed chain and a long service life. As shown in the current schematic diagrams of various conventional mechanical chains that are still assisted by chains, the conventional chains are assembled in series, and each parallel-arranged roller 12 of the chain 1 is located on 2 Do not wear a bushing is placed on the shaft of the roller 1, 2, the inner sheet 1 3, and extending to the inner sheet 13 to the outer sheet 1 3 and the outer sheet 16 and other structures; 14 and the outer sheet 16 and The pivot joints of the shaft 14 are far away from the openings 1 3 1, 1 and 61 are available for the shaft to penetrate the inner and outer pieces 1 of the unit 11, and 3, 6. The pivot 1 is set because the material of the chain 1 is mostly solid and resistant to gold. The pull mechanism is convenient, but the mechanical device is used. However, the chain 1 made of metal causes the lack of lubricating oil to cause the smooth operation during transmission to avoid rust. When it is used, the transmission can be smoother. The conventional key bar 1 is described in practical terms, and particularly refers to a dust-proof mechanically-equipped drive mold bar 1 system—a key roller 12 rod 14 and a frame frame therein, and an open position 14 is provided. It belongs to the movement between the use of life, outside, and the same type of transmission, the main type; please refer to the first picture by the majority of the key and head unit 1 1 unit 11 is composed of two inner sides 1 3, points- Set on the shafts 14 and each shaft 14 to protrude these inner pieces 13 and shaft openings 131 > 161, and at the same time, each chain element 'uses the power to improve the use of the transmission can be smooth and real-time' as Avoid rusting and ensure that the chain 1 can be ensured when it is coated on the key 1. The foreign description is as follows: There are still some defects in use. The dust resistance is not good: As the chain 1 is known, each chain cup 14 and the outer piece The inner piece 13 and the shaft contact in the pivot unit 11 of the 6 and the shaft 1 4 are exposed to the outside, and each

Therefore, these inner and outer pieces 1 3 There will be a gap between the 16 and the shaft 14 to some extent, and at the same time, because the inner and outer pieces 1 3, 16 and the shaft 14 are not covered, the inner and outer pieces 13 and the shaft are coated. The lubricating oil on the rod 14 and the outer plate 16 and the shaft rod 14 will be directly opened in the air. At this time, the dust or suspended particles contained in the air in the workplace will easily stick to the inner plate 1 3 The joints between the shaft 14 and the outer plate 16 and the shaft 14 cause the chain 1 to be susceptible to such suspended particles or dust during operation, which causes a friction phenomenon at the joint. ) If the wear phenomenon continues to occur, the chain 1 will be damaged. 2 · Lubrication is incomplete: Because the chain 1 needs to be placed between the two mechanical devices with a very appropriate size and length, this can prevent the key bar 1 from being placed between the mechanical devices, resulting in improper operation. The lack of smoothness is caused by the fact that when the conventional key bar 1 is in operation, the pulling phenomenon of each chain element unit i 1 is bound to become more severe. At this time, it exists in the inner plate 13 and the shaft i 4 and the outer plate. The lubricating oil at the pivotal joint of 16 and the shaft 14 will be released by the compression of the inner and outer sheets 13, 16 at the same time, because the lubricating oil is liquid and volatile, making the chain > When moving, the squeezed lubricating oil will naturally volatilize and disappear, and then, it will be replenished to its pivot joint, which will cause the chain ^ to drive, ^ = dry grinding phenomenon, so go further Reduce the life of the conventional chain 1 a. Flying • Easily Damaged ::
