As shown in Figures 1-4, a double speed chain sleeve structure includes an inner link plate 1. Both ends of one side of the inner link plate 1 are fixedly connected with pins 2, and the other end of the pin 2 is provided with a pin 2 inside. The outer surface of the other end of the pin 2 is fixedly connected to the outer link plate 3, and is fixed with the inner link plate 1 through the removable locking piece in the internal fixing hole of the pin 2. The pins at both ends of the inner link plate 1 The outer surface of the shaft 2 is movably sleeved with a sleeve member 6. The outer surface of the sleeve member 6 is movably sleeved with a roller assembly 5. The outer surface of the roller assembly 5 is movably sleeved with a roller 4; the roller 4 includes a wheel body. 41. Rotation holes 42 are provided on both sides of the wheel body 41. A socket hole 43 corresponding to the roller assembly 5 is provided inside the wheel body 41. Balls 44 are rotatably installed inside the socket hole 43. The balls 44 are The number is several; the roller assembly 5 includes a right inlay block 51 and a left fixed block 52. One side of the right inlay block 51 is fixedly connected with a roller bushing 54, and the side of the roller bushing 54 is fixedly connected with a fixed block. The head 55 and the other side of the right embedded block 51 are fixedly connected with a roller tube 56. An oil inlet hole 57 is provided inside the roller tube 56. By setting the ball 44 inside the socket hole 43, between the wheel body 41 and the roller When the surfaces of the shaft sleeve 54 rotate relative to each other, sliding friction replaces rolling friction, thereby reducing friction, improving the transmission efficiency of the double-speed chain, and also reducing the noise generated during the transmission process.

Among them, the left fixing block 52 is provided with a fitting sleeve hole 53 on one side, and the fitting sleeve hole 53 is fitted on the outer surface of the fixed head 55. The size of the left fixing block 52 is the same as that of the right fitting block 51, and They are all embedded and installed inside the rotation holes 42 on both sides of the wheel body 41. The roller sleeves 54 are movably connected inside the sleeve holes 43, and the roller sleeves 54 are movably installed on the outer surface of the balls 44.

Among them, the right embedded block 51 , the roller tube 56 and the roller bushing 54 are all provided with communication holes 58 inside. One end of the communication hole 58 is fixedly connected with the oil inlet hole 57 inside the roller tube 56 , and the communication hole 58 A number of flow holes 59 are provided at the bottom. The communication holes 58 are fixedly connected to the sleeve member 6 through the flow holes 59. The communication holes 58 are inclined, and one end of the roller tube 56 is higher than the other end of the roller sleeve 54. When When lubricating oil is applied to the oil inlet hole 57 , the lubricating oil passes through the inclined shape of the communication hole 58 and is affected by gravity and flows to the bottom, so that the lubricating oil can be applied to the inside of the sleeve member 6 .

As shown in Figures 5-6, the sleeve member 6 includes a sleeve body 61. The outer surface of the sleeve body 61 is provided with a number of embedding grooves 62. The positions of the several embedding grooves 62 are respectively connected with the roller sleeve 54. The inner flow hole 59 corresponds.

Among them, the outer surface of the embedding groove 62 is movably connected with oil-absorbing cotton 64, and the bottom of the embedding groove 62 is provided with several oil outlets 63. The oil-absorbing cotton 64 is used to store and transfer the lubricating oil accordingly, so as to avoid lubricating oil. It passes through the oil outlet hole 63 at one time and flows into the surface of the pin 2, causing the lubricating oil to be lost too quickly. In addition, since the main component of the oil-absorbing cotton 64 is fiber, the fiber is a natural organic polymer compound, and the fiber is interlaced in a network shape. , there are many gaps in between, and the lubricating oil can produce capillary phenomenon through these gaps, which not only absorbs the lubricating oil, but also spreads evenly into the inside of the oil-absorbing cotton 64.

Among them, the sleeve body 61 is made of alloy carburized steel, and the surface of the sleeve body 61 is coated with a wear-resistant ceramic coating. The surface of the wear-resistant ceramic coating is provided with a titanium carbide layer and an ultra-fine alloy layer, making the sleeve body 61 is not only wear-resistant, but also has high strength and hardness.

The sleeve body 61 and the sealing collar 65 are both movably sleeved on the outer surface of the pin shaft 2. The sleeve body 61 is in fixed communication with the inside of the right embedding block 51 through the oil outlet hole 63 .

The working principle of the present invention: during use, when the rotation effect of the roller 4 is not ideal or the rotation difficulty occurs after long-term use, lubricating oil can be applied directly through the surface of the roller tube 56 on the side of the wheel body 41, and the lubricating oil passes through the inlet. The oil hole 57 enters the interior of the communication hole 58 and flows into the surface of the sleeve body 61 through the flow hole 59. At this time, since the position of the flow hole 59 is opposite to the position of the oil-absorbing cotton 64, the lubricating oil enters the oil-absorbing cotton 64. On the surface of the cotton 64, the capillary phenomenon generated by the oil-absorbing cotton 64 not only absorbs the lubricating oil, but also diffuses it evenly into the inside of the oil-absorbing cotton 64, automatically lubricating the inside of the sleeve body 61 and the roller sleeve 54;

In addition, the lubricating oil enters between the sleeve body 61 and the pin 2 through the oil outlet hole 63 to lubricate the interior. The use of the oil-absorbing cotton 64 not only makes the internal lubrication more uniform, but also makes the lubrication more sufficient. Therefore, comprehensive lubrication can be achieved without disassembly, and the sealing collar 65 is used to reduce the loss of lubricating oil. At the same time, it blocks dust in the air and reduces the impact of air dust on the sleeve body 61 and the pin 2 and Effect of friction between rollers 4.
