DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-5 The present invention provides a technical solution for a carburized gear-grinding drum transmission device:

[0027] according to Figure 1-Figure 5 As shown, it includes a driving sleeve 1 and a driven sleeve 10, and the driven sleeve 10 is placed on one side of the driving sleeve 1. The outside of the driving sleeve 1 and the outside of the driven sleeve 10 are both sleeved with sleeves 3, and the inner walls of the two sleeves 3 are fixedly provided with outer gear rings 13. The middle part of the outer wall of the driving sleeve 1 and the middle part of the outer wall of the driven sleeve 10 are fixedly embedded with gear cylinders 11, and the outer walls of the two gear cylinders 11 are fixedly provided with inner gear rings 12, and the inner gear rings 12 are meshed and connected with the outer gear rings 13. One end of the two sleeves 3 is fixedly connected with an end ring 2, and a plurality of air ducts 14 are excavated on the two end rings 2. The air ducts 14 here are arranged obliquely, and the air inlet angle of the air ducts 14 can be adjusted so that the wind direction blows toward the plurality of mesh cylinders 24, so that the blown particles will be blown into the mesh. In the cylinder 24, the middle parts of the outer walls of the two sleeves 3 are fixedly connected with a connecting cover 4, and the ends of the two connecting covers 4 close to each other are fixedly connected with an annular connecting plate 5, and the outer parts of the two annular connecting plates 5 are clamped and connected with two semicircular clamping plates 6. The two semicircular clamping plates 6 clamp the two annular connecting plates 5 together, reducing the number of bolts, thereby making the disassembly and installation steps more convenient. The inner wall of one of the connecting covers 4 is provided with a plurality of mesh cylinders 24, and the inner walls of one side of the plurality of mesh cylinders 24 are fixedly connected with a magnet block 8, and the fine particles generated by wear are of metal material. The outer walls of the two sleeves 3 are symmetrically fixedly connected with two oil filling pipes 17, and oil filling holes 19 are drilled at the positions corresponding to the positions of the outer walls of the two sleeves 3 and one end of the four oil filling pipes 17.

[0028] Then, one side wall of the two end rings 2 is fixedly connected with multiple arc-shaped nets 9, and the multiple arc-shaped nets 9 are respectively opposite to one end of the multiple air ducts 14. The arc-shaped nets 9 block external foreign matter to prevent foreign matter from entering and blocking the air ducts 14. The inner walls of the two end rings 2 are both opened with grooves, and one side of the outer wall of the active shaft sleeve 1 and one side of the outer wall of the driven shaft sleeve 10 are both fixedly connected with a clamping ring 15. The two clamping rings 15 are respectively engaged with the two grooves to achieve limiting. Both ends of the two semicircular clamping plates 6 are fixedly connected with mounting plates 7, and the two opposite mounting plates 7 are fixedly connected by bolts.

[0029] In addition, a plurality of inner plates 20 are fixedly connected to the inner wall of one of the connecting covers 4, and a compression spring 21 is fixedly connected to one side wall of the plurality of inner plates 20. When the plurality of net tubes 24 are fixed inside the connecting cover 4, the compression spring 21 is squeezed. When the two connecting covers 4 are separated, the elastic force of the compression spring 21 pushes the net tube 24 so that the net tube 24 moves out of the bottom of the connecting cover 4 and is exposed, so as to facilitate the cleaning of the collected particles. A plurality of compression springs 21 are fixedly connected to a connecting rod 23 at one end away from the inner plate 20, and one end of the plurality of connecting rods 23 is respectively fixedly connected to the center of one end of the plurality of net tubes 24. A plurality of top rods 22 are fixedly connected to the inner wall of another connecting cover 4. When the net tube 24 is fixed inside the connecting cover 4, the net tube 24 is supported to increase its stability. One end of the plurality of top rods 22 is respectively contacted and connected with the center of the other end of the plurality of net tubes 24.

[0030] Finally, oil channels 16 are excavated inside the four oil filling pipes 17. The middle part of the oil filling pipe 17 is bent, so that the flow path of the lubricating oil is bent. This prevents the centrifugal force from causing the injected lubricating oil to flow back out of the oil channel 16 when the device rotates. The middle part of the four oil channels 16 is fixedly connected with a filter element 18 to filter the injected lubricating oil. The oil channel 16 is connected to the inside of the oil filling hole 19.

[0031] In specific use, the present invention is a carburized and ground gear drum transmission device and a transmission method thereof. The operator can fix the driving shaft and the driven shaft to the driving sleeve 1 and the driven sleeve 10 respectively. When the driving shaft rotates, the driving sleeve 1 is first driven to rotate, and the inner gear ring 12 on the driving sleeve 1 is meshed with the outer gear ring 13 at the corresponding position, thereby driving the rotation of the sleeve 3. The rotating sleeve 3 drives the rotation of the driven sleeve 10 through another outer gear ring 13, so that the driven shaft placed inside the driven sleeve 10 realizes transmission. After the device has been used for a period of time, the inner gear ring 12 and the outer gear ring 13 will be worn to a certain extent, generating tiny particles. These tiny particles are thrown away due to centrifugal force, and cooperate with the oblique wind entering from multiple air ducts 14, so that the tiny particles pass through multiple meshes. The cylinder 24 is adsorbed by the magnet block 8 in the mesh cylinder 24, and the magnet block 8 collects these tiny metal particles inside the mesh cylinder 24, reducing the impact of the particles on the inner gear ring 12 and the outer gear ring 13. When oiling is needed, lubricating oil can be injected into the oil passages 16 of the four oil filling pipes 17 respectively. The lubricating oil flows along the oil passages 16, and is gradually filtered by the filter element 18 therein and enters the inner gear ring 12 and the outer gear ring 13 for lubrication. When it is necessary to disassemble for maintenance, first remove the two bolts, so that the two semicircular clamping plates 6 can be removed, the two annular connecting plates 5 are separated, and after one of the connecting covers 4 is removed, the multiple push rods 22 no longer hold the multiple mesh cylinders 24, so that the elastic force of the multiple compression springs 21 pushes the multiple mesh cylinders 24 to move and expose them.
