Description

Technical Field

[0001] The utility model relates to the field of gears, in particular to a multi-layer gear. Background Art

[0002] A gear is a mechanical component with teeth on its rim that continuously mesh to transmit motion and power. It transmits power and speed through the meshing of two or more teeth. Each gear has a central axis, and meshing occurs between these two axes. When one gear rotates, the meshing of its teeth drives the other gear, thus transmitting power.

[0003] In the existing patent application with application number CN202021670740.3, a multi-layer gear is proposed. Although it sets the first gear and the second gear as two independent individuals, it can realize the replacement of the first gear or the second gear separately, which solves the current difficulty in integrally molding and casting of multi-layer gears. Once a single tooth surface is damaged, it needs to be replaced as a whole. However, the disassembly and assembly steps of the first gear and the second gear are relatively cumbersome. When assembling the first gear and the second gear or lowering the first gear and the second gear for disassembly, it is necessary to use tools to turn multiple fastening screws one by one, which will make the disassembly and assembly efficiency of the first gear and the second gear low, and then make the efficiency of replacing the first gear or the second gear separately low, so it needs to be improved.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, a multi-layer gear comprises a first gear 1 and a second gear 2, a connecting sleeve 3 is installed in the first gear 1 and the second gear 2, the connecting sleeve 3 is composed of a sleeve body 8 and a U-shaped insert 10, there are two U-shaped inserts 10 and they are symmetrically fixed on the outer wall of the sleeve body 8, four fixing components 4 are movably installed in the connecting sleeve 3, the fixing component 4 is composed of a fixed plug rod 12, a frame baffle 13 and a disassembly spring 14, the frame baffle 13 and the disassembly spring 14 are both sleeved on the fixed plug rod 12, and the frame baffle 13 is located on the inner side of the disassembly spring 14, the fixed plug rod 12 can be inserted in the first gear 1 and the second gear 2, and two are symmetrically installed in the connecting sleeve 3. The limiting plate 5 is located on the inner side of the fixing assembly 4. A circular hole 6 and two connecting grooves 16 are provided on the first gear 1 and the second gear 2. The connecting grooves 16 are connected to the circular hole 6. A blind hole 7 is provided on the inner wall of the connecting groove 16. When the first gear 1 or the second gear 2 is damaged and the first gear 1 or the second gear 2 needs to be replaced separately, the first gear 1 and the second gear 2 can be disassembled. The method is to first push the limiting plate 5 to push it out of the installation groove 9. During this process, the fixing rod 12 on the fixing assembly 4 will first be passively moved out of the arc groove 15. When the limiting plate 5 is moved out of the installation groove 9, the limiting plate 5 is lost. The blocked fixing rod 12 will be pushed by the disassembly spring 14, so that the fixing rod 12 will eventually contact the inner wall of the mounting groove 9. At this time, the fixing rod 12 will be moved out of the blind hole 7, and the fixation of the first gear 1 and the second gear 2 will be released. Then the first gear 1 or the second gear 2 can be removed from the connecting sleeve 3, and then the new first gear 1 or the second gear 2 can be fitted onto the connecting sleeve 3. When the first gear 1 and the second gear 2 are released and the blind hole 7 is aligned with the mounting square hole 11, the limiting plate 5 is inserted into the mounting groove 9. During the process of inserting the limiting plate 5 into the mounting groove 9, the limiting plate 5 will push the fixing rod 12 on the fixing assembly 4 outward. Thereby, the frame-shaped baffle 13 will compress the disassembly spring 14 until the fixed plug rod 12 is in the arc-shaped slot 15. At this time, the fixed plug rod 12 will also be inserted into the blind hole 7. At this time, the first gear 1 and the second gear 2 are assembled and fixed together. By providing the connecting sleeve 3, the fixing component 4 and the limit plate 5, and connecting the first gear 1 and the second gear 2 together by using the connecting sleeve 3, the fixing component 4 and the limit plate 5, the disassembly and assembly steps of the first gear 1 and the second gear 2 can be simpler and more convenient, thereby improving the disassembly and assembly efficiency of the first gear 1 and the second gear 2, and ultimately improving the efficiency of replacing the first gear 1 or the second gear 2 separately.

[0022] Furthermore, the sleeve body 8 on the connecting sleeve 3 is inserted into the circular hole 6 opened on the first gear 1 and the second gear 2, and the U-shaped insert plate 10 is inserted into the connecting groove 16 opened on the first gear 1 and the second gear 2. Two mounting grooves 9 are symmetrically opened on the outer wall of the sleeve body 8 on the connecting sleeve 3. The mounting groove 9 is located on the inner side of the U-shaped insert plate 10, and two mounting square holes 11 are opened on one side wall of the U-shaped insert plate 10. The presence of the connecting sleeve 3 can preliminarily fix the first gear 1 and the second gear 2, so that the first gear 1 and the second gear 2 can rotate synchronously.

[0023] Furthermore, the fixing rod 12 on the fixing assembly 4 passes through the mounting square hole 11 opened on the U-shaped plug-in plate 10, and the fixing rod 12 can be inserted into the blind hole 7 at the same time. The frame baffle 13 is fixedly connected to the fixing rod 12, and the frame baffle 13 and the disassembly spring 14 are both located on the inner side of the U-shaped plug-in plate 10. The limit plate 5 is inserted in the mounting groove 9 opened on the outer wall of the sleeve body 8. One end of the limit plate 5 is symmetrically provided with two arc-shaped slots 15. When the limit plate 5 is pushed, the fixing rod 12 is passively moved out of the arc-shaped slot 15, and the fixing rod 12 and the frame baffle 13 will be pushed outward. At this time, the frame baffle 13 will compress the disassembly spring 14. At the same time, when the limit plate 5 is installed in the mounting groove 9, the limit plate 5 will also push the fixing rod 12 and the frame baffle 13 to When pushed outward, the frame-shaped baffle 13 will still compress the disassembly spring 14. When the fixed rod 12 is passively moved from the end face of the limit plate 5 to the arc-shaped slot 15 as the limit plate 5 moves, the fixed rod 12 will be embedded in the arc-shaped slot 15 under the elastic force of the disassembly spring 14. At the same time, as the limit plate 5 moves, when the limit plate 5 is moved out of the mounting groove 9, the limit plate 5 is lost. The fixed rod 12 and the frame-shaped baffle 13 will be affected by the elastic force of the disassembly spring 14 to move inward. When the fixed rod 12 moves inward, it will slowly move out of the blind hole 7. At this time, the fixation of the first gear 1 and the second gear 2 will be released. When the fixed rod 12 moves outward, the fixed rod 12 can be inserted into the blind hole 7. At this time, the first gear 1 and the second gear 2 can be fixed together.
