Description

Technical Field

[0001] The utility model relates to the field of gears, in particular to a novel output gear structure. Background Art

[0002] The output gear is a key component in a mechanical transmission system. It is usually located at the end of the transmission chain and is used to transmit power or torque to the final working part or mechanism. In many mechanical equipment, such as automobiles, machine tools, wind turbines, etc., output gears play a vital role. Output gears can be divided into many types according to their design, purpose and working environment, including but not limited to: spur gears, helical gears, bevel gears, planetary gears, etc. When the gears are in use, if they are subjected to large loads or run at high speeds, the teeth will easily wear or even break. Since traditional gears are often an integrated structure, if the worn or broken teeth need to be replaced, the gears need to be replaced as a whole. However, replacing the gears as a whole will result in a certain waste of resources and will also increase the maintenance cost. Therefore, a new output gear structure is needed to solve the above problems. Utility Model Content

[0018] 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.

[0019] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, a new output gear structure includes a gear hub 1 and gear teeth 2. There are several gear teeth 2 and they are all inserted into the gear hub 1. The gear teeth 2 are composed of a gear tooth body 7 and a T-shaped mounting bar 8. The T-shaped mounting bar 8 is fixedly mounted on the inner end of the gear tooth body 7. Two limiting structures 3 are installed on the gear hub 1 and on both sides of the several gear teeth 2. The limiting structure 3 is composed of an annular baffle 9, a first connecting ring 10 and a second connecting ring 12. The first connecting ring 10 is fixedly mounted on the inner wall of the annular baffle 9. The second connecting ring 12 is fixedly mounted on the inner end of the first connecting ring 10, and the connecting shaft 4 is inserted into the gear hub 1. When the gear runs at high speed or the gear teeth 2 are subjected to a large load, the gear teeth 2 will easily wear or break. When the gear teeth 2 are worn or broken, the worn or broken gear teeth 2 can be replaced separately. The method is to first rotate the limiting structure 3 on the gear hub 1 by a certain angle so that the T-shaped through groove 11 is aligned with the T-shaped mounting slot 14. At this time, the gear teeth 2 are fixed. The gear teeth 2 are released, and then the worn or broken gear teeth 2 can be pushed along the T-shaped mounting slot 14, so that the T-shaped mounting strip 8 passes through the T-shaped slot 11 and is completely removed from the T-shaped mounting slot 14. At this time, the gear teeth 2 are disassembled, and then the new gear teeth 2 can be installed on the gear hub 1. At this time, the T-shaped mounting strip 8 must be fully inserted into the T-shaped slot 14 through the T-shaped slot 11. Finally, the limiting structure 3 is rotated on the gear hub 1 at an angle so that the T-shaped slot 11 and the gear hub 1 are aligned. The T-shaped mounting slots 14 are staggered, and the gear teeth 2 are fixed at this time, and the replacement of the gear teeth 2 is finally completed. By providing a gear composed of a detachable gear hub 1 and gear teeth 2, the worn or broken gear teeth 2 can be replaced separately without replacing the gear hub 1 together, thereby reducing the waste of resources and reducing maintenance costs. By providing a limiting structure 3, the disassembly and assembly of the gear teeth 2 and the gear hub 1 can be facilitated, thereby facilitating the replacement of the gear teeth 2.

[0020] Furthermore, two annular receiving grooves 5 are symmetrically provided at both ends of the gear hub 1, and four mounting screw holes 6 are symmetrically provided on the inner wall of the annular receiving groove 5. A plurality of T-shaped mounting slots 14 are provided on the outer wall of the gear hub 1. The plurality of T-shaped mounting slots 14 are distributed in a ring shape, and the plurality of T-shaped mounting slots 14 all pass through the gear hub 1. The T-shaped mounting strip 8 on the gear teeth 2 is inserted into the T-shaped mounting slot 14 provided on the outer wall of the gear hub 1, and the gear tooth body 7 is tightly attached to the outer wall of the gear hub 1. When the gear teeth 2 need to be removed from the gear hub 1, the T-shaped mounting strip 8 on the gear teeth 2 can be pulled out from the T-shaped mounting slot 14 provided on the gear hub 1. Conversely, when the gear teeth 2 need to be installed on the gear hub 1, the T-shaped mounting strip 8 needs to be inserted into the T-shaped mounting slot 14.

[0021] Furthermore, the annular baffle 9 on the limiting structure 3 is tightly attached to one end of the gear hub 1, and the first connecting ring 10 and the second connecting ring 12 are both located in the annular receiving groove 5. A plurality of T-shaped through grooves 11 are provided on the outer wall of the annular baffle 9 on the limiting structure 3. The plurality of T-shaped through grooves 11 are distributed in an annular pattern, and the plurality of T-shaped through grooves 11 pass through the annular baffle 9. Four arc-shaped guide grooves 13 are symmetrically provided on the second connecting ring 12. The four arc-shaped guide grooves 13 pass through the second connecting ring 12, and the second connecting ring 12 can be fixedly connected to the gear hub 1 by bolts. The bolts for fixing the second connecting ring 12 on the gear hub 1 are provided from the arc grooves provided on the second connecting ring 12. shaped guide groove 13, and then screwed into the mounting screw hole 6. When it is necessary to rotate the limiting structure 3 to complete the fixation of the gear teeth 2 or release the fixation of the gear teeth 2, the bolt used to fix the second connecting ring 12 can be loosened first, so that the head of the bolt does not contact the second connecting ring 12. At this time, it contacts the fixation of the limiting structure 3, and then the limiting structure 3 can be rotated. When the limiting structure 3 needs to be fixed, the bolt can be tightened so that the head of the bolt presses the second connecting ring 12 onto the gear hub 1; the size of the T-shaped through slot 11 needs to be the same as the T-shaped mounting slot 14, so as to ensure that the T-shaped mounting bar 8 can smoothly pass through the T-shaped through slot 11.
