Abstract
Description
Technical Field
[0001] This utility model relates to the field of bevel gear technology, specifically to bevel gears used in gearboxes. Background Technology
[0002] Bevel gears, also known as bevel gears, are used to transmit motion and power between two intersecting shafts. Bevel gears are widely used in mechanical engineering, including industrial transmission equipment, vehicle differentials, locomotives, ships, power plants, steel mills, and railway track inspection. Existing bevel gears used in gearboxes, after long-term transmission, will cause friction between the two bevel gears, resulting in wear, loose meshing, gaps, and loosening. To address the above problems, this application designs a bevel gear for gearboxes. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] In view of the shortcomings of the prior art, this utility model provides a bevel gear for a gearbox.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bevel gear for a gearbox, comprising a mounting post and a gear body, wherein a limit post is fixed on the mounting post, a spring block is fixed on the outer wall of the limit post, a locking ring is slidably connected to the outer wall of the limit post, a first spring is sleeved on the outer wall of the limit post, the two ends of the first spring are respectively fixed to the locking ring and the spring block, a plurality of positioning posts are fixed on the locking ring, an adjusting block is rotatably connected to the outer wall of the limit post, a plurality of positioning grooves adapted to the positioning posts are opened on the adjusting block, and a thread is provided on the adjusting block, an adjusting post is fixed on the gear body, the adjusting post is threadedly connected to the adjusting block, a limit rod is fixed on the gear body inside the adjusting post, and the limit rod is slidably connected to the limit post.
[0007] Furthermore, the present invention is improved in that the limiting post is configured in a cross shape, and the limiting rod is adapted to the limiting post.
[0008] Furthermore, an improvement of this utility model is that an anti-slip groove is provided on the outer wall of the adjusting block.
[0009] Furthermore, the present invention is improved by providing anti-slip texture on the outer wall of the locking ring.
[0010] Furthermore, an improvement of this invention is that the gear body is provided with an anti-oxidation coating.
[0011] (III) Beneficial Effects
[0012] Compared with the prior art, the present invention provides a bevel gear for a gearbox, which has the following advantages:
[0013] The bevel gear used in the gearbox is equipped with an adjusting block that is threadedly connected to an adjusting column. When the gear body rotates for a long time and wears out, the locking ring is pulled to disengage the positioning column from the positioning groove. Rotating the adjusting block causes the adjusting column, which is threaded onto the adjusting block, to move the gear body outward. Because the bevel gear is tapered, it moves outward toward another meshing bevel gear. The two inclined surfaces get closer and closer, bringing the tooth edges closer together and reducing the wobbling caused by wear-induced gaps. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4A bevel gear for a gearbox includes a mounting post 1 and a gear body 2. A limit post 3 is fixed on the mounting post 1. A spring block 4 is fixed on the outer wall of the limit post 3. A locking ring 5 is slidably connected to the outer wall of the limit post 3. A first spring 6 is sleeved on the outer wall of the limit post 3. The two ends of the first spring 6 are respectively fixed to the locking ring 5 and the spring block 4. A plurality of positioning posts 7 are fixed on the locking ring 5. An adjusting block 8 is rotatably connected to the outer wall of the limit post 3. A plurality of positioning grooves 9 adapted to the positioning posts 7 are opened on the adjusting block 8. The adjusting block 8 is provided with threads. An adjusting post 10 is fixed on the gear body 2. The adjusting post 10 is threadedly connected to the adjusting block 8. A limit rod 11 is fixed on the gear body 2 inside the adjusting post 10. The limit rod 11 is slidably connected to the limit post 3.
[0021] When this bevel gear is in use, after prolonged meshing and rotation, wear occurs. First, pull the retaining ring 5 backward, causing the positioning pin 7 to disengage from the positioning groove 9. At this time, the first spring 6 is stretched. Then, rotate the adjusting block 8, causing the adjusting pin 10, which is threaded onto the adjusting block 8, to move the gear body 2 outward. Simultaneously, the limiting rod 11 slides relative to the limiting pin 3, releasing the retaining ring 5. The first spring 6 releases its potential energy, causing the retaining ring 5 to move towards the adjusting block 8. The retaining ring 5 then causes the positioning pin 7 to insert into the positioning groove 9, thus fixing the adjusting block 8 and preventing its rotation. As the gear body 2 moves outward, since the gear body 2 is cone-shaped, it continuously approaches another meshing bevel gear, bringing the two inclined surfaces closer together. This allows the tooth edges on the gear body 2 to come closer together, reducing gaps and wobbling.
[0022] Furthermore, in this embodiment, the limiting post 3 is configured in a cross shape, and the limiting rod 11 is adapted to the limiting post 3.
[0023] In actual use, it was found that slippage would occur when rotating the adjusting block 8. In order to avoid the above problem, in this embodiment, the outer wall of the adjusting block 8 is provided with an anti-slip groove.
[0024] In actual use, it was found that slippage would occur when the locking ring 5 was pulled. In order to avoid the above problem, in this embodiment, the outer wall of the locking ring 5 is provided with anti-slip texture.
[0025] Furthermore, in order to extend the service life, in this embodiment, the gear body 2 is provided with an anti-oxidation coating.
