Description

Technical Field

[0001] This utility model belongs to the field of gear technology, specifically a gear assembly with good stability. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that can continuously mesh to transmit motion and power. Gears are usually fixed on a shaft to rotate. Therefore, the axial and circumferential fixation of the gear on the shaft is particularly important. When the gear cannot be firmly fixed on the shaft, it will cause the gear to move axially and radially, causing vibration during operation, resulting in friction and impact, which reduces the power transmission efficiency and accelerates the damage of the gear. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a gear assembly with good stability to address the above-mentioned defects and solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A gear assembly with good stability includes a shaft and a gear sleeved on the shaft. An annular limiting block is provided on one side of the gear, and rectangular limiting strips are symmetrically provided at both ends of the other side. A limiting step that abuts against the annular limiting block is provided on one side of the outer surface of the shaft. A limiting sleeve that abuts against the side wall of the gear is provided on the other side of the shaft. The side wall of the limiting sleeve is fixedly connected to the shaft by bolts, driving the gear to fit tightly against the limiting step. The limiting sleeve has symmetrically provided mounting grooves at both ends. The rectangular limiting strip has symmetrically provided locking grooves that communicate with the mounting grooves at both ends. A fastening rod is provided inside the mounting groove. One end of the fastening rod is hinged to the bottom end of the inner wall on both sides of the mounting groove. The other end of the fastening rod passes through the mounting groove and the locking groove and extends to the outside of the rectangular limiting strip. A fastening nut that abuts against the rectangular limiting strip is provided on the fastening rod outside the rectangular limiting strip.

[0005] Furthermore, a first mounting hole matching the shaft body is provided at the center of the gear, keyways are provided on both sides of the first mounting hole, and a key block matching the keyway is provided on the outer surface of the shaft body.

[0006] Furthermore, a second mounting hole matching the shaft body is provided on the side of the limiting bushing near the shaft body, and the bolt passes through the limiting bushing and is threaded to the side wall of the shaft body.

[0007] Furthermore, the locking groove is a through structure, the mounting groove and the locking groove are on the same central axis, and the fastening rod outside the rectangular limiting strip is provided with external threads.

[0008] Furthermore, the two ends of the limiting bushing respectively abut against two rectangular limiting strips, and the cross-section of the limiting bushing is a rectangular structure.

[0009] The beneficial effects of this utility model are:

[0010] This utility model utilizes a combination of annular limiting blocks, rectangular limiting strips, limiting steps, limiting bushings, bolts, mounting grooves, locking grooves, fastening rods, and fastening nuts. The limiting bushing is fixedly connected to the shaft body by bolts. The limiting bushing, annular limiting blocks, and limiting steps work together to limit the axial movement of the gear. The fastening rod rotates inside the mounting groove and, through the fastening nut, locks the rectangular limiting strip and the limiting bushing, further limiting the circumferential movement of the gear. This interplay ensures the gear is firmly and stably fixed to the shaft body, preventing loosening during power transmission, resulting in smoother power transmission and extended gear lifespan.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Reference Figure 1-4As shown, the stable gear assembly includes a shaft 1 and a gear 2 sleeved on the shaft 1. A ring-shaped limiting block 3 is provided on one side of the gear 2, and rectangular limiting strips 4 are symmetrically provided at both ends of the other side. A limiting step 5 that abuts against the ring-shaped limiting block 3 is provided on one side of the outer surface of the shaft 1. A limiting sleeve 6 that abuts against the side wall of the gear 2 is provided on the other side of the shaft 1. The side wall of the gear 2 and the side wall of the ring-shaped limiting block 3 abut against the limiting step 5. The limiting sleeve 6 abuts against the side wall of the other side of the gear 2. The limiting sleeve 6 and the limiting step 5 cooperate with each other to restrict the axial movement of the gear 2 on the shaft 1 and form a limit on its axial movement.

[0019] The side wall of the limiting bushing 6 is fixedly connected to the shaft body 1 by bolts 7, causing the drive gear 2 to fit tightly against the limiting step 5. Bolts 7 fix the limiting bushing 6 to the shaft body 1. One end of bolt 7 passes through the center of the limiting bushing 6 and is threaded to the shaft body. The limiting bushing 6 has symmetrically arranged mounting grooves 601 at both ends. The rectangular limiting strip 4 has symmetrically arranged locking grooves 401 at both ends that communicate with the mounting grooves 601. A fastening rod 8 is arranged inside the mounting groove 601. One end of the fastening rod 8 is hinged to the bottom end of the inner wall on both sides of the mounting groove 601. The other end of the fastening rod 8 passes through the mounting groove 601 and the locking groove 401, extending to the outside of the rectangular limiting strip 4. The fastening rod 8 outside the rectangular limiting strip 4 is provided with... A fastening nut 9 is placed to abut against the rectangular limiting strip 4. The fastening rod 8 rotates 90° inside the mounting groove 601, driving the other end of the fastening rod 8 to enter the locking groove 401 by flipping. The fastening nut 9 fixes the fastening rod 8 to the locking groove 401, forming a lock between the limiting sleeve 6 and the rectangular limiting strip 4, and also between the limiting sleeve 6 and the shaft 1. This improves the overall integrity between the limiting sleeve 6, the shaft 1, and the gear 2, restricting the gear 2 from rotating circumferentially on the shaft 1. Their mutual cooperation ensures that the gear is firmly and stably fixed on the shaft, preventing the gear from loosening during power transmission, making power transmission smoother, and improving the service life of the gear.

[0020] A first mounting hole 201 matching the shaft 1 is provided at the center of the gear 2. The gear 2 is engaged with the shaft 1 through the first mounting hole 201. Keyways 202 are provided on both sides of the first mounting hole 201. A key block 101 matching the keyway 202 is provided on the outer surface of the shaft 1. The key block 101 cooperates with the keyway 202 to further restrict the rotation of the gear 2 in the circumferential direction on the shaft 1, making the installation of the gear 2 and the shaft 1 more secure and stable.

[0021] The limiting bushing 6 has a second mounting hole 602 that matches the shaft 1 on the side near the shaft 1. The bolt 7 passes through the limiting bushing 6 and is threaded to the side wall of the shaft 1. The side end of the shaft 1 enters the second mounting hole 602 of the limiting bushing 6.

[0022] The locking groove is a through structure. The mounting groove 601 and the locking groove 401 are on the same central axis. The fastening rod 8 outside the rectangular limit bar 4 is provided with external threads. The fastening nut 9 is threadedly connected to the external threads on the fastening rod 8.

[0023] The two ends of the limiting bushing 6 abut against the two rectangular limiting strips 4 respectively. The cross-section of the limiting bushing 6 is rectangular. Its rectangular structure cooperates with the rectangular limiting strips 4, so that the limiting bushing 6 cannot rotate on the shaft 1, making the connection of the limiting bushing 6 more firm and stable, and can effectively limit the gear 2.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
