Description

Technical Field

[0001] This utility model belongs to the field of automotive parts positioning and clamping technology, and in particular relates to a differential driven gear positioning and clamping device. Background Technology

[0002] A differential is a mechanical device typically used to transmit power to two wheels and enable them to rotate at different speeds. It is commonly used in vehicles, boats, and other machines that need to transmit power to multiple wheels to ensure that the wheels can rotate at different speeds when turning, thereby preventing tire wear and vehicle slippage. The driven gear of the differential is often called the "planetary gear," and it is located in the central part of the differential. It meshes with the sun gear and the ring gear through the planetary gear to achieve different speeds for the two wheels.

[0003] After the driven gear meshes with the other gears of the differential, during long-term high-intensity mechanical transmission, displacement of the driven gear is inevitable. This displacement can lead to damage to the tooth grooves during the rotation of the driven gear, thus affecting its service life. Therefore, it is necessary to clamp and position the driven gear to prevent damage during mechanical transmission. Utility Model Content

[0009] Furthermore, the locking mechanism includes a rotating shaft, a screw, a threaded slider, and a fixing block. Two sets of rotating shafts are symmetrically rotated and installed inside the second mounting housing.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-6 As shown, this utility model is a differential driven gear positioning and clamping device, including a driven gear 1, and further including: an output shaft 2 fixedly connected to one side of the driven gear 1, a bearing 3 fixedly mounted on the surface of the output shaft 2, a mounting housing 4 sleeved on the surface of the bearing 3, a mounting housing 5 slidably connected inside the mounting housing 4, and a locking mechanism provided inside the mounting housing 5. The mounting housing 4 and the mounting housing 5 are fixedly mounted on the bearing 3 by the locking mechanism. By the cooperation of the mounting housing 4 and the mounting housing 5, the driven gear 1 and the bearing 3 can be initially clamped, and then fixed by the locking mechanism, thereby realizing the positioning and clamping of the driven gear 1.

[0024] The interior of the mounting housing 4 is symmetrically provided with two sets of sliding grooves 6. Sliding blocks 7 are slidably connected inside the sliding grooves 6, and the sliding blocks 7 are fixedly connected to the mounting housing 5. By using the sliding grooves 6 inside the mounting housing 4, and the sliding blocks 7 are slidably connected inside the sliding grooves 6 and fixedly connected to the mounting housing 5, the mounting housing 4 and the mounting housing 5 can be assembled by the cooperation of the sliding grooves 6 and the sliding blocks 7.

[0025] An installation block 8 is fixedly installed inside the mounting housing 2 5. Multiple sets of rotating blocks 9 are rotatably installed inside the mounting block 8. A clamping plate 10 is fixedly connected to the top of each rotating block 9. The clamping plate 10 has two sets of symmetrically formed arc-shaped grooves 11 inside. The locking mechanism includes a rotating shaft 12, a screw 13, a threaded slider 14, and fixing blocks 15. Two sets of rotating shafts 12 are symmetrically rotatably installed inside the mounting housing 2 5. The screw 13 is fixedly connected to the surface of the rotating shaft 12. The threaded slider 14 is threadedly connected to the surface of the screw 13 and can slide into the arc-shaped grooves 11. Two sets of fixing blocks 15 are symmetrically fixedly connected to the top of the threaded slider 14. The locking mechanism is achieved by setting... The clamping plate 10 drives the rotating block 9 to rotate along the inside of the mounting block 8, and the clamping plate 10 can contact the surface of the mounting housing 4. At the same time, the mounting block 8 is fixedly connected to the inside of the mounting housing 5. Thus, the clamping plate 10 can rotate along the inside of the mounting block 8 and contact the surface of the mounting housing 4. Then, the screw 13 cooperates with the rotating shaft 12 to drive the screw 13 to slide into the inside of the clamping plate 10. Then, the rotating fixing block 15 drives the threaded slider 14 to rotate, thereby driving the threaded slider 14 to move along the surface of the screw 13 to the inside of the arc-shaped groove 11 and squeeze the clamping plate 10, thereby realizing the fixed installation of the mounting housing 4 and the mounting housing 5.

[0026] In use, the mounting housing 1 4 and mounting housing 2 5 are assembled by the cooperation of the sliding groove 6 and the sliding block 7. Then, the clamping plate 10 is pulled to rotate along the inside of the mounting block 8 and come into contact with the surface of the mounting housing 1 4. Then, the screw 13 is pulled to drive the rotating shaft 12 to rotate along the inside of the mounting housing 2 5 and slide into the inside of the mounting housing 1 4. Then, by rotating the fixing block 15, the threaded slider 14 is driven to slide along the surface of the screw 13 and slide into the inside of the arc-shaped groove 11, and squeeze the clamping plate 10, so as to realize the rapid installation of the mounting housing 1 4 and the mounting housing 2 5 and speed up the installation efficiency of the equipment.

[0027] Both mounting housing 14 and mounting housing 25 are fixedly connected to the inner sides of an arc-shaped plate 16, which can slide into the interior of the driven gear 1. An arc-shaped track is provided on the inner side of the arc-shaped plate 16. Multiple sets of steel balls 17 are rotatably installed inside the driven gear 1, and the steel balls 17 can contact the surface of the arc-shaped track provided on the inner side of the arc-shaped plate 16. Through the cooperation of mounting housing 14 and mounting housing 25, the arc-shaped plate 16 is driven to slide into the interior of the driven gear 1. At the same time, the arc-shaped track is provided inside the arc-shaped plate 16, and the arc-shaped track can contact the surface of the steel balls 17. Thus, through the cooperation of the steel balls 17 and the arc-shaped track, the friction between the driven gear 1 and mounting housing 14 and mounting housing 25 is reduced.

[0028] In use, the arc-shaped track at the bottom of the arc plate 16 contacts the surface of the steel ball 17, thereby reducing friction between the driven gear 1 and the equipment when the driven gear 1 rotates, and increasing the service life of the equipment.

[0029] Working principle: First, the sliding groove 6 cooperates with the sliding block 7 to fit the mounting housing 1 4 and the mounting housing 2 5 onto the surface of the bearing 3. At the same time, the arc plate 16 is driven to slide into the interior of the driven gear 1, and the arc track set inside the arc plate 16 is driven to contact the surface of the steel ball 17. Then, the clamping plate 10 is driven to rotate along the interior of the mounting block 8 and contact the surface of the mounting housing 1 4. Then, the screw 13 is rotated and slid into the interior of the mounting housing 1 4. Then, the fixed block 15 is rotated and the threaded slider 14 is driven to move along the surface of the screw 13 and slide into the interior of the arc groove 11, thereby realizing the positioning and clamping of the driven gear 1.

[0030] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
