Description

Technical Field

[0001] This utility model relates to the field of gearbox repair, specifically a spindle mounting bracket for gearbox repair. Background Technology

[0002] The gearbox spindle is one of the core components of the gearbox, undertaking important functions such as transmitting power, supporting gears and transmission devices.

[0003] When installing or inspecting the spindle, the gearbox needs to be disassembled, and then the spindle is placed on the support before it can be installed or inspected. Because the support used now consists of a base and a support rod, the spindle may shift after it is placed because the size of the support rod is different from the center clearance of the spindle. This can cause the edge of the spindle to rub against the base, and some larger spindles may come into contact with the ground after shifting position. This can cause wear on the outside of the spindle, resulting in damage to the spindle and rendering it unusable. Utility Model Content

[0004] To overcome the shortcomings of existing technology and solve the problems that the position of the main shaft may shift due to the difference between the size of the support rod and the center clearance size of the main shaft, resulting in friction between the edge of the main shaft and the base, and that some larger main shafts may come into contact with the ground after the position changes, which will cause wear on the outer side of the main shaft, resulting in damage to the main shaft and subsequent unusability, this utility model proposes a main shaft placement support for gearbox repair.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The main shaft placement support for gearbox repair of this utility model includes a base, a support assembly is provided on the outside of the base, the support assembly includes a rotating disk rotatably connected to the inside of the base, four first sliding grooves are opened inside the rotating disk, a first support rod is slidably connected inside the first sliding groove, a sliding disk is fixedly connected to the bottom of the first support rod, and eight balls are rotatably connected inside the rotating disk, the eight balls are divided into two groups.

[0006] Preferably, the base is provided with an auxiliary component, which includes four second sliding grooves opened inside the base. The interior of the second sliding grooves is slidably connected to the interior of the sliding disk. The base is provided with a ball groove, which is slidably connected to the outside of the ball.

[0007] Preferably, a limiting component is provided on the outer side of the rotating disk. The limiting component includes a sleeve fixedly connected to the inside of the rotating disk. A slot is formed inside the sleeve, and a limiting groove is formed inside the sleeve.

[0008] Preferably, the sleeve is provided with a pressing component, the pressing component includes a slide rod slidably connected inside the sleeve, the slide rod passes through the sleeve, and a knob is fixedly connected to the top of the slide rod, the knob having a screw hole inside.

[0009] Preferably, the pressing assembly further includes a second support rod fixedly connected to the bottom of the knob, the outer side of the second support rod being slidably connected to the inside of the slot, a locking block being fixedly connected to the outer side of the slide rod, the outer side of the locking block being slidably connected to the inside of the limiting groove, and a spring being fixedly connected between the bottom of the knob and the top of the locking block.

[0010] Preferably, the bottom of the sleeve is rotatably connected to the inside of the base, and the sleeve passes through the base and is rotatably connected.

[0011] Preferably, the second support rod has the same dimensions as the slide rod, and the bottom of the second support rod abuts against the bottom of the inner cavity of the sleeve.

[0012] The advantages of this utility model are:

[0013] 1. This utility model involves placing the spindle on top of the base, then rotating the knob to rotate the rotating disk, which in turn causes the first support rod to slide inside the first groove. This causes the four first support rods to move closer or further apart, so that the outer side of the first support rod abuts against the inside of the central mounting hole of the spindle. This restricts the position of the spindle, thereby reducing the possibility of damage to the spindle and its outer side, allowing the spindle to continue to be used and reducing economic losses.

[0014] 2. This utility model uses a pull knob to lift the locking block, thereby compressing the spring. Then, the cross-shaped pressing block is threaded into the screw hole. After releasing the force of pulling the knob, the bottom of the pressing block is pressed against the top of the spindle. This further restricts the position of the spindle, thereby ensuring the safety of the spindle and further reducing the possibility of damage to the outside of the spindle.

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-3 As shown, a spindle support for gearbox maintenance includes a base 1. A support assembly is provided on the outside of the base 1. The support assembly includes a rotating disk 2 rotatably connected to the inside of the base 1. The rotating disk 2 has four first sliding grooves 5. A first support rod 4 is slidably connected inside the first sliding grooves 5. A sliding disk 3 is fixedly connected to the bottom of the first support rod 4. Eight ball bearings 6 are rotatably connected inside the rotating disk 2. The eight ball bearings 6 are divided into two groups.

[0025] During operation, the rotation of the rotating disk 2 causes the first support rod 4 to slide inside the first slide groove 5, thereby causing the four first support rods 4 to move closer or further apart. This allows the outer side of the first support rod 4 to abut against the inside of the central mounting hole of the spindle, thus restricting the position of the spindle and reducing the possibility of damage to the spindle, as well as the possibility of damage to the outer side of the spindle. This allows the spindle to continue to be used, thereby reducing economic losses.

[0026] The base 1 is equipped with an auxiliary component, which includes four second sliding grooves 8 inside the base 1. The second sliding grooves 8 are slidably connected to the sliding disk 3. The base 1 is provided with a ball groove 7 inside, which is slidably connected to the outside of the ball 6.

[0027] During operation, the position of the sliding disk 3 can be restricted by the second slide groove 8, and then the position of the ball 6 can be restricted by the ball groove 7, thereby ensuring that the device can work smoothly.

[0028] Among them, a limiting component is provided on the outside of the rotating disk 2. The limiting component includes a sleeve 9 fixedly connected to the inside of the rotating disk 2. A slot 10 is opened inside the sleeve 9, and a limiting groove 11 is opened inside the sleeve 9.

[0029] During operation, rotating the sleeve 9 can drive the rotating disk 2 to rotate.

[0030] The bottom of the sleeve 9 is rotatably connected to the inside of the base 1, and the sleeve 9 passes through the base 1 and is rotatably connected.

[0031] During operation, the sleeve 9 is rotated and connected to the base 1 to ensure the stability of the sleeve 9.

[0032] Example 2

[0033] Please see Figure 4-5 As shown in the first embodiment, as another implementation of this utility model, the sleeve 9 is provided with a pressing component. The pressing component includes a slide rod 12 that is slidably connected inside the sleeve 9. The slide rod 12 passes through the sleeve 9, and a knob 13 is fixedly connected to the top of the slide rod 12. A screw hole is opened inside the knob 13.

[0034] The pressing assembly also includes a second support rod 14 fixedly connected to the bottom of the knob 13. The outer side of the second support rod 14 is slidably connected to the inside of the slot 10. A locking block 16 is fixedly connected to the outer side of the slide rod 12. The outer side of the locking block 16 is slidably connected to the inside of the limiting groove 11. A spring 15 is fixedly connected between the bottom of the knob 13 and the top of the locking block 16.

[0035] During operation, after the spindle is placed, the knob 13 is pulled to raise the locking block 16, thereby compressing the spring 15. Then, the cross-shaped pressing block is threaded into the screw hole. Next, the force of pulling the knob 13 is released, so that the bottom of the pressing block presses against the top of the spindle. This further restricts the position of the spindle, thereby ensuring the safety of the spindle and further reducing the possibility of damage to the outside of the spindle.

[0036] The second support rod 14 has the same dimensions as the slide rod 12, and the bottom of the second support rod 14 abuts against the bottom of the inner cavity of the sleeve 9.

[0037] During operation, by setting the second support rod 14 and the slide rod 12 to the same size, it is ensured that the second support rod 14 will not fall off when the slide rod 12 is pulled to its maximum length.

[0038] The working principle is as follows: First, the spindle is placed on top of the base 1. Then, the knob 13 is turned, which drives the rotating disk 2 to rotate. This causes the first support rod 4 to slide inside the first slide groove 5, thereby making the four first support rods 4 move closer or further away from each other. This allows the outer side of the first support rod 4 to abut against the inside of the central mounting hole of the spindle. This restricts the position of the spindle, thereby reducing the possibility of damage to the spindle and the outer side of the spindle. This allows the spindle to continue to be used, thereby reducing economic losses.

[0039] When the spindle position is restricted, the lever 13 can be pulled to raise the locking block 16, thereby compressing the spring 15. Then, the cross-shaped pressing block is threaded into the screw hole. Next, the force of pulling the lever 13 is released, so that the bottom of the pressing block presses against the top of the spindle. This can further restrict the position of the spindle, thereby ensuring the safety of the spindle and further reducing the possibility of damage to the outside of the spindle.
