Description

Technical Field

[0001] The utility model relates to the technical field of gear shafts, and more specifically, to a high-strength gear shaft with a supporting steel bar. Background Art

[0002] A gear shaft refers to a part that supports a rotating part and rotates with it to transmit motion, torque, and bending moment. Each section of the gear shaft has a different diameter and length, and is generally in the shape of a metal round rod.

[0003] As a mechanical element, the gear shaft is usually used in the gear transmission system. During the transmission process, the contact between the gear shaft and the gear meshing with it will generate pressure and friction. These forces drive the rotation of the gear shaft and the gear. At present, the gear shafts on the market often add supporting steel bars inside the shaft teeth to improve their overall strength. However, it is still inevitable that some shaft teeth will wear and deform after a long period of transmission, which will affect its performance in transmitting power and torque. In order not to affect production efficiency, operators often discard these gear shafts and start to replace them with new ones, which will increase production costs and affect production efficiency, bringing inconvenience to operators' operations, so they need to be improved.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 6 As shown, the utility model provides a high-strength gear shaft with a supporting steel bar, comprising:

[0030] The main shaft 1, the outer surface of the left side of the main shaft 1 is fixedly sleeved with a fixed round block 2, the right side of the fixed round block 2 is provided with a square groove 3, the outer surface of the fixed round block 2 is movably connected with a shaft gear module 4, and the interior of the shaft gear module 4 is fixedly sleeved with a support steel bar 5;

[0031] A rotating mechanism, the rotating mechanism is arranged on the outer surface of the main shaft 1;

[0032] A locking mechanism, which is arranged inside the square groove 3;

[0033] Among them, the locking mechanism includes a moving block 6, the outer surface of the moving block 6 is movably connected to the inside of the square groove 3, a stop block 7 is fixedly installed on the right side of the moving block 6, the left side of the stop block 7 is movably connected to the shaft gear module 4 and the right side of the fixed round block 2 respectively, a first hinge block 8 is fixedly installed on the right side of the stop block 7, a moving rod 9 is hinged inside the first hinge block 8, the other end of the moving rod 9 is hinged to a second hinge block 10, and the other end of the second hinge block 10 is fixedly installed with a moving ring 11.

[0034] When the moving ring 11 moves to the right, the four second hinged blocks 10 will drive the four moving rods 9 to move at the same time, and then the other ends of the four moving rods 9 will respectively drive the four first hinged blocks 8 to move. At this time, the four first hinged blocks 8 will drive the four moving blocks 6 to move through the four stop blocks 7. Due to the limiting effect inside the four square grooves 3, the four moving blocks 6 and the four stop blocks 7 will move in phase at the same time.

[0035] The rotating mechanism includes:

[0036] A threaded block 12, the interior of the threaded block 12 is fixedly sleeved with the outer surface of the main shaft 1;

[0037] The rotating ring 13 has an interior that is threadedly sleeved with an outer surface of the threaded block 12 , and an outer surface of the rotating ring 13 that is movably sleeved with an interior of the moving ring 11 .

[0038] When the rotating ring 13 rotates, since the outer surface of the threaded block 12 is provided with threads, the rotating ring 13 will rotate and move rightward at the same time, and the moving ring 11 will move rightward driven by the rotating ring 13 .

[0039] The left side of the fixed circular block 2 is fixedly mounted with an annular block 14 , and the right side of the annular block 14 is movably connected to the left side of the shaft-tooth module 4 .

[0040] Due to the design of the annular block 14 , the shaft-tooth module 4 is blocked.

[0041] A fixing block 15 is fixedly installed on the right side of the main shaft 1 , and clamping blocks 16 are movably connected to the outer surfaces of the front and rear sides of the fixing block 15 .

[0042] Due to the design of the two clamping blocks 16 , the fixing block 15 can be well clamped.

[0043] Among them, the right side of the clamping block 16 is movably connected to a circular block 17, and the front and rear ends of the left side of the circular block 17 are provided with limiting grooves 18. The inside of the limiting groove 18 is movably connected to a movable block 19, and the left side of the movable block 19 is fixedly connected to the right side of the clamping block 16.

[0044] Due to the design of the two limiting grooves 18, the two movable blocks 19 are limited so that they can only move forward and backward.

[0045] The front and rear ends of the circular block 17 are both fixedly mounted with square blocks 20 , and the interior of the square block 20 is movably sleeved with a rotating block 21 .

[0046] The two rotating blocks 21 can rotate inside the two square blocks 20 respectively.

[0047] Among them, a threaded rod 22 is fixedly installed on the other end of the rotating block 21, and the other end of the threaded rod 22 passes through the outer surface of the circular block 17 and extends to the inside of the limiting groove 18. The other end of the threaded rod 22 is movably connected to the inside of the limiting groove 18, and the outer surface of the threaded rod 22 is engaged with the internal thread of the movable block 19.

[0048] When the two rotating blocks 21 drive the two threaded rods 22 to rotate respectively, the two movable blocks 19 will move away from each other under the drive of the two threaded rods 22, thereby causing the two clamping blocks 16 to move away from each other.

[0049] The working principle and use process of this utility model:

[0050] First, the operator rotates the rotating ring 13. Since the rotating ring 13 is threadedly sleeved on the outer surface of the threaded block 12, the rotating ring 13 will move to the right along the outer surface of the threaded block 12 during the rotation. At this time, the moving ring 11 will move to the right driven by the rotating ring 13. At the same time, the four second hinge blocks 10 will move to the right driven by the moving ring 11. Then the four moving rods 9 will move driven by the four second hinge blocks 10. At this time, the other ends of the four moving rods 9 will drive the four first hinge blocks 8 to move. Subsequently, the four first hinge blocks 8 will drive the four moving blocks 6 to move through the four stop blocks 7. Due to the design inside the four square grooves 3, the movement of the four moving blocks 6 will be limited. At this time, the four moving blocks 6 and the four stop blocks 7 will move inward at the same time under the limitation inside the four square grooves 3, thereby realizing the function of convenient replacement of the damaged shaft gear module 4.

[0051] Then the operator rotates the two rotating blocks 21 at the same time, and the two rotating blocks 21 will respectively drive the two threaded rods 22 to rotate. Since the two movable blocks 19 are respectively threadedly sleeved with the outer surfaces of the two threaded rods 22, the two threaded rods 22 will respectively drive the two movable blocks 19 to move during rotation. Due to the internal design of the two limit grooves 18, the movement of the two movable blocks 19 will be limited. At this time, the two movable blocks 19 will move away from each other, and then the two clamping blocks 16 will move away from each other under the drive of the two movable blocks 19. At this time, the two clamping blocks 16 will release the clamping and fixing effect on the fixed block 15 during the away-to-away movement, thereby realizing the function of facilitating the replacement of the entire spindle 1.
