Description

Technical Field

[0001] The utility model relates to the technical field of supporting gear shafts, and more specifically, to a wear-resistant supporting gear shaft. Background Art

[0002] As a mechanical element, the gear shaft is usually used in a gear transmission system as a part of the gear teeth to achieve the transmission of power and torque.

[0003] The gear shaft usually has the shape and size of a gear and is embedded on the outer edge of the wheel. It meshes with another gear and transmits the torque of the input shaft to the output shaft through the meshing action of the teeth. During the transmission process, the contact between the gear shaft and the gear meshing with it will generate pressure and friction, which will cause wear of the gear shaft. In order to extend the service life of the gear shaft, operators often spray or apply lubricating oil on the gear shaft from time to time, thereby reducing the friction between the gear shaft and the gear and increasing the wear resistance of the gear shaft. However, this method is time-consuming and labor-intensive, and there is a certain risk in oiling the high-speed rotating gear shaft, which brings inconvenience to the operator's operation, so it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a wear-resistant supporting gear shaft, which has the advantage of automatically lubricating the gear shaft.

DETAILED DESCRIPTION

[0025] 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.

[0026] like Figures 1 to 6 As shown, the utility model provides a wear-resistant supporting gear shaft, comprising:

[0027] A main shaft 1, a limiting groove 2 is provided at the top of the left side of the outer surface of the main shaft 1, a square groove 3 is provided on the left side of the outer surface of the main shaft 1, a first capillary 7 is provided on the outer surface of the main shaft 1, an annular cavity 4 is provided inside the left side of the main shaft 1, and the inside of the annular cavity 4 is connected with the inside of the limiting groove 2 and the square groove 3;

[0028] An oiling mechanism, the oiling mechanism is arranged on the outer surface of the main shaft 1;

[0029] Among them, the oiling mechanism includes a circular ring 6, the interior of the circular ring 6 is fixedly sleeved with the outer surface of the main shaft 1, and a gear 8 is movably connected to the left side of the circular ring 6. The interior of the gear 8 is movably sleeved with the outer surface of the main shaft 1, and a second capillary 9 is opened inside the gear 8. The interior of the second capillary 9 is connected to the interior of the main shaft 1 through the first capillary 7.

[0030] When the main shaft 1 rotates, the lubricating oil inside the main shaft 1 will move to the outer surface of the gear 8 through the first capillary tube 7 and the second capillary tube 9 under the action of centrifugal force, thereby lubricating the outer surface of the gear 8.

[0031] A positioning block 10 is fixedly mounted on the outer surface of the main shaft 1 , and the outer surface of the positioning block 10 is movably connected to the inside of the gear 8 .

[0032] Due to the positioning function of the four positioning blocks 10 , the interior of the second capillary tube 9 can be connected with the interior of the first capillary tube 7 .

[0033] An oil inlet 5 is fixedly installed on the left side of the main shaft 1 , and a fixing block 11 is fixedly installed on the right side of the outer surface of the main shaft 1 .

[0034] Due to the design of the oil inlet 5 , the operator can easily oil the inside of the main shaft 1 .

[0035] Among them, a moving block 12 is movably installed inside the limiting groove 2, and the bottom end of the moving block 12 extends to the inside of the annular cavity 4 through the limiting groove 2. An annular block 13 is fixedly installed at the bottom end of the moving block 12, and the outer surface of the annular block 13 is movably sleeved with the inside of the annular cavity 4.

[0036] Due to the limiting effect inside the limiting groove 2, the movement of the moving block 12 will be limited. When the moving block 12 moves to the right, the moving block 12 will drive the annular block 13 to move to the right along the inside of the annular cavity 4.

[0037] A moving rod 14 is fixedly mounted on the right side of the annular block 13 , and an extrusion block 15 is fixedly mounted on the other end of the moving rod 14 .

[0038] When the annular block 13 moves to the right, the annular block 13 will drive the four extrusion blocks 15 to move to the right through the four movement rods 14 .

[0039] The outer surface of the extrusion block 15 is movably connected to the movable block 16 , the right side of the movable block 16 is movably connected to the inside of the annular cavity 4 , and the outer surface of the movable block 16 is movably connected to the inside of the square groove 3 .

[0040] Since the interior of the four movable blocks 16 is designed to be inclined, when the four extrusion blocks 15 move to the right, the interior of the four movable blocks 16 will be squeezed, thereby causing the four movable blocks 16 to move. Due to the limiting effect inside the four square grooves 3, the four movable blocks 16 will move to the outside of the main shaft 1 at the same time, thereby locking the gear 8.

[0041] An arc block 17 is fixedly mounted on the top of the left outer surface of the main shaft 1 , and a round rod 18 is movably sleeved inside the arc block 17 .

[0042] When the round rod 18 rotates ninety degrees, it will block the movement of the moving block 12 .

[0043] The working principle and use process of this utility model:

[0044] First, the operator pushes the gear 8 to move along the outer surface of the main shaft 1, and stops when the right side of the gear 8 contacts the left side of the ring 6. Due to the design of the four positioning blocks 10, the interior of the second capillary 9 will be connected to the interior of the main shaft 1 through the first capillary 7. At this time, the operator pushes the moving block 12 to make the moving block 12 move. Due to the design of the interior of the limiting groove 2, the movement of the moving block 12 will be limited. At this time, the moving block 12 will move to the right along the interior of the limiting groove 2. When the right side of the moving block 12 contacts the left side of the arc block 17, the outer surface of the round rod 18 will be movably connected to the interior of the moving block 12, and the left side of the round rod 18 will be located at the moving block 12. On the outside of the left side, at the same time, the annular block 13 will move to the right along the inside of the annular cavity 4 driven by the moving block 12, and then the annular block 13 will simultaneously drive the four moving rods 14 to move to the right. At this time, the four moving rods 14 will simultaneously drive the four extrusion blocks 15 to move to the right. Due to the internal design of the movable block 16, the four extrusion blocks 15 will respectively squeeze the inside of the four movable blocks 16 during the rightward movement, so that the four movable blocks 16 respectively move along the inside of the four square grooves 3 to the outside of the main shaft 1 at the same time, thereby realizing the function of locking the gear 8. Then the operator rotates the round rod 18 ninety degrees, and the round rod 18 will block the movement of the moving block 12.

[0045] Then the operator injects lubricating oil into the interior of the main shaft 1 through the oil inlet 5. When the main shaft 1 rotates as a whole, the lubricating oil inside the main shaft 1 will move to the interior of the second capillary 9 through the first capillary 7 under the action of centrifugal force. Then, the lubricating oil inside the second capillary 9 will move to the outer surface of the gear 8 under the action of centrifugal force, thereby realizing automatic lubrication of the outer surface of the gear 8 and improving the wear resistance of the gear 8.
