Description

Technical Field

[0001] The utility model relates to the technical field of gear shafts, in particular to a novel gear shaft with a dust cover. Background Art

[0002] A gear shaft is a mechanical part, usually used in transmission systems, with a toothed structure such as a gear or rack, which can transmit power and change the speed and torque. It is usually made of solid metal and meshes with other gears or transmission devices through teeth to achieve mechanical transmission functions. Gear shafts are widely used in various mechanical equipment, such as automotive gearboxes, industrial machinery, and machine tools.

[0003] The gear shaft in the prior art generally needs to pass through the housing through a bearing so that the gear shaft can obtain additional support, reduce vibration and deflection, and improve the stability of the entire transmission system. There will be a gap at the penetration of the bearing and the housing, and this gap can easily allow external dust and impurities to enter the interior of the housing, affecting the normal operation of the transmission system. Due to poor sealing, the entry of dust and impurities will lead to problems such as lubricant contamination, increased bearing wear, and reduced transmission efficiency. In addition, the protective shell at the connection is not easy to disassemble and assemble in the prior art. In view of the above problems, technicians in this field have proposed a new gear shaft with a dust cover to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a novel gear shaft with a dust cover, aiming to improve the problem that impurities such as dust may enter through gaps at the penetration point between the bearing and the box body of the gear shaft in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, the sealing assembly includes a limit groove, which is opened inside the cover body, and the inner wall of the limit groove is fixedly connected with multiple springs 2, the bottom ends of the multiple springs 2 are fixedly connected with a limit ring, and the bottom end of the limit ring is fixedly connected with a rubber ring.

[0008] Furthermore, the outside of the protrusion is slidably connected to the inside of the mounting seat, and the inside of the cover body is slidably connected to the outside of the gear shaft body.

[0009] Furthermore, the exterior of the mounting seat abuts against the exterior of the box body, and the interior of the mounting groove is slidably connected to the exterior of the limiting block.

[0010] Furthermore, the interior of the installation slot is slidably connected to the exterior of the clamping block, and the exterior of the clamping block is engaged with the interior of the clamping slot.

[0011] Furthermore, the interior of the mounting seat is slidably connected to the exterior of the pull rod.

[0027] Specifically, through the gear 2 on the gear shaft body 1, power can be transmitted and the speed and torque can be changed. The bearing 3 on the gear shaft body 1 is fixedly connected to the box body 5, thereby improving the stability of the entire transmission system. The bearing 3 and the protrusion 4 limit the mounting seat 6, so that the mounting seat 6 will not shift when it moves. The gear shaft body 1 limits the cover body 7, and the cover body 7 will not shift when it moves. Through the mounting seat 6 and the cover body 7, the connection between the outside of the gear shaft body 1 and the bearing 3 and the box body 5 can be dust-proofed.

[0028] Reference Figure 2-Figure 4 , mounting grooves 8 are provided on the upper and lower sides of the interior of the mounting seat 6, a spring 9 is fixedly connected to the inner wall of the mounting groove 8, the right end of the spring 9 is fixedly connected to a limiting block 10, the interior of the mounting groove 8 is slidably connected to the exterior of the limiting block 10, a clamping block 11 is fixedly connected to the right side of the limiting block 10, the interior of the mounting groove 8 is slidably connected to the exterior of the clamping block 11, a clamping groove 12 is provided on the left side of the interior of the protrusion 4, the exterior of the clamping block 11 is engaged with the interior of the clamping groove 12, a pull rod 13 is fixedly connected to the left side of the limiting block 10, the interior of the mounting seat 6 is slidably connected to the exterior of the pull rod 13, and the exterior of the pull rod 13 is fixedly connected to a pull ring 14.

[0029] Specifically, the mounting groove 8 and the limit block 10 fix the spring 9, so that the spring 9 can stably perform elastic deformation, the mounting groove 8 limits the limit block 10 and the clamping block 11, so that the limit block 10 and the clamping block 11 will not deviate when moving, and the clamping block 11 is engaged with the clamping groove 12, so that the mounting seat 6 can be fixed, and the mounting seat 6 limits the pull rod 13, so that the pull rod 13 will not deviate when moving, and by pulling the pull ring 14 to move to the left, the pull rod 13 is driven to move with it, and then the limit block 10 is driven to move with it, thereby driving the clamping block 11 to move to the left and disengage from the clamping groove 12, so that the mounting seat 6 can be conveniently removed.

[0030] Reference Figure 2 , Figure 5 and Figure 6 A sealing component 15 is provided inside the cover body 7. The sealing component 15 seals and dust-proofs the connection between the gear shaft body 1 and the box body 5. The sealing component 15 includes a limiting groove 1501. The limiting groove 1501 is opened inside the cover body 7. The inner wall of the limiting groove 1501 is fixedly connected with a plurality of springs 1502. The bottom ends of the plurality of springs 1502 are fixedly connected with a limiting ring 1503. The inside of the limiting groove 1501 is slidably connected with the outside of the limiting ring 1503. The bottom end of the limiting ring 1503 is fixedly connected with a rubber ring 1504. The inside of the limiting groove 1501 is slidably connected with the outside of the rubber ring 1504. The inside of the rubber ring 1504 abuts against the outside of the gear shaft body 1.

[0031] Specifically, the second spring 1502 is elastically deformed when installed, so that the second spring 1502 can perform a reset activity inside the limiting groove 1501. The limiting groove 1501 limits the limiting ring 1503 and the rubber ring 1504, so that the limiting ring 1503 and the rubber ring 1504 are stable when moving. The rubber ring 1504 is in contact with the gear shaft body 1, and the spring 1502 is squeezed by the reset activity, so that the rubber ring 1504 is in close contact with the gear shaft body 1, so that dust will not enter the connection, thereby ensuring that the connection will not be affected by dust.

[0032] Working principle: When the mounting seat 6 needs to be installed and fixed, the pull ring 14 is pulled to move to the left, thereby driving the pull rod 13 to move with it, and then driving the limit block 10 to move with it, thereby squeezing the spring 19 to make elastic deformation, and then driving the clamping block 11 to move to the left, so that the mounting seat 6 is moved to the outside of the protrusion 4, and then the spring 19 performs a reset activity, thereby driving the limit block 10 to move to the right, and then driving the clamping block 11 to move with it to the inside of the clamping groove 12, so that the clamping block 11 is engaged with the clamping groove 12, so that the mounting seat 6 can be installed and fixed;

[0033] In addition, when it is necessary to seal the outside of the gear shaft body 1, the spring 2 1502 is installed to allow it to be elastically deformed, so that the cover body 7 is on the outside of the gear shaft body 1, and the spring 2 1502 is reset, thereby driving the limit ring 1503 to move inward, and then driving the rubber ring 1504 to move with it and closely abut against the gear shaft body 1, thereby completing the sealing of the outside of the gear shaft body 1 and protecting the connection between the bearing 3 and the box body 5.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
