Description

Technical Field

[0001] The utility model relates to the technical field of gear shafts, and more specifically to a high-strength walking beam input shaft. Background Art

[0002] The high-strength walking beam input shaft is an important component of the mechanical transmission system, which is mainly responsible for transmitting power to the output shaft. Since it needs to withstand large torque and load, the input shaft is usually made of high-strength materials to ensure its stability and reliability during operation. The accuracy of the input shaft directly affects the working efficiency and accuracy of the entire transmission system, so there are high requirements for its processing accuracy and assembly accuracy. Since it works in a high-speed and heavy-load environment for a long time, the input shaft needs to have good wear resistance to extend its service life. The design of the input shaft needs to take into account its coordination with the output shaft, transmission gears and other components to achieve efficient power transmission. The manufacturing of the high-strength walking beam input shaft requires multiple process links such as forging, heat treatment, and finishing, and the manufacturing difficulty is relatively high. In order to ensure the normal operation of the input shaft and extend its service life, it needs to be inspected and maintained regularly, such as lubrication and replacement of worn parts.

[0003] Deficiencies of existing technology: Most of the existing gear shafts have teeth machined on the side of the gears to connect the gears to each other. After working for a long time, the teeth of the main shaft and the teeth of the secondary shaft rub against each other, which will cause the teeth on the two gears to be partially worn away, resulting in slippage and other faults during transmission. On the other hand, the main shaft of the existing equipment and the gears that mesh with each other are always in high-speed operation. The friction and wear will seriously affect the service life of the gears. However, to maintain the gear equipment, it is often necessary to stop the equipment and then disassemble it to apply lubricating oil for maintenance, which greatly shortens and reduces work efficiency and time. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a high-strength walking beam input shaft to solve the problems existing in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-strength walking beam input shaft, comprising a gear main shaft, the inner cavity of the gear main shaft is provided with a reinforcing thread, the inner cavity of the gear main shaft is provided with a retained liquid cavity, the inner wall of the side of the reinforcing thread is provided with an internal thread, the side of the gear main shaft is provided with an embedded groove, and the inner wall side wall of the internal thread is threadedly connected with a sealing nut.

[0006] Furthermore, a reinforcement thread is provided on the outer edge of the side surface of the gear main shaft, and a reinforcement bolt is threadedly connected to the outer edge of the side surface of the reinforcement thread.

[0011] Technical effects and advantages of the utility model:

[0012] The utility model is provided with a gasket, which is conducive to the gasket being placed between two surfaces to block the passage of fluid, gas or particles, prevent leakage and pollution. In the manufacture of machinery and equipment, the gasket is mainly used to prevent the leakage of liquid or gaseous media and protect the system from the influence of the external environment. The gasket can reduce the friction and wear between the two contact surfaces, protect the parts from damage, and extend the service life of the equipment. In some cases, the gasket can be used to adjust the gap or levelness between parts to ensure the normal operation of the equipment. The gasket has a buffering property, can absorb vibration and impact, and reduce the influence of noise and vibration on the equipment.

[0013] The utility model is provided with a qualified oil outlet groove for the retained liquid cavity, and the gear maintenance and oiling are beneficial to the gear oil, which can reduce the wear of the gears and other moving parts and extend the life of the gears. It forms a lubricating film on the surface of the gear, reduces the direct contact between the tooth surfaces, thereby reducing friction and wear. The gear oil continuously takes away the heat generated by the gear transmission during the circulation lubrication process, and dissipates it through the air and the transmission mechanism housing to ensure the normal working temperature of the transmission parts. The gear oil can prevent the corrosion and rust of the gears and bearings, protect the geometric characteristics and lubrication state of the gears, and extend their service life. The use of gear oil can reduce the friction and transmission loss of the gear transmission and improve the mechanical efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Among them, a reinforcing thread 106 is opened on the outer edge of the side of the gear main shaft 1, and a reinforcing bolt 102 is threadedly connected to the outer edge of the side of the reinforcing thread 106 to fix and tighten the side gear 201 and the inner main shaft gear 3.

[0023] Among them, an oil outlet groove 107 is opened on the inner wall side wall of the retained liquid chamber 101. The engine oil stored in the retained liquid chamber 101 is beneficial to the maintenance of the gears. Oiling the gear oil can reduce the wear of the gears and other moving parts and extend the life of the gears. It forms a lubricating film on the surface of the gears to reduce the direct contact between the tooth surfaces, thereby reducing friction and wear. The gear oil continuously takes away the heat generated by the gear transmission during the circulation lubrication process and dissipates it through the air and the transmission mechanism casing to ensure the normal operating temperature of the transmission parts. The gear oil can prevent corrosion and rust of the gears and bearings, protect the geometric characteristics and lubrication state of the gears, and extend their service life. The use of gear oil can reduce the friction and transmission loss of the gear transmission and improve mechanical efficiency. The side of the gear main shaft 1 is fixedly connected with the inner main shaft gear 3.

[0024] Among them, the side of the reinforcing bolt 102 is movably connected with an iron washer 108. The purpose of adding the washer is to reduce the friction and wear between the two contact surfaces, protect the parts from damage, and extend the service life of the equipment. In some cases, the washer can be used to adjust the gap or level between the components to ensure the normal operation of the equipment. The washer has a buffering property, which can absorb vibration and impact and reduce the impact of noise and vibration on the equipment.

[0025] An oil outlet 301 is formed on the side surface of the inner main shaft gear 3 , and an engagement groove 302 is formed on the side surface of the inner main shaft gear 3 .

[0026] Among them, the side of the gear main shaft 1 is movably connected with the side gear 2, and the side of the side gear 2 is provided with an engaging tooth block 202. The inner ring side wall of the side gear 2 is fixedly connected with an elliptical gear support rod 201, and the engaging tooth block 202 on the side gear 2 is inserted into the engaging groove 302 on the gear main shaft 1 with the side facing inward.

[0027] Working principle of the utility model: before use, install it first, align and insert the meshing tooth block 202 on the side gear 2 with the meshing groove 302 on the gear main shaft 1 facing inward, then after the iron washer 108 is sleeved on the gear main shaft 1 and the side gear 2, finally fix the reinforcing bolt 102 through the reinforcing thread 106 threaded connection. The role of adding gaskets is to reduce the friction and wear between the two contact surfaces, protect the parts from damage, and extend the service life of the equipment. In some cases, gaskets can be used to adjust the gap or levelness between components to ensure the normal operation of the equipment. The gasket has a buffering property, can absorb vibration and impact, and reduce the impact of noise and vibration on the equipment. The oil outlet groove 107, the oil outlet 301, the reinforcing thread 106 and the retained liquid cavity 101 opened inside the gear main shaft 1 are connected to each other. When the equipment is not in use In this case, if you want to apply lubricating oil or engine oil to the equipment for maintenance, you can use auxiliary working tools to inject these liquids into the embedded groove 104 opened on the gear main shaft 1, and temporarily store the liquid in the retention liquid chamber 101. Then, the equipped 103 is connected to the side of 1 through the 105 thread, so that the liquid will not flow out from one end at will. Then, when the equipment is turned on for work, when the entire gear main shaft 1 starts to work, it will start to rotate. The force generated during the rotation will rotate the liquid stored in the retention liquid chamber 101 out, thereby lubricating the inner main shaft gear 3. The inner main shaft gear 3 is in frictional contact with the gear connection, so that the inner main shaft gear 3 and the contacting gears will be evenly sticky with lubricating oil, etc., and oiling the gears is beneficial to extending their service life. The use of gear oil can reduce the friction and transmission loss of the gear transmission and improve mechanical efficiency.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
