Description

Technical Field

[0001] The utility model relates to the field of mechanical gearboxes, specifically to the gearbox of corn harvesting machinery. Background Technique

[0002] With the continuous progress of modern agricultural technology and the in-depth development of agricultural mechanization, corn harvesting machinery has occupied a crucial position in agricultural production. As a key component of corn harvesting machinery, the performance of the corn header gearbox directly determines the efficiency and quality of corn harvesting operations. The gearbox is not only responsible for transmitting the power generated by the engine to the working components of the header, but also for performing necessary speed conversion and torque distribution during the power transmission process to ensure that the header can efficiently and stably complete operations such as reaping, pulling the stalks, and ear picking.

[0003] However, the corn header gearboxes widely used in the current market generally face some technical challenges and limitations. First of all, the weight problem of the gearbox is particularly prominent. Due to the traditional design often using heavy materials for manufacturing, the overall weight of the gearbox is relatively large, which not only increases the load of the mechanical system but also affects the mobility and operation stability of the whole machine. Secondly, the imperfect lubrication system is also an urgent problem to be solved. Insufficient lubrication or poor sealing often leads to increased wear of the internal components of the gearbox and even causes failures, thus reducing the reliability and service life of the gearbox.

[0040] In the preferred scheme of the above corn harvesting machinery gearbox:

[0041] Overall structure and working principle

[0042] The corn harvesting machinery gearbox realizes the transmission of power from the input shaft 4 to the output shaft through its internally precision-designed gear system, and adjusts the rotational speed and torque as required. The gearbox is made of aluminum material, which has the characteristics of light weight and high strength, can effectively reduce the weight of the whole machine, and improve the mobility and stability of the mechanical system.

[0043] An end cover 7 is installed at one end of the gearbox, and a positioning shaft 8 is installed at the other end.

This design enables the drive shaft 3 to rotate stably in the gearbox and effectively transmit power.

[0044] Working principle of the gear transmission system

[0045] Cylindrical gear transmission: The driving gear 1, driving gear 2, input gear 1, output gear 1 and output gear 3 are designed with cylindrical gears. When the input shaft 4 rotates, power is transmitted to the driving gear 2 through the meshing of the input gear 1 and the input gear 2. The driving gear 2 further transmits the power to the driving gear 1, and the driving gear 1 then transmits the power to the driving gear 3 and the driving gear 4. Finally, the driving gear 3 and the driving gear 4 transmit the power to the output shaft 1 and the output shaft 2 through the output gear 2 and the output gear 4 respectively. The parallel axis design of the cylindrical gears makes the power transmission stable and reliable.

[0046] Bevel gear transmission: The driving gear 3, output gear 2 and output gear 4 are designed with single-sided bevel gears, while the driving gear 4 is a double-sided bevel gear. This design enables the gearbox to achieve power transmission between non-parallel axes, increasing the flexibility and adaptability of the gearbox. The meshing shape of the bevel gears is conical, allowing the gears to withstand certain radial and axial loads while transmitting power.

[0047] Dust-proof and lubrication system

[0048] Dust-proof cover 20 design: Dust-proof covers 20 are installed at the output ports on the top and back of the housing 1 to prevent dust and debris from entering the interior of the gearbox and ensure the normal operation of the gearbox.

[0049] Lubrication system: The interior of the gearbox is equipped with a lubrication system. Through the configuration of oil nozzles and oil plugs 9, it is convenient for users to add lubricating oil. The lubricating oil can reduce the wear of components such as gears and bearings, and improve the service life and reliability of the gearbox. The oil nozzles and oil plugs 9 provided at the end cover 7 and the input part 2 enable users to easily add and replace the lubricating oil.

[0067] Output gear: It is installed on the output shaft and meshes with the transmission gear to achieve power transmission.

[0068] Working principle:

[0069] When the engine or the power output shaft rotates, power is transmitted to the second transmission gear 13 through the meshing of the first input gear 11 and the second input gear 12.

[0070] The second transmission gear 13 then transmits the power to the first transmission gear 10, and further transmits the power to the second output gear 16 and the fourth output gear 18 respectively through the third transmission gear 14 and the fourth transmission gear 19.
