Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a power input gearbox for a square baler. Background Technology

[0002] In the field of agricultural mechanization, square balers are an important type of agricultural machinery and equipment, widely used in baling operations for crops such as straw and forage. They are of great significance for improving agricultural production efficiency and promoting the comprehensive utilization of straw.

[0003] The power input gearbox of a square baler is one of its key components, responsible for transmitting external power to the various working mechanisms of the baler to ensure the normal operation of the baling process. Currently, existing power input gearboxes for square balers have certain limitations in terms of structural design and functional implementation.

[0004] On the one hand, traditional power input gearboxes typically use a fixed connection between the housing and mounting components, which places strict requirements on the installation space and angle when installed on customer machines. If the installation environment or layout of the customer machine changes, the existing gearbox may not be suitable, leading to installation difficulties, or even requiring redesign or replacement of the gearbox. This not only increases equipment costs but also prolongs the equipment commissioning and installation cycle, affecting the progress of agricultural production.

[0005] On the other hand, due to differences in the transmission systems and operating requirements of different customer machines, existing power input gearboxes are insufficient in terms of adaptability to power transmission direction and angle. When the transmission direction of the customer machine is inconsistent with the default power transmission direction of the gearbox, it is often necessary to convert it through additional transmission components. This not only increases the complexity of the transmission system and the risk of failure, but may also lead to a reduction in power transmission efficiency, affecting the working performance and operation quality of the baler. Utility Model Content

[0006] To address the shortcomings of existing square balers, such as inconvenient installation and poor adaptability, the purpose of this utility model is to provide a power input gearbox for square balers, which improves the gearbox's versatility and ease of installation, ensuring that the equipment can better adapt to the installation environment and working requirements of different customers, while guaranteeing stable operation and efficient power transmission.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a power input gearbox for a square baler, comprising:

[0008] A housing, wherein a first side and a second side are arranged adjacent to each other;

[0009] The first lid protrudes from the first side of the box body;

[0010] The second lid protrudes from the second side of the box body;

[0011] An input shaft is rotatably connected to the housing, with one end extending from the first housing cover to the outside of the housing for inputting power; an output shaft is rotatably connected to the housing, with one end extending from the second housing cover to the outside of the housing for outputting power; the input shaft and output shaft are drive-connected and arranged perpendicularly; a connecting plate is provided between the second housing cover and the housing, and a tapered roller bearing is provided between the second housing cover and the connecting plate to allow relative rotation between the housing and the second housing cover.

[0012] In this technical solution, the gearbox, with its connecting disc and second cover connected by tapered roller bearings and the connecting disc and gearbox body bolted together, can still rotate relative to each other after being fixedly installed on the customer's machine. This allows for flexible adaptation to various complex installation environments, easily handling situations with limited space or specific installation angle requirements, greatly improving the equipment's versatility and installation success rate. Installation is simplified by rotating the gearbox body and second cover; adjusting to the optimal matching angle through relative rotation effectively simplifies the installation process, shortens the equipment debugging and installation cycle, and improves work efficiency. The input and output shafts are arranged perpendicularly and connected by a transmission mechanism, resulting in a rational structural layout that effectively transmits input power to the output shaft in a predetermined direction and proportion. Simultaneously, the tapered roller bearings not only ensure relative rotation between the gearbox body and the connecting disc but also provide stable support for power transmission, reducing energy loss due to friction and vibration between components. This ensures high efficiency and stability of power transmission, meeting the high power requirements of square balers during baling operations. The relative rotation between the housing and the connecting plate allows for flexible adjustment of the power output direction, eliminating the need for additional transmission components and adapting to diverse transmission requirements. This simplifies the overall transmission system structure, reduces the probability of failure, and improves the reliability and lifespan of the transmission system.

[0013] This invention further comprises: the gearbox includes an input bevel gear and an output bevel gear. The input bevel gear is connected to an input shaft inside the gearbox, and the output bevel gear is connected to an output shaft inside the gearbox and meshes with the input bevel gear. The meshing design of the input and output bevel gears efficiently converts the rotational power of the input shaft into the required rotational power of the output shaft. The unique tooth profile of the bevel gears allows for a smooth transition during power transmission, reducing energy loss during conversion and improving power transmission. Because the input and output shafts are arranged vertically, the bevel gear meshing method is well-suited to this vertical transmission scenario, accurately converting the horizontal rotational motion of the input shaft into the vertical rotational motion of the output shaft, achieving efficient power transmission in different directions. This makes the gearbox more flexible in its structural layout and better adaptable to the space constraints and transmission requirements inside the square baler.

[0014] This invention is further configured such that a third cover is provided on the housing, which is connected to the first cover and used to fix the oil seal. The oil seal is used to prevent lubricating oil leakage from the housing and to prevent external dust, impurities, etc. from entering the housing. The third cover, connected to the first cover, provides a more stable installation position for the oil seal and enhances its sealing effect on the input shaft. During the operation of the square baler, the input shaft rotates continuously. The oil seal fixed by the third cover can effectively prevent lubricating oil from leaking from the connection between the input shaft and the housing, avoiding insufficient lubrication of gears and other components due to lubricating oil loss. It also prevents external contaminants from entering the housing, reducing wear and corrosion on internal gears and bearings, and extending the service life of the equipment. The fixing effect of the third cover on the oil seal ensures that a relatively closed space is formed inside the housing, reducing the possibility of external dust, moisture, and other impurities entering. This helps maintain the cleanliness of the lubricating oil inside the housing, reduces the risk of lubricating oil deterioration, thereby improving the lubrication effect and further ensuring the normal operation of all components inside the gearbox.

[0015] This invention is further configured such that: a first inner skeleton oil seal is provided between the input shaft and the first housing cover, and a second inner skeleton oil seal is provided between the output shaft and the second housing cover. The inner skeleton oil seal has a unique structure and excellent sealing performance. The placement of the first and second inner skeleton oil seals between the input shaft and the first housing cover, and between the output shaft and the second housing cover, effectively prevents lubricating oil inside the housing from leaking from the connection between the shaft and the housing cover. During the operation of the square baler, the shaft rotates continuously at high speed. The inner skeleton oil seal, with its elastic sealing lip tightly fitting the shaft, forms a reliable sealing barrier, ensuring that the lubricating oil is always retained inside the housing, maintaining good lubrication of gears and other components. In addition to preventing lubricating oil leakage, the inner skeleton oil seal can also effectively prevent external dust, moisture, impurities, and other contaminants from entering the housing. Once these contaminants enter the housing, they may adhere to the surfaces of gears, bearings, and other components, increasing frictional resistance, accelerating component wear, and even causing component jamming or other malfunctions. The presence of the inner skeleton oil seal provides a relatively clean environment inside the housing, ensuring the normal operation of all components.

[0016] This utility model is further configured such that the gearbox also includes a first gearbox side panel, which is arranged adjacent to the first gearbox cover and the second gearbox cover in pairs. An external hexagonal oil level indicator is provided on the first gearbox side panel. The external hexagonal oil level indicator on the first gearbox side panel provides maintenance personnel with a direct and convenient window to check the lubricating oil level. During the daily operation of the square baler, maintenance personnel do not need to disassemble any parts of the gearbox; they can quickly and accurately understand the lubricating oil level inside the gearbox simply by observing the external hexagonal oil level indicator. If insufficient lubricating oil is detected, it can be replenished in time, preventing accelerated wear of gears, bearings, and other components due to insufficient lubricating oil, extending the equipment's service life, and reducing maintenance costs. Compared to some designs that require disassembling the gearbox to check the lubricating oil level, the external hexagonal oil level indicator greatly simplifies the maintenance process. Maintenance personnel do not need to perform complex operations, saving a significant amount of time and labor costs. At the same time, the quick and accurate checking and replenishment of lubricating oil can reduce equipment downtime and improve equipment availability and production efficiency.

[0017] This utility model is further configured such that the gearbox also includes a second gearbox side, which is disposed opposite to the second gearbox cover, and an internal hexagonal plug is provided on the second gearbox side. The internal hexagonal plug on the second gearbox side provides a convenient passage for cleaning and maintenance of the gearbox's interior. After long-term use of the square baler, impurities, oil stains, or wear debris may accumulate inside the gearbox. By disassembling the internal hexagonal plug, maintenance personnel can use appropriate tools to clean the inside of the gearbox, removing these contaminants, ensuring that gears and bearings operate in a clean environment, reducing wear and malfunctions caused by impurities, and extending the equipment's service life. Simultaneously, when maintenance or replacement of internal components is required, the internal hexagonal plug facilitates access for maintenance personnel. The internal hexagonal plug's design allows for easy disassembly and installation using common internal hexagonal wrenches, making operation simple and quick. Compared to some complex plug structures, it reduces the workload and operational difficulty for maintenance personnel, improves maintenance efficiency, and lowers maintenance costs. Moreover, in emergency situations, the plugs can be quickly opened for inspection or problem-solving, reducing equipment downtime and ensuring production continuity.

[0018] This invention is further configured with an elastic retaining ring between the input shaft and the input bevel gear. The elastic retaining ring provides reliable axial positioning for the input bevel gear. During operation of the square baler, the input shaft drives the input bevel gear to rotate at high speed and withstands various complex forces and vibrations. The elastic retaining ring, with its elastic properties, tightly abuts against the input bevel gear, preventing axial movement and ensuring that the input bevel gear is always in the correct position, maintaining good meshing with components such as the output gear. The tight fit between the elastic retaining ring, the input shaft, and the input bevel gear increases the connection strength between components. This reduces the risk of component loosening due to vibration, impact, or long-term operation, ensuring stable power transmission between the input shaft and the input bevel gear, and enabling the gearbox to operate reliably.

[0019] This invention is further configured such that both the first cover and the connecting plate are connected to the housing by bolts. This bolted connection simplifies the assembly process. During the production and assembly stage of the power input gearbox of the square baler, workers can quickly and accurately install the cover onto the housing without requiring complex tools or special operating skills, greatly improving assembly efficiency. Similarly, when disassembly is required, the cover can be easily removed by simply loosening the bolts with a suitable wrench or other tools, making the process convenient and quick.

[0020] The advantages of this utility model are: (1) It improves the versatility and ease of installation of the gearbox, ensuring that the equipment can better adapt to the installation environment and working requirements of different customers, while ensuring stable operation and efficient power transmission of the equipment.

The meshing design of the input bevel gear 4 and the output bevel gear 5 efficiently converts the rotational power of the input shaft 2 into the rotational power required by the output shaft 6.
