Technical Field

[0001] This utility model relates to the field of gearbox technology, specifically a gearbox for power output in tractors. Background Technology

[0002] A type of gearbox for tractor power output is widely used in agricultural machinery such as tractors to transmit engine power to implements. Under long-term high-load, dusty, and frequent start-stop conditions, existing gearboxes generally suffer from poor reliability and difficult maintenance.

[0003] Traditional structural designs have significant drawbacks: the power output shaft and support bearings are small in size and have weak load-bearing capacity, making them prone to fatigue damage; the housing strength is insufficient, making it susceptible to cracking and deformation; the compact internal structure and numerous accessories necessitate complete disassembly for maintenance, resulting in complex procedures, long processing times, and making it difficult for ordinary users to repair themselves. Once a malfunction occurs, not only are repair costs high, but the efficiency of agricultural operations during busy seasons is also severely affected.

[0004] Therefore, there is an urgent need for a gearbox for tractor power output that is structurally sound, easy to assemble and disassemble, quick to maintain, and highly durable, in order to solve the pain points of "difficult maintenance, long time consumption, and high cost" in the existing technology. Summary of the Invention

[0005] In view of the above situation and to overcome the existing defects, this solution provides a gearbox for tractor power output.

[0006] The technical solution adopted by this utility model is as follows: A gearbox for tractor power output includes a device cover, a device bottom shell, threaded holes, a bearing placement groove, and a female-female connection port. The top of the device cover has multiple threaded holes, each of which is threaded. The top of the device cover has a bearing placement groove and a female-female connection port. The bottom shell is located at the bottom of the device cover. A gear placement groove is located at the adjacent ends of the device cover and the device bottom shell. A screw fixing plate is fixedly connected to the lower inner wall of the gear placement groove.

[0007] Preferably, a sealing ring is provided at the bearing placement groove.

[0008] Preferably, the gearbox is a rear-mounted gearbox, specifically installed at the rear end of the tractor.

[0009] The beneficial effects of this utility model are as follows: This device adopts an enlarged bearing design, which improves load-bearing capacity, significantly enhances durability, and reduces the failure rate. Furthermore, this device is an independent structure, which does not damage the original foundation of the main unit, making installation convenient. During maintenance, the power output shaft can be directly inspected from the rear without major disassembly, saving time and effort. At the same time, the modular design simplifies maintenance, allowing users to perform repairs at home, truly achieving easy installation, easy repair, durability, and reliability.
