Abstract

The invention discloses an inner gear ring of a tractor gearbox. The inner gear ring of the tractor gearbox comprises an inner gear ring body; a central through hole is formed in the inner gear ring body; an inner flange is arranged at one end of the central through hole; an inner transmission gear is arranged at the other end of the central through hole; the inner diameter of the center hole of the inner flange is smaller than the tip diameter of the inner transmission gear; and an oil groove allowing lubricating oil to pass is formed in the end surface, located on the side of the inner flange, of the inner gear ring body. According to the inner gear ring of the tractor gearbox, the inner transmission gear is arranged on one side of the central through hole so that the requirement of gear transmission can be met; and the oil groove allowing the lubricating oil to pass is formed in the end surface of the inner gear ring body so that the lubricating oil can be ensured to pass and can lubricate other transmission mechanisms of the gearbox, and the lubricating performance of the gearbox can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to an inner ring gear of a tractor gearbox. Background technique [0002] The gearbox is composed of gears and shafts. It produces variable speed and torque through different gear combinations. Its functions mainly include: 1. Change the transmission ratio; 2. When the engine rotation direction remains unchanged, the car can run backwards; 3. Use neutral gear , to interrupt the power transmission so that the engine can start, idle, and facilitate the transmission to shift gears or perform power output. The existing internal ring gear of the tractor gearbox generally only has internal teeth in the ring gear, although it can meet the meshing requirements, but because the lubricating oil cannot pass through, there is a defect of insufficient lubrication in other parts of the gearbox. Contents of the invention [0003] In view of this, the object of the pr...
