Agricultural vehicle gearbox with gap bridge bearing

Abstract

The invention belongs to the field of gearboxes, and relates to a gearbox for agricultural vehicles with bridge bearings, which is used in the preparation of agricultural vehicles, and solves the problem that the eccentricity of the whole vehicle occurs in the gearbox with a single pulley, which causes excessive vibration of the pulley transmission, and the belt and the gearbox are easily damaged. The problem of damage, the use of bridge bearings can effectively reduce the vibration of the gearbox and improve the service life of the transmission belt and gearbox. The main structure includes the gearbox housing and the first shaft assembly and the second shaft assembly installed in the gearbox housing. , intermediate shaft assembly, output shaft assembly, differential assembly, clutch, pulley and bridge bearing, the front end of one shaft assembly is equipped with a clutch, the clutch is connected with the pulley through the bridge bearing, and the whole is a four-axis transmission. It can realize the reverse design of the whole machine; its overall structure is simple, the gears are arranged reasonably, the production cost is low, the gears are few, the shifting resistance is small, the processing difficulty is small, the transmission efficiency is high, the operation is easy and convenient, energy saving and environmental protection, and has good performance Economic benefits and broad market value.

Description

[0001] Technical field: [0002] The invention belongs to the field of gearboxes, and relates to an agricultural vehicle gearbox, in particular to an agricultural vehicle gearbox with bridge bearings, which is used in the preparation of agricultural vehicles. [0003] Background technique: [0004] The transmission changes the torque and speed by several pairs of gears with different transmission ratios, mainly by the deceleration and torque increase of the gear transmission. The two gears mesh with each other, and one tooth of the driving gear pushes one tooth of the driven gear. For example, the number of teeth of the driving pinion is 8, and the number of teeth of the driven gear is 16. The pinion rotates 1 circle, and the bull gear can only rotate half a circle. Therefore A pair of gear transmissions can achieve the effect of reducing the speed. At the same time, the force on the contact surface of the teeth of the two gears is equal. According to the principle of "the for...
