In order to study the influence of rotary tillage working load on the power output transmission system, the tractor gear takes the field data collected as the input parameters of the above model, and obtains the dynamic response of the power output transmission system in different working gears through...
To verify the accuracy of the model, the simulation results are compared with the test data in the time domain and frequency domain.Figure 1 shows the time domain data of power take-off drive train test and simulation. From the simulation results, it can be seen that the lateral acceleration...
1. Model simulation During the model dynamics simulation, the input parameters of the simulation model are determined according to the actual situation, as shown in Table 1. The calculation results of tractor gear mesh stiffness are shown in Figure 1. The meshing damping of tractor gears is proportional to...
Taking LX2204 tractor as an example, the structure diagram of the transmission system of the whole machine is shown in Figure 1. In the field rotary tillage operation, part of the power output by the engine drives the wheels through the clutch, gearbox and front and rear drive axles;...
Rotary tillage operation is a typical field operation condition of tractors. During operation, 50% – 75% of the engine power is transmitted to the rotary tillage machine through the PTO shaft. The power output transmission system is the core component system for power transmission. In the face of complex...
Based on the method of lumped parameter modeling, the torsional vibration coupling model of the tractor power output transmission system is established, as shown in the figure. The model consists of engine sub model, tractor gear transmission sub model and load sub model. The engine sub model is composed...
spur bevel gears are usually formed by generating method on gear planer. On the basis of establishing the meshing coordinate system of spur bevel gear with installation error, a method is proposed to express the installation error sensitivity of the modified tooth surface of spur bevel gear by using...
With the continuous progress of agricultural mechanization, a large number of heavy tractors are used in the process of agricultural production and play an important role in the process of large-scale production. With the continuous increase of tractor tonnage, the volume of various tractor parts is becoming larger and...
In tractor gear processing, the commonly used tools include tractor gear type tools and rack type tools. In the process of tractor gear cutting tool processing, the slotting tool for processing tractor gear is like an external gear with a blade. Its blank makes meshing movement with the tractor...
Shanghai Tractor internal combustion engine Co., Ltd. studied the spline hole distortion of xf-125 primary transmission gear, carried out tests from the aspects of raw materials, heat treatment process and cold working stress, explored many influencing factors of spline hole shrinkage, and took corresponding technical measures to solve this...
