Abstract

The invention provides an experiment device and method for measuring uniform load performance of a power dividing gear system. The power dividing gear system is erected, step-by-step loading is carried out on a single branch circuit, friction coefficients of the branch circuits are determined, the relation between output strain of the branch circuits and torque of a duplicate gear shaft is calibrated, uniform load coefficients of the branch circuits under different input torques are calculated, and a uniform load characteristic equation of the power dividing gear system is obtained. According to the experiment device and method, the defects that an existing uniform load performance experiment testing device has high requirements for erecting of a test table, needs to exert dynamic loads on a gearbox, and is high in experiment cost and long in period are overcome, and the experiment device and method for measuring the uniform load performance of the power dividing gear system are provided, wherein implementation is simple and easy, only static loads need to be exerted, the cost is low, and the experiment period is short.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to an experimental device for measuring the load-sharing performance, and also relates to a method for measuring the load-sharing performance. Background technique [0002] The power split gear transmission system can meet the requirements of high speed, heavy load, light weight and high reliability, so it is widely used in the fields of aviation, ships, weapons and heavy machinery. However, there is a risk of uneven load in the power split gear transmission system: when the input gear distributes the input power to other gears meshing with it at the same time, due to the manufacturing and installation errors and the elastic deformation of the components, there will be uneven power distribution. In this case, the branch along the way is overloaded. The core technology of the power-split gear transmission system is to achieve load sharing. At present, the most commonly used lo...
