Abstract
Purpose
The purpose of this paper is to use the wavelet neural network and genetic algorithm to study the effects of polyalphaolefin, TMP108 and OCP0016 on the kinematic viscosity, viscosity index and pour point of lubricating oil.
Design/methodology/approach
Wavelet neural network is used to train the known samples, test the unknown samples and compare the obtained results with those obtained with a traditional empirical formula.
Findings
It is found that the wavelet neural network prediction value is closer to the experimental value than the traditional empirical formula calculation value.
Originality/value
The results show that the wavelet neural network can be used to study the physical and chemical indexes of lubricating oil.

Abstract
Purpose
The purpose of this paper is to analyze the force and basic rating life of angular contact ball bearings of RV reducer under the actual operating condition.
Design/methodology/approach
Force analysis of angular contact ball bearing under the actual operating condition, calculate the axial, radial load and internal load distribution, calculate the basic rating life of angular contact ball bearing under variable load conditions.
Findings
The external load has a great influence on the radial load of angular contact ball bearing, further affecting the basic rating life of angular contact ball bearing, which is a great influence on the overall life of RV reducer under the condition of high frequency and heavy load.
Originality/value
This paper provides important ideas for the design and manufacture of RV reducer in theory and experiment technology.
