Abstract

This paper presents the problem of the operation of gear transmissions in the context of ensuring appropriate lubrication conditions. Damage caused by improper lubrication was discussed. Attention was drawn to the issue of oil contamination. Furthermore, a method for determining the thickness of the oil film of gear wheel teeth was described. There was also performed an analysis of the lubrication conditions of sample gear transmissions of the load, manufacturing technology and surface roughness.

Highlights

Root Cause Analysis (RCA) is often used by industrial plant maintenance services to identify causes of problems or incidents to eliminate them
This paper presents a method of determining the lubrication conditions of teeth in gear transmissions, which can be used by maintenance services to predict possible damage to gear teeth caused by improper lubrication conditions, as an element of the RCA analysis aimed at ensuring proper operating conditions
As a part of this study, there was presented, a possibility of using a modified calculation method based on the ISO/TR 15144-1:2014 (E) standard for determining the lubrication conditions of typical industrial gear transmissions used in drives of conveyors in industrial transport

Summary

INTRODUCTION

Root Cause Analysis (RCA) is often used by industrial plant maintenance services to identify causes of problems or incidents to eliminate them. Due to the use of the analysis of the causes of failures/damages, it is possible to effectively counteract their consequences, significantly affect the economics of the actions taken. This remark applies in particular to the operation of drive units, the service life of which is significantly limited by various forms of. This paper presents a method of determining the lubrication conditions of teeth in gear transmissions, which can be used by maintenance services to predict possible damage to gear teeth caused by improper lubrication conditions, as an element of the RCA analysis aimed at ensuring proper operating conditions. Knowledge of the parameters characterising the conditions of lubrication of the teeth allows taking preventive actions, for example, using appropriate lubricants or reducing the permissible loads
