Introduction

The types of gear damage affected by lubricants include scuffing, low-speed wear, surface pitting and micropitting fatigue damage. In the design process of gears, it is necessary to consider the use of specific lubricants and the relevant characteristic parameters of oil products during service. GB/T 19936 "Gear FZG Test Procedure" describes the determination of lubricant related properties. GB/T 19936 is intended to consist of three parts. --- Part 1.Relative scuffing load-bearing capacity of oils FZG1) Test method A/8.3/90.Describes the use of type A test gears, FZG test method for relative bonding load capacity of oil products under the conditions of 8.3m/s pitch line speed and 90℃ initial oil temperature. For industrial gear and marine gear lubricants. --- Part 2.Relative bonding load capacity of high extreme pressure oil FZG step loading test A10/16.6R/120.Describes the use of A10 type test gear, 16.6m/s pitch line speed (reverse), 120℃ initial oil temperature, high extreme pressure oil relative bearing Load-carrying capacity FZG test method. Mainly used for vehicle gear lubricants. --- Part 3.FZG test method A/2.8/50 for relative scuffing load carrying capacity and wear characteristics of semi-fluid gear greases. A test method for determining the relative scuffing load carrying capacity and wear characteristics of semifluid greases in enclosed gear drives is described. Inspection procedures. 1) FZG is the Gear Research Center at the Technical University of Munich, Germany. Other FZG test methods for determining low-speed wear, micropitting, and pitting load capacity of gears are in a new stage of development and may be used in the future. Added to GB/T 19936 as an updated component. Gear FZG test procedure Part 2. Relative bonding load capacity of high extreme pressure oil FZG Step loading test A10/16.6R/120

1 Scope

This document describes a test method based on the FZG power closed test machine to determine the high extreme pressure oil by the scuffing damage on the gear surface. This document is suitable for evaluating the potential load-carrying capacity of lubricants used in the majority of vehicles and stationary installations for highly stressed cylindrical gears. Scuffing capacity. This document is not intended to assess the potential scuffing capacity of lubricants used in hypoid gears subject to high loads, such as Other methods may be used for evaluation. Note. This method is technically equivalent to CECL-84-02.
