Abstract
Friction and wear in dynamic parts is the primary reason for energy loss in gearbox lubrication system and this can be optimized by utilizing modified lubricant. The tribological nature of gearbox system is critically affected by factors such as type of lubricant, loading & speed etc. In latest years, multiple advanced oil and modern tribological techniques & instruments have been utilized to investigate behaviour of oil like pin on disc, Fourball tester etc. This paper presents comparative investigation of oil blended with additive for two different conditions using prediction model & RSM. The design of experimentations has been conducted by using response surface methodology. The value of inputs parameters such as concentration, load & sliding velocity ranges from 0.5 to 5 %, 60 to 100 N and 0.65 to 1.5 m/s, respectively are utilized to evaluate the outcomes of coefficient of friction and specific wear rate. At the end results from Prediction equations are compared with experimental literature based outcomes to signify the effect of parameters like blend %, load & Sliding speed. The Coefficient of friction model showed 47.57 % more closer outcomes as compared to the Specific wear rate model for specific variation of unknown parameters for pin on disc setup in oil.
Highlights
Lubricants are broadly used in the manufacture and engineering zones, along with consumed in automotive and several products to advance the softness of motion between two faces of material and shrink the friction & wear factors in between these studied faces
The gearbox in wind turbine system has dominant maintenance as compared to other component .One of the key issue associated with wind turbine system is the optimal viscosity and anti-scuffing parameter reached at temp. beyond 80 0 C [1] .Friction and wear reduction is critical problem in such application due to its impact on the energy consumption and maintenance costs
Response surface methodology (RSM) is deal with the usage of factorial design .In RSM the crucial effect of a factor is well-defined as the deviation in response initiated by a variation in a level of the factor considered like Concentration or Speed or Load etc., while the other parameters are retained constant
Summary
Lubricants are broadly used in the manufacture and engineering zones, along with consumed in automotive and several products to advance the softness of motion between two faces of material and shrink the friction & wear factors in between these studied faces. The prime function of oil is to drop friction, avoid wear of material, soak up heat, avoid rust as well as reduce pollution. It’s necessary that a lubricant would be capable to circulate adequate to take in and leave generated heat. The additives present in oil advance and reinforce the life of lubricants in various lubrication systems like engine, gearbox, bearing etc
