Title of invention-ong

Reit) - and wear-resistant consistent lubricants Field of application of the invention

The invention relates to low-friction and low-wear consistent lubricants which have a low friction and low-carbon shell

enable worm gears and bearings. 10

Characteristic of the known technical solutions

Consistent lubricants based on soap-thickened oils and fluid fats are known. These lubricants are usually alloyed with special anti-wear and high pressure additives. The disadvantages of these lubricants are that they are "no lubricants for life, or, if the lubricant life is sufficient, the service life of the friction elements due to fatigue wear and tear

^ O minimize processes. In addition, Jette based on soap show insufficient Walkstabilität and tend to Walker stress to 7erflussigung.

Object of the invention 25

The aim of the invention is to produce consistent lubricants, which ensure a sufficient service life of the friction with sufficient life of the lubricants.

In a RührgefaB be 400 kg Mineral oil, viscosity at 50 ⁰ C 60 mm ² / s, and submitted to 61 kg 4,4'-di- 'added phenylmethane. While stirring, the mixture is heated to 40 ⁰ C and sets this mixture consisting of 24 kg of aniline, 65 kg of primary alkylamines of chain length Q ^ to CLq and 352 kg of mineral oil raffinate mixture, which was heated to 70 ⁰ C. With constant stirring, the temperature is continuously increased to 120 G. At this temperature, the mixture is 30 kg Bariumalkylsulf onat, 8 kg oleoylsarcosine, 5 ^ S phenyl-2-naphthylamin, 5 ^ S copper octoate and 50 kg chlorinated paraffin, stirred

for 30 minutes at 120 ⁰ O and the product is cooled. The result is an olive green, homogeneous product, which has the following characteristics:
