NOVELTY - Reducer lubricant grease comprises (wt.%) cycloparaffin (50-80), fatty acid (1-5), antioxidant (0.5-1), lithium hydroxide (0.1-0.5), anti-press and anti-grind agent (1-3), ethane (1-10) and coassembled lithium hydroxide (10-40).    USE - Lubricant grease for a reducer useful for reducing abrasion and increasing life span of gear.    ADVANTAGE - The grease has high carrying capacity and anti-grating capacity. It possesses good pump-deliver performance. It provides good conglutination which can assure the enough oil and which can reduce the noise which is caused by the gear operation, improves the life-span of the gear, possesses good low temperature performance and assures the normal usage of the equipment under the condition of low temperature.    DETAILED DESCRIPTION - Reducer lubricant grease comprises (wt.%) cycloparaffin (50-80), fatty acid (1-5), antioxidant (0.5-1), lithium hydroxide (0.1-0.5), anti-press and anti-grind agent (1-3), ethane (1-10) and coassembled lithium hydroxide (10-40). The reducer lubricant grease is obtained by putting 80% of cycloparaffin, fatty acid, the co-assembled lithium hydroxide into the high speed convection contact container; refining; putting 20% of cycloparaffin; cooling; clipping and putting ethane, lithium hydroxide, and anti-press and anti-grind agent; milling; doffing the gas; and filtering into the products. An INDEPENDENT CLAIM is included for a method for producing lubricant grease of the reducer comprising:    (A) putting 80% of cycloparaffin, fatty acid, and the co-assembled lithium hydroxide into the high speed convection contact container and puddle, under 80 degrees C;    (B) increasing the temperature to 100-150 degrees C and then to 210-220 degrees C; keeping the temperature for 15-30 minutes;    (C) putting the mixture into a middle kettle and putting 20% of cycloparaffin; cooling; lowering the temperature to 140-160 degrees C, to 100-130 degrees C and then to 80-100 degrees C;    (D) putting ethane, lithium hydroxide, and anti-press and anti-grind agent; and    (E) leaching.    DESCRIPTION OF DRAWING(S) - The drawing is a flow chart of a method for producing lubricant grease of the reducer (Drawing includes non-English language text).
