The invention provides a dustproof grease composition used for an optical instrument and a preparation method of the composition. The dustproof grease composition comprises the following components inparts by weight: 67-95.2 parts of base oil, 3-15 parts of a thickening agent, 0.5-5 parts of a structure improving agent, 1-8 parts of a solid lubricant, 0.1-2 parts of a metal deactivator, 0.1-2 parts of an antioxidant, and 0.1-1 part of an antirust agent. The invention also provides a preparation method of the dustproof grease composition used for the optical instrument. The method provided bythe invention adopts fumed silica to thicken dimethyl silicone oil, and the structure improving agent, the solid lubricant, the metal deactivator, the antioxidant and the antirust agent are used to prepare the dustproof grease composition used for the optical instrument; and the prepared composition has excellent high and low temperature performance, colloidal stability, thermal oxidation stability, anti-wear and extreme pressure performance, sealing performance, adhesion performance and protection performance, and is suitable for long-term dust prevention and lubrication of rotating parts such as screw threads of various military and civilian optical instruments (sighting telescopes, periscopes and the like).

The invention discloses a power-closed small angle intersecting shaft gear test bench which comprises an electric motor, an auxiliary gear box, a moving platform, a rotating platform and intermeshingtest gear I and test gear II. Each part of the test bench constitutes a power-closed system to compensate for lost power. The movement of one test gear in directions of two degrees of freedom of X andY is achieved through the moving platform, the angular rotation of the other test gear is achieved through the rotating platform, the parallel shaft installation of a thickened gear and the intersection shaft installation in a certain angle range can be satisfied, and a shaft crossing angle error and a mounting distance error of the thickened gear are simulated. The contact spot, transmission error, transmission efficiency, vibration and the like of the high-speed thickening gear can be tested. At the same time, the test bench also be used for studying the influence of the shaft crossing angle error and the mounting distance error on the meshing performance of the thickened gear.

The invention provides a long-life fully synthetic industrial gear lubricant composition, which comprises (A) at least one synthetic base oil; (B) at least one anti-oxidant; (C) at least one metal passivator; (D) at least one metal detergent; (E) at least one antiwear agent; (F) at least one antirust agent; and (G) at least one friction modifier. The above lubricant composition has characteristics of high viscosity index and low pour point and can satisfy needs of industrial gear oil of 68-680 viscosity grade. The above lubricant composition has excellent anticorrosive and antirust properties, anti-foaming property, demulsibility, oxidation resistance and abrasion resistance. The antioxidation performance of the lubricant composition is particularly prominent. In addition, the lubricant composition is applicable to industrial gear and bearing lubrication system under harsh conditions of high temperature, high pressure, heavy duty and the like, and especially has outstanding performance in equipment protection, oil life and failure-free operation.

The invention relates to a rolling oil composition used for a twelve-high reversing cluster mill; the rolling oil composition belongs to the field of metallurgical steel rolling oil products, and comprises the components according to weight percent as follows: 60-70 percent of compound neopentyl polyol ester, 14-28 percent of mineral oil, 1-5 percent of phosphorus-containing extreme-pressure and anti-wear agent, 1-5 percent of sulfur-containing extreme-pressure and anti-wear agent, 2-12 percent of compound emulsifier, 1-3 percent of anti-rust agent, 1-3 percent of antioxidant and 0.01-0.5 percent of defoamer; the rolling oil composition takes the compound neopentyl polyol ester synthetic ester with excellent lubricating performance as the lubricating basic component; an oiliness agent main body with high lubricating performance and high extreme-pressure and anti-wear performance is composed by adding the scientific components of the phosphorus-containing and the sulfur-containing extreme-pressure and anti-wear agents; and the anti-rust performance and the emulsion stability are ensured by adopting the mineral oil, the anti-rust oil, the emulsifier and the antioxidant with the appropriate proportion for coordination, thereby creatively solving the contradiction between the lubricating performance and the detergence, ensuring the requirements on the lubricating performance of the quality when rolling steel plates with thin specifications, protecting the lubricating requirements of back-up bearings and ensuring the volatility and the annealing detergence under the cleaning-free condition.

The invention provides environmentally-friendly energy-saving-type heavy loading screw compressor oil. The environmentally-friendly energy-saving-type heavy loading screw compressor oil comprises 90-95% of composite base oil and 10%-5% of other additives in percentage by weight. Poly Alpha-Olefins (PAO) and dioctyl sebacate are compounded to serve as the base oil of the environmentally-friendly energy-saving-type heavy loading screw compressor oil. The environmentally-friendly energy-saving-type heavy loading screw compressor oil provided by the invention has the advantages of good operating characteristics, long service life and good biodegradability and also has effects of improving the efficiency of a screw compressor, reducing the abrasion and corrosion of a screw, effectively prolong the service life and the oil draining period of the screw compressor and meeting the requirements under special service conditions. The environmentally-friendly energy-saving-type heavy loading screw compressor oil provided by the invention is not only suitable for the requirements of various middle-heavy loading screw compressors under service conditions, and but also can meet the lubrication, cooling and sealing requirements of the middle-heavy loading sliding vane compressors.
