Abstract:
PROBLEM TO BE SOLVED: To provide a functionalized nanosphere lubricant which can be used for reducing friction or wear between all kinds of movable parts. SOLUTION: A method for manufacturing the lubricant is disclosed. This method includes provision of rigid nanospheres with a size of less than about 500 nanometers. The method further includes exposure of the nanospheres to radiant energy in order to at least partially bind a functional chemical on the surface of the nanospheres. COPYRIGHT: (C)2009,JPO&INPIT

PCT No. PCT/DE96/00344 Sec. 371 Date Aug. 25, 1997 Sec. 102(e) Date Aug. 25, 1997 PCT Filed Feb. 23, 1996 PCT Pub. No. WO96/26793 PCT Pub. Date Sep. 6, 1996In accordance with the method according to the invention, for the production of the plastics overlay, first of all a paste is made of a plastics dispersion and fillers. This paste is free of organic solvents and is applied to a sintered porous metal layer. The multilayer material thus produced is then sintered. Since the use of organic solvents is dispensed with, health risks and the risk of fire are reduced. Moreover, the composite materials produced according to the invention exhibit excellent cavitation resistance. In addition to conventional lubricant-free applications, such as bearings, these composite materials may consequently be used in particular in gear pumps and shock absorbers.
Abstract:
PROBLEM TO BE SOLVED: To provide a seizure-preventing agent applicable to a metallic part having possibility to be exposed to a high temperature of ≥500°C without using a metal such as copper, aluminum and nickel, and boron nitride; and to provide a sensor with the seizure-preventing agent applied thereto. SOLUTION: The seizure-preventing agent contains a first solid lubricant comprising one or more of bismuth and a bismuth compound, and a second lubricant comprising one or more of graphite, molybdenum disulfide and boron nitride, regulated so that the content (a) of the first solid lubricant and the content (d) of the second solid lubricant may satisfy the relations: 20 mass%≤(a)≤90 mass%, and 10 mass%≤(d)≤80 mass% with the proviso that the total of the first solid lubricant and the second solid lubricant is 100 mass%.

PROBLEM TO BE SOLVED: To provide a screw joint for an oil well pipe which exerts sufficient leakage resistance and seizure resistance even under non dope in addition to green dope. SOLUTION: The screw joint for steel pipe is composed of a pin 1 and a box 2 respectively contains contact surfaces having screw parts (1a, 2a) and metal contact parts (1b, 2b) without a screw. Sn-Bi alloy plating or Cu-Sn-Bi alloy plating is formed on at least one contact surface of the pin 1 and box 2. COPYRIGHT: (C)2007,JPO&INPIT

Abstract:
A strain wave gearing (1) has contact parts (B, C) which are the portions to be lubricated other than the teeth of an externally toothed gear (3) and an internally toothed gear (2), the contact parts being respectively lubricated with an inorganic lubricating powder having a lamellar crystal structure. The lubricating powder, during the operation of the strain wave gearing (1), is crushed between the contact surfaces of each of the contact parts (B, C) to move and adhere to the contact surfaces, thereby forming thin surface films thereon. Additionally, the powder is thinly spread by pressure and reduced into finer particles to change into a shape which facilitates intrusion into the space between the contact surfaces. By both the fine particles having changed in shape and the surface films, the lubrication of the contact parts is maintained. Neither the fine particles nor the surface films are viscous. Compared to the case where a grease or an oil is used as a lubricant, the efficiency in the low-load region and the high-speed region can be greatly improved.
