汽车专业英语_3_AUTOMOTIVE_LUBRICATION_SYSTEM解读
How successful the lubrication system is in performing all these functions depends on a number of factors and conditions. There must be an adequate supply of good-quality lubricant delivered to all moving engine parts under sufficient pressure to provide hydrodynamic lubrication for rotating parts and oil adhesion to surface subject to sliding friction.

Mobilgear SHC 46M 高技术、超高粘度、合成开式齿轮油说明书
Product Data Sheet Mobilgear SHC 46MHigh Technology, Ultra High Viscosity,Synthetic Open Gear Oil Product DescriptionMobilgear SHC 46M is a speciality ultra high viscosity lubricant primarily intended for use in heavily loaded, low and medium speed gears where boundary lubrication conditions prevail.Mobilgear SHC 46M is formulated from wax-free synthetic base stocks which have exceptional oxidation and thermal properties and remarkable excellent low-temperature fluidity. The combination of a naturally highviscosity index and a unique additive system enables the product to provide outstanding performance under severe high and low temperature operating conditions. The base stocks have inherently low traction properties which result in low fluid friction in the load zone of non-conforming surfaces such as gears. Reduced fluidfriction produces lower oil operating temperatures and improved gear efficiency.Mobilgear SHC 46M exceeds Falk minimum viscosity requirements for intermittent lubrication of gears.Mobilgear SHC 46M does not contain any solvent.BenefitsMobilgear SHC 46M offers the following benefits:•Extended gear life resulting from outstanding load-carrying, anti-wear and tackiness properties derived from proprietary thick film lubrication•Reduction in pump replacement costs due to their pumpability at ambient temperature•Improved safety gear efficiency and lower operating temperatures arising from low traction properties •Reduced lubricant consumption and disposal costs•Absence of hard-packed deposits and the elimination of the need for gear cleaning with subsequent reduction in downtime and maintenance costs•Improved safety through absence of solvent•Easier distribution/meteringApplicationMobilgear SHC 46M is primarily recommended for open gears where asphaltic, diluent-containing lubricantshave historically been used. Mobilgear SHC 46M is also recommended for the replacement of semi-fluid greases.Mobilgear SHC 46M can be applied with conventional single line or dual line spray systems without costly circulation system modifications. It is pumpable at temperatures as low as +6°C but, at lower temperatures, the product may have to be heated to achieve the proper spray distribution pattern.Health and SafetyBased on available toxicological information, it has been determined that this product poses no significant health risk when used and handled properly.Details on handling, as well as health and safety information, can be found in the Material Safety Data Bulletin which can be obtained through Mobil Oil Company Ltd., by telephoning 01372 22 2000.Typical physical characteristics are given in the table.

专利名称：Lubrication System for a Gear Box andAssociated Methods发明人：Michael E. Konruff,Chuong Nguyen,CharlesRichard Russell,Jack Dean Asher,JohnWilliam DeJong, II,Thomas F. Esterle申请号：US14477166申请日：20140904公开号：US20160069446A1公开日：20160310专利内容由知识产权出版社提供专利附图：摘要：A lubrication system for a gear box has a backing member. The backing memberis configured to allow mounting of a plurality of lubrication components on the backing member. One of the lubrication components comprises a pump configured to pressurize lubricating oil for the lubrication system. The pump has a suction and discharge. The pump suction is removably connectable to the gear box and the pump discharge is removably connectable to piping that is configured to communicate with the gear box. The backing member has a lifting mount arranged along its length and width that corresponds to a center of gravity of the backing member with the lubrication components mounted thereto. The lubrication components are modular and may be replaced and installed as necessary on the backing member. Multiple like lubrication systems may be provided, and removed and installed on the gear box as needed for maintenance.申请人：Baldor Electric Company地址：Fort Smith AR US国籍：US更多信息请下载全文后查看。

Lubricating System
Dccessful operation of any engine or machine and its trouble free life depends on-effective lubrication which involves the formation and maintenance of a lubricating oil film between the moving parts. The marine diesel engine is no exception and considerable thought has gone into the problem of the lubrication of its many parts with their widely varying operation conditions. In addition to providing lubricating films, oils used in marine diesel engines have to remove heat from oil cooled pistons, neutralize acidic products of combustion, cleanse hot moving parts of carbonaceous deposits, resist oxidation and wash away wear detritus. The development of oils has kept pace with the increasing demands made by the steady rise in powers produced by modern marine diesels. The selection of oil from the commercially available range depends to a great extent on the operating conditions, the design of the engine and the type of fuel to be burned. Large marine diesel engines of cross head construction generally have two systems of lubrication: a total loss system feeding the cylinders and a circulating system lubricating the running gear and cooling the pistons.
