introduction：Thickening agent is composed of a network of soap fibers，It functions like a container for lubricating oil。Fill the space with lubricating oil，Its like a small hole in the sea filled with water。 If a sponge is squeezed，The water will run out.，The grease will act like a sponge，The oil is expelled by pressing，But bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，Used to reduce the coefficient of friction in the process of power transmission and keep the center of the shaft fixed

introduction：Chromium-nickel austenitic steel has many advantages，But in recent decades due to nickel-based heat resistant alloys with nickel20％Following the extensive development and application of thermal strength steels，As well as the increasing development of the chemical industry, the demand for stainless steel is increasing，Nickel deposits are small and concentrated in a few areas，Therefore, there is a contradiction between nickel supply and demand in the world。So in the field of stainless steel with many other alloys（Such as large casting and forging steel、Tool steel、Heat strength steel, etc）In the，Nickel in particular Resources are relatively scarce in the country，The scientific research and production practice of nickel saving and nickel substitution with other elements have been extensively carried out，In this regard research and

introduction：Our country is a big coal producing country in the world，To meet the rapid increase in demand for coal，The installed power of many coal mining machines has doubled，Therefore, the requirements for mechanical transmission parts are getting higher and higher，The traditional transmission structure of fixed shaft gear train can not meet the new working requirements，It is imperative for coal mining machinery to adopt planetary gear transmission。The planetary gear transmission of the planetary reducer has the characteristics of power distribution，Each center wheel can form a coaxial drive，And the internal meshing gear pair is used reasonably，So it can be small、Light weight、Compact structure and strong bearing capacity。In addition，Symmetry of planetary gear transmission structure，Also make
