1-lubrication of large girth gears
girth gear transmission is a common transmission method in the raw material processing industry, widely used in large equipment in the electric power, mining, cement, steel, chemical and paper industries. in the cement industry, rotary kiln and steel ball mill and other equipment using girth gear transmission.
the main features of girth gear transmission are: heavy load, low speed, large structure size and high tooth surface roughness, harsh working conditions (such as dust, high temperature, etc.), tooth surface under high stress, in addition to rolling friction in the knuckle position, there is also a lot of sliding friction in the process of its meshing, girth gears are often in a mixed friction state (start, stop instant, excessive shear, impact load, etc.). therefore, a suitable adhesive lubricant is needed.
adhesive lubricant should have suitable viscosity base oil, but also have suitable proportion of pressure (ep) additives and solid additives with laminar dotted crystal structure (for example: graphite), as well as suitable thickener and some other special additives, so as to meet the comprehensive requirements of fluid lubrication and boundary lubrication as well as emergency lubrication.
to ensure that open gears obtain good load carrying capacity and smooth transmission, the correct machining and manufacturing of gears, the accurate alignment of the transmission (end jump, diameter jump, tooth top clearance, tooth side clearance, etc.), the correct implementation of a series of work procedures for initial, break-in and operational lubrication systems, the selection of suitable high adhesion lubricants and reasonable lubrication methods are all indispensable factors.
good load transmission means that the stress is evenly distributed over the entire tooth surface, but for open gearing it is difficult to achieve this ideal condition even with the most sophisticated manufacturing techniques and the most rigorous alignment procedures. uneven load distribution can lead to damage such as scuffing, wear, plastic deformation, pitting and even tooth breakage on tooth surfaces under severe operating conditions. users can effectively reduce these damages by selecting suitable adhesive lubricants and reasonable lubrication methods, thus extending equipment life.

2 - lubrication of rotary kiln wheel belt
normally, there is a difference in thermal expansion rate and rigidity between the kiln body and the wheel belt of rotary kiln, so the inner diameter of the wheel belt is designed in advance to be larger than the outer diameter of the kiln body. in this way, the contact surface between the pad and the wheel belt produces rolling displacement during rotation, and the normal amount of rolling displacement is related to the diameter difference between the kiln body and the wheel belt.
