Parts of the distributor (Manifold of Metering Device, or Distribution Manifold) that distribute or fix the lubricant to the oil distributor

Single-line distributor (Metering Device With Injectors) is a distributor consisting of an oil circuit board and one or several single-line oil feeders. All parts can also be combined into one part

Tribology (Tribology) studies the theory and practice of the dual surfaces that interact with each other in relative motion.

Friction impedes the occurrence of tangential relative movement between the surfaces of two objects. Friction is also commonly used to express friction.

Wear When the surface of the object moves relatively, the material on the working surface is continuously lost or the residual deformation occurs. The wear process mainly occurs due to the mechanical, chemical and thermal effects between the dual surfaces.

Lubrication uses lubricants to reduce friction and wear or other forms of surface damage between two frictional surfaces.

Tribophysics is the branch of physics that deals with the interaction surface of relative motion.

Tribomechanics is a branch of mechanics that studies the microscopic and ultramicroscopic processes of solids under the influence of mechanical energy.

Tribochemistry is a branch of chemistry that studies the reaction of mechanical, physical, and chemical changes in the surface layer of a dual surface layer caused by relative motion. The focus of friction chemistry is to study those chemical reactions between the lubricant components and the friction surface that interact with each other.

The friction pair (Rubbing Pair) makes the two components contact with each other and have a relative motion connection.

External Friction is the same as friction.

Internal Friction Friction caused by the relative displacement between parts in the same object.

Static Friction (Static Friction) Two objects produce microscopic pre-displacement under the action of external force, that is, elastic deformation and plastic deformation, etc., but the friction of relative motion that has not yet occurred. The static friction at the moment when the relative motion is about to start is called the limit static friction and the maximum static friction. The friction coefficient at this time is called the static friction coefficient. .

Kinetic Friction (Kinetic Friction, Dynamic Friction) Friction between two surfaces in relative motion. The friction coefficient at this time is called the dynamic friction coefficient.

Coefficient of Friction (Coefficient of Friction) The ratio of the friction force that hinders the relative motion of two objects to the normal force that compresses the two objects

Sliding Friction (Sliding Friction) Friction when two contacting objects have different speeds and/or directions.

Rolling Friction (Rolling Friction) The friction point of two contacting objects with the same speed and direction.

Spin Friction Friction when two contacting objects rotate relative to each other around the normal of their contact surface.

Dry Friction Friction between two objects when there is no lubricant in any form. Strictly speaking, there is no other medium such as moisture and natural pollution sources on the contact surface during dry friction.

Boundary Friction Friction and wear characteristics between two solid surfaces in relative motion are mainly determined by the surface properties and the properties of the boundary layer lubricant of the very thin layer, and the friction condition that has little relationship with the volume viscosity characteristics of the lubricant film .

Fluid Friction Friction when two solid surfaces moving in relative motion are completely separated by a liquid lubricant with volume viscosity characteristics, that is, friction caused by the viscous resistance or rheological resistance of the liquid.

Lubricated Friction Friction between two solid friction surfaces with any form of lubricant.

Mixed friction (Mixed Friction) Friction under the mixed condition of dry friction, boundary friction or fluid friction between two solid friction surfaces, also known as semi-dry friction or semi-fluid friction.

Unlubricated Friction (Unlubricated Friction) There is no lubricant in any form between the friction surfaces of two solids, but it may not be a friction under completely dry conditions.

"Stick-Slip" is also called stick-slip. It refers to the friction pair that performs relative motion when its driving speed and load are kept constant, and sometimes jumps or pauses, or the phenomenon of uneven movement. Also known as "stick-slip" phenomenon. The friction force of "creeping" has the characteristic of decreasing with the increase of the moving speed. The relationship between the vibration speed and the moving speed generates the alternating friction force that maintains the self-vibration.

Friction Duty (Friction Duty) The specification of the load, speed, ambient temperature medium, surface state and other parameters of the friction pair during relative movement. Working condition
