Description
Technical field
The present invention relates to Mill Technology field, specially a kind of raising godet service life reduces godet steel bonding, scratches technique.
Background technique
Machinery refers to the general name of machine and mechanism.Machinery is exactly that people can be helped to reduce work difficulty or labour-saving tool dress
It sets, as the article of chopsticks, broom and tweezers one kind can be said to machinery, they are simple and mechanical.And complicated machinery is just
It is to be made of the simple and mechanical of two or more.These more complicated machinery are usually called machine.From structure and fortune
From the viewpoint of dynamic, mechanism and machine and indistinction are loosely referred to as machinery.Machinery is derived from the Mechine and Latin of Greek
Machina, original refer to " cleverly design ", as general mechanic concept, can trace back to ancient Roman's period, primarily to
Difference and hand tools.Its " machinery " word of modern Chinese is that mechanism is English its (Mechanism) and machine (Machine)
General name.Mechanical feature has: machinery is a kind of combination of artificial component in kind.There is determining phase between mechanical each section
To movement.Therefore machine energy converter tool energy or useful mechanical work is completed, it is the most basic concept in modern mechanical principle.
This mechanical word is derived from the Mechine and Latin Machina of Greek, and earliest " machinery " is defined as ancient sieve
Horse architect Vitruvius plays machinery and the area tool Zuo Liao of effect mainly for carrying heavy goods in its works " ten books of building "
It is other: " to seem there is difference below between mechanical and tool.That is machinery is that effect occurs with most artificial and very big strength
, such as weight ballista and grape crushing machine.And tool is then that an operator is cautiously handled to achieve the goal, as scorpion shape is light
Ballista or the screw of circle such as not.Therefore tool and machinery are all to utilize upper breath of life.Ancient Greek's period is existing
Roller gear.Alexandria Leah wishes sieve and is discussing mechanical fundamental 1st century earliest, he, which thinks mechanical, to be known as
Five classes: wheel and axis, lever, coaster, wedge, spiral.The discussion of uncommon sieve reflects the feature of classic machinery.Ancient Chinese is in incense burner
In apply and can protect the parts such as the cross pivoted frame of horizontal position forever.Britain machinery scholar Willie this given at its " mechanism principle "
Definition be: " any machinery is all made of the one group of component connected with various different modes, make one component transport
Dynamic, certain movement will occur for remaining component, and the relative motion relation of the component of these components and initial movement depends on them
Between the property that connects." to strangle definition of the Lip river in its " theory movement " be that " machinery is that multiple have resistance to the mechanical scholar of Germany
The assembly of the object of power, configuration mode make it possible to that the mechanical force of nature is forced to do work by them, simultaneous
Certain determines movement." generally speaking, machinery is exactly that people can be helped to reduce work difficulty or labour-saving tool device, as chopsticks,
Broom and the article of tweezers one kind can be said to machinery, they are simple and mechanical.And complicated machinery be exactly by two kinds or
Two or more simple and mechanical compositions.These more complicated machinery are usually called machine.
