Gear features and functions

Abstract

Gears in the mechanical equipment to achieve an integral, it is a lot of superior performance. The appropriate gear and reasonable use of transmission gears can improve equipment performance but also could prolong gear life.

Keywords

Gear, characteristics, fault, application

Wheel gear's spreading to move is a the most wide kind of the application spreads to move a form in the modern machine.Its main advantage BE

1 spreads to move to settle, work than in a moment steady, spread to move accurate credibility, can deliver space arbitrarily sport and the motive of the of two stalks；Power and speed scope

2 applies are wide；

3 spreads to move an efficiency high, η =0.92-0.98；

4 work is dependable, service life long；

5 Outline size outside the is small, structure tightly packed.The wheel gear constituted to°；；；from wheel gear, stalk, bearings and box body decelerates a machine, useding for prime mover and work machine or performance organization of, have already matched to turn soon and deliver a function of turning , the application is extremely extensive in the

modern machine.

6 Local deceleration machine much with the wheel gear spread to move,

the pole spread to move for lord, but widespread exist power and weight

ratio small, or spread to move ratio big but the machine efficiency lead

a low problem.There are also many weaknesses on material quality and craft

level moreover, the especially large deceleration machine's problem is

more outstanding, the service life isn't long.The deceleration machine

of abroad, with Germany, Denmark and Japan be placed in to lead a position,

occupying advantage in the material and the manufacturing craft specially,

decelerating the machine work credibility like, service life long.But it

spreads to move a form to still take settling stalk wheel gear to spread

to move as lord, physical volume and weight problem, don't also resolve

like The direction which decelerates a machine to is the facing big power

and spread to move ratio, small physical volume, high machine efficiency

and service life to grow greatly nowadays develops.Decelerating the

connecting of machine and electric motor body structure is also the form

which expands strongly, and have already produced various structure forms

and various products of power model numbers.Be close to ten several in

the last yearses, control a technical development because of the modern

calculator technique and the number, make the machine process accuracy,

process an efficiency to raise consumedly, pushed a machine to spread the

diversification of movable property article thus, the mold piece of the

whole machine kit turns, standardizing, and shape design the art turn,

making product more fine, the beauty turns. Become a set a machine material In 21 centuries medium, the wheel gear is still a machine to spread

a dynamic basic C tool machine and the craft technical development,

pushed a machine to spread to move structure to fly to develop soon.Be

spreading to move the electronics control, liquid in the system design

to press to spread to move, wheel gear, take the mixture of chain to spread
