2、anical 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, applicationWheel gears spreading to move is a the most

3、 wide kind of the application spreads to move a form in the modern machine.Its main advantage BE1 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 scope2 applies are w

5、rformance 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

6、 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 machines problem is more outstanding, the service life isnt long.The deceleration machine of abroad,

7、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 lor

8、d, physical volume and weight problem, dont 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 el

9、ectric 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, m

10、ake 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. Becom

11、e a set a machine material In 21 centuries medium, the wheel gear is still a machine to spread a dynamic basic parts.CNC 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 s

12、ystem design to press to spread to move, wheel gear, take the mixture of chain to spread to move, will become become soon a box to design in excellent turn to spread to move a combination of direction.The academics that is in spread move the design crosses, will become new spread a movable property

13、article the important trend of the development. Is the use of gear teeth of two gears meshing each other transmission of mechanical power and motion transmission. According to the relative position of the gear axis parallel to axis of cylindrical sub-gear drive, bevel gear axis intersect and cross-a

14、xis helical drive gear. Compact structure, high efficiency, long life and so on. Gear refers to the main, driven wheel gear direct, movement and power transmission devices. Of all the mechanical transmission, the most widely used gear can be used to transfer between any two axes of motion and power.

15、 The characteristics of gear is: a smooth gear transmission, the transmission ratio accurate, reliable, high efficiency, long life, the use of power, speed and size range. For example, transmission of power from small to almost 100,000 kilowatts; speeds of up to 300m / s; gear diameter from a few mi

16、llimeters to more than 20 meters. However, the need for specialized gear manufacturing equipment, the meshing noise transmission. Gear failure for the five forms, should be the appropriate design criteria established. However, tooth wear, plastic deformation and so on, as they have not been widely established and well-established engineering practice to use the calculation method a
