In the back-alley in the coal face when the machine goes to reprint its arch bridge and all of the aircraft ended the lap belt conveyor stack of position limits, a
4、 retractable belt conveyor shortened ride Next length of the belt conveyor for the development of the shift to home-unloading nose reproduced below, can be reproduced with the face of the advance goes forward. Reproduced large-scale machine is fully coal face with the equipment supporting the use of
5、 the Gate transmission, reproduced equipment, to complete the face conveyor sent to the coal transportation, transit facilities to follow up on the conveyor belt of tasks and to provide the appropriate means of connection. ZY2300 belt with the design requirements for supporting the tail since the sh
6、ift to achieve in the 2.3 metres of the overall mobile rather than demolished shift belt machine. ZY2300 belt and the tail of the shift can be more easily cope with belt-regulation, enhance the belt-and-reproduced with the coordination. This reprint of MG300/700-WD and supporting the use of conveyor
7、, capacity up to 1,000 tons / hour, technologically advanced, reliable, large-scale comprehensive mining equipment supporting the excellent models. Wheel gears Wheel gears 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:
8、The 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 applies are wide； spreads to move an efficiency high, =0.92.0.98； work is dependable, service life long； Ou
9、tline 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 ,
10、 the application is extremely extensive in the modern machine. Planetary gear reducer gear reducer than the normal small size, light weight, high efficiency and transmission power range, etc, widely applied gradually. At the same time its drawbacks are: material quality, complex, high precision manu
11、facturing, more difficult to install, design complex calculations than the average speed reducer. but on the planet as people drive technology further in-depth understanding and knowledge as well as the introduction of foreign planetary transmission and absorption of technology to drive the structur
12、e and contain its way are constantly improving, and continuously improve the level of production technology, can produce a better planetary gear reducer. According to a general load of gear strength, geometric dimensions of the design calculation, and then to carry out transmission ratio conditions,
13、 concentric condition, the assembly conditions, design and calculation of the adjacent conditions, thanks to the number of planetary gear transmission, also must be contained institutions and the design of floating volume calculation. Planetary gear drive according to the composition of basic enough
14、 pieces can be divided into: 2KH, 3K, and KHV are three. If the meshing of gears by the way, can be divided into: NGW-type, NN-based, WW-type, WGW type, NGWN type and N-type and so on. I designed planetary gear is 2KH NGW planetary transmission type. Local deceleration machine much with the wheel ge
15、ar 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 machines pr
16、oblem is more outstanding, the service life isnt 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
17、it spreads to move a form to still take settling stalk wheel gear to spread to move as lord, 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 se
