Bridge reversed loader with the face-scraper conveyor machines ynchronous over his head face Shearer guarantee for coal mining and fully mechanized coal face of high yield and high efficiency operations. Scraper conveyor is a reprint of a special structure of the scraper conveyor powertrain and drive and scraper conveyor similar to a ramp of its fuselage and a section of the arch bridge structure and belt conveyors in the tail Paragraph above lap. 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 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 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. ZY2300belt with the design requirements for supporting the tail since the shift to achieve in the 2.3 meters 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 capacity up to 1000 tons / hour technologically advanced reliable large-scale comprehensive mining equipment supporting the excellent models. Wheel gears Wheel gears spreading to move is the most widely kind of the application spreads to move a form in the modern machine. It’s main advantage is: The 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 0.92.0.98； ④ work is dependable service life long； ⑤ Outline size outside is the small structure tightly packed. The wheel gear ； from wheel gear stalk bearings and box body decelerates a machine constituted to；；using 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. Planetary gear reducer gear reducer than the normal small size light weight high efficiency and transmission power range has widely applied gradually. At the same time its drawbacks are: material quality complex high precision manufacturing 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 structure 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 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 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. 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 machines 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 lifelong. But it spread 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 expand strongly and have already produced various structure forms and various products of power model numbers. Be close to ten several in the last years 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 part. CNC tool machine and the craft technical development pushed a machine to spread to mve structure to fly to develop soon. Bespreading 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 to move will 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 article the important trend of the development.
