6、齿加工齿轮的数量占齿轮总数量的百分比提高，使得整个传动的各种性能大大提高所致。 The gear reducer is composed of one-stage spiral bevel gear and one-stage planetary gear in terms of drive. Compared with three-stage common spiral bevel gearcylindrical gear reducer, the gear reducer proper is featured by small volume, light weight, stable dr

8、速机主要由以下几部分组成。The gear reducer is structured as follows：2.1伞齿轮传动部分Driving part of bevel gear 减速机输入级为一对克林贝尔格螺旋伞齿轮。大小齿轮均采用渗碳淬火钢进行制造，并采用硬齿面加工方法加工而成，强度很高。小伞齿轮和大伞齿轮均通过轴承座装入下壳体中，两轴承座法兰下设有调整垫，用于调整齿轮副接触区的位置和齿侧间隙。 The input stage of the gear reducer is a couple of KLINGELNBERG extension epicycloidal spiral be
9、vel gears hardened-steel and machined by means of hard tooth surface processing, which presents high strength. Bull gear and pinion gear are mounted in lower casing via bearing seat. There are adjusting spacers beneath flange of two bearing seats, which are designed to adjust the position of gears s
10、ub-contact area and the gap of flank of teeth. 2.2行星级齿轮传动部分Driving part of planetary-stage gear 行星级齿轮传动主要由太阳轮、行星轮、内齿圈等组成。Planetary-stage gear is mainly composed of sun wheel, planetary gear, internal ring gear, etc. 工作时太阳轮浮动，以便使其轮齿同时和三个行星轮均匀接触，达到均载目的；行星轮安装在行星架上，在绕自身轴线传动的同时，也随行星架一齐转动。内齿轮安装在壳体中固定不动。太阳
11、轮，行星轮均为渗碳淬火后磨齿齿轮，内齿轮为调质齿轮。When in operation, the sun wheel is floating so as to allow its gears to uniformly contact 3 other planetary gears for uniform loading. Planetary gears are mounted on the planetary frame and is rotating with the planetary frame while driving around his own axis. Internal ge
12、ar is mounted in the casing without movement. Sun wheel and planetary gear are made of post-carburized hardened grinding teeth gear while internal gear is of quenching and tempering gear.2.3齿轮联轴器Gear coupling 该减速机在两级齿轮传动之间设置了鼓形齿联轴器，其作用是连接两级齿轮之间的传动。由于齿轮联轴器的内齿套也随行星级中的太阳轮一起浮动，所以联轴器齿轮也采用合金钢材料来制造。 There
13、is a barrel-shaped gear coupling between two-stage gear drive for the gear reducer proper, the purpose of which is to link the drive for two-stage gear. Since the internal teeth sleeve for the gear coupling is floating with the sun gear in the planetary-stage, coupling gear is made of alloyed steel.
14、2.4平面滑动推力轴承Plane sliding thrust bearing 为了承受磨煤机工作中的动静载荷，减速机上部设置了平面滑动推力轴承，靠推力盘旋转在推力盘和推力瓦之间产生动压润滑油膜进行工作。In order to sustain dynamic and static loading of coal mill in operation, the gear reducer is equipped with plane sliding thrust bearing at the upper part, which may generate dynamic pressure lubric
15、ating oil film between thrust disc and thrust bushing by means of rotation of thrust disc. 推力盘为钢制材料制成，推力轴承瓦面为塑料瓦材料制成。由于该轴承靠建立正常的润滑油膜而工作，轴承材料硬度又很低，所以不能在磨煤机加载而又无煤的情况下使用。在使用盘车装置时，要全部放松（对于变加载式磨煤机最好将磨辊抬起）磨煤机载荷来进行，以保证轴承的安全性。Thrust disc is made of steel and thrust bearing bushing surface is made of plastic
16、 bushing. Since the bearing is working by establishing proper lubricating oil film and there is low hardness of bearing material, it can not be used while loading coal mill and with no coal. When using barring gear, it is advisable to fully unload coal mill (regarding adjustable loading coal mill, p
17、referably lift mill roller) so as to protect the safety of the bearing.2.5滚动轴承Roller bearing 本减速机均采用SKF和NSK轴承装配，和平面滑动轴承一样要求润滑油保证质量和清洁度。The gear reducer is equipped with SKF NSKbearing requiring assured quality and cleanliness for lubricant like plane sliding bearing.2.6壳体Casing 减速机采用上下箱分开式壳体，目的是为了方便
18、下箱体中零部件损坏时的维修。上下箱体强度和刚度好。上箱体设有两个进油口和二个推力轴承回油观察孔，下箱体设有二个回油口，二个检修门和二个油位观察口。The gear reducer is assembled with upper and lower split-type casings, the purpose of which is to facilitate repair on damaged components in lower casing. Upper and lower casings good strength. In upper casing, there are two oi
19、l filling ports and two observation holes for oil return of thrust bearing. In lower casing, there are two oil return ports, two maintenance doors and two oil level observation holes.2.7润滑与冷却Lubrication and cooling 为了保证齿轮和轴承在运转中得到可靠地润滑与冷却，减速机选用了硫磷型极压工业齿轮油作为润滑与冷却介质，并采用过滤精度很高的润滑站对减速机提供合适温度的润滑油。减速机内部各润
20、滑点的供油量是通过计算与试验确定下来的，可以充分满足所有存在相对运动零件的使用要求。同时进油管安装有溢流阀以控制低油温时（25）最高油压不超过允许值0.58MPa，在正常油温下（4060）溢流阀不工作。In order to make sure that gears and bearings are properly lubricated and cooled during operation, we utilize sulfur/phosphorous type extreme pressure industrial gear oil as lubricating and cooling m
21、edia for the gear reducer and also choose lubricating station with fine filtering to provide lubricating oil of proper temperature for the gear reducer. The quantity of oil supply to each lubricating point inside the gear reducer is determined based on calculation and test, which can satisfy the req
22、uirement of operation for all parts with relative motion. whist the oil feeding pipes is equipped with overflow valves to control the maximum oil pressure not exceeding allowed valve at low oil temperature(25). The overflow valve can not work at normal oil temperature(40-60)3安装Installation 因为减速机既是磨煤
23、机的驱动部件，又是磨煤机中主要转动部件（如磨辊、磨环等转动件）的最初安装基准，同时又是磨煤机碾磨加载力的支撑体，所以减速机的安装正确与否严重关系到磨煤机的工作性能问题。因此，在整个磨煤机安装过程中，必须有懂得减速机安装技术的工程师和技术工人（或者是经过专门技术培训的这些人员）一起进行。Since the gear reducer is not only the driving part for coal mill, but the original erection benchmark for the main rotating part (such as mill roller, mill
24、ring, etc.) for coal mill and the support for loading force of grinding of coal mill as well, the correct erection of the gear reducer has a close relation with its performance. Therefore, the erection of the gear reducer must be carried out by experienced engineers and technicians (or people subjec

26、： 由于磨机粉磨装置的重量和粉磨压力都将通过齿轮箱传到基础底座上,所以整个齿轮箱必须放置在基础底板的整个平面上.将齿轮箱安装在基础底板上时,整个基础底板必须经过严格的水平检验,基础底板的水平误差不能超过0.05mm/M,并且要仔细地清洗齿轮箱和基础底板的结合面,然后用润滑脂涂抹基础底板,以便在安装齿轮箱时能够移动之.Since the weight and pulverizing pressure of mills pulverizing unit are traveling to soleplate via gearbox, the whole gearbox has to be laid
27、across the plane of soleplate. When installing the gearbox onto the soleplate, the whole soleplate must be carefully inspected horizontally with horizontal error not more than 0.05mm/M. Meanwhile, thoroughly clean the joint surface between gearbox and soleplate before applying grease to the soleplat
28、e so as to move it when installing the gearbox.在基础底板上安装齿轮箱Install gearbox onto soleplate首先确定基础底板上磨机中心线的位置,然后利用齿轮箱下部的起吊孔将其起吊到预定位置,仔细调整减速机位置，使减速机底板上中心刻线对准基础底板上磨机中心线，然后通过箱体底板上的8个螺栓孔用螺栓将齿轮箱紧固在基础底板上。First of all, determine the position of mills central line on the soleplate and then lift the soleplate to
29、 the expected position by means of 4 lifting eyes on the lower part of gearbox. Carefully adjust the position of gear reducer to allow its central line on the base plate to align with mills central line on the soleplate. And then tighten the gearbox to the soleplate with 8 bolts on casing base plate
30、.3.1 清理与检查Clean and check 安装前用煤油擦洗掉减速机底面，输入轴颈，输出传动法兰端面上的防锈漆和其它杂质污物等。检查并排放干净减速机内部的残留润滑防锈油。Get rid of corrosion and other impurity with kerosene oil from gear reducers bottom, neck of input shaft and output drive flange end surface. Check and empty residual rust-preventative oil inside the gear reduce
31、r. 为保证减速机精确定位，修磨因不慎而造成的减速机底面上和基础台板表面上的凸痕等。为防止安装后并且在长期使用情况下，减速机底面与台板表面锈蚀在一起，应在台板表面上均匀涂以一层薄薄的MoS2润滑脂。In order to ensure the accurate alignment of the gear reducer, grind and remove the imprint marks unintentionally left on the gear reducer surface and foundation bedplate surface. In order to prevent c
32、orrosion of gear reducer surface and bedplate surface occurring during operation after installation, apply a uniform thin film of MoS2 lubricating grease to bedplate surface.注意！减速机输入轴迷宫防锈包装密封，输出传动法兰迷宫防锈包装密封，呼吸器上的防锈包装胶带最好在减速机启动前拆除，以免安装周期过长，内部零件发生锈蚀。Caution：It is advisable to remove the labyrinth seal for input shaft and output drive flange, rubber tape on respirator before startup of the gear reducer so that internal parts can be free of corrosion due to long-term erection
