Select xuanze) Models with the following three parameters: parameter: Enter turnhn(r/ min nv(r/ min) Enter power (i.e. how much of the work the object does in unit time)p kw) 
　　Note:
　　i. Choice (I) xuanze) Models with the following three parameters: parameter)：
　　1. Enter turnh(r/ min)
　　2. Passage ratio i or output speed nv(r/ min)
　　3. Enter power (i.e. the amount of work done by the object in unit time)p kw)
　　2. If the rate of rotation of the input axis is different, the power of the movement (i.e. the amount of the work done by the object in unit time) should also be changed, so that special attention should be paid when driven by a transformer motor or a transformer device (A/AC.254/5/Add.1 and Corr.1). attention) Choosing the machine number () xuanze (i) The conditions of work shall first be determined; Whether the constant power (i.e. how much the object does in unit time) or the rectangular (i.e. how much the object does in unit time) is the constant power, selects the machine number at the lowest rate and, if rectangular, selects the machine number at the highest rate.Hard-noodle gear brakes.To achieve a particularly low output rate, this can be achieved by connecting two gear-reducing machines. When this is used, the power of the configured power must depend on the speed-reducing machine ' s maximum output twist, not on the power of the machine to calculate the speed-reducing machine ' s output twist.Planetary gear decelerator.It is a revolving institution that has been widely used in China, East China, for the introduction of cranes to towers, in metallurgy, mines, cranes, transport, cement, construction, chemicals, textiles, printing, pharmaceuticals and so on.
　　iii. Eight hours per day at a flat load and a situation factor of k = 1.0, while selecting (xuanze) When the number is determined, the speed-reducing machine is determined. Retarder The input power (i.e., the amount of work done by the object in unit time) should also be taken into account. consider The nature of the load, the working conditions and the driving power source to determine the work () Condition coefficient k. The gear-reducing machine is a revolving body that is widely used in China, the East China region, and for the introduction of cranes to towers. It is widely used in the fields of metallurgy, mines, cranes, transport, cement, construction, chemicals, textiles, pigmentation and pharmaceuticals.
　　Speed-reducing machines Retarder) The input power (i.e. the amount of the work performed by the object during the unit time) is calculated according to the following formula:
　　P: Speeding machines Retarder) input power (i.e. the amount of work done by the object in unit time)     
　　k: Work(s) Condition coefficient    
　　p: Input power required for driven machinery (i.e., the amount of work done by the object in unit time)  
　　Speed-reducing machines Retarder efficiency () efficiency)
