在输出轴上安装传动件时，不允许用锤子敲击，通常利用装配夹具和轴端的内螺纹，用螺栓将传动件压入，否则有可能造成减速机内部零件的损坏。
When driving parts are installed on the output shaft, it is not allowed to knock with hammers. Usually use assembly jig and inner thread of shaft end to press the tran***ission parts into bolts with bolts, otherwise, it may cause damage to internal parts of reducer.
允许输入法兰：
不能大于或小于临级减速机的标准尺寸，如减速机PLE80?的标准法兰为80mm,其临级的减速级是PLE60?和PLE120，PLE80?允许法兰不应小于60mm,也不能大于120mm。
Allow input flange
It can"t be greater than or less than the standard of the reducer. For example, the standard flange of reducer PLE80 is 80mm, and the deceleration stage of its reducer is PLE60? PLE120, PLE80?Afterrunningfor200~300hours,thefirstoilchangeshouldbedone。 The maximum allowable flange should not be less than 60mm, nor greater than 120mm.
减速机的作用
1)降速同时提高输出扭矩，扭矩输出比例按步进电机输出乘减速比，但要注意不能超出减速机额定扭矩。
2)速同时降低了负载的惯量，惯量的减少为减速比的平方。大家可以看一下一般电机都有一个惯量数值。
The function of the reducer
1) reduce the speed and increase the output torque at the same time. The ratio of the torque output to the multiplying and decelerating ratio of the stepper motor output, but we must be careful not to exceed the rated torque of the reducer.
2) speed reduces inertia of load at the same time, and inertia reduces to the square of deceleration ratio. As you can see, general motors h***e an inertia value.
减速机内部齿轮的齿距和压力角 小齿距能保证有较多的轮齿同时接触，齿轮重叠增多，减少单个齿轮挠曲，降低传动噪声，提高传动精度。较小的压力角由于齿轮接触角和横六角空心砖模具向重叠比都比较大，因此运转噪声小、精度高。
The tooth distance of the gear in the reducer and the ***all pitch of the pressure angle can ensure that there are more teeth at the same time, the overlap of the gear is increased, the deflection of the single gear is reduced, the tran***ission noise is reduced, and the tran***ission precision is improved. The ***aller pressure angle is due to the larger contact ratio between the gear contact angle and the six corners of the hollow brick mold, so the running noise is ***all and the accuracy is high.
