Planetary reducer type selection - precision planetary gear reducer. The utility model relates to a speed reducer, which is a power transmission mechanism, which uses the speed converter of the gear to decelerate the rotation number of the motor to the required number of turns, and obtain the mechanism of large torque. Reducer is a relatively precise machinery, the use of its purpose is to reduce the speed and increase torque. It has a wide variety of models, different types have different uses.
General reducer with helical gear reducer (including parallel shaft helical gear reducer, S series reducer, bevel gear reducer etc.), planetary gear reducer, cycloid reducer, worm gear reducer, planetary frictioncvt mechanical machines. The use of commonly used reducer: slow down while increasing the output torque, torque output ratio of motor output by the deceleration ratio, but should pay attention to the speed reducer can not exceed the rated torque.
Slow down at the same time reduces the inertia of the load, the reduction of inertia is the square of the reduction ratio. We can look at the general motors have a number of inertia. The main characteristics of the worm gear reducer is a reverse self-locking function, can have a larger reduction ratio, the input shaft and output shaft is not on the same axis, not in the same plane. But generally larger size, transmission efficiency is not high, the accuracy is not high. Harmonic harmonic drive gear is controlled by the flexible components to transfer elastic deformation and dynamic movement, small volume, high precision, but the disadvantage is the soft wheel limited life, impact resistance, rigidity compared with metal, the input speed is not too high.
Because of the above factors, the VEMTE Technology Center Engineer teyan issued a new planetary gear reducer, planetary reducer compare the advantage of compact structure, small backlash, high precision, long service life, rated output torque can be large, but small series have to say, this kind of planetary gear reducer with a little expensive. It is obvious to people the transmission efficiency of planetary gear reducer, gear planetary reducer drive efficiency can be as high as 98%, compared with the bearing, the equivalent radius of curve of planetary gear reducer gear is small, so the contact area of planetary gear reducer with small, but high contact pressure.
At the same time the center ring gear of planetary gear reducer has a sun gear from the external drive between the two things, have a group by three gear planetary gear set on the packet synthesis and tray, the planetary gear set is dependent on the output shaft and the inner ring gear and the sun gear support floating in time; when the the side force driving sun gear, planetary gear can be driven by the rotation, and follow the path along the center of the inner ring gear revolves, planetary gear reducer is driven by the rotation of the output shaft connected to the power output tray. Some planetary gear reducer with small transmission ratio can not meet the large transmission ratio, sometimes need 2 or 3 sets to meet the needs of the larger transmission ratio.
由于增加了行星齒輪的數量，所以2級或3級AG旗舰厅官方网站首页的長度會有所增加，效率會有所下降，可以由使用者自由搭配。行星AG旗舰厅官方网站首页也是利用齿轮的速度转换器，将电机的回转数调整到所要用的回转数，并得到较大转矩的机构。在用于传递动力与运动的AG旗舰厅官方网站首页机构中，同時行星AG旗舰厅官方网站首页属精密型AG旗舰厅官方网站首页。行星AG旗舰厅官方网站首页型号有：60 64 70 78 80 90 110 115 120 140 142 155 160 190 242。分为直角，中空，转角三种类型。
Due to the increase in the number of planetary gear, so the 2 or 3 speed reducer will be increased in length, the efficiency will be reduced, the user can freely match. Planetary gear reducer is also the use of gear speed converter, the motor will be adjusted to the number of rotary number to be used, and get a larger torque mechanism. The utility model relates to a speed reducer which is used for transmitting power and motion. Planetary reducer models are: 606470788090110115 120140142155160190 242. It is divided into three types: right angle, hollow and corner.
