Planetary reducer The difference between gear reducer and gear reducer is that the basic working principle, structure and main purpose are different.
1、 The basic working principle is different
1. Planets Reducer : The basic working principle of the planetary reducer is that when the driving force on the input side drives the sun gear, it can pull the planetary gear to rotate, and follow the motion track of the inner gear ring to rotate along the center point. The rotation of the star pulls the output shaft connected to the tray to output the driving force.
2. Gear reducer: the basic working principle of the gear reducer is to use a rivet mechanism to tighten it. There is a gear driven by external driving force at the center of the ring gear, and the separate closed transmission is carried out according to the module design principle.
2、 Different structure
1. Planetary reducer: the primary transmission structure of planetary reducer is planetary gear, sun gear and inner gear ring.
2. Gear reducer: gear reducer is the combination of reducer and large reducer, including transmission device group and operating unit gear.
3、 Different main purposes
1. Planetary reducer: Planetary reducer can be used as a supporting facility part for lifting, excavation, logistics transportation, engineering construction and other fields.
2. Gear reducer: gear reducer is widely used in large and medium-sized mining, steel groups, chemical plants, seaports, environmental protection and other fields.
The advantages of planetary reducer are small size, light weight, high bearing capacity, long service life, stable operation, low noise, large output torque, large speed ratio, higher efficiency, safe and reliable performance indicators.
The defects of the planetary reducer are due to the precision of its raw materials and the rigorous production and processing methods, resulting in an increase in engineering costs and maintenance costs.
The advantage of gear reducer is no refrigeration; Use maintenance free lubricating oil for lubrication, with long service life and silent mode operation, and higher output efficiency; The shell is made of alloy steel, with high coaxiality and dynamic balance, and can be assembled on various CNC machining centers.
The defect of gear reducer is the high rigidity and high precision design, which increases the maintenance cost. The precision and torque are lower than those of the planetary reducer.
