Planetary Gearboxes

PLF Economic Flange Output Planetary Gearbox

A planetary gearbox, also introduced as an epicyclic gearbox, is one of the most interesting forms of device present within motion control. They are typically employed in automotive as an essential component of automatic transmission applications. Planetary Gearboxes are a form of the gearbox where the output and input both have the same center of turning. This means that the center of the input gear rotates around the center of the output section, and the output and input shafts are aligned.
The design of the planetary gearbox is relatively simple, including a central sun gear, an outer ring (also known as an internal gear since its tooth face inward), a carrier, and the planetary gears. Input power to the sun gear results in spinning. The mesh of planetary gears with the sun gear has a standard, and as the sun gear rotates based on this, so the planetary gears turn according to their axes.

As one of the leading planetary gearbox manufacturers, suppliers, and exporters of mechanical products, We offer planetary gearbox and many other products. Please get in touch with us for details.

Introduction of PLF Economic Planetary Gearboxes

PLF series precision speed reducers belong to a cost-optimized inline planetary gearbox with flange, which offers an economical solution for your motion control or transmission system needs. This Series offers the right design for customers who require inline applications. They can simplify the clamping system between the motor shaft and the gears, and the output torque will be reduced to the standard level so that the speed ratio is reduced. If you don’t have enough budget but still require the precision and good performance of the speed reducers, then these Series of planetary gearboxes are what you find.

For standard planetary gearbox is designed with single-stage with the reduction ratio i = 3,4,5,6,7,8,9,10. We also provides customers with economic planetary gearboxes with two-stage and three-stage design with reduction ratio i = 12, 15, 16, 20, 25, 28, 30, 35, 40, 50, 70, 80, 100 and ratio i =60, 64, 72, 80, 90, 100, 120, 144, 150, 160, 180, 200, 240, 258, 288, 320, 384, 512, 600, 800, 1000 separately.

Output is for holes. Besides, there are three kinds of output shaft keyway: S1. Solid output shaft without keyway; S2. Standard type with a key and keyway. S3. Typically, we offer planetary reducers with an S2 common output shaft produced with a key and keyway. If you have a special requirement for the output shaft keyway, please inform us in advance.

Feature of PLF Economic Planetary Gearboxes

● High rigidity & torque
The use of integral ball bearings dramatically improves the rigidity and torque.
● Methods of flange and connector
It can be installed on any motor in the world.
● No grease leakage
Grease with high viscosity, which is not easy to separate, effectively prevents grease leakage.
● Convenient maintenance
There is no need to replace the grease during the product life period , and the installation is more convenient.
● Mounted in any position
You don’t worry about how to install the gearboxes thanks to its freely
● High efficiency
97% for 1-stage planetary gearboxes and 95% for 2-stages gearboxes

Application of PLF Economic Planetary Gearboxes

PLF inline gearbinlinere an economical alternative to the high precision planetary gearboxes, which are widely used in the fields of machine tools, textile, printers, packaging machinery, rubber machinery, production lines, cutting machine, mechanical arm-gantry, aluminum doors and windows equipment, sealing machines, testing machine, etc.

How to Select a Suitable Planetary Gearbox

Before selecting the speed reducer gearboxes, please confirm the speed ratio you need. And then multiply the nominated torque of the servo motor by the speed ratio to get a value. This value should be less than our speed reducer’s nominated output torque, which can be found in the attached parameter table. At the same time, you need to consider other overload conditions of the driving motor and select the maximum operating torque. Of course, this torque should not exceed two times the gearbox nominated torque. Once determined, you can choose the most miniature gearbox to achieve maximum savings. You can send us servo motor dimension drawings for us to make model selections for you or inform us about the specific servo motor model.
