PLANETARY GEARSET

Planetary gearbox also known as epicyclical gear is a set of two gear mounted on each other to revolve centre of one gear around the centre of other. The planetary gearbox mechanism works as our solar system. Centre gear which is also called sun gear rotates which drives the planet gears. The load from the sun gear is applied to multiple planetary parts, which can either be employed to run an outer ring or a spindle or shaft. Due to number of planetary gears the planetary gearbox can produce lot of torque resulting those planetary gears divide the load. The planetary gearbox also provides stability due to an even distribution of load and increased rotational stiffness. SMD planetary gear trains consist of spur gears.  

The main advantage of using a planetary gearbox in combination with a servo motor is that the torque is separated over 3 gears (the planet parts), and therefore – at the same dimensions – the torque is almost 3 times more than a typical gearbox.              

Planetary gearbox is used in applications where weight and space are issues and large number of reduction ratio and torque is needed. These type of gearbox is needed in the applications like construction equipment, defence equipment where large number of torque is needed to drive the wheels. The other applications like jewellery making machines, robotics industry, automation industry also use planetary gearbox. Planetary gear units are widely use because their principal advantage is they allow both the input and output axes to be concentric, thus providing a very compact gear arrangement.    

SMD gearbox is a well known gearbox solution provider in gearbox industry. We have a long list of satisfied customers. Planetary, Hollow rotary, Right angle, Harmonic and Cycloidal these are the servo gearboxes in which SMD gearbox deals. SMD provides integrated solution to its customer. We can avail above type of gearboxes in different wide range of dimensions and reduction ratios. We also provide integrated solution with combination of one or more type of gears. SMD has expert technocrats who helps you thoughout your automation proess to meet expected result.

SMD introduced two series in Planetary Gearbox that is with flange(SNDU Series) and with shaft(SNP Series). Both comes in wide range of reduction ratios and dimensions. SMD also introduced right angle gearbox which is again also one of the type of planetary gear with 90 degree output angle. It is very useful in applications where the demensions are very low. SMD also provides you an integrated solution by using more than its products to achive your automation process successfully.
