One of the most critical mechanical structures of industrial robots is the RV gear reducer.

 

 

Mechanical principle of RV gear reducer

 

In 1926, the German Lorenz Brown proposed a planetary gear mechanism with a small tooth difference. It uses the epicycloid as the tooth profile curve. This is the earliest pinion planetary transmission due to the two meshing. One of the gears is in the form of a pin wheel, which is also referred to as a cycloidal pinion planetary gear.


RV transmission is a brand - new transmission method. It is developed on the basis of the traditional oscillating planetary transmission. It not only overcomes the shortcomings of the general swaying transmission, but also has a small size, light weight, large transmission ratio range and long service life. A series of advantages such as stable accuracy, high efficiency and smooth transmission.

 

 

Take the RV-E gear reducer as an example

 

1. First reduction unit - spur gear reduction mechanism


The rotation of the input shaft is transmitted from the input gear to the spur gear, and is decelerated by the gear ratio. This is the first speed reduction section.


2. Second speed reduction unit - differential gear speed reduction mechanism


The spur gear is connected to the crankshaft and becomes the input of the second reduction unit. In the eccentric portion of the crankshaft, the RV gear is mounted by a rolling bearing. In addition, the needle teeth on the inner side of the casing are only one more than the number of RV gears, and are arranged at the same pitch.


If the fixed housing rotates the spur gear, the RV gear also performs eccentric motion due to the eccentric motion of the crank shaft. At this time, if the crankshaft rotates one revolution, the RV gear will rotate one tooth in the opposite direction to the crankshaft. This rotation is output to the shaft of the second reduction unit. When the shaft is fixed, the casing side becomes the output side.
