The present invention relates to a high-power downsizing RC decelerator and a method of manufacturing the same, and more particularly, to a high-output downsizing RC decelerator with improved output torque while reducing the height of the RC decelerator and a method of manufacturing the same.

In general, the RC reducer has a constant height due to its structure and manufacturing characteristics.

Therefore, when applied to a conveyor line or the like, the height of the conveyor line installed due to the height of the RC decelerator is increased.

Accordingly, in order to adjust the height of the finally installed conveyor line to a suitable height for the operator, it is necessary to form a groove for installing an RC decelerator on the floor surface and then install an RC decelerator in the groove.

However, this not only deteriorates the maintenance of the RC decelerator, but also requires a separate groove forming work for installing the RC decelerator when the work line is installed, leading to an increase in installation cost.

To solve this problem, as shown in FIG. 1, the height h problem is solved through the construction of the first cam follower bearing and the second cam follower bearing.

However, in order to lower the height, the configuration of a separate bearing for raising the output torque is omitted except for the configuration of power transmission and output transmission through the first cam follower bearing and the second cam follower bearing. This is because characteristics of the cam follower bearing, The output torque of the RC decelerator shown in Fig.

On the other hand, the RC decelerator is disclosed in Japanese Patent Registration No. 10-1384949.
