Introduces the Ceiling-mount and inverse type SCARA robots YK-XGS Wall-mount and inverse type SCARA robots As the ceiling installation or the wall installation is used, the robot installation space that could not be used conventionally can be utilized efficiently. Feature Hanging type is renewed. Completely beltless structure and high rigidity As the conventional hanging type is changed to the wall mount type, the flexibility of the system design is improved. The production equipment can be downsized. Additionally, as an inverse type that allows upward operation is also added to the product lineup, the flexibility of the working direction is widened. Furthermore, use of a completely beltless structure achieves a maximum payload of 20 kg and a R-axis tolerable moment of inertia of 1 kgm2 * that are the top in the class. A large hand can also be installed. So, this robot is suitable for heavy load work. Internal structure achieving the high-rigidity and high-accuracy. Completely beltless structure A totally beltless structure was achieved by using a ZR axis direct coupling structure. This direct drive structure drastically reduces wasted motion. It also maintains high accuracy over a long period of time. It ensure maintenance-free usage for extended periods with no worries about belt breakage, stretching or deterioration with age (feature applies to all XG series models and the YK180X/YK220X). The standard cycle time is fast of course but the YAMAHA design also stresses tact time in the actual usage region. A drastic improvement in maximum speed was made by changing the gear ratio and maximum motor rpm
