Features

• New coupling with universal joint and allowable end play function.
• Low cost is achieved with a simple structure consisting of three elements: an outer hub, an inner hub, and a sphere.
• Sturdy structure that can withstand shock torque in an emergency.
• Left and right hole diameters are freely selectable in the range of φ6 to φ12, including combinations.
• Use of special grease with high viscosity prevents scattering even at 1500rpm.
• For pumps, medical equipment, electric chairs, agricultural machinery, transportation, construction machinery, robots, etc.
• [Ball Coupling]
• Ball couplings are rotation-transmitting elements that combine the functions of universal joints and splines.
• The ball coupling consisting of three elements, an inner hub, an outer hub and a ball, has been patented for its functional structure.
• There are no size restrictions, so there are many possibilities from micro to large couplings.
• Compared to the size of the outer shape, the transmission torque, especially the damage torque, is large, so the device can be miniaturized.
• Since there are no basic restrictions on the material of the hub and ball, it can be used in water, oil, high temperature and low temperature vacuum.
• Couplings of declination angle and eccentricity (spline) amount can be designed to suit the required use in actual production.
• We can expect future developments in such fields as micro-robots, automatic machines, packaging machines, and large industrial machines.
• High speed and high rigidity servo support can also be considered.
