※ The metal of UCR-125, UCR-155, and UCR-200 is ordinary cold-rolled steel (SPCE).

Shaft Installation (In the case of keyway tightening)

Insert the two hubs onto the respective shafts.
Fix the two cross pins to the hubs using the arm clamping bolts, securing two bolts to each hub. Use a torque wrench to tighten the bolts according to the tightening torque listed in the table (page 16). Also, apply an anti-seize compound to the bolts.
For the shaft and keyway tightening, set screws should be installed in the fixed keyway or at two points that are 90° apart from the key’s top, securing with two screws.

Sakai UA-C Series Precision Shaft Coupling

kvt part2 — Sun, 16 Aug 2020 07:51:23 +0000

Manufacturer: Sakai Manufacturing Co., Ltd.
Model: UA-C Series

Features

The high-rigidity body and double bolt clamp ensure suitability for high-precision, high-response control.
Cross-shaped pins on the center block and metal in the hub arm absorb eccentricity and angular misalignment with minimal clearance, ensuring accurate rotation.
The structure allows free sliding and rotation of pins and metal, reducing support reaction force and increasing torsional rigidity, improving control responsiveness in servo and pulse motor applications.
The compensation type’s damping properties and high torsional rigidity reduce vibration transmission, offering effective vibration control.
Minimal support reaction force makes installation easy.

LCD-125T7 and LCD-155T7 are semi-standard products (delivery time confirmed).
The allowable radial direction displacement represents the case the eccentricity and tilt angle are zero.
The eccentricity and tilt angle act simultaneously. The system restricts the allowable tilt angle. Insert the shaft up to the marking line J correctly.
The moment of inertia and mass represent the maximum shaft hole diameter.
The recommended shaft tolerance is h6, corresponding to a tolerance of 0 to 0.010 for a shaft diameter of 35 mm.
The maximum rotational speed does not account for dynamic balance.

Sakai LAD-C Series Precision Spring Coupling

kvt part2 — Sun, 16 Aug 2020 01:10:05 +0000

Manufacturer: Sakai Manufacturing Co., Ltd.
Model: LAD-C Series

Features

A unique laminated leaf spring with excellent precision and rigidity has used as the flexure material. Two sets of laminated leaf springs attached to the hub with bolts and high flexibility create a non-backlash structure, achieving high precision and high torque rotation transmission.
Two sets of laminated leaf springs sandwiched between spacers absorb eccentricity, angular misalignment, and axial displacement. This precision shaft coupling combines high versatility with high flexibility, easy centering, and high precision rotation transmission.

The moment of inertia and mass are calculated, the shaft hole diameter is at its maximum.
Be sure to insert the mounting shaft up to the J dimension.
The recommended shaft tolerance is h6. (Shaft diameter 35mm, tolerances of 0 to +0.010 are supported.)
The allowable axial displacement represents the case the deviation angle is zero.
The maximum rotation speed does not take dynamic balance into consideration.
The 🟤 mark indicates a non-standard hole diameter (delivery confirmation hole diameter).
