PRODUCTION RANGE
1. UNIVERSAL SHAFTS
2. GEAR SPINDLES
3. GEAR COUPLINGS
The universal shaft enables motion transmission between driving and driven shafts, with wide working angles. The major characteristic of a universal shaft is having a transmission ratio instantly varying, when misalignment is different from zero. The transmission ratio average value however keeps uniform; to annul such variability, the connection is made by two universal joints, equalizing the angular velocity. Motion transmission is realized by a component connecting input and output shaft ends. This component is called journal cross. Generally speaking, the universal shaft operation can be distinguished into 5 single peculiarities:
1. Torque and speed
2. Possibility of changing the distance between input and output
3. Possibility of changing the angle between input and output
4. Stress for vibration
5. Torsional strength

COMPANION FLANGES
We can manufacture any type of companion flange, following your
requirements. Generally speaking, these sleeves are grouped into 2
families, following their geometric shape:
a. CYLINDRICAL COMPANION FLANGES
b. FLANGED COMPANION FLANGES
Or, following the type of connection between its flange and the universal
shaft one, they are divided into 5 categories:
1. FLANGE WITH NO KEYWAY
2. FLANGE WITH KEYWAY
3. FLANGE WITH HIRTH SERRATION (as the picture on the right)
4. FLANGE WITH DOG TEETH
5. FLANGE WITH NO KEYWAY WITH PINS ACCORDING TO DIN 15452 STANDARDS
