More technical details of Samiflex elastic inserts Custom compounded polyurethane inserts provide elasticity and resistance to high torque, shear and shock loads. Elastic insert is highly resistant to humidity, oils, corrosion and chemicals retains performance characteristics at temperatures from -40 to 80 degrees C° (140 degrees C° Ref. HT). No lubrication or service is required. SAMIFLEX couplings had run 70,000 hours and more with no signs of wear.
Operation is completely silent at all speeds and loads. Initial cost is low, and maintenance and downtime are minimal.
No maintenace or lubricatione is nessassary.
After hubs (1) and (2) and holding ring (4) are installed on shafts, the teeth are them aligned parallel to each other, but not touching (fig 1).
Once installed, the hubs never need to be moved again.
The elastic insert (3) can then be installed in the slots formed by the parallel teeth.
When the insert is in position, slide holding ring (4) onto the polyurethane insert starting, centrifugal force will expand the elastic insert to fix it tightly to the inside of the steel ring ( fig 2 ).
As an extra safety it is possible to lock the ring with two locking screws (fig 3).
The elastic insert can be removed quickly and disconnect the dive side and the driven side easily for ex. test runs.
Calculation for Standard Type A
Information needed too make the size calculation
– kW on the drive side
– Speed (r.p.m.) on the drive side
– Shaft diameter on the drive side
Step 1: Kw x 9550 / Speed (rpm) = ”result” are Nom. Mom in Nm.
Step 2: Make the choice of size according to the “result” Nom. Mom. in the table (catalogue)
Step 3: Make a final check if the size can handle your shaft diameter in the table (catalogue)
Example (Electric motor drives a centrifugal pump)
55 x 9550 = 350Nm.
1500 = 350Nm.
1500
Electric Motor – 55Kw
Speed (r.p.m) – 1500
Shaft dia. Motor – Ø65 mm
Shaft dia. Pump – Ø42 mm
Calculated size: Samiflex A4
Nominal tourqe: 460 Nm
Max shaft dia. Ø65 mm
Calculation for Spacer Type CS
Information needed too make the size calculation
– kW on the drive side
– Speed (r.p.m.) on the drive side
– Shaft diameter on the drive side
– Avstånd mellan axeltappar (DBSE)
Step 1: Kw x 9550 / Speed (rpm) = ”result” are Nom. Mom in Nm.
Step 2: Make the choice of size according to the “result” Nom. Mom. in the table (catalogue)
Step 3: Make a final check if the size can handle your shaft diameter in the table (catalogue)
Step 4: Spacer length (Distance between shaft are the same as the space length, ex. 140 mm)
Example (Electric motor drives a centrifugal pump)
55 x 9550 = 350Nm.
1500 = 350Nm.
1500
Electric Motor – 55Kw
Speed (r.p.m) – 1500
Shaft dia. Motor – Ø65 mm
Shaft dia. Pump – Ø42 mm
Axelavstånd (DBSE) – 140 mm.
Calculated size: Samiflex A4cs / 140
Nominal tourqe: 460 Nm
Max shaft dia d1 (pump side) Ø42 mm.
Max shaft dia d2 (motor side) Ø65 mm.
