Samiflex - elastic coupling

Standard coupling
Type A

Manufactured according DIN 740. 

Sizes from A0 to A12 and up to 300 mm in shaft diameter.

Standard coupling
Type CS

A compact version of the standard coupling with material covering the shaft. Sizes from A1cs to A8cs. Maximum 120 mm shaft diameter. 

Bigger sizes on request.

Spacer coupling
Type CS

A model for longer shaft distances. Sizes from A1cs to A9cs and up to 500 mm in shaft distances. 

All standard spacer lengths available.

Standard coupling
Typ A för Taper-Lock

Available for both exterior and interior mounting of the Taper bushing. Sizes from A1 to A7 and shaft diameters up to 100 mm.

Spacer coupling
Type DL

Double spacer coupling for longer shaft distances up to 500 mm.

Brake drum coupling
Type PF

Available in sizes from A4 PF-250 to A10 PF-710.

Flange mounted coupling
Type EB

Available in sizes from A2EB to A8EB and ready for SAE standard.

Brake disc coupling
Type DF

Availeble in sixes from A4 DF-315 to A10 DF-710.

A new DO - Drop Out model is available which allows you to change the brake disk without moving the hubs.

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.

 

Mounting

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

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.
