	PNEUMABLOC® ELASTIC COUPLINGS	TECHNICAL DATA SHEET 84001 - 1/2 - 08/97
	General Characteristics	U4UUI - 1/2 - 00/9 1

Applications :

The PNEUMABLOC® couplings are used to solve :

Angular misalignment 4° max

Radial misalignment 3 mm max

Axial displacement 8 mm max

Dampens vibrations

General characteristics

• The flexible élément can be changed without disturbing the flanges

• The standard flexible part is made of natural rubber-» Use temperature range : - 42 °C to + 82 °C

• Instead of the standard element, a neoprene element can be supplied-» Use temperature range : - 40 °C to + 100 °C

• Upto size 120, the mechanical parts are made of steel coating with zinc and bichromate

• From size 140, the mechanical parts are made of FGL 250 cast iron painted black

• PV type : VECOBLOC® removal bush - PP type : prebored bush - PVP type : combination possibility of PP and PV type

Apparatus selection :

• Calculation of the power at 100 rpm (under 100 rpm, the determination is based on the nominal torque)

• Calculation of the service factor using the table below_

Internal combustion engines - 1 to 3 cylinders - unevenness factor : 1/80 to 1/100 Internal combustion engines - 4 to 6 cylinders - unevenness factor : 1/100 to 1/200 Electric motor - Steam turbine - Water turbine

• Apparatus selection taking account of the technical characteristics (see table below)

• Example : Coupling between a diesel engine 4 cyl. 45 kW 1500 rpm (0_shaft60) and a centrifugal fan (0_shaft55)

1) power at 100 rpm : 45 x 100 / 1500 = 3 kW

2) service factor : 1,5

3) selection of a size 90 (transferable power for a 1,5 service factor : 3,38 kW - max. speed : 2800 rpm - max. bore : 065 for PV type

Technical characteristics : ⁰⁷⁰ ^for ^PP ^type)
