Additional information

Assembly

– Execution <STRONG>B</STRONG>: plain holes.<BR>- Execution <STRONG>K</STRONG>: holes with DIN 6885/1 keyway.

Example 1

Output to be transferred N = 5.5 kW<BR>R.p.m. n = 2300 min<SUP>-1</SUP><BR>Angle of inclination ß = 10°<BR>Correction coefficient k = 1<BR>Indicative output N' = Nominal output N<BR>Intersection point P is arrived at from 5.5 kW and 2300 min<SUP>-1</SUP> (which corresponds to a torque of 23 Nm).<BR>The next size up universal joint corresponding to point P is in the model with a diameter d1 = 28.

Example 2

Torque to be tranferred M = 23 Nm<BR>R.p.m. n =2300 min<SUP>-1</SUP><BR>Angle of inclination ß = 18°<BR>Correction coefficient k = 1.43<BR>Indicative torque M' = 1.43 x 23 Nm = 33 Nm<BR>Intersection point P1 is arrived at form 33 Nm and 2300 min<SUP>-1</SUP> (which is equivalent to an indicative output N' = 7.9 kW).<BR>The next size up universal joint corresponding to P1 is the model with a diameter d1 = 32.

Features and applications

DIN 808 W universal joints with needle bearing are known for their precision. They have minimal play and are long lasting. The r.p.m. of universal joints with needle bearing is higher than the level achieved by the joints with friction bearing, but still it is dependent on the type of application, load, duration of use and angular position. Ideal applications allow speeds up to 4000 r.p.m.<BR>If they are angled between 3° and 5° they can reach a considerably high degree of efficiency.<BR>Needle bearings have a permanent lubrication and thus do not require servicing.

Material

Hardened steel.

Special executions on request (For sufficient quantities)

– Execution <STRONG>V</STRONG>: square holes.

Standard executions available

– Execution <STRONG>EW</STRONG>: steel single body with needle bearing. <BR>- Execution <STRONG>DW</STRONG>: double body with needle bearing.

Technical data

The table shows the transferable output N and/or torques M of universal joints DIN 808, type EW (single needle bearing) in relation to the r.p.m. (n). The values are only applicable to a constant speed of rotation, constant load and an operating inclination angle of max 10°.<BR>For larger inclination angles ß a nominal output N' increased by the correction coefficient k and/or a nominal torque M' has to be selected (see example below).<BR>Conversion formulae:
