LOWER STRESSES. STRESS PATTERN AND. The ESCO MULTICROWN tooth form is a curve with CONTACT AREA COMPARISONS. constantly changing radii of curvature. The tooth contact area under misaligned conditions has a much larger radius of curvature than conventional crowning. The contact area therefore is larger thus reducing the surface stresses. CONSTANT VELOCITY POWER TRANSMISSION.

2 ESCO generates the ESCO MULTICROWN, tooth in such a way CONVENTIONAL ESCO MULTICROWN. that the necessary characteristics for homocinetic conjugate Variable pressure tooth action are perfectly achieved. Constant pressure Variable force Variable force LESS BACKLASH. The ESCO MULTICROWN tooth design requires less backlash for a given angle of misalignment than the conventional crowning, thus reducing shocks in reversing application.

Select the size of escogear coupling that will accommodate the largest shaft diameter. 9550 x P x Fu x F. B. Make sure this coupling has the required torque capacity according to following formula: n torque in Nm =.

4 P = power in kW; n = speed in rpm; Fu = service factor according to tabulation 1. F = 2 in case of use in potentionally explosive atmospheres , European Directive 94/9/EC. In normal atmospheres, F = 1. The coupling selected per (A) must have an equal or greater torque capacity than the result of the formula (B). If not select a larger size coupling . Check if application peak torque does not exceed tabulated peak torque Tp indicated planographs B410 to B423. Check also max. allowable misalignment using the graph of tabulation 2. C. Check if shaft/hub connection will transmit the torque. If necessary, select a longer hub. D. Read carefully assembly and maintenance instructions IM/B400. DRIVER MACHINE.

Maximum torque, maximum speed and maximum misalignment may not occur simultaneously. Graph must be used as follows: 1. Calculate Tn and Tp and select coupling size as usual. Tn = nominal torque; Tp = peak torque 2.

7 Calculate Tn/TnRef and n/nRef and plot the resulting point in the graph. 3. If the resulting point is located in the white area, a standard coupling may be used as far as maximum misalignment doesn't exceed the maximum misalignment indicated in the graph. 4. If the resulting point is located in the shaded area, refer to ESCO COUPLINGS. 5. In case of use in potentionally explosive atmospheres , proceed the same way but using Tn Ref for the calculation. Max misalignement may not exceed 0,5 per gear mesh.
