Most compact solution

<-> Flanged Gear type : 17% smaller O.D. <-> Disc type : 30% smaller O.D. <-> Elastic type : 52% smaller O.D. This compactness makes the escogear C series ideal for use in applications where space is limited and weight important

Outside Diameter (mm)

Thanks to the high torque capacity and the continuous sleeve design, the escogear C and C... M couplings are the most compact answer to any transmission applications. In comparison to other types of couplings and for a given torque they have a substantly lower weight and reduced outside diameter:

HOW TO SELECT THE RIGHT COUPLING SIZE A. Select the size of ESCOGEAR coupling that will accommodate the largest shaft diameter. B. Make sure this coupling has the required torque capacity according to following formula:

9550 x P x Fu x F

torque in Nm =

n 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 A310 to B317. Check also max. allowable misalignment using the graph of tabulations 2 and 3. C. Check if shaft/hub connection will transmit the torque. If necessary, select a longer hub. D. Read carefully assembly and maintenance instructions IM/A300 and IM/B300. DRIVER MACHINE

HOW TO USE THE GRAPH ? 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. 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 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.

For key according to ISO R 773. Gear maximum continuous transmissible torque for the tabulated misalignment. The effective transmissible torque depends on the bore and shaft/hub connection. Higher speed on special request. For grease withstanding centrifugal acceleration of 1.000g. See installation and maintenance manual IM. For grease withstanding centrifugal acceleration of 2.000g. See installation and maintenance manual IM. Depends on S. For long operation in disconnected position contact us. For solid bore. Depends on S. For solid bore and S minimum. Per 100 mm spacer length. Depends on L and R. For pilot bored hubs. Depends on S. For pilot bored hubs and S minimum. Per 100 mm spacer length. Depends on L and R. See installation and maintenance manual IM. Depends on S. Values given for S maximum. On request. For larger S contact us. Values for S minimum. S maximum depends on torque and speed. G must remain constant during operation. Needed to control the alignment and inspect the gears.
