ESCO COUPLING

The Escogear coupling is a torsionally rigid grease filled coupling consisting of two hubs with external multicrown - and two flanged sleeves with straight internal teeth.  The flanged sleeves are bolted together with high strength corrosion protected fitted bolts and nuts. The sleeve is at the opposite side of the flange executed with an endcap (internal for small and screwed for big size couplings) in which the o-ring is located for sealing purposes. The Escogear coupling has been designed to transmit the torque between these two flanges through friction avoiding fretting corrosion between these faces.

Gear couplings are lubricated type couplings with the highest torque capacity.  The Escogear FTRN series couplings basically consist of two hubs with external teeth connected by means of two internally geared sleeves or so called flanges.

The Escogear C & C...M series couplings are torsionally rigid grease filled couplings consisting of two hubs with external crowned - and one single sleeve with two pairs of straight internal teeth on each sleeve end, a so-called continuous sleeve. Both sleeve ends are sealed. These are the most compact gear coupling designs.The teeth of hub and sleeve are continuously in contact with each other and have been designed with the necessary backlash to accommodate angular-, parallel- and axial misalignment within their misalignment capacity. The angular and parallel misalignment capacity is determined by the gear tooth design and is for the standard Escogear max. 1.5° degrees (2 x 0.75°) in total. The axial misalignment capacity is limited by the gear teeth length in the sleeve and can be varied (optionally - for C...M series only).Gear couplings are generally made from carbon steel Ck45 (AISI 1040). For higher torque capacities, within the same coupling dimensions, a higher alloy steel as 42CrMo4QT can be used (optionally).The Escogear C & C...M series are substantially lighter in weight than the Escogear F-series. These compact designs make the Escogear C & C...M series ideal for use in applications where space is limited and weight is important. Two versions are available. The CST for bores up to 110 mm and the CST...M configuration for larger bores.

The Escogear High-Speed series couplings are lubricated type couplings, also called high-performance gear couplings. Used in high-power/ high-speed applications, they incorporate specific and high-precision gear geometrics as well as a dedicated cooling / lubrication system based on grease or oil to allow for long continuous running periods without maintenance
