ESCOGEAR F Series Couplings
The ESCOGEAR F series couplings are all-metal torsionally rigid ESCOGEAR gear couplings with a two-piece body. The couplings enable the transmission of the highest torques with small installation dimensions.
Couplings Description
The ESCOGEAR F series 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 special Multicrown gear shape allows only a small backlash and allows smooth running over the entire speed and torque range. Grease lubrication ensures low maintenance and at the same time allows relatively large shaft misalignment.
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° (2 × 0.75°) in total. The axial misalignment capacity is limited by the gear teeth length in the sleeve and can be varied (optionally).
The couplings are manufactured for horizontal and vertical applications.
Couplings Construction
- Two-piece outer flanged sleeve with internal Multicrown teeth
- Left hub with external teeth
- Right hub with external teeth
- Special high strength bolts
- Seal in outer sleeve (o-rings)
Couplings Fields of Use
ESCOGEAR F Series shaft couplings are designed to transmit the highest torques in all industries.
They are used mainly in the drives of conveyor systems, rolling mills, mixers, cranes and other demanding drives in steel mills, in the paper, chemical and rubber industries.
The unique modular system offers maximum flexibility in assembling various configurations, including suitable accessories such as brake discs or drums, etc. The couplings are available in various sizes and designs.
Couplings Material
Gear couplings are generally made from carbon steel Ck45 (AISI 1040). For higher torque capacities, within the same coupling dimensions, a higher alloy steel like 42CrMo4QT can be used (optionally).
Couplings Advantages
- High torque capacity and important angular misalignment allowing the coupling to operate under combined load, speed and misalignment conditions
- Easy coupling selection
- High bore capacity
- Light weight
- The highest manufacturing quality and long coupling life guaranteed
- A Multicrown gear shape
- Perfect homokinetic torque transmission
- Reduced backlash
- Perfect gear top centering
- Zinc coated body fitted flange connection bolts avoiding fretting corrosion in the flange bores
- An excellent protection of components
