ESCOGEAR C and C-M Series Couplings

The ESCOGEAR C and C-M series couplings are all-metal torsionally rigid ESCOGEAR gear couplings in a compact design with a one-piece body. The couplings enable the transmission of the highest torques with small installation dimensions.

Couplings Description

The ESCOGEAR C and C-M series couplings are torsionally rigid grease filled couplings consisting of two hubs with external Multicrown - 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 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 - for C-M series only).

The ESCOGEAR C and C-M series couplings are significantly lighter than the ESCOGEAR F series couplings. This compact design is ideal for use in applications where space and weight savings are important. There are two versions available - CST for max. finished bore up to 110 mm and CST-M configuration for larger bores. The couplings are able to compensate for radial, angular and axial misalignments.

The couplings are manufactured for horizontal and vertical applications.

  2. Left hub with external teeth
  3. Right hub with external teeth
  4. O-ring

Couplings Fields of Use

ESCOGEAR C and C-M 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 modular system offers maximum flexibility in assembling various configurations. 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 as 42CrMo4QT can be used (optionally).

Couplings Advantages

  • High torque capacity and significant angular misalignment allowing the coupling to operate under combined load, speed and misalignment conditions
  • Easy coupling selection
  • High bore capacity
  • Light weight
  • Long guaranteed coupling life
  • Multicrown tooth form
  • Perfect homokinetic torque transmission
  • Less backlash compared with conventional or circular tooth forms
  • Perfect gear top centering
  • Excellent corrosion protection of components
