Nylon Sleeve Gear Coupling/curved-tooth gear coupling

1.    Compensation of axial, radial and angular misalignment of shafts through double cardanic action

2.     It is very sample and easy to assemble .

3.     High electrical insulating property.

4.     The coupling sleeve is made of high performance polyamide, so it could be self lubricated, anti corrosion and water proof.

5.     No maintenance needed, and it is applicable for hydraulic transmission and engineering machinery

6.     The standard working temperature for this RB series coupling is -25℃ to 80℃.

7.     Working under the condition of mineral acid, ethanoic acid, cresol etc..., special material made coupling sleeve are available.

Technical explanation

The RB series coupling is a flexible coupling whose typical features are two congruent hubs with crowned teeth which transmit torque by meshing with the internal toothing of a housing component. The coupling sleeve with axially parallel involute gearing is centered at the tooth flanks of the coupling hub.

The coupling design meets the requirement to compensate radial, angular and axial shaft displacement in order to release the neighboring shaft bearings from non-controlled, additional loads.

Even with maximum permissible edge contact of the teeth is excluded and there would be no periodic variation of the angular velocity. The high internal cushioning properties of the classic material used for the coupling sleeve reduce the effect of shock loading.

RB series coupling are suitable both for for horizontal and vertical shaft connection, for reversing and intermittent service. The steel/plastic combination also has the vantage that no lubrication by oil or grease is required; the coupling, therefore does not need any maintenance.

Maximum service reliability is guaranteed at temperature in the range from -25℃ to 80℃. It is necessary to use a coupling sleeve in heat stabilized polyamide for temperature up to +140℃.
