Tooth center distance

The production process of the curved tooth couplings was invented by The nominal size of the coupling is no longer synonymouswith the maximum permissible hub bore.Օ Larger hub bore capacities allow a more favorable couplingsize selection. Higher permissible angular misalignment capacity providesadded safety in the event of shaft offset. Օ Precise and subtle size determination due to the applicationof service factors. Re-structured product range ensures simplified couplingselection. Albert Tacke more than 60 years ago andwas already patented in 1939. The worldwide use of the curved tooth...

The couplings of the SB series can either be lubricated withoil or with grease. The advantage of oil lubrication is that the lubricant can be replaced in a quicker and easier manner. On top of this, the SB coupling types have a larger space for the lubricant. Lubrication is ensured even in case of a damaged sealing. This equally applies to oil and grease lubrication. Irregardless of the quantity, special designs can be suppliedin any size. The distinction is made between modified stan- dard types and custom-made designs. Modified coupling models are mainly composed of elements from the...

The basic type of the HYGUARD > HYGUARD > ή is a hydraulicsafety element to protectmachinery against overloads. In combination with curved tooth couplings, HYGUARD safety coupling isthe B-design. Due to the com- pact dimensions, this coupling can be combined with the mostdiverse drive elements withoutaffecting their torque transmis- sion capacity. The HYGUARD > works like a safety coupling with torque limitation. Therelease torque is adjustable andremains constant throughout the entire operation time. > ή couplingsleeve is equally suitable for clamping fixed as well as rotating elements....

Two components are of essen-tial importance for safe release: the shear ring and the shear tube. The shear ring and theshaft are rigidly connected,whereas the shear tube is accommodated in the movable part. If the operation torque exceeds the pre-determinedvalue, the safety element startsto slide on the profiled surface. This results in a relative move- ment between the shaft andthe hub, with the shear ring cutting off the shear tube. Thesystem is depressurized within milliseconds and the connec- tion is released.
