In this field, the equipment often rotates quickly, up to 40000rpm sometimes. Thus, it has very particular requirements for the rotation performance of coupling, with balance level generally of G1.0 above. Particularly, in the steam turbine, the coupling shall not only have excellent balance, but also transmit large torque, and have complicated lubrication conditions. Learning from the experience of advanced products, the steam turbine coupling developed by Rokee makes a breakthrough and fully takes lubrication and operation accuracy into account. With special design, the drum teeth part is carburized and ground and lubricated with thin oil jet, which was proved to be very successful through years of practices.

Multiple varieties of flexible diaphragm couplings designed and manufactured by us have been applied on air blow and ventilation devices. It adopts multiple advanced technologies, such as aided design of taper bolt compaction of PEM, etc., and also particularly focuses on balance control. Now, it is widely used by major host companies.

Practices have proved that our high-quality products can substitute imported products completely, saving large costs for owners, filling up the blank of domestic market and breaking the monopoly position of foreign manufacturers.
