A few sets of diaphragm (stainless steel sheet) are bolted to the coupling of the two halves of the coupling, each of which is composed of several folds, and the diaphragm is divided into connecting rod and different shapes.Diaphragm coupling on the elastic deformation of the diaphragm to compensate for the two axes relative displacement, is a kind of high-performance metal flexible coupling components, no lubrication, structure is compact, high intensity, long service life, no rotating clearance, not influenced by temperature and oil pollution, has the characteristics of acid and alkali corrosion resistance, suitable for high temperature, high speed, working condition of a corrosive medium environment of shaft transmission.

Installation steps of diaphragm coupling:

1、Coupling at the scene of the installation, please carefully check each parts don't have a defect, which contains a set of coupling active half couplings, passive coupling half one, six continuous diaphragm set a pair of articulation, high strength bolt, nut, spring washers, a total of six.Half in active and passive half a league has not yet been installed for corresponding host shaft and is in place to look for is finished, please take good care of diaphragm group (do not throw, knock against, weight and maul), lest affect the precision of film slice and integrity;
2、Effectively clean the oil and paint of the inner hole of half coupling and flange.The main and passive parts are respectively heated by oil bath or induction heating (the temperature should not exceed 300 degrees, which should be controlled at 160 to 250).Before heating please make preparations for the assembly, check the shaft hole size, length, keyway width and depth of keyway if there is a dimension error, the host shaft head if there is a serious knock against or strain, in order to avoid in the process of heating the half yearly suits cannot effectively in place, thus affecting use even scrapped, or because the product does not reach the designated position, users can't pinpoint the last order spare parts installation and use;

3、The main and passive half coupling on the main engine will be used to find positive, rough and accurate steps to find the correct installation。

(1.)Preliminary estimate alignment: is the means to control the motor to the naked eye, the position of the fan in a horizontal distance and height difference before and after, and axial Angle preliminary into the position, in order to prepare for the next step is find;

(2。)Coarse alignment: the simplest way is to use, with a ruler or vernier caliper and calipers to control large end face of two and a half coupling is parallel to the relative, the relative spacing meets the technical requirements of the open file t value, generally open files actual value is greater than the theoretical value of 0。5 mm to 0。8 mm, between two and a half coupling Flange of the cylindrical, front and back, up and down four radial position deviation are consistent。

Note: please follow this installation instructions carefully before using, and do the following carefully. You will have a flexible coupling that is free of maintenance, long life, low fault and high reliability.
After-sales service commitment:

1、Service tenet: quick, decisive, accurate, thoughtful and thorough.
2、Service goal: service quality wins customer satisfaction.
3、Service efficiency: if the equipment fails during the warranty period or the warranty period, the supplier can reach the site within 24 hours after receiving the notice and start the repair.
4、Service principle: the product warranty for 12 months, during the warranty period the supplier will be free repair and replacement of damaged parts belong to the quality reason, warranty parts damaged, only accept cost, provide fittings by the buyer's equipment damage caused by human factors, the supplier repair or provide fittings are at the cost price.
