Briefly describe the failure protection measures of the diaphragm coupling

Diaphragm coupling is suitable for corrosive media: Diaphragm coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the connected two shafts. It is a high-performance flexible coupling with metal elastic elements and does not require lubrication. It has a compact structure, long service life, no rotation gap, and is not affected by temperature and oil pollution.Compared with the gear coupling, the diaphragm coupling has no relative sliding, no need for smoothness, sealing, no noise, no maintenance at all, easy to manufacture, and can partially replace the gear coupling.Diaphragm couplings are already common in countries with prosperous industries around the world, and regulations for the machinery industry have been formulated in our country.When our staff are answering questions from users, some users cannot accurately know the type and model of the product they need, which is not good for the user's selection, so we have collected most of the couplings in my country. Standard drawings and detailed dimensions, the establishment of a coupling dimension lookup table, can bring convenience to users.

The diaphragm coupling has the brightness close to the mirror surface, and the touch is tough and cold. It is a more avant-garde decorative material and conforms to the cool aesthetic of the metal age.With the characteristics of acid and alkali resistance, it is suitable for high temperature, high speed, and corrosive medium shafting transmission. The stainless steel diaphragm coupling has excellent corrosion resistance, formability, compatibility and wide temperature The range of features such as strength and toughness makes it widely used in heavy industry, light industry, daily necessities industry, and building decoration industries.

XNUMX. What regulations should the diaphragm coupling comply with?

(1) The main parameter of the coupling is nominal torque 7; the unit is Nm, and its parameter value should meet the regulations.

(2) The nominal torque sequence number or size parameter of the coupling is the specification code of the coupling.

(3) The group code, variety code, and structure type code of the coupling shall be coded by one Chinese pinyin letter of one character in its name.If there are repetitions, choose two letters, or one or two Chinese pinyin letters of two or three characters in the name, or choose one or two Chinese pinyin letters with characteristic characters in the name, so as to be in the same group and variety The principle is not to overlap with the structure type.

(4) The coupling model is composed of group code, variety code, and structure type code.

XNUMX. Briefly describe the failure protection measures of the diaphragm coupling

1. Appropriate stabilization and protection measures must be taken at various sites that may be caused by operating diaphragm couplings and equipment accidents;

2. During work and operation, check whether the diaphragm coupling is abnormal, and repair it if any abnormality occurs;

3. Before installation, the end faces of the two shafts should be cleaned, and the diaphragm coupling should be checked for the coordination of the key grooves on the end faces;

4. Long-term overload use and operation accidents should be avoided;

5. In order to prevent the fretting of the diaphragm during high-speed operation, causing microcracks and damage to the bolt holes of the diaphragm, solid lubricants such as molybdenum disulfide can be applied between the diaphragms or the surface of the diaphragm can be coated with anti-friction Layer processing

6. After the diaphragm coupling is installed, run a shift normally. All screws must be checked. If they are found to be loose, they must be tightened. Repeat this for several shifts to ensure that they will not loosen;

The diaphragm coupling is composed of at least one diaphragm and two shaft sleeves.The diaphragm is fastened to the shaft sleeve with a pin and generally does not loosen or cause backlash between the diaphragm and the shaft sleeve.Some manufacturers provide two diaphragms, and some provide three diaphragms, with one or two rigid elements in the middle, and the two sides are connected to the shaft sleeve.Diaphragm couplings and tire couplings can be used not only in dyeing equipment, but also in textile equipment such as flat washing machines and cloth washing machines.The diaphragm coupling consists of two halves of the coupling and the stainless steel coupling diaphragm in the middle. The principle is to adjust the misalignment of the two couplings through the three-dimensional deformation of the stainless steel diaphragm. Because the coupling is connected, It does not need lubrication, oil stains, and has good impact. It is also one of the couplings of dyeing machinery.Diaphragm couplings are commonly used in shaft transmissions of various mechanical devices, including textile machinery.The dye liquor for textile circulates in the circulation system of the dyeing machine, and the circulation pump is driven by the motor through the coupling.
