Innovative design and analysis of diaphragm coupling?

Diaphragm coupling is a commonly used accessory in couplings, and every motor is inseparable from this part in order to work normally.Although it is small, its importance is obvious.So, what is the innovative planning and analysis of diaphragm couplings?Let's take a look at it together

Diaphragm couplings are classified as rigid-flexible couplings. Diaphragm couplings are composed of internal gear rings with the same number of teeth and flange half couplings with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The center of the spherical surface is on the gear axis. The tooth side gap is larger than that of ordinary gears. The drum-shaped tooth coupling can Allowing a larger angular displacement (compared to a straight tooth coupling) can improve the touch condition of the tooth, improve the ability to transmit torque, and extend the service life.Touch along the width of the tooth when there is angular displacement.It has the ability to compensate for axis errors such as radial, axial and angular axis. It has the advantages of compact structure, small gyration radius, large load capacity, high transmission power, low noise and long repair period. It is especially suitable for low-speed and heavy-duty conditions, such as In metallurgy, mining, lifting and transportation industries, and also suitable for various machinery such as petroleum, chemical industry, general machinery and other machinery, the shaft transmission gear couplings have relative angular displacements of the two shafts during operation, and the tooth surface cycle of the outer and inner teeth The relative sliding movement in the axial direction will inevitably constitute tooth surface wear and power consumption. Therefore, the gear coupling needs to be operated under excellent and sealed conditions.Diaphragm couplings have small radial dimensions and large load capacity. They are often used in shafting transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting. transmission.

The characteristics of the drum gear coupling (compared with the straight gear coupling has the following characteristics): 1. The drum gear coupling has strong bearing capacity.Under the same outer diameter of the inner gear sleeve and the outer diameter of the coupling, the load-bearing capacity of the drum gear coupling can be evenly improved by 15-20% than that of the straight gear coupling. The angular displacement compensation is larger.When the radial displacement is equal to zero, the allowable angular displacement of the straight diaphragm coupling is 2o, and the allowable angular displacement of the diaphragm coupling is 1o1', an increase of 30%.Under the same modulus, number of teeth, and tooth width, the angular displacement of the diaphragm is larger than that of the straight tooth. 50. The drum-shaped tooth surface of the diaphragm coupling improves the touch conditions of the inner and outer teeth and avoids the angular displacement. Under the circumstance, the edge of the straight tooth is kneaded and the stress is concentrated, which together improves the conflict and wear of the tooth surface, reduces the noise, and the repair cycle is long. 3. The tooth end of the outer gear sleeve of the diaphragm coupling is in the shape of a horn, which makes the assembly and disassembly of the inner and outer gears very convenient. 4. The transmission power of the drum gear coupling is as high as 5%.According to the characteristics of the classics, nowadays, drum-shaped gears have been used throughout the country to replace straight-tooth couplings.

GIICL type—drum gear coupling is divided into 4 pieces, 2 pieces of outer gear ring, 2 pieces of inner gear ring, the inner gear ring is narrow, and the center of the two halves of the coupling has an O-ring seal. Tighten the reaming hole bolts, and drill an oil injection hole outside any outer gear ring.There is an O-ring seal in the rear end of the inner gear ring of the two halves of the coupling, and the tooth surface is quenched and tempered. The process is generally to first use a lathe to make the teeth, then drill and install.

Drum-shaped gear bushing tooth profile processing, from the initial manual, electric pulse, hydraulic profiling to comprehensive CNC processing, the accuracy can fully meet the planning requirements.

Nitriding treatment can be carried out when hard tooth surface is required, and high-quality low-carbon alloy steel can be used for carburizing and quenching and grinding or scraping with an alloy knife to meet the planning requirements.The load capacity and life of the diaphragm coupling depend on the touch strength, and the tooth surface curvature radius and tooth engagement angle directly affect the touch strength. The following is the relationship between the tooth engagement angle and the radius of curvature and the touch strength. Let's see the tooth surface curvature radius The meshing angle of the tooth directly affects the touch stress, the smaller the meshing angle, the larger the radius of curvature, and the larger the radius of curvature, the smaller the touch stress.

Innovative planning and analysis of diaphragm coupling

The vulnerable part of the diaphragm coupling is the diaphragm assembly.The service life of the diaphragm assembly determines the service life and operating power of the coupling.

Domestically produced diaphragm couplings have a certain distance from foreign products in terms of appearance, quality and service life.For this reason, the researchers conducted research on the diaphragm coupling [1-5], but some of the effects were only the results of theoretical research, and no good solutions were proposed for the structure of the diaphragm assembly. Other effects were only for a special Structural diaphragms (such as circular diaphragms) are discussed, or only a single diaphragm is analyzed, and the conclusions drawn from this are not universal.From the practical damage of the diaphragm group and theoretical analysis [1飊5], it can be seen that the damage of the diaphragm assembly mainly occurs in the vicinity of the hinge point of the diaphragm group.The vulnerable part of the diaphragm coupling is the diaphragm assembly.The service life of the diaphragm assembly determines the service life and operating power of the coupling.This is because when there is a viewpoint displacement and axial displacement between the power machine and the working machine, additional stress will occur in the diaphragm group in the diaphragm coupling that connects the power machine and the working machine.When the diaphragm coupling is in high-speed work or repeated forward rotation, the diaphragm group is subjected to the effect of alternating stress, which is prone to fatigue and damage.In order to specifically analyze the cause of the diaphragm group damage, the service life of the extended diaphragm coupling, take the waist-shaped diaphragm as an example, first determine the structure of the diaphragm group according to the TRIZ theory, and then use CosmosWorks to analyze the strength of the diaphragm group Analyze and compare the traditional diaphragm group and the patch diaphragm group.
