Introduction to the bolt selection of universal couplings and the height of the external teeth of the coupling

　　Universal coupling is a type of coupling, and there are many types of couplings.So, what is the bolt selection of the universal joint and the height of the external teeth? The following is a small version of the coupling content, I hope you can have a harvest!

　　Mingtong Transmission Machinery Manufacturing Co., Ltd. specializes in the production of universal joints.

　　The universal coupling has various structures, a wide range of applications, and a variety of materials.This is one of the elastic models.Commonly used materials for couplings are gray cast iron, cast steel and aluminum alloy.The universal coupling has a simple structure, no lubrication, convenient maintenance and repair, and can be used continuously for a long time.The high-strength polyurethane elastic elements are wear-resistant, oil-resistant, large carrying capacity, long service life, safe and reliable. Stable and reliable, with good damping and electrical insulation properties.It has large axial, radial and angular compensation capabilities.The utility model has simple structure, small radial size, light weight and small moment of inertia.Suitable for medium and high speed occasions.Machine tools are widely used in CNC machine tools, CNC machining, machining centers, machine tools, CNC milling machines, computers and other fields.Metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, lifting machinery, transportation machinery, light industry machinery, textile machinery, pumps, fans, etc.

　　Universal coupling is a widely used coupling, also known as quasi-coupling, composed of two metal plates and an elastic body.These two metal plates are generally 45 steel, but when the load is sensitive, aluminum alloy can also be used.

　　Universal couplings are usually made of engineering plastics or rubber.The life of the coupling is also called the elastic life.Because elasticity is under pressure, it is obviously pulled out.The general's life span is 10 years.Since elasticity has the effect of re-vibration and damping, it is used under strong vibration conditions.The performance limit temperature determines the working temperature of the coupling, and its working temperature is generally between -35 and 80 degrees.

　　Universal joints have excellent balance performance and are suitable for high-speed applications (up to 30,000 rpm), but cannot handle large deviations, especially axial deviations.Larger eccentricity and inclination result in greater bearing load than other servo couplings.

　　The universal coupling has a simple structure, no lubrication, convenient maintenance and repair, and can be used continuously for a long time.The high-strength polyurethane elastic element is wear-resistant, oil-resistant, large carrying capacity, long service life, safe and reliable. It is stable and reliable, has good damping and electrical insulation properties.It has large axial, radial and angular compensation capabilities.The utility model has simple structure, small radial size, light weight and small moment of inertia.Suitable for medium and high speed occasions.

　　The universal coupling has a simple structure, a small number of zeros, a small radial dimension, does not require lubrication, and the elastic element has a high load-bearing capacity.In addition to the elastic coupling in the shape of the double-flanged aluminum sheet, when replacing the elastic part of the fragile aluminum sheet shape, the semi-coupling needs to be moved in the axial direction.Coupling can compensate for the relative deviation of the two axes.The existing universal couplings of Baotou Mingtong Transmission Machinery Manufacturing Co., Ltd. adopt CNC lathe and CNC milling processing technology. The products have fine workmanship, high precision and more reliable performance.

　　The specific characteristics of universal couplings are introduced:

　　(1)Compact, no gap, provide three kinds of elastomers with different hardness

　　(2) Absorb vibration and compensate radial and angular deviation

　　(3) Simple structure, convenient maintenance and inspection

　　(4) No maintenance, oil resistance and electrical insulation, working temperature 20°c-60°c

　　(5) There are four, six, eight and ten kinds of plum blossoms.

　　(6) There are top line, flat line and fixed line.

　　The bolts use universal couplings and couplings with the height of the external gear

　　The universal coupling uses high-strength bolts and self-locking nuts to connect the flanges at both ends with other mechanical parts, and its torque is transmitted through the friction between the flange end key and the flange.

　　The universal coupling uses high-strength bolts and self-locking nuts to connect both ends of the flange to other mechanical parts.The torque is transmitted by the friction between the flange end key and the flange.The bolts can only be placed from the flange side of the coupling.The nut is tightened on the flange side of the universal coupling.The mechanical properties of bolts meet the 3098.1 grade in gb 10.9, and the mechanical properties of nuts should meet the requirements of gb 3098.4. 10.In this way, the shafts can be well connected.

　　The height of the inner ring gear of the coupling cannot be changed at will. The main reason is that the gear stroke is limited and the height of the inner ring gear is too high, which causes the bed not to dry and the gear is processed in the gearbox.It affects productivity and increases costs.The designer of the coupling factory clearly stipulates that the height of the inner ring gear of the coupling shall not exceed 80, and it is limited to gears with an outer diameter of less than 300.The inner ring with an inner ring outer diameter of 300 or more will have a pressure cover, so that you can remove the cover first and process it with wire cutting instead of gear processing.

　　A mechanical part in which a universal coupling is used to connect two different mechanisms (active mechanism and driving part) so that they can transmit torque together.In high-speed and heavy-load power transmission, some have the function of damping vibration and improving dynamic performance.The coupling consists of two parts, which are respectively connected with the driving shaft and the transmission shaft.Most of the power machinery is connected to the working machine through couplings.

　　The content of coupling is described above.After reading it, everyone should have a certain understanding of it.Interested friends can learn more about other couplings we have collected.
