    The core advantage of using forgings instead of castings for universal joint yokes
    The core advantage of using forgings instead of castings for universal joint yokes lies in their denser internal structure and mechanical properties, which can better adapt to the complex stress conditions when the universal joint transmits torque. Stronger Mechanical Properties Forging refines metal grains through plastic deformation and aligns the grain flow with the direction of stress. As a result, forgings have much higher tensile strength, yield strength, and impact toughness than castings, and are less prone to fracture under alternating loads. Fewer Internal Defects Castings are susceptible to defects such as blowholes, shrinkage cavities, and sand inclusions, while forging can eliminate problems like looseness and porosity in raw metal materials, improving the structural integrity and reliability of the yoke. Better Fatigue Resistance During operation, universal joints undergo repeated angular swings and torque impacts. The uniform structure of forgings gives them significantly longer fatigue life than castings, thereby extending the overall service life of the universal joint. The universal shaft forging fork head produced by our company has a performance. If you are interested, please feel free to contact us.

    What is the general tolerance of the motor shaft and the coupling
    The tolerances of the motor shaft and the coupling are generally controlled within the range of 0.01mm to 0.05mm, which is within the normal range. The specific tolerance values are influenced by the manufacturing accuracy of the parts and the assembly technology, as well as factors such as the thermal expansion and contraction of the shaft material during rotation. The motor shaft and the coupling are crucial connecting components in mechanical equipment. The tolerance fit between them directly affects the operating efficiency and service life of the equipment. So, what are the typical tolerances for the motor shaft and the coupling? I. General Range of Tolerance The tolerance between the motor shaft and the coupling is mainly influenced by the manufacturing accuracy of the parts and the assembly technique. In general, a tolerance within the range of 0.01mm to 0.05mm is considered a normal range. This range ensures a tight fit between the shaft and the coupling, reduces wear, and improves the transmission efficiency. II. Factors Affecting ToleranceII. Factors Affecting Tolerance 1. Manufacturing accuracy of components: During the manufacturing process of the motor shaft and the coupling, the dimensional accuracy will be influenced by various factors such as the processing equipment, manufacturing methods, and material properties. The higher the manufacturing accuracy, the smaller the tolerance range and the higher the mating accuracy. 2. Assembly technology: During the assembly process, ensuring the correct mating between the shaft and the coupling is also crucial. Appropriate assembly techniques and methods can ensure that the tolerance remains within control, thereby improving the overall performance of the equipment. III. Common Tolerance Standards for Matching In practical applications, the matching tolerance between the motor shaft and the coupling is also selected based on specific requirements and usage conditions. For example, common tolerance standards include H7/d6, H7/D7, and H7/C9, etc. These standards are respectively applicable to different precision and rotational speed requirements of coupling connections, ensuring that the interference fit or clearance fit between the shaft and the hole meets the design requirements. IV. Importance of Correctly Selecting Tolerance Correctly selecting the matching tolerance between the motor shaft and the coupling is of great significance for improving the accuracy, stability, and lifespan of the equipment. An overly tight fit may cause assembly difficulties, increased wear, and even shaft breakage; while an overly loose fit may result in uneven torque transmission, increased vibration, and decreased sealing performance. Therefore, when choosing the tolerance, various factors should be considered comprehensively to ensure the optimal performance of the equipment.

    Advantages of star-type couplings
    The application scope of star-type coupling is very extensive. Before using it, we definitely need to know the advantages of star-type coupling so that we can apply it better. If you are interested in this topic, then let's take a look together. We hope it can be helpful to some relevant people.  Star-type couplings are widely used in various industries, so their application scope is undoubtedly extensive. In fact, star-type couplings are mainly made of engineering plastics as the elastic element and are suitable for connecting two coaxial shafts in the transmission system. They have the function of compensating for the relative offset of the two shafts and buffering, and have a wide range of applications. The torque they can transmit is 20-35000.N.M. I'm sure you have noticed when using it. In fact, its working temperature is -35-80 degrees Celsius, and it can be interchanged with the German ROTEX coupling. The polyurethane elastic body is made into protruding claws, which can avoid internal deformation caused by impact and external deformation caused by centrifugal force. The large concave surface of the protruding claws makes the surface pressure of the involute gear very small. Even if the tooth surface is overloaded, the fixed teeth will not wear or deform. Moreover, it has excellent failure resistance; the star-type coupling is also insensitive to impact loads and pressure peaks; it has high corrosion resistance; low compression deformation; is suitable for harsh working conditions; and is easy to install.  The star-type coupling is currently used as the drum-shaped tooth coupling of the transmission device. It evolved from the ordinary positive gear coupling. The drum-shaped star-type coupling has been applied in many advanced industrial countries abroad. The standard and series products consist of two drum-shaped outer gear sleeves and a pair of straight tooth inner gear rings and other components. During operation, the torque is mainly transmitted through the inner and outer gear pressure plates. The straight tooth inner crown shaft of the drum-shaped outer gear sleeve rotates (referred to as angular acceleration) to compensate for the relative deviation and transmit the two shafts. Especially, the larger the protrusion in the tooth length direction, the greater the angular acceleration, up to 6°. Generally, it is recommended to be 1° to 1.5°, while the old-style star-type coupling only allows 0.5°. From the perspective of tensile strength and penetration ability, in the same working conditions, the torque transmitted by the crown coupling can be increased by 15-20%. It improves the contact state of the outer gear, avoids the disadvantages of being directly squeezed by the straight teeth and stress concentration under angular displacement, and also improves friction and tooth surface wear, reduces noise, and has a long maintenance cycle.

    Three-coordinate measurement of keyway shape and position tolerance
    The function of using a CMM to detect the geometric tolerances of couplings is mainly reflected in the following aspects: 1. Ensure Product Quality By detecting geometric tolerances such as coaxiality, parallelism, and roundness of couplings, it ensures that their geometric features meet the design requirements, avoiding functional failure of parts due to excessive geometric errors. For example, excessive coaxiality error will cause additional vibration and noise when the coupling transmits power, accelerating equipment wear. 2. Improve Assembly Precision Accurate geometric tolerance detection can provide data support for the assembly of couplings, ensuring the assembly precision between couplings and shafts, bearings and other components, making the mechanical cooperation during equipment operation closer, and reducing the risk of energy loss and component damage caused by assembly clearance. 3. Optimize Production Process Based on the detection results, problems existing in the production process, such as insufficient machine tool precision and wear of tooling fixtures, can be analyzed, so as to optimize processing technology parameters, improve equipment and tooling, and improve production efficiency and product consistency. 4. Support Fault Diagnosis When the equipment has faults such as vibration and abnormal noise, by using a CMM to detect the geometric tolerances of the coupling, it can be judged whether the fault is caused by the geometric error of the coupling, providing a basis for equipment fault diagnosis and maintenance, and shortening the fault troubleshooting time.
