Shaft coupling refers to a device that connects two shafts or a shaft and a rotating part, and rotates together in the process of transmitting movement and power, and does not disengage under normal conditions. Sometimes shaft coupling is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. Let us learn more detailed information about shaft couplings. l What are the types of shaft coupling? l What are the features of shaft coupling? l What is the future of shaft coupling? What are the types of shaft coupling? Shaft couplings can be divided into two categories: rigid couplings and flexible couplings. Rigid couplings do not have the ability to buffer and the ability to compensate for the relative displacement of the two axes, which requires strict alignment of the two axes. However, rigid coupling has simple structure, low manufacturing cost, convenient assembly and disassembly and maintenance, and can ensure that the two axes have the neutrality of the transmission is greater. Rigid couplings can be used in flange couplings, sleeve couplings and clamp couplings. Flexible couplings can be further divided into flexible couplings without elastic elements and flexible couplings with elastic elements. The former type only has the ability to compensate the relative displacement of the two axes, but it cannot buffer and dampen vibrations, which is commonly used in slider couplings, gear couplings, universal couplings and chain couplings. Because the latter type contains elastic elements, in addition to the ability to compensate for the relative displacement of the two axes, flexible couplings with elastic elements also has the ability of buffering and dampening. However, it is worse than the flexible coupling without elastic elements for the torque is limited by the strength of the flexible element. Flexible couplings with elastic elements commonly are the part of elastic sleeve pin couplings, elastic pin couplings, plum-shaped couplings, tire couplings, serpentine spring couplings and reed couplings. What are the features of shaft coupling? The functions of shaft couplings can be described as follows: Shaft couplings have the ability of buffering, dampening, and improving the dynamic performance of the shaft system. Shaft coupling refers to a device that connects two shafts or shafts and rotating parts, and rotates together in the process of transmitting movement and power, and does not disengage under normal conditions. Sometimes shaft coupling is also used as a safety device to prevent the connected parts from being subjected to excessive loads and play a role in overload protection. Shaft coupling is often composed of two halves, which are connected by a key or tight fit respectively, and fastened to the ends of the two shafts, and then the two halves are connected in some way. The shaft coupling can also compensate the deviation between the two shaf...

Ideals do not change, and we look forward to a new chapter together. Our company will be 7 days holiday from Oct 1st to Oct 7th to celebrate the National Day.

Intermediate shaft of the universal joint is generally divided into left and right parts to adapt to different working conditions.If spline connection, the mutual position of the fork surfaces at both ends can be adjusted by changing the assembly relationship of the splines.The reasonable universal joint transmission design can reliably transmit power, suppress the vibration generated in the transmission, and ensure that the two shafts rotate at the same speed and transmit the same torque as much as possible.Therefore, it is necessary to perform theoretical modeling and simulation analysis on the dynamic characteristics of universal joints. The universal joint is composed of two single joints and an intermediate shaft, which can realize the connection of two axes that are intersecting, parallel or spatially staggered, and realize the movement and power transmission between the two shaft couplings.It plays an extremely important role in the development of mechanical engineering and the automotive industry.As the angular velocity of single joint the driven shaft changes periodically, additional dynamic loads will be generated in the transmission, causing the shaft to vibrate.If use universal joints can eliminate this disadvantage. Should be carefully check installation of pneumatic clutches, main motors, and universal joint reduction gears to remove abrasions and burrs generated during transportation.Install only after cleaning.Should according to the instructions provided by the manufacturer to install the main motor. Not only the coaxiality and inclination of the main motor universal transmission shaft should same as the transmission shaft of small gear device,that is 1/1000, but also the inclination direction of the ball wear. If there is an error in the inclination and height, you can add a spacer under the motor base to adjust it.If there is an error in the parallelism, the rotor bearing position of the movable motor should be carefully adjusted to achieve high accuracy.When installing a low-speed device, after installing a planetary cycloid reducer with a motor, need sure that device can easily move the claw clutch without jamming, disengaging, or tilting. Link point and disconnection between the limit switch and the stopper are reliable.The surface of the axially moving semi-universal coupling, the link surface between the slider of lever device and the matching groove should be coated with grease.The parallelism between the ball mill pinion shaft and the cylindrical shaft must not exceed 0.15 / 1000.When installing the universal joint gear cover, check whether the gear cover has been deformed during long-distance transportation, whether the oil-resistant paint has fallen off,if its fallen off ,should paint again. When installing the gear cover, pay attention to inspection and correction to ensure that the gear does not collide when its running. When the ring rotates, the felt ring should closely fit the large gear, not allowed gap.
