    Provisions for disassembly, maintenance and lubrication of cardan shafts

      For the types of cardan shafts currently used, gear couplings can be used for high-power light-load transmission systems, and for transmission systems requiring heavy impact loads and shaft torsional vibrations, tire couplings can be used with higher ductility. For the equipment, the operating speed and centripetal force of the cardan shaft are higher, and the high-speed rotating shaft should be used with a balanced high..

    Application of diaphragm coupling in industry

      The characteristic of the diaphragm coupling is a bit like a bellows coupling, in fact the way the coupling transmits torque is similar.The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to 1.5 degrees of deviation, and at the same time produce a lower bearing in the servo system..

    Does the abnormal noise of the drive shaft need to be replaced?

      1. When the speed of the car changes suddenly and there is a metal knock on the transmission shaft, it can indicate that the individual flanges or universal joint cross shaft bearings are too worn and loose, causing abnormal noise of the transmission shaft. 2. When the car starts, the drive shaft will make a "dang" sound or make a messy noise.When the car is reversing backwards on a gentle slope, it emits...

    Quenching and heat treatment of coupling

      Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing processes, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece, or changing the chemical composition of the surface of the workpiece , To give or improve the performance of the workpiece.Its characteristics:

    Deviation and transmission torque of universal coupling during installation

      Flexible couplings without elastic elements can not only transmit motion and torque, but also have different degrees of axial, radial and angular compensation performance, including gear couplings, universal couplings, and chain couplings , Slider coupling, etc.Flexible couplings with elastic elements can transmit motion and torque, and have different ranges..

    How a cost-effective drive shaft can reduce battery costs for electric vehicles

      The regenerative strategies of hybrid and electric vehicles may have an impact on the requirements of the drivetrain.There are two key issues.How much energy can be collected from the street, and how much energy can the transmission system really recover?The electric transmission system not only transmits power from the differential to the wheels, but also transmits negative torque..

    The form of diaphragm coupling and its operating characteristics

      A polygon is formed by a single thin rod. The rod has a simple shape and is convenient to manufacture, but requires the pitch of each hole. Its working performance is basically the same as that of a continuous polygonal ring, but the strength and speed are lower, which is suitable for occasions where the size of the coupling is restricted. . 1. It can be assembled and disassembled in 2 hours without interfering with the master-slave device.

    Diaphragm coupling lubrication area and normal function

      For flexible and toothed couplings, some are lubricated with grease.That is, when the coupling is working, it can be lubricated due to the squeeze of grease.When assembling, it is coated with grease and there is sufficient lubrication inside.The grease used in high-speed devices will not separate the oil and soap under the action of centrifugal force, otherwise the coupling will leak oil..

    Coupling is an important device on large transmission equipment

      Couplings have higher requirements for the quality of lubricating oil and higher requirements for flow, so they must be checked and relubricated from time to time; although it is more troublesome, the distance that it can transmit is relatively large.And if the shrapnel type is used, although it is also sealed, it is not demanding and can be adjusted according to the actual situation..
