    Buffer and vibration absorption of the pin coupling is realized by elastic elements

      Load changes are often reflected in periodic loads, impact loads and irregularly changing loads. Elastic couplings can adapt to load fluctuations and have the ability to cushion and dampen vibrations, which are mainly related to the stiffness and damping of the elastic coupling.The stiffness of the coupling includes radial stiffness, axial stiffness and torsional stiffness. ..

    Causes of vehicle vibration caused by unbalanced drive shafts and how to eliminate them

      Tighten the front wheel of the car with mats, use a jack to lift the middle and rear drive axles on one side of the car, start the engine, put on high gear, and observe the vibration of the drive shaft.During the observation, notice that when the speed drops, if the shimmy increases significantly, it indicates that the drive shaft is bent or the flange is skewed.The bending of the drive shaft is the bending of the shaft tube, most of..

    Gear coupling contact conditions and angle wear

      The spherical center is on the gear axis, and the tooth side clearance is larger than that of general gears. The drum-shaped gear coupling can allow a larger angular displacement (compared to the straight gear coupling), which can improve the contact conditions of the teeth and transmit torque. Ability to extend service life.The contact state along the tooth width when there is angular displacement.Gear couplings are developing in our country...

    The reason why the universal coupling cannot be lubricated by adding grease

      Because the toughness of the grease film is poor, the universal joint has to accept larger torque and alternating loads during work, so it is difficult to form a good oil film in the bearing.Therefore, grease should not be used for the smoothness of the cross universal joint, but gear oil should be added.Calcium-based smoothing grease is composed of thickener calcium and root smoothing oil..

    Optimized design of pin coupling to enhance function

      The pin coupling is a pin made of a number of non-metal elastic materials, placed in the flange holes of the two coupling halves, and the two halves of the coupling are connected by the pin. The pin coupling has a simple and easy structure. It is more convenient to manufacture, assemble, disassemble and replace the elastic element, without moving the two couplings.The material of the elastic element (column pin) XNUMX..

    Manufacturing Technology of Automobile Right Drive Shaft

      The right drive shaft is a shaft that can transmit power among the drive shafts of the universal transmission device.It is a rotating body with high speed and less support, so its dynamic balance is very important.Generally, the drive shaft must undergo a dynamic balance test before leaving the factory and be adjusted on a balance machine.For front-engine rear-wheel drive..

    Several matters needing attention when adjusting and aligning diaphragm coupling

      1. If the concentricity of the diaphragm coupling is tested before the anchor bolts are tightened, there is no need to rush to remove the measuring tool after adjustment.Because in the process of tightening the anchor bolts, due to improper tightening methods, or the horns near the anchor bolts are not supported, the installation accuracy after tightening will change..

    The structure and technology of the motor shaft

      Adequate strength and rigidity are the prerequisites for the reliable operation of the motor shaft, especially for large and medium-sized motors, which should be strictly checked or demonstrated according to actual working conditions.However, in addition to this, the manufacturability of the motor shaft structure must also be taken seriously when designing the motor shaft. People often ignore it, which seriously affects the machining accuracy and processing..
