1) Single-sided unbalanced state If the center of gravity of the object is not on the axis of rotation, a single-sided unbalanced state will appear.At this time, regardless of the relative position between the object and the axis, it will not be in a static equilibrium state.Place the journal of the unbalanced object on two parallel horizontal rods or guide rails, and you can observe the single...

The alkaline blackening liquid used has low efficiency and high energy consumption, especially when dealing with cast iron, it is easy to appear khaki, and the appearance often fails to meet the customer's satisfaction. It is blackened at room temperature.Coupling castings due to the particularity of the manufacturing process, the surface of the casting is easy to rust, and it is difficult to handle after rust. If it does not cause...

More than 90% of the oil leakage problems are caused by the fact that the rubber sealing ring has been exposed to the temperature of the cold and warm for a long time, causing the sealing ring to lose a lot of plasticizers and softeners, and the problem of corrosion, aging and hardening occurs. At first it was oil leakage, and slowly began to drip oil. Over time, it became dense..

Process power equipment, especially turbo-compressor units, due to thermal expansion and contraction, the position of the rotor will change from cold to hot or from hot to cold.In addition, due to the uneven settlement of the foundation, the deformation of the unit after being loaded, and other factors will cause the unit's misalignment, although these misalignments can be corrected by aligning..

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. ..

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..

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...
