    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..

    The working speed of the coupling and the centrifugal force caused by it

      The universal coupling has a large carrying capacity.Compared with other types of couplings with the same rotating diameter, the torque transmitted by it is greater. This is a mechanical device with a restricted rotating diameter.The working speed of the coupling and the centrifugal force caused by it.For high-speed drive shafts, couplings with high balance accuracy should be selected..

    Causes and diagnosis of abnormal noise of transmission shaft

      1. The flange joints (or connecting bolts) of the drive shaft are loose, causing abnormal noise. 2. Lubricating grease nipple (commonly known as grease nipple), cross shaft oil passage is blocked and no grease can be injected, grease is not filled on schedule, cross shaft oil seal is damaged and oil leakage, etc., cause cross shaft needle roller bearings in the long-term Lack of lubrication...

    The relationship between diaphragm coupling and radial deviation

      In the design and manufacture of equipment that wants to keep the radial deviation close to zero, a single diaphragm (short type) coupling is generally used.However, this is actually an important reason for the failure.Even if you are confident in the installation accuracy, for servo machinery, it is still recommended to use a double diaphragm (long type) coupling.
