　　First, check visually to confirm whether the coupling has signs of wear or fatigue, and then clean the coupling; then, if the coupling needs lubrication, check and replace the lubricating oil. Most couplings only need to be replaced once a year lubricating oil. ...

　　The ZL-type elastic pin gear coupling is a pin made of several non-metallic materials and placed in the mating hole between the two coupling halves and the inner surface of the outer ring; the two pins are used to transmit torque. Half coupling is connected. ...

　　Tire coupling tire body is one of the necessary spare parts of tire coupling, corresponding to UL, LA, LB tire body.Tire couplings are divided into two categories: convex type and concave type. The convex type is divided into three types: integral type with frame, integral type without bone and radial cut type. ...

　　Advantages of double-threaded couplings: 1. It is a double-threaded type; 2. Easy to install, maintenance-free, oil and corrosion resistant; 3. Good elasticity, better protection of equipment; 4. Vibration, compensation for radial and angular Tolerance and shaft deviation are better than single thread;...

　　In recent years, couplings have been increasingly used in precision machinery controlled by servo systems, such as machine tools and semiconductor system manufacturing machinery.In these fields, different from general manufacturing machinery, the coupling must require its output relative to the input to have...

　　Commonly used star elastic couplings are divided into basic star couplings, expanded shaft hole star couplings, double elastic star couplings, flanged star elastic couplings, and belt systems. Moving wheel type star-shaped elastic coupling, with brake disc type star-shaped elastic coupling. ...

　　There is no elastic body in the middle of the JQ type clamp shell coupling. It is usually a lifting ring. The shaft at both ends is suspended. The diameter of the shaft hole is the diameter. It is generally used for vertical installation. The middle part is slotted with a suspension ring to block the equipment at both ends. Shaft head to transmit torque. ...

　　Gear coupling processing method: This kind of fault processing is more difficult, and it needs to stop production, that is, re-align, or re-align the reducer side, or re-align the reel side. ...

　　The backstop is a device that prevents reversal and supports the heavy objects from moving.Its main functions are: ①Supporting heavy objects for a long time (supporting function); ②Only allowing the mechanism to move in one direction, acting as a stopper; ③Allowing the mechanism to move freely in one direction and limiting the speed in the reverse direction...

　　The iron and steel industry is the basic industry of the national economy. It is a technology, capital, resource, energy, and labor-intensive industry, but at the same time it is one of the industries with the most serious overcapacity and the greatest impact. ...
