After the reduction of refined oil products is finalized, the retail price of 0# diesel in all provinces still maintains the "5 yuan era"; from the perspective of gasoline, the retail price of 92# gasoline in the provinces and cities that implement the National Five Standards is still maintained at more than 6 yuan, while the implementation of National IV Among the standard provinces, nearly 76% of the area 93# gasoline will re-enter...
The core-type elastic coupling is made of a number of combined rubber pins with steel rods or steel pipes in the center, and placed in the concave and non-through holes of the two halves of the coupling to realize the two halves of the coupling. Join. ...
Rigid couplings are divided into flange couplings, radial key flange couplings, sleeve couplings, clamp couplings and parallel shaft couplings.Flange coupling: A coupling that uses bolts to connect the flanges of the two halves of the coupling to realize the two-axis connection;...
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 tooth clutch is characterized by its simple structure and compactness.In order to improve the bending strength of the teeth and facilitate the joining, the external teeth can be made into short teeth.The toothed clutch should be engaged at a standstill or at a low speed difference. ...
