The radial movement of the star-shaped elastic coupling due to the centrifugal force during high-speed operation will accelerate its wear, and a shell is added.In addition to preventing dust and oil storage, insufficient thinning may cause interference. Excessive thinning will weaken the strength of the tooth, and the backlash will be very...
The maximum allowable axis error of the two shafts of the plum blossom flexible coupling shall not be greater than the provisions of Table 5-107.The maximum amount of operating compensation refers to: vibration, shock, deformation, temperature change caused by manufacturing errors, installation errors, and changes in working load that are allowed in the working state...
The reduction in volume and wire size of steel during solidification and cooling is called shrinkage.It has a great influence on the formation of defects such as hot cracking, shrinkage cavity and porosity of the cast billet (steel ingot).The shrinkage during the solidification of molten steel, if according to its shrinkage...
1) Aging treatment.After solution treatment or quenching, the workpiece is kept at room temperature or an appropriate temperature higher than room temperature to achieve the purpose of precipitation hardening.The natural aging at room temperature is called natural aging, and the artificial aging at high temperature is called artificial aging.It can make the size and sex of parts...
The definition of diaphragm coupling: a coupling that uses thin springs to connect with the two halves of the coupling by bolts or other coupling methods to realize the elastic connection of the two shafts. Several sets of diaphragms (stainless steel sheets) are staggered with bolts The ground is connected with the two halves of the coupling, and each set of diaphragms is...
Coupling finding is one of the important tasks of machine installation. The purpose of alignment is to make the center lines of the driving shaft and the driven shaft on the same straight line when the machine is working. The accuracy of alignment is related to whether the machine can Normal operation is especially important for high-speed machines...
