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...
Rigid couplings have two main structural forms: ① Relying on reamed holes and bolts to achieve two-axis alignment and relying on bolt rods to bear extrusion and shear to transmit torque; ...
The flange coupling is a rigid coupling, which requires high neutrality of the two shafts. When the relative displacement of the two shafts exists, it will cause additional loads in the machine parts and worsen the working conditions. The main disadvantage.Advantages: But due to the simple structure and low cost,...
The allowable speed range of the coupling is determined by accurate calculations based on the maximum outer edge size of the allowable linear speed of different materials of the coupling...
Couplings, also known as couplings, are mainly used to connect the transmission shafts of various mechanisms. Due to different mechanical equipment, the functions of various couplings are also slightly different. For example, on a forklift, the coupling is used to transmit the transmission and drive. The power between the bridges...
Flange coupling is a rigid coupling. It connects two half couplings with flanges to the two shafts with ordinary flat keys, and then connects the two half couplings with bolts to transmit motion. And torque...
The middle tenon flange coupling is a rigid transmission part. It connects two flanged semi-transmission parts with ordinary flat keys to the two shafts, and then connects them with bolts to transmit motion and torque... .
