Rigid couplings are divided into flange couplings, radial key flange couplings, sleeve couplings, clamp couplings and parallel shaft couplings.The material of the flange coupling can be gray cast iron and carbon steel, and cast steel or forged steel should be used for heavy load or when the peripheral speed is greater than 30 m/s. ...
The movable connection formed between the component parts of the movable rigid coupling has a degree of mobility in a certain direction or several directions, so it can compensate the relative displacement of the two shafts.Commonly used removable rigid couplings are as follows: (1) Gear coupling...
Couplings and clutches are used for the connection between the shaft and the shaft to transmit motion and torque.The main difference between the coupling and the clutch is that the two shafts connected by the coupling can only be separated by white disassembly after the machine stops; while the two shafts connected by the clutch...
Cast iron is divided into gray cast iron, nodular cast iron, and malleable cast iron.Gray cast iron: good fluidity, small body shrinkage and linear shrinkage.The comprehensive mechanical properties are low, and the compressive strength is about 3-4 times higher than the tensile strength.Good vibration absorption.The modulus of elasticity is low. ...
Round steel is divided into three types: hot rolled, forged and cold drawn.The difference between round steel and other steel bars is as follows: 1. The shape of round steel is different. Round steel is smooth and round, without grains or ribs. Other steel bars have engraved or ribbed appearance on the surface, which results in the bonding of round steel and concrete. Small, and other...
