CouplingAnd the clutch is used for the connection between the shaft and the shaft to transmit movement 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 is stopped; while the two shafts connected by the clutch, except for a few (such as a dog clutch), require the machine to decelerate Or they can be joined or separated after parking. Most of them can be separated and joined at any time during the working process of the machine.
Couplings and clutches are commonly used components in mechanical transmission shaft systems, and most of them have been standardized and serialized.When designing, first select the appropriate type according to the working conditions and requirements, and then select the required model and size from the relevant standards or design according to the diameter, speed and calculated torque of the shaft.
There are many types of them. I will briefly introduce several commonly used couplings and clutches.
There are many types of couplings. According to whether they have compensation performance, the national standard divides the couplings into two categories: rigid couplings and flexible couplings.The fixed rigid coupling cannot compensate the relative displacement of the two shaft axes, and is suitable for the occasions where the two shafts can be accurately aligned and the load is stable.The movable rigid coupling uses the relative movement or gap between the parts to compensate for the relative displacement of the axis of the two shafts.
Commonly used couplings are: flange coupling, cross slide coupling, gear coupling, Wanhetong coupling, elastic pin coupling coupling, elastic sleeve pin coupling Couplings, plum blossom elastic couplings, star elastic couplings, diaphragm couplings, tire couplings, roller chain couplings, etc.
Commonly used clutches are: jaw clutch, disc friction clutch, overrunning clutch, safety clutch and so on.
