What Does The Key Link In The Amusement Rides Parks Equipment Mean?
1.Key connection.The key connection is the most widely used shaft-hub connection, which is simple in structure, convenient in disassembly and assembly, and reliable in operation.The key connection is divided into four types: flat key connection, semicircular key connection, wedge key connection and tangential key connection.
Flat key connection. Commonly used flat keys include ordinary flat keys (Please check Figure 2-90), thin flat keys, guide flat keys and sliding keys. Ordinary flat keys and thin flat keys will be used for static connection, what’s more, guide flat keys and sliding keys are used for dynamic connection.
2.Semicircle key connection.The semicircular key is a semicircular plate-like part, please check Figure 2-91, and it also relies on the side of the key to transmit torque.
Wedge key connection. The wedge key connection is shown in Figure 2-92. The upper and lower surfaces of the wedge key are all working surfaces,and its avarage sufface of the inclination will be 1：100 between the upper surface of the key and its match surface of hub keyway.
4.Tangential key connection. The tangential key consists of a pair of wedge keys with an inclination of 1:100. During assembly, the two wedge keys are driven from both ends of the hub and wedged tightly.
5.Spline connection. What we called spline connection is a kind of connection which formed by formed by the meshing of multiple key teeth evenly distributed along the circumference of the shaft and the hub hole. The former is called external spline and the latter is called internal spline, as shown in Figure 2-94. Spline connections can be used for both static and dynamic connections.Application range:amusement park、playground、theme park、game center.
