zihuoli spring manufacture various barrel springs.
barrel springs have a wide range of applications. one of most import function of the barrel springs is preventing bending. when the length of the compression spring is 4 times its width, the compression spring will bend when pression. for equal diameter compression spring, this can be prevented by placing the spring on the shaft or in a hole. if this is not possible, barrel springs can be used. barrel springs have a wider shape center than both ends, allowing pressure to be distributed in different ways and providing stability for longer compression springs. if you are interested in testing this theory, take out a compression spring four times (or more) long and compress it by hand. when the pressure is too high, the spring will bend under the pressure, causing the center of the spring to protrude outward and finally shoot out under the pressure.
when the solid height decreases, the compression spring will produce a force in a linear direction, which is suitable for most designs where barrel springs can be used. however, the problem with compression springs is that design constraints can lead to entity height conflicts. for example, you need a spring to withstａnd a force that requires multiple coils. when compressed, these coils will be wound around each other until they can no longer be compressed. this is called the solid height. this may be a problem in your design. in this case, another option is to use a barrel spring to stretch the smaller coils at the top and bottom of the spring into the larger coil in the center of the spring, thereby reducing the solid height.
industries that use barrel springs include the auto industry, the toy industry, and the furniture industry. if you need to customize the barrel spring for your product, please contact us sales
