Abstract： There are different types of brakes, and under different usage requirements
and working conditions, how can one choose a suitable and desirable brake? Next,
let me explain it to you, hoping it can be helpful to you. 1. The working nature and conditions of the machine or mechanism that needs
to be applied. For example, normally closed brakes are used for the lifting and
slewing mechanisms of cranes. For vehicles and lifting machinery operating
horizontally and rotating mechanisms, in order to control the magnitude of
dynamic torque for accurate parking, normally open brakes are often used. 2. Full attention should be paid to the task of the brake. For example,
there is sufficient margin for the braking torque of the object brake, which
should ensure a certain safety factor. For mechanisms with high safety
requirements, dual brakes need to be installed. For example, in a mine hoist, in
addition to setting brakes on the high-speed shaft, brakes are also installed on
the drum or rope shaft. For heavy object descent braking (i.e. sliding friction
braking), heat dissipation should be considered, with sufficient heat
dissipation area to dissipate the heat generated by the potential energy of the
heavy object during braking, in order to prevent overheating and brake
failure. 3. The application location should be considered. For example, if there is
sufficient space at the location where the brake is installed, an external
holding brake can be used. If the space is limited, an internal shoe, belt, or
disc brake can be used. Overall, the selection of brake type is mainly related to the working
conditions, and users need to choose according to the specific working
environment.
