There are different types of brakes. How can I buy a suitable brake under different usage requirements and working conditions?
1. The nature and working conditions of the machine or organization to be applied. For example, normally closed brakes must be used for the lifting and luffing mechanisms of the crane. For horizontally running vehicles and hoisting machinery and rotating mechanisms, in order to control the magnitude of the 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, the braking torque of the supporting article brake must have sufficient margin, that is, a certain safety factor should be ensured. For mechanisms with a high degree of safety, double brakes should be installed. Another example is a mine hoist, in addition to a brake on the high-speed shaft, a brake is also set on the drum or sheave shaft. For heavy load braking (ie sliding brake), heat dissipation should be considered. There must be enough heat dissipation area to dissipate the heat generated by the heavy level energy during braking, so as to avoid overheating and braking. Invalidate.
3. The place of application should be considered. For example, when there is enough space in the place where the brake is installed, an external brake can be selected, and where the space is limited, an in-shoe, band or disc brake can be used.
In general, the choice of brake type is mainly related to the work situation, and the user needs to choose according to the specific working environment.
