Description

Technical Field

[0001] The utility model relates to the technical field of reducers, in particular to a braking reducer. Background Art

[0002] A brake reducer is a mechanical device that is mainly used to reduce the rotation speed and generate braking force. It is widely used in various mechanical equipment. Its working principle is to reduce the speed of the rotating object by reducing friction, thereby achieving the purpose of deceleration. A brake reducer usually consists of two main parts: one is the reducer housing, which is used to accommodate and fix the reducer; the other is the reducer gear set, which is composed of multiple gears and reduces the speed through meshing transmission. During the deceleration process, due to the different friction between the two sets of contact surfaces, the heat energy generated can be dissipated through the heat sink to ensure the stability of the braking system. The advantages of the brake reducer are simple structure, small size, light weight, low manufacturing and use costs, etc. It can effectively improve the operating efficiency and safety of the equipment and reduce energy waste. At the same time, the brake reducer has good versatility and adjustability, and can be designed and customized according to specific needs.

[0003] During the use of existing reducers, heat is usually dissipated through the heat dissipation holes. After long-term use, some dust will enter the interior of the brake reducer through the heat dissipation holes, which will have a certain impact on the driving efficiency of the reducer, because the presence of dust will hinder the smooth operation of the internal parts of the machine, thereby causing the efficiency of the entire machine to decrease. At present, the reducer is usually protected by installing a protective shell on the outside of the reducer. The protective shell can only protect the outside of the reducer. When the reducer is hit by a collision, it will vibrate, which will cause the internal parts of the reducer to loosen and be damaged.

[0004] Therefore, it is necessary to provide a new brake reducer to solve the above technical problems. Utility Model Content
