Description

Technical Field

[0001] The utility model relates to the technical field of brake mechanisms, in particular to a novel brake structure. Background Art

[0002] The turntable brake mechanism is like the brake of a car, which is related to the function of the turntable. The brakes currently used on the market (such as the brakes in the manual) Figure 6 (As shown), a large portion of them use disc brakes, which allow air or oil to enter a sealed chamber, pushing the piston to reciprocate, squeezing the outer circumference of the extremely thin brake pad. A certain gap is maintained between the brake pad and the rotating shaft. When the air or oil pressure reaches a certain level, the deformation of the brake pad exceeds the gap between the rotating shaft and the brake pad, and the brake pad will partially stick to the stationary part. The rotation of the rotating shaft stops due to the friction resistance between the brake pad and the stationary part. When the air or oil is stopped, the elastic element pushes the piston back, causing the piston and brake pad to disengage. This type of brake has very high requirements for brake pad processing. Good contact must be achieved when squeezed to ensure good braking performance. Otherwise, it is easy to cause actual point contact during braking. The thin brake pad itself is easily deformed during the heat treatment process. If the initial gap is not set properly, local scratches will easily occur, causing abnormal operation noise. Therefore, the utility model proposes a new brake structure. Utility Model Content
