Abstract
The utility model discloses a generator brake. The generator brake comprises an air cylinder, a guide piston, a first working piston and a second working piston, wherein the guide piston, the first working piston and the second working piston are arranged in the air cylinder from top to bottom in sequence. A braking supporting plate is arranged on the top of the air cylinder, the guide piston is connected with the braking supporting plate, a braking gate is fixedly arranged on the braking supporting plate, the guide piston and the first working piston are respectively provided with a central hole along the central axis, and the guide piston and the first working piston are connected through a bolt penetrating through the central holes. According to the generator brake, interference to the first working piston and a sealing ring by the occurrence of a clamping stagnation phenomenon caused by the inclination of the guide piston is avoided, the sealing ring is not damaged, the fact that the piston falls freely and automatically resets well is ensured, evenness of the abrasion of the braking gate is also ensured, and the operation of the brake is stable.
Description
Technical field
The utility model relates to electrical generator fields, is specifically related to a kind of generator brake.
Background technique
Present vertical hydrogenerator break commonly used; be three piston air pressure homing position type breaks mostly; in use; when blast is cancelled behind the brake stop; through regular meeting the situation that the brake plunger clamping stagnation does not fall down taking place, at this moment need not prize with crowbar and beat and could fall, causes " O " RunddichtringO of core plug impaired; thereby produce the situation of blow-by of piston, need to improve.
The model utility content
In view of the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of generator brake that can avoid the piston run-off the straight and then cause phenomenon such as clamping stagnation.
To achieve these goals, a kind of generator brake of the present utility model, comprise cylinder and from top to bottom be successively set on described cylinder interior guide piston, first working piston and second working piston, described cylinder head is provided with the braking supporting plate, described guide piston is connected with described braking supporting plate, described braking supporting plate top is set with the braking flashboard, wherein, described guide piston and described first working piston are respectively arranged with center hole along central shaft, and described guide piston is connected by the bolt that passes described center hole with described first working piston.
As preferably, described center hole is that sectional shape is the shoulder hole of inverted "convex" shape.
As preferably, be provided with the elastic member for the power of transmission between described guide piston and described first working piston.
As preferably, described elastic member is a dish-shaped spring.
As preferably, described guide piston and the contacted cylinder inner wall of described first working piston are provided with a lining.
As preferably, be provided with " O " RunddichtringO of sealing usefulness between described lining and the described cylinder inner wall.
As preferably, be respectively arranged with boss and groove on described guide piston and the described braking supporting plate, described guide piston is connected with described braking supporting plate with the cooperation of described groove by described boss.
As preferably, described guide piston outer side wall is provided with feather key.
Compared with prior art, generator brake of the present utility model has avoided guide piston to tilt to take place catching phenomenon to the interference of first working piston and seal ring, seal ring is injury-free, guarantee the guide piston free fall and automatically reset better, also guaranteed the wearing and tearing of braking flashboard evenly, break is stable.
