Abstract
A kind of drum brake brake shoe damping device, comprise brake arm, brake shoe, brake shoe is arranged on brake arm, brake shoe can rotate freely on brake arm, the cross-under of brake shoe screw thread has adjustment screw rod, it is characterized in that the adjustment screw end head place between brake arm, brake shoe is disposed with spring bearer plate, holddown spring, goes directly spring bearer plate in the termination of adjustment screw rod.Compared with the prior art the utility model, has and saves time, safe and reliable, can facilitate the advantage of the cushion effect between adjustable brake watt and brake arm.
Description
Technical field
The utility model relates to a kind of hoist machine drum brake brake shoe damping device.
Background technique
Drum brake hoist machine adopts lever principle due to the braking principle of drum brake, has the advantages that the large brake clearance of break actuating length is little.When brake shoe braking is after Brake drum, because brake arm and brake shoe are Spielpassung, brake arm is after brake shoe stops action, still a bit of operating distance is had, if between brake shoe and brake arm without any cushioning effect, so when brake arm and brake shoe impact, very large impact sound can be produced.Current Application comparison widely a kind of brake shoe damping device is that use one block buffering glue is arranged between brake arm and brake shoe, and reaction force when being compressed by buffering adhesive is to reach cushioning effect.But due to the existence of casting, machining tolerance, distance tolerance between brake arm and brake shoe is very large, so that this buffering method also exists very large deficiency, or buffering adhesive decrement is little cannot reach cushioning effect, or buffering adhesive decrement large installation brake shoe is very difficult.
Summary of the invention
The utility model object is just to provide one and saves time, safe and reliable, can facilitate the drum brake brake shoe damping device of the cushion effect between adjustable brake watt and brake arm.
The utility model object is achieved in that and comprises brake arm, brake shoe, brake shoe is arranged on brake arm, brake shoe can rotate freely on brake arm, the cross-under of brake shoe screw thread has adjustment screw rod, its specialization is that the adjustment screw end head place between brake arm, brake shoe is disposed with spring bearer plate, holddown spring, goes directly spring bearer plate in the termination of adjustment screw rod.
By adjustment screw rod, can adjust active force between brake shoe and brake arm to reach best cushioning effect, adopt holddown spring, the distance tolerance that can effectively adapt between brake arm and brake shoe is very large, to ensure enough cushioning effects.
Here, inside brake arm, corresponding spring bearer plate, holddown spring place are provided with counterbore, and spring bearer plate, holddown spring are arranged in counterbore.
Compared with the prior art the utility model, has and saves time, safe and reliable, can facilitate the advantage of the cushion effect between adjustable brake watt and brake arm.
accompanying drawing illustrates:
Fig. 1 is structural drawing of the present utility model.
In Fig. 1, sequence number illustrates: brake arm 1, brake shoe 2, holddown spring 3, spring bearer plate 4, adjustment screw rod 5, locking nut 6, counterbore 7.
embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in Figure 1, the utility model comprises brake arm 1, brake shoe 2, brake shoe 2 is arranged on brake arm 1, brake shoe can rotate freely on brake arm 1, the cross-under of brake shoe 2 screw thread has adjustment screw rod 5, adjustment screw rod 5 outside brake arm 1 is provided with locking nut 6, and its specialization is that adjustment screw rod 5 end between brake arm 1, brake shoe 2 is disposed with spring bearer plate 4, holddown spring 3, goes directly spring bearer plate 4 in the termination of adjustment screw rod 5.
Inside brake arm 1, corresponding spring bearer plate 4, holddown spring 3 place are provided with counterbore 7, and spring bearer plate 4, holddown spring 3 are arranged in counterbore 7.
