Description

Technical Field

[0001] The invention relates to a brake, in particular to a brake with a silencer. Background Art

[0002] The brake is a device that has the function of slowing down, stopping or keeping moving parts or moving machinery in a stopped state. In order to reduce the braking torque and structural size, the brake is usually installed on the high-speed shaft of the equipment. However, large equipment with higher safety requirements, such as mine hoists and elevators, should be installed on the low-speed shaft close to the working part of the equipment.

[0003] The conventional brake has a brake damping pad placed at each of the four corners of the armature assembly. During use, the damping pad will wear out due to multiple opening / closing operations, causing contact between the armature assembly and the armature assembly, which increases the noise. Therefore, we have made an improvement and proposed a brake with a silencer. Summary of the invention

[0007] As a preferred technical solution of the present invention, placement grooves are provided at four corners of the armature assembly on one side close to the armature assembly, and shock-absorbing pads are provided in the placement grooves.

[0008] As a preferred technical solution of the present invention, the shock-absorbing pad is an elastic rubber pad, and one end of the shock-absorbing pad protrudes and the placement groove is placed outside it.

[0009] As a preferred technical solution of the present invention, the silencer includes a threaded rod and a nut. The threaded rod is placed in a slot extending through the armature assembly. The nut is cooperatively sleeved on the outside of the threaded rod and is fixedly connected to the armature assembly.

[0010] As a preferred technical solution of the present invention, one end of the threaded rod passes through a nut and is placed outside the armature assembly, and the other end of the threaded rod is rotatably connected to a push block through a bearing.

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] Example: Figure 1 and Figure 2As shown, a brake with a silencer device of the present invention comprises an armature assembly 1, an armature assembly 5 and an automatic assembly 6, wherein the armature assembly 5 is movably arranged on one side of the armature assembly 1, and the automatic assembly 6 is fixedly arranged in the middle of the armature assembly 5 on a side away from the armature assembly 1, and an opening mechanism 2 is arranged in the middle of the armature assembly 1, and one end of the opening mechanism 2 passes through the armature assembly 5 and the automatic assembly 6 in sequence and is placed in the automatic assembly 6, a micro switch assembly 4 is arranged on the top of the armature assembly 1, and silencers 3 are symmetrically arranged on both ends of the armature assembly 1 on a side away from the armature assembly 5.

[0020] Among them, the armature assembly 1 is provided with placement grooves 8 at the four corners on the side close to the armature assembly 5, and a shock-absorbing pad 7 is arranged in the placement groove 8. The shock-absorbing pad 7 is an elastic rubber pad, and one end of the shock-absorbing pad 7 protrudes and is placed outside the placement groove 8. During the closing process, the armature assembly 5 moves along the side close to the armature assembly 1. The shock-absorbing pad 7 can reduce the collision between the armature assembly 5 and the armature assembly 1, thereby playing a certain buffering role.

[0021] The silencer 3 includes a threaded rod 301 and a nut 302. The threaded rod 301 is placed in a slot that is penetrated through the armature assembly 1. The nut 302 is matched and sleeved on the outside of the threaded rod 301. The nut 302 is fixedly connected to the armature assembly 1. One end of the threaded rod 301 passes through the nut 302 and is placed outside the armature assembly 1. The other end of the threaded rod 301 is rotatably connected to a push block 303 through a bearing. Both sides of the push block 303 are fixedly provided with limit blocks 9. The two limit blocks 9 are respectively placed in the slots. The limit grooves are opened on both sides, and a flexible rubber pad is fixedly provided on one end of the push block 303 close to the armature assembly 5. A screwing head is fixedly provided on one end of the threaded rod 301 placed outside the armature assembly 1. A non-slip rubber sleeve is provided on the outside of the screwing head. The screwing sleeve is turned to drive the threaded rod 301 to rotate. The threaded rod 301 moves and pushes the push block 303 to move along the limit groove. The movement of the push block 303 can push the armature assembly 5, so as to push the armature assembly 5 and the armature assembly 1 out a certain distance.

[0022] During operation, when the brake noise increases during the gate opening / or closing process by the maintenance personnel, the inspection personnel can simultaneously turn the two screw sleeves in the same direction to drive the two threaded rods 301 to rotate simultaneously, and the threaded rod 301 moves to push the push block 303 to move forward along the limit groove, and the armature assembly 1 and the armature assembly 5 are pushed out a certain distance through the push block 303. In this way, the contact and collision area between the armature assembly 1 and the armature assembly 5 will be reduced during the gate opening or closing process, which can reduce a certain amount of noise.
