Description

Technical Field

[0001] This utility model relates to the field of traction machines, and in particular to a traction machine with a disc brake and anti-friction disc structure. Background Technology

[0002] Traditional traction machine shaft brakes involve installing a brake disc at the end of the traction machine shaft. During rotation, the traction machine moves back and forth between the machine base end cover and the brake armature due to centrifugal force. This causes the brake disc surface to rub against the machine base end cover surface and the brake armature surface, generating noise and affecting the performance of the traction machine. Utility Model Content

[0003] The purpose of this invention is to provide a disc brake anti-friction disc structure traction machine that can solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A disc brake anti-friction disc structure traction machine includes a base, a main shaft, a traction sheave, a stator winding core, a rotor, a first bearing, a second bearing, and a brake. The main shaft passes through the base and is connected to the traction sheave and the brake, which are respectively disposed on both sides of the base. The stator winding core and the rotor are both disposed within the base, with the rotor disposed outside the stator winding core and connected to the main shaft. The first bearing and the second bearing are disposed between the base and the main shaft. The base is connected to a base end cover, and the brake is disposed on one side of the base end cover. The main shaft is provided with a first damping pad and a second damping pad, which are respectively disposed on both sides of the brake disc of the brake. An adjusting pressure plate is disposed at the end of the main shaft near the second damping pad.

Detailed Implementation

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] In the description of this utility model, it should be noted that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 2 As shown, this utility model provides a disc brake anti-friction disc structure traction machine, which includes a base 1, a main shaft 2, a traction sheave 3, a stator winding core 4, a rotor 5, a first bearing 6, a second bearing 7, and a brake 8. The main shaft 2 passes through the base 1 and connects to the traction sheave 3 and the brake 8, which are respectively located on both sides of the base 1. The stator winding core 4 and the rotor 5 are both located inside the base 1, with the rotor 5 located outside the stator winding core 4 and connected to the main shaft 2. The first bearing 6 and the second bearing 7 are located between the base 1 and the main shaft 2. The first bearing 6 is located on the side closer to the traction sheave 3, and the second bearing 7 is located on the side closer to the rotor 5. The first bearing 6 and the second bearing 7 are a self-aligning bearing and a deep groove ball bearing, respectively. An encoder 10 is provided at one end of the main shaft 2. A base end cover 9 is connected to the side of the base 1 near the brake 8.

[0021] The main shaft 2 is provided with a first damping pad 11 and a second damping pad 12, which are respectively located on both sides of the brake disc 81 of the brake 8. An adjusting pressure plate 13 is provided on the end of the main shaft 2 near the second damping pad 12. The main shaft 2 near the brake 8 has a first step portion 21 and a second step portion 22. The first damping pad 11 is located at the first step portion 21, and the adjusting pressure plate 13 is sleeved on the main shaft 2 and located at the second step portion 22.

[0022] Furthermore, the first damping pad 11 includes an annular damping pad body 111 and an annular protrusion 112 integrally connected to and protruding from the damping pad body 111. The annular protrusion 112 is located on the side near the brake disc 81, and a gap 113 is provided between the annular protrusion 112 and the main shaft 2. By providing the first damping pad 11, a gap X is generated between the machine base end cover 9 and the brake disc 81, which can reduce the noise generated by the friction between the brake surface of the brake disc 8 and the machine base end cover 9. The hardness of the first damping pad 11 of this invention is lower than that of the second damping pad 12. When the brake 8 compresses the first damping pad 11, the annular protrusion 112 and the gap 113 can weaken the influence of the first damping pad 11 on the braking force.

[0023] The adjusting pressure plate 13 includes a sleeve 131 fitted onto the main shaft 2 and an outer plate 132 extending outward from the outer edge of the sleeve 131. The sleeve 131 is threadedly connected to the circumferential surface of the second step portion 22, and the outer plate 131 extends out of the second step portion 22 and abuts against the second damping pad 12. Both the first damping pad 11 and the second damping pad 12 are made of rubber. The main shaft 2 is connected to the brake and the rotor 5 via splines.

[0024] The working principle of this utility model is as follows: A first damping pad 11 is provided between the first step portion 21 of the main shaft 2 and the inner side of the brake disc 81, and a second damping pad 12 is provided between the outer sides of the brake disc 81. The gap X between the brake disc 81 and the machine base end cover 9, and the gap Y between the brake disc 81 and the armature of the brake 8 are controlled by the threaded locking of the adjusting pressure plate 13 on the second step portion 22.

[0025] The first damping pad 11 of this invention has a lower hardness than the second damping pad 12, which weakens its influence on braking force. The second damping pad 12 has a slightly higher hardness, which facilitates the adjustment of the pressure plate 13. By adjusting the pressure plate 13, the second damping pad 12 deforms and generates elasticity, fixing the brake disc 81 on the spline. When the brake 8 is engaged, the armature 82 of the brake 8 presses the brake disc 81 against the end face. When the brake 8 is released, the armature 82 releases the brake disc 81. At the same time, the first damping pad 11, after being compressed and reset, exerts a force on the brake disc 81 in the direction of the encoder 10. Simultaneously, the second damping pad 11 exerts a reverse force on the brake disc, fixing the brake disc 81 on the main shaft 2. Gap X and gap Y are simultaneously generated between the brake disc 81 and the end cover 9 of the machine base, and between the brake disc 81 and the armature 82 of the brake 8, which prevents the brake disc 81 from rubbing against the end cover 9 of the machine base or the surface of the armature 82 of the brake 8.

[0026] This invention provides a first damping pad 11 and a second damping pad 12 on both sides of the brake disc 81. It also limits the position of the brake disc 81 on the main shaft 2 by adjusting the pressure plate 13. The elasticity of the first damping pad 11 and the second damping pad 12 allows the brake 8 to reset during operation, which greatly reduces the noise generated by friction between the brake disc 81 and the machine base end cover 9, and between the brake disc 81 and the armature 82. Moreover, it is economical in cost and can be widely used in products with the same structure.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
