Description

Technical Field

[0001] This utility model relates to the field of traction machines, and in particular to a double-support structure rewinding traction machine. Background Technology

[0002] Traditional traction machines have certain limitations in structural design. For example, their layout is not compact enough, resulting in a large overall size and occupying a lot of space, making them unsuitable for installation and use in space-constrained environments. Furthermore, the main shaft support structure of traditional traction machines is often relatively simple, failing to effectively distribute axial and radial loads. This makes the main shaft and related components susceptible to significant stress, leading to structural instability and accelerated component wear over long-term operation, thus affecting the equipment's lifespan and operational reliability. In addition, the lack of proper lubrication for the bearings in traction machines results in a high coefficient of friction, severe wear, and high energy consumption during operation, increasing maintenance costs and complexity. Utility Model Content

[0003] The purpose of this invention is to provide a double-support structure rewinding traction machine that can solve the above-mentioned problems.

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

[0005] A double-supported rewinding traction machine includes a base, a main shaft, a traction sheave, a wound stator core, a rotor assembly, and a brake. The base has a first chamber and a second chamber communicating with the first chamber. The rotor assembly is disposed within the first and second chambers and connected to the main shaft passing through the base. A brake is located on one side of the main shaft. The connection between the rotor assembly and the main shaft is located in the middle of the main shaft and within the first chamber. The traction sheave is sleeved on the rotor assembly and located within the first chamber. The wound stator core is located within the second chamber and is disposed inside the rotor assembly. A first bearing and a second bearing are respectively provided on both sides of the connection between the main shaft and the rotor assembly. An end cap is provided on the first bearing and connected to the base. The second bearing is located between the base and the main shaft.

[0006] Preferably, the two ends of the main shaft are respectively provided with a first step portion and a second step portion, the diameter of the first step portion and the second step portion is smaller than the middle portion of the main shaft, and the first bearing and the second bearing are respectively disposed at the positions of the first step portion and the second step portion.

[0007] Preferably, an encoder is provided at one end of the main shaft, an encoder bearing end cover is provided on the side of the first bearing near the encoder, and a first bearing inner cover is provided on the other side of the first bearing. Both the encoder bearing end cover and the first bearing inner cover are connected to the end cover.

[0008] Preferably, the second bearing has an outer cover on the side near the brake and an inner cover on the other side, both the outer cover and the inner cover being connected to the base.

[0009] Preferably, the first bearing inner cover, the second bearing inner cover, the bearing outer cover, and the encoder bearing end cover are all provided with oil injection holes for lubricating the first bearing and the second bearing.

[0010] Preferably, the first bearing and the second bearing are self-aligning roller bearings.

[0011] Preferably, the rotor is connected to the turning gear.

[0012] The beneficial effects of this utility model are as follows: The spatial layout of this utility model makes the internal structure of the equipment more compact, fully utilizing the internal space of the base, effectively reducing the overall volume of the equipment, facilitating installation and use in space-constrained environments, and improving the applicability of the equipment. By setting two bearings on both sides of the main shaft to form a double-support structure, axial and radial loads can be effectively distributed, avoiding excessive stress on the main shaft and related components in traditional single-support structures. This greatly improves the stability of the structure, reduces component wear and deformation caused by concentrated loads, thereby extending the service life of the equipment and reducing the frequency and cost of maintenance. Lubrication of the first and second bearings reduces the coefficient of friction, decreases wear and energy consumption, improves the operating efficiency of the equipment, and makes lubrication more convenient, reducing the difficulty and cost of equipment maintenance and ensuring long-term stable operation of the equipment.

[0019] like Figures 1 to 3 As shown, this utility model provides a double-support structure rewinding traction machine, which includes a base 1, a main shaft 2, a traction sheave 3, a stator core 4 with windings, a rotor assembly 5, and a brake 6. The base 1 has a first chamber 7 and a second chamber 8, with the second chamber 8 located on one side of the first chamber 7 and communicating with it.

The connection between the rotor assembly 5 and the main shaft 2 is located in the middle of the main shaft 2, and this connection is located within the first chamber 7. The traction sheave 3 is fitted onto the rotor assembly 5 and is located within the first chamber 7. This spatial layout makes the internal structure of the equipment more compact, fully utilizes the internal space of the base 1, and reduces the overall volume of the equipment. The wound stator core 4 is located within the second chamber 8 and is also positioned inside the rotor assembly 5. A first bearing 10 and a second bearing 11 are respectively installed on both sides of the connection between the main shaft 2 and the rotor assembly 5. Both bearings are self-aligning roller bearings. An end cover 20 is installed on the first bearing 10, and the end cover 20 is connected to the machine base 1. The second bearing 11 is positioned between the machine base 1 and the main shaft 2. The first bearing 10 and the second bearing 11 installed on both sides of the main shaft 2 form a double-support structure, effectively distributing axial and radial loads, improving structural stability, and extending the service life of the equipment.

[0020] Furthermore, a first step portion 12 and a second step portion 13 are respectively provided at both ends of the main shaft 2.

The first bearing 10 and the second bearing 11 are respectively located at the positions of the first step portion 12 and the second step portion 13 to position the two bearings.

[0021] Furthermore, an encoder bearing end cover 14 is provided on the side of the first bearing 10 near the encoder 9, and a first bearing inner cover 15 is provided on the other side of the first bearing 10.

The first bearing inner cover 15 and the second bearing inner cover 19 are both provided with oil passages 18 communicating with the oil filling holes 17. By lubricating the first bearing 10 and the second bearing 12, the coefficient of friction between machine parts can be greatly reduced, wear and energy consumption can be reduced, and lubrication can be made more convenient.

[0022] The spatial layout of this invention makes the internal structure of the equipment more compact, making full use of the internal space of the base 1, effectively reducing the overall size of the equipment, facilitating installation and use in space-constrained environments, and improving the applicability of the equipment. By setting two bearings on both sides of the main shaft 2 to form a double-support structure, the axial and radial loads can be effectively distributed, avoiding the excessive stress on the main shaft and related components in the traditional single-support structure, greatly improving the stability of the structure, reducing component wear and deformation caused by load concentration, thereby extending the service life of the equipment and reducing the frequency and cost of maintenance.
