Description

Technical Field

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

[0002] In the elevator industry, the traction machine, as a core drive component, directly affects the elevator's operational stability, safety, and overall service life. Traditional machine-room-less traction machines have many limitations in design and structure, making it difficult to meet the demands of modern elevators that are becoming smaller, more efficient, and more stable.

[0003] On the one hand, the traditional traction machine's structural layout is not compact enough, and the installation method of each component results in a large overall size, occupying a significant amount of elevator shaft space and limiting the flexibility and applicability of elevator installation. On the other hand, in terms of stress, the components of a traditional traction machine experience uneven stress during operation, making them prone to significant deformation. This deformation not only affects the performance and lifespan of the traction machine itself, causing adverse effects, but also leads to decreased measurement accuracy and instability in these components, ultimately impacting the overall operational quality of the elevator. Furthermore, the encoder installation method of traditional traction machines often occupies a large space, hindering the design of a slim traction machine, and requires the disassembly of many components during maintenance and replacement, making the operation cumbersome. Therefore, how to design a dual-support, machine room-less, ultra-thin traction machine is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a dual-support, machine room-less, ultra-thin traction machine that can solve or partially solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A dual-support, roomless, ultra-thin traction machine includes a base, a stator, a rotor, a traction sheave, and a rotating shaft. The stator, rotor, and traction sheave are all disposed within a cavity in the base. The rotor is disposed outside the stator, and the traction sheave is sleeved on the rotor. The rotor is connected to the rotating shaft. A support seat connected to the base is disposed on one side of the base. The rotating shaft is mounted on the support seat and the base via a first bearing and a second bearing. An end cover connected to the support seat is disposed at the center of the support seat. An encoder is disposed at the center of the end cover and is connected to the end of the rotating shaft.

[0006] Preferably, both the front and rear ends of the rotating shaft are provided with stepped portions, the rotor is disposed at the stepped portion at the front end of the rotating shaft, the second bearing is disposed at the stepped portion at the rear end of the rotating shaft, the first bearing is located between the support base and the rotor, and the second bearing is disposed between the base and the rotating shaft.

[0007] Preferably, the center of the support base is recessed into the base to form a recessed area, and the encoder is located within the recessed area.

[0008] Preferably, the support base is provided with a plurality of support base stops protruding from the support base, the support base stops cooperating with the machine base, both the support base and the machine base are provided with a plurality of corresponding fixing holes, and the support base and the machine base are connected by bolts.

[0009] Preferably, the encoder's code disk is connected to the end of the rotating shaft, and the encoder's read head is disposed on the end cover.

[0010] Preferably, the end cap is provided with an end cap stop protruding from the end cap, and the end cap stop is engaged with a portion of the support seat near the first bearing.

[0011] The beneficial effects of this utility model are as follows: The overall structure of the dual-support, machine room-less ultra-thin traction machine of this utility model is more stable and compact. By hiding the stator, rotor, and traction sheave in the cavity of the machine base, a nearly closed cavity structure is formed, making the layout between the components more reasonable, effectively reducing the overall size of the machine, saving space, and improving the flexibility and applicability of elevator installation. The two ends of the rotating shaft are supported by the first and second bearings, and the support seat stops fit with the machine base to ensure high concentricity of the two bearing chambers, suppressing rotor eccentric swing, reducing vibration noise, and extending bearing life. The encoder is embedded in the recessed area of ​​the support seat and does not protrude from the surface of the support seat, which not only effectively protects the encoder but also makes the overall axial dimension of the encoder more compact, further reducing the size of the traction machine and the space required for installation, improving space utilization, and achieving ultra-thinness and miniaturization.

Detailed Implementation

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] 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.

[0015] like Figures 1 to 4 As shown, a dual-support, roomless, ultra-thin traction machine includes a base 1, a stator 2, a rotor 3, a traction sheave 4, and a rotating shaft 5. The stator 2, rotor 3, and traction sheave 4 are all housed within a cavity 6 in the base 1. The rotor 3 is positioned outside the stator 2, and the traction sheave 4 is fitted onto the rotor 3. The rotor 3 is connected to the rotating shaft 5. A support 7 connected to the base 1 is located on one side of the base 1. The rotating shaft 5 is mounted on the support 7 and the base 1 via a first bearing 8 and a second bearing 9. Stepped portions 51 are provided at both the front and rear ends of the rotating shaft 5. The rotor 3 is positioned at the stepped portion 51 at the front end of the rotating shaft 5, and the second bearing 9 is positioned at the stepped portion 51 at the rear end of the rotating shaft 5. The first bearing 8 is located between the support 7 and the rotor 3, and the second bearing 9 is located between the base 1 and the rotating shaft 5. An end cap 10 connected to the support 7 is located at the center of the support 7, and an encoder 11 is located at the center of the end cap 10 and connected to the end of the rotating shaft 5. The overall structure of this utility model is more stable and compact. The whole machine is almost a closed cavity. The stator 2, rotor 3 and traction wheel 4 are all hidden in the cavity 6 of the base 1. In the working state, the force is uniform and the deformation is small, which reduces the impact of the main unit's load deformation on the other components installed on the traction machine.

[0016] Furthermore, the center of the support base 7 is recessed inwards towards the base 1 to form a recessed area. The encoder 11 is located within the recessed area and does not protrude from the support base 7, which effectively protects the encoder 11. At the same time, the traction sheave 4 is also protected within the support base 7. The encoder 10 has a compact overall axial dimension, which helps to reduce the size of the traction machine and the space required for installation.

[0017] The support base 7 is provided with several support base stops 71 protruding from the support base 7. The support base stops 71 cooperate with the machine base 1. Both the support base 7 and the machine base 1 are provided with several fixing holes 12. The support base 7 and the machine base 1 are connected by bolts, which can ensure the concentricity of the front and rear bearing chambers and ensure that the first bearing 8 and the second bearing 9 are always in a stable stress state. At the same time, the machining dimensions of the main components are almost all circular, which saves machining time.

[0018] The code disk 111 of the encoder 11 is connected to the end of the rotating shaft 5, and the encoder code disk 111 rotates with the rotating shaft 5. The read head 112 of the encoder 11 is mounted on the end cover 10. The end cover 10 is provided with an end cover stop 101 protruding from the end cover 10. The end cover stop 101 is engaged with the support seat 7 near the first bearing 8 to reduce the radial misalignment between the encoder code disk 111 and the read head 112. When replacing the encoder, it is not necessary to remove the support seat; only the end cover 11 and the encoder read head 102 need to be removed. Installing and removing the encoder 10 is relatively convenient.
