Description

Technical Field

[0001] This disclosure specifically discloses a technology in the field of elevator guide wheel technology, specifically relating to a novel steel belt guide wheel structure. Background Technology

[0002] In a steel belt traction elevator, the traction machine is connected by a steel belt to form a transmission system. The steel belt passes around the guide wheel to form a guiding system. The motor drives the traction wheel to rotate, thereby lifting the elevator platform.

[0003] According to application number 202021033321.9, a novel steel belt guide wheel structure is disclosed, comprising: a guide shaft, steel belt pulleys, shaft retaining rings, ball bearings, and spacers; the number of steel belt pulleys is n, n≥2; the number of ball bearings is 2n; each steel belt pulley has a steel belt groove on its outer surface; each steel belt pulley has two ball bearings installed on its inner ring, located at both ends of the inner ring, and the steel belt pulleys are mounted on the guide shaft via the ball bearings; the number of shaft retaining rings is two, mounted on the guide shaft, located on the outermost sides of the two steel belt pulleys; the number of spacers is n-1, mounted on the guide shaft, and located between adjacent steel belt pulleys.

[0004] Existing steel belt guide wheels use multiple independent guiding structures, but they use simple partitions to separate adjacent guide wheels. These partitions are made of steel or plastic, and friction inevitably occurs during operation, resulting in a harsh sound. In addition, steel belt elevator guide wheels suffer from problems such as easy slippage of the steel belt, unsatisfactory guiding stability, easy wear of the guide wheels, and short service life. Therefore, we propose a new type of steel belt guide wheel structure. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, this application aims to provide a structure that reduces noise and prevents slippage.

[0006] A novel steel belt guide wheel structure includes a guide shaft. Limiting grooves are uniformly formed on the outer wall of the guide shaft, arranged in a linear array. A retaining ring is installed within the inner cavity of each limiting groove. An annular support ring is fixedly connected to the outer ring of each retaining ring. Annular grooves are formed on both the left and right end faces of the support ring. Ball bearings are uniformly installed within the inner cavity of each annular groove. Bearings are installed between adjacent retaining rings, with the ball bearings fitting against the outer ring of the bearing. A steel belt pulley is fitted onto the outer wall of the bearing.

[0007] According to the technical solution provided in the embodiments of this application, the cross-sectional opening length of the annular groove is smaller than the diameter of the annular groove.

[0008] According to the technical solution provided in the embodiments of this application, the upper end face of the steel pulley is fixedly connected to both the left and right sides with limit rings, and the opposite end face of the limit rings is fixedly connected to a rubber pad.

[0010] According to the technical solution provided in the embodiments of this application, the ball bearings are provided in 24 sets, and the ball bearings are matched with the annular groove.

[0011] According to the technical solution provided in the embodiments of this application, a wear-resistant layer is fixedly connected to the surface of the steel pulley.

[0012] In summary, this application discloses a novel steel belt guide wheel structure.

[0013] Beneficial effects:

[0014] 1. Through the support ring, annular groove, and balls, the support ring plays a crucial role in the entire structure. It ensures that the contact between the bearing and the retaining ring is controlled, thereby generating the necessary friction to maintain the stable operation of the system. Specifically, the support ring, through its specific shape and installation position, closely cooperates with the bearing and retaining ring to form a stable support relationship between them. The annular groove is an important structure to ensure the normal rolling of the balls. Its carefully designed shape and size perfectly adapt to the size and movement trajectory of the balls. When the system is running, the balls roll freely within the annular groove. The inner wall of the groove provides precise guidance for the balls, preventing them from shifting or jamming, ensuring continuous and stable rolling, and thus ensuring the smooth operation of the entire system. The contact method between the balls and the outer ring of the bearing is extremely sophisticated. The balls fit tightly against the outer ring of the bearing with appropriate pressure. During operation, this contact method effectively reduces friction. Compared to other possible contact methods, the rolling friction of the balls is far less than that of sliding friction, greatly reducing energy loss. It is precisely because of this low-friction operating state that the harsh noise caused by friction during operation is effectively avoided, enabling the equipment to operate in a quiet and efficient environment.

[0015] 2. In the steel belt drive system, the steel pulley is designed with a series of unique and ingenious structures to achieve efficient and stable transmission performance. The surface of the steel pulley is a carefully designed arc shape, which is matched with a corresponding groove structure. This combination of arc surface and groove greatly increases the actual contact area between the steel belt and the steel pulley. Compared with the traditional planar contact form, the increased contact area can more evenly distribute the pressure generated during transmission, effectively improving the friction between the steel belt and the steel pulley, thereby enhancing the stability and reliability of the transmission. To further ensure the precise operation of the steel belt during transmission, the system is specially equipped with a limiting ring, which works in conjunction with the groove structure. The limiting ring, with its special position and shape design, can effectively constrain the position of the steel belt during operation, while the groove guides the steel belt from another dimension. The two complement each other, effectively preventing the steel belt from shifting or slipping under complex conditions such as high-speed operation or load changes, ensuring that the transmission system is always in a precise and stable operating state.

[0020] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] As mentioned in the background section, existing steel belt guide wheels use multiple independent guide structures, but simple partitions are used to separate adjacent guide wheels. These partitions are made of steel or plastic, and friction inevitably occurs during operation, resulting in a harsh sound. Furthermore, steel belt elevator guide wheels suffer from problems such as easy slippage of the steel belt, unsatisfactory guiding stability, easy wear of the guide wheels, and short service life. This disclosure proposes a structure that reduces noise and prevents slippage.

[0023] Example 1

[0024] Please see Figure 1 A novel steel belt guide wheel structure includes a guide shaft 1. The guide shaft 1 is relatively long, which facilitates the assembly of multiple sets of steel belt guide wheels. Limiting grooves 11 are evenly opened on the outer wall of the guide shaft 1, and the limiting grooves 11 are arranged in a linear array to ensure that the steel belt wheel 4 and the bearing 9 have the same specifications. A retaining ring 2 is installed in the inner cavity of the limiting groove 11. In order to avoid friction between the bearing 9 and the retaining ring 2, an annular support ring 3 is fixedly connected to the outer ring of the retaining ring 2. Annular grooves 8 are opened on both the left and right end faces of the support ring 3. Rolling balls 7 are evenly installed in the inner cavity of the annular grooves 8. The rolling balls 7 fit against the outer ring of the bearing 9, effectively avoiding noise after friction.

[0025] Please see Figure 1 To ensure the normal use of the steel pulley 4, a bearing 9 is installed between adjacent retaining rings 2, and the steel pulley 4 is fitted on the outer wall of the bearing 9.

[0026] Please see Figure 1 To ensure that the outer ring of the bearing can rotate normally, the cross-sectional opening length of the annular groove 8 is designed to be smaller than its own diameter. This design aims to build a reliable constraint mechanism to prevent the balls 7 from falling off the predetermined track during operation. In this way, the balls 7 can be effectively prevented from falling off accidentally during rolling, thereby ensuring the stable operation of the entire bearing system.

[0027] Please see Figure 1 and Figure 2 To effectively prevent the steel belt from shifting, limit rings 6 are securely fixed to both sides of the upper end face of the steel belt pulley 4. The limit rings 6 play a crucial role here, with rubber pads fixedly connected to their opposing inner surfaces. This design aims to avoid direct friction between the steel belt and the limit rings 6. Through the buffering and isolation provided by the rubber pads, the steel belt remains stable during operation, reducing wear caused by friction, thereby extending the service life of the steel belt and ensuring the efficient and stable operation of the entire system.

[0028] Please see Figure 2To effectively prevent slippage of the steel belt during operation, the surface of the steel pulley 4 is specially designed to be arc-shaped. At the same time, grooves 5 are opened in the middle of the steel pulley 4. It is worth mentioning that the connection between the surface of the steel pulley 4 and the grooves 5 is carefully rounded to ensure that the steel belt can transition more smoothly during operation, reduce jamming and wear, and improve the overall transmission efficiency and stability.

[0029] Please see Figure 2 To ensure smooth and stable rotation of the outer ring of bearing 9, the balls 7 are meticulously arranged in 24 groups. This precise number is based on a comprehensive consideration of factors such as the mechanical distribution, load bearing capacity, and speed stability during bearing operation. Simultaneously, the balls 7 are designed to achieve a high degree of matching with the annular groove 8. This matching is not a simple fit, but rather meets strict standards in terms of tolerance control, surface roughness, and geometric accuracy, thus ensuring that the balls 7 can roll smoothly and without obstruction within the annular groove 8. Only when the balls 7 can roll so stably and smoothly can the normal rotation of the outer ring of bearing 9 be further guaranteed during use, avoiding abnormal conditions such as jamming or misalignment caused by poor fit between the balls and the groove or an unreasonable number of balls. This eliminates the possibility of harsh noises during use and maintains low-noise and high-efficiency operation of the equipment.

[0030] Please see Figure 2 Each steel pulley 4 has two sets of bearings 9 installed on both its left and right sides. These bearings 9 are ball bearings, with the rolling elements being spheres that make point contact with the raceway. This results in relatively low frictional resistance during operation, effectively reducing energy loss and improving mechanical efficiency. This makes ball bearings widely used in various mechanical equipment, reducing power consumption and saving energy. Ball bearings can operate stably at high speeds, and the relatively small sliding between their rolling elements and raceways allows them to withstand high centrifugal forces.

[0031] Please see Figure 1 and Figure 2 The retaining ring 2 is designed with a C-shaped structure and can be made of spring steel. This structure can perfectly fit the limiting groove 11, ensuring a precise fit between the two and effectively performing its function.

[0032] Example 2

[0033] Please see Figure 2 To effectively extend the service life of the steel belt guide wheel, a wear-resistant layer 10 is firmly attached to the surface of the steel belt pulley 4. This wear-resistant layer can significantly reduce the coefficient of friction, greatly improve the wear resistance, and thus effectively extend the overall service life of the steel belt guide wheel.

[0034] Working Principle: In practical applications, the steel belt is tightly fitted onto the outer wall of the steel pulley 4, playing a crucial transmission role. Notably, the upper inner wall of the steel belt features an integrally formed raised strip. This ingeniously designed strip perfectly matches the groove 5, allowing for precise installation within the groove's inner cavity. Simultaneously, the limiting ring 6 plays a vital role, fundamentally preventing slippage of the steel belt during operation by restricting the position of its two end faces, thus ensuring the stability and reliability of the transmission.

[0035] The innovative design of the arc-shaped steel pulley 4 and the matching groove 5 offers significant advantages. Under the same width conditions, this design effectively increases the contact area between the steel pulley 4 and the steel belt. This increased contact area directly leads to improved friction, thereby significantly reducing energy consumption and improving energy efficiency during transmission. Furthermore, the wear-resistant layer 10 covering the surface of the steel pulley 4 greatly enhances its overall wear resistance. This not only reduces frequent replacements due to frictional wear but also significantly extends the service life of the steel pulley 4, lowering maintenance costs and downtime.

[0036] From a structural design perspective, the ball bearings 7 on both ends of the support ring 3 are equally indispensable. On one hand, the ball bearings 7 effectively restrict the lateral movement of the bearing 9, indirectly stabilizing the position of the steel pulley 4 by precisely controlling its position, thus ensuring the structural stability of the entire transmission system. On the other hand, the ball bearings 7 significantly reduce the friction between the retaining ring 2 and the bearing 9, allowing the outer ring of the bearing 9 to rotate smoothly and normally. This effectively avoids the harsh noise generated by friction during equipment operation, creating a quieter and more comfortable working environment and improving the overall operational quality of the equipment.

[0037] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
