Description

Technical Field

[0001] This invention relates to the field of mobile shelving technology, and in particular to a low-loss transmission device. Background Technology

[0002] Currently, the transmission relationship of mobile shelving is usually as follows: the main shaft gear drives the driven shaft gear through the chain, which in turn drives the driven shaft, thereby rotating the rollers fixed on the driven shaft and completing the operation of the equipment.

[0003] However, the main drawbacks of the existing roller action device structure and corresponding transmission method are that the transmission relationship is complex, the cumulative error increases, the transmission structure is unreasonable, and after multiple transmission components are assembled through high-temperature welding, drilling and other processes, the relevant components are prone to deformation, resulting in misalignment, which seriously affects the transmission efficiency and the running quality of the mobile shelving, causing the operation to be unsmooth, producing vibration, loud noise, and lack of coordination and synchronization between the front and rear ends, and poor sealing effect of the shelving. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems of the above and / or existing mobile devices, the present invention is proposed.

[0006] Therefore, the problem to be solved by this invention is how to address the complex driving and walking transmission relationship, the increase in accumulated errors, the unreasonable transmission structure, and the fact that after multiple transmission components are assembled through high-temperature welding, drilling and other processes, the components are prone to deformation, resulting in non-concentricity, which seriously affects the running quality of the mobile shelving, causing the operation to be unsmooth, shaking, noisy, asynchronous at the front and rear ends, and poor sealing effect of the shelving.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a low-loss transmission device, including a roller and a transmission gear, and also including a corresponding bearing, wherein the roller and the transmission gear are fixedly mounted on the bearing, forming an integral part of the roller, the transmission gear and the bearing.

[0008] The transmission gear and roller are embedded and fixed on the outer peripheral wall of the bearing.

[0009] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are:

[0010] This invention integrates rollers, transmission gears, and bearings into a single unit, changing the traditional structure of mobile shelving base drive transmission. The power output is more direct, the output torque is greater, and it effectively avoids the misalignment problem caused by the assembly deformation of each transmission component. This ensures the stability, reliability, low loss, and high efficiency of the integrated transmission gears, rollers, and bearings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0022] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention, which provides a low-loss transmission device, including a support shaft (i.e., a traveling shaft) 4, rollers 1, bearings 2, and transmission gears (i.e., traveling wheels) 3. The rollers, transmission gears, and bearings are integrated into one unit.

[0023] Its support shaft 4 is connected to the corresponding position of the mobile shelving base 5, and the transmission gear 3 and roller 1 are arranged side by side on the bearing 2. The bearing 2 is installed on the support shaft through its hole, and the transmission gear 3, roller 1 and bearing 2 are arranged on the same axis and coaxial with the support shaft.

[0024] In this example, the transmission gear 3 and roller 1 can be precision-mounted and fixedly connected to the outer peripheral wall of the bearing 2. That is, the roller and transmission gear are simultaneously fixedly mounted on the peripheral wall of the bearing, forming an integral part with the bearing. Precision mounting uses higher machining accuracy and manufacturing equipment precision to achieve better concentricity accuracy for the roller 1, bearing 2, and transmission gear 3.

[0025] In this embodiment, the connection structure and connection method between the support shaft 4 and the bearing 2 are similar to those of the existing support shaft and bearing connection structure and connection method.

[0026] When using this low-loss transmission device: the support shafts can be fixedly connected to the positions of the rollers or walking wheels on the base frame 5 of the mobile shelving unit. This connection can be similar to the existing walking wheel configuration. Each bearing of this low-loss transmission device is then sleeved and connected to its corresponding support shaft. The transmission gear 3 is connected to the corresponding drive gear 8 on the drive shaft 7 of the mobile shelving unit via a chain 6. When the drive shaft and its drive gear rotate under driving force, they drive the transmission gear 3 and rollers 1 to rotate simultaneously around the support shaft via bearings 2. The rollers roll on the ground or on guide rails laid on the ground, thereby driving the mobile shelving unit to move.

[0027] The distance between the transmission gears and rollers on the support shaft in this invention can be determined based on the distance between the corresponding drive gears 8 on the drive shaft 7.

[0028] Example 2. In this example, the transmission gear and roller can be fixedly connected to the outer peripheral wall of the bearing via a keyway connection device. The keyway connection device is similar to the corresponding keyway connection structure and corresponding connection assembly method in the prior art.

[0029] Example 3. (As shown) Figure 5 and 6 As shown, a positioning ring 9 is embedded in the support shaft. The positioning ring limits the bearing at its opposite ends to ensure that the bearing is positioned at the appropriate mounting point on the support shaft. Furthermore, the outer diameters at both ends of the support shaft are narrowed for ease of assembly. The remaining structure and corresponding transmission operation methods in this example are similar to those in the above embodiments.

[0030] The above-described embodiments are merely preferred embodiments of the present invention and not limitations. Those skilled in the art should understand that the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention without departing from the technical solution and inventive concept of the present invention should be covered within the scope of protection of the present invention.
