Abstract
Description
Technical Field
[0001] This utility model relates to the field of chain drive technology, and more specifically to a guide wheel chain and transmission device. Background Technology
[0002] Drive chains are a widely used mechanical transmission component. They consist of a chain and driving and driven sprockets. The sprockets have specially shaped teeth, and motion and power are transmitted by the meshing of the sprocket teeth with the chain links.
[0003] Drive chains are used for power transmission in the mechanical field. They are required to have low frictional resistance during transmission, which helps to reduce chain wear and improve efficiency.
[0004] Drive chains are widely used, but often they accumulate dust, dirt, or other debris. Once this debris gets into the bushings and pins inside the chain, it gradually jams the bushings and pins, which were originally moving relatively freely. The bushings also gradually become blocked from the outer chain plates on both sides. This increases friction between the bushings and pins, as well as between the bushings and the outer chain plates on both sides, making the entire chain less flexible and reducing its efficiency. In addition, traditional drive chains are prone to wear, inconvenient to adjust their installation position, and difficult to maintain. Summary of the Invention

Detailed Implementation
[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0019] In the description of this application, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application. In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0021] A type of guide wheel chain, such as Figure 1-6As shown, it includes: multiple link units 100 connected end to end, the multiple link units 100 links forming a ring-shaped guide wheel chain for transmission. Figure 1 and Figure 2 Only five link units 100 are shown in the image, while the number of link units 100 in the entire guide wheel chain is set according to actual needs.
[0022] Adjacent chain link units 100 are connected by a hollow sleeve 200 and a roller 300, with the roller 300 sleeved outside the hollow sleeve 200; The chain link unit 100 includes two symmetrically distributed chain plates 110. The chain plates 110 are made of high-hardness metal and have properties such as corrosion resistance and wear resistance. The front and rear ends of the chain plates 110 are provided with shaft holes, and the hollow sleeve 200 is installed by passing through the shaft holes of the chain plates 110. Specifically, the rear ends of the two chain plates 110 of the previous link unit 100 are superimposed on the front ends of the two chain plates 110 of the next link unit 100, and then a hollow sleeve 200 is installed through the shaft holes of the four chain plates 110; the roller 300 is located between the two chain plates 110, and the link unit 100 rotates around the hollow sleeve 200 as an axis. Here, the rotation of the link unit 100 around the hollow sleeve 200 is to guide the wheel chain to rotate. During the rotation, two adjacent link units 100 will swing relative to each other at a certain angle to realize the transmission and transportation of the guide wheel chain.
[0023] Optionally, the hollow sleeve 200 can be made into a hollow pin with the diameters at both ends larger than the diameter of the shaft hole, so as to prevent the hollow sleeve 200 from detaching after installation; Optionally, limiting components, such as limiting nuts or limiting clamps, can be added to both ends of the hollow sleeve 200 to prevent it from coming off. A guide wheel frame 120 is provided on the chain plate 110 on one side of a chain link unit 100. The guide wheel frame 120 is equipped with a bearing 130, which plays an auxiliary role in operation.
[0024] In one embodiment, roller 300 rotates about axis L1; bearing 130 rotates about axis L2; axis L1 and axis L2 are perpendicular to each other; like Figure 1 As shown, axis L1 is set horizontally, while axis L2 is set perpendicular to the reading surface; Appendix Figure 2 As mentioned above, axis L2 is set horizontally, while axis L1 is set perpendicular to the reading surface.
[0025] Furthermore, on a chain plate 110, there is a connecting line H1 between the shaft holes at the front and rear ends, and a perpendicular line H2 is perpendicular to the connecting line H1. The guide wheel frame 120 is located on the perpendicular line H2, so that the force in a chain link unit 100 is stable.
[0026] Furthermore, the middle portions of both sides of the chain plate 110 are recessed towards each other; here, "both sides" refers to... Figure 2 The left and right sides shown form a notch 111 for mounting the guide wheel frame 120, reducing the overall width of the chain plate 110 and the guide wheel frame 120; as shown Figure 6 As shown, width refers to Figure 6 The horizontal direction in the middle.
[0027] A roller 121 is provided on the guide wheel frame 120, and a bearing 130 is installed on each side of the corresponding chain plate 110. Figure 6 As shown, a pair of bearings are supported within the track bracket 400 to achieve smooth transmission of the guide wheel chain.
[0028] In one embodiment, it further includes: a track support 400, with the link unit 100 located within the track support 400. Specifically, as... Figure 6 As shown, the track support 400 has a longitudinal cross-section with a cross shape of "+", wherein the upper end of the cross shape of the track support 400 passes through the upper end of the track support 400 to form a groove inlet 411.
[0029] like Figure 3 As shown, the mounting groove 410 extends through both ends of the track bracket 400 along its length. After the guide wheel chain is installed in the track bracket 400, the bearing 130 is supported in the mounting groove 410.
[0030] A guide wheel chain transmission device, such as Figure 5-6 As shown, including the aforementioned guide wheel chain, the hollow sleeve 200 is connected to a tooling fixture 500 outside the chain link unit 100.
[0031] like Figure 6 As shown, after the guide wheel chain is installed on the track bracket 400, two bearings 130 are symmetrically supported in the horizontal groove of the mounting groove 410, while the bottom 412 of the vertical groove can avoid the guide wheel frame 120. Continue as Figure 6 As shown, after the tooling fixture 500 is installed on the hollow sleeve 200, the hollow sleeve 200 may sink to some extent due to the force. The bottom 412 of the vertical groove can avoid the guide wheel frame 120, preventing the guide wheel frame 120 from touching the bottom and wearing out, which would damage the guide wheel chain transmission device.
[0032] like Figure 6 As shown, a limit nut is installed at the lower end of the hollow sleeve 200 to prevent it from detaching upward from the chain link unit 100, while the upper end of the hollow sleeve 200 is connected to the tooling fixture 500, so the tooling fixture 500 can prevent the hollow sleeve 200 from detaching downward from the chain link unit 100.
[0033] Here, the specific structure of the tooling fixture 500 is not limited.
[0034] In use, it is preferable to install a tooling fixture 500 every 1-5 chain link units 100, and the chain link unit 100 on which the tooling fixture 500 is installed has a bearing 130 installed. The weight of the tooling fixture 500 is transferred to the bearing 130, which plays a good role in bearing the load. Compared with the tooling fixture 500 being installed on the chain link unit 100 without the bearing 130, it can better prevent the guide wheel chain from being stretched or broken.
[0035] like Figure 2 Yes, a set of bearings 130 can be installed on the guide wheel chain at every other link unit 100. Optionally, the density of the bearings 130 can be selected according to actual needs, such as installing a set of bearings 130 at every three link units 100.
[0036] When the guide wheel chain of this utility model is in operation, it will not swing when it operates at low speed and bears a large tension. It significantly reduces the friction and loss of materials at the corners, and reduces the maintenance cost in daily use. The track brackets used for the guide wheel chain can be easily disassembled and repaired to avoid damage to the guide wheel chain.
[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
