Description

Technical Field

[0001] This utility model relates to the field of track guide wheel technology, specifically a guide wheel for transmission tracks. Background Technology

[0002] Track idlers are key components in tracked machinery and are widely used in equipment such as excavators, bulldozers, and tanks. They are usually located at both ends of the track and their main function is to guide the correct rotation of the track, prevent the track from deviating or going off track. At the same time, the tensioning device can be used to move the idlers back and forth to adjust the track tension and ensure the normal operation of the tracked equipment.

[0003] For the guide wheel, it is installed with a detachable bracket. The bracket and the wheel body are connected by a connecting shaft. In order to facilitate disassembly, a U-shaped mounting hole is often designed on the side of the bracket so that the connecting shaft can be inserted into the mounting hole laterally. When the connecting shaft needs to be installed or removed from the mounting hole, it is necessary to use external force to knock it out of the mounting hole. This process can easily damage the connection between the connecting shaft and the mounting hole.

[0004] Therefore, we propose a guide wheel for transmission tracks to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

However, when the connecting shaft needs to be installed or removed from the mounting hole, external force is required to forcefully push the connecting shaft out of the mounting hole, which can easily damage the connection between the connecting shaft and the mounting hole.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A guide wheel for a transmission track includes a main support and a guide wheel body mounted on one side of the main support.

[0010] Also includes:

[0011] The limiting plate is connected to the front end of the main bracket. A limiting plate groove is opened at the open end of the limiting plate. A limiting pressure block is rotatably connected in the groove of the limiting plate through a rotating shaft. The top of the limiting pressure block is flush with the top of the limiting plate.

[0012] Furthermore, a mounting plate is fixedly installed at the rear end of the main bracket, and positioning holes are provided on the surface of the mounting plate.

[0013] Furthermore, the front end of the main support is fixedly provided with two sets of connecting side plates that are fixedly connected to the limiting plate.

[0014] Furthermore, a wheel connecting shaft is inserted through the guide wheel body, and the end of the wheel connecting shaft is provided with an external thread.

[0015] Furthermore, a positioning hole is provided on the surface of the rotating shaft, and a washer plate is provided on the external thread of the shaft body.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a guide wheel for transmission tracks, which has the following advantages:

[0019] This invention features a limiting plate groove at the opening of the limiting plate, and the limiting pressure block can rotate under the connection of the rotating shaft. After the external thread of the shaft is inserted into the groove of the limiting plate, the two sets of limiting pressure blocks are rotated and pressed against the surface of the external thread of the shaft. The groove inner wall of the washer rod further presses the external thread of the shaft, giving it high stability. During subsequent disassembly and assembly, rotating the limiting pressure block outwards allows the external thread of the shaft to be easily pushed out of the groove of the limiting plate, greatly avoiding the possibility of damage caused by hitting or vibrating with tools.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1-3 As shown, an embodiment of the present invention provides a guide wheel for a transmission track, including a main support 1 and a guide wheel body 5 mounted on one side of the main support 1. Two sets of mounting plates 2 with a spacing are fixed on the back of the main support 1, and positioning holes are provided on the surface of the mounting plates 2. The entire guide wheel is installed through the mounting plates 2 and the positioning holes.

[0027] Two sets of connecting side plates 3 located on both sides of the main bracket 1 are fixed at the end of the main bracket 1 away from the mounting plate 2, and a limiting plate part 4 is fixed at the front end of the connecting side plate 3. The limiting plate part 4 adopts a side U-shaped structure, and its opening faces the side away from the main bracket 1. The opening is used to connect with the external thread 9 of the shaft that is inserted into the guide wheel body 5.

[0028] During assembly, the guide wheel body 5 is placed between the two sets of connecting side plates 3, and the external thread 9 of the shaft protruding from the center of the guide wheel body 5 to both sides is inserted into the groove of the external thread 9 of the shaft to complete the initial connection between the limiting plate part 4 and the external thread 9 of the shaft.

[0029] Subsequently, in order to enhance the stability of the external thread 9 of the shaft body in the groove of the limiting plate 4, a washer plate 6 is fitted over the external thread 9 of the shaft body, and at the same time, the threaded sleeve 7 is attached to the outside of the washer plate 6 so that the internal thread of the threaded sleeve 7 is threadedly matched with the external thread 9 of the shaft body at the end of the wheel body connecting shaft 8. The threaded sleeve 7 is driven by a tool and combined with the washer plate 6 to press the limiting plate 4 and the external thread 9 of the shaft body together.

[0030] Since the opening of the limiting plate part 4 is relatively large, a limiting plate groove 10 is opened on the surface of the opening end of the limiting plate part 4. At the same time, the rotating shaft part 11 is rotatably connected in the limiting plate groove 10, and a limiting pressure block 12 is fixed on the side of the rotating shaft part 11. The top of the limiting pressure block 12 is flush with the top of the limiting plate part 4, so that the washer plate 6 can press on the surface of the limiting plate part 4 and the limiting pressure block 12 at the same time. After the external thread 9 of the shaft is inserted into the groove of the limiting plate part 4, the limiting pressure block 12 is rotated to the position where the front end abuts against the surface of the external thread 9 of the shaft. At this time, by pressing the bottom surface of the limiting plate part 4 and the limiting pressure block 12 with the washer plate 6, the positioning effect of the external thread 9 of the shaft can be improved.

[0031] To further improve the limiting effect of the limiting pressure block 12 on the external thread 9 of the shaft and improve the assembly stability of the entire guide wheel, a positioning insertion hole 13 is opened on the surface of the limiting pressure block 12, and two sets of washer rods 14 that are inserted and connected to the positioning insertion hole 13 are fixed on the surface of the washer plate 6. It is worth noting that when the two sets of limiting pressure blocks 12 are pressed on the surface of the external thread 9 of the shaft, the two sets of washer rods 14 can correspond to the position of the positioning insertion hole 13.

[0032] The existing guide wheel structure is used for the bearing and sealing design of the guide wheel body 5, and will not be described in detail here.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
