Description

Technical Field

[0001] This utility model relates to the field of walking mechanism technology, and in particular to anti-slip and wear-resistant steel track teeth. Background Technology

[0002] Anti-slip and wear-resistant steel track teeth are track support and transmission components used in engineering machinery (such as excavators, tanks, etc.). They are deeply embedded inside the rubber track, acting as a support frame, directly meshing with the machine's drive wheels, transmitting power and supporting the machine's weight, enabling the movement of devices and equipment when the transmission teeth and track teeth are engaged.

[0003] A search revealed Chinese patent publication number CN205574087U, which discloses a track tooth, including a bridge with left and right wings on both sides. The bridge is integrally formed with the left and right wings. Both the left and right wings have reinforcing ribs, and corresponding support bosses and engaging bosses are provided on the reinforcing ribs. The cross-sections of the support bosses and engaging bosses are rhomboid. The key feature is that ribs are provided below the support bosses and engaging bosses to support their ends, and the ribs coincide with the longer diagonal of the support boss or engaging boss. This track tooth provides good support for the ends of the support bosses and engaging bosses.

[0004] Although the aforementioned patents have been approved and can provide good support for the ends of the supporting boss and the snap-fit ​​boss, the bonding between the rubber material and the iron teeth is often not tight enough during the rubber injection molding process, resulting in insufficient connection strength. This weak connection is prone to slippage during equipment operation, especially under high load or complex terrain conditions, which seriously affects the normal operation and work efficiency of the equipment. Therefore, anti-slip and wear-resistant steel track iron teeth are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides anti-slip and wear-resistant steel track teeth, aiming to improve the problem of slippage caused by the inability of some devices to make good connection with the iron teeth during rubber injection molding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Anti-slip and wear-resistant steel track teeth include a base, a rubber sleeve is fixedly connected to the top of the base, a support mechanism is provided on the top of the base, and wear-resistant components are provided on the outside of the rubber sleeve.

[0008] The support mechanism includes two toothed blocks, which are externally fixedly connected to the top of the base. Multiple bent tubes are externally fixedly connected to the two toothed blocks. Injection holes are opened on the outside of the multiple bent tubes. Connecting rods are fixedly connected to the bottom of the multiple bent tubes. Reverse buckle components are fixedly connected to the bottom of the multiple connecting rods.

[0009] The above technical solution involves the rubber sleeve meshing with the transmission gear to drive the track rotation. The toothed blocks mesh with the transmission gear to ensure stable power transmission. During the rubber sleeve injection molding process, the bent tube and injection hole are filled with rubber material, forming a strong mechanical connection and enhancing the bonding strength between the rubber sleeve and the toothed blocks. The connecting rod and buckle assembly provide additional support and fixation, preventing the toothed blocks from bending or loosening during use, ensuring the structural stability of the entire device. This design not only improves the track's anti-slip and wear-resistant performance but also extends its service life and reduces maintenance costs.

[0010] As a further description of the above technical solution:

[0011] The reverse buckle assembly includes connecting plates, multiple connecting plates are externally fixedly connected to the bottom of multiple connecting rods, multiple connecting plates are externally fixedly connected to positioning posts, one side of the multiple positioning posts is fixedly connected to the outside of the toothed block, and multiple positioning posts are externally fixedly connected to locking rods.

[0012] The above technical solution achieves the following: the connecting plate and connecting rod of the reverse-locking assembly are fixedly connected, providing stable bottom support. The positioning post connects the connecting plate and the toothed block, enhancing the structural stability of the toothed block and preventing bending. The locking rod and rubber sleeve are tightly combined, enhancing connection strength and anti-slip performance, ensuring stable track operation, and improving reliability and service life.

[0013] As a further description of the above technical solution:

[0014] The wear-resistant component includes multiple right-angled blocks, which are externally fixed to both sides of the rubber sleeve, and rectangular grooves are formed inside the multiple right-angled blocks.

[0015] The above technical solution utilizes right-angled blocks fixed to both sides of the rubber sleeve to provide support and friction, preventing track slippage. Rectangular grooves reduce weight and prevent water accumulation, lowering component weight and preventing corrosion. This design allows for more flexible track movement.

[0016] As a further description of the above technical solution:

[0017] The interior of each of the right-angled blocks has through holes, and the exterior front of each of the right-angled blocks is fixedly connected to a top post.

[0018] The above technical solutions achieve the following: the interlocking holes reduce the weight of the right-angle blocks and increase friction, preventing track slippage. The top column provides additional friction and a limiting function, ensuring stable transmission and preventing track deviation. These designs improve track operating efficiency and safety, ensuring stable operation.

[0019] As a further description of the above technical solution:

[0020] The exterior of the plurality of interlocking holes extends through the interior of the right-angle block, and the exterior of the plurality of top posts is fixedly connected to the exterior of the right-angle block, i.e., to the exterior side near the rectangular groove.

[0021] The above technical solution involves: an insertion hole penetrating the interior of the right-angle block, reducing weight and increasing grip to prevent track slippage. A top post is fixed to the outside of the right-angle block near the rectangular groove, providing additional friction to ensure stable transmission.

[0022] As a further description of the above technical solution:

[0023] The exterior of the plurality of right-angled blocks forms a right-angled triangle, and the exterior of the plurality of top pillars is fixedly connected to one side of the exterior inclined surface of the right-angled blocks.

[0024] The above technical solution utilizes the right-angled triangular structure of the right-angled block to provide stable support and good friction, preventing track slippage. The top column provides additional friction when in contact with the drive gear.

[0025] As a further description of the above technical solution:

[0026] The interior of the bent tube is hollow, and the interiors of the multiple bent tubes are interconnected with the interiors of the multiple injection holes.

[0027] The above technical solution involves a hollow interior that penetrates the injection hole, where rubber material is filled during injection molding to form a strong connection.

[0028] As a further description of the above technical solution:

[0029] The two toothed blocks are triangular in shape on the outside, and the rubber sleeve is fitted inside the toothed blocks.

[0030] Through the above technical solution, the triangular structure of the tooth block provides stable support and good transmission performance, ensuring reliable power transmission.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the rubber sleeve meshes with the transmission gear to drive the track to rotate. During the injection molding process, the rubber material fills the bent tube and the injection hole to form a firm connection. At the same time, the rubber sleeve is tightly fitted on the outside of the tooth block, further enhancing the connection stability and reducing the anti-slip ability between the rubber sleeve and the tooth block, thus improving its efficiency.

[0033] 2. In this invention, the right-angled block and the rubber sleeve work together, providing good friction through their right-angled triangular structure. The rectangular groove and the interlocking hole together achieve weight reduction and water prevention, improving the overall performance of the wear-resistant components. The top column plays a limiting role during operation, ensuring stable transmission, preventing track deviation, and improving operating efficiency and safety. Attached Figure Description

[0040] 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.

[0041] Reference Figure 2 and Figure 4An embodiment of this utility model is provided: anti-slip and wear-resistant steel track teeth, including a base 1, a rubber sleeve 2 fixedly connected to the top of the base 1, which is designed to provide good friction so that it can be transmitted with the transmission gear to drive the track to rotate, a support mechanism 4 is provided on the top of the base 1, and a wear-resistant component 3 is provided on the outside of the rubber sleeve 2.

[0042] The support mechanism 4 includes two toothed blocks 41, designed for gear meshing. The two toothed blocks 41 are externally fixed to the top of the base 1. Multiple bent tubes 42 are externally fixed to the two toothed blocks 41, providing good connection and increasing the connection with the rubber sleeve 2, preventing slippage. During injection molding, the rubber sleeve 2, when fixed to the bent tubes 42, seals the bent tubes 42, increasing its connection. The multiple bent tubes 42 have injection holes 43 on their exterior, providing good connection. When the rubber sleeve 2 connects to the toothed blocks 41, injection molding fills the inside of the injection holes 43, causing some of the rubber sleeve 2 to engage within the injection holes 43 due to their shape, further increasing its connection. Connecting rods 44 are fixedly connected to the bottom of the multiple bent tubes 42, providing good support. The part is fixedly connected with a reverse fastening assembly 5, which includes a connecting plate 502. The connecting rod 44 enables good connection with the connecting plate 502. Multiple connecting plates 502 are fixedly connected to the bottom of multiple connecting rods 44. Positioning posts 501 are fixedly connected to the outside of multiple connecting plates 502. The design provides good support and prevents the toothed block 41 from bending during use. The outside of multiple positioning posts 501 is fixedly connected to the outside of the toothed block 41. A locking rod 503 is fixedly connected to the outside of multiple positioning posts 501. The design provides good locking ability so that the rubber sleeve 2 will surround and seal the locking rod 503 during injection molding, increasing its anti-slip ability. The inside of the bent tube 42 is hollow. The inside of multiple bent tubes 42 is interconnected with the inside of multiple injection holes 43. The outside of the two toothed blocks 41 is triangular, and the inside of the rubber sleeve 2 is fitted inside the toothed block 41.

[0043] Specifically, during operation, the rubber sleeve 2 meshes with the transmission gear, driving the track to rotate. During the injection molding process of the rubber sleeve 2, rubber material fills the interior of the bent tube 42 and the injection hole 43. Some of the rubber material is locked within the injection hole 43 due to its shape, thus forming a firm connection with the bent tube 42. Simultaneously, the interior of the rubber sleeve 2 is fitted over the exterior of the toothed block 41, further enhancing the connection with the toothed block 41. Furthermore, during injection molding, the rubber sleeve 2 also surrounds and seals the locking rod 503, ensuring a tight fit and increasing anti-slip capability. Additionally, when the device is in use, the locking rod 503 and the connecting plate 502 increase the contact between the rubber sleeve 2 and the toothed block 41, further enhancing its anti-slip ability.

[0044] Reference Figure 1 and Figure 3 The wear-resistant component 3 includes multiple right-angled blocks 31, which are designed to provide good support and friction. The multiple right-angled blocks 31 are externally fixedly connected to the outer sides of the rubber sleeve 2. The multiple right-angled blocks 31 have rectangular grooves 32 inside, which are designed to reduce the weight of the rubber sleeve 2 and prevent the accumulation of rainwater. The multiple right-angled blocks 31 have through holes 33 inside, which are designed to provide good friction and weight reduction. The multiple right-angled blocks 31 have top posts 34 fixedly connected to the front of the outside, which are designed to provide good limiting ability and increase the friction of the transmission gear. The multiple through holes 33 penetrate the inside of the right-angled blocks 31. The multiple top posts 34 are externally fixedly connected to the outside of the right-angled blocks 31, that is, to the outside side near the rectangular grooves 32. The outside of the multiple right-angled blocks 31 is a right-angled triangle, and the multiple top posts 34 are externally fixedly connected to one side of the external inclined surface of the right-angled blocks 31.

[0045] Specifically, multiple right-angle blocks 31 work in conjunction with the rubber sleeve 2. When the track is running, the right-angle blocks 31, utilizing their right-angled triangular structure, provide excellent friction. Simultaneously, the surface of the right-angle blocks 31 contacts the ground, and thanks to their wear-resistant material and design, generates sufficient friction to prevent track slippage. The rectangular grooves 32 inside the right-angle blocks 31 serve a dual purpose of weight reduction and water prevention during operation. The design of the rectangular grooves 32 reduces the amount of material used in the right-angle blocks 31, thereby reducing the weight of the entire wear-resistant component 3, making the track more flexible during movement and reducing energy consumption. Furthermore, the rectangular grooves 32 effectively prevent rainwater from accumulating inside the right-angle blocks 31, avoiding corrosion and additional weight burden caused by water accumulation, and extending service life. The design of the interlocking holes 33 further enhances the function of the right-angle blocks 31. When the track is running, the interlocking holes 33 increase friction; at the same time, the presence of the interlocking holes 33 also reduces the weight of the right-angle blocks 31, working together with the rectangular grooves 32 to improve the overall performance of the wear-resistant component 3. The top post 34 plays a crucial limiting role during track operation. When the track engages with the drive gear, the top post 34 contacts the drive gear, providing additional friction to ensure the stability and reliability of the transmission. Simultaneously, the design of the top post 34 prevents track deviation during movement, ensuring linear track motion and improving track operating efficiency and safety.

[0046] Working Principle: During the operation of the track teeth, the rubber sleeve 2 meshes with the transmission gear to transmit power and drive the track to rotate. During the injection molding of the rubber sleeve 2, the rubber material not only fills the internal space of the bent tube 42 but also flows into the injection hole 43. Due to the hollow nature of the injection hole 43, some of the rubber material fits tightly into the hole according to its shape, thus forming a very stable connection structure with the bent tube 42. Simultaneously, the inner side of the rubber sleeve 2 is tightly fitted and sleeved onto the outer side of the tooth block 41, further strengthening the connection between the rubber sleeve 2 and the tooth block 41. Furthermore, during the injection molding of the rubber sleeve 2, the locking rod 503 is also surrounded and sealed by the rubber material, resulting in a tight bond between the locking rod 503 and the rubber sleeve 2, significantly improving the anti-slip performance of the entire device. In actual use, the locking rod 503 cooperates with the connecting plate 502 to enhance the contact stability of the connection between the rubber sleeve 2 and the tooth block 41, thereby further improving the anti-slip capability of the track teeth and ensuring stable operation of the track under various working conditions.

[0047] During operation, the right-angle block 31 and the rubber sleeve 2 work together. The right-angle block 31, with its right-angled triangular structure, contacts the ground during track movement, generating sufficient friction through its wear-resistant material and design. Its internal rectangular groove 32 reduces material usage during operation, thus lightening the overall weight of the wear-resistant component 3, making track movement more flexible and reducing energy consumption. Simultaneously, the rectangular groove 32 prevents rainwater accumulation, avoiding corrosion and additional weight caused by water accumulation, extending service life. The interlocking hole 33 further enhances the function of the right-angle block 31, increasing friction and reducing weight during track movement, improving the overall performance of the wear-resistant component 3. The top post 34 contacts the gear when the track meshes with the drive gear, providing additional friction to ensure stable and reliable transmission, while preventing track deviation, guaranteeing linear motion, and improving operating efficiency and safety.
