Description

Technical Field

[0001] This utility model relates to the field of automotive tensioner technology, specifically to a structurally stable automotive tensioner. Background Technology

[0002] Automotive tensioners are important components in the transmission system of automobile engines, mainly used to adjust the tension of belts to ensure the stable operation of the transmission system. Existing automotive tensioners typically consist of bearings, a pulley body, an outer ring, and a bracket, and these components are mostly integrally molded structures.

[0003] However, this design has the following drawbacks in practical use:

[0004] 1. High maintenance costs: Since the outer ring and the wheel body are molded as one piece, when the outer ring wears out due to long-term friction, the entire tensioner must be replaced, and the outer ring cannot be replaced separately, which leads to a significant increase in maintenance costs.

[0005] 2. Inconvenient disassembly: The one-piece design makes the replacement of the outer ring complicated, requiring the removal of the interference fit bearing, which increases the difficulty and time cost of maintenance.

[0006] Therefore, we propose a structurally stable automotive tensioner. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a structurally stable automotive tensioner that facilitates the individual replacement of easily worn outer rings, reduces subsequent maintenance costs, and offers other advantages such as structural stability, effectively solving the problems in the background technology.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a structurally stable automotive tensioner wheel, comprising a wheel body, a bearing installed inside the wheel body, an outer ring provided outside the wheel body, a mounting plate fixedly installed on the outer wall of the wheel body, a slot provided on one side of the outer surface of the mounting plate, the upper end of the slot extending through to the upper outer surface of the mounting plate, a limiting pin provided in the slot, the lower outer surface of the limiting pin being fixedly connected to the bottom of the slot, a threaded hole provided on the upper outer surface of the limiting pin, reinforcing ribs fixedly installed between the two outer surfaces of the mounting plate and the outer wall of the wheel body, an insert plate fixedly installed on the inner wall of the outer ring, a pin hole provided on the upper outer surface of the insert plate, the pin hole extending through to the lower outer surface of the insert plate, and a hidden hole provided above the pin hole.

[0011] Preferably, the outer wall of the insert plate is inserted into the slot, and the insert plate is sleeved on the outer wall of the limiting pin through a pin hole.

[0012] Preferably, the internal hexagon countersunk head bolt passes through the concealed hole and is threaded into the threaded hole.

[0013] Preferably, the outer ring and the insert plate are integrally molded structures, and the wheel body, mounting plate and reinforcing rib are integrally molded structures.

[0014] Preferably, the diameter of the pin hole matches the outer diameter of the limiting pin, and the diameter of the hidden hole is larger than the head diameter of the internal hexagon countersunk bolt.

[0015] Preferably, the reinforcing rib is a triangular prism structure.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a structurally stable automotive tensioner, which has the following advantages:

[0018] 1. This type of stable automotive tensioner features a detachable connection design. The outer ring is fixed to the wheel body using insert plates, limit pins, and bolts. When the outer ring wears out, it can be replaced simply by removing the internal hexagon countersunk bolts, eliminating the need to replace the entire tensioner and significantly reducing maintenance costs and material waste.

[0019] 2. This type of stable automotive tensioner wheel features reinforcing ribs that facilitate the reinforcement of the mounting plate, thereby improving structural stability and load-bearing capacity.

[0020] 3. This type of stable automotive tensioner wheel, with its insert plate and slot, combined with the fixing method of limit pins and bolts, makes the installation and disassembly of the outer ring simple and quick, reducing maintenance time and improving maintenance efficiency.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] This embodiment is a structurally stable automotive tensioner.

[0028] like Figure 1-4 As shown, the device includes a wheel body 1, a bearing 2 installed inside the wheel body 1, an outer ring 3 on the outside of the wheel body 1, and a mounting plate 4 fixedly installed on the outer wall of the wheel body 1. A slot 8 is opened on one side of the outer surface of the mounting plate 4, and the upper end of the slot 8 extends through to the upper outer surface of the mounting plate 4. A limit pin 9 is provided in the slot 8, and the lower outer surface of the limit pin 9 is fixedly connected to the bottom of the slot 8. A threaded hole 10 is opened on the upper outer surface of the limit pin 9. Reinforcing ribs 5 are fixedly installed between the two outer surfaces of the mounting plate 4 and the outer wall of the wheel body 1. An insert plate 6 is fixedly installed on the inner wall of the outer ring 3. A pin hole 11 is opened on the upper outer surface of the insert plate 6, and the pin hole 11 extends through to the lower outer surface of the insert plate 6. A hidden hole 12 is provided above the pin hole 11.

[0029] The outer wall of the insert plate 6 is inserted into the slot 8. The insert plate 6 is fitted onto the outer wall of the limit pin 9 through the pin hole 11. The internal hexagon countersunk bolt 7 passes through the hidden hole 12 and is threadedly connected to the threaded hole 10. The outer ring 3 and the insert plate 6 are integrally formed. The wheel body 1, the mounting plate 4 and the reinforcing rib 5 are integrally formed. The diameter of the pin hole 11 matches the outer diameter of the limit pin 9. The diameter of the hidden hole 12 is larger than the head diameter of the internal hexagon countersunk bolt 7. The reinforcing rib 5 is a triangular prism structure.

[0030] It should be noted that this utility model is a structurally stable automotive tensioner. The wheel body 1, bearing 2, and outer ring 3 are all existing technologies and can be readily understood by those skilled in the art, so they will not be described in detail here. When installing the outer ring 3, the insert plate 6 is placed on the outside of the wheel body 1, and the insert plate 6 on the inner wall of the outer ring 3 is inserted into the slot 8. The insert plate 6 is fitted onto the outer wall of the limiting pin 9 through the pin hole 11. Then, the internal hexagon countersunk bolt 7 is connected to the threaded hole 10 at the top of the limiting pin 9, and the top of the internal hexagon countersunk bolt 7 is limited in the hidden hole 12, thus realizing the assembly of the outer ring 3. It is easy to disassemble and replace the easily worn outer ring separately, reducing the later maintenance cost. The reinforcing rib 5 is provided to strengthen the mounting plate 4, improve the structural stability, and improve the load-bearing capacity.
