Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and particularly relates to a shift fork connecting block. Background Art

[0002] Mill gearboxes used in steel mills are often high-speed and heavy-loaded. These gearboxes place high demands on the clutch's precision. Even the slightest wear can generate axial forces between the clutch's internal and external splines, causing the inner ring gear to overcome the pressure of the ball-bearing bolt's positioning spring, resulting in axial displacement and sliding friction with the clutch fork link. This can quickly wear through the fork's fixed stop, causing the clutch to shift out of its operating position and lose torque transmission. This necessitates opening the gearbox and replacing the worn parts, a time-consuming, labor-intensive, and costly process. Utility Model Content

[0003] Technical problems solved: In response to the above technical problems, the utility model provides a fork connecting block, which has the characteristics of simple structure, easy manufacturing, use and maintenance, and cost saving, and can meet the use requirements of steel rolling sites.

[0004] Technical solution: A shift fork connecting block for a clutch; comprising a shift fork body, a shift fork leg and a limit roller; the shift fork leg is U-shaped and is provided at the end of the shift fork body; the limit roller is detachably connected to the shift fork leg through a fixed block, and each shift fork leg is provided with two limit rollers, and the two limit rollers on the same shift fork leg are respectively located on both sides of the inner gear ring of the clutch.

[0005] Preferably, the fork body and the fork leg are integrally formed.

[0006] Preferably, the roller surface of the limiting roller is parallel to the end surface of the clutch inner gear ring.

[0007] Preferably, the roller surface of the limiting roller is 1 mm away from the end surface of the clutch inner gear ring.

[0008] Preferably, the limiting roller is a roller.

[0009] Preferably, the fixing block is connected to the fork leg via bolts.

[0010] Preferably, the limiting roller is connected to the fixing block via a bearing.

[0011] Beneficial Effects: The shift fork connecting block of this utility model replaces end-face contact with the inner ring gear with rolling friction, significantly extending its service life and reducing maintenance time, labor, and spare parts costs associated with wear. Since using this shift fork connecting block, the rolling mill has experienced no wear-related malfunctions, making maintenance easier and preventing damage to the gearbox's speed change clutch. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the utility model;

[0013] The numbers in the figure indicate the following meanings: 1. fork body, 2. fork foot, 3. limit roller, 4. fixing block, 5. inner gear ring. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0015] like Figure 1 As shown, a shift fork connecting block is used for a clutch, and in this embodiment, it is specifically used for the clutch of a rolling mill gearbox used in a steel rolling workshop. The shift fork connecting block includes a shift fork body 1, a shift fork foot 2 and a limit roller 3. The shift fork foot 2 is a U-shaped fork, which is arranged at the end of the shift fork body 1, and the shift fork body 1 and the shift fork foot 2 are formed in one piece. The limit roller 3 is detachably connected to the shift fork foot 2 through a fixing block 4, and each shift fork foot 2 is provided with two limit rollers 3. The two limit rollers 3 on the same shift fork foot 2 are respectively located on both sides of the clutch inner gear ring 5, and the roller surface of the limit roller 3 is parallel to the end face of the clutch inner gear ring 5, and is 1 mm apart, which can avoid the ball-shaped bolt on the inner gear ring 5 from being subjected to stress alone as much as possible.

[0016] Specifically, in this embodiment, the limiting roller 3 is a roller, the fixing block 4 is connected to the shift fork leg 2 via bolts, and the limiting roller 3 is connected to the fixing block 4 via a bearing.

[0017] The shift fork connecting block replaces end-face contact with the inner gear ring 5 with rolling friction, significantly extending its service life and reducing maintenance time, labor, and spare parts costs associated with wear. Since using this new shift fork connecting block, the rolling mill has experienced no wear-related malfunctions, making repairs easier and preventing damage to the gearbox's speed change clutch.
