In order to reduce the rotational friction between the rotating shaft and the rocker arm, a bearing connection mode can be adopted, in the embodiment, the economical efficiency and the replaceability are more considered, and for this reason, the following measures are taken in the embodiment:
firstly, a fixed sleeve 4 is sleeved on a rotating shaft 3, the fixed sleeve 4 is divided into three parts, namely a middle part and two end parts at two ends, wherein the two end parts can penetrate through holes in the rocker arm, then, a connecting sleeve 5 is sleeved on the middle part of the fixed sleeve 4, and rotating sleeves, namely a first rotating sleeve 6 and a second rotating sleeve 7, are sleeved on the end parts of the fixed sleeve 4. The first rotating sleeve 6 is fixedly connected with the first rocker arm 1, and the second rotating sleeve 7 is fixedly connected with the second rocker arm 2. Thus, the shaft 3 comprises a fixed sleeve 4 which is sleeved outside the shaft 3 and rotates relative to the first rotating sleeve 6 and the second rotating sleeve 7, and the connecting sleeve 5 is used for preventing the two rocker arms from approaching to the middle. It will be appreciated that the inner and outer diameters of the first and second rotating sleeves 6, 7 and the connecting sleeve 5 should be similar without any problem of mutual nesting, and it will also be appreciated that the outer ends of the first and second rotating sleeves 6, 7 are adjacent to the end of the shaft 3 and are constrained by a nut or the like at the end of the shaft 3 having a larger outer diameter, for example the inner diameter of the first rotating sleeve 6 is smaller than the outer diameter of the nut, so that the movement of the two rockers in the axial direction of the shaft is constrained to only rotate relative to the shaft.
In this embodiment, the connecting sleeve 5 is in clearance fit with the fixing sleeve 4, so that the relative movement of the two rocker arms is prevented from being blocked due to the interference fit between the two rocker arms and the like.
In this embodiment, the first rotating sleeve 6 is riveted to the first rocker arm 1, and similarly, the second rotating sleeve 7 is riveted to the second rocker arm 2.
