Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0026] In describing the present invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner ", "outside" and other indicated orientations or positional relationships are based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific Orientation, construction and operation in a particular orientation, therefore should not be construed as limiting the invention. In addition, the term...

The invention relates to the technical field of engineering machinery and particularly relates to a self-lubricating structure of a pumping rocker bearing and a pump truck. The self-lubricating structure of the pumping rocker bearing comprises a rocker arm, an annular bush, a spacer bush, a spherical bearing and a driving piston rod. The annular bush can rotate circumferentially arbitrarily; lubricating grease in a front lubricating oil channel in a bearing pedestal successively enters a first oil tank and a second oil tank of the annular bush and then enters between the spherical bearing anda bulb of a piston rod of an oil cylinder through the chromeplated spacer bush, the rocker arm and an oil hole of the spherical bearing; driven by the oil cylinder, once the rocker arm swings, a synchronous lubricating pump injects the lubricating grease into the lubricating part between the spherical bearing and the bulb of the piston rod of the oil cylinder through the channel, so that smoothness between a fixed part and a movable part is achieved; the spherical bearing of the pumping rocker arm (the important mechanism) is automatically lubricated with a relatively low cost; the service life of the spherical bearing is prolonged and the gap adjusting period is prolonged; the lubricating grease is injected immediately, so that the swinging range of the rocker arm is guaranteed and the pumping efficiency is increased.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a pumping rocker arm bearing self-lubricating structure and a pump truck. Background technique [0002] At present, in the field of construction machinery, especially on pump trucks, the pumping distribution rocker mechanism includes rocker arms, tube shafts, piston rods and other components. Rotating in the seat, during the working process, the ball head of the cylinder piston will have a great impact on the spherical bearing. If the lubrication is poor, it will easily cause early wear of the spherical bearing, reduce the swing range of the rocker arm, and reduce the pumping efficiency. At present, the lubricating method of the rocker arm bearing is: install an oil cup above the rocker arm, the oil hole leads to the two spherical bearings, and manually add lubricating grease regularly. However, when the actual equipment is used, the lubricating grease is not filled...
