Description

Lubricating structure of high-pressure oil pump Technical Field The utility model relates to the technical field of oil pump lubrication, in particular to a high-pressure oil pump lubrication structure. Background When the high-pressure oil pump is used for supplying oil, the plunger reciprocates in a linear motion, the plunger is required to be lubricated, and as one end of the head of the plunger is directly contacted with oil, the oil has certain lubricity, and therefore the one end of the head of the plunger is generally not required to be additionally lubricated by using lubricating oil. The tail end of the plunger is generally required to be additionally lubricated by using lubricating oil, at present, the lubricating oil is mainly sprayed on the surface of the tail end of the plunger, and although the lubricating effect can be achieved, the lubricating oil sprayed on the surface of the tail end of the plunger is easy to form oil drops, the loss is quicker, a larger amount of lubricating oil is required to be used for continuous oil spraying when the lubricating oil is required to be kept, the oil consumption is large, and the lubricating oil is difficult to ensure that the surface of the tail end of the plunger can be uniformly sprayed. Disclosure of utility model The utility model aims to provide a lubricating structure of a high-pressure oil pump, which aims to solve the problems in the background art. The high-pressure oil pump lubricating structure comprises a pump body, a driving shaft and a plunger which are arranged in the pump body, a connecting rod which is rotatably arranged on the eccentric position of the outer wall of the bottom of the driving shaft, a traction rod which is rotatably arranged on the connecting rod, a driving conical tooth ring which is arranged on the outer wall of the bottom of the driving shaft, a supporting plate which is arranged on the inner wall of the bottom of the inner cavity of the pump body, a lubricating assembly which is rotatably arranged on the outer wall of one side of the supporting plate, and a driven conical tooth ring which is arranged on the outer wall of the lubricating assembly. The driving conical toothed ring is meshed with the driven conical toothed ring. The lubricating assembly comprises an annular shell, a plurality of balls which are arranged on the inner wall of the annular shell in a rolling manner and distributed at equal intervals, and an oil injection pipe which is connected to the inner wall of one side of the annular shell.
