Abstract
The utility model relates to an axial plunger pump with a circulating oil passage. The axial plunger pump comprises a first cavity (3), a second cavity (4) and an oil passage (5); the first cavity (3) is formed between a rear cover of a pump body (1) and a cylinder body (2); the second cavity (4) is formed between the side wall of the pump body (1) and the side wall of the cylinder body (2); and the first cavity (3) is communicated with the second cavity (4) through the oil passage (5). Through the axial plunger pump, the lubricating property of a bearing on the pump cover can be improved, and the service life of the bearing can be prolonged.
Description
Technical field
The utility model belongs to the hydraulics field, particularly relates to a kind of axial piston pump with circulating oil path.
Background technique
In the A10VSO series axial piston pump that uses in the market, the oil circuit design on every side of the bearing on its pump cover is undesirable, oil circuit takes place easily stop up, so cause bearing under unlubricated situation, to turn round, has influenced the working life of bearing greatly.
The model utility content
The utility model technical problem to be solved provides a kind of axial piston pump with circulating oil path, can improve the working life of bearing.
The utility model solves the technological scheme that its technical problem adopted: a kind of axial piston pump with circulating oil path is provided, comprises the pump housing, cylinder body; First cavity; Second cavity, oil circuit is characterized in that: described pump housing bonnet and cylinder body form first cavity; Pump housing sidewall and cylinder side wall form second cavity, are communicated with through oil circuit between first cavity and second cavity.
Described oil circuit is dug on pump housing bonnet, and oil circuit has 3.
Described oil circuit is arc transition in the corner.
Beneficial effect
The utility model is designing the runner hole, on cylinder body, is boring 3 holes that become 120 degree angles for addressing this problem on the pump cover.Form a circulating oil path.Improve the lubricity of pump cover upper bearing (metal).
