Description
Technical field
The present invention relates to pump technical field more particularly to a kind of centrifugal pumps.
Background technique
High gear box space is limited, and lubrication needs the more complicated circulatory system, is increased using gear-box outside mostly and is followed
Equipment, the increased costs such as ring pump are more.
Summary of the invention
The problem of the purpose of the present invention is to solve background techniques, and a kind of structure proposed is simple, utilizes
High gear serves as the Semi surrounding type centrifugal pump of pump leaf.
To achieve the above object, the technical scheme adopted by the invention is that:
Semi surrounding type centrifugal pump, including gear housing are provided with the pump case for being packed into gear, the pump in the gear housing
The lateral fuel feed hole at the tooth root position of the corresponding gear inside and outside connection pump case, the interior bottom of chamber of the pump case are provided on the side wall of shell
Portion is provided with out oil groove, and the upper surface of described pump case is provided with the oil outlet being connected to oil groove out, the oil outlet connection oil transportation dress
It sets.
A further improvement of the present invention is that: the bottom of the pump case is provided with the vertical oil inlet for being connected to lateral fuel feed hole
Hole is provided with the cavity of storage lubricating oil between the pump case outer wall and the inner wall of gear housing.
A further improvement of the present invention is that: the longitudinal cross-section of the transverse direction fuel feed hole is arc-shaped, the arc diameter
Greater than gear root diameter and be less than its reference diameter.
A further improvement of the present invention is that: it is described to go out to connect between oil groove and oil outlet by arc-shaped oil discharge passage
It is logical, it is described go out oil groove and transverse direction fuel feed hole is parallel is correspondingly arranged.
A further improvement of the present invention is that: input shaft is arranged in the center of the gear, and the input shaft passes through pump case
Side wall is erected on the side wall of gear housing by bearing.
By adopting the above-described technical solution, the technological progress achieved by the present invention is:
Semi surrounding type centrifugal pump serves as pump leaf using high-speed rotary gear, and pump case and gear combination are the pump housing, are reduced dynamic
Power input, structure is simple, saves space.
Detailed description of the invention
