Embodiment Construction

[0022] 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.

[0023] see figure 1 As shown, a gear pump includes a casing and a gear mechanism. The shell can be a hollow shell, and the gear mechanism is arranged inside the shell.

[0024] The casing includes an inner pump casing 41 and an outer pump casing 42 . The inner pump casing 41 can be a hollow cylindrical structure, and the central axis of the inner pump casing 41 is parallel to the axis of the gear mechanism. That is, the inner pump casing 41 is arranged outside the gear mechanism along the axial direction of the gear mechanism, so as to wrap the gear mechanism inside the inner pump casing 41 .

[0025] An outer pump casing 42 is sheathed on the outer side of the inner p...

Abstract

The invention provides a gear pump which comprises a gear mechanism and a casing for containing the gear mechanism, wherein the casing comprises an inner pump casing and an outer pump casing; the outer pump casing is arranged on the outer side of the inner pump casing in a sleeving manner; a central axis of the inner pump casing is parallel to an axis of the gear mechanism; a first opening and a second opening penetrating through the casing wall of the pump casing are formed in the outer pump casing; a channel is formed in an outer wall of the inner pump casing; one end of the channel is communicated with the first opening; the other end of the channel is communicated with the second opening; a cooling medium circulates in the channel. The gear pump disclosed by the invention is simple instructure, excellent in heat dissipation effect and convenient to maintain.

Description

technical field [0001] The present invention relates to a gear structure, and more particularly, to a gear pump. Background technique [0002] The gear pump is a rotary pump in which two meshing gears are closely fitted together and rotate in a housing to form a working volume change and movement to transport liquid or pressurize it. When the gear rotates, the volume of the space on the disengaged side of the gear changes from small to large, forming a vacuum to suck the liquid, and the volume of the space on the meshing side of the gear changes from large to small, and squeezes the liquid into the tube. [0003] During this operation, high temperature is easily generated inside the gear pump. Due to the structural characteristics of the gear pump itself, it is very difficult to dissipate the heat generated. When the gear is effectively dissipated, the fine structure of the gear will change when it is heated, resulting in no actual meshing of the gear or excessive friction ...
