Abstract
The invention discloses dule lead helical cooling water jacket that includes tube jacket body (1), dule lead helical groove is set on the wall or ektexine; at one end of thejacket body (1), two helical groove are separately form cooling liquid inlet and outlet, the inlet and outlet are connected with the cooling liquid circling system; at the other end of thejacket body (1), connecting slot is set between two helical groove. By said technique scheme, the dule lead helical cooling water jacket of the invention can realize the effective cooling of the element which is to be cooled, because the inlet and outlet are at one side, it is convenient to interface; adopting the dule lead helical groove, the cooling area is big, especially fit for the outer rotor moment motor, and it can be used as cooling component of stator.
Description
Technical field
The present invention relates to a kind of coolant jacket, in particular, relate to the set-up mode of cooling bath on the cooling body.
Background technology
The method of the cooling effectiveness of traditional raising recirculated water mainly is to strengthen the flow velocity of cooling water and increase effective contact area.When the flow velocity increasing, pressure is also along with increase; Pressure increase meeting is increased the seal request of system.And the water-tight equipment of high request is difficult to realize in some mechanical structure.
Summary of the invention
At the problems referred to above, the invention provides a kind of cooling element---dual-lead spiral cooling water cover, in the confined space, by two helical pitch spiral coolant jackets the heat that mechanical movement produces is taken away rapidly, to reach quick cooling purpose.
To achieve these goals, the present invention has designed a kind of dual-lead spiral cooling water cover, comprises the tubulose body, and the inwall of body or outer wall are offered two helical pitch helicla flutes.In an end of body, two helicla flutes form cooling liquid inlet and cooling liquid outlet respectively, and import and outlet are communicated with coolant circulation system.In the other end of body, offer connectivity slot between two helicla flutes.
By technique scheme, dual-lead spiral cooling water cover of the present invention needing can realize effective cooling of cooling element, because open in a side import/export, has interface characteristics easily; And adopting two helical pitch helicla flutes, film-cooled heat is big.Particularly be fit to external-rotor-type force moment motor, as the cooling device use of stator.

Fig. 2 is the outside drawing of a kind of embodiment of dual-lead spiral cooling water cover of the present invention;
Fig. 3 be dual-lead spiral cooling water cover of the present invention partly cut open structural representation;
Fig. 4 be relative Fig. 3 other direction partly cut open structural representation;
Fig. 5 lead spiral cooling water cover of the present invention is used for the user mode schematic diagram of single axle table.
Embodiment
The surface structure of a kind of embodiment of dual-lead spiral cooling water cover of the present invention as shown in Figure 2.At the body inwall dual-lead spiral cooling bath is set.Certainly, as required, cooling bath also can be opened in the body outer wall.
Two helical pitch spirals through being commonly used on the worm screw, are called two helical pitch helical worms.The principle of two helical pitch spirals as shown in Figure 1, two helicla flutes or screw thread are under deployed condition, lead angle θ is equal fully.
With reference to figure 3 and Fig. 4 dual-lead spiral cooling water cover of the present invention is described, at an end of body 1, two helicla flutes form cooling liquid inlet and cooling liquid outlet respectively, and import and outlet are communicated with coolant circulation system; In the other end of body 1, offer connectivity slot 2 between two helicla flutes.
During work, shown in arrow among the figure, cooling fluid enters a helicla flute from the import of body lower end, enters another helicla flute in the body upper end by connectivity slot 2 cooling fluids, be back to the outlet of body lower end, thereby realize refrigerating function down assisting of coolant circulation system.
Fig. 5 has shown a kind of occupation mode of coolant jacket of the present invention, and AC permanent-magnet synchronous external rotor torque motor drives single axle table among the figure, and the rotor 5 ' of motor directly links to each other with turntable table top 2 ', and table top 2 ' utilizes the end of bolt in rotor 5 ' usually.Simultaneously, the fixing housing 9 ' of the stator 6 ' that is positioned at rotor 5 ' inner ring and turntable is connected by bolt.Be placed with permanent magnet on the inwall of rotor 5 ', be provided with brake mechanism 4 ' in rotor exterior.Wherein cold cover 8 ' is positioned at stator 6 ' inside in the present invention.The axial/radial bearing 1 ', the bearing that have also shown the turntable special use among Fig. 5 are provided with encoder 7 ' and lip seal circle 3 '.
The above; only be the preferable embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
