Description
Technical field
The utility model relates to machine tool assembly field, refers to a kind of power transmission shaft opening up cutter lathe especially.
Background technology
The existing power transmission shaft for opening up cutter lathe is all solid shafting, and also have two countershafts to be arranged on the outside of main shaft, main shaft connecting machine tool power source, countershaft controls the transmission of other gears, but the defect of design is like this too space waste, and main shaft does not reach good effect with coordinating of countershaft, affect transmission and the working (machining) efficiency of lathe.
Utility model content
The utility model proposes a kind of power transmission shaft opening up cutter lathe, solve the above-mentioned problems in the prior art.
The technical solution of the utility model is achieved in that
A kind of power transmission shaft opening up cutter lathe, comprise main shaft and countershaft, described main shaft is the hollow shaft that inside is provided with cavity, described countershaft is arranged in the cavity of main shaft, be formed with gap between described main shaft inwall and countershaft outer wall, described main shaft one end is provided with its cavity inside of multiple connection and outside lubricant passage way.
As further improvement of the utility model, the bilateral symmetry that described main shaft one end is positioned at its central axis is provided with lubricant passage way.
As further improvement of the utility model, described lubricant passage way comprises horizontally disposed first oil circuit and the 3rd oil circuit, vertically disposed second oil circuit and the 4th oil circuit, described first oil circuit, the second oil circuit, the 3rd oil circuit, the 4th oil circuit connect successively and are communicated with the inside of spindle cavity and outside.
As further improvement of the utility model, described first oil circuit and the second oil circuit vertical connection, described second oil circuit and the 3rd oil circuit vertical connection, described 3rd oil circuit and the 4th oil circuit vertical connection, described first oil circuit, the second oil circuit, the 3rd oil circuit and the 4th oil circuit all with main shaft ft connection, described 4th oil circuit is also communicated with main shaft internal cavities.
The beneficial effects of the utility model are:
Countershaft is arranged in the cavity in main shaft by the power transmission shaft of this exhibition cutter lathe, save space, and lubricated by lubricant passage way between main shaft and the countershaft of its inside, can sufficient lubrication be obtained while main shaft and countershaft High Rotation Speed, improve operating efficiency and the machining accuracy of lathe.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the generalized section of the utility model main shaft along A-A direction;
Fig. 3 is the generalized section that the utility model main shaft coordinates with countershaft.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.
As shown in Figure 1 to Figure 3, a kind of power transmission shaft opening up cutter lathe, comprise main shaft 1 and countershaft 2, main shaft 1 is the inner hollow shaft being provided with cavity 11, countershaft 2 is arranged in the cavity 11 of main shaft 1, be formed with gap between main shaft 1 inwall and countershaft 2 outer wall, main shaft 1 one end is provided with the inner and outside lubricant passage way 3 of its cavity 11 of multiple connection, and lubricant passage way 3 is symmetrical set along the both sides of center transmission shaft axis.Lubricant passage way 3 comprises horizontally disposed first oil circuit 31 and the 3rd oil circuit 33, vertically disposed second oil circuit 32 and the 4th oil circuit 34, first oil circuit 31, second oil circuit 32, the 3rd oil circuit 33, the 4th oil circuit 34 connect successively and are communicated with the inside of main shaft 1 cavity 11 and outside.Wherein, first oil circuit 31 and the second oil circuit 32 vertical connection, second oil circuit 32 and the 3rd oil circuit 33 vertical connection, 3rd oil circuit 33 and the 4th oil circuit 34 vertical connection, first oil circuit 31, second oil circuit 32, the 3rd oil circuit 33 and the 4th oil circuit 34 all with main shaft 1 ft connection, the 4th oil circuit 34 is also communicated with main shaft 1 internal cavities 11.The cavity 11 of main shaft 1 inside is equivalent to a container, is used for storing lubricating oil, and lubricating oil is transported in the gap between main shaft 1 and countershaft 2 by the lubricant passage way 3 on main shaft 1 sidewall, to reach lubrication object.
Countershaft is arranged in the cavity in main shaft by the power transmission shaft of this exhibition cutter lathe, save space, and lubricated by lubricant passage way between main shaft and the countershaft of its inside, can sufficient lubrication be obtained while main shaft and countershaft High Rotation Speed, improve operating efficiency and the machining accuracy of lathe.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
