The model utility content
Technical problem to be solved in the utility model is to provide a kind of Armoured Vehicle, Heavy shaft coupling that can effectively reduce operating temperature.
The technical solution adopted in the utility model is: a kind of Armoured Vehicle, Heavy shaft coupling, comprise flange, intermediate mass, hexagon head bolt, splined shaft, fastening ring and side plate, wherein intermediate mass is between side plate and flange, the three links together by hexagon head bolt, periphery at intermediate mass is provided with fastening ring, splined shaft is installed in the inside of intermediate mass, its key is: be provided with spline fuel feeding axle in the outside of described splined shaft, this spline fuel feeding axle is grouped into by axis body part and disk body section, and the disk body of spline fuel feeding axle partly is positioned at the end of axis body part, and fixes with splined shaft; Axis body part at described spline fuel feeding axle offers first in-line and first oil circuit vertically, second in-line that first in-line is offered on circumferentially by disk body part is communicated with the 3rd in-line on the splined shaft, and the outlet of the 3rd in-line is on the circumferential surface of splined shaft; Second oil circuit that described first oil circuit is offered on circumferentially by disk body part is communicated with the 3rd oil circuit on the splined shaft, and the import of the 3rd oil circuit is on the circumferential surface of splined shaft.
Adopt above technological scheme, spline fuel feeding axle passes from the internal tooth casing of transmission case, and can be by the internal tooth casing driven rotary, the outer end of spline fuel feeding axle is stretched in the oil groove of transmission case bearing cap, the lubricant oil that enters by the bearing cap oil inlet hole is pressed into first in-line of spline fuel feeding axle from oil groove, enter the 3rd in-line on the splined shaft by second in-line again, enter shaft coupling inside from the outlet of the 3rd in-line at last and be lubricated.Lubricant oil enters the 3rd oil circuit on the splined shaft from the import of the 3rd oil circuit after the shaft coupling inner loop, flow to first oil circuit by second oil circuit on the spline fuel feeding axle again, and the spill port from the bearing cap flows back to transmission case at last.The utility model is by structural change, traditional pre-fuel feeding is become unconventional external pressure circulation fuel feeding, given full play to the ride quality of shaft coupling by the damping of stablizing oil pressure formation, what is more important: the heat that recycle oil is taken away has solved problems such as the shaft coupling operating temperature is too high, lack of lubrication, sealing rubber ring accelerated ageing effectively.
For simplified structure, to guarantee that lubrication oil circulation flows unimpeded, the import of above-mentioned first in-line is in the end of spline fuel feeding axle outer end. offer aperture at spline fuel feeding axle near the position of outer end, described first oil circuit communicates with the external world by aperture.
For the ease of sealing and help the stability of transmission of power, the axis body of above-mentioned spline fuel feeding axle partly is a terraced structure, and the excircle of axis body part enlarged diameter section is provided with external splines.
Beneficial effect: the utility model by suitable advance, the design and the reasonably sealing of oil circuit, can provide enough oil pressure for shaft coupling, given shaft coupling lubricated fully and best dimensionless damping constant; Taken away most heat simultaneously.The over-all properties of shaft coupling has been given full play in above-mentioned improvement, under the prerequisite that does not influence diesel powered system torsional vibration characteristic and technical order, has improved usability and life-span, has strengthened the reliability and the Security of power system.
