Abstract
The utility model discloses the lubricating systems that a kind of unmanned plane starts train unilateral bearing, including bent axle, bent axle, start gear gear, unilateral bearing and crankcase, lubricate the unilateral bearing started between train and bent axle by quoting the oil gas in crankcase.Oil gas inside crankcase enters axis hole bottom along hollow bent axle, and passes through axis hole bottom and connected through bent axle with the oil-gas hole of axle sleeve radial direction inside unilateral bearing, is finally returned on the top of unilateral bearing by the oil-gas hole on crankcase body inside crankcase.
Description
Technical field
The utility model discloses the lubricating systems that a kind of unmanned plane starts train unilateral bearing, can be used as more rotors
The equipment such as unmanned plane, propeller-parachuting, model plane engine starts the lubricating system of train unilateral bearing, belongs to field of power machinery.
Background technology
Medium and heavy rotor wing unmanned aerial vehicle (more than 100kg) is most at present uses internal combustion engine as power, and during internal combustion engine start
It needs to provide power with starter and starting train, since the starting train only works in engine start, in engine
The train stops operating after start completion, therefore, starts and is generally required between the output gear of train and bent axle by one-way shaft
Hold connection.
Between gear and rotation axis common unilateral bearing be the ball-type unilateral bearing with gasket, lubricating system one
As for grease lubrication, and the starting train of unmanned plane is since bulk limits, and unilateral bearing can only select more compact structure
Needle-type, this needle bearing do not applied to grease lubrication, it is necessary to design a kind of dedicated oil gas or oil mist system.
The content of the invention
A kind of unmanned plane in view of the deficiencies of the prior art, the present invention proposes uniqueness starts the lubrication of train unilateral bearing
Mode is quoted the oil gas in crankcase by the oil-gas hole circuit being distributed in bent axle/bent axle and crankcase, efficiently solved
Unmanned plane starts the lubrication problem of train unilateral bearing.
The technical proposal of the invention is realized in this way：The oil gas of machine oil is mixed in crankcase along the axis hole 2 on bent axle 1
Into axis hole bottom, the oil-gas hole 3 through bent axle radial direction is equipped in the bottom of axis hole 2, oil gas enters bent axle 1 by oil-gas hole 3
The annular groove 10 in outside；It is connected through a screw thread simultaneously in 1 outside of bent axle and bent axle 4 is installed, unilateral bearing 7 is mounted on bent axle 4
Outside, inside and outside oil-gas hole 6 is designed in bent axle with 10 sustained height of annular groove, and oil gas passes through the hole from annular groove 10
Into inside unilateral bearing, its internal structure is lubricated.Since the junction of 1 axle journal of bent axle and crankcase is provided with gasket
Ball bearing causes 7 top of unilateral bearing can not be directly with being connected inside crankcase, and the present invention is in unilateral bearing and crankshaft journal
Between the ball bearing at place be equipped with inside and outside horizontal oil-gas hole 8, oil gas by the oil-gas hole 8 from unilateral bearing top again
It is communicated with inside crankcase, forms complete oil-air lubrication circuit, ensure the effectively lubricating of unilateral bearing.
Description of the drawings
Fig. 1 is the structure diagram that a kind of unmanned plane starts train unilateral bearing lubricating system.1 bent axle, 2 axis holes, 3 in figure
Oil-gas hole, 4 bent axles, 5 start gear gear, 6 oil-gas holes, 7 unilateral bearings, 8 oil-gas holes, 9 crankcases.
Fig. 2 is the half-section diagram of bent axle 1, and 10 be annular groove on the outside of bent axle in figure.
Fig. 3 is the partial schematic diagram on unilateral bearing top.
Specific embodiment
The present invention will be described with reference to the accompanying drawings and examples.
The lubricating system of unilateral bearing of the present invention by quote the oil gas in crankcase lubricate start train and bent axle it
Between unilateral bearing, the oil gas circuit of the lubricating system is：--- axis hole 2 --- oil-gas hole 3 --- crankshaft collar inside crankcase
--- --- unilateral bearing 7 --- oil-gas hole 8 --- is inside crankcase for oil-gas hole 6 for slot 10.
