Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of tracked armored vehicle of the present utility model is cranked arm lubricating structure with inducer, the mechanism by
Crank arm 1, drag ring 2, round section joint ring 3, induction wheel support 4, bushing 5 forms.
Crank arm 1 with bushing 5 by gap coordinate fix, bushing 5 with induction wheel support 4 pass through be interference fitted fix, friction
Ring 2, which is assemblied in, is cranked arm between 1 and induction wheel support 4, and round section joint ring 3 is assemblied in the grooves on two sides of bushing 5.
Bushing 5 is interference fitted by smooth, cylindrical peripheral surface with induction wheel support 4 and fixed, and plays a part of static seal, common group
Into the flow channel of lubricating oil.
Bushing 5 has inside and outside double-deck oil storage slot structure, and oil storage tank is also the passage of lubricating oil.
Round section joint ring 3 is bushing both ends potted component.
Crank arm and 1 coordinated with bushing 5 by gap and fix, both sides round section joint ring 3 seals, and bushing 5 and induction wheel support 4 are logical
Interference fit is fixed, and forms static seal, collectively constitutes the flow channel of lubricating oil.When cranking arm 1 transmission circumferential with bushing 5,
Drag ring 2 be located at crank arm 1 section part, drag ring 2, which plays, prevents 1 section abrasive action of cranking arm.
Bushing 5 has inside and outside double-deck oil storage slot structure.Axially being uniformly distributed 9 in its inner cylinder face, (section radius are
1.5mm semicircle) straight-line groove, straight-line groove both ends are respectively equipped with annular groove, and width is respectively 3mm and 6mm.Annular is recessed
Groove both ends are respectively provided with the annular groove that a width is 4.2mm, and the annular groove is used to place round section joint ring 3.
It is 12mm to be axially arranged with width in the external cylindrical surface of bushing 5, and depth is 1.5mm wide groove (axial direction), and
Connected by a diameter of 6mm of right-hand member circular hole and inner cylinder face annular groove.Oil-out is diameter 3mm circular hole, is arranged on note
The relative position (position correspondence on axial direction, being all left end) of hydraulic fluid port, reaches farthest path.During oiling, for excluding in oil duct
Portion's gas, reduce fill cup hydraulic, when oil outlet flows out lubricating oil, that is, show that all oil ducts in the inside of bushing 5 have been filled with, now
Oiling can be stopped, and the sealing bolt of pouring orifice and oil-out is tightened.
Oiler 6 and the circumferencial direction of oil-out 7 are into 180 degree, oil-out 7 and the position correspondence on the axial direction of oiler 6, i.e., on
Lower correspondence.
