Description
Technical field
The invention belongs to technical field of engines, specifically, relate to a kind of reverse gear embedded engine countershaft combination.
Background technique
General reverse gear embedded engine countershaft combination is made of parts such as countershaft, first gear, second gear, three retaining gears, reverse gear, four retaining gears and axle sleeves.Wherein three retaining gears and four retaining gears are installed on the countershaft by the key and the keyway of Spielpassung respectively, first gear, second gear and reverse gear also are sleeved on the countershaft, reverse gear is between three retaining gears and four retaining gears, second gear is positioned at the outside of four retaining gears, and first gear is positioned at the outside of three retaining gears, is provided with axle sleeve between annular boss in the middle part of first gear and the countershaft.When motor hangs up when reversing gear, drive countershaft first gear (idle running) by the main shaft first gear, again by the countershaft first gear drive big end of joint shaft gear that reverses gear, the small end of joint shaft gear of reversing gear drives the driven gear that reverses gear, at last, drive the countershaft reverse gear, thereby realize reversing gear by the driven gear that reverses gear.
The countershaft in the existing reverse gear embedded engine countershaft combination and the structure of first gear do not have the reference of the two-wheel vehicle of reversing gear motor from tradition and come, on the wall of countershaft, offer the countershaft oilhole that radially connects to its center hole, have the axle sleeve oilhole on the wall of corresponding axle sleeve, lubricant oil enters in the center hole of countershaft like this, a part forms a small amount of oil film by the surface of contact that the countershaft oilhole enters axle sleeve and countershaft, and another part enters by the axle sleeve oilhole that the surface of contact of annular boss and axle sleeve forms a small amount of oil film in the middle part of the first gear again simultaneously.Because the countershaft first gear will bear certain load, and reverse gear embedded motorcycle uses when reversing gear more, lubricate good between inevitable requirement countershaft and the axle sleeve and between axle sleeve and the countershaft first gear, existing structure between countershaft and the axle sleeve and a small amount of oil film that forms between axle sleeve and the countershaft first gear be difficult to satisfy lubricating requirement, can produce friction on the surface that they are in contact with one another, and the friction-produced resistance, should consumption of power, make parts heating, wearing and tearing again, also can cause working surface generation ablation phenomenon.
Summary of the invention
Technical problem to be solved by this invention is to provide lubricated good reverse gear embedded engine countershaft combination between a kind of countershaft, axle sleeve and the countershaft first gear three.
Technological scheme of the present invention is as follows: a kind of reverse gear embedded engine countershaft combination, comprise countershaft, first gear and axle sleeve, wherein first gear is sleeved on the countershaft, axle sleeve is between the annular boss and countershaft of first gear central authorities, on the wall of countershaft, offer the countershaft oilhole that radially connects to its center hole, offer the axle sleeve oilhole on the wall of corresponding axle sleeve, its key is: the countershaft outer peripheral surface in described countershaft oilhole outlet port is provided with annular oil groove, the shaft axis of this annular oil groove overlaps with the shaft axis of countershaft, and annular oil groove communicates with countershaft oilhole and axle sleeve oilhole respectively; Also offer oil groove on the inwall of described first gear annular boss, two of this oil groove connects the both ends of the surface to annular boss respectively.
Adopt above technological scheme, because the countershaft outer peripheral surface in countershaft oilhole outlet port is provided with the annular oil groove that communicates with countershaft oilhole and axle sleeve oilhole respectively, make the lubricant oil that flows to the axle sleeve oilhole from the countershaft oilhole between the surface of contact of countershaft and axle sleeve, to form thicker oil film, satisfied the lubricating requirement of countershaft and shaft room; In addition, on the inwall of first gear annular boss, offer oil groove, make the lubricant oil that flows to first gear annular boss inwall from the axle sleeve oilhole between the surface of contact of axle sleeve and first gear, form generouser oil film, satisfied the lubricating requirement between axle sleeve and first gear.
The above-mentioned oil groove that is opened on the annular boss inwall is a spirality, and its pitch equates substantially with the thickness of annular boss.Make that like this oil film that forms between the surface of contact of axle sleeve and first gear is generouser, be more evenly distributed, can reach better lubrication effect as much as possible.
Beneficial effect: the present invention has characteristics such as novel, simple in structure, that enforcement is easy, it can guarantee between countershaft, axle sleeve and the countershaft first gear three lubricated good, effectively reduced the surface friction drag that produces on the surface that they are in contact with one another, prevented that parts from heating and wearing and tearing taking place, eliminated the generation of working surface ablation phenomenon, when ensureing the engine countershaft composite behaviour, prolonged the working life of associated components such as countershaft, axle sleeve and countershaft first gear greatly.
