Abstract
The utility model discloses a ceramimetallurgical sleeve gear for an automotive transmission. The ceramimetallurgical sleeve gear is characterized by consisting of a ceramimetallurgical gear ring and 39 ceramimetallurgical internal teeth, wherein the ceramimetallurgical internal teeth are fixed on the inner wall of the ceramimetallurgical gear ring; an annular stirring fork clamping groove is formed on the middle part of the outer wall of the ceramimetallurgical gear ring; standard involute spline grooves are formed between adjacent ceramimetallurgical internal teeth; the ceramimetallurgical gear ring and the ceramimetallurgical internal teeth are integrated; the ceramimetallurgical internal teeth are axially arranged at an equal interval; the lengths of the ceramimetallurgical interval teeth are consistent with the thickness of the ceramimetallurgical gear ring; and a middle tooth space stretching over two ceramimetallurgical internal teeth is formed every 11 ceramimetallurgical internal teeth. The ceramimetallurgical sleeve gear for the automotive transmission is simple in structure; and moreover, the ceramimetallurgical sleeve gear is pressed and sintered into a whole by using a ceramimetallurgical mixture, so that the ceramimetallurgical sleeve gear is easy to manufacture, low in manufacture cost and high in quality, and can be manufactured by a few machining procedures.
Description
Technical field
The utility model relates to the improvement that a kind of automotive transmission overlaps with tooth, specifically a kind of automotive transmission powder metallurgy toothed sleeve.
Background technique
Automotive transmission is by the tooth cover of shift fork sliding set on the tooth hub, the tooth hub again with output shaft on gear engagement, thereby realize gearshift.Present employed automotive transmission tooth cover is the turning of 20CrMnTi alloyed steel and is processed into, the tooth cover that this 20CrMnTi alloyed steel is made, and its deficiency is: complex manufacturing technology, cost of production are high, wear-resisting property is poor.
Summary of the invention
The purpose of this utility model is to provide a kind of easy processing, cost of production is low, wear-resisting property is high automotive transmission powder metallurgy toothed sleeve.
In order to reach above purpose, the embodiment that the utility model adopts is: this automotive transmission powder metallurgy toothed sleeve, it is characterized in that: it is made of powder metallurgy gear ring and powder metallurgy internal tooth, the powder metallurgy internal tooth is fixed on the inwall of powder metallurgy gear ring, outer wall middle part at powder metallurgy gear ring is provided with the shift fork annular slot, is standard involute splines groove between the adjacent powder metallurgy internal tooth; Described powder metallurgy gear ring and powder metallurgy internal tooth are an integral body; The powder metallurgy internal tooth is established 39 altogether, vertically equidistant arrangement, and the length of powder metallurgy internal tooth and the consistency of thickness of powder metallurgy gear ring, 11 the powder metallurgy internal tooths in every interval are established a middle teeth groove of striding two powder metallurgy internal tooths.
The utility model is also implemented by following measure: the outer diameter of described powder metallurgy gear ring is 95mm, and thickness is 21.8 mm; The width of shift fork annular slot is consistent with the wall thickness of shift fork, is 6 mm.
The raw material of described powder metallurgy gear ring and powder metallurgy internal tooth is: by weight percentage, copper powder 2-3%, nickel powder 3-4%, molybdenum powder 0.3-0.6%, graphite 0.6-0.8%, plasticizing agent 0.5-1%, surplus is the mixed powder of iron powder.
The beneficial effects of the utility model are: compare with the tooth cover with the automotive transmission that the turning of present 20CrMnTi alloyed steel processes, not only simple in structure, and owing to be by adopting copper powder, nickel powder, molybdenum powder, graphite, plasticizing agent, surplus is that the mixed powder compacting sintering of iron powder is an integral body, so make easily, machining processes is few, and fabricating cost is taken low, and quality is high.
