The utility model discloses a kind of CVT automatic transmission V-type belt shaft fine forge piece, comprise input end, belt wheel and shank, described input end is arranged on the lower end of belt wheel, described input end is frustum cone structure, the angle with wheel face and horizontal plane formation of described belt wheel is 11 °, and the another side of the described peripheral belt wheel of input end is provided with the round bump with external tooth; The upper end of described belt wheel is the taper off cylindrical shank of trend of external diameter; Described fine forge piece is overall structure.This fine forge piece adopts the compound molding of warm cold closed-die forging technology; reduced the more problem of machine tooling flank of tooth equipment investment that adopts; with short production cycle; manufacturing efficiency is high, and constant product quality has been saved resource; protected environment; can meet required precision, reduce again manufacture cost, also meet the trend of world today's development of manufacturing simultaneously.
Description
Technical field
The utility model relates to driving belt pulley shaft, relates in particular to a kind of CVT automatic transmission V-type belt shaft blank.
Background technique
Belt shaft is a kind of driving mechanism, and driving belt pulley shaft coordinates with driving pulley, controls two and regulates effective transmission circumference with the spacing between wheel face, thereby reach the object of regulation output ratio by hydraulic oil.CVT gearbox is exactly there is no clearly concrete gear, similar automatic transmission case in operation, but the variation of speed ratio is but different from the trip stop process of automatic transmission case, but continuous, so power transmission is lasting and smooth and easy.V-type belt shaft is that CVT gearbox is used for transmitting motion and turning round short mechanical key parts, and its inherent quality and precision directly affect the total quality of gearbox.The general production technology of manufacturing firm: the moulding → heat treatment → machine cut of freely pull out → local upsetting of blanking → heating (1100～1150 ℃) → pneumatic hammer is Gear shape process one by one, this production technology course of working is complicated, machine tool drops into more, effect is very low, manufacture cycle is longer, cutting has been wasted metallic material, and cost of production is high, and difficult quality guarantee.China Intellectual Property Office discloses CN201110416697.7 driving belt pulley shaft, it mainly comprises input end and band wheel face, input end is arranged on the rear portion with wheel face, front portion with wheel face is belt wheel construction section, the front portion of belt wheel construction section is belt wheel control section, and the diameter of belt wheel construction section is greater than belt wheel control section, and is evenly equipped with oil circuit mouth on the end face of belt wheel construction section, in belt wheel control section, be provided with and oil circuit groove, the position of described oil circuit groove coordinates with the position of oil circuit mouth.It is arranged on oil circuit mouth on the end face of belt wheel construction section, thereby has reduced the length of belt wheel control section, and then has reduced the length of whole driving belt pulley shaft.Manufacturing firm all adopts inner chamber precision forging blank technology both at home and abroad at present, can meet required precision like this, has reduced again manufacture cost and cycle, also meets the trend of world today's development of manufacturing simultaneously.
Summary of the invention
The utility model provides a kind of less investment, efficiency high, adopts warm cold closed-die forging composite forming technology, can meet required precision, has reduced again manufacture cost, also meets the CVT automatic transmission V-type belt shaft fine forge piece of world today's development of manufacturing trend simultaneously.
The utility model is realized by following technical solution:
CVT automatic transmission V-type belt shaft fine forge piece, comprise input end, belt wheel and shank, described input end is arranged on the lower end of belt wheel, described input end is frustum cone structure, the angle with wheel face and horizontal plane formation of described belt wheel is 11 °, and the another side of the described peripheral belt wheel of input end is provided with the round bump with external tooth; The upper end of described belt wheel is the taper off cylindrical shank of trend of external diameter; Described fine forge piece is overall structure.
Described input end is two frustum cone structures that conicity is different.
Described input end is that round platform connects round column structure outward.
Described shank is taper off three sections of cylinders and the changeover portion between them of trend of external diameter.
The utility model compared with prior art has following beneficial effect:
The utility model is overall structure; adopt warm cold closed-die forging composite forming technology; reduced and adopted the more problem of machine tooling flank of tooth equipment investment, with short production cycle, manufacturing efficiency is high; constant product quality, yield rate is high, intensity is large, density is high, shock resistance; save resource, protected environment, can meet required precision; reduce again manufacture cost, also met the trend of world today's development of manufacturing simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the worm's eye view of Fig. 1.
Sequence number in figure: 1, input end, 2, belt wheel, 3, shank, 4, band wheel face, 5, round bump.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in Fig. 1, Fig. 2, a kind of CVT automatic transmission V-type belt shaft fine forge piece, comprises input end 1, belt wheel 2 and shank 3, and described fine forge piece is overall structure; Described input end 1 is arranged on the lower end of belt wheel 2, described input end 1 connects round column structure outward for round platform, the angle with wheel face 4 and horizontal plane formation of described belt wheel 2 is 11 °, and the another side of the described peripheral belt wheel 2 of input end 1 is provided with the round bump 5 with external tooth; The upper end of described belt wheel 2 is shank 3, and described shank 3 is external diameter taper off three sections of cylinders and the changeover portion between them of trend.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not form the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model, above scheme being done that does not depart from technical solutions of the utility model, within all still belonging to the utility model protection domain.
