Description
Technical field
The utility model belongs to the mechanical transmissioning technology field, is specifically related to a kind of outer gearing round pin formula silent chain transmission system.
Background technique
Silent chain is a kind of widely used important mechanical transmission basic part, particularly under the operating mode of high speed, heavy duty, low noise and big centre distance, its transmission performance is better than toothed belt transmission, gear transmission and roller chain drives, has become one of type of belt drive of numerous industry first-selections.Owing to lack necessary theory support and technical support, the domestic ability that does not still possess independent research New Silent Chain series product at present is in the passive situation that relies on external high price import New Silent Chain series product always.
At present, at the round pin formula silent chain transmission system that transmission field is used widely, existing outer gearing silent chain also has interior engaging tooth shape chain.Interior engaging tooth shape chain contacts with sprocket tooth with the inboard flank profil of work carrier bar, and the location is unstable, and it is more serious to wear and tear, and the life-span is short.Rolling pin formula silent chain has and switches political loyalty apart from function, can reduce polygon effect and the transversal wave movement of system, but amount of parts is more, and the processing technology complexity.In order to improve the degree of finish of chain plate hole contact area, existing silent chain carrier bar is generally thinner, and bear big load just needs to increase chain row number, makes component number increase sheet type complexity.
Existing Chinese patent CN101761606A is also about silent chain, but its related be a kind ofly to compare round pin formula silent chain with it and be easy to more make by singly rolling pin realize the switching political loyalty silencing chain of distance, reduced processing cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of revolution fatigue strength that can improve carrier bar, prolongs carrier bar working life, strengthens the outer gearing round pin formula silent chain system of system reliability.
For solving the problems of the technologies described above the technological scheme that adopts be:
A kind of outer gearing round pin formula silent chain transmission system mainly is made up of outer gearing round pin formula silent chain 1, drive sprocket 2 and driven sprocket 3.
Described outer gearing round pin formula silent chain 1 is made up of work carrier bar 10, bearing pin 11 and guide card 12, and a bearing pin 11 passes the chain plate hole of carrier bar 10, and two adjacent row's carrier bars 10 are coupled together, and the two ends of bearing pin 11 exceed outermost chain plate hole certain altitude; The profile in the guide card hole of described guide card 12 is identical with the profile of bearing pin 11, and guide card 12 just in time is fixed in the external part of two adjacent bearing pins 11; Work carrier bar 10 is staggered in modes such as 6 * 5,7 * 6,8 * 7, will arrange carrier bar 10 by bearing pin 11 and guide card 12 to join end to end more, thereby form many rows Transmitted chains of sealing.
Described drive sprocket 2 and driven sprocket 3 adopt involute profile.The number of teeth of drive sprocket 2 is 21, and the number of teeth of driven sprocket 3 is 25.Endoporus is involute splines, by the transmission of power between spline realization sprocket wheel and motor shaft and the gear-box axle.
The beneficial effects of the utility model are:
Adopt outer gearing round pin formula silent chain to realize transmission of power, silent chain silent chain thickness more in the past increases, thereby tired revolving strength and the fatigue life of improving carrier bar improves system reliability; Along with thickness of link plates increases, under the prerequisite that guarantees chain intensity, reduced carrier bar row number, reduced the number of component in the chaining bar, make that chain is easy to install, reduced installation cost.Along with improving constantly of dieing machine technology, can realize the highi degree of accuracy stamping-out processing of the part that thickness is bigger, can guarantee the degree of finish of chain plate hole contact area, reduce the generation of tear-strap.
In addition, this transmission system does not need tension device, and is simple and compact for structure, can realize the transmission of power of positive and negative both direction, the outer gearing positioning stablity.
