Abstract
The utility model provides a motorcycle sprocket, working section profile of tooth is involute curve, and involute curve's main parameter is: the meshing pressure angle alpha is 28-32 degrees; involute initial flare angle delta10 to 10 degrees; involute end flare angle delta216-26 °; and the arc R at the transition of the involute curve and the tooth crest part and the tooth root part is 0.8-1.2 mm. The utility model is used for motorcycle transmission system, because profile of tooth curve key parameter design science, reasonable, standard, the process that the chain cut into the sprocket is in the line contact state all the time, eliminates sliding friction between them, and the transmission is steady, reduces the vibration, reduces the transmission noise, is favorable to environmental protection.
Description
Technical field
The utility model relates to a kind of driving chain wheel, particularly motor bike profile of tooth sprocket wheel.
Background technology
The transmission of power of motor bike generally adopts the sprocket wheel chain gear at present, and for reducing noise, used sprocket wheel changes the profile of tooth sprocket wheel into by roller chain wheel.Existing motor bike is not sought unity of standard with the profile of tooth sprocket wheel, and its tooth curve principal parameter is unreasonable, lack of standardization, and the equal disunity of domestic each originating firm causes the noise of motor bike driving system bigger, causes environmental pollution.
The utility model content
The technical problems to be solved in the utility model is to overcome the weak point of existing motor bike with the profile of tooth sprocket wheel, provides a kind of transmission noise little, helps the chain wheel of motorcycle of environmental protection.
The technical solution of the utility model is: sprocket wheel active section profile of tooth is an involute curve, and improvements are that the principal parameter of involute curve is: intermeshing pressure angle α=28 °～32 °; The initial angle of spread δ of involute
1=0 °～10 °; Involute stops angle of spread δ
2=16 °～26 °.
Above-mentioned involute curve and tooth top partial sum tooth root part rounding off, the transition position circular arc R is 0.8～1.2mm.
Adopt above technical scheme; because sprocket tooth form curve principal parameter has been carried out improving design; more science, rationally, standard; the process of chain incision sprocket wheel is in the line contact condition all the time in the sprocket wheel of motor bike, chain transmission system; cliding friction when having eliminated chain incision sprocket wheel becomes steadily whole transmission process, reduces the vibration of messenger chain to greatest extent; reduce the transmission noise, help environmental protection.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is an A place partial enlarged drawing among Fig. 1;
Fig. 3 is the utility model active section involute curve principal parameter scheme drawing.
The specific embodiment
As figure, the utility model embodiment is made of sprocket body 1 and sprocket tooth part 2, and tooth portion active section is an involute curve 3.This involute curve is described below: involute 3 is a basic circle with round surely 4, and its principal parameter is intermeshing pressure angle α=30 °; The initial angle of spread δ of involute
1=2 °; Involute stops angle of spread δ
2=22 °.Involute curve and tooth top partial sum tooth root part transition arc R are 1mm.
Claims (2)
1, a kind of chain wheel of motorcycle, the active section profile of tooth is an involute curve, it is characterized in that the principal parameter of involute curve is: intermeshing pressure angle α=28 °～32 °; The initial angle of spread δ of involute
1=0 °～10 °; Involute stops angle of spread δ
2=16 °～26 °.
2, by the described chain wheel of motorcycle of claim 1, it is characterized in that described involute curve and tooth top partial sum tooth root part rounding off, the transition position circular arc R is 0.8～1.2mm.
