Abstract
The invention discloses the little number of teeth drive sprocket of a kind of high abrasion, the number of teeth of sprocket wheel is 15 teeth or 16 teeth, the pressure angle of drive sprocket involute profile is 30 °---33 °, the involute length that drive sprocket engages with silent chain work carrier bar is 0.52mm---1.26mm, and the modulus of drive sprocket involute profile is 1.989---2.021.The little number of teeth drive sprocket of high abrasion, by the new design to little number of teeth sprocket tooth form, changes sprocket tooth form parameter, increases sprocket wheel involute profile engagement area of contact, improves its transmission efficiency and wear-resisting property; And can pass through optimal design, the modulus of adjustment sprocket wheel involute profile and pressure angle, meet the demand of different main frame high-wear resistance in different operating situation.Experiment proves, high abrasion little number of teeth drive sprocket improves more than 5 times compared to common little number of teeth drive sprocket wear-resisting property.
Description
Technical field
The invention belongs to the profile of tooth sprocket wheel of system of vehicle transmission mechanism, be specifically related to the little number of teeth drive sprocket of a kind of high abrasion.
Background technique
Widely, silent chain transmission to be engaged with the profile of tooth of sprocket teeth by the profile of tooth of silent chain carrier bar to carry out transmission of power in the application of silent chain transmission in the high-speed drive such as automobile, motorcycle.In transmission process, the friction number of times due to the drive sprocket gear teeth is the twice of camshaft sprocket, and the area of contact of the drive sprocket gear teeth and carrier bar profile of tooth is little, thus drive sprocket gear teeth profile of tooth often serious wear, makes silent chain transmission wear out failure.At present, for improving the chaindriven wear-resisting property of profile of tooth, often through selection quality material, optimize heat treatment and processing method, manufacturing sprocket wheel, but, the involute engaged with carrier bar profile of tooth due to little number of teeth sprocket wheel is too short, area of contact is too little, and the sprocket wheel produced not only does not reach the wear-resisting property of needs, and cost is very high.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the object of the invention is to, provide a kind of high abrasion little number of teeth drive sprocket, cost is low, and wear-resisting property is strong, effectively avoids silent chain wear out failure, increases the service life.
The little number of teeth drive sprocket of high abrasion provided by the invention, the number of teeth of drive sprocket is 15 teeth or 16 teeth, the pressure angle of drive sprocket involute profile is 30 °---33 °, the involute length that drive sprocket engages with silent chain work carrier bar is 0.52mm---1.26mm, and the modulus of drive sprocket involute profile is 1.989---2.021.
The little number of teeth drive sprocket of described high abrasion, when the pressure angle of drive sprocket involute profile is 33 °, when the modulus of drive sprocket involute profile is 2.021, the involute length that described drive sprocket engages with silent chain work carrier bar is 1.12mm.
The little number of teeth drive sprocket of described high abrasion, when the pressure angle of drive sprocket involute profile is 30 °, when the modulus of drive sprocket involute profile is 1.989, the involute length that described drive sprocket engages with silent chain work carrier bar is 1.16mm.
The little number of teeth drive sprocket of described high abrasion, when the pressure angle of drive sprocket involute profile is 33 °, when the modulus of drive sprocket involute profile is 1.989, the involute length that described drive sprocket engages with silent chain work carrier bar is 1.26mm.
The little number of teeth drive sprocket of high abrasion provided by the invention, its beneficial effect is, by adjusting modulus and the pressure angle of little number of teeth drive sprocket involute profile, increasing sprocket wheel involute profile engagement area of contact, improve its transmission efficiency and wear-resisting property; And can optimal design be passed through, meet the demand of different main frame high-wear resistance in different operating situation.
