Abstract
The utility model discloses a kind of profile modifying gears, including gear, further include correction of the flank shape flank profil, and the width of tooth top is 1mm after correction of the flank shape, and the normal angle at two edges of tooth top is 90 degree, and the radius of the excessive circular at tooth top and edge is 0.2mm；Gear after correction of the flank shape, by test of many times, gear teeth meshing situation is improved, and noise and vibration mitigate significantly.
Description
Technical field
The utility model is related to a kind of profile modifying gears.
Background technology
The gear of Theoretical Design will appear the undesirable situation of gear teeth meshing in the application, cause to generate noise and vibration, institute
In order to obtain preferably transmission effect, often to do correction of the flank shape processing to gear in practice.
Utility model content
The purpose of this utility model seeks to provide a kind of profile modifying gear.
The utility model adopts the following technical solution：
A kind of profile modifying gear, including gear further include correction of the flank shape flank profil, and the width of tooth top is 1mm, two sides of tooth top after correction of the flank shape
The normal angle of edge is 90 degree, and the radius of the excessive circular at tooth top and edge is 0.2mm；
The program is used for gear compound graduation circular diameter 54mm, modulus 3, the gear of the number of teeth 18.
Gear after correction of the flank shape, by test of many times, gear teeth meshing situation is improved, and noise and vibration mitigate significantly.
Description of the drawings
Attached drawing 1 is the schematic diagram of the utility model；
Specific implementation mode
The utility model is described further in conjunction with the drawings and specific embodiments
In Fig. 1, the width of tooth top is 1mm after correction of the flank shape, and the normal angle at two edges of tooth top is 90 degree, tooth top and edge
The radius of excessive circular is 0.2mm.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
