Compared with straight bevel gears, spiral bevel gears have the following advantages. 1. The contact ratio is increased, that is, the overlap coefficient is increased. Because the tooth line of the spiral bevel gear is a curve, at least two or more teeth are in contact at the same...
Based on the generating principle of base circle involute, the tooth profile measurement method of involute gear is proposed ° The imaginary measurement of the pressure angle is the tangential contact of the rack (see Fig. 1), and the virtual single-sided meshing linear motion point scanning tooth profile measurement...
What are the characteristics of the straight bevel gear mechanism? Answer: 1) transfer the motion and power between two intersecting axes. 2) The gear distribution on the cone shrinks from the big end to the small end. 3) The large end face is the standard parameter face. 4) The...
Compared with cutting gear, precision forging gear has many advantages. Therefore, using precision forging technology to produce gear is the development trend of gear manufacturing industry. Because of its structural characteristics, the precision forging technology of spur bevel gear is the first to be used in production. At present,...
