Generation of a crowned pinion tooth surface by a surface of revolution [PDF]

A method of generating crowned pinion tooth surfaces using a surface of revolution is developed. The crowned pinion meshes with a regular involute gear and has a prescribed parabolic type of transmission errors when the gears operate in the aligned mode.

RESEARCH ON GEAR TOOTH INTERFERENCE PROBLEM OF SINGLE DRIVE MULTI-POINT MESHING RACK AND PINION TRANSMISSION

Jixie qiangdu
The load capacity of the rack and pinion mechanism is limited by the contact strength of the gear tooth surface.In order to improve its load capacity,multiple pairs of gears and single rack meshing were adopted.In order to simplify the structure of the ...

Effect of geometry and operating conditions on spur gear system power loss [PDF]

The results of an analysis of the effects of spur gear size, pitch, width, and ratio on total mesh power loss for a wide range of speeds, torques, and oil viscosities are presented. The analysis uses simple algebraic expressions to determine gear sliding,
