Study on the measurement of gear helix position deviation by double flank rolling gear tester;

Computer Estimating for the Errors of Tooth Profile and Helix of Transmission Gears;

This paper is based on the features of tooth profile and helix tolerance zone of transmission gears.

The tooth profile error and longitudinal form error are calculated,and the change rule with setting angle of them is got.

The features of involute gear profile are mapping analyzed, the principle and method of on machine measuring the longitudinal form error of bull gears with the rack probe is introduced, the data evaluation model of longitudinal form error is established, and a measuring example is given.

With Pro/E and ANSYS,find the extremum of the main errors(site error and longitudinal form error of the gear) that influence the reliability of the whole mechanism and define reasonable tolerance so as to not only decrea.

Wedge locking device and unidirectional ratchet device are mainly used abroad and wedge lock device is mainly applied in China.

This paper develops a mathematical model for the solution to the longitudinal tooth curve of an internal gear shaver based on the simplified principle for space transmission of a helical gear pair without flank clearance,and proposes a calculating approach of the profile modification of the grinding wheel to be used for grinding the longitudinal tooth curve of the shaver.

Experimental research on tooth trace error resulting from differential change gears of hobbing machine;

The authors explained a method of contact induction hardening for vehicle steering gear racks,which was based on the experience of actual production and experiment.
