The gear grinding and modification method for the hot continuous rolling reducer gear comprises modification in the tooth length direction of the gear and modification in the tooth height direction of the gear, wherein the modification in the tooth length direction of the gear comprises tooth end slope reversing, and the modification in the tooth height direction of the gear comprises tooth top modification and tooth root modification. According to the method, a universal modification method for the hot continuous rolling reducer gear is provided, complex computation of gear modification is avoided, and the modification efficiency of the hot continuous rolling reducer gear is improved.

Description

technical field [0001] The invention relates to the technical field of gear modification, in particular to a gear grinding modification method for a hot continuous rolling reducer. Background technique [0002] The gear of the hot rolling reducer is a heavy-duty gear, and it is required that the contact spot of the gear after assembly is not less than 50% of the tooth height and not less than 70% of the tooth length. Affected by factors such as the machining accuracy of the box, the accuracy of the gear grinding machine tool, the wear of the diamond wheel and the grinding wheel, the axial deflection of the gear after assembly, the internal and external circular deflection of the bearing, and the gap error, the hard-toothed gear and the The gear shaft is assembled after being ground according to the parameters in the drawing, and interference between the tooth top and the dedendum often occurs, causing the tooth height and tooth length contact to fail to meet the requirements...

Problems solved by technology

Affected by factors such as the machining accuracy of the box, the accuracy of the gear grinding machine tool, the wear of the diamond wheel and the grinding wheel, the axial deflection of the gear after assembly, the internal and external circular deflection of the bearing, and the gap error, the hard-toothed gear and the The gear shaft is assembled after being ground according to the parameters in the drawing, and interference between the tooth top and the tooth root often occurs, resulting in tooth height and tooth length contact not meeting the requirements of the drawing, so the gear of the reducer needs to be modified before assembly

Although each gear is affected by factors such as the machining accuracy of the box, the precision of the gear grinding machine, the wear of the diamond wheel, and the grinding wheel, in mechanical processing, the machining accuracy of the box, the accuracy of the machine tool of the gear grinding machine, the wear of the diamond wheel, and the grinding wheel , The axial deflection of the gear after assembly, the internal and external circular deflection of the bearing and the gap error change within a certain reasonable range. If the special gear modification calculation formula or special software for modification is used to calculate the modification data, it will be complicated and time-consuming. not necessarily practical
