Abstract

The invention belongs to the technical field of mechanical processing, and particularly relates to a grouping method for measurement of angular difference of a common planetary gear. The method provided by the invention obtains a grouping method for measurement of the angular difference based on the radial variation conversion of the measured amount of balls by comparing the principle of measurement. The method can complete the problem of grouping the measurement of the angular difference of the common planetary gear by using a simple measuring tool. The invention directly uses a reference specified by part drawings to perform the measurement without the need of reference conversion, has high measuring precision, fast speed and no additional skill requirements for the inspection and measurement personnel, and is convenient and quick. The method provided by the invention can be used to avoid the repeated matching and trial installation during the assembly of the device, ensure the uniform load of the common planetary gear and improve the operating life of the device.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a method for measuring and grouping angular differences of common planetary gears. Background technique [0002] Common planetary gear refers to a special gear shaft in which two gears on one gear shaft act as planetary gears of two different planetary mechanisms at the same time in the device. Due to the functional requirements of the device, the two gears on the gear shaft are generally designed as a spur gear and a helical gear, and the two gears on a group of common planetary gears (shafts) in the same device need to have the same angle. Otherwise, the gear shaft will be damaged in advance due to the excessive load of a single gear, or the assembly interference will be caused due to the large angular difference difference, making the device unable to complete the assembly. [0003] For the angular difference measurement grouping of common planetary gears, the m...
