Problems solved by technology

[0005] Looking at the existing gear meshing measurement devices, none of them use Gaussian filtering method to condition the signal, and the supporting measurement systems are relatively backward, which cannot meet the modern use requirements of fast and accurate measurement and intuitive display of results. It has become an urgent problem to be solved in the field of gear measurement

Embodiment Construction

[0050] Below in conjunction with accompanying drawing, the present invention will be further described:

[0051] 1. Mechanical device

[0052] In order to make the instrument have the function of measuring cylindrical gears and bevel gears, the present invention installs the standard gear and the measured gear on two horizontal parallel shaft systems, the schematic diagram is as follows figure 1 As shown in (a), when measuring bevel gears, one of the shaft systems needs to be rotated 90 degrees on the common plane (parallel to the horizontal plane) of the two shaft systems. The schematic diagram is shown in the attached figure 1 As shown in (b), since the shaft system rotates in the same horizontal plane, the center of gravity will not move up, which ensures the measurement accuracy of the bevel gear.

[0053] The mechanical device of the present invention is composed of a support, a servo mechanical system, a spindle system and a detection system. The support includes the b...

Abstract

The invention belongs to the technical field of gear measurement, and particularly relates to a gear single-sided meshing measurement device and method. In the present invention, the standard gear and the measured gear are respectively installed on two horizontal parallel shaft systems. When measuring bevel gears, one of the shaft systems needs to be rotated 90 degrees on the common plane (parallel to the horizontal plane) of the two shaft systems. The shaft system rotates in the same horizontal plane, so the center of gravity will not move up, which ensures the measurement accuracy of the bevel gear. And the tangential comprehensive deviation curve measured from the measuring device is processed by Gauss filter, which overcomes the defects of traditional filtering phase shift and complicated design. The invention has the advantages of wide application range and high measurement accuracy.

Description

technical field [0001] The invention belongs to the technical field of gear measurement, in particular to a gear single-side meshing measurement device and method. Background technique [0002] At present, there are two commonly used measurement methods for gears, the coordinate single measurement method and the meshing rolling comprehensive measurement method. The single-item error measurement technology adopts the coordinate-type single-item measurement method, and the gear is regarded as a geometric entity with a complex shape. On the established measurement coordinate system (rectangular coordinate system, polar coordinate system or cylindrical coordinate system), the gear is adjusted according to the design geometric parameters. The geometric deviation of the tooth flank is measured. The measured error item is the single geometric deviation of the gear, mainly three basic deviations such as tooth profile, tooth direction and tooth pitch. The comprehensive error measur...
