A measuring test platform and measuring method for gear dynamic/static meshing stiffness

Abstract

The invention discloses a test platform for measuring the dynamic / static meshing stiffness of gears. The shaft angle between the first test gear and the second test gear can be adjusted by rotating the disc seat, and can be adjusted by pushing the first bracket to slide along the slide rail. The center distance between the first test gear and the second test gear is good, which can be applied to the measurement of various external gears. The rotation position of the first test gear can be fixed by the second rotation locking mechanism, and then the rotation position of the force applying lever on the second test gear can be fixed by the rotation locking structure, and a counterweight is applied to the force application lever, which is static meshing The measurement of stiffness provides a test platform; in addition, the output load power mechanism can also provide load torque to the second test gear through the second rotating shaft, and then the input drive power mechanism can provide input power torque to the first test gear through the first rotating shaft, for dynamic The measurement of meshing stiffness provides a test platform, which has the function of measuring static meshing stiffness and dynamic meshing stiffness.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering design and gear transmission testing, in particular to a measurement test platform and a measurement method for dynamic / static meshing stiffness of gears. Background technique [0002] The vibration, shock and noise characteristics of the gear system are the focus of high-performance gear transmission. The change of the meshing stiffness is one of the main factors that cause the vibration, shock and noise of the gear system. The meshing between the gears is divided into static and dynamic. Static meshing means that the gears do not rotate relative to each other, while dynamic meshing means that the gears rotate relative to each other. However, the devices currently used for gear meshing stiffness tests are generally aimed at a single gear type and can only be used for dynamic meshing or static meshing alone. For example, the device and method disclosed in the invention patent "Stati...

[0002] The vibration, shock and noise characteristics of the gear system are the focus of high-performance gear transmission. The change of the meshing stiffness is one of the main factors that cause the vibration, shock and noise of the gear system. The meshing between the gears is divided into static and dynamic. Static meshing means that the gears do not rotate relative to each other, while dynamic meshing means that the gears rotate relative to each other. However, the devices currently used for gear meshing stiffness tests are generally aimed at a single gear type and can only be used for dynamic meshing or static meshing alone. For example, the device and method disclosed in the invention patent "Static measuring device and test method for meshing stiffness of cylindrical gears (application number: 201810705041.9)" are limited to the measurement of cylindrical gears and the measurement of static meshing stiffness; the invention patent "Meshing stiffness of gear teeth The device and method disclosed in "Measurement Test Device and Its Test Method (Application No. 201810395049.X)" are only used for the measurement of parallel axis gears and the measurement of static mesh stiffness. The existing measuring devices cannot have both static mesh stiffness and dynamic mesh stiffness. The measurement of the meshing stiffness has a single function and small applicability, and can only be used for the measurement of the meshing stiffness of a single gear
