Abstract
The invention provides a gear clearance measurement component based on a displacement sensor. The gear clearance measurement component comprises a measuring plate, a component substrate and two elastic positioning devices and a displacement sensor which are arranged on the component substrate, wherein the measuring plate is flexibly connected with the component substrate through a cantilever support shaft, the lower end of the measuring plate is fixedly connected with a measuring head, the two elastic positioning devices are close to the two sides of the measuring plate, and the displacement sensor is close to the upper end of the measuring plate. The gear clearance measurement component can measure the amount of swing according to the lever principle, which can be regard as a direct measurement of engaging clearance, and has the advantages of high measurement accuracy, fast measuring response speed and compact structure, so as to detect the engaging clearance of various gear clearance products easily.
Description
Technical field
The present invention relates to car transmissions technical field, be specifically related to a kind of gear clearance measurement components of deformation based sensor.
Background technology
In wheel box, main reducing gear assembling process, need to carry out back lash Survey control to some gears meshing positions, make its gap meet transmission requirement, ensure drive noise and transmission efficiency.
Generally adopt dial gauge manual measurement mode in current gear drive assembling process, also have in some advanced rigging equipments and use high-precision encoder automatically to measure.
For use dial gauge manual measurement mode, efficiency is lower, and precision is not high, for ± 0.02mm, and human factor is larger on measuring process impact.
For using the mode automatically measured of high-precision encoder, efficiency is higher, but complex structure and precision is not high, be commonly in the industry ± 0.03mm, cost is also higher.
