Gear double-face engagement precise detection device

Abstract

The invention relates to a gear double-face engagement precise detection device. For a common double-engagement instrument, a handwheel is shaken to enable a leading screw to rotate to drive a slide block to do longitudinal movement on a linear guide rail on a support for engagement and separation of a detected gear and a standard gear, the structure is complex, and the cost is relatively high. The gear double-face engagement precise detection device comprises a support, wherein the support is provided with a measuring assembly, a detected assembly, a position adjusting device and a measuring assembly. The gear double-face engagement precise detection device is characterized in that the detected assembly comprises a swinging shaft and a swinging frame arranged on the swinging shaft horizontally, the position adjusting device comprises a compaction spring, a cam with a handle and a mobile board, the mobile board is movably arranged on the support, the compaction spring and the cam with the handle are mounted in mounting holes of the mobile board, the measuring assemblies comprise displacement sensors arranged on the mobile board, and axial lines of the displacement sensors are perpendicular to the swinging frame. The gear double-face engagement precise detection device has a simple structure, is simple and convenient to operate and is suitable for mass detection and quality control in a gear production field and a detection center.

Description

technical field [0001] The invention relates to the field of gear detection devices, in particular to a gear double-sided meshing precision detection device. Background technique [0002] Gear quality is one of the key factors affecting the performance of the machine. The gear transmission process mainly has three requirements: the accuracy of the transmission motion, the smoothness of the transmission (noise and vibration), and the uniformity of the load distribution (life). Due to reasons such as manufacturing and installation, there are always various errors in actual gears. These errors directly affect the accuracy and dynamic characteristics (especially vibration and noise) of the transmission system. Therefore, how to measure, analyze and control gears Errors are very realistic. [0003] Gear measurement is mainly divided into three categories: analytical measurement based on tooth profile measurement, helical line measurement and tooth pitch measurement, functional ...

Problems solved by technology

Because there is always friction between the slide table and the guide rail of the instrument, and because the slide table is heavy, the friction resistance generated when it slides on the guide rail is large, so the measurement sensitivity is not high and the measurement accuracy is low

[0007]At the same time, in order to make the gear under test mesh and separate from the standard gear, the ordinary double-mesh instrument drives the slider along the shaft fixed on the machine base by shaking the handwheel to turn the lead screw. The linear guide rail moves vertically, the structure of the whole machine is complex and the cost is high

Especially when disassembling and assembling the workpiece, the operation is inconvenient and the efficiency is low
