Overview of gear comprehensive tester

gear composite error (gear composite error products mainly include disposable plastic tableware, sauce bottles and other hotel supplies, plastic kettles and other teste landfilling. The cost of sanitary landfilling and sanitary combustion should be very high R)

a length measuring tool for measuring the gear accuracy by using the double-sided meshing method while doing the breaking experiment or the single-sided meshing method (see gear measurement). The comprehensive gear inspection instrument is divided into two types: double-sided meshing inspection instrument and single-sided meshing inspection instrument

Unless there is a special need,

gear double-sided meshing tester is referred to as double meshing tester for short, which is used to measure the radial comprehensive error and the change of gear pair center distance. For the shape of this tester. Under the action of spring force, the measuring gear makes double-sided meshing transmission with the measured gear wheel, and the single errors such as the radial runout of the gear ring and the tooth shape error of the latter are comprehensively reflected as the radial variable momentum parallel to the guide rail. The value is indicated by the dial indicator or the error curve is recorded by the recorder. The maximum variation of the measured gear in one rotation and one rotation tooth is the radial comprehensive error and the radial one tooth comprehensive error respectively; The maximum variation measured by a pair of tested gears is the variation of gear pair center distance. The double meshing instrument has simple structure and high measurement efficiency. It is widely used in mass production to test gears with accuracy below grade 7

gear single side meshing tester is abbreviated as single meshing tester, which is used to measure the tangential comprehensive error, etc. Single meshing instrument can be divided into grating type, magnetic grating type and inertia type. It is a grating type gear single side meshing tester. When the measured gear drives the measured gear to rotate, the angle error caused by the combination of single errors such as the circumferential pitch, tooth shape, tooth direction and radial runout of the measured gear is converted into an electrical signal output through a circular grating sensor installed coaxially with the measured gear

this electrical signal is compared with the electrical signal output by the circular grating sensor installed coaxially on the measuring gear after amplification, sorting and frequency division, and then the error curve is recorded by the recorder. This kind of gear inspection instrument is generally used to measure gears with 5 ~ 6 levels of accuracy, and higher accuracy can be achieved during paired measurement
