Wiwọn pẹlu irin-iṣẹ wiwọn kan

•Lilo ẹrọ wiwọn jiaPipa The gear is fixed on the measuring machine, and through precision sensors and measurement systems, the machine can directly obtain data such as the tooth profile, pitch, and helix angle of the gear. Nipa itupalẹ data wọnyi, module ti jia le ṣe iṣiro. This method is highly accurate and suitable for measuring gears with high precision requirements, but the equipment is expensive and requires professional operation.

•Lilo awọn ohun elo obe jia: Caiper Verneer cather le ṣe iwọn sisanra ti a fi iwọn ati addedum shordenm ti awọn eyin jia. Fun dea kan boṣewa kan, ibasepọ kan wa laarin module, sisanra aladun, ati addeddum chipal. By measuring the chordal thickness and chordal addendum of the gear teeth and referring to the relevant gear parameter calculation formula, the module of the gear can be calculated. Ise deede ti ọna yii jẹ ga pupọ ati pe o dara fun wiwọn aaye lori iwọn piars igbagbogbo.

Iṣiro da lori awọn aye ti a mọ

•Iṣiro lati nọmba eyin ati ni iwọn iwọn ila opin: Ti nọmba eyin ati iwọn ila opin Pitch ti jia ni a mọ, module le ṣe iṣiro nipa lilo agbekalẹ.

•Iṣiro lati aaye aarin ati ipin gbigbe: In a gear transmission system, if the center distance between the two gears and the transmission ratio are known, and the number of teeth and of the two gears satisfy the relationship , and the center distance . Nipa apapọ awọn idogba wọnyi, module le ṣe iṣiro.

Lafiwe pẹlu jia boṣewa

•Afiwera jakejado: Yan jia boṣewa kan pẹlu iṣu ti o mọ ati afiwe rẹ pẹlu jia lati ni iwọn. By observing the size of the gear teeth and making a rough comparison, an approximate value of the module of the gear to be measured can be estimated. Ọna yii rọrun ati iyara ṣugbọn ni deede kekere ati pe o dara fun idajọ aiwujọ nikan.

•Ifiwewe Agbara: Gbe jia boṣewa ati jia lati ṣe iwọn papọ ki o ṣe akiyesi ìyí ti deede ti awọn profaili ehin nipasẹ over wọn. Ti o ba ṣeeṣe, o tun le lo projector lati ṣe agbese awọn profaili ehin ti awọn earé meji wa si oju-iwe. By adjusting the position and angle, find the standard gear that best matches the gear to be measured, and the module of the standard gear is the approximate module of the gear to be measured.
