Abstract
A toothing testing apparatus includes at least one pair of measuring disks or balls of a certain diameter which are introducible into respective substantially diametrically opposed tooth spaces of a testpiece, and measuring probes each including a base part and a measuring part elastically secured to the base part and rockable relative thereto, for measuring the distance between the measuring disks or balls of said at least one pair, the measuring part having one of the measuring disks or balls attached thereto and the base part being housed in or against a stationary part of the testing apparatus. The measuring disks or balls are symmetrically positioned and automatically centered in the tooth spaces to be measured, and the depth of penetration of the measuring disks or balls into the tooth spaces is measured by the testing apparatus.
Claims30
A toothing testing apparatus comprising:
- at least one pair of measuring members having a circular cross-section of a certain diameter arranged to be introduced into respective substantially diametrically opposed tooth spaces of a testpiece;
- a measuring probe for each of said measuring members, each measuring probe comprising a base part and a measuring part elastically secured to the base part and which is rockable in a rocking movement relative thereto, and arranged to measure the distance between the measuring members of said at least one pair, the measuring part of one of said measuring probes having one of the measuring members attached thereto and the base part of said one of said measuring probes being attached to a stationary part of the testing apparatus;
- means for symmetrically positioning and automatically centering the measuring members of said at least one pair in the tooth spaces to be measured;
- and means for electrically measuring a depth of penetration of the measuring members into the tooth spaces.
