Abstract
A gearset for a gear spindle coupling or the like, and method for forming the same, comprising a sleeve gear and a hub gear which may be ground after surface hardening without the introduction of undesired structural weakening. The sleeve gear includes internal gear teeth and the hub gear includes external gear teeth in mesh with the sleeve gear teeth. Each internal sleeve gear tooth has an internal profile with the tooth height ranging from about 1.9 to about 2.2 divided by the diametral pitch of the sleeve gear, and each external hub gear tooth has a contact height less than the full tooth height. The contact height of the external tooth ranges from about 1.4 to about 1.6 divided by the diametral pitch of the hub gear, with the hub gear tooth region ranging between about 1.4/diametral pitch to about 1.6/diametral pitch. The whole depth of each external gear tooth ranges between about 1.5/diametral pitch to about 1.8/diametral pitch, and the whole depth of each internal gear tooth ranges between about 1.9/diametral pitch to about 2.2/diametral pitch to provide sufficient clearance between the tips of the external gear teeth and the roots of the internal gear teeth, and between the…
