1. What is a basic law of tooth profile meshing, what is the ratio of tooth profile meshing basic law? Basic tooth profile mesh
What is the function of law?
A: a pair of gears meshing transmission, the tooth profile at any one point contact, transmission ratio is equal to two rounds of defiled line by the common normal of the contact point is divided into two line segments, a rule known as the tooth profile meshing basic laws. If all the contact points of the tooth profile of common normal defiled line in the attachment, for the constant transmission ratio profile meshing basic law.
Role; With transmission ratio is a constant of tooth profile curve of the request.
2. What is a node, section lines, pitch circle? Nodes on the gear track is what is called circular gear?
Answer: the common normal of tooth profile contact and defiled the line of intersection is called nodes, a pair of tooth profile in gear meshing process node on the path is called pitch line, line section is called the pitch circle round. The pitch circle of gear for circular gear, or for non circular gears.
