Processing principle

The principle of cold rolling the involute spline with small modulus on the wire rolling machine. LNR is a pair of involute rolling wheels with the same parameters, which are installed on the two main axes of the wire rolling machine respectively. The R wheel can be driven by the cylinder to carry out radial feed motion, and the L wheel can be adjusted by adjusting the mechanism to coincide with the indentation of the R wheel on the P surface of the workpiece. The workpiece P is clamped by two central holes, and the adjusting fixture can make the workpiece move in the axial direction, and swing a Φ angle around the axis parallel to the spindle of the machine tool around the O point of the fixture when it is subjected to force. To ensure that the workpiece is always in the free rolling state with the two rolling wheels during cold rolling It is convenient to clip the workpiece. 

The structural dimensions, shape and position tolerances and technical requirements of the rolling wheel are formulated according to the measurement of the wire roller and the cylindrical gear. The normal line length or span distance M of the rolling wheel is calculated according to the spline data of the gear worker, and the required material can be selected as Cr12MoV (hardness 59~62HRC).
