STRAND LAYING HEAD MAIN SHAFT COMPONENT, STRAND LAYING HEAD, AND METHOD FOR BALANCING DYNAMIC IMBALANCE IN STRAND LAYING HEAD

摘要

A method for balancing a dynamic imbalance in a strand laying head, a strand laying head main shaft component, and a strand laying head. The strand laying head main shaft component comprises a main shaft (1) and a strand laying tube (2) fixed on the main shaft. A strand laying tube balancing block (3) for balancing eccentric quality of the strand laying tube is disposed on the strand laying head main shaft. The strand laying head comprises a case body (8), a motor (9), a driving bevel gear (11) connected to a motor rotor through a coupling, and a driven bevel gear (12) fixed on the main shaft. The driven bevel gear meshes with the driving bevel gear, and the main shaft is installed on the case body through a bearing. The strand laying head has small vibrations during work, can increase the rotating speed of a main shaft of the strand laying head, lower a failure rate of the strand laying head, and increase a service life of the strand laying head.
