Abstract

The present invention relates to a method for removing drive gap in heavy-load gearbox and elastic deformation. Said method includes the following steps: using the motor drive current before last operation stop as basis and using it as initial pretorque current for present start, and applying it to motor, starting working brake, converting the pretorque current into the pretorque current required for present operation according to a certain conversion rate, starting safety brake, the motor can be acceleratively started and operated so as to implement present start.

Description

technical field [0001] The invention relates to a method for eliminating transmission clearance and torsional elastic deformation of a transmission gear box of a ship lift lifting system of a navigation facility in a water conservancy and hydropower project. Background technique [0002] The transmission mechanism of the lifting system of the ship lift is as follows: electric motor, working brake, high-speed input shaft of reduction gearbox, reduction gearbox, low-speed output shaft of reduction gearbox, safety brake, and drum mechanical connection. A balance weight and a water-filled ship's box are respectively hung on both sides of the reel by wire ropes. Since the water depth in the ship-carrying box will change after each time the ship-carrying box rises and falls alternately to change the running direction, on both sides of the reel, sometimes the ship-carrying box side is heavier, sometimes the balance weight side is heavier, and sometimes the two...
