Product Description

A screw jack, also known as a jackscrew, is a simple yet ingenious mechanical device designed to lift heavy loads or apply a controlled linear force by converting rotary motion into linear motion. It consists of a threaded screw mechanism enclosed within a housing, with a handle or crank for manual operation or a motor for powered use. Screw jacks find widespread application in various industries, especially in automotive, manufacturing and construction. Their versatility, reliability, and mechanical advantage make them indispensable tools for tasks requiring precise positioning and heavy lifting.

1. Installation Steps for Worm Gear Reducers
2. . Select the installation location: make sure that the installation location is dry, clean, and well ventilated, and take into account the convenience of maintenance and safety factors.
3. . Mounting foundation: place the reducer on the mounting foundation, check for leveling using a level, and make necessary adjustments.
4. . Axis alignment: Make sure that the input shaft of the reducer and the output shaft of the drive equipment maintain coaxiality to avoid wear and tear caused by axis misalignment.
5. . Connecting the motor: connect the gearhead to the motor and make sure the connection is tight and firm.
6. . Adjustment of position: adjust the position of the reducer to make it harmonize with other equipment.
7. . Test run: after the installation is completed, carry out a test run to check whether the reducer is running normally, whether there is abnormal noise and excessive high temperature.
