In the family of elevator, screw lift, with its small size, high transmission efficiency, speed range is wide, many advantages of high precision and is widely used in servo, stepper, dc transmission system. Its function is to reduce the speed increase torque and reduce the inertia ratio of the load/motor under the premise of ensuring the precision transmission. Some users in the use of the gear screw elevator, due to the illegal installation and other human factors, and the output shaft of the screw elevator broke, causing the enterprise to incur unnecessary losses. Therefore, in order to better help the majority of users to use the screw elevator, we will introduce you in detail how to correctly install the gear screw elevator.
The correct installation, use and maintenance of the gear screw elevator is an important link to ensure the normal operation of mechanical equipment. Therefore, when installing the screw elevator, please strictly follow the following installation instructions and carefully assemble and use them. Connect the motor with the screw elevator. When connecting, it is necessary to ensure that the output shaft of the screw elevator is consistent with the input shaft of the motor, and the outer flange is parallel. If the concentricity is inconsistent, it will cause the motor shaft to break or the gear wear of the screw lift.
In addition, when installing, it is strictly forbidden to use the hammer and other blows to prevent the axial force or radial force from damaging the bearing or gear. Be sure to tighten the mounting bolts before tightening the bolts. Before installation, clean the anti-rust oil in the connection part of the motor input shaft, positioning lug and screw lift. The purpose is to ensure that the connection is tight and flexible and prevents unnecessary wear and tear.
Before connecting the motor and the screw elevator, the motor shaft seat should be perpendicular to the tightening bolt. In order to ensure uniform force, the installation bolt of any diagonal position will be rotated first, but do not tighten, and then screw the two mounting bolts on the other two diagonal positions to tighten the four mounting bolts one by one. Finally, tighten the bolts. All tightening bolts shall be fixed and checked by the torque wrench with the fixed torque data marked.
The correct installation between the screw elevator and the mechanical equipment is the correct installation between the screw elevator and the drive motor. The key is to ensure that the output shaft of the screw elevator is consistent with the drive part axis.
The spiral elevator helps the old building to revitalize the new wind.
Six historical building to be put into use, the activation program participants by using spiral elevator upgraded to the site and the integration of modern commercial civilization, citizens to a happy place to be.
Old buildings are not to be "static", but to "activate", old buildings to add new aesthetic elements. Such as "H" the beauty of the lotus building, connection of two main parts due to disrepair building need to remove, so "H" the old-fashioned LouWu modelling to be shattered, red, yellow, blue, such as bold, fashion color and to repair its "dive" want. Lui seng chun is next to the building build building, provide the bathroom and stairs, adding spiral elevator, convenient for disabled people up and down in the future, and the "gap" building the balcony also is put on the aluminium alloy window fashion. They are modified to fit the contemporary urban environment and integrate contemporary aesthetics and contemporary trends.
Former Hong Kong chief executive Donald tsang in savannah college of art and design completion at Hong Kong convention speech, is also a final review: "in recent years, we are very pay attention to protect the traditional buildings in Hong Kong, inheritance and revitalization of the old house, that they can continue to benefit in the future, by DaiChuanCheng, keep the diversity of our city, it is a huge investment, is also the performance of the Hong Kong cultural values are value-added."
