The speed of the speed reducer is equal to the input speed of the worm gear divided by the reduction ratio of the worm gear, and then multiplied by the pitch of the lifting screw. Because of its structure, this kind of screw jack article from: the general use of grease lubrication, part of the series has a lubricant lubrication, than the grease lubrication of the series has a longer life, the advantages of stable work.
Over the years, the worm gear screw jack article from: widely used in machinery, metallurgy, water conservancy, chemical industry, medical, cultural, health and other industries, ARA spiral bevel gear box, has a compact structure, small size, light weight, easy to install, flexible, reliable, high stability, long service life, etc., can be driven directly by an electric motor or other power, also can be It can be driven by electric motor or other power directly or manually. This series of worm gear screw elevator can be self-locking. There are different structural types and assembly methods, and the lifting height is manufactured according to the requirements of users. I know there is a Shanghai Berman is still good , you can go to ask
