The difference between wheel worm slewing drive and spur gear slewing drive

Worm gear slewing drive and spur gear slewing drive are both highly integrated modular rotary reducers. Users do not need to purchase individual parts one by one and then assemble them into products with worm gear slewing drive and spur gear slewing drive functions. Reduce unnecessary production preparation procedures, greatly improve production efficiency. In a […]

Introduction to the heat treatment process of double row ball slewing bearing

The double-row ball slewing bearing is called “mechanical joint” in the machinery industry. It is the primitive mechanical transmission necessary for relative rotation between two objects, and can bear axial force, radial force and overturning moment. Heat treatment of double-row ball slewing ring bearings and gears: The raceways of the double-row spherical slewing ring are […]

Instructions for Micro Sample Nucleic Acid Extraction Kit

The micro sample nucleic acid extraction kit is a kit specially used to extract DNA and RNA from various micro and trace samples. This kit uses a centrifugal adsorption column that can specifically bind nucleic acids and a unique buffer system. After the sample is lysed, the DNA is specifically bound to the silica gel […]

Nucleic acid extraction system application field

What are the types of tunnel construction equipment?

There are many commonly used tunnel construction equipment, such as tunnel lining trolleys, excavators, loaders, roadheaders, dump trucks, bulldozers, graders, concrete mixers, asphalt mixing plants, grab machines, conveyors, fans, and dust removal In addition, more advanced shield machines may also appear in tunnel construction. However, construction equipment is only a part. These construction equipment need […]

What is the difference between a worm gear reducer and a gear reducer?

Compared with the gear reducer, the worm gear reducer has a self-locking function. Worm gear reducers for lining trolleys are widely used in the mechanical field because of their self-locking function, such as tunnel lining trolleys, winches, packaging machines, printing machines, conveying equipment, and so on. However, it is also because of the frictional transmission […]
