Slewing bearing with external gear, ZZ's single volleyball series slewing ring bearing has a rectangular cross section, which is the most common in daily life, and has the characteristics of high stability and high cost performance. Widely used in construction machinery, construction machinery, ship machinery and other fields, the single volleyball series slewing bearings provide a variety of solutions for medium to heavy applications.
ZZ's worm gear and worm rotary drive includes two categories: cylindrical worm and envelope worm, of which cylindrical worm is suitable for medium speed. Heavy-duty applications while the enveloping worm is suitable for low-speed heavy-duty and high-precision applications, the worm gear and worm rotary drive can be self-locking, in the power movement The domain can provide basic security and further simplify the overall design of the equipment, and is an excellent industrial accessory.
Rotary drive can be divided into gear drive and worm gear drive according to different transmission forms. It can be divided into two types: open type and closed type. The simplest form of rotary drive is the drive turntable applied to construction machinery products such as excavators and tower cranes. As the last link of the deceleration transmission chain, this rotary drive is open. The front end needs to be equipped with a planetary reducer with a large reduction ratio as its power input, so it can only be called the prototype of the rotary drive. In order to expand the application range of such products and further improve the convenience of product use and maintenance In order to further improve the driving ability of the product, the enveloping worm drive has also been applied to such products. The slewing drive equipped with the enveloping worm not only increases the driving torque, but also The drive accuracy has also been further improved, and digital control is possible, so it is widely used in tracking and fine-tuning devices on solar and wind power generation equipment, in addition to robots, radar, low-speed heavy-duty lifting, lifting equipment, precision CNC turntables and other product fields All have good application effects.
The excavator slewing bearing is used very frequently, bears comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time.The excavator slewing bearing is an important component in the excavator structure and plays a very critical role. It is located between the excavator's upper structure (called the rotary table) and the bottom structure, allowing the excavator's upper structure to rotate 360 degrees, allowing the excavator to operate the full range of the work area.
High speeds, high loads and salty environment require strong and precise components. The ZZ slewing rings is the perfect answer to the offshore industry. Our specific design satisfy the main manufacturers of onboard and harbour cranes, winches, davits and rubber tired gantry cranes as well as propellers. We propose innovative solutions of sealing to completely protect the bearings from the environment. zz follows the international certification standards.
The ZZ slewing ring, a very robust mechanical part, is particularly adapted to these applications. Our process control gives the customer a very simple solution to set up the pinion and to save production time.
slewing bearing manufacturing process, china slewing ring gear, ZZ Slewing Bearing provide different kinds of surface treatment: Such as Zinc coating, Sand blast, Painting, oil protecting, barffing etc, which will guarantee the slewing bearing with long durability.
China Slewing Ring Bearing Manufacturers, Excavator Slewing Bearing, For the slewing ring manufacture, ZZ selects the best material specifications to suit most foreseen usages.These materials are manufactured by approved steel works.
Slewing ring turntable,Slewing ring bearing with external gear, High speeds, high loads and salty environment require strong and precise components. The ZZ slewing rings is the perfect answer to the offshore industry.
The miniature slewing bearing has higher precision and more flexible rotation. Generally, it is a gearless slewing bearing with a size of less than 200mm. It is used in industrial robots, experimental benches, food processing machinery, etc.
Crane slewing bearings, also known as slew bearings or slew bearings, are critical components in the design of cranes and other heavy machinery that require rotation about a central axis. The main function of the slewing bearing is to support the upper structure of the crane (such as the jib and cab) and make it rotate smoothly.
Compared with standard bearings, the ZZ slewing ring is a good solution to reduce the assembling time, to simplify the structure and to increase the capacity of the whole system. The high capacity of our gear is the result of our process control. Many towns around the world use our product every day to treat water. Our worldwide company structure gives strong support to customers and to end users.
