Comparison of slewing ring and spur gear slew drive used in truck crane

Truck with loading crane, referred to as truck crane, are a kind of lifting mechanism installed on a cargo truck for the purpose of loading or lifting goods. The lifting mechanism can be lifted up and down, expanded and rotated, the goods can be flexibly lifted and placed in a designated position.


The rotation of the lifting mechanism is realized on a slewing ring or a slew drive. The above picture shows a common lifting mechanism with slewing rings. The slewing ring with external gears is equipped with a yellow protective cover to protect the operator and at the same time to protect the equipment. Near the rotating mechanism in the picture, grease is flowing everywhere, quickly losing, the equipment is messy, the grease is contaminated and lost, resulting in frequent grease filling, high maintenance costs and high equipment failure rates.



The spur gear slew drive of U-TRSM can solve the above mentioned problems for customers.



Spur gear slew drive is also called gear type slew drive, it’s composed of slewing bearings, gears, housings, adapter flanges, support bearings, seals and other components. After reasonable design, component manufacturing, debugging, assembly and other processes, the products have the ability to withstand axial force, radial force, tilting moment torque and at the same time has a certain gear ratio, referred to as slewing drive. 



The structure of the spur gear slew drive determines that the spur gear slew drive has the characteristics of dustproof and waterproof, compact design, convenient installation and use, stability, reliability and low failure rate. It is very suitable for outdoor operation vehicles and can be used all-weather. 



The truck crane equipped with a spur gear slew drive keeps the equipment clean and new during use, has a low failure rate, no grease loss, not easy to be contaminated, low maintenance frequency, stable operation and long service life.In conclusion, 
the spur gear slew drive of the Unique Transmission is the best choice for customers to use outdoors.

What effect does the clearance of the slewing bearing have on the use？

Image
Clearance is an important technical parameter of slewing bearing , which directly affects the technical performance of the bearing's load distribution, vibration, noise, friction, temperature rise, service life and mechanical operation accuracy. Too large clearance will cause the bearing internal capacity area to decrease, the stress on the contact surface will increase, the rotation accuracy will decrease, the vibration and noise will increase. As a result, the service life is shortened and the clearance is too small, the negative clearance (interference) may occur in actual operation, rotation jamming will be inflexible, resulting in increased friction and heating, increased temperature rise, which will make the effective clearance smaller or larger, this vicious circle will cause the bearing to lock and cannot rotate. The bearing's clearance value is artificially specified by the designer and a certain range is divided according to the size of the slewing bearing, which is u...

What matters should be paid attention to when using slew drive？

Due to the slew drive is usually used as a general component of large scale equipment, therefore the slewing drive product is in a component assembly state when it is delivered to the user, it needs to be connected and assembled with the host when it is delivered to the complete machine manufacturer.In this process, especially for the closed structure slew drive, because the connection between the housing and the internal transmission part and the connection between the entire slewing drive and the host use the same set of connecting holes, so when the slewing drive leaves the factory, there is already a pre-connection between the housing and the internal transmission parts.   This connection involves the transmission clearance and position adjustment of the internal transmission parts of the slewing drive. Therefore, when connecting with the host, need to keep these pre-connections in the same set of flange holes. The other holes reserved by the manufacturer of the slew drive for...

These three factors should be considered when choosing a slewing bearing

Image
The service life of the slewing bearing is a general concern. In the selection and design stage of the slewing bearing, the service life of the slewing bearing can be obtained through theoretical calculations, but the theoretical service life is always not reached in practical applications, mainly analyze the ways to increase the life of the slewing bearing from three directions, selection design, installation and maintenance. Next, Unique Transmission will introduce the selection and design of the slewing bearing. 1.The operating environment of the slewing bearing In the selection stage of the slewing bearing, the operation environment should be described in detail. The following are several common use environments:  Humid environment:  water vapor should be prevented from entering the raceway and corroding the bearing surface, choose long lip seals or multi-lip seals, or even add multiple sets of seals. The large contact area between the seal and the bearing can effectively...
