China Good quality EGE17 Series Slewing Drive with high quality

Slew drive is an advanced version of the conventional worm and worm wheel technology. This assembly incorporates a worm shaft and a slew ring bearing, making it almost frictionless. Such Slew drives are perfect for applications that require both load holding and rotational torque from the same gearbox. The drives come with an hourglass worm technology, which increases the drives’ efficiency. The difference between standard and hourglass technology is that, in a conventional worm gearing system, only 1 tooth of the gear is in contact with the worm shaft, whereas in our systems, it can go up to 6 gears in touch.

The slew drive comes in 2 types: single row ball and double row ball. These are selected depending on the load coming on the drive. The drive is designed to carry huge loads despite the compact form factor. Higher loads generally need double row slew bearing. The drives come with an IP65-rated protection system, which protects the drive from environmental conditions and dirt, sand, dust, and even water. The gears used in the assembly are hardened and ground to provide maximum durability and longer life.

Due to their compact design, slew drives are well suited for usage in the construction, agriculture, and forestry industries. Examples are loading cranes, aerial working platforms, and steering systems for special vehicles.

What Matters Should Be Paid Attention to When Using Slew Drive?

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 delivered to the user. It needs to be connected and assembled with the host when it is returned 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 relationship 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. The other holes reserved by the manufacturer of the slew drive for the user are installed with the host. Therefore, we must keep these pre-connections in the same flange holes when connecting with the host. In this process, the original assembly form of the slewing drive must not be destroyed so as not to damage its transmission efficiency.

The slewing drive delivered to the user has been filled with lubricating oil before leaving the factory. When the main machine is given to the user, the user must be informed to regularly fill in lubricating oil and maintain it following the rules for the use of the slewing drive.

Although the slewing drive product has the characteristics of high integration, simple structure, and superior performance, reasonable use is still significant, and daily maintenance is also indispensable. In construction machinery, most slew drive products are unsuitable for high-speed and high-frequency running back and forth under the condition of significant impact, pay attention to reducing the effect of the start and stop stage during the operation. In particular, don’t subtract the throttle savagely without transition, which is an excellent benefit to prolonging the service life of the machine and parts. In other low-speed, heavy-load, and long-period working environments, regular replacement and refilling of grease according to design requirements, timely removal of jams and blockages caused by foreign objects, the slew drive can maintain long-term stable and efficient operation.

Unique Transmission slew drive products have reliable technology and first-class quality. Due to having the crucial processing equipment and perfect quality control methods, the product reliability is high. At the same time, due to its robust design capabilities, it can respond to various special needs of users. Unshaped products can be customized for customers and cooperate with customers to provide technical consultation and related information support in the design stage of host products.
