Slew DriveThree Major Advantages
Aug 22, 2017

Rotary drive is a full-cycle rotary slowdown drive with integrated drive power source. It is used as a drive follower and mechanism attachment. By attaching a drive on a ring in the inner and outer rings of the slewing ring, the drive source And the other housing is used as both a drive follower and as a connecting base of the driven working part, so that the use of the rotary support itself is the characteristics of the whole cycle of the rotary joint, and the power source and the main drive Parts, making it a set of rotary, deceleration and drive functions in one while the structure is simple, easy to manufacture and maintain the general-purpose slowdown transmission.

According to the rotary drive variable transmission form distinction, can be divided into tooth-type rotary drive and worm gear-type rotary drive, inherited gear drive and worm gear drive their own characteristics, the two rotary drive can be adapted to high-speed and low-speed applications, In terms of carrying capacity, the performance of the worm gear is better than that of the gear, and when the envelope worm is used, its carrying capacity, resistance to deformation and transmission rigidity are further improved, but the efficiency of the worm gear Inferior to tooth rotation drive.

According to the open drive drive sub-mechanism of the open distinction, the rotary drive can be divided into open and closed, usually open structure for the environment is too harsh, maintenance and maintenance cycle of short applications, open structure easier to machine The inspection, maintenance and maintenance, but also more convenient to replace. The closed structure can provide a longer maintenance life cycle when the environmental conditions change little or less, and below the following environmental pollution levels.

Rotary drive the three major advantages:


Due to the high degree of integration of the rotary drive, the user does not have to purchase and process each of the accessories that make up the rotating device, and to a certain extent reduce the preparation process at the beginning of the product production, thereby greatly improving the labor productivity.

2. security

Worm gear drive with reverse self-locking characteristics, can achieve reverse self-locking, that is, only by the worm to drive the worm, and can not be driven by the worm gear worm. This feature allows the rotary drive can be widely used in lifting, aerial work and other equipment, while improving the host's scientific and technological content, but also greatly enhance the stability of the host operating and operating safety factor. Rotary drive with the traditional rotary products compared to the installation is simple, easy to maintain, to a greater extent, save space for installation.

3. Simplify the host design

Compared with the traditional gear drive, the worm gear drive can get a relatively large reduction ratio, in some cases, the host can save the reducer parts, so as to reduce the cost of procurement customers, but also greatly reduces the host failure rate.
