9 Inches Reverse Self Locking Worm Gear Slewing Ring For Adjustable Mount Bracket
Self Locking Worm Gear Slewing Ring Description
A distinctive feature of the rotary worm gear drive is the feature between static self-locking and dynamic self-locking. When the startup efficiency ηA ≤ 0.5, static self-locking exists. At this time, it is impossible to drive the worm by rotating the slewing bearing. Sometimes, this self-lock can be invalidated by some external force such as external vibration. At this time, the worm can be driven by the rotary slewing bearing. When the operating mechanical efficiency η ≤ 0.5, the helix angle γm=2.5°~4°, which can achieve dynamic self-locking (that is, automatic locking during movement), which can be achieved by relying on the contact stress and friction of the tooth surface.
In many drive systems, self-locking is very important. In general, using additional brakes or blocks is the most common method. Self-locking gears cannot completely replace the role of brakes. The rotary worm gear drive is static self-locking. In some special cases, such as earthquakes, the self-locking is still effective when there is a tendency to reverse rotation. Our slewing drive has features of reverse self-locking because of worm gear self-locking characteristics. This feature greatly enhances the stability of the host operating and safety factor. Compared to the traditional swing products, slewing drive gearbox is easy to install, easy to maintain, and saves considerable installation space.
