VE10 Vertical Worm Gear Slew Drive With Self-Locking For Heavy Duty Applications

VE10 Vertical Worm Gear Slew Drive With Self-Locking For Heavy Duty Applications

Vertical Worm Gear Slew Drive​ Description

The VE10 Vertical Worm Gear Slew Drive is a compact, high-strength rotary drive designed for applications that require reliable load rotation, high overturning moment capacity, and stable positioning. With an integrated slewing ring and enveloping worm gear mechanism, the VE9 combines the functions of a slewing bearing and gearbox into one compact drive unit.

Its reverse self-locking worm gear design helps prevent the driven load from back-driving the mechanism when power is removed, making it particularly suitable for lifting equipment, aerial work platforms, high-altitude machinery, material handling systems, positioning equipment, and other applications where load stability is critical.

The VE9 provides a rated output torque of 16,000 N·m, a tilting torque capacity of 12,000 N·m, and a holding torque of 70,000 N·m, providing a strong balance between compact dimensions, load capacity, and positioning performance.

Features

1. Integrated Slewing Drive Design

The VE10 integrates the slewing ring, worm gear transmission, housing, and supporting components into a complete rotary drive assembly. This integrated structure eliminates the need to separately select, machine, and assemble multiple transmission components. For equipment manufacturers, this can simplify mechanical design, shorten assembly procedures, and reduce the number of components required in the rotary mechanism.

2. Reverse Self-Locking for Load Stability

One of the key advantages of the VE10 is its worm gear self-locking capability.

Under suitable load and operating conditions, the worm gear mechanism can resist reverse rotation from the output side. This characteristic is valuable for equipment where the load needs to remain in position when the drive motor is stopped or power is removed. The self-locking design makes the VE10 particularly suitable for:

• Lifting and positioning equipment

• Aerial work platforms

• High-altitude operating machinery

• Material handling equipment

• Rotary positioning systems

• Construction machinery

• Solar tracking and other outdoor positioning applications

The actual self-locking performance should be evaluated according to the load, installation orientation, lubrication, operating conditions, and safety requirements of the complete machine.

3. High Overturning Moment Capacity

The VE10 uses a slewing ring as the primary load-supporting component, allowing it to handle not only rotational torque but also significant external overturning loads.

The 12,000 N·m tilting torque rating provides additional capacity for applications where the center of gravity is offset from the rotational axis. This makes the VE10 suitable for mechanisms in which the rotary drive must support both the rotating structure and external loads.

4. Enveloping Worm Gear Transmission

The VE10 adopts an enveloping worm drive, providing increased tooth contact between the worm and worm gear compared with conventional worm transmission designs.

The multi-tooth engagement helps distribute the transmitted load across a larger contact area, contributing to:

• Higher load-carrying capability

• Smooth rotary motion

• Stable torque transmission

• Improved resistance to shock loading

• Compact transmission design

This transmission structure is especially beneficial for heavy-duty rotary applications where space is limited but load capacity remains important.

5. Compact Solution for Simplified Machine Design

Traditional rotary mechanisms may require a separate slewing bearing, gearbox, pinion, shaft, and mounting structure. The VE10 combines the main rotary transmission functions into one integrated unit.

This can help equipment manufacturers:

• Reduce the number of mechanical components

• Simplify mounting and assembly

• Reduce the required installation space

• Simplify the host machine structure

• Reduce potential mechanical failure points

• Improve overall system integration

VE10 Slew Drive Selection

Selecting a slew drive should not be based only on rated output torque. The complete operating conditions should be considered, including:

• Total moving load

• Center of gravity and eccentric load

• Tilting moment

• Axial and radial loads

• Required output speed

• Rotation angle

• Operating cycle and duty time

• Installation orientation

• Environmental conditions

• Required self-locking or braking performance

For a customized VE10 vertical worm gear slew drive, Hangtuo can evaluate the drive according to the actual load and mechanical configuration of your equipment.
