Product Description

Worm Gear Screw Jacks vs. Bevel Gear Screw Jacks. How To Select The Correct Types Screw Jacks For Your Application? When faced with the need to lift, lower, push or pull a load-especially a heavy load-and hold it in the correct position, a screw jack or multiple jacking system may provide the best linear motion solution when considering its performance and cost ratio. There are 2 main types of screw jacks: Worm Gear Screw Jacks, and Bevel Gear Screw Jacks. To determine the type of screw jack that is best for your application, you need to consider several factors, they are load, self-locking capabilities, travel rate or travel speed, efficiency, accuracy, duty cycle and price, among others.

Worm Gear Screw Jacks includes Machine Screw Jacks and Ball Screw Jacks. The key components of mechanical worm gear screw jacks are: trapezoidal lifting screw and lifting nut(machined screw jacks), or ball screw and ball nut(ball screw jacks), worm screw, worm gear and gear housing. The most common screw jack is the worm gear screw jack, also referred to as machined screw jacks because the acme, or trapezoidal, lead screw is machined. In addition to the low cost and self-locking characteristics, another advantage of machine screw jacks, and all screw jacks, is the mechanical advantage achieved through the internal gear ratio resulting in the ability to lift, lower, push or pull a significant load with a relatively small amount of torque on the drive shaft. Ball screw jacks incorporate a ball screw instead of a machined screw and a ball nut, which activates the screw. The advantage of ball screw jacks and the rolling action of their design is greater efficiency, up to 60%, which is much greater than machined screw jacks. Because of their efficiency ball screw jacks can be used in heavier duty cycle applications. They also provide good positional accuracy in high speed applications. One potential disadvantage is that ball screw jacks are not self-locking and will require a brake or motor with enough holding torque to prevent the ball screw from back-driving. 

Bevel Gear Screw Jacks Advance from having Screw Jack and Bevel Gearbox as a separate unit to a combined Miter bevel gearbox and Screw Jack in a single housing. The Bevel Jack product will save you money by offering less maintenance and fewer components. Available in many configurations, this line offers customers quality, long-duty cycles and configurable solutions for their applications. Available in Bevel Gear Machine Screw Jacks and Bevel Gear Ball Screw Jacks. Although worm gear jacks are sufficient for large loads that are infrequently moved, bevel gear jacks offer more flexibility and programmable options for a wider range of applications. The key components of bevel gear machine screw jacks use the same trapezoidal or CZPT screws used in machined screw jacks, or ball screws used in ball screw jacks to move the load. However, bevel gear jacks use spiral bevel gears set inside the housing instead of worm gearing. Bevel gears are more efficient than worm gearing, and they have lower ratios that result in higher speeds and travel rates. Typically, bevel gear machine screw jacks maintain self-locking characteristics while providing higher travel speeds, but bevel gear ball screw jacks incorporate a ball screw instead of a machined screw and a ball nut, which activates the screw. The advantage of bevel gear ball screw jacks and the rolling action of their design is greater efficiency, which is much greater than bevel gear machined screw jacks. Because of their efficiency bevel gear ball screw jacks can be used in heavier duty cycle applications. They also provide good positional accuracy in high speed applications. One potential disadvantage is that bevel gear ball screw jacks are not self-locking and will require a brake or motor with enough holding torque to prevent the ball screw from back-driving. 

Another benefit of bevel gear screw jacks is their drive shaft flexibility. They are available in single shaft, 2 shaft and 3 shaft configurations. In 2 and 3 shaft configurations the jack offers right angle characteristics with the ability to divide input power or torque, sending it equally in different directions. Flexibility in shaft configuration makes bevel gear jacks ideal for multiple jack configurations and can eliminate the need for stand-alone right angle gearboxes used in many worm gear jack systems.

Additionally, our bevel gear screws can be arranged in 3 jack configurations: translating, rotating and keyed. This allows the load to be moved in different ways along the lift shaft, offering further options for customers.

Can screw gears be used in automotive applications?

Yes, screw gears, also known as worm gears, can be used in various automotive applications. While other types of gears, such as spur gears and helical gears, are more commonly found in automotive systems, screw gears offer certain advantages that make them suitable for specific automotive applications. Here’s a detailed explanation of using screw gears in automotive applications:

  • Steering Systems: Screw gears are commonly used in automotive steering systems, particularly in rack and pinion steering systems. The worm gear and worm wheel arrangement provides a compact and efficient means of converting rotational motion into linear motion, allowing for precise and responsive steering control. Screw gears in steering systems can offer enhanced safety, reliability, and ease of operation.
  • Convertible Roof Mechanisms: Screw gears can be utilized in convertible roof mechanisms to facilitate the opening and closing of the roof.

How do screw gears contribute to linear motion and power transmission?

Screw gears, also known as worm gears, play a significant role in achieving linear motion and power transmission in various mechanical systems. Here’s a detailed explanation of how screw gears contribute to these functions:

Linear Motion:

Screw gears can convert rotary motion into linear motion or vice versa through the interaction between the worm and the worm wheel. The helical threads on the worm and the teeth on the worm wheel create a sliding and rolling contact that results in linear displacement along the axis of the screw. This mechanism enables precise control and positioning of linear motion in different applications.

The linear motion contribution of screw gears can be observed in the following scenarios:

  • Lead Screw Mechanisms: When the worm gear is used as a lead screw, it converts the rotary motion of the worm into linear motion along the screw’s axis. By rotating the worm, the worm wheel moves linearly, allowing for controlled and precise linear positioning. Lead screw mechanisms are widely used in applications such as CNC machines, 3D printers, and linear actuators.
  • Linear Motion Conversion: In certain applications, the linear motion of a load can be converted into rotary motion using screw gears. By fixing the worm wheel and applying linear force to the worm, the rotation of the worm can drive the rotary motion of other components. This conversion is utilized in applications such as conveyor systems, lifting mechanisms, and material handling equipment.

Power Transmission:

Screw gears are effective in power transmission due to their unique characteristics. Here’s how they contribute to power transmission:

  • Gear Reduction: Screw gears provide significant gear reduction, which is the ratio between the input speed and the output speed. This reduction allows for a smaller input speed to generate a larger output torque, making screw gears suitable for applications requiring high torque and low-speed rotation. The gear reduction capability of screw gears enables efficient power transmission, especially in scenarios where high torque is necessary.
  • Torque Multiplication: Through the interaction of the helical threads on the worm and the teeth on the worm wheel, screw gears multiply torque. The mechanical advantage gained through the screw gear mechanism enables the transmission of higher torque to drive loads with increased force. This torque multiplication is essential in applications that require heavy lifting, load handling, and power transmission with minimal slippage.

By combining the ability to convert rotary motion into linear motion and providing efficient power transmission, screw gears find widespread use in a range of applications. They are employed in industries such as manufacturing, automation, robotics, material handling, and various other systems that require precise linear motion control and effective power transmission.
