Brief: Bevel gear ball screw jacks features: Higher speeds and less heat generation than other mechanical actuators. Require a brake or other external locking device to hold position. More precise positioning and repeatability than hydraulic cylinders. Right hand screws standard (left hand screw available). Threaded end conditions standard (top plate, clevis, threads and plain end condition available). Protective boots and other options are available. Custom finishes available.
Brief: The decision to use a bevel gear ball screw jack or a bevel gear machine screw jack is based on the application. For many applications, a ball screw model is the best choice. Bevel gear ball screw jacks are more efficient and therefore require less power than a bevel gear machine screw jack in the same application. For low duty cycle applications, for hand-operated applications, or if back driving is not acceptable consider a bevel gear machine screw jack. Bevel Gear Ball Screw Jacks are preferred for Long travel lengths, Long, predictable life, High duty cycles, and Oscillating motion. Bevel Gear Machine Screw Jacks are preferred for Vibration environments, Manual operation, and High static loads.
Brief: Another benefit of bevel gear jacks is their input and output shafts flexibility. They are available in single shaft, two shaft and three shaft configurations. In two and three 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.
Brief: Quick-lifting bevel gear screw jacks for extremely high-speed lifting operations. If fast-lifting jacks are in use, correct configuration can eliminate the need for mitre gear boxes. Axial lifting spindle; female thread integrated into bevel gear: Drive is provided by the driving pinion acting on the bevel gear with female thread. Lifting movement is provided by the spindle anti-turn device. The alignment of the bevel gear determines the direction of rotation. Rotating spindle; female thread in travelling nut outside the transmission housing: Drive is provided by the driving pinion acting on the bevel gear. Rotating movement is provided by the positive engagement of the spindle in the bevel gear. Lifting movement is provided by the traveling nut anti-turn device fitted onsite. Spiral mitre gear boxes permit high lifting speeds - high efficient rating and long service life.
Brief: High-speed bevel gear screw jacks supplement the existing screw jack range in the medium load range for high stroke speed and higher duty cycle. Gearboxes with ratios of 3:1 available. Hardened, polished and spiral-toothed bevel gearboxes. Mountable in any position thanks to the cubic design. Available with up to 4 output shafts.
Brief: Self-locking occurs when system efficiencies are low enough that the force on the lifting shaft cannot cause the drive system to reverse direction. All bevel gear screw jacks can back drive and require some means of holding the load, such as a brake on the motor. The product specification pages show holding torque values. Holding torque represents the amount of input torque required to restrain the load. In addition to back driving, system inertia usually results in some over travel when the motor is switched off. The inertia of the system should be considered when determining the brake size required to stop a dynamic load.
Brief: Bevel Gear Machine Screw Jacks are by the use of spiral bevel gears mechanism with self locking trapezoidal screws. These bevel gear jacks use bevel gears inside the housing instead of worm gearing. Bevel gears are more efficient than worm gearing—around 35% compared to 20%. So these bevel gear jacks offer higher efficiency and greater speed than other mechanical worm gear screw jacks, but a bit more expensive. As an added benefit, bevel gear jacks with three shafts also act as 90 degree bevel gearboxes, making them an ideal choice for multiple screw jack lift systems, which helps balance the difference in price.
