Hydraulic nuts lock massive workpieces and secure bolts that must be frequently disassembled, reassembled, pre-tightened, and tightened. They can also be used as hydraulic historyglow interferences to connect tools for disassembly. Moving or installing bearings from tapered shafts or sleeves is often complicated and time-consuming. Utilizing hydraulic nuts could increase work efficiency and ease of work. Issues.
The principle of the hydraulic nut tightener is that the hydraulic oil is input into the nut by the high-pressure oil pump to generate the force that pushes the piston, which meets the needs of installing or disassembling the bearing effortlessly, accurately, and safely.
The basic principle behind this nut is to use ultra-high pressure oil to create an upward push on the shaft and tension in the shaft sleeve, to ensure that the shaft and shaft sleeve are connected through the force.
- In metallurgy, the copper and aluminum industries, paper manufacture, hydraulic locking on slitting machines, etc., hydraulic nuts are widely utilized.
- Install and remove propeller shoes for rudders, etc.
- Take off the high-pressure surface, including train wheels, couplings, flywheels, and gears.
Hydraulic nuts are an advanced bolt assembly technique, ideal for tight space and vibrations from heavy loads mechanical techybio fastening.
The principle behind the hydraulic nut is that it uses the hydraulic cylinder to apply force externally to the bolt, ensuring that the bolt being applied is stretched within the elastic range of deformation. The lock ring on the hydraulic nut is tightened once the bolt has been extended to make sure it is securely fastened. The ring is then locked into the extended position.
The hydraulic cylinder is situated on the central axis of the bolt, and it is employed to stretch the bolt to attain the amount of stretching required for the bolt.
The amount of tension on the bolt determines the force needed to tighten the bolt. When the nut of the hydraulic is pressured, the bolt is stretched, and at the same time, the hydraulic nuts are near the joint’s surface. This means there is a lateral deformation in the bolt that becomes secured, meaning that the rest of the bolt load is secured in the nut.
- The stretching method isn’t affected by the bolt lubrication effects and thread friction, and therefore, a more precise load is possible to obtain.
- The bolts may be stretched simultaneously to ensure that the whole circle of bolts is equally tensioned and a balanced load is achieved.
- The most modern ultra-high pressure hydraulics can lock bolts into the smallest space.
- The practical and residual load obtained from tightening the bolts using the tensile method is higher than the ones obtained using the torque method.
- The stretching technique is more appropriate for joint applications that require a high degree of tightening precision. It will stretch the joint face equally to create joints and prevent leakage.
- Ideal for all kinds of rotation, including fast-speed high-power equipment, and small spaces.
- Efficient and cost-effective, lightweight, High precision, lightweight.
- It can be fitted with manual hydraulic pumps or pneumatic hydraulic pumps as well as electric hydraulic pumps.
- Multiple hydraulic nuts may be employed simultaneously.
- There is no requirement to use a gauge; however, the measuring ring included in the design of the structural overallnetworth structure could be used to precisely and precisely evaluate an axial distance needed by the bearing.
- In assembling and removing the sleeve for withdrawal, it is possible to use hydraulic nuts that meet the exact specifications. However, this is not available in patent-protected hydraulic nuts fitted with gauges and hanging connect blocks.
