Hydraulic pullers are suitable for dismantling large, tightly fitting components. Due to the possibility of exerting a lot of pressure, they are useful where working with a mechanical puller will be very difficult or impossible. A wide range of devices allows you to find equipment suitable for a specific application, for example, for disassembling internal bearings, removing gears or hubs.How does the hydraulic puller work?
In various mechanical devices there are many elements that are attached to shafts or necks. In this way, gears, pulleys, hubs, pins, bushings or all types of bearings are most often installed. Connections of this type are very strong and practical, but their disconnection requires the use of appropriate tools and action with sufficient effort.For small parts, a simple mechanical puller is often enough. However, where the diameter of the shaft or neck and the size of the wheel or bearing are larger, it is necessary to apply greater efforts, and often also to heat the element or use lubricants. Such methods are troublesome and time-consuming, requiring, for example, very strict temperature control so as not to change the structure of the material. A much better solution is to use a device that guarantees the uniform transmission of a large force, for example, a hydraulic puller.The principle of operation of the hydraulic puller is the same as that of the mechanical puller. The movable puller levers include the rear part of the disassembled element in the case of, for example, a gear or the inner ring of a bearing. The mandrel of the puller rests against the geometric center of the shaft on which the element is mounted. The difference in the operation of both devices is that in a mechanical puller, the corresponding force is obtained by rotating the threaded mandrel, and in a hydraulic one due to the protrusion of the piston on which the mandrel is fixed.Types of Hydraulic Pullers
Hydraulic pullers, like all devices using stored energy in the liquid, are capable of providing very high force, which facilitates the dismantling of tightly fitting elements. Hydraulic pullers are relatively simple systems equipped with a drive and a pump filled with a suitable hydraulic medium.Various design solutions are available for this type of device. The appropriate medium pressure can be achieved using the supplied hand pump. It supplies the refrigerant at the correct pressure through a tube that goes to the cylinder installed in the puller. Another possibility is a one–piece design in which the hand pump is built directly into the puller and is located above the cylinder. The largest pullers are also available with an external pump powered by electricity.Each of the structures has its own additional advantages. The built-in puller is more compact. The plug-in pump, on the other hand, can also be used in other cases where manual supply of hydraulic fluid is required.Hydraulic pullers, as well as mechanical versions, are manufactured with various possible openings and departures, and can also reach various pressures from several to more than a hundred tons. There are also solutions adapted to the type of components being processed. In addition to the shoulder pullers, you can find models with a fork system or internal bearing pullers.
