Description
Technical field
The utility model relates to a kind of oil-sealing arrangement of experimental facilities, is specifically related to a kind of oil-sealing arrangement for high-speed balancing testing equipment.
Background technology
At present, the oil-sealing arrangement of high-speed balancing testing equipment is made up of oil sealing end cap and oil scraper ring.During use, first need oil sealing end cap to be arranged on testing equipment, and then be fixed by bolts to by oil scraper ring on oil sealing end cap, the oil-sealing arrangement that testing equipment uses is cast iron quality.Because the size of different rotor is different, thus cause installation site, the size difference of oil-sealing arrangement, and then make oil-sealing arrangement and oil scraper ring thereof need often to dismantle and be replaced by the oil-sealing arrangement of different size, therefore exist and change loaded down with trivial details problem.Meanwhile, because the weight of cast iron is comparatively large, and the axial dimension of part rotor is comparatively large, and the oil-sealing arrangement that testing equipment provides can not meet concrete request for utilization, thus has that work efficiency is lower, dimensional flexibility is poor, the problem of oil sealing weak effect.
Utility model content
The utility model is intended to provide a kind of oil-sealing arrangement for high-speed balancing testing equipment, and to solve the deficiencies in the prior art, the technical problems to be solved in the utility model is achieved through the following technical solutions.
For an oil-sealing arrangement for high-speed balancing testing equipment, comprise oil sealing end cap and oil scraper ring; Described oil sealing end cap adopts aluminum alloy materials integrated punching shaping, overall in semi-annular shape, it comprises oil sealing bearing shell and oil sealing installing plate, the external diameter that the internal diameter of described oil sealing installing plate is equal with the internal diameter of oil sealing bearing shell and aperture surface is coaxial, external diameter is greater than oil sealing bearing shell, the described oil sealing bearing shell in the axial direction end face of one end and oil sealing installing plate, the other end stretches out and is longer than oil sealing installing plate and the length of extending is the length that can adapt to multiple rotor type; Described oil sealing installing plate circumferentially array has multiple threaded hole for being fixedly connected with the rocker bolt of experimental facilities, and described oil sealing bearing shell aperture surface is provided with multiple back-shaped fitting recess; Described oil scraper ring adopts epoxy resin board make and be embedded in fitting recess; By bolt, oil sealing end cap is fixedly connected with rocker, and oil scraper ring is embedded in the fitting recess on oil sealing bearing shell aperture surface, then experiment rotor be plugged in oil sealing bearing shell thus realize the sealing to experiment rotor.
The utility model adopts the oil sealing end cap of aluminum alloy material, the oil scraper ring of epoxy resin board material, oil sealing bearing shell aperture surface arranges back-shaped fitting recess, and the fit system of oil sealing end cap and oil scraper ring fixedly changes oil scraper ring into by traditional bolt can be embedded in form in fitting recess.The axial dimension of oil sealing bearing shell lengthens, and can adapt to the oil sealing position dimension of multiple rotor.Dismounting and the installation of oil-sealing arrangement can be facilitated after changing material; Increase the axial dimension of oil sealing bearing shell, the kind of adaptive rotor can be increased, strengthen the installation of oil-sealing arrangement, use dirigibility; Change the fit system of oil sealing bearing shell and oil scraper ring, dismounting and the installation of oil scraper ring can be facilitated, and oil sealing effect can be strengthened.
The beneficial effect that the utility model has: structure is simple, installation and removal are convenient, can the installation site of flexible adaptation oil-sealing arrangement and dimensional requirement and oil sealing is respond well.
