Abstract
The utility model relates to a mill sliding shoe bearing bush aligning device, which comprises sliding shoe bearing bushes, connecting studs, a convex sphere, a concave sphere, a hydraulic cylinder, an oil inlet, an oil outlet and an annular groove oil chamber. Holes corresponding to the oil inlet are arranged on the side of and at the central part of the convex sphere. The oil outlet is arranged below the rear end of the oil inlet. The annular groove oil chamber is arranged at the central part of the bottom of the convex sphere and corresponds to the hole below the oil outlet. The oil outlet is arranged at the central part of the annular groove oil chamber. The utility model has the advantages that the traditional structure of the convex sphere and the concave sphere is improved, the high-pressure oil lubricating pipeline is added to provide high-pressure forced lubrication to the contact surface of the convex sphere and the concave sphere, the lubrication between the convex spherical surface and the concave spherical surface is improved, the friction coefficient is reduced, the flexibility of the rotating aligning function of the convex sphere and the concave sphere is improved, and the automatic control system is used to intermittently supply high-pressure lubricating oil to the contact surface of the convex sphere and the concave sphere.
Description
Technical field
The utility model relates to a kind of grinding machine crawler shoe bearing shell, especially a kind of grinding machine slide shoe bearing bearing shell aligning device.
Background technique
At present, grinding machine is in the industrial departments such as mine, building materials, chemical industry, metallurgy, and the most general, the most general milling equipment occupies status of the utmost importance in mineral pulverizing and ultra-fine grinding processing.Along with developing rapidly of domestic and international grinding machine, more energy-conservation, efficient, the easy large-sized grinder of operation and maintenance becomes development trend from now on, and slide shoe bearing is the most critical parts of large-sized grinder.Slide shoe bearing is generally all formed with top bearing shell by 2, and every bearing shell all adopts protruding, recessed spheroid to support.Because inevitably can produce deflection deformation in the grinding mill barrel operation process, and the installation of each bearing shell of slide shoe bearing and foozle, the oil film thickness of each bearing shell will be inhomogeneous, the problem of unbalance loading occurs.In order to guarantee the lubricated state of equilibrium of fully liquid between bearing shell and axle journal, each bearing shell that supports grinding mill barrel all must be adjusted when factor affecting such as the deflection deformation of grinding mill barrel and installation foozle automatically.Along with domestic and international grinding machine maximizes, the load of its spring bearing is increasing, the influence of factors such as deflection deformation, installation and foozle that is subjected to grinding machine is also just big more, the resiliently deformable of the stressed generation of protruding, recessed ball surface of contact is also just big more, add the restriction of the manufactured materials of protruding, concave spherical surface, this resiliently deformable is big more, and frictional force is also just big more, and the performance of spherical aligning is also just poor more.This can not meet the demands fully by protruding, concave spherical surface self-aligning mode.
The model utility content
The utility model provides a kind of grinding machine slide shoe bearing bearing shell aligning device for solving an above-mentioned difficult problem of the prior art; The utility model comprises: the bearing shell 1 of slide shoe bearing, connection double-screw bolt 2, protruding spheroid 3, recessed spheroid 4, oil hydraulic cylinder 5, filler opening 6, oil outlet 7, annular groove oil pocket 8; Its concrete technological scheme is: middle part, protruding spheroid 3 sides is provided with and filler opening 6, the below, rear end of filler opening 6 sets out hydraulic fluid port 7, it is corresponding with the hole of oil outlet 7 belows that middle part, protruding spheroid 3 bottom surfaces is provided with annular groove oil pocket 8, and oil outlet 7 is arranged on the middle part of annular groove oil pocket 8; Recessed spheroid 4 is arranged on the inboard of oil hydraulic cylinder 5, the below of protruding spheroid 3 be arranged on recessed spheroid 4 above, the middle part, lower end of the bearing shell 1 of slide shoe bearing is fixed together by double-screw bolt 2 with the upper center of protruding spheroid 3, when the bearing shell unbalance stress, but protruding spheroid 3 and recessed spheroid 4 contact the sphere self-aligning, by automatic control high pressure pump system intermittence from filler opening 6 to oil outlet 7, the annular groove oil pocket of offering for protruding spheroid 3 bottoms 8 provides the extreme pressure lubricant more than the 10Mpa, reduce to contact the frictional force of sphere, increase the lubricants capacity that enters each lubricated operation point, promptly constitute a kind of grinding machine slide shoe bearing bearing shell self-aligning structure.
The beneficial effects of the utility model: be that traditional protruding, concave spherical surface contact structures are improved, increased the high pressure oil lubricating pipe protruding, recessed spheroid surface of contact has been carried out the high pressure pressure lubrication, improved the lubrication state between protruding, the concave spherical surface, reduce friction factor, improved the flexibility that protruding, recessed spheroid rotates the aligning function.Adopting automatic control system intermittent is that protruding, recessed spheroid surface of contact is for extreme pressure lubricant.
