Abstract
The utility model discloses a split self-aligning sliding bearing. The split self-aligning sliding bearing comprises a split steel sleeve and a split copper bush, wherein the steel sleeve is formed by two steel tiles with inner spherical surfaces; the matched end surfaces of the two steel tiles are V-shaped; the hole wall of the steel sleeve is spherical; the outer cylindrical surface of the steel sleeve is provided with a ring-shaped oil groove in the radial direction; the two sides of the ring-shaped oil groove are respectively provided with a radial groove; through holes are uniformly distributed on the periphery of the end surface of the steel sleeve; the ring-shaped oil groove is provided with a steel-sleeve oil duct running through the through holes and the inner spherical surfaces; the copper bush is formed by two copper lining tiles; the matched end surfaces of the two copper lining tiles are V-shaped; the outer wall of the copper bush is an outer spherical surface matched with the inner spherical surface of the steel sleeve; the hole wall of the copper bush is provided with a spiral oil groove; and the copper bush is provided with a bush oil duct which penetrates through the hole wall and is communicated with the steel-sleeve oil duct. The split self-aligning sliding bearing disclosed by the utility model can improve the disassembling and replacing speed and can resist impact and vibration; and after a rolling bearing is damaged in site, the split bearing can be directly arranged in a bearing seat hole without disassembling a shaft end coupler, so that the installation is fast and convenient, and the service life of the bearing can reach an expected value and can be monitored.
Description
Technical field
The utility model belongs to the improvement of sliding bearing structure, particularly a kind of split type aligning slide bearing.
Background technique
Aligning antifriction bearing is adopted in the former design of bearing of changeing the steel rider road before and after steel rolling mill's heavy and medium plate mill usually; Field replacement is very difficult after the damage of bearings; With the complete replacing of roller-way or existing monodromy bearing all need ten at every turn surplus hour, and because the ways that adopt oxyacetylene metal-cutting to destroy and remove, inner hole of bearing seat is injured easily more; Can not guarantee running precision after new bearing is installed, working life is lower.
Summary of the invention
The purpose of the utility model is to provide a kind of split type aligning slide bearing, and it is rational in infrastructure, can improve the speed of changeing; Shock-resistant vibrations; On-the-spot damage back destruction taking-up when rolling bearing, need not to dismantle the axle head shaft joint, can be directly split bearing be packed in the bearing saddle bore; Quick for installation, can reach expection working life and also can monitor.
The purpose of the utility model is achieved in that a kind of split type aligning slide bearing; Constitute by split type inner ball surface steel bushing and split type outer spherical surface copper bush; Split type inner ball surface steel bushing watt is made up of two inner ball surface steel, and the counterface of two steel watt is a V font counterface, and the hole wall of split type inner ball surface steel bushing is a sphere shape; The center of steel bushing external cylindrical surface radially is being provided with annular oil groove; The radial groove of symmetry is being set respectively on the steel bushing external cylindrical surface of annular oil groove both sides, on the end face circumference of steel bushing, is being uniformly distributed with through hole is being set, the steel bushing oil duct that connects through hole and inner ball surface is being set on annular oil groove; Split type outer spherical surface copper bush is made up of two outer spherical surface copper lining tiles; The counterface of two copper lining tiles is a V font counterface; The outer wall of copper bush is shaped as the outer spherical surface that matches with the inner ball surface of steel bushing; The oil groove of wire in the shape of a spiral is being set on the hole wall of copper bush, on the outer spherical surface of copper bush, is being uniformly distributed with the lining oil duct that penetrates hole wall is being set, the lining oil duct is communicated with the steel bushing oil duct.
The utility model is made up of split type inner ball surface steel bushing and split type outer spherical surface copper bush; The point groove was involutory when on-the-spot subdivision was installed to axle journal; Twice groove place, outer ring adopts iron wire to tie up; The middle part slotted eye is used for grease up, and endoporus has the screw lubrication oil groove, and 6 through holes of end face are used for dismounting and storage lubricating grease.
The outer spherical surface neck bush, material is selected CuAl10Fe5Zn5 for use, and intensity is high, shock-resistant, wear-resisting; The maximum diameter place is the tube reducing cylndrical surface, trapped fuel and material saving, the concavo-convex involutory location of 90 degree, subdivision place; Endoporus has helical oil groove and communicates with 6 places, outer ring, guarantees lubricated good.
Through on-the-spot test on probation, the bearing that changes the steel rider road before and after the heavy and medium plate mill adopts the split type aligning slide bearing, and field replacement is convenient after the damage of bearings; The monodromy bearing only needs 3 hours at every turn; Can predict according to detecting bearing support Tong Gai hole and between centers crack side-play amount measuring and calculating copper bush wear extent working life, usually greater than two months, shock resistance; Operate steadily, satisfied usage requirement.
The utility model is rational in infrastructure, has improved the speed of changeing, shock-resistant vibrations; On-the-spot damage back destruction taking-up when rolling bearing, need not to dismantle the axle head shaft joint, can be directly split bearing be packed in the bearing saddle bore; Quick for installation, can reach expection working life and also can monitor.
