Abstract
The utility model provides an inner aligning type bearing of a ball grinding mill with a cylindrical roller, which solves the fitting difficulty of the inner spherical surface of a bearing pedestal. A special scheme to be adopted is as follows: an inner spherical surface cushion is additionally arranged outside an outer spherical surface cylinder bearing; the outer surface of the inner spherical surface cushion is cylindrical, and the inner surface of the inner spherical surface cushion takes the shape of an inner spherical surface; the inner spherical surface cushion is arranged on the outer lower semi-spherical surface of the outer spherical surface cylinder bearing; and the inner spherical surface cushion is arranged in the low half inner cylindrical surface of an inner cylindrical surface bearing pedestal. The inner aligning type bearing has the beneficial effects: the outer spherical surface of the bearing and the inner spherical surface of the ball cushion which is matched with the outer spherical surface of the bearing are ground and machined, the dimension accuracy and the aligning performance of the bearing completely reach expected effect; the machining difficulty of the bearing pedestal is solved; and the manufacturing cost is reduced.
Description
Technical field
Self-aligning pebble mill bearing belongs to rolling bearing in the cylindrical roller, especially belongs to the special-purpose rolling bearing of pebble mill.
Background technique
Pebble mill is one of main production equipments of industries such as metallurgy, mining, cement, and wherein the pebble mill bearing is one of pebble mill vitals.What the pebble mill bearing was with the most use is sliding bearing, i.e. bearing shell.The sliding bearing main feature be the rotation the axle and bearing shell between be sliding friction, friction factor is big, power consumption is big.Rolling bearing also is applied on the pebble mill, and the main characteristics of rolling bearing are that kinematic pair is rolling friction, and coefficient of rolling friction is obviously less than the coefficient of sliding friction, and energy-saving effect is remarkable; Therefore advancing the pebble mill bearing elementization has been inevitable.Pebble mill has multiple with rolling bearing, spheric roller bearing is arranged, and the outer spherical surface roller bearing is arranged, and the outer spherical surface of adding pad (7) roller bearing (seeing Fig. 1, Fig. 2) is arranged, and combination property considers that the outer spherical surface roller bearing is better than spheric roller bearing; And ectosphere cushion roller bearing is better than the outer spherical surface roller bearing, so the large-size ball mill bearing is mainly selected the outer spherical surface roller bearing, or ectosphere cushion roller bearing.But the outer spherical surface roller bearing is outer aligning, no matter bearing with spherical outside surface or ectosphere cushion bearing, mining equiment manufactory all wants inner ball surface bearing support of turning processing, in order to reach aligning effect freely, the necessary bedding-in of bearing support inner ball surface and bearing outer spherical surface, not only workload is very big, and difficulty is very big, in addition also need processing inner ball surface equipment, influenced the popularization process of pebble mill bearing elementization.
Summary of the invention
The utility model provides self-aligning pebble mill bearing in a kind of cylindrical roller, has solved the difficulty of inner ball surface bedding-in.
The concrete solution that the utility model is taked is: outer spherical surface cylindrical bearing 6 is made up of outer ring 1, roller 2, inner ring 3 and retainer 5, and outer spherical surface cylindrical bearing 6 outsides install self-aligning pebble mill bearing in the inner ball surface pad 8 formation cylindrical rollers additional.
Described inner ball surface pad 8 outsides are cylindric, and inner face is that endosphere is planar.
Described inner ball surface pad 8 is installed at the outer lower semisphere face portion of outer spherical surface cylindrical bearing 6.
Described inner ball surface pad 8 is assemblied in second inner cylindrical surface of inner cylindrical surface bearing support simultaneously.
Self-aligning pebble mill bearing has positioning bearing and two kinds on the bearing of moving about in the described cylindrical roller.
Helpful being of the present utility model: the bearing outer spherical surface with and its ball pad inner ball surface of matching all be grinding, its dimensional accuracy and aligning performance have reached Expected Results fully; Solve the bearing support difficulty of processing, reduced manufacture cost.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the existing ectosphere pad roller bearing positioning bearing schematic representation that adds;
Fig. 2 is the existing ectosphere pad roller bearing bearing schematic representation that moves about that adds;
Fig. 3 is a self-aligning pebble mill bearing positioning bearing schematic representation in the cylindrical roller;
Fig. 4 is the self-aligning pebble mill bearing bearing schematic representation that moves about in the cylindrical roller.
Among the figure: outer ring 1, roller 2, inner ring 3, back-up ring 4, retainer 5, outer spherical surface cylindrical bearing 6, outer spherical surface pad 7, inner ball surface pad 8.
Embodiment
Shown in Fig. 3,4, install inner ball surface pad 8 in outer spherical surface cylindrical bearing 6 outsides additional and form self-aligning pebble mill bearing in the cylindrical roller; Inner ball surface pad 8 outsides are cylindric, and inner face is that endosphere is planar; Inner ball surface pad 8 is installed at the outer lower semisphere face portion of outer spherical surface cylindrical bearing 6; Inner ball surface pad 8 is assemblied in second inner cylindrical surface of inner cylindrical surface bearing support simultaneously.What self-aligning pebble mill bearing was equipped with back-up ring 4 in the cylindrical roller is the positioning bearing (see figure 3), and what do not adorn back-up ring 4 is the bearing (see figure 4) of moving about, and each needs a cover table grinder.Owing to the outer spherical surface of outer spherical surface cylindrical bearing 6 with and the inner ball surface of its inner ball surface pad 8 of matching all be shaped through grinding, its machining accuracy height, mated condition are good, aligning performance is good, has reached Expected Results fully; Need not reprocess and grind inner face to bearing support, simplify the manufacturing process of bearing support greatly.
Described above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; every bearing with spherical outside surface adds the bearing of an inner ball surface pad combination; no matter how other structure changes, how material is selected, and all belongs to the row of the utility model patent protection.
