Abstract
The utility model relates to a grinding machine bearing which comprises an inner sleeve and an outer sleeve. The utility model is characterized in that the outer diameter the outer sleeve of the bearing is in the shape of a spherical surface; double-row cylindrical rollers are arranged between the outer sleeve and the inner sleeve; one side of the inner sleeve is provided with a single stop edge, and the other side of the inner sleeve is provided with a flat stop ring; the width of the inner sleeve plus the width of the flat stop ring equals the width of the outer sleeve. The outer sleeve of the utility model adopts an outer spherical surface structure. When the bearing is installed and used, the shaft line of the bearing can be aligned from 15 DEG to-15 DEG, and accuracy errors generated in the installation and processing of a machine body can be compensated. In addition, the outer sleeve of the bearing is provided with a plurality of positioning holes; the positioning holes are corresponding to positioning pins on a spherical surface supporting seat, and each positioning hole and each positioning pin have the same diameter; the periodical angular transposition of the bearing in certain angle can be carried out via the positioning holes; the abrasion between the cylindrical rollers and a raceway can be reduced, and maximum rigidity and minimized friction coefficient in rotation can be obtained. Consequently, the service life of the bearing is enhanced. Because the utility model adopts grease lubrication, the utility model does not need water to cool, the service life is more than 15 years and the utility model obtains obvious effects on power saving and water saving.
Description
(1) technical field
The utility model relates to a kind of bearing, particularly relate to be exclusively used in tuber grinder, the rolling bearing on air swept mill the machine.
(2) background technique
The tuber grinder in past, wind are swept pebble mill and are adopted the sliding device of being made by " Babbitt " materials such as " phenolic plastic " always, and this sliding device exists many disadvantages such as power consumption is big, fault is many, befouling environment, maintenance difficult in actual use.In addition, because therefore this kind sliding device can not can not remedy the trueness error that body produces in the transposition adjustment of positive negative justification of axis and several angle when processing and install when installing and use, greatly reduce the working life of grinding machine.
(3) summary of the invention
The purpose of this utility model provides a kind of grinding machine bearing with energy efficiency, easy to maintenance, long service life.
The purpose of this utility model realizes by subordinate's technological scheme, that is:
The grinding machine bearing comprises interior cover, overcoat, and its structural feature is that described bearing outside external diameter is a sphere shape, has double-row cylindrical roller between overcoat and the interior cover, interior cover has a side band single block border, and the opposite side of interior cover adds loose rib, and it is identical with the overcoat width that interior cover width adds the loose rib width.
The middle part of above-mentioned bearing outside external diameter has a plurality of through holes of arranging in the form of a ring.
Overcoat of the present utility model has adopted the outer spherical surface structure, can make the aligning of positive and negative 15 degree of axis in the installation of bearing with when using, and has remedied the trueness error that body produces in processing with when installing.The a plurality of through holes that put outward can be corresponding with the locating stud of the spherical bearing watt seat of same diameter, reduce the friction of cylindrical roller and raceway and obtain to rotate in maximum rigidity and minimum friction factor, thereby the working life of raising bearing.
The utility model has adopted grease lubrication, need not to use water cooling, and have significant energy-saving and water-saving effect more than 15 years working life.
(4) description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
(5) embodiment
Grinding machine bearing of the present utility model, cover 1, overcoat 2, loose rib 3 and the retainer that a plurality of cylindrical rollers 8 are housed in comprising.The external diameter of overcoat 2 is a sphere shape.Symmetrical ring is provided with two rail grooves 4 on the inner wall surface thereof; Loose rib 3 leans on the annular end face of interior cover 1 one ends, the outer rim retaining of loose rib 3 the other ends is in roller 8 outsides, the structure of two retainers is identical, by keeping stand 5, retainer lid 6 and pillar 7 constitute, and cylindrical roller 8 is a hollow roller, and pillar 7 penetrates roller 8 and is fixed on maintenance stand 5 and the retainer lid 6, there are 4 through holes 9 overcoat external diameter center, and wherein 3 through hole doors can be positioned on the spherical bearing block of same diameter by the overcoat of locating stud with bearing.Another through hole can be used as oilhole 9.
Claims (2)
1, grinding machine bearing, comprise interior cover (1), overcoat (2), it is characterized in that described overcoat external diameter is a sphere shape, has double-row cylindrical roller between overcoat (2) and the interior cover (1), interior cover (1) has a side single block border, the opposite side of interior cover (1) adds loose rib, and the width that interior cover (1) width adds loose rib (3) is identical with the width of overcoat (2).
