Abstract
The invention discloses a precisely-sealed bearing. The precisely-sealed bearing comprises an outer ring, rollers, a roller retainer, an inner ring and a sealing cover. The rollers are arranged between the outer ring and the inner ring through the roller retainer. A boss is arranged at the upper end of the sealing cover. A groove corresponding to the boss at the upper end of the sealing cover is formed in the inner side of the outer ring. An oil injection nozzle is arranged on the outer surface of the sealing cover. An oil discharging nozzle is arranged on the outer surface of the sealing cover, and the size of the oil discharging nozzle corresponds to the size of the oil injection nozzle. A dismounting and mounting groove point is arranged on the outer surface of the sealing cover. By adoption of the technical means, the precisely-sealed bearing has the beneficial effects that the precisely-sealed bearing is simple in structure and convenient to dismount, mount and maintain. Lubricating oil is injected under the condition that the sealing cover of the bearing does not need to be dismounted or mounted, daily maintenance of the bearing is facilitated, the service efficiency of the bearing is improved, and the service life of the bearing is prolonged.
Description
Technical field
The present invention relates to technical field of bearings, and in particular to a kind of precision sealing formula bearing.
Background technology
Bearing is a kind of important spare part in plant equipment, and with scientific and technological constantly development, the use field of bearing is also more next
It is more.The major function of bearing is supporting machinery rotary body, reduces the coefficient of friction in its motion process, and ensures its revolution essence
Degree.Its normal work is affected to prevent Bearing inner accumulated impurity, is also to ensure lasting for the lubricating oil in bearing, to extend
The life-span of bearing, therefore more bearing is all sealed bearing.Current sealed bearing is by outer ring, inner ring, roller, roller
Retainer, closure composition, by closure by the roller of bearing and roller cage closure the outer ring of bearing and inner ring it
Between, form sealed bearing.Although so solve preventing dust from entering bearing, lubricating oil usage cycles are improve.But,
Need to dismount its closure in bearing replacing bearing oil, lubricating oil is filled after being cleared up, waste time and energy, to normal
Working service brings very big inconvenience, also have impact on the service life of bearing.And often occur when closure is dismounted close
Capping wrecks, that is, cause the trouble of the dismounting maintenance of bearing, reduces the reliability of its working service.
The content of the invention
To solve above-mentioned technical problem, the invention discloses a kind of convenient filling lubricating oil, is easy to dismount the precision safeguarded
Sealed bearing.
A kind of precision sealing formula bearing, including outer ring, roller, roller cage, inner ring and closure, roller is protected by roller
Hold frame to arrange between outer ring and inner ring, closure upper end is provided with boss, outer ring inner side is provided with and closure upper end
The corresponding groove of boss, sealing exterior surface is provided with pump nozzle, and sealing exterior surface is provided with corresponding with pump nozzle size
Oil extraction mouth, sealing exterior surface be provided with dismounting groove point.
Further, the pump nozzle of the precision sealing formula bearing and oil extraction mouth number are 2 to 4.
Further, the inner ring of the precision sealing formula bearing, outer ring and closure are heat-resisting bearing steel material.
By having the beneficial effect that the technological means present invention is obtained, the precision sealing formula bearing bearing arrangement is simple, tears open
Fill easy to maintenance.Lubricating oil is filled in the case where bearing seal cover need not be dismounted, bearing daily maintenance is facilitated, is carried
The high service efficiency of bearing, extends the service life of bearing.

Specific embodiment
The present invention is described below in conjunction with example, example is served only for explaining invention, is not intended to limit this
The scope of invention.
A kind of precision sealing formula bearing, including outer ring 1, roller 2, roller cage 4, inner ring 5 and closure 6, roller 2 by
Roller cage 4 is arranged between outer ring 1 and inner ring 5, and the upper end of closure 6 is provided with boss 10, the inner side of outer ring 1 be provided with
The corresponding groove 9 of the upper end boss 10 of closure 6, the outer surface of closure 6 is provided with pump nozzle 3, and the outer surface of closure 6 is arranged
There is oil extraction mouth 8 corresponding with the size of pump nozzle 3, the outer surface of closure 6 is provided with dismounting groove point 7.By arranging the He of pump nozzle 3
Oil extraction mouth 8, it is convenient at ordinary times plus oiling maintaining, use external oil exit pipe during oiling simultaneously, when injection is oily, while excessive fuel consumption is arranged
Remove, so as to carry out effectively changing the oil of Bearing inner, facilitate bearing daily maintenance, improve the service efficiency of bearing,
Extend the service life of bearing.And the groove 9 corresponding with the upper end boss 10 of closure 6 is provided with by the inner side of outer ring 1,
This mode facilitates installation and dismounting, improves maintainability.Its quick-release fast-assembling can be facilitated by dismounting groove point 7 in addition.
To improve the efficiency for adding oiling, its maintainability is improved.The pump nozzle 3 and 8, oil extraction mouth of the precision sealing formula bearing
Number is 2 to 4.
To improve heat resistance, extend its service life, the inner ring 5 of the precision sealing formula bearing, outer ring 1 and closure 6 are
Heat-resisting bearing steel material.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
