Abstract
The utility model relates to a low-torque, high-efficiency and energy-saving deep groove ball bearing. The deep groove ball bearing comprises an inner ring, an outer ring and steel balls positioned between the inner ring and the outer ring, wherein retainers are also arranged between the inner ring and the outer ring; the steel balls are positioned in and retained by the retainers; a sealing sheet covers a part between the inner ring and the outer ring and comprises a sealing ring; a convex inner lip ring is arranged on the inner edge of the back of the sealing ring; a convex outer lip ring is arranged on the outer edge of the back of the sealing ring; a metal sealing sheet is sandwiched between the inner lip ring and the outer lip ring; and a plurality of concave ventilation ports are uniformly distributed on the outer lip ring. The ventilation ports are formed on the outer lip ring, and particularly a gas discharge notch is formed on the side of the sealing ring, so that gas in a bearing can be discharged from the ventilation ports and the gas discharge notch during running, temperature in the bearing can be reduced, air resistance is reduced, and the aim of reducing torque is fulfilled.
Description
Technical field
The utility model relates to the energy-efficient deep groove ball bearing of a kind of low moment of torsion.
Background technique
Existing bearing generally comprises inner ring, outer ring and the steel ball between inner ring and outer ring, also is provided with retainer between inner ring and the outer ring, and steel ball is positioned at retainer and is kept by retainer, is covered with diaphragm seal between inner ring and the outer ring; Diaphragm seal comprises seal ring, the lobed epipharynx ring of the inner edge at the seal ring back side, and the lobed outer lip ring of the outer rim at the seal ring back side accompanies the metal mounting between epipharynx ring and the outer lip ring, and diaphragm seal plays the dust-tight effect.It is in the shortcoming that exists: bearing can suck ambient atmos between the inner ring and outer ring of bearing in the high-speed rotation process; But because the seal action of diaphragm seal; Gas is difficult to discharge outside the bearing; Temperature is higher in the bearing when therefore moving, resistance of air is bigger, thereby has increased moment of torsion and friction, and also reduce working life.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing bearing, the utility model provides a kind of energy-efficient deep groove ball bearing of low moment of torsion of moment of torsion and friction when reducing operation.
The technological scheme that the utility model solves its technical problem is: the energy-efficient deep groove ball bearing of a kind of low moment of torsion; Comprise inner ring, outer ring and the steel ball between said inner ring and outer ring; Also be provided with retainer between described inner ring and the outer ring; Described steel ball is positioned at described retainer and is kept by described retainer, is covered with diaphragm seal between described inner ring and the outer ring;
Described diaphragm seal comprises seal ring, the lobed epipharynx ring of the inner edge at the said seal ring back side, and the lobed outer lip ring of the outer rim at the said seal ring back side accompanies the metal mounting between described epipharynx ring and the outer lip ring;
Described outer lip ring is provided with several recessed ventilation mouths; Described ventilation mouth is evenly distributed on the described outer lip ring.
Further, the side of said seal ring also offers an exhaust breach.
The beneficial effect of the utility model is: owing on the outer lip ring, be provided with ventilation mouth; Especially the side of seal ring also offers an exhaust breach; Therefore bearing gas in the bearing when operation can be discharged in ventilation mouth and exhaust breach; Therefore can reduce the temperature in the bearing, and reduce the resistance of air, reach the purpose that reduces moment of torsion.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the diaphragm seal of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
With reference to Fig. 1, Fig. 2; The energy-efficient deep groove ball bearing of a kind of low moment of torsion; Comprise inner ring 1, outer ring 2 and the steel ball 3 between said inner ring 1 and outer ring 2; Also be provided with retainer 4 between described inner ring 1 and the outer ring 2, described steel ball 3 is positioned at described retainer 4 and is kept by described retainer 4, is covered with diaphragm seal 5 between described inner ring 1 and the outer ring 2.
Described diaphragm seal 5 comprises seal ring, the lobed epipharynx ring 6 of the inner edge at the said seal ring back side, and the lobed outer lip ring 7 of the outer rim at the said seal ring back side accompanies metal mounting 8 between described epipharynx ring 6 and the outer lip ring 7.
Described outer lip ring 7 is provided with several recessed ventilation mouths 9; Described ventilation mouth 9 is evenly distributed on the described outer lip ring 7.The side of said seal ring also offers an exhaust breach 10.
Owing on outer lip ring 7, be provided with ventilation mouth; Especially the side of seal ring also offers an exhaust breach 10; Therefore bearing gas in the bearing when operation can be discharged in ventilation mouth 9 and exhaust breach 10; Therefore can reduce the temperature in the bearing, and reduce the resistance of air, reach the purpose that reduces moment of torsion.
