Abstract
The utility model relates to a novel low-moment and mute household appliance bearing, which comprises an outer ring, an inner ring, a steel ball, a retainer and a sealing ring, and is characterized in that the steel ball is arranged between a rollaway nest of the outer ring and a rollaway nest of the inner ring, the retainer is arranged between the outer and the inner rings and corresponds to the steel ball, and the outer side surface between the outer and the inner rings is respectively provided with the sealing ring; therefore, the outer diameter of the outer ring can be maintained, the inner diameter of the rollaway nest of the outer ring can be reduced, the outer diameter of the rollaway nest of the inner ring can be reduced, the diameter of the steel ball can be reduced, the diameter of the steel ball is 3.175 mm, and the diameter of a gyration center of the steel ball is 13 mm. The novel low-moment and mute household appliance bearing has the advantages that low moment, low noise and low energy consumption can be realized.
Description
Technical field
The utility model relates to a kind of household electric appliance small-sized deep groove ball bearing, particularly a kind of novel low moment, quiet household electrical appliances bearing.
Background technique
Household electric appliance have entered common people's daily life at present, along with development of technology is also more and more higher to the requirement of household electric appliance, require more low noise of household electric appliance, save energy and reduce the cost more and also become a trend, bearing is the core part of mechanical part in the household electric appliance, the noise of bearing and energy consumption also become a direction of bearing technology progress, conventional domestic electrical equipment such as air-conditioning, washing machine, vacuum cleaner etc. all are to be driven by micro-machine, these motors are owing to use that to vibrate little noise in family's environmental requirement low, also require noise low so be used for the bearing of these household electric appliance, and common bearing just can't satisfy the requirement of low noise, therefore demands inventing the bearing that a kind of household electric appliance that can reduce noise are used urgently.
Summary of the invention
The purpose of this utility model is that plain bearing is used in the excessive existing problem of noise in the household electric appliance in the solution prior art, a kind of novel low moment is provided, quiet household electrical appliances bearing, the utility model designs a kind of novel low moment, quiet household electrical appliances bearing, comprise the outer ring, inner ring, steel ball, retainer and seal ring, it is characterized in that: steel ball is between the raceway and inner ring raceway of outer ring, retainer is positioned at the outer ring, between the inner ring with respect to steel ball, in the outer ring, seal ring is respectively arranged on the outer side surface between the inner ring, the external diameter that keeps the outer ring, reduce the internal diameter of outer ring raceway, reduce the external diameter of inner ring raceway, reduce the diameter of steel ball, the diameter of steel ball is 3.175 millimeters, and the gyration center diameter of steel ball is 13 millimeters.The utility model has the advantages that and realized low moment, low noise, low energy consumption.
Description of drawings
Fig. 1 is the prior art constructions schematic representation, and accompanying drawing 2 is a structural representation of the present utility model,
Comprise outer ring 1, inner ring 2, steel ball 3, retainer 4 and seal ring 5 among the figure, it is characterized in that: steel ball 3 is between the raceway and inner ring 2 raceways of outer ring 1, retainer 4 between outer ring 1, inner ring 2 with respect to steel ball 3, on the outer side surface between outer ring 1, the inner ring 2, seal ring 5 is arranged respectively, keep the external diameter of outer ring 1, reduce the internal diameter of outer ring 1 raceway, reduce the external diameter of inner ring 2 raceways, reduce the diameter of steel ball 3, the diameter of steel ball 3 is 3.175 millimeters, and the gyration center diameter of steel ball 3 is 13 millimeters.
Reduce the diameter of steel ball 3.With household electric appliance bearing model commonly used is 608 bearings, and its boundary dimension is: outer diameter D=22mm, internal diameter=8mm, the inner steel ball size of width B=7mm. conventional structure bearing are 3.969, and steel ball number is 7, and dynamic load rating is 3.25KN.And the load that bears at household electric appliance applying working condition lower bearing is less than 0.1% of bearing rated load, because very little of the rated load of the relative bearing of load that bears of bearing, the contact stress of inner steel ball of bearing and bearing race is also very little, has the life-span of endless according to theoretical this bearing of bearing life.Steel ball size and steel ball gyration center according to theoretical bearing operation moment of bearing and bearing directly hold the positive correlation function, under the constant prerequisite of bearing boundary dimension, reduce steel ball size, reduce flywheel moment and noise level that steel ball gyration center diameter can obviously reduce bearing, to bearing inside according to the low moment of bearing and low noise design object function as bearing, by repeated calculation and optimization, new model utility bearing major parameter such as steel ball size have been determined, the steel ball swing diameter, the load-carrying ability of having taken into account bearing simultaneously has sufficiently high deposit, obviously reduce by optimizing steel ball size and steel ball gyration center footpath, with 608 bearings is example, steel ball size reduces to 3.175mm by 3.969mm, the gyration center diameter reduces to 13mm by 15mm, the flywheel moment of the bearing of new model utility has only 25% of original structure, thereby realized low moment, the purpose of low energy consumption, simultaneously in the bearing noise measuring, noise level reduces by 2 more than the decibel under the same process prerequisite, really realized low moment, low noise, the model utility purpose of low energy consumption.
Claims (1)
1, a kind of novel low moment, quiet household electrical appliances bearing, comprise outer ring, inner ring, steel ball, retainer and seal ring, it is characterized in that: steel ball is between the raceway and inner ring raceway of outer ring, retainer between outer ring, inner ring with respect to steel ball, seal ring is respectively arranged on the outer side surface between outer ring, the inner ring, the external diameter that keeps the outer ring, reduce the internal diameter of outer ring raceway, reduce the external diameter of inner ring raceway, reduce the diameter of steel ball, the diameter of steel ball is 3.175 millimeters, and the gyration center diameter of steel ball is 13 millimeters.
