Abstract
The utility model relates to a four-layer sealed deep groove ball bearing for a vibration motor, which comprises an inner race, an outer race, a first sealing cover, a second sealing cover, a third sealing cover, a fourth sealing cover, a plurality of steel balls and a retaining rack. The outer race is arranged outside the inner race. The first sealing cover, the second sealing cover, the third sealing cover and the fourth sealing cover are sequentially arranged between the inner race and the outer race from top to bottom. Greases are respectively filled in cavity bodies which are formed amongthe sealing covers, a raceway is formed between the second sealing cover and the third sealing cover, and the plurality of steel balls are uniformly arranged in the raceway by the retaining rack. Thefour-layer sealed deep groove ball bearing adopts four-layer sealing and one-time grease filling to ensure permanent lubrication, which brings about great convenience for a main engine plant to provide maintenance service for a user, shortens the maintenance time and reduces the maintenance cost as well.
Description
Technical field
The utility model relates to bearing, particularly relates to a kind of vibrating motor four-layer seal deep groove ball bearing.
Background technique
To carry out carrying out sorting to all kinds of powder in building building cement, medicine, food service industry by granule size.The powder stock of building building cement decorative product for example, powder class raw materials such as the pharmacy powder of pharmaceuticals industry or the flour of food service industry, ground rice all need carry out vibration screening, the original structure vibrating motor adopts the double-row self-aligning roller bearing (see figure 1), and this class bearing is used to have the big machinery of lubricated series comparatively suitable.For example steel industry, casting industry etc. have sealing lubrication system heavy machinery, but for light industry system, because the unlubricated system of main frame, can only lean on bearing grease lubricated, and this class bearing does not have seal arrangement, cause two more serious vital wounds: 1, bearing very easy loss of grease under vertical use and condition in continuous shaking, therefore need every month increase grease once, bring many inconvenience to main engine factory and use factory; 2, bearing is under comparatively abominable operating conditions, and dust and foreign material are all invaded bearing race, therefore causes bearing wear, and the life-span shortens greatly, and therefore selfaligning roller bearing has been difficult to use in this kind equipment.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide a kind of vibrating motor four-layer seal deep groove ball bearing for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of vibrating motor four-layer seal deep groove ball bearing, it is characterized in that, comprise inner ring, be located at the outer outer ring of inner ring, first sealing cover, second sealing cover, the 3rd sealing cover, the 4th sealing cover, several steel balls and retainer, described first sealing cover, second sealing cover, the 3rd sealing cover and the 4th sealing cover are located between the inner ring outer ring from top to bottom successively, all annotate in the cavity that constitutes between each sealing cover and be provided with grease, constitute raceway between described second sealing cover and the 3rd sealing cover, described several steel balls evenly are located in the raceway by retainer.
Annotate the grease that is provided with 100% cavity volume in the cavity that constitutes between described first sealing cover and second sealing cover.
Annotate the grease that is provided with 25%～35% cavity volume in the cavity that constitutes between described second sealing cover and the 3rd sealing cover.
Annotate the grease that is provided with 50%～80% cavity volume in the cavity that constitutes between described the 3rd sealing cover and the 4th sealing cover.
Described first sealing cover, second sealing cover and the 3rd sealing cover are the noncontact seal lid.
Described the 4th sealing cover is the contact seal lid.
Compared with prior art, the utlity model has following advantage:
1, disposable greasing guarantees lifelong lubricating, so do not need every month to add grease, greatly facilitates the maintenance service of main engine factory for the user, has shortened engineering time, and has saved maintenance cost;
2, adopt four-layer seal, fill with grease in the interlayer of the first layer and the second layer, first layer prevents that dust from directly invading bearing internal raceways chamber, there is petrol starvation as bearing internal raceways working room contingency, the upper strata grease can progressively infiltrate the working room and replenish grease, is full of grease between the 3rd, the 4th layer and can stops grease to escape leak bearing race working room.
3, raceway ditch curvature is dwindled, prevent that axial string momentum is bigger than normal so the use of the motor vertical that suits has overcome former common ball bearing and born the relatively poor shortcoming of axial impact loading ability;
4, prolong more than one times than former selfaligning roller bearing working life.
Description of drawings
Fig. 1 is the structural representation of existing double-row self-aligning roller bearing;
Fig. 2 is a structural representation of the present utility model.
Wherein: 1-inner ring, 2-outer ring, 3-first sealing cover, 4-second sealing cover, 5-the 3rd sealing cover, 6-the 4th sealing cover, 7-steel ball, 8-retainer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of vibrating motor four-layer seal deep groove ball bearing, comprise inner ring 1, be located at the outer ring 2 outside the inner ring 1, first sealing cover 3, second sealing cover 4, the 3rd sealing cover 5, the 4th sealing cover 6, several steel balls 7 and retainer 8, described first sealing cover 3, second sealing cover 4, the 3rd sealing cover 5 and the 4th sealing cover 6 are located between inner ring 1 outer ring 2 from top to bottom successively, all annotate in the cavity that constitutes between each sealing cover and be provided with grease, constitute raceway between described second sealing cover 4 and the 3rd sealing cover 5, described several steel balls 7 evenly are located in the raceway by retainer 8.
Described first sealing cover 3 prevents dust rubbish intrusion bearing working chamber, annotates the grease that is provided with 100% cavity volume in the cavity that constitutes between first sealing cover 3 and second sealing cover 4; Annotate the grease that is provided with 25%～35% cavity volume in the cavity that constitutes between described second sealing cover 4 and the 3rd sealing cover 5; Annotate the grease that is provided with 50%～80% cavity volume in the cavity that constitutes between described the 3rd sealing cover 5 and the 4th sealing cover 6, prevent that bearing working chamber grease runs off; Described first sealing cover 3, second sealing cover 4 and the 3rd sealing cover 5 are the noncontact seal lid; Described the 4th sealing cover 6 is the contact seal lid, reveals loss bearing outside with absolute assurance bearing internal grease.
The utility model improves bearing rigidity greatly than 1.5～1.8 times of former common deep groove ball bearing width widen, with Shi Kuandu is identical with self-aligning roller bearing, is convenient to replace former self-aligning roller bearing.
