Abstract

The invention discloses a bearing seat for stamping twelve points, belongs to the bearing seat, and is particularly suitable for the bearing seat for a belt conveyor roller. The bearing seat for stamping twelve points comprises a stamping bearing seat; six stamping points are uniformly distributed on the upper layer of the stamping bearing seat and six stamping points are uniformly distributed on the lower layer of the stamping bearing seat; a bearing is arranged below the lower layer stamping point in the stamping bearing seat; a polyurethane V-shape seal and a steel retaining ring are sequentially arranged above the bearing from down to top; and the steel retaining ring is positioned below the lower layer stamping point and tightly clamped by the upper layer stamping point to be fixed in the stamping bearing seat. The technical scheme has the advantages of prolonging the service life of the bearing seat, reducing the frequency of changing the roller, prolonging the service cycle of the roller, reducing the labor intensity of workers and reducing the number of the seal and difficulties of processing and manufacturing.

Description

Bearing seat for stamping twelve points

Technical field

The present invention relates to a kind of bearing seat, specifically is a kind of bearing seat for stamping twelve points.Be specially adapted to belt conveyer carrying roller bearing seat.

Background technology

Show according to market research, belt conveyer is widely used in numerous areas such as mine, metallurgy, chemical industry, light industry, coal, harbour, no matter from each side such as operational throughput, haul distance, economic benefit can same train, vehicular transport contends with, become tripodia point ancient cooking vessel situation, and become various countries try to be the first the development industry, bearing seat in its key component carrying roller is big in market demand, use is wide, and the quality of its quality is directly connected to the safety in production and the economic benefit of all trades and professions.

Popular in the market DT II type series, TK75 series, TK II type series ram axle bearing, wherein DT II type series and TK75 series are withdrawn from the market gradually because of complex structure, have only TK II type series all the fashion on market, and it adopts two plastic seals to seal, its drawback is that protection against dust, fire retardancy are bad, and mine safety is had certain hidden danger.

Summary of the invention

For solving the problems of the technologies described above, the invention provides a kind of bearing seat for stamping twelve points that the belt conveyer carrying roller is used that is suitable for.

The present invention realizes with following technical scheme: a kind of bearing seat for stamping twelve points, comprise the ram axle bearing, on the ram axle bearing, divide two layers of each uniform six punching press point up and down, in the ram axle bearing, below lower floor's punching press point bearing is housed, bottom-up polyurethane v-seal and the steel retaining ring of being equipped with successively on bearing; The following chucking by upper strata punching press point that steel retaining ring is positioned at lower floor's punching press point is fixed on the ram axle bearing.

Technique scheme, the polyurethane v-seal has improved leak free reliability and resistance to abrasion; The shock resistance that the steel ring washer has improved bearing seat as outer closure, pressurize, dustproof, fire resistance; Two layers of uniform 12 punching press point up and down, six punching press point fixed type bearings of lower floor, six the punching press point fixing seals in upper strata and steel ring washer.Guarantee carrying roller during use, the phenomenon of bearing defective can not take place, accomplished product non-maintaining requirement throughout one's life.

The invention has the beneficial effects as follows: improved the service life of bearing seat, reduced the frequency of changing carrying roller, the operating cycles that prolongs carrying roller; And then alleviate labor strength; Reduced the difficulty of leak free quantity and processing and manufacturing simultaneously.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the A-A section-drawing of Fig. 1.

Among the figure: 1, ram axle bearing, 11. upper strata punching press points, 12, lower floor's punching press point, 2, steel retaining ring, 3, the polyurethane v-seal, 4, bearing.

The specific embodiment

As depicted in figs. 1 and 2, bearing seat for stamping twelve points has a ram axle bearing 1, divides two layers of each uniform six punching press point up and down on ram axle bearing 1, and six punching press points 12 of lower floor are used for fixing bearing 4, six the punching press points 11 in upper strata are used for fixing polyurethane v-seal 3 and steel ring washer 2.Bearing 4 is housed below lower floor's punching press point 12 in ram axle bearing 1, and bearing 4 is deep groove ball bearings that size matches with the inner chamber of ram axle bearing 1.Bottom-up polyurethane v-seal 3 and the steel retaining ring 2 of being equipped with successively on bearing 4; The end face that bearing 4 is axial and the bottom of ram axle bearing 1 contact, and the open end of another axial end and polyurethane v-seal 3 contacts.The closed end of polyurethane v-seal 3 and steel ring washer 2 contact.The following chucking by upper strata punching press point 12 that steel retaining ring 2 is positioned at lower floor's punching press point 12 is fixed on ram axle bearing 1.The arcuate structure that steel ring washer 2 adopts the middle part to raise up, the closed end of bottom surface and polyurethane v-seal contacts and forms the gap, has further improved sealing property.
