Abstract
The utility model relates to a bearing, and in particular relates to a double-row full-complement snap ring type cylindrical roller bearing. A plurality of rollers are clamped between an inner ring and an outer ring of the double-row full-complement snap ring type cylindrical roller bearing, and a gap existing between the inner ring and the outer ring of the bearing is provided with a sealing ring. The internal diameter part and the external diameter part of the whole rubber sealing ring of the double-row full-complement snap ring type cylindrical roller bearing provided by the utility model are both in contact with the bearing and no gap exist between the internal diameter part and the external diameter part, so that an extremely good sealing effect can be achieved. Dust, fog, rainwater and other matters outside the bearing cannot enter the inside of the bearing, lubricating grease added into the bearing cannot flow out either, and therefore, the bearing has the advantages of long service life and simplicity in maintenance and management. When the bearing operates at low speed or intermediate speed for a long term, the lubricating grease has to be replenished, and the plastic sealing ring is also simple in dismounting by adopting a simple tool such as a screwdriver.
Description
Technical field
What the utility model patent related to is bearing, a kind of roller bearing of more specifically saying so.
Background technique
Full-complement cylinder roller bearing is compared maximum difference with common cylindrical roller be that the roller quantity that is equipped with is maximum, do not have the retainer of isolating between the roller.Under the situation of same internal diameter and width, full-complement cylinder roller bearing has lower depth of section usually, and bearing has high radially bearing capacity, and can save the space.Thereby be widely used in the speed reducer and the handling machinery industry of automobile gearbox, engineering machinery.
The bearing structure of existing double-row full-complement band dust cover is as shown in Figure 2; Its roller bearing is made up of an outer ring 1, two inner rings 2 and several cylinders roller 4, two dust covers 6, two spring rings 5, because what adopt is the metal dust cover; Though have dustproof effect; But can not prevent fog, and because gapped between dust cover and outer ring, the inner ring, the lubricant grease of bearing inside there is spillover.Simultaneously, because dust cover is that car system forms, manufacturing efficiency is lower, and cost is higher, and is unfavorable for producing in enormous quantities.
The model utility content
The purpose of the utility model is to provide a kind of double-row full-complement clasp type roller bearing of high sealing degree.
The purpose of the utility model realizes through following approach: a kind of double-row full-complement clasp type roller bearing, clamped some rollers between bearing inner race and outer ring, and on the inner ring of bearing and the outer ring gap seal ring is installed.
Further, the seal ring external diameter becomes interference fit to be connected with outer ring raceway.
Further, the inner-diameter portion whose of seal ring is a convex, on the interior external diameter of bearing inner race a groove is arranged, the internal diameter protuberance of seal ring embeds on the interior external diameter of inner ring.
Further, the inner ring of bearing is two, two inner ring connecting parts are fixed through clasp.
Whole rubber seal internal diameter, the outer radius portion of the utility model double-row full-complement clasp type roller bearing all contacts very close to each other with bearing, can reach good seal action like this.Materials such as the dust of bearing outside, mist, rainwater can not get into bearing inside, and the lubricating grease that adds in the bearing also can not flow out, thereby this class bearing has more long service life, the maintenance management characteristic of simple.As when low speed or the middling speed long-time running, must supplemental lubrication fat, the dismounting of rubber seal is also very simple, only needs to use simple tools such as screw-driver.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain:
Fig. 1 is the utility model structural representation;
Fig. 2 is existing double-row full-complement bearing with retaining shield structural representation;
Among the figure, outer ring 1, inner ring 2, seal ring 3, roller 4, spring ring 5, dust cover 6, clasp 7.
Embodiment
As shown in Figure 1; The utility model double-row full-complement clasp type roller bearing, 1 of bearing inner race 2 and outer ring have clamped some rollers 4, on the inner ring 2 of bearing and 1 gap, outer ring seal ring 3 are installed; Seal ring 3 external diameters become interference fit to be connected with outer ring 1 raceway; The inner-diameter portion whose of seal ring 3 is a convex, on the interior external diameter of bearing inner race 2 groove is arranged, and the internal diameter protuberance of seal ring 3 embeds on the interior external diameter of inner ring 2.
Inner ring 2 has two, and two inner ring 2 connecting parts are fixing through clasp 7, and it is simple in structure, connects reliably, and suits to produce beautiful shape in enormous quantities.
