Abstract
The utility model relates to a sealing split full complement cylindrical roller bearing, solving the sealing problem of a split bearing under the severe working environment. The sealing split full complement cylindrical roller bearing comprises an outer ring, an inner ring, fastening rings and a cylindrical roller, wherein the outer ring is provided with double retaining sides, a sealing groove is arranged on each of both end surfaces of the outer ring, the outer ring is split with an apex angle in a theta shape, the split surface of the inner ring is split with an angle of alpha with the axial line, two halves of the inner ring are clamped by the two fastening rings and fastened by screws, and a sealing convex groove is arranged on one end surface of each fastening ring. After the bearing is assembled, the sealing convex grooves on the end surfaces of the fastening rings and the sealing grooves on the end surfaces of the outer ring form labyrinth sealing. The sealing split full complement cylindrical roller bearing has the advantages that greater radial load can be borne, and the reliability is high; and compared with an open split bearing, the sealing split full complement cylindrical roller bearing is higher in use reliability and longer in service life.
Description
Technical field
The utility model relates to a kind of sealing technique of split type full-complement cylinder roller bearing
Background technique
Mostly domestic present split bearing is open bearing, does not have sealing or uses the colloid seal ring, and Environmental Conditions is very limited.In some dusts, bad working environments such as corrosive deposit is seriously polluted, temperature is high, pressure is big, bearing early damage occurs through regular meeting.
The model utility content
The sealing problem of split type full-complement cylinder roller bearing provides a kind of new split bearing sealing solution to the utility model under bad working environment in order to solve.
The problem that the utility model solves realizes through following technological scheme: sealing split type full-complement cylinder roller bearing is to be made up of outer ring, inner ring, fastening ring, cylindrical roller; Two ribs have been done in the outer ring; On the both ends of the surface of outer ring, sealed groove is arranged, it is θ shape subdivision that drift angle is adopted in the outer ring; The inner ring split surface adopts and becomes α angle subdivision with axis, and the two halves inner ring is clamped by two fastening rings, and fastening with screw.Fastening ring one end face has the sealing tongue.After bearing assembled, sealing tongue on the fastening ring end face and the sealed groove on the cycle surface formed labyrinth sealing.
The utility model is through the sealing tongue tabling on outer ring sealed groove and the fastening ring; Can keep bearing to roll indoor oiling agent; Prevent to pollute impurity and get in bearing inside and the oiling agent, sealing split type full-complement cylinder roller bearing can bear bigger radial load; Reliability is high, has higher operational safety and longer working life with respect to the open type split bearing.
