Abstract
The utility model relates to a supporting roller, which is composed of a supporting roller body and bearings. Supporting roller supporting covers are welded in the inner parts of both ends of the supporting roller body, and short shafts are welded in the centers of the supporting roller supporting covers. Tightly fixing sleeves for of the bearings are arranged on the short shafts, and an assembly is composed of the bearings, an inner sealing ring which is arranged in a bearing body, and an outer sealing ring which is also arranged in the bearing body. The utility model has the advantages of small rotation resistance force, and good sealing property. Because lubricating oil can be often filled in, the bearings has the advantage of long service life. Once the bearings are damaged, replacement is easy.
Description
The utility model relates to a kind of carrying roller of band conveyor.
Traditional carrying roller generally is equipped with bearing body at carrying roller body two ends, and the bearing body center is installed with major axis, and bearing is housed on the bearing body, though this idler structure is simple, when processing and installation, the concentricity of bearings at both ends is relatively poor, and maintenance difficult.
The purpose of this utility model is: the problem that exists in installing and keeping in repair at traditional carrying roller designs a kind of separation and sealed oil-filling type supporting roller
The purpose of this utility model is achieved in that a kind of separation and sealed oil-filling type supporting roller, hold by carrying roller body, roller and to form, it is characterized in that: inside, described carrying roller body two ends is welded with supporting cover, carrying roller supporting cover central authorities are welded with minor axis, the bearing adapter sleeve is sleeved on the minor axis, and bearing is housed on the bearing adapter sleeve, and bearing body is housed on the bearing, between bearing body and the carrying roller body exterior seal ring is housed, is provided with inner seal ring between bearing body and the bearing adapter sleeve.
Advantage of the present utility model is: rotary resistance is little, because the good airproof performance of bearing, and can often inject lubricating oil, and the long service life of bearing, bearing is in case damage very easily replacing.
Fig. 1 is the utility model example structure scheme drawing.
Below in conjunction with accompanying drawing the utility model embodiment is further described.
As seen from Figure 1: inside, carrying roller body 1 two ends is welded with carrying roller supporting cover 2, carrying roller supporting cover 2 central authorities are welded with minor axis 3, bearing adapter sleeve 4 is sleeved on the minor axis 3, bearing 5 is housed on the bearing adapter sleeve 4, bearing body 6 is housed on the bearing 5, between bearing body 6 and the carrying roller body 1 exterior seal ring 7 is housed, between bearing body 6 and the bearing adapter sleeve 4 inner seal ring 8 is housed.In the present embodiment, minor axis 3 is interior big outer little pyramidal structure, the hole at bearing adapter sleeve 4 centers is identical with the tapering of minor axis 3, and bearing adapter sleeve 4 is the two-stage step, and each step all is equipped with bearing 5, bearing body 6 also is a step, and cooperate with corresponding bearing 5, exterior seal ring 8 is two concavo-convex cooresponding labyrinth type nylon rings, wherein leans on a slice and carrying roller body 1 synchronization action of the inside, the a slice on outer limit and bearing body 6 close fits are equipped with zerk 9 at center, bearing body 6 end.
The utility model in use, owing to can be bearing 5 filling lubricating oils often by zerk 9, can prolong bearing service life, in case bearing 5 damages, can be together with bearing adapter sleeve 4, bearing 5, bearing body 6, inner seal ring 8, a slice nylon ring of exterior seal ring 7 is pulled out, and changes one easily and contains the new assembly that above-mentioned part is formed.
