Abstract
The utility model discloses a carrier roller bearing seat and sealing assembly which comprises a bearing seat, a bearing arranged in the seat, maze type inner and outer gaskets, a bearing seat end cover and a retaining ring used to fix the bearing seat end cover; end faces which are corresponding to the inner and outer gaskets are provided with a circular heave and a groove which are mutually nested; the bearing seat is made of nylon; an inner dust ring and an outer dust ring are also arranged between the gaskets and the bearing seat end cover; the inner and the outer dust rings are mutually nested with the bearing seat end cover. Because the nylon bearing seat and sealing assembly is shaped through injection at one time, the processing is simplified and the production cost is reduced; the bearing seat and the carrier roller are tightly matched, which avoids the phenomenon of disaligned bearing welded on both ends of the bearing, so as to realize flexible transmission, save power and improve the service life of a carrier roller shaft and a carrier roller bearing. The mutual nesting of the inner and outer dust rings and the bearing seat end cover forms quite large maze type spacing, so that the path for water and dust to go through is long, thus realizing very strong dust-proofing effect and protecting the bearing.
Description
Technical field
The utility model relates to a kind of bearing seat and seal assembly, relates in particular to a kind of roller carrier shaft bearing and seal assembly that is applied on the belt conveyer.
Background technology
Roller carrier shaft bearing and seal assembly be on the belt conveyer a consumption maximum can use parts, its quality is encircled the direct quality that influences carrying roller quality and even belt conveyer complete machine well.At present, domestic roller carrier shaft bearing and seal assembly commonly used comprises pedestal, is installed in bearing, interior exterior seal ring, end cap and back-up ring in the pedestal.This bearing seat is made by iron and steel, and two ends are welded on the carrying roller cylinder, and shortcoming is, processes loaded down with trivial details and cost is bigger, and the two ends welding also causes the phenomenon of bearing decentraction easily.Roller carrier shaft bearing that also has and the seal assembly dust hood of also setting up defences; as Chinese utility application 200320119923.6; name is called a kind of roller carrier shaft bearing as shown in Figure 1; comprise pedestal and be installed in the interior bearing of pedestal; exterior seal ring is formed in the labyrinth type; on the corresponding end face of interior exterior seal ring nested annular protrusion and groove are arranged; cooperatively interact the back in centre formation labyrinth gap; there is the water dust guard shield of annular outside the inner seal ring and pedestal large end face corresponding position; water and dust are through the gap between guard shield and the pedestal large end face; could arrive position of bearings through the labyrinth gap in the middle of the interior exterior seal ring again; this structure plays a role to the intrusion protection bearing of anti-sealing and dust; shortcoming is because the gap is little; the time that water of invading and dust stop in the gap is shorter; and out of reach water proof and dust proof effect preferably; and the material of bearing seat wherein also is an iron and steel, processes loaded down with trivial details and cost is bigger, and the two ends welding also causes the phenomenon of bearing decentraction easily.
Summary of the invention
The purpose of this utility model just is to provide roller carrier shaft bearing and the seal assembly that a kind of water proof and dust proof is effective and easy tooling cost is low.
The purpose of this utility model can realize by following measure:
The utility model it comprise bearing seat, be installed in bearing in the pedestal, the back-up ring of exterior seal ring, bearing cover and fixed bearing block end cap in the labyrinth type, on the corresponding end face of interior exterior seal ring mutually nested annular protrusion and groove are arranged, the material of described bearing seat is a nylon, end konisphere and the outer konisphere that ends in also being provided with between seal ring and bearing cover, inside and outside only konisphere is mutually nested with bearing cover.
Above-mentioned roller carrier shaft bearing and seal assembly, the material of described interior exterior seal ring, bearing cover and back-up ring is at least a to be nylon.
Above-mentioned roller carrier shaft bearing and seal assembly, the material of described bearing seat, interior exterior seal ring, bearing cover and back-up ring is at least a to be plastics.
Above-mentioned roller carrier shaft bearing and seal assembly, the material of described bearing seat, interior exterior seal ring, bearing cover and back-up ring is at least a to be rubber.
Above-mentioned roller carrier shaft bearing and seal assembly, an end of described bearing cover is provided with boss, is provided with groove on the bearing seat correspondence position.
Above-mentioned roller carrier shaft bearing and seal assembly, the other end of described bearing cover is provided with groove, ends the konisphere correspondence position outside and is provided with projection.
The utility model is owing to adopt nylined bearing seat and seal assembly, single injection-molded, manufacture simplification and reduced productive costs, bearing seat and carrying roller cylinder closely cooperate, eliminated the bearing decentraction phenomenon that has welded at iron bearing two ends, thereby realized ensuring smooth transmission, saving in power, the service life of increase roller carrier shaft and Idler bearing.The inside and outside bigger labyrinth gap of the mutually nested formation of konisphere of ending with bearing cover; water and dust are through bearing cover and outer gap of ending between the konisphere; arrive the bigger gap of exterior seal ring and bearing cover formation through interior gap of ending between konisphere and the bearing cover again; after the labyrinth gap in the middle of the inside and outside seal ring could arrive position of bearings; this structure makes the path length of water and dust process; the time that the gap makes water and powder method stop in the gap greatly is long; thereby play superpower only dirt effect, play the purpose of protection bearing.
