Abstract
The utility model discloses an improved four-line cylindrical roller bearing, mainly composed of an outer ring, an outer retaining ring, a middle retaining ring, a middle spacing ring, a cylindrical roller, an inner ring and a keeping rack. The improved four-line cylindrical roller bearing comprises two double-roller outer rings and two single-line inner rings and the outer retaining rings are mounted at the two sides of the two outer rings, the middle retaining ring is placed between the two outer rings, a middle spacing ring is mounted between the two rollers at the inner side of the outer ring, the keeping rack is mounted between the outer ring and the inner ring of each line and a line of cylindrical roller is mounted in each keeping rack. The inner end surface of the outer retaining ring and the outer side of the middle retaining ring are designed into arc. The improved four-line cylindrical roller bearing prevents the bearing parts stress concentration from generating and relatively increases the bearing life and its radial loading capability.
Description
Technical field the utility model relates to technical field of bearings, and concrete a kind of being applicable to that relate to requires at a high speed and a kind of improved four-line column roller bearing of high-precision roll bearing.
The background technique four-line column roller bearing is a kind of separable type bearing.Its inside and outside circle is linear the contact with roller, and friction factor is little, and it is bigger to bear radial capacity, and the cleaning of bearing, inspection and dismounting are all very convenient.This class bearing can obtain higher processing precision, the friction of bearing itself is low than other bearing in addition, so four-line column roller bearing is specially adapted to require at a high speed and high-precision roll, as wire mill, the supporting of the cold and hot milling train of bar and shape mill and thin plate, blooming mill etc.The outer ring structure of traditional four-line column roller bearing is provided with fixedly centre rib and oil cavity, the easy like this generation that causes bearing parts to be concentrated, and when bearing parts heat-treatment quenching, grinding, oil duct becomes the formation of crack that may crack; In addition, bearing is in operation process, and the edge of bearing parts is easy to produce stress, and these all make bearing parts be easy to damage, and reduce the working life of bearing.
The defective that summary of the invention exists in view of prior art, the purpose of this utility model are that a kind of a kind of improved four-line column roller bearing that can reduce the damage of bearings risk and improve its life-span and radial capacity relatively will be provided.
For achieving the above object, the technical solution that the utility model adopted is: a kind of improved four-line column roller bearing, mainly form by outer ring, outer back-up ring, guide ring, middle spacer ring, cylindrical roller, inner ring and retainer.Described a kind of improved four-line column roller bearing has two outer ring with double raceways and two single-row inner rings, both sides, two outer rings are equipped with outer back-up ring, lay guide ring between two outer rings, between inboard two raceways in outer ring middle spacer ring is installed, between every row outer ring and the inner ring retainer is installed, the columna roller is installed in each retainer.
The interior edge face of described outer back-up ring is designed to arc.
The described guide ring outside is designed to arc.
The advantage of described a kind of improved four-line column roller bearing is: 1, changes the bearing ring structure, cancelled the fixedly centre rib of outer ring conventional construction, need not the processing and lubrication oil duct, and the generation of having avoided bearing parts stress to concentrate reduces the damage of bearings risk; 2, the outer ring of new structure is not owing to there is oil duct, and the formation of crack that may crack when having avoided part heat-treatment quenching, grinding improves bearing life relatively; 3, behind the bearing outer ring cancellation centre rib, thrust load has been avoided bearing in the outer ring, can improve its rigidity relatively and bear radial capacity; 4, the interior edge face architecture advances of two end faces of bearing guide ring and outer back-up ring has reduced bearing in operation process, and bearing parts produces the possibility of edge stress, has reduced the bearing parts probability of damage.
