Abstract
The utility model relates to the technical field of aligning roller bearings, and in particular relates to a stamping retainer aligning roller bearing with a novel structure. A retainer is arranged between a ring and an inner ring; a roller is positioned on the retainer which is provided with a partition ring, a first guide surface and a second guide surface; a cut slope is positioned between the first guide surface and the second guide surface; and the retainer is provided with a fore shaft. The stamping retainer aligning roller bearing of the novel structure has the beneficial effects that the cut slope is added at the fore shaft, and the height of the fore shaft is increased so as to prevent the contact of the cut slope and a roller; the service life is prolonged; meanwhile the aim of increasing the storage amount also can be achieved, so that a roller path can be lubricated well; the guide surfaces are arranged at two sides of the cut slope, the roller running stability is increased; and roller abrasion is reduced.
Description
Technical fieldThe utility model relates to the selfaligning roller bearing technical field, specifically a kind of pressing cage selfaligning roller bearing of new structure.
Background techniqueAlong with field fast developments such as domestic and international milling train, blower, mine, harbour, engineering machinery, need to improve the manufacturing efficiency of machinery, for the high-mechanic that adapts to equipment, high reliability, at a high speed requirement, certainly will require the bearing of high speed, high-mechanic, high reliability to match; At present, the selfaligning roller bearing of domestic use, most of copper cage that adopts, the employing steel plate pressing cage that had in several years, but rotating speed can not be too high.Rotating speed is too high, and the guide ring parts depreciation is serious.Research and develop a kind of selfaligning roller bearing that has pressing cage of new structure, the bearing with high-mechanic, highi degree of accuracy, high reliability becomes the task of top priority for this reason.
Summary of the inventionIn view of the defective that prior art exists, the purpose of this utility model provides a kind of pressing cage selfaligning roller bearing of new structure.
For achieving the above object, the technical solution that the utility model adopts is: a kind of pressing cage selfaligning roller bearing of new structure, be provided with retainer between outer ring and inner ring, roller is positioned on the retainer, retainer is provided with middle spacer ring, described retainer is provided with first guiding face and second guiding face, cuts the slope between first guiding face and second guiding face, and retainer is provided with fore shaft.
Described fore shaft height is higher than roller diameter 30%.
The gyration center of described retainer is positioned at the center of circle of the circle that the point of contact at fore shaft height point, roller and retainer two ends determines.
Described domatic and the roller bus of cutting the slope is tangent.
A kind of pressing cage selfaligning roller bearing of new structure, its beneficial effect is: increase at the fore shaft place and cut the slope, and increase the fore shaft height, avoid cutting contacting of slope and roller, increase the service life, can also reach the purpose of increase trapped fuel amount simultaneously, thereby better lubricate raceway, be provided with guiding face cutting sloping both sides, increase the smoothness of roller operation, reduce the wearing and tearing of roller.
