Abstract
The utility model relates to a single-row cylinder roller bearing with a battlement type cage. The single-row cylinder roller bearing with a battlement type cage comprises a bearing outer ring, a bearing inner ring, cylinder rollers and a cage, wherein the front end surface and the back end surface of the cage are provided with battlement type pocket holes arranged in a staggered way, cylinder rollers are arranged in the pocket holes, the cage with cylinder rollers is arranged in the bearing outer ring, and the bearing inner ring is embedded in an inner circle of the cylinder roller set, thereby constituting a set of the single-row cylinder roller bearing with the battlement type cage. In the utility model, the original base and cover of the cage are converted to an integrated battlement type cage, so that the bearing is not damaged owing to the breakage of the rivet after a long time load and impact shock, thereby prolonging the service life of the bearing. The single-row cylinder roller bearing with the battlement type cage has a reasonable design, improves the rotating speed and the carrying capacity, is easy to produce, is convenient to dismantle and install, and can prolong the average service life of the bearing by more than thirty percent. The bearing with the battlement type cage can be widely applied to machinery, mine, metallurgical industry, petrochemical industry, water power and electric power industry, etc.
Description
Technical field
The utility model relates to bearing, particularly relates to the single row roller bearing that a kind of retainer is a battlement.
Background technique
Single row roller bearing is a kind of major criterion and the non-standard component of mechanical industry; The structure of bearing has direct influence to bearing working life, product precision, machine operation efficient; Damaged single row roller bearing in the past, and be mostly rationally to cause inadequately because of the retainer structure.Comparatively general retainer is not a unitary cage at present; Be by keep stand and retainer lid to constitute together through rivet; This retainer is under the long load operation situation of bearing, and especially under vibration environment, the seat of retainer is very easily earned out with lid; To making retainer broken fully, a whole set of bearing is scrapped in advance.
The model utility content
The technical problem that the utility model will solve provides a kind of not fragile unitary cage, and can prolong the retainer of bearing in long-time load, impact shock situation following working life is the single row roller bearing of battlement.
The technological scheme that adopts is:
Retainer is the single row roller bearing of battlement, comprises bearing outer ring, bearing inner race, cylindrical roller, retainer.Described retainer one positive one anti-both ends of the surface are staggered is laid with battlement pocket hole; Pocket is equipped with cylindrical roller in the hole; The retainer that has cylindrical roller is contained in the bearing outer ring, and bearing inner race is embedded in the interior fourth contact of cylindrical roller group, and constituting a cover retainer is the single row roller bearing of battlement.
The utility model becomes one battlement retainer with original maintenance stand, lid form, can avoid bearing rivet fracture damage of bearings under long-duration load, impact shock, thereby improves bearing working life.Reasonable in design, improved rotating speed and bearing capacity, make simply, it is very convenient to dismantle, install, and the bearing mean lifetime can improve more than 30%.The bearing of this kind retainer extensively is useful in industries such as machinery, mine, metallurgy, petrochemical industry, hydraulic power.
