Abstract
The invention discloses a kind of single row roller bearing, including bearing body, retainer, cylindrical roller, bearing outer ring, the first rib, the second rib, bearing inner race and dust-proof end cap, the bearing body includes bearing outer ring and bearing inner race；Retainer is fixed with around the bearing inner race；Cylindrical roller is provided with the retainer；The periphery of the cylindrical roller is provided with bearing outer ring；One end of the bearing inner race is fixedly connected by dust-proof end cap with one end of bearing outer ring；The other end of the bearing inner race is fixedly connected by dust-proof end cap with the other end of bearing outer ring.The advantageous effect of the invention is that the contact line between the convenient and modified roller of installation and removal and raceway is good to the effect for reducing stress concentration.
Description
Technical field
The invention belongs to technical field of bearings, and in particular to a kind of single row roller bearing.
Background technology
China is one of country of earliest invention rolling bearing in the world, in Chinese Ancient Books, the structure on axle bearing
Make early on the books.From archaeology historical relic with terms of data, the most ancient bearing with modern rolling bearing structure blank of China, appearance
In modern Shanxi Province's Yongji County Xue Jiaya villages of B.C. 221~207 years (Qin Dynasty).After founding of New, this century seven is particularly
Since the ten's, under the powerful promotion of reform and opening-up, bearing industry enters a brand-new high-quality fast-developing period and exists
17th century end, C. watts of Lip river of Britain manufactures and designs ball bearing, and P. on probation and Britain irrigates think of acquirement ball on postal car
The patent of bearing.18 end of the centurys H.R. hertz of Germany delivers paper on ball bearing contact stress.In hertz achievement
On the basis of, German R. applies Trebek, the A. pa nurse Glenns et al. of Sweden have carried out substantial amounts of experiment, to developing rolling bearing
Design theory and Calculation of Fatigue Life contribute.Then, the N.P. Dinko Petrov application newton law of viscosity meters of Russia
Calculate bearing friction.Discovery of the O. Reynolds of Britain to Bristol has carried out mathematical analysis, is derived Reynolds equation, and stream has been established from this
The basis of body hydrodynamic lubrication theory.Founding the state over 50 years, Chinese bearing work obtains remarkable achievement already.
Current bearing, mounts and dismounts the contact line between inconvenient and modified roller and raceway to reducing stress collection
In effect it is poor.
Therefore, a kind of single row roller bearing is invented to be very necessary.
The content of the invention
It is current to solve to propose in above-mentioned background technology it is an object of the invention to provide a kind of single row roller bearing
Bearing, mount and dismount contact line between inconvenient and modified roller and raceway to reducing the effect difference of stress concentration
Problem.
To achieve the above object, the present invention provides following technical solution：A kind of single row roller bearing, including bearing sheet
Body, retainer, cylindrical roller, bearing outer ring, the first rib, the second rib, bearing inner race and dust-proof end cap, the bearing body
Including bearing outer ring and bearing inner race；Retainer is fixed with around the bearing inner race；Cylinder is provided with the retainer
Roller；The periphery of the cylindrical roller is provided with bearing outer ring；One end of the bearing inner race passes through outside dust-proof end cap and bearing
One end of circle is fixedly connected；The other end of the bearing inner race is fixedly connected by dust-proof end cap with the other end of bearing outer ring.
Further, the cylindrical roller is designed to cylindrical type.
Further, the card slot being adapted with cylindrical roller is provided with the retainer.
Further, the both ends of the bearing outer ring are both provided with the first rib.
Further, the both ends of the bearing inner race are both provided with the second rib.
The technique effect and advantage of the present invention：The single row roller bearing, two lassos can use tight fit, axis
Holding body includes bearing outer ring and bearing inner race, and one end of bearing inner race is consolidated by one end of dust-proof end cap and bearing outer ring
The other end of fixed connection and bearing inner race is fixedly connected by dust-proof end cap with the other end of bearing outer ring so that bearing removal
Install convenient, by the way that cylindrical roller is designed to cylindrical type, and be both provided with the both ends of bearing outer ring the first rib and
The both ends of bearing inner race are both provided with the second rib so that the contact line between modified roller and raceway is to reducing stress concentration
Effect it is good.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1- bearing bodies；2- retainers；3- cylindrical rollers；4- bearing outer rings；The first ribs of 5-；The second ribs of 6-；
7- bearing inner races；The dust-proof end caps of 8-.
Embodiment
