Abstract
The invention discloses a kind of single row roller bearings, and 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 on 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
It makes early on the books.From archaeology historical relic in terms of data, the most ancient bearing with modern times rolling bearing structure blank of China goes out
Now in modern Shanxi Province's Yongji County Xue Jiaya villages of B.C. 221~207 years (Qin Dynasty).After founding of New, this century is particularly
Since the seventies, under the powerful promotion of reform and opening-up, bearing industry enters a brand-new high-quality fast-developing period
At 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 on postal car
The patent of ball bearing.The H.R. hertz of 18 end of the centurys Germany delivers the paper on ball bearing contact stress.It is achieved in hertz
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 the axis of rolling
The design theory and Calculation of Fatigue Life held contribute.Then, the N.P. Dinko Petrov application newton law of viscosities of Russia
Calculate bearing friction.The O. Reynolds of Britain has carried out mathematical analysis to the discovery of Bristol, is derived Reynolds equation, is established from this
The basis of hydrldynamic pressure lubrication theory.It is 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 on 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, it is provided with the card slot being adapted with cylindrical roller on 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 at 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.
