Abstract
The invention discloses a double-row cylindrical roller bearing with an oil hole, which comprises an outer ring (1), an inner ring (2), rollers (3), and a seal ring (4). Double-row cylindrical rollers (3) are arranged between the outer ring (1) and the inner ring (2); the inner ring (2) is toroidal, two parallel roller rollways are arranged on the outside of the inner ring (2), one side of one of the roller rollway is provided with a trough; the inner ring (2) is provided with two parallel oil holes (5) along the radial direction, and the inner hole of the inner ring (2) leads to the two parallel roller rollways. Compared with the prior art, the invention greatly reduces friction, friction heating and energy loss, and improves lubrication condition, lubrication quality and bearing service life.
Description
Technical field
The present invention relates to a kind of band oil hole Biserial cylindrical roller bearing, belong to the roller bearing technical field of usheing to seat.
Background technique
Rolling bearing units are owing to have advantages such as compact structure, perfect, the easy to loading and unloading and self-aligning amplitude of sealing are bigger, make the frame of many main frames can adopt into the technology of structural section punching out or welding, have also improved the performance of machine.Its characteristics are: because the outer ring is that sphere cooperates with bearing support, when bearing support or its reference for installation and desired center had skew, the energy self-aligning so can be used for the place of flexible major axis or installation basic roughness, can bear bigger axial load.
The roller bearing of usheing to seat is made up of outer cylinder bearing and cylindrical axes bearing two-part, its working principle and other deep groove ball bearing are basic identical, but the outer ring of this bearing is sphere with bearing support to be contacted, and has formed active state freely, makes bearing can realize the self-aligning function.
Summary of the invention
A kind of band oil hole Biserial cylindrical roller bearing of the present invention comprises outer ring, inner ring, cylindrical roller, seal ring; Two line column rollers are arranged between described outer ring and the inner ring; Inner ring radially has two parallel oil holes, leads to two roller raceways arranged side by side by the endoporus of inner ring; Oil hole is tapped through hole, the thin through hole in close inner ring roller raceway place near inner ring endoporus place, and the diameter of tapped through hole is greater than the diameter of thin through hole.The external diameter of described outer ring is the ladder platform, and last ladder surface is a gear; Two roller raceway grooves are arranged in the endoporus of outer ring, in each roller raceway groove an arc groove is arranged; Roller raceway groove one side of outer ring endoporus has a rectangular recess; The fillet of leaning now to one side, then to the other of outer ring endoporus; The outer ring has equally distributed tapped through hole vertically; Two roller raceway grooves are arranged in the described inner ring external diameter, in each roller raceway groove an arc groove is arranged; Roller raceway groove one side of inner ring external diameter has a rectangular recess; The fillet of leaning now to one side, then to the other of inner ring external diameter; The fillet of leaning now to one side, then to the other of inner ring endoporus; Inner ring is uniform-distribution with tapped through hole vertically.
The present invention compared with prior art, because the outer ring is external gear, it can be directly and other gear or tooth bar constitute gear driving pair, bearing can directly be fixed on the link by outer ring through hole and inner ring tapped through hole, thus the present invention has improved the working efficiency and the life-span of bearing greatly; Significantly reduce friction, improved lubricating condition, improved lubricated quality, reduced frictional heating and energy loss, thereby improved bearing life greatly.
