On circle, each oiling channel is made of two subchannels, two subchannel outer ends on each oiling channel with an oil filler point
Connection, inner end connect respectively with corresponding retainer.
Preferably, the oiling number of channels is at least four, and the quantity of oiling channel is even number.
Preferably, the subchannel described in every is made of sequentially connected oil injecting part, transition part and oil storage department, it is described
Transition part connection oil injecting part and oil storage department, the oil injecting part connected with corresponding oil filler point, oil storage department and corresponding holding
Frame connects.
Preferably, it is both provided with angle between the transition part and oil injecting part and oil storage department.
Preferably, it is provided with cap stopper in the oil filler point.
Preferably, the cap stopper is interference fitted with oil filler point, and the cap stopper uses epoxy resin cap stopper or rubber
Capsule plug, through offering through-hole on the cap stopper.
Preferably, the quantity of the inner ring is two, circular cone of each inner ring by a row retainer and thereon
Roller is connected with the rolling face on outer ring, the inner ring coaxial arrangement described in two, and sets a spacer ring between two inner rings, often
Rib is both provided on the outer end outer diameter of a inner ring.
Beneficial effects of the present invention：Compared with prior art, a kind of high speed high lubrication double row tapered roller provided by the invention
Sub- bearing, it is rational in infrastructure, set inside outer ring both can with oiling can also oil storage oiling channel, and on oiling channel be closed have
Cap stopper with through-hole forms the chamber almost closed between outer ring, taper roller and inner ring, when bearing is when running at high speed,
Bearing oil is always in the chamber of bearing, and cap stopper can prevent bearing oil from overflowing, and substantially improve and keep double-row conical axis

Each column retainer 2 is equipped with a number of taper roller 3, and a number of oiling channel 5 is provided on the outer ring 1.
Wherein, a number of oiling channel 5 uniform circular row of line centered on the central shaft of outer ring 1 is arranged on outer ring
On 1, each oiling channel 5 is made of two subchannels, two subchannel outer ends on each oiling channel 5 with an oil filler point
9 connections, inner end connects respectively with corresponding retainer 2.
In embodiments of the present invention, 5 quantity of oiling channel is at least four, and the quantity of oiling channel 5 is even
It is several.
Further, the subchannel described in every is made of sequentially connected oil injecting part 6, transition part 7 and oil storage department 8,
The transition part 7 connects oil injecting part 6 and oil storage department 8, the oil injecting part 6 are connected with corresponding oil filler point 9, oil storage department 8 and
Corresponding retainer 2 connects, and angle is both provided between the transition part 7 and oil injecting part 6 and oil storage department 8.When needing oiling
When, by the oil injecting part 6 of bearing oil injection channel 5, bearing oil enters oil storage department after flowing through the transition part 7 connected with oil injecting part 6
8, angle is both provided between transition part 7 and oil injecting part 6 and oil storage department 8, effectively bearing oil can be stored in oil storage department 8,
It prevents outside bearing oil reflux outflow outer ring 1, ensures the high lubricating effect inside double-row conical bearing, bearing oil is through oil storage department
It is flowed on retainer 2 after 8, bearing oil comes into full contact with taper roller 3, retainer 2,1 inner wall of outer ring, 4 outer wall of inner ring, especially
Ensure the content of bearing oil between 1 inner wall of taper roller 3 and outer ring, 4 outer wall of inner ring, greatly reduce frictional force, reduce biserial
Friction level during taper roll bearing high-speed rotation.
Further, cap stopper 10 is provided in the oil filler point 9, the cap stopper 10 is interference fitted with oil filler point 9, and
The cap stopper 10 uses epoxy resin cap stopper or rubber cap stopper, runs through on the cap stopper 10 and offers through-hole.Due to cap stopper
It is made of epoxy resin or rubber, epoxy resin and rubber are respectively provided with very good adhesion, elasticity and stabilization chemically
Can, the adhesiving effect made of epoxy resin or rubber between cap stopper 10 and oil filler point 9 is good, is not easy the centrifugal action by bearing
And it is thrown out of.The outer wall of cap stopper 10 is fitted tightly on the inner wall of oil filler point 9, i.e., cap stopper 10 is just swollen after being knocked in oil filler point 9
It is swollen, reach cap stopper 10 and oil filler point 9 is interference fitted.
Further, the quantity of the inner ring 4 is two, and each inner ring 4 is by a row retainer 2 and thereon
