Description
Technical field
The present invention relates to a kind of oil-well rig turntable self-contained bearing, and in particular to a kind of suitable for 15000m ultradeep well oil
Rotary table for drilling machine base bearing.
Background technology
Existing main bearing of rotary has using two sets of single-row angular contact thrust ball bearing pairing uses；Also have using a set of two-way
Angular contact thrust ball bearing.But bearing outside diameter size is maximum at present is less than 1700mm, and specified Dynamic And Static Loads can not meet
15000m ultradeep well oil-well rig turntable loading demands.Also there are not 15000m ultradeep well oil-well rig turntable base bearings both at home and abroad
The report of relative dimensions.
Content of the invention
The purpose of the present invention is that open one kind can meet 15000m ultradeep well stones in order to overcome shortcoming present in prior art
Oily Rotary table for drilling machine base bearing, its overall dimensions are minimum, and mechanical dimensions are also minimum.
When oil drilling disk operation principle is that drilling tool drilling well works, there is the axial heavy load lotus in direction down；When drilling tool is moved back
When going out, there is the axial load that opposite direction is lighter.Meet 15000m oil drilling load from rotary table requirements, bearing there must be two row,
Above-listed bear heavy duty axial force downwards, following bear lighter opposite direction axial force.The present invention adopts biserial thrust angular contact ball axle
Hold, two row balls share seat ring, main frame axial dimension can be reduced, save axially mounted space.
The technical scheme is that：
Ultradeep well oil-well rig turntable base bearing, keeps including the first blowout patche, the first retainer, the first steel ball, seat ring, second
Frame, the second steel ball, the second blowout patche, the pocket hole of first retainer is ellipse, is in the semicircle by two same diameters
Between press from both sides what rectangle was constituted；The second retainer pocket hole is that circle, first steel ball size are more than the second steel ball size,
The first retainer pocket centerline hole is 15 ° with bearing centre of gyration wire clamp angle beta.
The seat ring external diameter is 1950mm.
The first blowout patche external diameter 1858mm, internal diameter 1680mm.
The second blowout patche external diameter 1820mm, internal diameter 1676mm.
The second retainer pocket centerline hole is parallel with bearing centre of gyration line.
First retainer pocket hole, half diameter of a circle 0.6mm bigger than the first steel ball size.
First steel ball size is 79.375-85.725mm.
Second steel ball size is 55-60.325mm.
On the contact surface of the seat ring and both retainers, on seat ring contact surface or retainer contact surface, open up circular arc
Groove or square groove.
Because bearing is acted on by bidirectional propulsion load, when drilling tool works, big ball is not stressed by heavily loaded axial force, bead；Work as brill
When tool is exited, big ball does not stress, and bead receives opposite direction underload.When cutter is exited, stress or rotating speed are all relatively low, and second
Circular design is pressed in retainer pocket hole, and the second retainer pocket centerline hole is parallel with bearing centre of gyration line.
First retainer pocket centerline hole is 15 ° with bearing centre of gyration wire clamp angle beta.First retainer pocket centerline hole with
Bearing centre of gyration wire clamp angle is according to the first steel ball rotation and revolution speed, determines according to velocity synthesis.
The ultradeep well oil-well rig turntable base bearing of the present invention, the first steel ball and the second steel ball share a seat ring, axle
Hold overall dimensions largest outside diameter 1950mm.Single-row bearing is highly about 170mm, and the present invention adopts biserial thrust angular contact ball axle
Hold, two row balls share seat ring, assembling height only 273mm, reached meet the load of 15000m ultradeep well oil-well rig turntables will
Ask, while bearing overall dimensions are minimum.
The first retainer pocket hole design ovalisation of the present invention, half diameter of a circle of the first retainer pocket hole compare steel ball size
Big 0.6mm, the contact area closer to steel ball size, such ball and pocket internal surface of hole increase, so as to reduce the contact of pocket hole
Stress and abrasion, also reduce pocket hole radial clearance excessive and produce retainer swing；Oval pocket hole can enable lubricating oil a large amount of
Pass through, so that bearing and retainer are winding is effectively cooled, effectively reduce bearing noise.Retainer and both raceway contacts faces it
One opens up arc groove or square groove, and this set one is to reduce the contact area with seat ring end face, and two is that the oil for splashing has
It is stored in lubricating contact face in groove a little, reduces friction, reduces the purpose of noise.
