Abstract
The utility model discloses a kind of retainer, support body including tubular, the most uniform on the periphery of support body offer some cylindrical pocket holes, the central axis in pocket hole and the central axis of support body are 45 ° of angles, and the central axis in adjacent pocket hole is mutually perpendicular to, the periphery between adjacent pocket hole is provided with projection.The invention also discloses a kind of crossed cylindrical roller bearing, this bearing is by increasing above-mentioned retainer between roller, and in adjusting roller movement state and increasing raceway, lubricating oil storage area is to improve the high-speed motion performance of crossed roller bearing.
Description
Technical field
This utility model belongs to crossed roller bearing, particularly relates to a kind of retainer and has its crossed roller bearing.
Background technology
Crossed roller bearing is to be existed by outer ring, an inner ring with 90 ° of V-type rolling channels and a group with 90 ° of V-type rolling channels
A kind of special construction types of bearings of the roller composition of square crossing arrangement in two V-type rolling channels, can increase between adjacent rollers
Add spacing block interval, it is also possible to be not added with spacing block (roller is in full dress state)；It is mainly used in the revolution of numerical control machining center
Workbench, industrial robot joint position or rotation portion, accurate measurement test equipment etc., under the conditions of general use, its
Running accuracy is higher, and bearing capacity is relatively strong, and axis rigidity is preferable；But this bearing due to when roller moves in raceway roller and
Between spacing block or roller and roller, mutually collision and roller displacement guided bone are bad, and bearing operates in fair speed
Time will produce vibration or slide, send noise even raceway spot temperature and steeply rise, therefore this bearing is general only exists
Operating under low-speed conditions, but be as machinery and add the development and progress of technology, existing market is in the urgent need to a kind of higher rotation speed
Crossed roller bearing occurs.
Summary of the invention
In order to solve the problem that existing crossed roller bearing exists, the purpose of this utility model be to provide a kind of retainer and
There is its crossed roller bearing, by increasing retainer between roller, profit in adjusting roller movement state and increasing raceway
Lubricating oil storage area improves the high-speed motion performance of crossed roller bearing.
In order to realize foregoing invention purpose, the technical scheme that this utility model employing is as described below:
A kind of retainer, including the support body of tubular, the most uniform on the periphery of support body offers some circles
Cylindricality pocket hole, the central axis in pocket hole and the central axis of support body are 45 ° of angles, and the central axis in adjacent pocket hole is the most vertical
Directly, the periphery between adjacent pocket hole is provided with projection.
A kind of crossed roller bearing, including inner ring, outer ring and roller, also includes above-mentioned retainer, and described roller is corresponding
In the pocket hole being installed on retainer.
Further, described inner ring is split-type structural or integral structure.
Further, described outer ring is split-type structural or integral structure.
Owing to using technique scheme, this utility model has a following superiority:
1, the roller in conventional cross roller bearing be full complement or with some independent spacing blocks by between roller
Separate, and crossed cylindrical roller bearing of the present utility model is by using the retainer of monolithic construction uniformly to be isolated by roller
Opening so that roller movement smooth sequential, make loading ability of bearing evenly, moment of friction change fluctuation reduces, beneficially bearing rotary
Precision steady in a long-term.
2, guidance quality when retainer of the present utility model adds roller movement, roller will not produce in motor process
The movement tendency toppled over and slide, is conducive to improving the rotating speed of bearing.
3, the space storing lubricating oil in the raceway of crossed roller bearing of the present utility model is strengthened, and advantageously reduces bearing
In motor process, heat produces and distributes, and can be greatly improved the motion rotating speed of bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model crossed roller bearing；
Fig. 2 is the perspective view of this utility model retainer；
In figure: 1, outer ring；2, inner ring；3, roller；4, support body；5, protruding；6, pocket hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described in further detail by embodiment.
As in figure 2 it is shown, a kind of retainer, including the support body 4 of tubular, the most uniform on the periphery of support body 4
Offering some cylindrical pocket holes 6, the central axis in pocket hole 6 is 45 ° of angles with the central axis of support body 4, and adjacent pocket hole 6
Central axis be mutually perpendicular to, the periphery between adjacent pocket hole 6 is provided with protruding 5.
As it is shown in figure 1, a kind of crossed roller bearing, including inner ring 2, outer ring 1 and roller 3, also include above-mentioned retainer,
In the pocket hole 6 that described roller 3 correspondence is installed on retainer.
Accordingly, the profile of the projection 5 on retainer 6 is suitable with the shape of the raceway on inside and outside circle.
Described inner ring 2 is integral type structure or is to be connected, by two halves inner ring, the split-type structural formed, and described outer ring 1 is
Integral structure or for being connected, by two semi outer rings, the split-type structural that forms.
It should be noted that split type two halves inner ring or two semi outer rings are all by screw, rivet or retaining ring
Connect composition integral inner ring or outer ring.
Crossed roller bearing of the present utility model is compared with traditional crossed roller bearing:
1, crossed roller bearing of the present utility model have employed all-in-one-piece retainer, is uniformly kept apart by roller, roller
Stable movement is orderly；And traditional crossed roller bearing includes that two kinds of structures, one are to arrange spacing block in raceway to use
In being kept apart by roller, another kind is the structure (i.e. roller is full dress) being not added with spacing block, and this will be because of spacing block and roller
Being all mutually contradictory motion unit and cause between roller and spacing block inconsistent in movement time gap, roller movement state is not
Unanimously, can mutual extrusion and collision, it is also possible to simple sliding.
2, conventional cross roller bearing uneven makes bearing load carrying capacity uneven because roller is arranged in raceway, causes axle
Holding change in friction force in operation process uneven, affect stablizing of bearing rotation precision, this utility model is by using monoblock type
Retainer structure makes loading ability of bearing evenly, and moment of friction change fluctuation reduces, and beneficially bearing rotation precision is steady in a long-term.
3, conventional cross roller bearing because of spacing block less than normal and separate, the motion guided bone effect to roller is inconspicuous
And cause roller to have the movement tendency toppling over and doing simple sliding in motor process；Retainer of the present utility model is by pocket hole on it
Design and the protruding design of structure substantially increase roller movement guidance quality, roller will not produce in motor process topple over and
The movement tendency of simple sliding, is conducive to improving the rotating speed of bearing.
4, there is spacing block between conventional cross roller bearing adjacent rollers or there is no spacing block (roller is in full dress shape
State), in raceway, the memory space of grease is less；Keeper of the present utility model is only provided with projection on periphery, is protecting
Do not design projection on the inner headed face of holder, therefore there are on circular direction in keeper between adjacent rollers and cut off the sky opened
Between, the space storing lubricating oil in such raceway is strengthened, and during advantageously reducing bearing movable, heat produces and distributes, permissible
It is greatly improved the motion rotating speed of bearing.
