Description
Technical field
The present invention relates to the turntable bearing for industrial robot, and it belongs to mechanical field.
Background technology
Industrial robot, will be to non-next life as the support technology of advanced manufacturing industry and the new industry of informationized society
Production and social development play more and more important effect.Industry of industrial robots has been included in 13 planning by China, hair
Exhibition industrial robot has great strategic importance, and it is that the national manufacturing industry of measurement one is horizontal important with scientific and technological level
Mark, and the important tool and means of remodeling China's manufacturing industry competitive advantage, are more to speed up the business of China's industrial repositioning upgrading
The choosing of reality.
But the critical component of current China industrial robot still relies on import, especially robot bottom turntable shaft
Hold.The bearing at this position is very high to bounce precision prescribed, and needs reciprocating rotary, vertical sometimes according to working condition requirement, bearing
Installation.For common turntable bearing, circumference total backlash after assembling it is difficult to ensure that, this usual total backlash can be very big.If bearing
Vertical installation, gap can largely be accumulated at top, not only bad for the steady operating of rolling element and spacing block, when serious, every
It can be conjugated from block, cause the damage that bearing is too early.
Therefore, high-accuracy industrial robot turntable bearing is researched and developed, there is weight to the long term growth for promoting Robot industry
Want meaning.
The content of the invention
In view of the defects of existing production method is present, the present invention is provided to the turntable bearing of industrial robot, in structure
In design, increase adjustment spacing block, adjustment spacing block can farthest reduce the total backlash of circumferencial direction, avoid rotating disk
Bearing Traditional control rolling element diameter, spacing block precision, raceway diameter, greatly save cost.
To achieve the above object, the technical solution adopted in the present invention is for turning described in the turntable bearing of industrial robot
Dish axle, which is contracted, includes the first seat ring, bolt, the second seat ring, blowout patche, sealing ring, nut, roller and split spacing block；Seat ring and blowout patche
Between sealing ring is set, the first seat ring is fixed with the second seat ring by bolts and nuts, and raceway is provided between seat ring and blowout patche,
Have in raceway and several split spacing blocks and several rollers are set, a split spacing block is set between each two roller, point
The intermediate beam variable-width on two roller centre point line directions of body spacing block.
The roller is cylinder, and the center line of two neighboring cylinder roller is in 90 degree, and cylinder roller intersects successively
It is arranged on raceway.
The split spacing block is two classes, and one kind is conventional spacing block, and another kind of is spacing block of the intermediate beam than routine
The big adjustment spacing block of size.
The size range of the adjustment spacing block is bigger 1 ± 0.2mm than the intermediate beam of the spacing block of routine.
The size range of the adjustment spacing block chooses the value according to split spacing block circumferencial direction total backlash.
First by conventional spacing block normal mounting in raceway, with the value of apparatus measures circumferencial direction total backlash, according to operating mode,
Conventional spacing block is replaced with adjustment spacing block again, until circumferencial direction total backlash working condition requirement.
The rolling element is spherical.
After the above method, had the advantages that compared with art methods：
The turntable bearing precision of the present invention is high, speed is high, applied to high-accuracy industrial robot turntable, high-precision machine tool
The mechanical significant points such as turntable and high-speed tire forming machine rocking arm, use, work well through installation.
Brief description of the drawings
Fig. 1 is the turntable bearing Local map with adjustment spacing block；
Fig. 2 is conventional spacing block；
Fig. 3 is adjustment spacing block.
Wherein：1st, the first seat ring, 2, bolt, 3 split spacing blocks, 4, roller, 5, blowout patche, 6 second seat rings, 7, sealing ring,
8th, nut, 9, conventional spacing block, 10, adjustment spacing block.
Specific embodiment
Existing cylinder rolling element is 100, then split spacing block is also 100.Split spacing block is divided to a, b two kinds, during a is
Between the less conventional spacing block of beam, b is the larger adjustment spacing block of intermediate beam.When design adjusts spacing block, b types intermediate beam one
As it is bigger 1mm than a type intermediate beams or so, mainly or the operating mode depending on product, precision etc., 1mm or so is accuracy height to this value,
The best numerical value of universality, when needing smaller circumferencial direction total backlash, b is more smaller than the increment of a intermediate beam, and increment is small
Shi Jingdu is bigger.φ Dw are roller diameter.
Set-up procedure：
First with 100 rolling elements and 100 a type spacing block normal mountings in raceway.It is total with apparatus measures circumferencial direction
The value in gap, compare the requirement of drawing.A type spacing blocks are replaced with b types adjustment spacing block again, until circumferencial direction total backlash meets
Drawing requirement.The specific method for choosing b types adjustment spacing block, if it is 0.6mm with the value of apparatus measures circumferencial direction total backlash,
, can be with the adjustment spacing block of design and installation 0.5mm specifications when working condition requires higher.
