To load, axial load and tilting moment, therefore in the joint part of industrial robot, the rotary table of machining center, machine
It is widely used in the rotation portion of tool hand, fine measuring instrument.
Conventional thin-walled crossed roller bearing is generally mostly seperated circle, and generally outer ring is seperated, with rivet or screw two
A seperated circle connects, because of outer ring separate structure, the precision after outer ring machining accuracy and assembly is limited, and host is not achieved
Running accuracy requirement only can be suitably used for internally enclosing the occasion for having running accuracy to require, with thin-walled crossed roller bearing application model
The expansion enclosed, in the operating condition occasion for much needing the requirement of outer ring running accuracy, traditional thin-walled crossed roller bearing is obviously not
It is able to satisfy above-mentioned application requirement.
Summary of the invention
In order to solve the problems in background technique, the utility model proposes a kind of thin-wall crossed cylindrical roller bearings, in axis
Bearing outer-ring sets axial joint-cutting and guarantees that the globality of outer ring to guarantee the running accuracy of outer ring can be applied to that outer ring is required to rotate
The workplace of precision.
In order to realize above-mentioned purpose of utility model, the utility model uses technical solution as described below:
A kind of thin-walled crossed roller bearing, including outer ring, inner ring, cylindrical roller and spacing block, outer ring inner headed face and
Respectively corresponded on the periphery of inner ring equipped with the two orthogonal raceways of column, two column raceways on outer ring with cycle surface angle
In 45 °, two column raceways on inner ring are in 45 ° with inner ring end face angle, are equipped between outer ring and the raceway of inner ring several
Cylindrical roller, two adjacent cylindrical roller right-angled intersections are arranged and are separated with spacing block；Outer ring, inner ring are annular shape,
Along a joint-cutting is axially arranged on the periphery of outer ring, joint-cutting extends radially through the inner headed face of outer ring, and joint-cutting axially penetrates through outer ring
Upper and lower end faces, the arranged on left and right sides on cycle surface positioned at joint-cutting are respectively equipped with fabrication hole.
A kind of thin-walled crossed roller bearing, is respectively equipped with external annular groove on the inside of the upper and lower end face of outer ring,
It is respectively equipped with inner ring connected in star on the outside of inner ring upper and lower end face, corresponding inner and outer rings connected in star forms seal groove, in seal groove
It is provided with sealing element.
A kind of thin-walled crossed roller bearing, uniform intervals are equipped with several oil filler points, note on the periphery of outer ring
Oilhole is connected to raceway.
Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
1, joint-cutting is set on the utility model bearing outer ring, is easily installed the cylindrical roller of bearing, installs cylindrical roller
Outer ring closes up naturally afterwards, and outer ring is overall structure, and outer ring axial dimension is big, the thin-walled crossed roller bearing of relatively common specification,
The outer ring processing of the utility model is relatively easy, and the precision after capable of guaranteeing outer ring machining accuracy and assembly in processing is sufficiently protected
The running accuracy of outer ring is demonstrate,proved；In addition, assembly cylindrical roller after substantially assembly process completed, relatively common specification it is thin
The assembly of wall crossed roller bearing, the utility model simplify process, save time and human cost.
2, compared with traditional thin-walled crossed roller bearing, the rigidity of the utility model is improved, and is remained single
Bearing is able to bear the characteristics of radial load, axial load and tipping load.

Specific embodiment
By the following examples can detailed explanation the utility model, open the purpose of this utility model is intended to protect
All technological improvements in the scope of the utility model.
A kind of thin-walled crossed roller bearing in conjunction with described in attached drawing 1-2, including outer ring 1, inner ring 5, cylindrical roller 2 and isolation
Block 3 is respectively corresponded on the inner headed face of outer ring 1 and the periphery of inner ring 5 equipped with the two orthogonal raceways of column, on outer ring 1
Two column raceways are in 45 ° with 1 end face angle of outer ring, and two column raceways on inner ring 5 are in 45 ° with 5 end face angle of inner ring, in outer ring
It is equipped with several cylindrical rollers 2 between 1 and the raceway of inner ring 5, adjacent two 2 right-angled intersections of cylindrical roller setting and with being isolated
Block 3 separates, and outer ring 1, inner ring 5 are annular shape, and along a joint-cutting 6 is axially arranged on the periphery of outer ring 1, joint-cutting 6 is radial
