Abstract

A kind of double half inner ring, double semi outer rings crossed roller bearings disclosed by the utility model, including outer ring（1）, inner ring（2）, roller（3）And raceway（4）, the outer ring（1）And inner ring（2）Be two half-turns, i.e., double half inner rings and double semi outer rings, the raceway（4）Between double half inner rings and double semi outer rings.The utility model by the inside and outside circle of bearing by being designed as double half inner rings and double semi outer rings structure, in use if raceway or roller appearance abrasion cause bearing accuracy to fail, bearing can be made to restore precision again by carrying out Repair gene, extend bearing service life.It is also connected without clamp spring due to not being bolted between double half inner rings, between double semi outer rings, it is possible to increase the diameter of rolling element to greatest extent in a certain range to increase the load capacity of bearing so that it can bear the load of bigger.

Description

A kind of crossed roller bearing of pair of half inner ring, double semi outer rings

Technical field

The utility model belongs to crossed roller bearing technical field, is primarily related to a kind of double half inner ring, double semi outer rings Crossed roller bearing.

Background technology

Crossed roller bearing is a kind of special type bearing.Since crossed roller bearing inner ring or outer ring are to be divided into two The construction of half-turn even if being applied in preloading, can also carry out high-precision rotation so bearing clearance can adjust.However Most of in present bearing products is expendable consumed product, and raceway is ground after transporting row by prolonged rotation Damage, the failure of rollers wear precision, the bearing that then will more renew, this undoubtedly for will greatly waste, it is at the same time existing Bearing there is also a larger drawbacks, the in general diameter of the rolling element of the load capacity of bearing and bearing itself There is relationship, the load capacity of bearing can be increased to a certain extent by increasing the diameter of rolling element, however present bearing, especially It is that crossed roller bearing is limited by size itself, used rolling element diameter is all less than normal on the basis of processing method now Without excavating the load-bearing capacity of bearing itself to the greatest extent.

Utility model content

Thus the purpose of this utility model generates, propose the crossed roller bearing of a kind of pair of half inner ring, double semi outer rings, reach The utilization rate and load capacity for improving bearing extend the service life of bearing and restore the purpose of bearing accuracy.

To achieve the goals above, the technical scheme adopted by the utility model is that：A kind of pair of half inner ring, double semi outer rings intersect Roller bearing, including outer ring, inner ring, roller and raceway, the raceway be located at it is double between half inner ring and double semi outer rings, it is described Roller is mounted in raceway, and the outer ring and inner ring are two half-turns, i.e., double half inner rings and double semi outer rings.

Roller described in the utility model is mounted on by way of cross arrangement on raceway.

The utility model is using process by the way that the inside and outside circle of bearing is designed as double half inner rings and double semi outer rings structure In when raceway either roller occur abrasion cause bearing accuracy fail if can be in double half inner rings or double semi outer rings phase The side being engaged, which is processed whole circle or individual pen, makes bearing restore precision again, extends bearing service life.By It is not bolted between double half inner rings, between double semi outer rings and is connected without clamp spring yet, it is possible in a certain range most The diameter of the increase rolling element of limits is to increase the load capacity of bearing so that it can bear the load of bigger.

Description of the drawings

Fig. 1 is the assembling structure schematic diagram of the utility model.

In figure：1, outer ring, 2, inner ring, 3, roller, 4, raceway.

Specific implementation mode

Below in conjunction with the accompanying drawings, by specific implementation mode, the present invention will be further described；

As shown in Figure 1, one kind double half inner ring, double semi outer rings crossed roller bearings described in the present embodiment, including outer ring 1, Inner ring 2, roller 3 and raceway 4, wherein outer ring 1 and inner ring 2 are two half-turns, i.e., double half inner rings and double semi outer rings, described double The raceway 4 rolled for roller 3 is provided between half inner ring and double semi outer rings, the processing to raceway 4 is by distinguishing double half-turns It is processed, raceway is cooperatively formed by double half-turns after machining, the roller 3 is installed by way of cross arrangement On raceway 4, roller 3 is standard fitting.

When assembly, first by the monolithic inner ring in double half-turns, monolithic outer ring matches then to assemble roller and complete, Then the other half Internal and external cycle is packed into again, that is, completes assembly.Since double half inner rings, double semi outer rings crossed roller bearing do not have There are connection holes, mounting hole, there was only the processing of raceway inside, in the processing of outer ring, reduce connection holes, the interference of mounting hole is asked Topic makes to have between the Internal and external cycle of bearing as well as the utility model technique itself, the particularity of structure larger Interval, this, which is also meaned that, is carrying out the diameter of roller 3 being arranged some larger when roller is selected in assembly, works as rolling Bearing when being relatively large in diameter of son can increase the bearing capacity of bearing to the full extent.

In the bearing series products of general type, using bearing for a long time, raceway 4 or roller 3 must later Abrasion will be will appear and lead to bearing accuracy reduction or precision failure, just needed replacing when there is such case new Bearing, however this practicality bearing then directly double half-turns can be matched contact end face be processed amendment can just make Bearing restores precision again, extends bearing service life.
