Further, the thermal conductivity colloidal silica being positioned at the receiving hole on outer race is the v-shaped structure matched with V-type groove near one end of V-type groove, and the end face of the other end is lower than the aperture of place receiving hole.
Further, the thermal conductivity colloidal silica being positioned at the receiving hole on bearing inner ring is the v-shaped structure matched with V-type groove near one end of V-type groove, and the end face of the other end is lower than the aperture of place receiving hole.
Further, be positioned at the receiving hole on outer race, roller and be positioned at the receiving hole one_to_one corresponding setting on bearing inner ring.
Further, described receiving hole is uniformly distributed along the circumferencial direction of outer race or bearing inner ring.
Further, separator is provided with between adjacent two rollers.
Further, the two ends of described separator are the arcuate structure matched with adjacent rollers.
The utility model compared with prior art, has the following advantages:
One, the utility model harmonic speed reducer crossed roller bearing, the heat that outer race and roller frictional produce outwards transmits by the thermal conductivity colloidal silica be positioned on outer race, the heat that bearing inner ring and roller frictional produce outwards transmits by the thermal conductivity colloidal silica be positioned on bearing inner ring, thus realize heat to shift from Bearing inner to Bearing outer rapidly, thoroughly, and dissipate eventually through air, whole bearing good heat dissipation effect, long service life.
Two, the utility model harmonic speed reducer crossed roller bearing, by arranging separator between adjacent two rollers, effectively can prevent the phase mutual friction toppled between roller of roller, avoid end thereof contacts phenomenon or deadlock phenomenon that roller occurs, thus improve the stability of bearing working.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model harmonic speed reducer crossed roller bearing.
In Fig. 2 Fig. 1, A-A is to sectional view.
Shown in figure: 1, bearing inner ring 2, outer race 3, roller 4, roller groove 41, V-type groove 5, receiving hole 51, interior receiving hole 52, outer receiving hole 6, thermal conductivity colloidal silica 61, interior thermal conductivity colloidal silica 62, outer thermal conductivity colloidal silica 7, separator.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of harmonic speed reducer crossed roller 3 bearing, comprises bearing inner ring 1, outer race 2 and roller 3.The position that bearing inner ring 1 is relative with outer race 2 offers V-type groove 41, two V-type grooves 41 respectively and constitutes roller groove 4 for installing roller 3.Roller 3 intersecting vertical is distributed in roller groove 4.More than be prior art, primary object of the present utility model is: outer race 2 and bearing inner ring 1 circumferentially offer some receiving holes 5 respectively.The one end being positioned at the receiving hole 5 on outer race 2 is communicated with roller groove 4, and the other end is positioned on the face, outer ring of outer race 2.The one end being positioned at the receiving hole 5 on bearing inner ring 1 is communicated with roller groove 4, and the other end is positioned on the inner ring face of bearing inner ring 1.Thermal conductivity colloidal silica 6 is provided with in each receiving hole 5.Below remember that the receiving hole 5 be positioned on bearing inner ring 1 and thermal conductivity colloidal silica 6 are respectively receiving hole 51 and thermal conductivity colloidal silica 61, the receiving hole 5 that note is positioned on outer race 2 and thermal conductivity colloidal silica 6 are respectively outer receiving hole 52 and outer thermal conductivity colloidal silica 62.
In the present embodiment, outer thermal conductivity colloidal silica 62 is the v-shaped structure matched with V-type groove 41 near one end of V-type groove 41, and the end face of the other end is lower than the aperture of place receiving hole 5; Interior thermal conductivity colloidal silica 61 is the v-shaped structure matched with V-type groove 41 near one end of V-type groove 41, and the end face of the other end is lower than the aperture of place receiving hole 5.So, the inwall of outer thermal conductivity colloidal silica 62 and bearing mounting hole and have certain interval between interior thermal conductivity colloidal silica 61 and rotating shaft, is beneficial to heat and is dispersed in air, can further improve the heat dispersion of bearing.Thermal conductivity colloidal silica 6 is designed to V-structure near one end of V-type groove 41 simultaneously, makes it to match with V-type groove 41, so can not have any impact to the activity of roller in groove 3, guarantee that bearing working is stable, reliable.
Can both pass smoothly in order to ensure the fricative heat of each roller 3, further raising radiating effect, in the present embodiment, outer receiving hole 52, roller 3 and interior receiving hole 51 one_to_one corresponding are arranged, that is outer thermal conductivity colloidal silica 62, roller 3 and interior thermal conductivity colloidal silica 61 also one_to_one corresponding setting, meanwhile, receiving hole 5 is uniformly distributed along the circumferencial direction of outer race 2 or bearing inner ring 1.
Above-described thermal conductivity silica gel is a kind of existing material, and it is the dealcoholized type one-component RTV silicone rubber with conducting filler preparation, has splendid heat trnasfer, heat dispersion.
The utility model harmonic speed reducer crossed roller 3 bearing, outer race 2 and the fricative heat of roller 3 outwards transmit by outer thermal conductivity colloidal silica 62, bearing inner ring 1 and the fricative heat of roller 3 outwards transmit (direction namely towards bearing hole is transmitted) by interior thermal conductivity colloidal silica 6, thus realize heat to shift from Bearing inner to Bearing outer rapidly, thoroughly, and dissipate eventually through air, whole bearing good heat dissipation effect, long service life.
In addition, in the present embodiment, between adjacent two rollers 3, be provided with separator 7, and the two ends of separator 7 are the arcuate structure matched with adjacent rollers 3.By arranging separator 7 between adjacent two rollers 3, effectively can prevent the phase mutual friction toppled between roller 3 of roller 3, avoiding end thereof contacts phenomenon or deadlock phenomenon that roller 3 occurs, thus improving the stability of bearing working.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its scope protected according to right.
