Abstract
The utility model discloses a harmonic speed reducer ware bearing outer ring for robot, including the outer loop body, offer the V type groove that is used for installing the roller on the inner circle face of outer loop body, seted up a plurality of holding holes along the circumferencial direction on the outer loop body, inner and the V type groove in holding hole communicate, and the outer end is located the outer lane face of outer loop body, the downthehole heat conductivity colloidal silica that all is provided with of every holding. The utility model discloses harmonic speed reducer ware bearing outer ring for robot has advantages such as the radiating effect is good, long service life.
Description
Technical field
The utility model relates to technical field of bearings, is specifically a kind of robot harmonic speed reducer outer race.
Background technique
Need in industrial robot to use a large amount of bearings, its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of parts in transmission process.But because rotary bearing inside fast, repeatedly can produce a large amount of heats, the friction particularly between outer race and roller, heat yield is particularly serious, if poor radiation, bearing is very easy to damage.At present, usually take the mode offering radiation hole on outer race to dispel the heat, but this kind of radiating mode radiating effect is not satisfactory.
In order to solve the problems of the technologies described above, this case is life therefrom.
Summary of the invention
The purpose of this utility model is: the robot harmonic speed reducer outer race providing a kind of good heat dissipation effect, long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of robot harmonic speed reducer outer race, comprise outer shroud body, the inner ring face of outer shroud body offers the V-type groove for installing roller, described outer shroud body circumferentially offers some receiving holes, the inner of receiving hole is communicated with V-type groove, outer end is positioned on the face, outer ring of outer shroud body, is provided with thermal conductivity colloidal silica in each receiving hole.
Further, the inner of described thermal conductivity colloidal silica is the v-shaped structure matched with V-type groove, and the end face of outer end is lower than the aperture of place receiving hole.
Further, described receiving hole is the structure increased gradually outward from the inner, and thermal conductivity colloidal silica is the structure increased gradually outward from the inner matched with receiving hole.
Further, described receiving hole is uniformly distributed along the circumferencial direction of outer shroud body.
The utility model compared with prior art, have the following advantages: the utility model robot harmonic speed reducer outer race, the heat that outer shroud body and roller frictional produce outwards transmits by thermal conductivity colloidal silica, thus realize heat to shift from Bearing inner to Bearing outer rapidly, thoroughly, and dissipate eventually through air, thus guarantee whole bearing good heat dissipation effect, long service life.
Accompanying drawing explanation
Tu1Shi the utility model robot sectional view of harmonic speed reducer outer race.
In Fig. 2 Fig. 1, A-A is to sectional view.
Shown in figure: 1, outer shroud body 2, V-type groove 3, receiving hole 4, thermal conductivity colloidal silica.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of robot harmonic speed reducer outer race, comprises outer shroud body 1, the inner ring face of outer shroud body 1 offers the V-type groove for installing roller.Outer shroud body 1 circumferentially offers some receiving holes 3, the inner of receiving hole 3 is communicated with V-type groove 2, and outer end is positioned on the face, outer ring of outer shroud body 1.Thermal conductivity colloidal silica 4 is provided with in each receiving hole 3.
In the present embodiment, the inner of thermal conductivity colloidal silica 4 is the v-shaped structure matched with V-type groove 2, and the end face of outer end is lower than the aperture of place receiving hole 3.Design like this, has certain interval between thermal conductivity colloidal silica 4 and the inwall of bearing mounting hole, is beneficial to heat and is dispersed in air, can further improve the heat dispersion of bearing.The inner of thermal conductivity colloidal silica 4 is designed to V-structure simultaneously, makes it to match with V-type groove 2, so can not have any impact to the activity of roller in groove, guarantee that bearing working is stable, reliable.
In the present embodiment, described receiving hole is the structure increased gradually outward from the inner, and thermal conductivity colloidal silica is the structure increased gradually outward from the inner matched with receiving hole.Design like this, heat, by the trend from inside to outside spread gradually, can improve radiating efficiency to a certain extent, and then improves the radiating effect of whole bearing.
In order to improve radiating effect further, in the present embodiment, receiving hole 3 is uniformly distributed along the circumferencial direction of outer shroud body 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 robot harmonic speed reducer outer race, the heat that outer shroud body 1 and roller frictional produce outwards transmits by thermal conductivity colloidal silica 4, thus realize heat to shift from Bearing inner to Bearing outer rapidly, thoroughly, and dissipate eventually through air, thus guarantee whole bearing good heat dissipation effect, long service life.
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.
Claims (4)
1. a robot harmonic speed reducer outer race, comprise outer shroud body, the inner ring face of outer shroud body offers the V-type groove for installing roller, it is characterized in that: described outer shroud body circumferentially offers some receiving holes, the inner of receiving hole is communicated with V-type groove, outer end is positioned on the face, outer ring of outer shroud body, is provided with thermal conductivity colloidal silica in each receiving hole.
