Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face, which combines to be specifically illustrating, is expanded on further the utility model.
Reference picture 1, Fig. 2, the gear integration bearing of the external gear teeth, including interior annular 1, outer toroid and in being arranged on
Ball bearing mechanism 2 between annulus 1 and outer toroid, the gear teeth 3 are uniformly placed with along the axial direction of outer toroid on the outer wall of outer toroid, with
Outer toroid is as a gear；The outer surface of gear includes the contact surface that an actuator rotated with drive gear contacts, contact surface
On be stained with wearing layer 4 made of magnetic rubber, the inside of wearing layer 4 is provided with mesh grid 5 made of the braiding of basalt fibre line.
The utility model is by the way that gear and bearing are combined together, and using the outer toroid of bearing as gear, is easy to drive by actuator
Dynamic outer toroid rotates, and reduces gear and the intermediate link of outer toroid transmission.In addition, the utility model is by optimizing the gear teeth 3
The structure of contact surface, wearing layer reduces abrasion when metal driving part engages with metal teeth 3, in addition by magnetic rubber system
Into wearing layer, magnetic rubber has the effect of magnetic absorption for magnetic metal, and then improves engagement effect.The utility model
The anti-wear performance of wearing layer is improved by mesh grid 5, the reticulate body formed by being provided with basalt fibre braiding inside wearing layer,
It is easy to the stripping of wearing layer.
The thickness of wearing layer is 1mm~1.2mm, and the thickness of mesh grid is 0.2mm~0.4mm.The thickness of fluorescence coating is
0.08mm~0.1mm.
Basalt fibre line is the basalt fibre line that outer surface is coated with fluorescence coating 6 made of fluorescer.This practicality is new
For type by fluorescence coating, when wearing layer wears to a certain extent, fluorescence coating is exposed, is easy to remind user to change wearing layer.
It is directed to and how mesh grid is arranged on inside wearing layer, there can be following two schemes：
As a kind of preferred scheme, wearing layer includes one and is located at wearing layer positioned at outer layer of the wearing layer away from the side of the gear teeth 3, one
Internal layer close to the side of the gear teeth 3, between outer layer and internal layer, internal layer is connected with contact surface for mesh grid 5；Outer layer passes through by one
The adhesive layer of the mesh of mesh grid 5 and internal layer gluing.The utility model is easy to mesh grid 5 by optimizing the structure of wearing layer

Type is by having additional annular recess.The amount of storage of lubricating oil is added, in addition, interior annular 1 is in rotary course, due to centrifugal force
Lubricating oil in annular recess can be thrown away, and then be sprayed onto on ball bearing mechanism 2, improve the lubricant effect of ball bearing mechanism 2.Ring-type
The width of groove is 2mm~5mm, and depth is 8mm~9mm.Lubricating oil is in paste.The external diameter of sealing ring is more than the interior of outer toroid
Footpath, the internal diameter of sealing ring are more than the external diameter of interior annular.The inwall for being easy to implement sealing ring and outer toroid offsets, sealing ring and inner circle
There is gap between the inwall of ring.
Cavity 7 in being provided with one in outer toroid, middle cavity 7 is interior filled with liquid metal, and middle cavity 7 is annular in shape, in middle cavity 7
Central axis of the mandrel line parallel to outer toroid；/ 3rd of the volume of liquid metals no more than the volume of middle cavity 7, and not
Less than a quarter of the volume of middle cavity 7；It is further fixed on metallic rod 8 made of a titanium alloy in outer toroid, the one of metallic rod 8
In the insertion of end in cavity 7, cavity 7 flushes with the outer surface of outer toroid in the other end stretching of metallic rod 8.The utility model passes through
Cavity 7 in being provided with one in outer toroid, the weight of outer toroid is reduced, on the other hand, in the middle internal-filling liquid state metal of cavity 7, liquid gold
Category at high temperature (such as more than 40 degree), is liquid, has mobility.Using liquid metal in the presence of the temperature difference it is caused right
Stream, external annulus carries out heat conduction, so as to improve the thermal shock resistance of outer toroid.Also, because improving heat conductivility, keep away
Exempt from because uneven heating is even, the problem of causing deformation.Flow-disturbing effect in being realized by metallic rod in cavity 7, further improve
Thermal conductivity.In process of production, can be so that first, outer toroid and lower outer toroid are gone up in making respectively, and outer toroid is by upper outer toroid with
Split is formed above and below outer toroid.And when upper outer toroid and lower outer toroid make, in upper outer toroid and lower outer toroid
The through hole through metallic rod is offered at least one, metallic rod is welded on through hole, realizes the fixation of metallic rod.Upper outer toroid
With being provided with annular recess in lower outer toroid, then, filling liquid metal in the depression in downward outer toroid, then, take
Outer toroid is tipped upside down in the upper outer toroid of filling liquid metal, and finally, upper outer toroid and lower outer toroid are welded together.It is upper outer
Above and below annulus and lower outer toroid it is stitched together after, form the outer toroid, two depression faces, form the middle cavity.
