Abstract
The utility model discloses a kind of wear-resistant elevator traction sheave, including：Wheel body, the wheel body periphery is provided with several cell bodies, each cell body is annular, the ceramic substrate of an annular is provided with the cell body of each annular, the body pad outer surface is provided with grooving, the section of the radial direction of the grooving of annular is circular arc, and several cell bodies are axially equidistantly arranged successively along the wheel body.By the way that the cell body of the body surfaces of existing cast iron quality is embedded in into ceramic substrate, ensure that steel wire rope no longer contacts with Cast Iron Surface, but the ceramic substrate surface for being more than steel wire rope with hardness contacts, ensure that wheel body will not be worn, simultaneously because ceramic hardness is big, for a long time using will not also be worn, it possesses smooth surface, and the degree of wear can also reduce during the use in steel wire rope later stage.
Description
Technical field
It the utility model is related to a kind of traction sheave, more particularly to a kind of wear-resistant elevator traction sheave.
Background technology
Traction sheave is traction machine important component in elevator, and it is the rope sheave on traction machine, also referred to as traction rope sheave or drive rope sheave.
It is the device that elevator transmits traction power, using the frictional force passing power of grooving on traction steel-cable and traction wheel rim, is mounted in
On worm-wheel shaft in decelerator.
Because steel wire rope is that steel wire strand is twisted together, its surface is more coarse, for a long time in the wheel with cast iron quality
In body friction process, mutually worn between wheel body and steel wire rope, reduce both service life.
The content of the invention
The utility model overcomes the deficiencies in the prior art, there is provided a kind of wear-resistant elevator traction sheave.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of wear-resistant elevator traction sheave, including：
Wheel body, the wheel body periphery are provided with several cell bodies, and each cell body is annular, it is characterised in that each annular
Be provided with the ceramic substrate of an annular in cell body, the body pad outer surface is provided with grooving, annular it is described
The section of the radial direction of grooving is circular arc, and several cell bodies are axially equidistantly arranged successively along the wheel body.
In one preferred embodiment of the utility model, the ceramic substrate of each annular is by two semi-circular shape
Ceramic body is spliced.
In one preferred embodiment of the utility model, the section of the radial direction of the cell body of annular is trapezoidal.
In one preferred embodiment of the utility model, the section of the radial direction of the ceramic substrate of annular also to be trapezoidal,
And the ceramic substrate can be seamless in the cell body.
In one preferred embodiment of the utility model, it is provided with the surface that the ceramic substrate contacts with the cell body convex
Rise, be provided with recessed pit on the cell body inner surface, the projection can position correspondingly in the pit.
In one preferred embodiment of the utility model, bonded between the ceramic substrate and the cell body by adhesive.
In one preferred embodiment of the utility model, the wheel body is made by cast iron.
The utility model solves defect present in background technology, and the utility model possesses following beneficial effect：
（1）By the way that the cell body of the body surfaces of existing cast iron quality is embedded in into ceramic substrate, ensure steel wire rope no longer
Contacted with Cast Iron Surface, but the ceramic substrate surface for being more than steel wire rope with hardness contacts, and ensures that wheel body will not be worn, simultaneously
Because ceramic hardness is big, for a long time using will not also be worn, it possesses smooth surface, during the use in steel wire rope later stage
The degree of wear can also reduce.
（2）Cell body designs in echelon, convenient accommodating ceramic substrate, and by raised and pit structure matching, ensures
Ceramic substrate will not produce relative slip between cell body, further be bonded using adhesive, and structure is more stable.

Fig. 1 is the sectional structure chart of preferred embodiment of the present utility model；
Fig. 2 is the sectional structure chart without embedded ceramic substrate of preferred embodiment of the present utility model；
Fig. 3 is A partial enlarged drawings in Fig. 1；
In figure：1st, wheel body；2nd, cell body；3rd, ceramic substrate；4th, grooving.
Embodiment
The utility model is described in further detail presently in connection with drawings and examples, these accompanying drawings are simplified
Schematic diagram, only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the structure relevant with the utility model
Into.
As shown in Figure 1, Figure 2 and Figure 3, a kind of wear-resistant elevator traction sheave, including：Wheel body, wheel body periphery are provided with some
Individual cell body, each cell body are annular, and the ceramic substrate of an annular, body lining are provided with the cell body of each annular
Pad outer surface is provided with grooving, and the section of the radial direction of the grooving of annular be circular arc, several cell bodies along wheel body it is axial according to
Secondary equidistantly arrangement.
By the way that the cell body of the body surfaces of existing cast iron quality is embedded in into ceramic substrate, ensure steel wire rope no longer with casting
Iron surface contacts, but the ceramic substrate surface for being more than steel wire rope with hardness contacts, and ensures that wheel body will not be worn, simultaneously because
Ceramic hardness is big, and for a long time using will not also be worn, it possesses smooth surface, is worn during the use in steel wire rope later stage
Degree can also reduce.
The ceramic substrate of each annular is spliced by the ceramic body of two semi-circular shape, and the end of splicing, which passes through, glues
Jelly bonds.The section of the radial direction of the cell body of annular to be trapezoidal, the section of the radial direction of the ceramic substrate of annular also to be trapezoidal,
And ceramic substrate can be seamless in the cell body.Projection is provided with the surface that ceramic substrate contacts with cell body, in cell body
Be provided with recessed pit on surface, projection can position correspondingly in pit.Lead between ceramic substrate and cell body
Cross adhesive bonding.
Cell body designs in echelon, convenient accommodating ceramic substrate, and by raised and pit structure matching, ensures ceramics
Pad will not produce relative slip between cell body, further be bonded using adhesive, and structure is more stable.
Wheel body is made by cast iron, and wheel body is provided with axis hole at axle center.
It is above enlightenment according to desirable embodiment of the present utility model, it is complete by above-mentioned description, related personnel
Various changes and amendments can be carried out in the range of without departing from this item utility model technological thought.This item utility model
