Wherein the employed chain roller of chain configurations as shown in Figure 4, this chain roller A need have higher hardness and wear resistance, want to bear bigger moment of torsion, good fatigue resistance, general extensive employing be the chain roller A of medium carbon alloy steel, its advantage is: can bear bigger moment of torsion, guarantee not split in use, dimension Ke Shi hardness (HV) is 800, has certain wear resistance.Right its deficiency is: cementation zone is very shallow, wears no resistance lastingly, and chain roller weight is heavier, and the chain wear deformation effect is used, so there is improvement necessary.
The model utility content
Because the disappearance of known chain roller, the purpose of this utility model is to provide a kind of chain roller structure of chain, hardness and wear resistance performance when contacting with other assembly to reduce the weight of chain roller, to strengthen it.
For achieving the above object, solution of the present utility model is:
A kind of chain roller of chain structure, this chain roller is to be the cirque body of base material with the titanium, it is 1500 to 3800 hardened layer that toric surface is provided with one dimension Ke Shi hardness (HV) scope.
Above-mentioned hardened layer is that titanium nitride (TiN) layer, chromium nitride (CrN) layer, titanium carbonitride (TiCN) layer, TiAlN (TiAlN) layer or class are bored any in carbon (DLC) layer.
The thickness of above-mentioned hardened layer is 1-4 micron (μ m).
Above-mentioned hardened layer is 0.05 to 0.4 with respect to the friction factor of steel.
Above-mentioned hardened layer is the rete that sputter forms.
The highest application of temperature of above-mentioned hardened layer is 350 ℃ to 800 ℃.
The color of above-mentioned hardened layer is to be any of gold look, blueviolet, silver grey, atropurpureus or black.
After adopting such scheme, the utility model can have the following advantages:
1. the utility model is specially adapted to all kinds of chain roller structures, be to be provided with a hardened layer in chain roller surface, its dimension Ke Shi hardness (HV) is 1500 to 3800, with respect to the friction factor of steel only 0.05 to 0.4, can provide the chain roller enough wear resistance performances, prolong the working life of chain roller.
2. chain roller of the present utility model is to be base material with the titanium, its weight is 0.237 gram only, originally, chain roller weight 0.41 gram that adopts alloyed steel to make is light, that is the utility model can reduce the weight of chain roller, lower the wearing and tearing of chain roller and chain sheet, be provided with titanium nitride layer in the surface of chain roller again, improve the lasting wear resistance of chain roller.
3. titanium nitride layer of the present utility model is the rete that sputter forms, sputter is an environmental protection processing procedure, can produce waste liquid unlike electroplating, cause environmental pollution, but and have the low large-area coating film of process temperatures, advantage such as processing procedure speed is fast, production reliability is high, following process is easy.

Embodiment
The utility model embodiment, chain roller structure for a kind of chain, shown in the longitudinal sectional view of the D structure figure of Fig. 1 and Fig. 2, chain roller 1 is circular, form the holding part 11 of hollow in its caliber, and be base material 12 with the titanium, this chain roller 1 surface is provided with a hardened layer 13, the rete that this hardened layer 13 forms for sputter, the suitable environmental protection of its processing procedure, can produce waste liquid unlike electroplating, cause environmental pollution, it is low that sputter has process temperatures simultaneously, but large-area coating film, processing procedure speed is fast, the production reliability height, advantages such as following process is easy, the mode of its sputter is selected from the dc sputtering method, radio frequency sputtering method or magnetic control sputtering plating method wherein any, this hardened layer 13, any one in can following material made, and its physical property is as shown in the table:
| Title | Dimension Ke Shi hardness (HV0.05) | Thickness (micron) | Friction factor (with respect to steel) | The highest application of temperature |
| Titanium nitride | 2700 | 1-4 | 0.4 | 550℃ |
| Chromium nitride | 1500-2200 | 1-4 | 0.1 | 600℃ |
| Titanium carbonitride | 3000 | 1-4 | 0.4 | 450℃ |
