Abstract
The utility model discloses an abrasion resistant gear, which belongs to the part of a mechanical transmission mechanism and comprises a tooth drum and teeth arranged on a tooth drum. An abrasion resistant layer is adhered to the teeth. The thickness of the abrasion resistant layer is from 0.3 mm to 3mm, which is formed by the laser cladding of ferrous alloy or cobalt-base alloy. The abrasion resistant layer covers the tops of the teeth in a fusing manner and has good abrasion resistant performance in the use process. The abrasion resistant layer is tightly combined with the teeth, does not tend to fall and has long service life. The abrasion resistant layer is the ferrous ally or the cobalt-base alloy of the laser cladding and has the advantages of simple technology and low cost.
Description
Technical field
The utility model belongs to the component of mechanical transmission mechanism, is specifically related to a kind of gear.
Technical background
Gear mechanism is one of driving mechanism the most widely of using in the modern mechanism, and its transmission is accurate, steady, mechanical efficiency is high.In the gear transmission process, one of main failure forms is the wearing and tearing of contour surface.The wealthy wearing and tearing of tooth are under the lubricating status condition of poor, the result of abrasive particle fretting wear and two principal element effects of fatigue, friction and wear.Gear geometric features after the heavy wear changes, and backlash increases, and causes that transmission is not steady, can cause broken teeth when serious.At home and abroad, for improving the wear resistance of gear surface, the general scheme that adopts is to seek schemes such as novel anti-attrition high-abrasive material, raising surface finishment, employing surface treatment new process, purpose is the prolongation service life of gear, improves its wear-resisting property, but most process-cycle of these schemes is long, expense is high.
The model utility content
To be solved in the utility model is the problem that the process-cycle is long, cost is high of existing wear-resisting type gear, and a kind of wear-resistant gear simple and easy, that cost is low of processing is provided.
The utility model is realized in the following manner:
A kind of wear-resistant gear comprises the tooth drum, and the tooth drum is provided with denticle, and denticle is attached with wearing layer outward.
The thickness of described wearing layer is 0.3～3mm.
Described wearing layer is the wearing layer of ferrous alloy or cobalt base alloy laser melting coating.
The utility model has wearing layer in the cladding of denticle top, and wear resistance is good in the using process; Wearing layer and denticle be in conjunction with closely, and difficult drop-off, life-span are long; Described wearing layer is that laser melts ferrous alloy or the cobalt base alloy that covers, and processing technology is simple, at the bottom of the cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises tooth drum 1, and tooth drum 1 is provided with denticle 2, the denticle 2 outer wearing layers 3 that are attached with.
The thickness of described wearing layer 3 is 0.3mm.
Described wearing layer 3 is wearing layers of ferrous alloy or cobalt base alloy laser melting coating.
The thickness of described wearing layer 3 is 1mm, and other is with embodiment 1.
The thickness of described wearing layer 3 is 2mm, and other is with embodiment 1.
Embodiment 4
The thickness of described wearing layer 3 is 3mm, and other is with embodiment 1.
