Embodiment
As shown in Figures 1 and 2, the felt gear 2 in the utility model is by felt blank through being cut into, and its profile and structure are identical with structure with the profile of ordinary gear on the market.Felt gear 2 immerses and has lubricant grease.
In addition, the groove 22 in felt gear 2 between adjacent two teeth 21 offers the grease injection channel 23 running through its inside.Wherein, the through hole 4 that groove 22 is offered by grease injection channel 23 and the home position at felt gear 2 is connected.
Due to felt oil suction, along with the engagement of felt wheel and rack, lubricant grease is just stained with on tooth bar, plays the effect of lubrication in real time, reduces tooth surface abrasion, improve the working life of gear, tooth bar.
As shown in Figures 1 to 6, the utility model comprises gearcase 1, felt gear 2 and rotating shaft 3, gearcase is provided be respectively used to assemble felt gear and assemble position 12 with the gear of rotating shaft and position 13 is assembled in rotating shaft.Gearcase 1 also offers the bolts assemblies hole 14 through its inside, and wherein, bolts assemblies hole 14 is arranged on the lower end of rotating shaft assembling position 13.
