After the standard heat treatment of the drive wheel blank of our sprocket, the hardness of the substrate reaches above HB235, and the drive teeth are subjected to medium frequency induction hardening and low temperature tempering. The surface hardness can reach HRC48-54, and the hardening depth is higher than 5-10mm (HRC45). It not only provides accurate power under harsh working conditions, but also has excellent wear resistance and has the effect of extending product life and reducing customer costs.

Inspection of sprocket oil
The function of the sprocket oil is to ensure the normal lubrication of the reducer, differential sprocket and bearings in the drive axle of the excavator. Drive axle sprocket with too much oil will increase the sprocket's running resistance and power consumption. Excessive pressure will damage the oil seals and joint seals, causing oil leakage; too little sprocket oil will cause dry friction and burnout of each sprocket. Reducer and differential sprocket and shaft cause serious mechanical accidents. For this reason, it is very important to regularly check the quantity and quality of the sprocket oil in the rear axle.
There are three ways to check the amount of sprocket oil: First, the method of judging the temperature of the axle housing, which is mainly during the driving of the vehicle, and touches the drive axle housing after stopping. If the casing becomes hot, it means that the operating temperature is abnormal and there is oil shortage. Possibly; the second is the inspection method, park the car on a flat road or field, open the inspection hole screw plug, insert the inspection hole with a hard paper strip or plastic strip, make it come in contact with the oil surface, and take it out. Below 2cm below the lower edge of the inspection hole is a lack of oil; the third is the oil drain measurement method, which is mainly used for drive axles without an inspection hole. The method is to unscrew the oil drain plug and release all the sprocket oil. Use a scale to weigh its weight or Measure its volume with a meter.
When inspecting, check the color of the sprocket oil at the same time. If the color is black, yellow or red, and there is an odor, it is deteriorated sprocket oil and should be replaced in time. If not, replace with new oil.
Replace the sprocket oil
Purchase the sprocket oil according to the type of sprocket oil specified or recommended in the user manual or service manual of the vehicle.
Start the vehicle for a certain distance to heat up the sprocket oil in the axle housing. When the sprocket oil is still warm, remove the oil drain plug and release the sprocket oil. After draining the sprocket oil, wipe the screw plug and screw it back firmly. Then unscrew the refilling plug or the oil level check hole plug, and add new sprocket oil until the sprocket oil overflows from the oil level check hole. Install the check hole plug. Drive axles without inspection holes are refueled according to the specified weight or volume.
After replacing the sprocket oil, clean the ventilation holes on the unobstructed axle housing to keep it open.
