DFY hard tooth surface reducer

When installing the DFY hard tooth surface reducer, the middle part with a keyway is used to install the gear, which is fixed radially through the shoulder and shaft sleeve. At the same time, we also need to reserve axial clearance. The details are as follows:

Bearings are generally used in pairs and installed in opposite directions. They have an adjusting nut on the shaft and leave some axial clearance during installation to prevent the bearings from getting stuck due to temperature rise and expansion during operation, which could damage the equipment. The size of the gap depends on the weight of the load, that is, the size of the bearing.

After using the bearing for a period of time, the bearing clearance should be readjusted, otherwise it will accelerate the damage of the bearing.
In addition, the shaft and the housing or bearing seat where the bearing is installed, as well as other load-bearing parts in the bearing device, must have sufficient rigidity because the deformation of these parts will block the rolling of the rolling elements and cause the bearing to fail prematurely.
The model and specifications of DFY hard tooth surface reducer must meet the conditions of strength, thermal balance, and radial load bearing capacity of the shaft extension part, in order for the equipment to be suitable for everyone's use.
We also need to regularly maintain and repair the DFY hard tooth surface reducer in order to effectively extend the service life of the equipment.
