Product Introduction:

The 48-tooth planet carrier (reference number 395-3116) is a structural component used in planetary gear assemblies. It serves as the mounting base for the planet gears and transmits torque between the sun gear, ring gear, and output shaft.

1. Installation Location
The planet carrier is installed inside the planetary gear set housing, typically within a final drive, wheel hub, or transmission assembly. It positions the planet gears in mesh with the sun gear and ring gear, and is connected to the output shaft or hub to deliver power.

2. Function
The carrier holds the planet pins and gears in precise alignment, allowing the planet gears to rotate and orbit simultaneously. It transfers the combined torque from the planetary gear train to the output component, enabling speed reduction and torque multiplication. The 48-tooth design refers to the internal spline or gear tooth count, which determines the gear ratio and load capacity.

3. Maintenance and Service
Regular inspection includes checking the carrier for cracks, wear on the planet pin bores, and spline damage. If the carrier shows signs of deformation, excessive bearing wear, or tooth damage, replacement is required. The carrier is a precision-machined component and must be installed with correct bearing preload and gear backlash; assembly should be performed by qualified technicians.

4. Important Notes
Verify the reference number 395-3116 against the original equipment manufacturer's catalog to confirm compatibility with the specific machine model. Use only the specified bearings, pins, and lubricant during installation. After assembly, check gear mesh patterns and confirm smooth rotation before returning the equipment to service.
