Drum spider gear LF L5031752

A drum spider gear transmits power from the motor to the mixing drum in commercial planetary mixers. The gear sits between the drive shaft and the drum, converting rotational force into smooth, consistent motion. This direct mechanical linkage ensures the drum turns at the programmed speed without slippage, allowing even blending of heavy doughs, batters and creams. The spider design distributes torque evenly across the drum's base, preventing uneven wear and extending the life of both the gear and the drum itself.

To fit the gear, the operator removes the drum, slides the spider gear onto the drive shaft, then reattaches the drum so the gear meshes with the drum's internal teeth. Once secured, the mixer is ready to run. The gear remains in place during every cycle, requiring no further adjustment until replacement becomes necessary.

The LF drum spider gear is machined from hardened steel, giving it the strength to handle continuous loads without deformation. Its external diameter of 36 mm matches the drive shaft, while the 25 mm internal bore fits over the shaft's splines. The compact size allows it to fit inside the drum's hub without interfering with the mixing action.

In practice, the external diameter determines the gear's compatibility with the drive shaft, while the internal bore must match the shaft's spline profile. The difference between the two diameters creates the gear's teeth, which engage the drum's internal ring gear. This engagement transfers power without relying on belts or chains, reducing maintenance points in the mixer.

Cleaning is limited to wiping the gear with a dry cloth after the drum is removed; no lubrication or disassembly is required. The gear is a single, non-adjustable component with no variants or options. It is specified as a direct replacement for LF commercial mixers and is listed in the drive-train section of the catalogue.
