SINGLE STAGE EXTRUDER GEARBOX

S U M I T G E A R S “ S B E ” S E R I E S Extruder Gearboxes are double reduction parallel shaft are available in horizontal and vertical models are used in single screw extruder machines.

The gear units are capable to transmit the high torque required for pressurising and plasticising moulding materials.

Also have capability of absorbing the high axial thrust load induced by the process, through built in spherical roller thrust bearing.The units can be offered in left hand (L.H) or right hand (R.H) configurations with horizontal and vertical mounting as per customer requirements.

Advantages of an Extruder Gear Box

High torque transmission: Extruder gear boxes are designed to handle high torque loads, allowing for the extrusion of materials with high viscosity or resistance. This ensures efficient material processing and product quality

Precise control and uniform output: The gear reduction and torque multiplication provided by the extruder gear box allow for precise control over the extrusion process. This results in consistent product dimensions, surface finish, and overall quality.

Versatile applications: Extruder gear boxes are used in a wide range of extrusion processes, including plastic extrusion, rubber extrusion, and food extrusion. They can be adapted to accommodate different materials and extrusion requirements.

Our extruder gearboxes including single screw extruder and dual gear extruder units are designed to handle the high torque transmission required for pressurising and plasticising moulding materials. They also effectively absorb high axial thrust loads using built-in spherical roller thrust bearings. The SBE series offers variable options to accommodate appropriate thrust bearings. The corresponding output shafts feature spline attachments.

Durability and reliability: Extruder gear boxes are built to withstand the demanding conditions of extrusion processes, including high temperatures and high torque loads. They are designed for long service life and minimal maintenance

FEATURES

SUMIT GEAR “SBE” SERIES are in Modular concept of construction, Double stage in 13 sizes with ratio from 6.3:1 to 22.5:1.

Torque. range. for double Extruder 1.8 to 60.7 KNm.The unit are in supplied in split housing. “SBE” SERIES gearboxes are fully metric..

BEARINGS

Antifriction Roller bearings from major manufacturers are used through out .Sumit Gear prefers self-aligning spherical roller thrust bearing 294-E series.

LUBRICATION:

In horizontal units, lubrication in most instances is by transfer of oil by gears dipping in the sumps of gear unit bases.In vertical unit, lubrications in most instances are provided by a pump driven by input shaft.It is necessary to use a forced lubrication system with a separate oil tank for specific applications.
