Shaft mounted speed reducers offers unlimited installation flexibility, it is to be mounted with a tie-rod, shaft mounted speed reducers are satisfy a wide range of output speeds and horse power requirements.

Speed reducers consists of hardened precision - machined alloy steel helical gears mounted on micro finish shafts supported on long life precision bearings with the capacity to handle maximum loading. The two - piece close grain c. I. Housing provides sturdy support and insures permanent accurate alignment of all components.

Shaft mounted speed reducers is metric in design and agma standards have been adopted wherever required speed reducers is manufactured in 10 different sizes and have gear ratios of 5:1, 13:1 and 20:1.

optional extra :

Backstops : Backstops are optional accessory and are available for all units. Backstops are designed and incorporated to prevent reversal of rotation or back run without backlash in applications such as conveyors, bucket elevators, fans, rotary pumps and kilns. . The installation and dismantling of backstop has to be done as per the steps in installation manual.

Helical speed reducers is the modern development and designed specially for use on systems for single screw extrusion of various materials such as plastic and rubber. It is also widely used in plastic blow molding machines.

it is an innovative and progressive approch to overcome the problems of separate alignment of electric motor, gearbox and transmission line. Spherical thrust bearing housing within the gearbox eliminates the requirement of separate thrust bearing housing and will provide capacity to take screw thrust. This convenient thrust arrangement is integrally mounted within the single piece reducer unit to produce a rugged, compact package for all your extruder requirements. The inline direct assembly of hollow output shaft to screw barrel of the machine saves ample space and makes installation easy the screw can be removed without disturbing barrel and reducer.

helical reducers have modular design with a normal reduction ratio ranging between 10:1 and 15:1. The single piece close gain c. I. Casting gives a rigid robust construction and incorporates high precision case hardened and ground helical gear train for improved torque transmission.

our extruder gearboxes are designed for maximum screw pressures. The spherical thrust bearing / taper roller bearing system carries reverse thrust load generated by differential pressure during molding process. important features of this design

rigid single piece thrust housing spherical thrust / taper roller bearing. dual output shaft oil seals for severe continuous duty applications. gear ratio of 10:1 and 15:1 water cooling option available which is in-built.

water cooling reducer's thermal capacity can be increased by the addition of water cooling coils. “ingeco” water cooled units are extremely compact requiring no more space than non cooled units of the same centre distance.

selection procedure based on the screw size, shank size and your motor input power, select the appropriate reducer size from the extruder drive selection table below.

lubricants simple, positive splash type lubrication system supplies all moving parts with continuous ample oil flow. Lubricating oils for the use in drives must be selected from approved list of lubricants available in the gearbox manual which is supplied along with each unit. the exceptional performance, rugged reliability, and compact size of the extruder drive reducer unit makes this your best choice for long life and low maintenance.
