Electric Cylinders CERTIFICATE No. 2033535 DUTCH COUNCIL FOR ACCREDITATION Linear Actuator Technology Product Selection Guide

CONTENTS / INTRODUCTION Electric Cylinders are universal drive systems lor a wide range of Inear reciprocating motion An electric cylinder is basically a mechanical screw jack. However the screw is fully enclosed by push rod which is guided in protection tube. Varieties of options are possible using choice of front attachments, swivel bases, motor flanges, Gears & Gear Dri/es, with over 30 years of experience, provde products, solutions and services in power transmission technology. Other Producers of Geais & Gear Drives include Electro mechanical Linear Actuators, Bevel Geo' Screw Jacks. T...

Wide Rang* Bectric Cylinders can be used for all lifting, lowering, traversing and swinging application. Adoption to all kinds of requirements is possible due to wide rang* of lifting force fromSkNra S50 kN. Lrrttng Syftsrm Possibilities of combining electric cylinders with bevel pear boxes, geared motors mo*ea It easy to design ifrina Electric Cylinders are available as upright version with or without swivel base. Various typos of front attach merits are available foi connecting to toad Various applications examples are: > Lifting road/roil equipment > Automobile repair shop >■ Height...

DESIGN PRINCIPLE Thrust tall Booing StcwxJwd Head Protection lube Tapered Roller Bearing Swivel Bate

DESIGN PRINCIPLE Housing houses reduction gear drive, thrust bearings, screw and lubricant. Adequately ribbed housing is made ot aluminum alloy in smaller sizes and high grade spheroidal graphite iron in larger Sizes. It is machined to high accuracy for interchangeable Lifting Screw Lifting Screw is made of medium carbon steel, hardened and tampered to withstand various types of loads encountered in lifting The non rising screw makes the nut to move which lifts the load. Protection Tube The push rod is guided by an external protection tube and Is screwed to the Swivel Base A swivel base...

APPLICATION GUIDE Axial Play The axial play between screw and nut threads is maintained between 0.) and 0.2 mm. This is an intentional play for smooth working. In operation this wil I increase due to Pitch Error of Lifting Screw The pitch error of screw is due to monufac turing process and is approximately */- 0.05 mm over 300 mm. this error has almost no >Maximum permissible axial force F is given in fable, page 8. These values are applicable when stock loads or lateral loads do not exist. When heavy stock loads exist, multiply the axial force by stock load factor upto 2 and select...

APPLICATION GUIDE >There are fhree efficiency roHos: > Efficiency of Screwancl nut alone. Tofal efficiency of electric cylinder which Includes efficiency of screw and single start worm gear. > Total efficiency of electric cylinder which includes efficiency of screw and multi start worm gear. Refer Performance Table on page 8 for these efficiency values. Motor and Manual Operation Electric cylinders are basically designed for eleclric operation. However they can be operated by hand wheel or hand crank. Consider manual effort required and number of turns of input shaft for manual operation,...
