IProduct Introduction QlrtNBZI1L! s&rafeflu Fmvmm— &««=*« j&0io Series Geared Motor is the famous brand in drive field with international advanced level, including R Series Helical Geared Motor, F Series Parallel Shaft-Helical Geared Motor, K Series Helical-Bevel Geared Motor, S Sevies Helical-Worm. # IS Series productsfollowthe philosophy of modularization and optimization, adoptfinite element analysis method and unique lowe r noise technology in designing gear, to insure advanced design. The classification of ratio is so acurate that.Gear profile design for lowe rnoise level. It has millions of combinations to meet varietal demand of customers. The process from the material selection to manufacturing is strictly controled--house is beautiful and rigid casted by precision control,gear isendurable by carburizing.Take the flexible manufacturing control(FMC) in the manufacturing to realize the high precision level and free-maitenabce of products. Our corporation also provides otherproduct options such as combined geared motor, shrink disk, spline hollow shaft, B14flange, please consultourcompanyforfurtherinformation.

Mft Drive selection data Certain data are essential to specify the components for your drive.These are:

lililillll Project planning sequence Example The following flowchart diaplays a schematic view of the procedure for planning a project incorporating a positioning drive.The drive comprises a geared motor which is powered by an inverter.

Efficiency of QZ gear units The efficiency of the gear units is mainly determined by the gearing ,mash and bearing friction. Please note that the starting efficiency of a gear unit is always less than its efficiency at operating speed .This fact is especially obvious in helical-worm right-angle geared motors R.F. KijfilM R. F. K gear units £94%(3M) ~98%(1&) ±\S\o The efficiency of helical.parallel shaft and helical-bevel gear units varies according to the num -ber of gear stages,between 94%(3-stage)and 98%{1-stage). #SfiKTH*a£i The gearing in helical-worm and gear units produces a high...

Determining overhung load #5Sba#*ftfz5!l:FT*: When determining the overhung load, the type of transmission element mounted onthe shaft end must be comsidered. The transmission element factors fz are listed as follows. The overhung load exerted on the motor or gear shaft is then calculated as follows: FR gfaSiff(N) Overhung load in N Ma Torque in Nm d„ Mean diameter of the mounted transmission element in mm fz ft fib S Transmission element factor Permitted overhung load According the rate service life Lhio of the anti-friction bearings to define the permitted overhung I -oads.
