Product Description

Technical Features

  The high degree of modularity is a design feature of SRC helical gearboxes range. It can be connected respectively with motors such as normal motor, brake motor, explosion-proof motor, frequency conversion motor, servo motor, IEC motor and so on. This kind of product is widely used in drive fields such as textile, foodstuff, ceramics packing, logistics, plastics and so on. It is possible to set up the version required using flanges or feet.


Products characteristics 

  SRC series helical gear units has more than 4 types. Power 0.12-4kw; Ratio 3.66-54; Torque max 120-500Nm. It can be connected (foot or flange) discretionary and use multi-mounting positions according to customers requirements.

Ground-hardened helical gears;

Modularity,can be combined in many forms;

Aluminium casing, light weight;

Gears in carbonize hard, durable;

Universal mounting;

Refined design,space effective and low noise

  If driven by the external gearing,1400r/min or lower rotation speed is suggested so as to optimize the working conditions and prolong the service life.Higher input rotation speed is permitted, but in this situation,the rated torque M2 will be reduced


4.5 Service factor fs


The effect of the driven machine on the gear unit is taken into account to a sufficient level of accuracy using the service factor fs. The service factor is determined according to the daily operation time and the starting frequency Z. Three load classifications are considered depending on the mass acceleration factor. You can read off the service factor applicable to your application in following figure. The service factor selected using this diagram must be less than or equal to the service factor as given in the performance parameter table.
