Mechanical Stepless Variator Description
The Mechanical Stepless Variator has a standard modular design and special application in the engineering machine etc. the Mechanical Stepless Variator’s cone disc is built in an aluminum die-casted housing respectively for motors of IEC frame size 63, 71, and 80. The cone discs are made in case hardened bearing steel, to increase the durability of each variable speed variator.
SDT Mechanical Stepless Variator can operate in both directions, input and output shafts rotate in the same direction.
Handwheel can be fitted to both sides of the control box for convenient installation. mechanical variable speed drive
Mechanical Stepless Variator is supplied with mineral lubricant ISO VG 46, with the quantity of oil for positions B3-B5 mechanical variators
As a consequence of its operating principles, based on the satellite friction, motor variator the appropriate lubrication is essential for the correct duration and efficiency of SDT. mechanical variable speed drives. It is an electronic speed variator strictly recommended, in addition, to avoid mixing two different oil types. speed variators, If you change the type of oil, make first sure you clean the variator with appropriate chemical thinner mechanical gear reducer.
All mechanical speed variator are supplied with filler, level, and breather plugs. Before the start-up speed variator gearbox, you must place the breather plug on the top like in the following pictures variator drive.
Remark: the weight is for the main model, without oil and motor
Variable-speed variator Materials
Housing: die-cast aluminum alloy (Housing size: 025-090); cast iron (Housing size: 110-150)
