Precision Worm Reducer

Information on servo precision worm reducer products

Precision worm reducer

Dual Lead Box is a servo motor precision worm reducer which can reduce and correct the increase of back lash with the passage of time.

01

Using powerful taper roller bearing to provide high strength
The two input and output taper roller bearings guarantee maximum bearing life by securing continuous precision even when the internal temperature increases.

02

Providing perpendicular allowable load at the higher shaft with taper bearing at the output shaft

03

Providing various levels of back lash at the output terminal
Premium: less than 1 minute of back lash / S-Medium: less than 3 minutes of back lash / Medium: less than 5 minutes of back lash / S-Basic: less than 7 minutes of back lash / Basic: less than 10 minutes of back lash

04

Shrink disc, anti-slippery function, precise torque transmission, possible to deliver more accurate angle than key type

05

Aluminum (alloy) case: Casted with heat-treated aluminum to be very strong with light weight

06

Disc coupling: simple motor assembly, easily assembled with various motors, prompt shock absorption

07

Optimal effect of worm and worm wheel, special alloy
The latest assembly technology and gear cutting process enabling about more than 80% of surface contact reducing contacting pressure
Improving wear resistance with the unique technology of dual lead box
Guaranteeing a long life with more than 80% of contacting pattern and low back lash

08

Semi-permanent use not replacing lubricant with high performance synthetic lubricant (Mobil Glygoyle 30), possible to discharge gas from the air vent at each side
