Worm Power Drive EW/EWM, EWJ/EWJM series
- Achieves a high balance of performance, efficiency, and cost, while also achieving high precision and compactness.
- Based on Foot mount, both solid and hollow output shafts are available.
- The solid type is ideal for coupling fastening and chain/belt drives.
- A wide variety of options make it possible to make equipment more compact.
Features
-
・High balance of capacity, efficiency and cost
While using Cylindrical Worm, this is a highly balanced worm that combines performance, efficiency, and cost at a high level by leveraging years of technology to maximize the transmission capacity of the tooth surface.
-
-High efficiency and energy saving
In order to achieve good sliding transmission with an emphasis on efficiency, the optimum tooth surface shape has been pursued to achieve high efficiency with minimal meshing loss.
-
・Longer oil seal life achieved - Adopts a unique new oil seal structure
The new oil seal structure incorporates a filter inside the oil seal, which prevents Wear debris from entering the seal, extending the seal's lifespan.
-
・剥離に強い静電粉体焼付塗装 (※EWJ70(一段減速)以下のもの)
We use epoxy polyester paint that does not contain thinner, making it environmentally friendly.
It improves paint adhesion and makes the paint more resistant to scratches and peeling, reducing the risk of foreign matter contamination.
・脚取付/ベースマウントで出力軸は中実軸・中空軸が選択可能です。
· Small to medium sizes available (center distance 25 to 200).
・EWJシリーズは据付方向自由の専用ケースを採用しています。
