RV worm reducer: commonly known as aluminum square box. Its cabinet is square. It is a single-stage speed up to 1/100 can be done, input and output to 90 degrees, the efficiency of 70% to 75%. Cheaper prices. Faster production cycle. Lightweight, compact and efficient; good heat exchange performance, fast heat dissipation; easy to install, flexible and nimble, superior performance, easy maintenance and overhaul; RV worm reducer features: Worm unique self-locking function, as the prototype of the box, you can save installation space. Output steady, high efficiency. Fast heat dissipation. Reduction ratio. Suitable for food packaging machinery, automatic welding equipment. WP worm reducer Features: box with gray iron 200 (HT200), high strength, maximum 250. The center distance can be done at the same time he is VF / RV / S series reducer in the largest carrying capacity. Cheaper prices. Suitable for a variety of work environments. Cycloid machine features: he is driven by an eccentric bearing cycloidal disc. Eccentric morning turn around, turn cycloid disc format. Thus boosting the output shaft, to decelerate purposes. It's more efficient than worm reducer, slightly lower than helical gear reducer, born in its cycle of fast and affordable.
