2.Main Characteristics

 1).Optimizing design is made on the gears for polygon hard-tooth-faced speed reducers in the national standard,and the actual bearing capability of some speed reducers is improved.

 2).The box-type design has broken through the thinking model in which the hard-tooth-faced speed reducers are led by curves in the national standard,and has introduced a shape of polygon led by straight lines.

 3).The polygon boxes can be mounted in any way and are adaptive widely.

 4).Small volume,light weight,low noise,high efficiency and long service life.

3.Equipment method

▲For 2-4 stage,there are all solid shaft,hollow shaft with straight key and hollow shaft with shrink disc.

▲Three kinds of inputting types,six installation faces and four installation positions.Backstop can be fixes to rotate in single direction.High power can be equipped to achieve high capacity.

(It can make up nearly 30,000 kinds of parallel shaft polygon hard-tooth-faced speed reducer)


4.Working conditions

1) The circumferential speed of the gear is not more than 20m/s;

2) Speed of high speed shaft is not more than 1500r/min;

3) The working environment temperature is - 40℃ ~+45℃.

4) It can operate in both directions.

Note:Lubrication and daily maintenance of reducer is very important, if you need to know more about it. Pls click here→→→
