Merchandise Profile


ZLYJ collection gear box is for plastics twin-screw extruder supporting design and style precision tough-toothed surface with thrust block transmission parts. item design and style Makes use of a JB/T8853-2001 stipulated in the various complex and scope. its attribute is gear and axial elements utilized large power steel content. gear by carburizing. quenching and equipment grinding method for GB10095 – precision. equipment tooth surface area hardness 88.6 degree. HRC54-62. in hollow output shaft entrance configuration has super specs of thrust bearing. and inherit screw function kicks back again. bearing and oil seal and other main domestic substantial-good quality merchandise common elements all Employs. can also in accordance to customer want. outfitted with imported items. Etc. Characteristics. Item overall performance has achieved the advanced global level. can exchange imported merchandise use identical variety.



Relevant scope


1. high-speed pivot is not far more than 1.500 R.P.M..


two. equipment transmission circumference pace is not a lot more than 20 meters per 2nd.


three. operating atmosphere temperature of 40-forty five degrees underneath zero Celsius. if. before commencing the lubricating oil ought to be preheated to degrees Celsius earlier mentioned. this deceleration equipment can be utilised in the negative direction procedure. but some of the sort higher velocity shaft one-way pump. the default direction for: in the face of output shaft. the output shaft for clockwise. This sort of as direction alter. remember to when ordering.
