Housing material:
Our PTO drive shafts enable the user easy maintenance. The greasing nipples on standard crosses are positioned under angle to enable the user better access. Easier access is also possible because of the flexible cone. We listened to the wishes of our customers and placed the greasing nipple at wide-angle PTO’s into the cross bearing. The other novelty, we introduced with wide-angle PTO drive shafts is in line greasing. We wanted to additionally simplify the maintenance and extend the lifespan of joints. -

The output subassembly, which includes the worm gear and bearing cups and EPG s, loads onto a separate station for two simultaneous measurements. The machine applies a predetermined load to opposing bearing cups and measures the total stack height. At the same time, a master worm engages and oscillates the output worm gear to find the exact center of curvature for the gear teeth. The machine then measures the distance between this centerline and the rear-bearing cup.0.25kw 1400rpm |

Notice for ordering:
1) when ordering,please refer to the details of the products and tell us the exact type your need according to your requirements,like input speed,output torque,configuration,installation,etc:the installation position of the products in the order should accord with your actual needs,otherwise, it will result in oil leakage, which will impact the serving life of the products negatively.if there is special requirement to the installation position,please stress it and inform us.
2) to attain the excellent state of the variators, the common working speed should be chosen in the middle position,instead,it ismot appropriate to choose in the positions of min,or max.speed
3) if your requirements of worm gearbox or speed variator are different from shte standard products as in the catalogue,like:some portion that should be customized or mounted with special motors,please inform us in advance
