The NMRV050 speed Machining of the gearbox To make a worm gearbox, first take a blank of an alloy. A bronze bearing is made in the center of the blank. The hobbing cutter is then used to reduce the diameter of the blank relative to the finished height of the tooth tip on the gear wheel, so the depth of the cut needs to be added to the blank’s diameter. The necessary threading tool is grind to cut the worm. The side clearance on the left-hand side of the cutter tip is allowed for the worm’s pitch angle. The best finish is put on the cutting tool using a slip stone. Gear blank is then mounted on a turntable that acts as a bearing support. This bearing support is mounted on tThe quality of products is for us and for our customers of high significance. This is why we use European made components in our products. We also perform constant control of incoming materials and the control of finished products. In our company we work according to ISO 9001.he rear of the lathe cross-slide with the hobbing cutter mounted between the centers. The two worms are then machined, out of which one is made the cutter and finally the cutter is used to machine the worm gear.reducer Motor – Double extension worm shaft

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
