Worm Gear Units
Products Characteristics
1. Made of high-quality aluminum alloy, light weight and non-rusting.
2. Large output torque.
3. Smooth in running and low in noise, can work long time in dreadful conditions.
4. High in radiating efficiency.
5. Good-looking in appearance, durable in service life and small in volume.
6. Suitable for omnibearing installation.
Main Materials
1. Housing: die-cast aluminum alloy(frame size 025 to 090);cast iron(frame size:110 to 150):
2. Worm: 20Cr, carbonize&quencher heat treatment make the hardness of gear’s surface up to56-62HRC,retain carburation layer’s thickness between 0.3 and 0.5mm after precise grinding.
3. Worm wheel: wearable stannum bronze alloy.
Surface Painting
Aluminum alloy housing:
1. Shot blasting and special antiseptic treat-ment on the aluminum alloy surface.
2. After phosphating, paint with RAL5010 blue or silvery white paint.
Cast iron housing: First paint with red antirust paint, then paint white RAL5010 blue or silvery white paint.
UDL Series
The design of UDL series stepless speed variator compromises the advanced technology both at home andabroad.The products include the following main characteristics:
1. High speed precision:0.5-1 shaft2. High speed-changing range: The speed ratio ranges from 1:1.4 to 1:7 freely.3. High in strength and long in service life.
4. Convenient to regulate the speed.
5. Continuous in running, front-to-back in running direction, smooth in driving, stable in performance andowin noise.
6. Full in sealing and suitable for any environment
7. Compact in structure and small in volume
8. Made of high-quality aluminium alloy diecast into forming, good-looking in appearance, light in weight
and it never gets rusty
9. Good in adaptation:UDL series stepless speed variators can be combined with all kinds of speed reducersas to achieve low stepless speed-changing.
UDL series stepless speed variators are widely used for foodstuffs, packing, chemicals, pharmacy.plastics, paper-making, machine-tools, communications, and all kinds of automatic lines, pipelines andassembly lines which need speeregulation, It is a good companion for production.
PC Series
The PC construction is modular and therefore it can be as a separate unit mounted on any type of fittedgeared motor(PAM), whose the variouspossibilities of flange/output shafts can be found on page 21.Fitting the pre-stage helical module on the main reduction unit is easily done as for any motor of type B14.The prestage unit cannot be used by itself, but only coupled with another reducer unit.
Main Materials
Case in aluminium alloy. Gears:40Cr, machined accurately base on the accurate.correctly fitting the pinion on the electric motor shaft requires you keep to the following instructionsa. Thoroughly clean the electric motor shaft;
a. Thoroughly clean the electric motor shaft;
b. Remove the motor key from its seat;
c. Fit the bush 1 to the drive shaft as shown in the diagram to make this easier, you can heat the bush to approximately 70/80°C :
d. Fit the new key3 provided in place of the one removed beforehand:e. Fit the pinion 4 taking the same precautions as described in point c;
f. Fit the washer 5 and tighten with the screw6;
g.Remove the rubber cap mounted on the seat of the oil seal, taking care since the prestage unit is already complete with lubricant;
h.Fit the oil seal 2 and then the motor assembly, taking care not to damage the lip of the oil seal.
