2. Product development:
Wuxi TRUMY has the ability to continually develop and test special couplings for different industries. Backed by more than 30 years of dry coupling manufacturing experience, the company has developed a new generation of locomotive couplings for the rail transit industry. Dynamic fatigue test benches and continuous torque slip test benches with complete range of models and wide coverage are used for product verification in conjunction with advanced simulation analysis methods, to provide users with transmission products of very high reliability and safety. Special anti-corrosion measures are adopted to extend the product maintenance cycle and reduce extra cost of maintenance and downtime.
3 . Product application presentation (I) — Flexible disc couplings for locomotives
（1）Applications
Four-bolts , for monorail urban rail transit vehicles, connecting traction motor and reduction gearbox;
Six-bolts, for train locomotives and wagons, connecting traction motor and reduction gearbox;
Eight-bolts, for magnetic direct-driven locomotives and wagons, connecting traction locomotive wheel pairs;
（2）Product features
Reliable anti-loose locking fasteners
Special anti-loose structure is adopted for different structures, and the reliable effect can ensure safe connection.
Face gear connection
Face gear connection is used for six bolts and eight bolts laminated flexible couplings, to realize shaft-through structure with separable spacer shafts, greatly increasing the radial compensation of couplings.
High compensation value
Six bolts and eight bolts flexible
disc couplings feature large angular compensation, much higher than that of other flexible disc couplings of the same size and type.
Torque overload protection
Torque overload protection is adopted for six-pass and eight-pass laminated flexible couplings, to effectively ensure safe operation of equipment under overload torque status.
4. Product application presentation (II) — Diaphragm flexible couplings for locomotives
Applications
Diaphragm flexible couplings are in single diaphragm structure, and can be used in low deck rail transit vehicles, to connect traction motor and reduction gearbox.
Product features
In addition to support the half weight of motor rotor, the diaphragm flexible couplings also restrict its axial position, and withstand the vibration and impact from the motor rotor in operation. They are designed with torque overload protection device, to avoid transmitting excessively high torque to the gearbox in case of motor short-circuit, to ensure the safety of gearbox.
5 Product application presentation (III) — Gear type couplings for locomotives
Applications
Normally they are used in powered cars in metro and railway, connecting traction motor and reduction gearbox.
Productfeatures
The couplings are in special drum shaped gear structure, to compensate for very big axial, angular and radial misalignment between the motor shaft and gearbox input shaft while transmitting power in operation.
