Flender/Flender Gear Units/Bevel-helical speed reducer B3

rchas ers interest is long life operation of gear unit and if there are several gear units wi th the same price, priority should be given to those gear unit which is more durable. How ever, if the price is the only interest, and it is the usually case, then economic have to decide. Of course, the price is market category and sometimes it doesnt epresent the real value of gear unit. The price can be much lower than real, when he manufacturers want to obtain new costumers. Also, the price can be much higher hen the gearbox belongs to famous trade mark and when the customer is secured about its quality and doesnt ask about the price. This adoption procedure is rather complicated and till not enough defined. 5. GEAR UNITS ADOPTION CARRIED OUT BY GEAR UNITS DE SIGNERS When defining conception of motor gear units, desig ners, also, carry out adoption of gear units, ie. they have to determine one concept solution which will be in advantage regarding to other competitive solu tions. The basic parameters during this process, in the frame of equal shaft he ight, are the value of maximum output torque ( TNmax ), the value of the biggest speed ratio ( umax ), mass of gearbox, overall dimensions, power losses in gearbox, mounti ng types and positions, etc. For example, if load capacity ( TN) of two-stages gear unit is observed, it can be no ticed that different manufacturers have different values, in the frame of the same shaft height (Fig. . Regarding just load capacities of different solutio ns of gearboxes, it can be concluded that the most favourable solution is gear unit of manufacturer . However, it can not be always the case, so speed ra tios have to be taken into the consideration. Some manufacturers tend to achieve arge values of both load capacity and speed ratio of gear units. Other manuf acturers produce gearboxes with great load capacities in the frame of small sp eed ratios, so that their solution is good for customer, but ba
