TECHNICAL CHARACTERISTICS The housing shape has been studied to optimize the water draining during washing. From type 75 and up, 2 taper roller bearings are mounted on the wormshaft, improving the mechanical resistance to the axial loads given by the wormwheel. Moreover, the combination of this characteristic and 2 nilos (mounted on size 75 and up to keep lubrication grease inside the bearings even when they are not touched by the oil bath), or, in alternative, special RS shields on such taper bearings, permits the mounting of the whole BOX range, from the size 25 to the size 150, in the...

TECHNICAL CHARACTERISTICS Lubrication is already provided by motive with long-life synthetic oil up to size BOX90, and with mineral oil from size BOX110. REGISTERED DESIGN The gear unit is equipped with a full set of filler, level and breather plugs, permitting all mounting positions and facilitating the management of the stock. In order to increase silence, efficiency and duration, the wormshaft is made in case hardened steel and ground machined, while the worm wheel is in shell cast ZCuSn12 bronze. Before being assembled, the worm wheel is submitted to a running-in working period to...

EFFICIENCY An inherent factor in the selection wormgear boxes is the efficiency η, defined as the ratio between the mechanical power coming out from the output shaft, and the power in the input shaft: η Some reasons concurring to a reduction of the efficiency can be identified in the several forms of sliding and rolling friction. In practice, efficiency depends essentially by: · · · · · · · · helix angle material of matching parts tooth form accuracy gear finishing lubrication gear sliding speed load vibrations temperature In the combined BOX units (BOX+BOX), the total efficiency value is...

All units are supplied with plugs for loading, discharging and checking the level of the oil. Furthermore, the units The use of oil instead of grease offers remarkable improvements under the point of view of the application, especially in the effectiveness and efficiency of the lubrication in the “limit layer” condition as well as under high intermittence applications. Furthermore, synthetic oil lubrication assures a much wider range of low and high operating temperatures. With the use of synthetic oil, the temperature limits turn out to be determined by the properties of the seal material...

TECHNICAL DATA Rated output torque Mn2 [Nm] Torque output transmissible under uniform loading and referred to the input speed n1 and the corresponding output speed n2. The output torque can be calculated with the following formula: P [kW] · 9550 Mn2 = n1 n2 · ηd Torque demand Mr2 [Nm] Torque calculated based on application requirements. It must be ≤ Mn2 of the chosen BOX unit. Input power Pn1 [kW] This is the power value of the motor applied to the input shaft and corresponding to a certain input speed n1, a service factor fs=1 and a duty service S1. It is even possibile to calculate the...

stadio Design features STADIO construction is modular and therefore it can be supplied as a separate unit to be mounted on any type of fitted geared motor (PAM). It is not requested any part premounting on the motor shaft. Like all connectable motive motors and gearboxes, STADIO is supplied by Motive with synthetic oil suitable for the whole lifetime. No maintenance requested. Like all connectable gearboxes and motors manufactured by Motive, the whole STADIO range can be mounted in any position with no need of specifications in the order Performance The efficiency at rated speed is 98%. The...
