BOX series is available either in IEC version or NEMA version. This catalogue will show the NEMA version only. For IEC version, refer to the specific catalogue 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...

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. The standard worm wheel hub is in spheroidal cast iron, an alloy that offers superior...

IRREVERSIBILITY Some BOX units permit to lock and hold in place a load when electric power switches off. This characteristic, called irreversibility, is inversely proportional to the efficiency and the helix inclination, and directly proportional to the reduction ratio. The efficiency of the toothing profiles is the main factor in effecting successfully the whole efficiency of the wormgear units, and it is on a large extent tied to the helix angle of profiles. In order to get the fittest solution for a certain application, it is necessary to analyse the difference between static and dynamic...

Unless otherwise specified, BOX units sizes 30 up to 90 are supplied with long-life lubrication and they don’t require any maintenance. BOX110, BOX130 and BOX150 are already pre-lubricated as well, with mineral oil VG460. 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...

(for further examples, see AGMA) Rated output torque Mn2 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: Torque demand Mr2 [Nm] Torque calculated based on application requirements. It must be < Mn2 of the chosen BOX unit. Input power Pn1 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 mo-torsize necessary by...
