The worm gears made by EP are square and so are considerably versatile for installation. The machining of the components, carried out using numeric control machines, guarantees optimum precision for the limited tolerances, creating a product that may remain reliable as time passes. The organizations are constructed with aluminium casings from sizes 025 to 090, while the sizes 110, 130 and 150 are produced from cast iron. All of the bodies are painted with RAL 9022 aluminium colour to safeguard the parts from ageing and also to give better safety against microblowholes which may be within the aluminium. The gears are supplied with at least one filling connect that’s also used during tests to check for feasible leaks. A connection CHM – WORM GEARED MOTORS AND WORM GEAR UNITS flange enables two gears to become combined to be able to obtain high equipment ratios. Four sizes of CHPC pre-stage gears can be found to set with the gears; these are also constructed in aluminium and so are painted like the worm gears
Gears that are supplied with mounting flanges should be assembled with motors whose shaft and flange tolerances correspond to a “normal course” of quality in order to avoid vibration and forcing of the input bearing. Motors given by Chiaravalli Group S.p.A. guarantee that necessity is fulfilled. For simple consultation, the correspondence of how big is the B5 and B14 electric motor with the sizes of the shaft and the motor connection flange are demonstrated in the following table. Remember that, as the motor connection flanges are separate from the body it is also possible to get a shaft / flange combination that does not correspond to the table, electronic.g. 19/140, thereby offering adaptability for other non-unified models such as the brushless or immediate current types.
