The worm gears made by EP are square and so are considerably versatile for mounting. The machining of the components, carried out using numeric control machines, guarantees maximum precision for the restricted tolerances, making a product that will 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 to give better safety against microblowholes which may be present in the aluminium. The gears are given at least one filling connect that’s also used during tests to check for feasible leaks. A connection flange allows two gears to end up being combined in order to obtain high equipment ratios. Four sizes of CHPC pre-stage gears are CHM – WORM GEARED MOTORS AND WORM GEAR UNITS available to pair with the gears; these are also built in aluminium and are painted just like the worm gears
Gears that are given mounting flanges should be assembled with motors whose shaft and flange tolerances match a “normal course” of quality 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 the size of the B5 and B14 motor with the sizes of the shaft and the electric motor connection flange are proven in the next table. Understand that, as the motor connection flanges are separate from the body additionally it is possible to possess a shaft / flange combination that will not correspond to the table, electronic.g. 19/140, thereby offering adaptability for additional non-unified models like the brushless or immediate current types.
