Failsafe spring-applied motor gearboxes available within 24h

Electrical and automation maintenance and repair company, CP Automation, is now distributing Chiaravalli's failsafe spring-applied motor gearboxes. The devices are suitable for heavy duty applications such as printing and paper converting, as well as applications such as portable lifting equipment when coupled to a battery-operated DC motor.

Available from stock within a week, with optional 24-hour despatch service, the Chiaravalli CH and CHM worm gearboxes could represent a rapid option for industries where downtime can prove expensive.

Tony Young, director of CP Automation, says: "We can fit both AC and DC motors to a CH or CHM gearbox whereas most gearboxes are only suited to AC motors. This allows OEMs and machine builders to expand into new markets where portable equipment may be required. By fitting a 12V, 24V, 48V or 90V DC motor they are ideal for portable battery-operated lifting devices up to five tonnes. Because worm gearing has such a high ratio it will not back-drive. However, because the motor's brake is applied by a spring it is failsafe. Once the equipment you are lifting is in position, the brake safely holds the motor."

The CH gearbox has a motor mounting flange that can separate from the housing which incorporates the oil seal. This avoids the risk of damaging the oil seal in case of replacement of the input flange and allows the O-Ring to be eliminated.

The worm screw has a ZI involute profile providing a gear ratio up to 1:300 as well as better performance at reduced temperature. The gearboxes and motors are painted with RAL 9022 aluminium colour epoxy powder to protect the parts from oxidation and the micro-blowholes that can come about from die casting pressure.

The CHM gearbox has a square shape, making it more versatile for mounting. The machining of the components, carried out using numeric control machines, guarantees precision for restricted tolerances, resulting in a product that will remain reliable over time. The groups are constructed with aluminium casings from sizes 025 to 090, while the sizes 110 and 130 are made from cast iron.

The gears are supplied with at least one filling plug that is also used during testing to check for possible leaks. A connection flange allows two gearboxes to be combined in order to obtain high gearing ratios.
