Product catalog summary
Introduction
This guide offers detailed instructions for selecting the appropriate bell-housing and drive coupling for IEC electric motors sized 63 to 225, covering specifications, installation procedures, and noise reduction strategies.

Specifications
The document specifies dimensions and codes for bell-housings and couplings, such as the LMC250 and LMS250 models, which require specific drilling codes like code 060 for a spigot hole of 82.55 mm and a PCD of 106.4 mm.

Procedures
It provides detailed steps for calculating bell-housing lengths and selecting coupling components, emphasizing that the bell-housing length must meet or exceed the calculated length (e.g., 135.5 mm). Guidance is also given for choosing the correct half-coupling length based on the bell-housing type.

Noise Reduction
The document explains noise theory and the role of bell-housings in noise transmission, recommending low noise bell-housings to reduce vibrations and noise emissions. Proper installation is crucial, with guidelines for mounting on oil tank lids and machines.

Installation Recommendations
Recommendations include using rigid suction pipes with resilient bulkhead flanges, flexible pressure pipelines, and anti-vibration devices to prevent vibration propagation.

Technical Data
Bell-housings are made from pressure die-cast aluminum with galvanized steel center rings and special paper gaskets, compatible with various fluids and operational between -30°C and +80°C.

Conclusion
For optimal performance, the document advises integrating the motor-and-pump unit into the hydraulic system without rigid connections, ensuring proper installation and noise reduction, and provides recommended tightening torques for motor/pump fixing on the bell-housing.

GENERAL INFORMATION Noise is a particularly pervasive problem so much so that there have been statutory regulations in place now for some years, designed to limit harmful occupational exposure. Many of the machines used in industry today are equipped with oil-hydraulic systems, which happen to be a major source of noise. THEORY AND DEFINITION OF NOISE From a health and hygiene standpoint, noise can be defined as an unpleasant and undesirable sound, or an unpleasant and annoying or intolerable auditory sensation (noise being any sound phenomena that may be accompanied by sensations of disturbance...

ASSEMBLY OF MOTOR AND PUMP UNIT Low noise bell-housing will help to attenuate the transmission of vibrations and the emission of noise generated by the system. Self-evidently, however, the mere adoption of a low noise bell-housing will achieve little unless the motor and pump are correctly installed on the machine or on the tank of the hydraulic power unit. Should be followed in order to achieve best possible results and correct installation: ® MOTOR AND PUMP UNIT MOUNTED HORIZONTALLY ON OIL TANK LID - The suction pipe attached to the pump must be rigid and fitted using a resilient bulkhead flange...
