Product catalog summary

Specifications:
The document details the specifications of various gearboxes, focusing on rated output torque and power rating. Gearboxes are available in seven sizes with torque ranging from 20 N.m to 1500 N.m and power from 0.06 to 9 kW. Reduction ratios range from 5.2 to 2630, with efficiency between 55% and 88%.

Materials and Construction:
Gearboxes are made from materials like aluminium and cast iron for housing, bronze and steel for the wheel and worm, and steel for shafts. The design enhances mechanical strength and heat dissipation, with reinforced ribbing to reduce vibrations and noise. Various mounting configurations are available.

Lubrication and Seals:
Gearboxes use oil lubrication per ISO 6743/6, with drain, level, and vent plugs. Nitrile lip seals provide dust protection, and sealing surfaces are ground for improved performance.

Mounting and Motors:
Multiple mounting options are offered, including input shaft gearboxes and geared motors with IEC motors. Standard motors come in various voltage configurations, with brake motors also available.

Selection and Verification Procedures:
The document outlines procedures for selecting an input shaft gearbox, including calculating duty factor, reduction ratio, and equivalent torque or power. It stresses verifying maximum permissible torque and thermal power to ensure suitability for applications.

Example of Selection:
An example for a belt conveyor application is provided, detailing the calculation of duty factor, reduction ratio, and output torque, demonstrating the selection and verification process.

Overview:
The document provides detailed specifications and selection guidelines for IMfinity® Multibloc geared motors with worm and wheel configurations, covering models, dimensions, operating positions, and selection criteria for various applications.

Selection Procedure:
1. Determine application requirements, including input power, speeds, operating time, and starts per hour.
2. Select motor type based on application needs.
3. Choose a geared motor with a suitable duty factor and output speed.
4. Verify maximum permissible torque.
5. Check rated thermal power adequacy.
6. Verify permissible radial and axial forces on the output shaft.
7. Select appropriate operating positions and accessories.
8. Follow commissioning and storage guidelines.

Example Selection:

Geared motors with worm and wheel - IMfinity ® Multibloc Construction Description Multibloc worm and wheel geared motors are used to adapt the speed of the electric motor to that of the driven machine. Therefore, they are determined by the motor power (P) expressed in kilowatts (kW) and the output rotation speed of the gearbox (Ns) in revolutions per minute (min-1). The main characteristic of the gearboxes is the rated output torque (Mns) expressed in Newton-metres (N.m): Mns = P x 9550 x efficiency Ns A range of seven sizes: 41, 31, 22, 23, 24, 25, 26. Rated output torque: 20 N.m to 1500 Nm. Power...
