ISM/BSM

Product catalog summary

Overview: The document provides technical specifications and installation guidelines for ISM (Input Shaft Modules) and BSM (Backstop Modules) used with VARVEL gearboxes. These modules can be fitted to most VARVEL 'S' type gearboxes without input flange and 'G' type gearboxes with flexible coupling.

Specifications: ISM and BSM modules are compatible with various motor flanges, power and torque ratings, and reduction ratios as detailed in the RS-RT, RD, and RN-RO-RV catalogues. The ISM modules handle overhung loads as specified in the RS-RT catalogue.

Design and Features: The ISM input shaft is supported by two 2RS shielded ball bearings, eliminating the need for additional lubrication. A half coupling is provided for direct connection to VARVEL gearboxes. The BSM module is available in two versions: one with a solid input shaft, ball bearing, and backstop bearing, and another with an IEC or NEMA flange and backstop bearing only.

Installation: Both ISM and BSM modules can be installed quickly using a simple spanner. The BSM module can be fitted to any VARVEL gearbox with a 'G' type flexible input coupling.

Standards and Certifications: The document references compliance with UNI EN ISO 9001:2015, UNI EN ISO 14001:2015, and BS OHSAS 18001:2007 standards.

Contact Information: VARVEL SpA is located in Valsamoggia, Italy, with contact details provided for further inquiries.

Data Summary: A table is included showing compatibility of ISM and BSM modules with various gearbox models and stages, indicating specific configurations for different sizes and types.

ISM - Input shaft module ISM - Modulo entrata albero sporgente The input shaft is supported by two 2RS shielded ball bearings and does not therefore require additional lubrication. A half coupling is provided for direct coupling to the VARVEL gearbox. L’albero di entrata è supportato da due cuscinetti a sfere schermati del tipo 2RS e pertanto non necessita di alcuna lubrificazione. E’ fornito in uscita del semi-giunto per accoppiamento ai riduttori VARVEL corrispondenti. BSM - Input backstop module The BSM backstop module is available in two versions: one with solid input shaft, ball bearing and backstop bearing and one with IEC or NEMA flange and backstop bearing only. The module can be fitted to any VARVEL gearbox with a “G” type flexible input coupling. BSM - Modulo entrata anti-retro Costruito in due versioni, albero sporgente con cuscinetto a sfere e cuscinetto anti-ritorno e flangia IEC o NEMA con solo anti-retro, permette il montaggio ai riduttori VARVEL in versione entrata con
