Balancing Machine for Drive Shafts
Series RBRQ

Range of application
Measurement and correction of unbalance in single and multi-piece drive shafts of passenger vehicles, light and heavy duty commercial vehicles.

Balancing and correction capacity for manufacturing, testing and inspection at vehicle manufacturers and component suppliers plants.

High speed measurement of unbalance close to or at operating speed.

Unbalance correction through spot or projection welding using medium frequency techniques, of preformed correction weights. For correction by drilling into the articulated heads or flanges, a traversing drill unit can be supplied.

Design
Machine design is ideally suited for balancing vehicle drive shafts. Arrangement of the machine components takes ergonomic requirements into consideration. Vertical arrangement of the correction units (welding or drill unit).

Welded machine base, specially designed for high speed measurement. Isotropically supported bearing pedestals with heavy duty, precision spindles. Variable speed AC main spindle motor is standard equipment. 

Bearing pedestals with hard-bearing suspension system and precision spindle. Asymmetric arrangement of the spindle axis for ergonomic loading and unloading of the drive shaft. Tooling adapters with spring actuating clamping device (pneumatic unclamping) can be supplied.

Patented single-station quadruple welding unit. Longitudinal and radial drill units with chip extractor are available (as options) for correction by drilling into the knuckles or flanges. Heavy duty safety devices that are horizontally adjustable and easy to dismount, to secure the drive shaft during rotation. These allow adjustment of the support pedestals to accommodate very short shafts. Rollers built into the safety devices as loading aids are automatically retracted before the measuring run.

Standard protective safety guarding in modular elements with laminated plates for burst and noise protection in high-density, noise absorbent laminate type construction. Quick acting pneumatic actuation of the large horizontally opening doors.

Microprocessor-controlled measurement equipment with monitor for optimal calculation of the correction weights and direct display. Digital measurement technique with high frequency-selectivity. Electrical compensation for residual tooling unbalance and clamping eccentricity. Other special features: Large display, operator prompting, diagnostic program, fault display, statistics program and printer interface. Measurement equipment prepared for remote diagnosis via interface.
