Product catalog summary
Axial Loads
The document specifies that the axial load (Fa2) is 20% of the radial load (Fr2), applicable for both tensile and compressive stress, and included in the catalogue radial load figure.
Geared Motors and Gearboxes
Specifications for geared motors and gearboxes with two and three gear sets are detailed. Power ranges from 0.09 kW to 22 kW, with output speeds from 250 rpm to 2.5 rpm. Gearboxes come in various configurations, with output torque from 120 Nm to 3400 Nm and reduction ratios from 6.3:1 to 710:1.
Thermal Power
The rated power (P1) is applicable at the gearbox input under continuous operation with specific environmental conditions. Thermal power (Pt1) may limit rated power based on cooling system, input speed, ambient temperature, and service factor.
Technical Data Tables
Extensive tables provide specifications for various gearbox models, including output speed, torque, input power, and radial forces, aiding in selecting the appropriate model.
Weight and Oil Capacity
Information on weight and oil capacity for different gearbox models is provided, essential for installation and maintenance planning.
Speed Reducer Selection
Guidelines for selecting the appropriate speed reducer are provided, with specific models and technical specifications listed.
Machine Shaft Dimensions
Detailed dimensions for machine shafts suitable for various hollow output shafts are provided, including diameter, length, and thread specifications.
Assembly and Disassembly Procedures
Procedures for mounting and dismounting machine shafts are outlined, emphasizing cleaning, oil application, and screw tightening. Disassembly involves gradual screw loosening.
Spline Shafts
Spline shafts, with teeth meshing with grooves, offer higher torque and longer fatigue life compared to key/keyway connections.
Accessory Positioning
Accessory positions are defined as RH and LH, referring to specific mounting positions, with orders pending until the side is defined.
Gearbox Components
Two-stage and three-stage gearboxes are described, detailing components like motor flanges and input/output rotation directions.
Electric Motor Standards
Standards include insulation classes, voltage, frequency, and temperature factors, specifying conditions for normal and heavy-duty operations.
ATEX Directive Compliance
The European Directive 94/9/EC-ATEX is addressed, covering gearboxes for explosive environments. VARVEL-ATEX gearboxes ensure safety and compliance, categorized by exposure levels and protection indices like IP66.
ATEX Directive Code Breakdown
  • Group Utilization: I (Mining), II (Surface industries)
  • Category: 1 (Continuous exposure), 2 (Occasional exposure), 3 (Unlikely exposure)
  • Presence Indicators: G (Gas), D (Dust)
  • Safety Indications: c (Construction safety), k (Immersion safety)
  • Protection Coding (IP66): Dust tight, protection against powerful water jets
  • Temperature Indicators: Tmax (Maximum surface temperature), Tamb (Maximum ambient temperature)
VARVEL-ATEX Gearboxes
Not certified for shaded areas, conform to Group II, Category 2 or 3 for hazardous zones with gas and dust, marked as II 2 GD ck IP66 Tmax=135°C.
Operation and Maintenance Instructions
Ensure correct selection and mounting stability, stop immediately if defects occur, use synthetic oil, handle with appropriate lifting points, protect components during repainting and storage, and dispose of components according to ISO 14001.

RN series-4

Descrizione - Description - Beschreibung La serie dei riduttori RN è concepita secondo le norme di progettazione ISO con l’ausilio di analisi strutturale per verifica della deformata e dello stress. La robusta struttura non subisce deformazioni significative sotto effetto della coppia di funzionamento e dei carichi esterni con positivi risultati sulle superfici di tenuta. I riduttori delle serie RN sono costruiti in alluminio pressofuso per le prime 3 grandezze ed in ghisa per le rimanenti. La versione pendolare permette la conversione in forma flangiata B5 applicando semplicemente una delle...
