Operating Principle and Coupling Conditions<\/h3>\n

The Borelli Group 2-3 Mechanical Dog Clutch – 30300 Series<\/strong> is an essential power transmission device in the hydraulic sector, designed for efficient coupling with hydraulic pumps. The variants in this series include unidirectional models (with right-hand or left-hand rotation) and bidirectional models (reversible, identified by two directional arrows). During engagement and disengagement with hydraulic pumps, it is essential that these operations are performed only when the directional control valve is in the unloading position. To maintain system integrity, the maximum rotational speed during these operations must not exceed 1800 rpm for unidirectional versions. For reversible models, the maximum permitted engagement and disengagement speed is reduced to 1000 rpm.<\/p>\n

Mechanical Performance and Operating Parameters<\/h3>\n

Designed for heavy-duty applications, the clutch delivers outstanding mechanical performance. Its structure is engineered to handle a nominal torque of 18.5 daNm and allows a maximum transmissible power of 40 kW. During normal operation, the shaft can reach a maximum speed of 2700 RPM. The mechanical assembly is designed to effectively withstand longitudinal stresses, supporting a maximum axial load of 160 daN. These specifications ensure stable and continuous power transmission even under demanding operating conditions typical of industrial and mobile machinery.<\/p>\n

Lubrication Guidelines and Temperature Limits<\/h3>\n

Maintaining nominal performance and preventing wear of the dog clutch teeth and bearings require strict lubrication management. The system must be lubricated exclusively with SAE 90 oil. The preventive maintenance schedule requires a complete oil change every 12 months of operation. To facilitate fluid inspection and replacement, the clutch housing is equipped with an oil breather plug, an oil level inspection plug, and a 1\/8″ G oil drain screw. The permitted operating temperature range, essential for preserving the integrity of the seals (OR 2031 and OR 109 O-rings, and 45x60x7 \/ 40x52x7 oil seals), extends from a minimum of -10\u00b0C to a maximum of +80\u00b0C.<\/p>\n

Construction Features and Internal Components<\/h3>\n

The robust cast housing contains a high-precision mechanical transmission assembly. The input section features a splined shaft connected to a coupling sleeve (available in reversible, right-hand or left-hand configurations). Engagement is controlled by a fork operated through an external lever (M10 rod equipped with a knob and a spring-loaded ball mechanism). The output shaft transmits power to the pump and is supported by a precision bearing system (codes 6009, 6200 and 3209). The assembly incorporates secure fastening components, including Seeger retaining rings, Benzing retaining rings and Woodruff keys (4×6.5×16), ensuring precise axial alignment. The mounting interface includes dedicated flanges for Group 2 and Group 3 pumps, as well as variants compatible with BOSCH, SAE A and SAE B standards.<\/p>\n
