Cardan Joint Theory
The PTO drive shaft for agricultural applications consists of two cardan joints and a telescopic coupling. The cardan joint transmits motion between two tilted axles, with speed variations depending on the articulation angle, leading to potential motion irregularities.
Kinematic Characteristics
Irregularities in standard PTO drive shafts can be canceled or combined. Uniform transmission occurs when articulation angles are equal, eliminating undesirable effects.
Constant Velocity Joint (CvJ)
The CvJ is a double joint with a centering system that ensures equal articulation angle distribution, eliminating rotation irregularities. For high work angles, two CvJ joints are required.
Technical Specifications
The document includes a table detailing power, torque, and rotational speed for different drive shafts, highlighting performance capabilities at 540 and 1000 r.p.m.
Specifications
Details for components related to driveshafts, including joints, yokes, flanges, and bolt sets, with measurements in metric and imperial units.
Procedures
Instructions for ordering joints with specific yoke configurations, emphasizing the need to specify yoke references.
Standards and Recommendations
Recommended tightening torque values for bolts of different sizes to ensure proper assembly and safety.
Series and Types
Descriptions of different series of joints for PTO drive shafts, including specifications for outer and inner joints.
Torque Limiter Functionality
The torque limiter activates when operating torque exceeds a preset value, transmitting power in reduced pulses. Disconnecting the PTO is recommended to prevent wear and overheating.
Device Specifications
Detailed specifications for various models of torque limiters and overrunning clutches, crucial for selecting the appropriate device for specific applications.
Operational Recommendations
The device transmits motion in a single direction when the tractor drives the implement, beneficial for machinery with high rotational inertia.
Closed Disc Clutch Torque Limiter Overview
Specifications and operational guidelines for closed disc clutch torque limiters, designed to protect machinery by limiting torque transmission during overload conditions.
Safety Precautions
Friction clutches can reach high temperatures; it is crucial to avoid contact and keep the area free of flammable materials.
Components and Parts List
Lists various components and kits associated with torque limiters and overrunning clutches, providing a comprehensive guide for assembly and maintenance.
Half-Opened Disc Clutch Torque Limiter Overview
Technical specifications and operational details for a half-opened disc clutch torque limiter with an overrunning clutch, designed to protect machinery by managing torque and preventing overloads.
Additional Features
The device can be configured for anti-clockwise rotation on request, combining functionalities of individual devices for efficient mounting.

TEORIA DEL GIUNTO CARDANICO CARDAN JOINT THEORY THEORIE DU JOINT DE CARDAN GELENKWELLENTHEORIE L’albero cardanico per uso agricolo è costituito da due giunti cardanici e da un accoppiamento telescopico. Il giunto cardanico, composto da due forcelle e una crociera, è l’elemento che consente di trasmettere il moto fra due assi inclinati. La costruzione del giunto cardanico è tale che durante la rotazione la velocità dell’albero in uscita non è sempre uguale a quella dell’albero in ingresso e questa differenza di velocità dipende dall’angolo di snodo del giunto (Fig1). Il rapporto di trasmissione...

CARATTERISTICHE CINEMATICHE KINEMATIC CHARACTERISTICS CARACTERISTIQUES CINEMATIQUES KINEMATISCHE EIGENSCHAFTEN L’albero cardanico standard è composto da due giunti cardanici. Le irregolarità dei singoli giunti possono quindi eliminarsi o comporsi reciprocamente. Quando gli angoli di snodo dei due giunti sono uguali, vedi disposizione W o disposizione Z (Fig.3), la trasmissione è omocinetica, cioè la velocità della forcella in uscita è sempre uguale a quella in ingresso, eliminando quindi gli effetti indesiderati. In tutte le altre angolazioni (Fig.4) rimane sempre una irregolarità che può essere...

GIUNTO OMOCINETICO CvJ CONSTANT VELOCITY JOINT CvJ JOINT HOMOCINETIQUE CvJ WEITWINKELGELENKWELLE CvJ Il giunto omocinetico CvJ (giunto a velocità costante) è un doppio snodo con un sistema di centraggio che garantisce una eguale ripartizione dell'angolo di snodo fra le due forcelle (disposizione a W). La velocità della forcella in uscita è sempre uguale a quella in ingresso e non vi sono irregolarità di rotazione. In un albero cardanico con giunto CvJ e un giunto standard (Fig.6), l'irregolarità totale è dovuta al solo giunto standard, che perciò deve lavorare a piccoli angoli di snodo. Nel caso...
