Product catalog summary
Company Profile
Comer Industries is a leading provider of mechatronic solutions and integrated systems for power transmission, serving major agricultural and industrial machinery manufacturers globally. The company operates five plants in Italy, with additional facilities in China and India. Their product offerings include a wide range of standard and customized power transmissions such as gearboxes, driveshafts, and planetary gearboxes, focusing on agricultural and industrial applications. Products include driveshafts and constant velocity joints for power transmission ranging from 12 KW to 144 KW, along with safety devices like clutches and torque limiters.
Cardan Joint Theory
The PTO driveshaft for agricultural applications features two cardan joints and a telescopic coupling. The cardan joint transmits motion between two tilted axles, with speed differences influenced by the articulation angle. The transmission ratio varies with articulation and rotation angles, affecting motion regularity and potentially causing vibrations and noise.
Kinematic Characteristics
The PTO driveshaft's two cardan joints can either cancel or combine irregularities. When articulation angles are equal, transmission is uniform, eliminating undesirable effects. Otherwise, irregularities persist, which can be evaluated using a specific graph.
CVJ Joint
The Constant Velocity Joint (CVJ) ensures equal speed between input and output yokes, eliminating rotation irregularities. In driveshafts with a CVJ and a standard joint, irregularity is due to the standard joint, which should operate at small angles. For high angles, two CVJ joints are recommended. The CVJ joint can handle high angles briefly, with construction quality ensuring reduced stress and wear.
Power and Torque Ratings
Detailed power and torque ratings for various types of driveshafts at different RPMs are provided, highlighting maximum dynamic torque and conditions for continuous operation.
Calculation of Cross and Bearing Kit Life
Examples and charts are provided to calculate the life of cross and bearing kits for different series, considering factors like torque, RPM, and articulation angles.
Specifications and Part Codes
The document provides detailed specifications and part codes for various types of yokes and profiles used in mechanical assemblies, focusing on inner joints, collar yokes, and double yokes. It includes measurements in both metric and imperial units, along with specific codes for each part.
Key Data from Tables
Measurements are provided in both millimeters and inches, ensuring compatibility with various mechanical systems. Each component is assigned a specific code for easy ordering and replacement. Certain profiles are treated with NITREG or coated with RILSAN for enhanced durability and performance.
Critical Information
The document emphasizes the importance of matching part codes and measurements to ensure proper assembly and function. Treatments like NITREG and RILSAN are highlighted as key factors in extending the lifespan of components.
Procedures and Standards
Heat treatment and decals for CE, USA, and Canada standards are available upon request. Safety devices must be installed on the implement side of the PTO driveshaft.
Safety Precautions
Do not use the transmission as a support or footboard. Ensure the engine is turned off, keys are removed, and all rotating parts have stopped before approaching machinery or performing maintenance. Clutches can become very hot; do not touch them. Keep the area clean to prevent fire risks.
Machine Directive Compliance
The Machine Directive (98/37/CEE) requires that the power take-off on machinery is equipped with a safety shroud that allows for driveshaft assembly and articulation, ensuring at least a 50 mm overlap with the driveshaft safety guard. Comer Industries provides shrouds compliant with international standards, accompanied by a CE instruction sheet.
Technical Specifications
The document includes detailed dimensions for splined profiles and conversion tables for various units of measurement, including length, weight, force, torque, and power.
Additional Information
Comer Industries provides updated information about their sales network and product ranges on their website. They disclaim liability for the completeness and accuracy of the information and note that it can be revised without notice.

TEORIA DEL GIUNTO CARDANICO CARDAN JOINT THEORY 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). The PTO driveshaft for agricultural applications consists of two cardan joints...

CARATTERISTICHE CINEMATICHE KINEMATIC CHARACTERISTICS L’albero cardanico 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 valutata con il grafico della pagina seguente (Fig.5). The PTO...

Generally permissible values, depending on the masses involved. L'irregolarita ”i” del moto dipende dall' inclinazio-ne dei due snodi cardanici e dalla differenza fra le angolazioni dei due snodi (vedi es.: a parita di differenza angolare l'irregolarita e maggiore se le inclinazioni dei singoli snodi sono maggiori).

GIUNTO OMOCINETICO CVJ JOINT Il giunto omocinetico (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 omocinetico 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 di elevati angoli di lavoro alle due estremità dell'albero è necessario...
