CARDAN DRIVELINE CATALOGUE
All rotating parts must be shielded to ensure safety. The driveline, tractor, and implement shields must be in place during operation. Equipment should not exceed specified speed and power limits, with a maximum speed of 1000 min-1. Avoid overloading and sudden engagement of the PTO clutch. Ensure the driveline is securely attached and all screws are tight. Avoid loose clothing and ensure the area is well-lit during poor visibility. Use appropriate means for transporting heavy drivelines.
The cardan joint driveline consists of two cardan joints connected by telescoping members. Speed variations caused by the joint angle of the first cardan joint can be corrected by the second joint if the inner yokes are parallel and the joint angles are equal and coplanar, ensuring constant velocity transmission. It is recommended to use drivelines with minimal joint angles to reduce stress.
Telescoping tubes must overlap sufficiently to maintain alignment. Cardan joints should operate with small and equal angles, with a maximum of 45° during short maneuvers. Safety chains should be properly adjusted to allow full movement without excessive slack. Friction clutches can become hot and should be kept clear of flammable materials.
The document discusses the technical aspects of Cardan shaft transmissions, focusing on their specifications, operational procedures, safety standards, and maintenance recommendations.
The Cardan shaft transmission consists of two universal joints connected by telescopic elements. It ensures constant velocity transmission when the internal jaws are parallel, and the working angles are equal and coplanar. This setup ensures the output speed matches the input speed, achieving homokinetic motion. However, telescopic elements are subject to stress from the first joint working diagonally, so it is recommended to use contained working angles.
Tables provide acceptable working angles for the second joint (α2) based on the first joint's angle (α1) and rotational speed. For example, at 750 min-1 with α1 = 12°, α2 should be between 3° and 16°.
The lifespan of the Cardan joint is typically determined by the bearings' life, which depends on torque, speed, and joint angles. A nomogram is used to verify the transmission's sizing based on the required lifespan and operating conditions. For instance, with a size 2 shaft, 200 Nm torque, 540 rpm speed, and 8° joint angle, the estimated life is 2000 hours.
User safety relies on proper use and maintenance of the tractor, machine, and Cardan transmission, along with safety shields. Safety labels and manuals are provided in various languages to meet local requirements. For exports, appropriate labels and manuals must be requested from Binacchi.
Proper lubrication of rotating and sliding parts is crucial for the longevity and reliability of the Cardan joint. Insufficient lubrication or contamination is a common cause of failure. The recommended grease is NLGI #2. Maintenance includes greasing components before use, cleaning, and lubricating at the end of the season.
Agricultural machines are designed for specific load cycles, but overload protection is necessary to prevent damage. Various devices are available to protect against overloads, selected based on the machine's construction and torque diagram. The torque limiter is calibrated based on the average working torque.
The document discusses the use of torque limiters and overrunning clutches in agricultural machinery to manage torque peaks and protect equipment from overloads. These devices are crucial for ensuring the longevity and efficiency of machinery by absorbing excess power and preventing damage.
Torque limiters are designed to interrupt power transmission when torque exceeds a preset value. They are available in various types, including ratchet, shear bolt, and friction torque limiters. Overrunning clutches are used to eliminate reverse torques generated by the inertia of large rotating masses during deceleration or sudden stops.
It is recommended to mount torque limiters and overrunning clutches on the implement side of the driveline. For primary drivelines, these devices should always be installed on the implement side to ensure proper protection. The setting of torque limiters is typically 2 to 3 times the median working torque.
Ratchet torque limiters are suggested for drivelines operating at speeds of 700 min-1 or less. Friction torque limiters are suitable for machines with alternating torque cycles and frequent overloads. Elastic couplers can reduce torque peaks and dampen vibrations.
All rotating parts must be guarded to prevent accidents. The document emphasizes the importance of integrated guarding systems for both the tractor and implement to ensure safety.
The document provides a detailed guide on how to order a drive shaft, including specifications for different types of tubes and safety guards. The PTO drive shaft code consists of 14 positions, detailing the series, size, and additional features.
The document outlines the specifications for joints and double joints, focusing on nominal torque (Mn) and nominal power (Pn). The nominal torque Mn is defined as the torque associated with a 1000-hour lifetime of a joint operating with a joint angle of 5°, rotational velocity of 540 or 1000 min-1, and an 8-hour lubrication frequency. The nominal power Pn corresponds to this nominal torque.
Details are provided for various components such as cross journals, outer yokes, and telescoping members. The document includes specific dimensions and codes for ordering spare parts, with instructions on how to add suffixes to codes for different lengths.
For primary drivelines, any torque limiter or overrunning clutch should be installed on the implement side. All rotating parts must be guarded to ensure safety. Friction clutches can become hot during use, and it is advised to keep the area clear of flammable materials and avoid prolonged slipping.
The document describes different types of torque limiters, including shear bolt torque limiters, ratchet torque limiters, and friction torque limiters. It also mentions overrunning clutches and provides guidelines for their installation and use.
Warnings are included regarding the high temperatures that friction clutches can reach, advising against touching them and ensuring the surrounding area is free from flammable materials to prevent fire risks.
The document outlines various components and specifications related to friction clutches, torque limiters, and elastic couplers. It emphasizes the importance of using original spare parts and ensuring proper installation to maintain safety and functionality.
Instructions are provided for the safe handling and installation of components such as friction clutches and elastic couplers. It is crucial to avoid contact with hot surfaces and ensure that all safety shields are in place before operation.
The document references several standards, including the Machinery Directive (2006/42/CE), UNI EN ISO 4254-1, and ASAE S318.17, which dictate the requirements for safety shields and protective measures. Compliance with these standards is necessary to ensure safe operation.
Manufacturers are advised to apply appropriate labels and provide detailed manuals that include safety instructions and replacement part codes. Regular maintenance checks are recommended to ensure all components are secure and functioning correctly.
The document includes technical specifications for various components, such as dimensions and codes for friction torque limiters and elastic couplers. It also provides guidelines for selecting suitable shields based on application requirements.
