The A-613 gearbox with electric actuator ready for integration with the ISOBUS system

The A-613 parallel axis unit, fitted for gear engaged position sensors and equipped with electric actuator for gear change, has the following characteristics:

·      low-noise helical gear transmission featuring gears with high contact ratio;

·      internal pre-load mechanism enabling gear change and automatic re-engagement;

·      electric actuator with two or three positions (for neutral);

·      integrated fitting for pump coupling.

The unit is available in the gear ratios 1:1/1.8:1 and 1:1/1.5:1, with 180 HP at 540 rpm and it is suitable for feed mixers with two or three augers, with capacities starting from 30 m³.

The A-613 transmission is part of the Mix@tractor project developed by IDEAgri, a network of companies (including Comer Industries) that manufacture integrated systems pursuant to the ISOBUS Standard (www.ideagri.net). IDEAgri will be exhibiting at the AEF (Agricultural Industry Electronics Foundation) showcase in the Eima Quadriportico area.

This system uses an innovative hardware/software platform for coordinated management of the tractor and implement functions during the Unifeed mixing stages.

Thanks to the electrically actuated gear change system and the implementation of the ISOBUS torque sensor, the IDEAgri solution allows for monitoring power absorption, automating gear change stages based on the progress of the mixing process. This way, an optimized cycle in terms offuel consumptionemissionsnoise pollutionsafety and duration of the operations can be established without the operator needing specialized knowledge or skills.

New PGA-2100 series planetary gearboxes for vertical feed mixers

Comer Industries has expanded its PGA line of planetary drives, introducing the new 2100 series for auger activation on trailed feed mixers, with 2,100 daNm of continuous torque and maximum torque of 4,700 daNm.

This compacthigh performance model was developed to offer significantly greater load capacity and torque in the same dimensions as the 1600 series, combined with increased reliability of the transmission components and greater resistance under overload conditions.

These results were achieved by combining design and technology solutions that had already been developed and implemented by Comer Industries on wind-turbine drives, with specific solutions for feed mixer applications.

The main design and process innovation features are:

·      four-planet planetary stage with support bearings and pivoting carrier pins;

·      steel planetary carrier with a specific vertical configuration (patent pending);

·      higher precision and capacity gearing made possible by the special shot peening and finish machining on the teeth.

System for self-propelled feed mixers with vertical augers

For the sector of forage processing and distributing machines, Comer Industries will be showing a solution for self-propelled feed mixers consisting of S-238 differential axle and PGA-2503 VM planetary drive with hydraulic control. 

The S-238 12-tonnes axle, featured by compact dimensions, is available in fixed and steering versions.

This product caters to the growing requirements of manufacturers in terms of boosted efficiency and provides the following benefits:

·      better performance, even with the same total weight, thanks to increased dynamic load;

·      greater compactness, for easier installation of the axle inside the machine.

This is a flexible solution, in line with customers’ requests for a design aimed at improving vehicle’s configuration and increased productivity.

The transmission system is completed by planetary gears for transmitting the vertical drive to the augers: the PGA -2503 VM, with compact hydraulic connection, can be combined with different types of hydraulic motor. A small size version - the PGA-1603 VM- is also available.

Complete side transmission for grain headers’ cutter bars

For grain headers, Comer Industries will be displaying the complete side transmission for cutter bars, consisting of the T-312 unit, now produced in aluminum to obtain a significant weight decrease, the new “E-torque” driveshaft, and the wobble box OS-780 for blade operation.

The driveshaft is equipped with a rubber element device that damps vibrations and alternative loads coming from the grain header cutting system. 

The wobble box OS-780 provides for the handling of the cutter bars with alternate linear motion, universally used for combine harvesters’ grain headers. The transmission transforms, via eccentric system, the input rotary motion into linear motion through the connection to the cutter bar by means of an arm and of a spherical knot.

VP driveshaft professional range

Comer Industries will be exhibiting the professional range of VP Series driveshafts, which features new EC type-approved accident prevention protectionhigh performances and easy maintenance.

This professional product line is versatile and available in many advanced solutions: transmissions are characterized by boosted efficiency and attention to the environment, thanks to reduced maintenance and less use of lubricants.

The VP range was created to meet the demands of high-performance, intensive use, typical of the contractor sector. To cover all needs of users, nine product sizes in the standard version and four sizes in the constant velocity version are available.

Maintenance is facilitated, thanks to the alignment of the access holes to the greasing points: lubrication can be performed without disassembling the driveshaft from the PTO. Maintenance intervals have been extended and, depending on the use conditions, can reach up to 250 hours.

New guard locking system with single chain guarantees quick and safety and offers the possibility of moving the bellows backwards, thus facilitating the assembly on the PTO of the tractor.

The version with constant velocity joint VP7 CVJ has a new guard that allows the PTO to operate as far as 80° working angles, without interfering with the tractor’ master shield. The new CVJ system, thanks to the floating plates, provides excellent sealing of the lubricating grease, thereby reducing maintenance intervals.

Driveshaft safety devices, such as limiters and easy connection devices are also on display. They are designed and manufactured according toquality procedures in compliance with international standards. All Comer Industries’ driveshafts protect the operator from any hazards associated with agricultural machine applications and provide complete protection thanks to counter-cones and to extended guards.
