Motoblocks that have a power take-off shaft in their functionality, as a rule, in the price of experienced dacities. The presence of such an aggregate makes it possible to apply different instruments in the country. The use of additional equipment will undoubtedly be positively affected by the crop.
Basic functions in BW
First of all, it is necessary to know that the power take-off shaft is a device for transmitting the engine energy to the moving elements of the tools or mechanisms that work with a motoblock. In the machines, in most cases, the drive mechanism of agricorudia is connected to the power take-off shaft using a slotted sleeve. This method of compound significantly increases the reliability of the mechanisms and increases their service life.
Most of the entire range of aggregates is equipped with a shaft, which is installed in the back of the motoblock. But sometimes there are agricultural machines equipped with in the face located on the front side of the aggregate.
List the tasks that the power takes place.
- Running and functioning of the mechanisms of mounted gun. It is worth noting that equipment nodes can be powered both directly and with belt gears, gearboxes or cardan shafts. From the connection principle changes the degree of load on the mechanism.
- Sometimes the power take-off shaft can be useful for the operation of hydraulic trailer systems. At the same time, the shaft acts directly to the hydraulic pump. But for such functions, I needed infrequently, because the summer houses are very rarely used tools with hydraulic systems.
The ability to implement the tasks described has made motoblocks with a power selection shaft very popular among the owners of large summer cottages.
Power selection shafts are divided into classes depending on their principle of operation. Consider this nuance, then All mechanisms can be divided into several types.
- Shafts operating directly from the engine of the motoblock, are called dependent. In the event that there is no coupling connections with the engine, then it ceases to rotate.
- In an independent embodiment, the power take-off shaft works in a more gentle mode due to the uniform load distribution. This type of drive makes it possible to use the mechanism when the clutch is turned off.
- If the non-stop work is provided by the rotation of the wheels, then such a shaft is called synchronous.
- Asynchronous shafts, according to the principle of operation, are the opposite of the mechanism of the previous class. Nodes of this type are usually designed for guns, which should work with stops and at low speeds.
This kind of classes division will allow the owner to choose a motoblock with a suitable type. Although in the required case, the shaft of another type can be purchased separately and install it independently.
How to choose a motoblock?
Before purchasing an aggregate, it is necessary to focus on the complex of operations that the motoblock will have to perform. Do not buy the most expensive modifications of units that have a complete set of functions in their arsenal. Not every model can cope with the task.
For example, in large areas having a tight soil composition, the optimal option will be the purchase of a heavy unit, while there will be a slight-class motoblock on a small cottage.
And also when choosing, it is necessary to decide with the type of fuel on which agricultural machine will work. The aggregates with a gasoline engine work quieter, have low weight, convenient to maintain. Diesel motoblocks are more noisy, but take up their high power. The minus of the diesel is his high price.
It must be borne in mind that Additional attachments can often be represented by another manufacturer. In this case, to connect the gun to the acquired motoblock The adapter will be required. This can lead to a malfunction of an aggregate or problems in performing work.
On the market today the range of motoblocks is quite diverse. The models of such companies like Husqvarna, Profi, Hyundai enjoy in great demand. In our country and the near abroad, such cars are represented as “Belarus”, “Neva”, “Salyut-100”. Of course, it is not worth discounting and Chinese firms Forte, Wiema, because their products are also pretty in demand.
If you compare foreign models with domestic counterparts, you can see that they do not always have the cost is justified with reliability and ease of operation. Besides Export models will require expensive consumables and the presence of experienced specialists for maintenance. Both are very difficult to find.
Domestic firms are focused on ease of use, low cost. The decisive factor is the ability to repair a motoblock on its own forces.
In order to get some idea of motoblocks with a power take-off shaft, you must read the characteristics and features of some models in more detail.
NEVE MB compact C-6,0
The motoblock of this model is considered a real find for adherents of professional equipment. The unit has great functionality, despite its compact sizes. In almost the entire range of mounted guns from a plow and ending with a snow blower rotor.
Thanks to the design of the gearbox, showing powerful traction characteristics, the motoblock is capable of using reduced transmission, produce plowing very hard soil. In addition, the motoblock can be used to transport goods weighing up to 500 kg.
Specifications Manufacturer Indicates the following:
