Gearboxes for motor-drills

At the moment, in the world of technologies and equipment for construction, there are an endless number of different names and models. Today we will talk about such a device as a motor-drill. What it is, and how to use it, what types there are, as well as how to choose a gearbox for it, you will learn by reading this article.

First, you need to figure out what a motor-drill is. It is a portable, man-operated earth-borehole drilling rig with handles. It is used in work to strengthen the foundation, when installing fences, geological and other works.

This mechanism is a mechanical product equipped with a gasoline engine. Its package includes:

• engine;
• auger (drill);
• frame.

But we will talk about gearboxes, which, in fact, are the heart of our today's device. The gearbox is the component of the engine that generates torque and drives all gears and teeth.

Gasoline powered devices run at high revs. In order to transmit sufficient power, it is necessary that they be equipped with devices that reduce the speed.

Each gearbox has its own peculiarity, due to which it is used in various fields. Most often they are classified according to the method of transmission of rotating mechanisms, it is on this that the efficiency of the device depends. The main types of gearboxes include devices:

• on a hydraulic basis;
• based on the worm system;
• based on coaxial cylinders.

We can say about the hydraulic system of the gearbox that it is very wear-resistant and durable, unlike others. Inexperienced experts find that such devices are very expensive to maintain and complex. But this is not so: it is enough just once a year or a season to change the oil and filters in the hydraulic system.

The second type of gearbox is special due to its conversion of motor torque into angular speeds using worm gear transmissions. The advantages of such a device are its quiet operation, a high degree of smoothness of the tool during the drilling process.

But there are also disadvantages, one of them is the unreliable gear wheels of the final drives, which are made of bronze.

The third type of mechanical device is the most demanded in the industry. Spur gearboxes are inexpensive and have been used for a very long time. Their advantage is that, when assembled, they can work in any climatic conditions, they are very light, they can be simply mounted or dismantled.

Besides, gas drill gearboxes are straight and lateral. It depends on the motor connection.

When using any mechanical device, it is necessary to follow the operating rules. In the kit with each equipment there is an instruction that describes the points of safe and correct use of the motor-drill.

Here are some aspects of using this device:

1. the motor-drill can only be used by adults;
2. make sure that there is a sufficient level of oil and grease in the device before use;
3. it is necessary to lubricate the elements of the device with a quality product;
4. it is necessary to fill in high quality gasoline so that the motor drill works smoothly and properly;
5. refuel the tool away from fire, while turning off the engine;
6. it is necessary to use oil intended for two-stroke engines;
7. it is necessary to move the motor drill with the engine off;
8. work with the tool in a well-ventilated room;
9. spare parts must be bought in specialized stores that have special certificates;
10. oil and other parts must be changed at service centers;
11. keep the motor drill in an upright position in a room where there is no humidity, and with an empty fuel tank;
12. when working with a motor drill, you must wear non-slip safety boots, gloves, goggles and a helmet.
