In any household farm it is much more convenient to process land not manually, but with the help of mechanized units. Even if there are only a few hundred square meters of land, you can use a motor block - a device capable of plowing, burrowing , hilling, etc. This device will save you time and energy.
Motoblock consists of many parts, and each of them has its own purpose. In this article, we will consider one of them - a pulley for a motoblock - and find out what it is.
What is a pulley for a motoblock?
The pulley is an important part of the motoblock with the V-belt drive. It is a small wheel designed to transfer the rotation between the shafts, each shaft being equipped with a pulley. Rotation is transmitted using a special belt.
Pulleys for diesel and gasoline motor blocks are metal and plastic. The former are usually made of cast iron, steel or light metal alloys, they are considered to be more durable and reliable. But plastic products are usually cheaper.
Pulleys differ in the number of so-called brooks. Using the control lever, the belt can be thrown from one stream to another, so that it is possible to adjust the speed of the motoblock. It is very convenient in any agricultural practice. The most popular are two- and three-roller pulleys for motoblocks.
Also, the pulley for the motor block can be either driven or driven, depending on which shaft of the gearbox it belongs to. Different pulley sizes are required for different motor blocks: for example, 19 mm is suitable for the installation of traditional attachments, and 135 mm for heavy motor blocks with an additional drive, which is used as a generator, hydraulic pump, snow blower, rotor braid, etc.
