Abstract

The invention provides a multi-motor integrated driving type electrical-mechanical integration coal cutter cutting head driving assembly. A rocking arm connected with a coal cutter machine body is included, and a motor set is arranged at the front end of the rocking arm, and composed of a plurality of motors distributed in a planet shape; a speed changing box is arranged on one side of the motor set; motor output shafts in the motor set are in synchronous engaging driving with a primary gear in the speed changing box to form a first-stage speed decreasing torque increasing portion; a center rotating shaft of the primary gear and a plurality of planet gears distributed in a planet shape are in engaging transmission so that a second-stage speed decreasing torque increasing portion can be formed; the planet gears and a ratchet gear on the outer ring are in engaging transmission; and a corresponding work portion is arranged on the ratchet gear, and performs coal cutting operation. The multi-motor integrated driving type electrical-mechanical integration coal cutter cutting head driving assembly is high in structural efficiency, capable of saving energy, strong in power, convenient to maintain, capable of reducing the whole machine weight and volume and lowering the comprehensive cost, high in reliability, long in service life, and capable of lowering the maintaining cost and makinga driving system simple.

Description

technical field [0001] The invention relates to the technical field of coal mine intelligent mining, in particular to a driving assembly of a cutting head of a multi-motor integrated electromechanical integrated shearer. Background technique [0002] Since the industrial revolution, coal has always been one of the most important resources in the world. With the rapid development of my country's coal mining industry, the demand for coal has also increased sharply, which has driven the continuous expansion of the scale of market-oriented development. But at the same time, the sharp increase in indicators such as coal production scale, coal output, processing quantity, and processing depth has also put forward more urgent needs for the coal equipment industry. The development of the coal mining equipment industry is facing difficult choices. Fortunately, the good development of coal enterprises over the years has improved the financial situation, greatly enhanced the ability of...
