Abstract

The invention provides a drive breaking tooth roller internally provided with a hydraulic motor, and belongs to the technical field of engineering breaking equipment. A manner of combined drive of a drive motor and a speed reducer is adopted for a traditional breaking tooth roller, as the drive motor is connected with the speed reducer through a coupler, the structure is complex, the occupied space is large, meanwhile a transmission shaft is long, and the transmission efficiency is low. According to the device, the hydraulic motor and a planet-gear reducer are used as drive mechanisms for drive, the mutual engagement transmission energy consumption is low, meanwhile high torque is easy to obtain as the hydraulic motor is used for drive, and the beneficial effects of rapid and impact-free speed change and reversing, stable transmission, the long service life and the like can be achieved. In addition, a breaking roller body is driven through the cooperation of the planet-gear reducer, the structure is compact, the precision is high, the service life is long, the space can be effectively saved, operation is stable, and the power is high.

Description

technical field [0001] The invention belongs to the technical field of engineering crushing equipment, and in particular relates to a crushing gear roller driven by a built-in hydraulic motor. Background technique [0002] Double-toothed roller crushers are widely used in mining, cement, coal, power generation and other industries, and are suitable for medium and coarse crushing of brittle materials below medium hardness. It has the advantages of reliable performance, uniform crushing particle size, low over-crushing rate, low noise, less dust, and low maintenance costs. [0003] The double-toothed roller crusher crushes materials through the extrusion and shearing forces generated by the relative rotation of two crushing toothed rollers. The transmission device of the crushing tooth roller is usually composed of a motor, a reducer, a hydraulic coupling, etc. The motor and the reducer are connected by a hydraulic coupling, and the output shaft of the reducer is connected to...
