High-load-bearing compact type rotary support gearbox

Abstract

The invention relates to a high-load-bearing compact type rotary support gearbox. The gearbox comprises a power input device and a power output device, the power input device comprises a motor, a speed reducer and a worm, the motor is connected with one end of the speed reducer, the other end of the speed reducer is connected with the worm, and conical roller bearings are installed at the two ends of the worm; the power output device comprises a shell, a worm gear and a bearing, the power input device is installed in a shaft hole of the shell, the worm gear is meshed with the worm in the power input device, and bearing inner rolling ways are arranged on the two sides of the circumference of the worm gear; the bearing is matched with the bearing inner rolling ways on the two sides of the worm gear, positioning devices are arranged on the two sides of the bearing, and sealing rings are arranged on the positioning devices; the bearing is not provided with an inner ring. According to the gearbox, a novel rotary driving structure is achieved, the installation structure of a rotary support is optimized, the reliability of the rotary support gearbox is improved, and the manufacturing cost of the rotary support gearbox is reduced.

Description

technical field [0001] The invention is applicable to a photothermal tower type slewing support driving and tracking system, and in particular relates to a high-load compact slewing support gearbox. Background technique [0002] Due to global warming caused by environmental pollution, countries have begun to vigorously develop renewable clean energy. Photothermal, as one of the renewable clean energy sources, is inexhaustible and can alleviate the global greenhouse effect. One of the ideal energy sources, it occupies an important position in the medium and long-term energy strategies of various countries. [0003] In recent years, my country's solar thermal power generation has developed rapidly, and the total installed capacity of solar thermal power generation continues to rise. The scale of solar thermal installed capacity announced by my country has exploded, and the solar thermal power generation industry has shown a booming scene of prosperity. [0004] The tracking s...
