Double-base gear type ventilation rotary table structure

Abstract

The invention discloses a double-base gear type ventilation rotary table structure which comprises a ventilation hole; the ventilation hole is provided with a bottom ring; the bottom ring is fixedly connected with a mounting plate arranged at the ventilation hole; the bottom ring is provided with a central ring; the central ring is provided with a top ring; steel balls in annular distribution arearranged between the bottom ring and the central ring and between the top ring and the central ring; the bottom ring, the top ring and the central ring are all annular components with central openings; the outer ring of the central ring is in a gear shape; the mounting plate is further provided with a drive gear; and the drive gear is engaged with the outer ring of the central ring. The double-base gear type ventilation rotary table structure has the beneficial effects that cold air emission positions are not single, and the central ring can bear thrust and also tensile force, can also bear irregular force such as the thrust at one end of the ring and the tensile force at the other end of the ring, and thus can lightly rotate without being damaged; and no core is arranged in a channel hole, so that wind resistance cannot be generated during ventilation, the central ring can be connected with an air pipe or an air opening structure in a sleeved manner, and the air pipe or the air opening structure can freely rotate integrally.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, and in particular relates to a double-pedestal gear type ventilation turntable structure. Background technique [0002] With the development of our country's national economy and the improvement of people's living standards, China has become a big power consumer. Since the current power production cannot fully meet the needs of the people, there will be power shortages in certain periods and areas. Among the many reasons for the power shortage, the large increase in electricity consumption of household electrical appliances, especially air conditioners, cannot be ignored. [0003] At present, the power consumption of refrigerators and air conditioners accounts for 85% of household electricity consumption. The annual power consumption of household air conditioners alone is more than 40 billion kWh, which is equivalent to 50% of the maximum power generation of the Three Gorges Hydropower Sta...
