Description

Technical Field

[0001] The utility model relates to the technical field of vortex air compressors, and more specifically to a main shaft mechanism of a vortex air compressor. Background Art

[0002] The main shaft of the scroll air compressor is one of the most important parts of the air compressor. Figure 1 As shown, the main shaft 1 of the air compressor is installed in the bracket body 2, one end of which is keyed to the pulley 3, which is connected to the motor through a belt, and the motor transmits power; the other end (the eccentric shaft end of the air compressor main shaft) is matched with the hole in the core of the moving plate assembly 4 through a cylindrical roller bearing 5. The eccentric wheel of the main shaft 1 of the air compressor is provided with an oil passage hole, that is, a horizontal hole 6 and a vertical hole 7 that are vertically connected, and the port of the vertical hole 7 is connected to the oil injection gun nozzle 8 (see Figure 2-3 ). If oiling is required, connect the oiling gun nozzle to the oiling nozzle, and inject grease by squeezing the oiling gun. The grease enters from the oiling nozzle, passes through the vertical hole and then the horizontal hole, and finally penetrates into the cylindrical roller bearing in the core hole of the moving plate assembly.

[0003] The setting of this oil passage hole is to effectively replenish the cylindrical roller bearing grease in the core of the moving plate assembly during the use and maintenance of the air compressor.

[0004] However, this oil hole structure has a great disadvantage. Since the main shaft of the air compressor is installed in the cavity of the bracket body, it is usually necessary to fill the cylindrical roller bearing grease at the core of the moving plate assembly before the whole air compressor is assembled. After the whole air compressor is assembled, if grease is added, the oil filling gun nozzle must be inserted into the oil filling hole of the bracket, and then the main shaft of the air compressor is rotated until the oil filling gun nozzle and the oil filling nozzle on the main shaft are connected. The above operation is completed in a closed environment, and the scroll air compressor is usually installed in the box, which makes the operation more difficult, and even the box must be unpacked for oiling, which greatly affects the maintenance of the air compressor head. Utility Model Content

[0005] The utility model aims to provide a main shaft mechanism of a scroll air compressor to solve the technical problems existing in the above-mentioned background technology.

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the sake of illustration and convenience of description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0022] like Figure 4-7 As shown, the technical solution of the utility model provides a main shaft mechanism of a scroll air compressor, including a main shaft body 1, a pulley 2 is arranged at one end of the main shaft body 1, a core long hole 3 is penetrated through the middle of the main shaft body 1, a connecting piece is detachably arranged on the main shaft body 1 and close to one end of the pulley 2, the connecting piece is connected to the core long hole 3, and an oiling nozzle 7 is arranged on the connecting piece.

[0023] The connecting piece realizes the connection between the oiling nozzle 7 and the main shaft body 1. In this solution, the oiling nozzle 7 is set outside the air compressor. When filling oil, the nozzle of the oiling gun is docked on the oiling nozzle 7, and the grease is injected by squeezing the oiling gun. The grease enters from the oiling nozzle 7, passes through the core long hole 3, and finally penetrates into the cylindrical roller bearing in the core hole of the moving plate assembly. Since the oiling nozzle 7 connected to the improved air compressor main shaft mechanism is designed to be outside the air compressor (such as Figure 7 As shown in the figure, the oil filling operation is very convenient, which provides a guarantee for the subsequent maintenance work of the machine head.

[0024] The connecting member is threadedly connected to the spindle shaft body 1. The connecting member includes a hollow bolt 5, an end thread structure 4 is arranged in the spindle shaft body 1, and the hollow bolt 5 is threadedly connected to the spindle shaft body 1. The oil injection nozzle 7 is threadedly connected to the hollow bolt 5. A threaded opening 6 is arranged in the hollow bolt 5, and one end of the oil injection nozzle 7 is screwed into the threaded opening 6.

[0025] The hollow bolt 5 is connected to the end thread structure 4 in the main shaft body 1 to form a passage from the oiling nozzle 7 to the core long hole 3 to ensure that the grease can smoothly pass through the core long hole 3 to reach the cylindrical roller bearing. At the same time, the connector and the oiling nozzle are both detachable, which is convenient for assembly and maintenance.

[0026] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
