Embodiment 1

[0028] Such as figure 1 As shown, a crankshaft installation structure of an oil-free air compressor, the oil-free air compressor includes a motor 1 and a crankshaft 2, the end of the motor 1 is fixedly connected to a crankcase 4, and the outer wall of the crankcase 4 is fixedly connected to a cylinder body 5. There is a piston 51 inside the cylinder body 5. The rotating shaft 11 is the motor shaft of the motor 1. The rotating shaft 11 extends into the crankcase 4. The crankshaft 2 is located in the crankcase 4 and connected to the end of the rotating shaft 11. The piston 51 passes through the connecting shaft. The rod assembly 52 is connected to the crankshaft 2 .

[0029] Specifically, combine figure 2 As shown, the end of the crankshaft 2 has a disk-shaped counterweight 21, and the end surface of the counterweight 21 is provided with a mounting hole 22, the mounting hole 22 is arranged along the axial direction of the crankshaft 2, and the outer peripheral surface of the c...

Embodiment 2

[0031] The crankshaft installation structure of the oil-free air compressor is basically the same as that of Embodiment 1, the difference is that Figure 6 As shown, there are several positioning protrusions 34 on the end face of the positioning section 32, and the positioning protrusions 34 are arranged along the circumferential direction, and the positioning protrusions 34 are in the shape of tops. the underside.

Abstract

The invention provides a crankshaft installing structure of an oilless air compressor, and belongs to the technical field of air compressors. The problem that a crankshaft of an existing oilless air compressor is prone to loosening is solved. According to the crankshaft installing structure of the oilless air compressor, the oilless air compressor comprises a rotation shaft, the crankshaft installing structure comprises a positioning bolt, a positioning groove is formed in the outer wall of the rotation shaft, and an installing hole is formed in the end face of the crankshaft. The rotation shaft is inserted and connected in the installing hole of the crankshaft. The crankshaft is further provided with a positioning screw hole. The positioning bolt comprises a thread section and a positioning section with the outer circumference face being a straight barrel face. The thread section of the positioning bolt is in screw joint in the positioning screw hole, the positioning section of the positioning bolt is inserted in the positioning groove of the rotation shaft, the end face of the positioning section is tightly pressed on the bottom face of the positioning groove, and the outer diameter of the positioning section is matched with the width of the positioning groove. By means of the crankshaft installing structure of the oilless air compressor, crankshaft installation is more stable.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and relates to a crankshaft installation structure of an oil-free air compressor. Background technique [0002] The oil-free air compressor is a miniature reciprocating piston compressor. When the motor drives the compressor crankshaft to rotate, through the transmission of the connecting rod, the piston with self-lubrication without adding any lubricant will reciprocate. The working volume formed by the top surface of the piston and the top surface of the piston will change periodically. Depending on the number of cylinders of the oil-free air compressor, the connection method between the connecting rod and the motor is also different. When the number of cylinders of the air compressor is small and the displacement is high, it is necessary to connect the crankshaft to the motor shaft. The connecting rod of the piston is directly sleeved on the crankshaft. [0003] For example, the Chin...
