Problems solved by technology

[0002] Most of the current piston compressors are crankshaft-connecting-rod piston transmission, and the stroke of the piston is limited by the distance from the crank arm to the center of rotation. However, increasing the cross-sectional area of ​​the cylinder and the piston or increasing the speed of the motor means that the power of the motor needs to be increased. The increase in the power of the motor will lead to an increase in the movement frequency of the piston and a decrease in the life of the piston. Moreover, the increase in the power of the motor will lead to an increase in noise

Embodiment Construction

[0020] like Figure 1-4 As shown, a gear-driven piston compressor includes a cylinder block 1, and both ends of the cylinder block 1 are provided with pistons 2 that cooperate with the inner wall of the cylinder block 1, that is, the diameter of the piston 2 is the same as the inner diameter of the cylinder block 1, and it is easy to It is understood that both ends of the cylinder block 1 are provided with an intake valve 13 and an exhaust valve 14 .

[0021] A bottom plate 3 is connected between the two pistons 2, and a thrust plate 4 is placed on the top of the bottom plate 3, that is, the thrust plate 4 can move freely on the bottom plate 3. There is a rack 501, the two racks 501 can be integrally formed, and then welded with the thrust plate 4 or fixed by screws, so that the thrust plate 4 and the gear block 5 can move synchronously. The meshing gear 6, the gear 6 is connected with the driving mechanism 7 that drives it to rotate, the elastic pieces 10 are provided on bot...

Abstract

The invention relates to the technical field of piston compressors, and provides a gear transmission piston type compressor which comprises a cylinder body, pistons matched with the inner wall of the cylinder body are arranged at the two ends of the cylinder body, a bottom plate is connected between the two pistons, a thrust plate is placed at the top of the bottom plate, a tooth block is arranged on the thrust plate, and racks are arranged on the two sides of the tooth block. A gear capable of being meshed with the rack is arranged above the thrust plate, the gear is connected with a driving mechanism driving the gear to rotate, elastic pieces are arranged on the two sides of the end of the thrust plate, one end of each elastic piece is fixedly connected with the bottom plate, and the other end of each elastic piece is fixedly connected with the thrust plate. The stroke of the piston can be increased only by increasing the length of the rack on the premise of keeping the power of the motor unchanged, so that the air suction and exhaust amount is increased, noise increase can be avoided by keeping the power of the motor unchanged, the stroke of the piston is increased, the reciprocating motion frequency of the piston can be reduced, and the service life of the piston is prolonged.

Description

technical field [0001] The present invention relates to the technical field of piston compressors, in particular to a gear-driven piston compressor. Background technique [0002] Most of the current piston compressors are crankshaft connecting rod type piston transmission, which is limited by the distance between the crank arm and the rotation center, so that the stroke of the piston is limited. However, increasing the cross-sectional area of ​​the cylinder and the piston or increasing the speed of the motor means that the power of the motor needs to be increased. The increase in the power of the motor will lead to an increase in the frequency of the piston movement and a decrease in the life of the piston. And the increased power of the motor will lead to increased noise. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a gear-driven piston compressor to solve the above-mentioned technical problems. [0004] Embodiments of the present...
