Description

Technical Field

[0001] This utility model belongs to the field of air compressor technology, and specifically relates to a new type of wear-resistant air compressor. Background Technology

[0002] An air compressor is a device that converts mechanical energy into gas pressure energy. Its core function is to generate high-pressure gas by compressing air, providing a power source for industrial production, construction, energy development, and other fields. Its working principle is similar to that of an air pump, but it boasts higher efficiency and pressure output capability.

[0003] During the operation of an air compressor, the crankshaft and connecting rod, as core transmission components, bear enormous gas pressure and inertial forces. Due to long-term high-speed operation and periodically changing loads, wear easily occurs between the crankshaft and connecting rod. This not only affects the performance of the air compressor but may also shorten its service life and increase maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel air compressor that reduces wear between the crankshaft and connecting rod.

[0005] The objective of this utility model can be achieved through the following technical solution: A novel wear-resistant air compressor, comprising a crankcase and a double-headed cylinder, wherein the double-headed cylinder is fixedly installed on both sides of the top of the crankcase and is interconnected with the interior of the crankcase, characterized in that the double-headed cylinder is provided with a piston chamber for the piston to reciprocate, and a double-headed connecting rod is provided within the double-headed cylinder, the double-headed connecting rod being a split cross structure, with one end of the double-headed connecting rod installed in the piston chamber, and a through hole provided at the confluence of the other ends of the double-headed connecting rod. The crankcase contains a crankshaft rod, which is inserted into the through hole of the double-ended connecting rod and extends to the outside of the crankcase. A crankshaft plate is mounted on the crankshaft rod and installed on both sides of the double-ended connecting rod. A groove is formed on the inner wall of the crankshaft plate, and a ball bearing is disposed within the groove. A fixing element is located within the groove to prevent the ball bearing from shifting. An opening groove corresponding to the groove is provided on the outer wall of the double-ended connecting rod, and a mounting hole is provided in the opening groove, with an elastic component disposed within the mounting hole.

[0006] In the aforementioned novel wear-resistant air compressor, the elastic component is provided with a fixing pad corresponding to the ball bearing, and the fixing pad is arc-shaped. An elastic bracket is provided at the bottom of the fixing pad, and a reset spring with a reset function is provided inside the elastic bracket.

[0007] In the aforementioned novel wear-resistant air compressor, the crankcase is equipped with an intake pipe for air intake, and the double-headed cylinder is equipped with an exhaust pipe.

[0008] In the aforementioned novel wear-resistant air compressor, a gear for providing power is provided on the end of the crankshaft located outside the crankcase.

[0009] Compared with existing technologies, this new wear-resistant air compressor effectively reduces wear between the crankshaft and connecting rod by adopting designs such as ball bearings and elastic components, thereby improving the service life of the air compressor; the use of rolling friction reduces frictional resistance and improves the transmission efficiency of the air compressor.

Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figures 1 to 4As shown, this novel wear-resistant air compressor includes a crankcase 1 and a double-headed cylinder 2. The double-headed cylinder 2 is fixedly installed on both sides of the top of the crankcase 1 and is interconnected with the interior of the crankcase 1. The double-headed cylinder 2 has a piston chamber 3 for reciprocating piston motion. A double-headed connecting rod 4 is installed inside the double-headed cylinder 2. The double-headed connecting rod 4 has a split, cross-shaped structure, with one end installed in the piston chamber 3 and a through hole 5 at the intersection of the other ends. A crankshaft rod 6 is installed inside the crankcase 1. The crankshaft rod 6 is inserted into the through hole 5 of the double-headed connecting rod 4 and extends outside the crankcase 1. The crankshaft rod 6... A crankshaft plate 7 is provided, which is installed on both sides of the double-ended connecting rod 4. A groove 8 is provided on the inner wall of the crankshaft plate 7, and a ball bearing 9 is provided in the groove 8. The ball bearing 9 is installed in the groove 8 and contacts the outer wall of the double-ended connecting rod 4. A fixing member 10 is provided in the groove 8 to prevent the ball bearing 9 from shifting or falling off during the movement, so as to ensure that the ball bearing 9 can roll stably in the groove 8. An opening groove 11 corresponding to the groove 8 is provided on the outer wall of the double-ended connecting rod 4. An installation hole 12 is provided on the opening groove 11, and an elastic component 13 is provided in the installation hole 12.

[0017] When the air compressor is working, the piston reciprocates within the double-ended cylinder 2, transmitting power to the crankshaft rod 6 via the double-ended connecting rod 4. The crankshaft rod 6 rotates within the crankcase 1, driving the crankshaft discs 7 to move together. Because ball bearings 9 are installed on the inner wall of the crankshaft discs 7, these ball bearings 9 create rolling friction with the outer wall of the double-ended connecting rod 4, reducing frictional resistance and wear. Simultaneously, the elastic component 13 provides cushioning and shock absorption between the double-ended connecting rod 4 and the crankshaft discs 7, further protecting the components from damage caused by impacts and vibrations.

[0018] To elaborate further, the elastic component 13 is provided with a fixing pad 14 corresponding to the ball 9, and the fixing pad 14 is arc-shaped. The fixing pad 14 is arc-shaped and installed on the elastic component 13, corresponding to the ball 9. An elastic bracket 15 is provided at the bottom of the fixing pad 14, and a return spring 16 with a reset function is provided inside the elastic bracket 15. The return spring 16 is installed inside the elastic bracket 15 and has a reset function. When relative movement occurs between the double-ended connecting rod 4 and the crankshaft plate 7, the return spring 16 can absorb part of the impact energy and quickly restore the elastic component 13 to its original position after the movement ends.

[0019] To elaborate further, the crankcase 1 is equipped with an intake pipe 17 for air intake, and the dual-head cylinder 2 is equipped with an exhaust pipe 18.

[0020] To elaborate further, a gear 19 for providing power is provided on one end of the crankshaft rod 6 located outside the crankcase 1.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document frequently uses terms such as crankcase 1, double-ended cylinder 2, piston chamber 3, double-ended connecting rod 4, through hole 5, crankshaft rod 6, crankshaft plate 7, groove 8, ball bearing 9, fastener 10, opening slot 11, mounting hole 12, elastic component 13, fixing pad 14, elastic bracket 15, return spring 16, intake pipe 17, exhaust pipe 18, gear 19, etc., the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
