MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202537114190 A) filed by Nanchang Highly Electrical Appliances; and Shanghai Highly Electrical Appliances on November 20, 2025, for Crankshaft, Compressor And Refrigeration Apparatus.
Inventors include Chen, Jingyu; Luo, Jiejun; and Ling, Bingjian.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: A crankshaft, a compressor and a refrigeration apparatus. The crankshaft (10) comprises a long shaft portion (11), an eccentric portion (12) and a short shaft portion (13), which are sequentially arranged in an axial direction. The shaft diameter of the long shaft portion (11) is r1, and the shaft diameter of the short shaft portion (13) is r2, satisfying: 18 mm=r1=20 mm, and 16 mm=r2=18 mm. The structure reduces the shaft diameters of the long and short shafts of the crankshaft, and further reduces contact areas between the crankshaft and upper and lower bearings, and reduces the contact friction between the crankshaft and the upper and lower bearings, thereby reducing the mechanical loss of the compressor, and improving the operating efficiency and performance of the compressor.
