Drive shaft capable of preventing overload fracture

Abstract

The invention discloses a drive shaft capable of preventing overload fracture, which comprises a half-coupling 1, a half-coupling 2, a connector 1, a connector 2, a sleeve and a safety pin, wherein the left end of the half-coupling 1 is connected with a gearbox input shaft through a key; the right end of the half-coupling 2 is connected with a main motor output shaft through a key; the right side of the half-coupling 1 is fixed and connected with the connector 2 through a bolt; the left end of the connector 1 is welded with a shaft head; the shaft head can be inserted to an internal cavity on the right end of the connector 2 to be fixed axially and rotate radially; and the right end of the connector 1 is fixedly connected with the half-coupling 2 through a bolt. The drive shaft capable of preventing overload fracture can provide a substitute for a high-torque drive shaft used by flour mill equipment or other heavy equipment; and thus, the drive shaft capable of preventing overload fracture enhances the safety and reliability of the equipment, can better protect related equipment and personnel from damage, can greatly lower the maintenance cost and shorten the maintenance time, effectively enhances the production efficiency, and brings in considerable economic benefit.

Description

technical field [0001] The invention relates to a transmission shaft preventing overload fracture. Background technique [0002] At present, the output torque of the main drive shaft of the grinding equipment used in China is large, the force is complex, and the working conditions are harsh. Once the shaft breaks due to overload or fatigue failure, the broken two-section shaft will fall downward due to gravity, and the resulting impact is easy. It will lead to damage to the main equipment, and there may be casualties, which will bring serious losses to users; and replacing the new shaft will cause a large waste of materials, and the workload of replacement is also very large, which is time-consuming, laborious and expensive, and delays production time. It takes a long time. [0003] Therefore invent a kind of transmission shaft that can prevent overload fracture and become the technical problem demanding prompt solution. Contents of the invention [0004] In response to ...
