Abstract

The invention belongs to the technical field of rotary tractor parts, particularly relates to a driving shaft, and solves the technical problems that the prior art is not reasonable enough and the like. The driving shaft comprises a shaft body, and is characterized in that a gear mounting part connected with a driving gear is arranged at one end of the shaft body and a hub mounting part connectedwith a hub is arranged at the other end thereof, wherein the hub mounting part is columnar; six contact surfaces of the hub mounting part are equal in size; a chamfered surface is arranged between anytwo adjacent surfaces of the six contact surfaces. Compared with the prior art, the driving shaft provided by the has the advantages of reasonable design, a simple structure, high structural strength, stable working, stable and firm assembling, a long service life and unlikeliness in damage.

Description

technical field [0001] The invention belongs to the technical field of rotary tillage tractor components, in particular to a drive shaft. Background technique [0002] A rotary tillage tractor is a combination of a rotary tiller and a tractor. The tractor is composed of systems or devices such as engine, transmission, walking, steering, hydraulic suspension, power output, electrical instruments, driving control and traction. The power of the engine is transmitted to the driving wheels through the transmission system to make the tractor run. Agricultural, industrial and special-purpose tractors are classified according to function and purpose; wheeled, crawler-type, boat-shaped tractors and self-propelled chassis are classified according to structure type. [0003] For example, the Chinese patent document discloses a multifunctional walking tractor [application number: 95225151.5], which moves the engine of the walking tractor to the back of the gearbox. Machines, winches,...
