[0002] At present, the connection between the engine and the gearbox of the tiller generally adopts a flywheel installed on the power output shaft of the engine, and is connected to the flywheel of the clutch assembly with a belt or a chain to realize the power input. The transmission mechanism of this input mode Set outside the engine and gearbox, the design of this transmission mechanism not only increases the volume of the tiller head, but also reduces the utilization rate of the engine output power due to the friction loss generated during the power transmission process. Increased material cost, and there are disadvantages such as high transmission noise

The invention discloses a direct-connected gearbox of a mini-tiller. The direct-connected gearbox of the mini-tiller comprises a spline housing, a clutch assembly and an input shaft. The direct-connected gearbox is characterized in that the spline housing is arranged at the power input end of the clutch assembly, the other end of the spline housing is directly connected to a power output shaft of an engine, the power output end of the clutch assembly is connected with an input shaft, a transmission gear is arranged on the input shaft, the transmission gear is meshed with a change gear set, the change gear set is meshed with output bevel teeth, and the output bevel teeth are meshed with bevel teeth on the output shaft. The direct-connected gearbox of the mini-tiller has the advantages that the design is reasonable, the structure is simple, direct connection is achieved, the whole machine head is designed to be simpler and smoother, loss of power in a transmission process is reduced to the minimum, and transmission noise is lowered. The direct-connected gearbox can be applied to universal mini-tillers using diesel engines with different powers or gasoline engines with different powers.
Description
technical field [0001] The invention relates to a gearbox for agricultural machinery, in particular to a direct-connected gearbox for a tiller with simple structure and convenient operation. Background technique [0002] At present, the connection between the engine and the gearbox of the tiller generally adopts a flywheel installed on the power output shaft of the engine, and is connected to the flywheel of the clutch assembly with a belt or a chain to realize the power input. The transmission mechanism of this input mode Set outside the engine and gearbox, the design of this transmission mechanism not only increases the volume of the tiller head, but also reduces the utilization rate of the engine output power due to the friction loss generated during the power transmission process. The material cost is increased, and there are disadvantages such as relatively high transmission noise. Contents of the invention [0003] The purpose of the present invention is to provide ...
