Problems solved by technology

However, the gearboxes used in the existing power rakes mostly use cylindrical spur gears for transmission, which has large vibration and noise. When the speed ratio is large, the overall size of the gearbox is large. The gears and shafts are connected by flat keys, which is inconvenient to install and poor in alignment. , when the axial shear force is too large, it is easy to damage the key and shaft

Abstract

The invention discloses a power-driven rake gearbox, which comprises a housing, and the inside of the housing is equipped with input shafts and transmission shafts arranged in parallel and horizontally, and the left ends of the input shafts and transmission shafts are respectively connected with active driving shafts engaged with each other. Gear and driven gear, the right end of the input shaft is connected with a driving bevel gear, the top of the housing is installed with a vertical bevel gear shaft, and the bevel gear at the bottom end of the bevel gear shaft is engaged with the driving bevel gear , the right end of the transmission shaft is connected with a driven bevel gear, and an output shaft arranged horizontally and perpendicular to the input shaft is installed in the side wall of the housing, and one end of the output shaft inside the housing is connected with an arc gear, and the arc gear is engaged with the driven bevel gear on the transmission shaft. The invention has stable and reliable transmission, low vibration and noise, compact internal structure, small overall size, spline connection, prolongs the service life of the equipment, and reduces maintenance costs.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a power-driven rake gearbox. Background technique [0002] A power harrow refers to a machine tool that uses the power output shaft of the tractor to drive the working parts through the universal joint transmission shaft and the transmission system to perform soil breaking and land preparation in dry fields. land preparation machinery. However, the gearboxes used in the existing power rakes mostly use cylindrical spur gears for transmission, which has large vibration and noise. When the speed ratio is large, the overall size of the gearbox is large. The gears and shafts are connected by flat keys, which is inconvenient to install and poor in alignment. , when the axial shear force is too large, it is easy to damage the key and shaft. For this reason, we have designed a power drive rake gearbox to solve the above problems. Contents of the invention [0003] The purpose of t...
