A transmission device for drive shaft of cutter head of farmland ditching machine

Abstract

The invention discloses a transmission for a driving shaft of a cutting wheel of a farmland ditching machine. The transmission comprises a driving shaft assembly, a speed reducer and a bearing block assembly. The driving shaft assembly is used for providing power, the speed reducer is used for adjusting and outputting the power, the bearing block assembly is used for mounting the driving shaft assembly on a speed reducer shell, one end of a bearing supporting sleeve is connected with a bevel gear with curved teeth, the bevel gear with the curved teeth is arranged in the speed reducer, a fastening nut for adjusting pre-tightness of tapered roller bearings is arranged at the other end of the bearing supporting sleeve, an output end of the driving shaft of the driving shaft assembly penetrates the certain end of the bearing supporting sleeve and is connected with the bevel gear with the curved teeth, the fastening nut is arranged at the certain end of the bearing supporting sleeve, and the bevel gear with the curved teeth is fixed to the other end of the bearing supporting sleeve. The transmission has the advantages that the bevel gear with the curved teeth is indirectly connected with the driving shaft of the cutting wheel by the bearing supporting sleeve, so that the problem of difficulty in connecting an existing bevel gear with curved teeth with an existing driving shaft can be appropriately solved, all torque can be assuredly transmitted by the driving shaft of the cutting wheel, and meshing clearance and meshing marks of a bevel gear pair can be conveniently adjusted when necessary.

Description

technical field [0001] The invention relates to a transmission device, in particular to a transmission device used for the driving shaft of the cutter head of a farmland ditching machine. Background technique [0002] The general design is to directly install the drive shaft of the cutter head on the reducer housing through a pair of tapered bearings. Although the structure is simple, various adjustments are not easy to carry out, and it is inconvenient to use. As for the drive shaft of the cutter head equipped with a spiral bevel gear with a large driving power, in order to ensure the correct meshing clearance and meshing marks, it is necessary to design and install a reasonable and scientific adjustment mechanism. Easy and reliable adjustment during maintenance. In the design and application, the connection between the spiral bevel gear and the drive shaft of the cutter head is indirectly connected through the bearing support sleeve, which properly solves the connection p...
