Disc harrow axle base

Abstract

The invention relates to a disc harrow axle base. The disc harrow axle base comprises an ear part arranged outside a shell and connected with a harrow body; the disc harrow axle base is characterized in that: a left-handed thread and a right-handed thread are arranged at two ends of the inner side of the shell, a core shaft is arranged inside the shell, a convex edge is arranged at the middle part of the core shaft, tapered-roller bearings are respectively arranged at two sides of the convex edge, and the tapered-roller bearings with tapers are assembled oppositely; double oil seals are arranged at the inner sides of a left-handed pressure cover and a right-handed pressure cover, sealing rings are arranged at outer sides of the left-handed pressure cover and a right-handed pressure cover, then the left-handed pressure cover and the right-handed pressure cover are sheathed on the core shaft and are respectively connected with the tapered-roller bearings; the left-handed pressure cover and the right-handed pressure cover are screwed on the left-handed thread and the right-handed thread of the shell, semi-intercalated pipes are arranged on the left-handed pressure cover and the right-handed pressure cover respectively, the semi-intercalated pipes are clamped at two ends of the core shaft and are connected with the left-handed pressure cover and the right-handed pressure cover in a clearance fitting manner. The disc harrow axle base has a simple structure and good practicability, the repairing and maintaining operations during production are reduced and the producing efficiency is improved.

Description

technical field [0001] The invention relates to a disc harrow shaft seat, which belongs to the technical field of agricultural machinery. Background technique [0002] In the known technology, the axle seat for raking generally selects the nylon tile axle seat for use. Although it has good water and soil resistance, its durability is not high, and it cannot bear the axial and radial forces. Although the outer spherical self-aligning bearing and the ordinary radial ball bearing are equipped with an oil seal protection device, the waterproof and mud-proof effects are not very satisfactory. Because the rake machine is working, the axial force and radial force are large, so it is durable The degree also does not meet the requirements. Contents of the invention [0003] The problem solved by the invention is to overcome the shortcomings of the prior art and provide a disc harrow shaft seat. [0004] The technical solution of the present invention is: the shaft seat of the dis...

Problems solved by technology

[0002] According to the known technology, the axle seat for raking is generally made of nylon tile axle seat. Although it has good water and soil resistance, its durability is not high, and it cannot withstand axial and radial forces.

Although the outer spherical self-aligning bearing and the ordinary radial ball bearing are equipped with an oil seal protection device, the waterproof and mud-proof effects are not very satisfactory. Because the rake machine is working, the axial force and radial force are large, so it is durable degree also does not meet the requirements
