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
The present invention relates to a kind of disc harrow axle bed, belong to the technical field of farm machinery aspect.
Background technique
Known technology, rake is generally selected nylon watt axle bed with axle bed, although its water-fast resistance to soil nature can be good, durability is not high, can not bear strength axially and radially.Although outer spherical surface self-aligning bearing and common centripetal ball bearing have installed oil sealing protective gear additional, waterproof, anti-earth effect is not very desirable, due to rake machine at work, axial force, radial force are all very large, therefore, durability can not meet the demands equally.
Summary of the invention
The problem that the present invention solves is to overcome the deficiency that original technology exists, and a kind of disc harrow axle bed is provided.
Technological scheme of the present invention is: disc harrow axle bed, comprise, in housing (1) outside, be provided with and the ear of harrowing body and being connected, it is characterized in that: at two ends, housing (1) inner side, be provided with positive left-hand thread screw thread, in housing (1) inside, be provided with mandrel (2), at mandrel (2) middle part, be provided with both sides, ， convex edge, convex edge and be separately installed with cone roller bearing and hold (3), have the cone roller bearing of tapering to hold (3) and assemble in opposite directions; Dual-oil seal (5) is installed in inner side at left-handed gland (6) and dextrorotation gland (7), and seal ring (4) is installed in outside, is then sleeved on mandrel (2) upper, holds (3) be respectively connected with cone roller bearing; And with left-handed gland (6) and dextrorotation gland (7), be tightened on the positive left-hand thread screw thread of housing (1); On left-handed gland (6) and dextrorotation gland (7), be separately installed with half pipe (8), half pipe (8) is clamped together with the two ends of mandrel (2).
Half pipe (8) and left-handed gland (6), dextrorotation gland (7) are connected for Spielpassung.
By half pipe (8), left-handed gland (6), dextrorotation gland (7) and dual-oil seal (5), formed multiple tracks Back Word type grave mound structure.
In order to have increased waterproof, the ability of anti-earth and life-span and axial force and the radial force of raising bearing, on left-handed gland (6), dextrorotation gland (7), be provided with the device of O RunddichtringO (4) and dual-oil seal (5).
The present invention is simple in structure, has good practicability, has reduced the maintenance in production work, maintenance, thereby has improved manufacturing efficiency.
Accompanying drawing explanation
Fig. 1 is blast structural representation of the present invention;
Fig. 2 is sectional structure schematic diagram of the present invention.
In figure: 1 housing, 2 mandrels, 3 cone roller bearings hold, 4 seal rings, 5 dual-oil seals, 6 left-handed glands, 7 dextrorotation glands, 8 half pipes.
Embodiment
As shown in Figure 1 and Figure 2, in housing 1 outside, be provided with and the ear of harrowing body and being connected, at housing 1 two ends, inner side, be provided with positive left-hand thread screw thread, in housing 1 inside, be provided with mandrel 2, at mandrel 2 middle parts, be provided with both sides, ， convex edge, convex edge and be separately installed with cone roller bearing and hold 3, have the cone roller bearing of tapering to hold 3 assemblings in opposite directions.Dual-oil seal 5 is installed in inner side at left-handed gland 6 and dextrorotation gland 7, and seal ring 4 is installed in outside, is then sleeved on mandrel 2, holds 3 be respectively connected with cone roller bearing; And with left-handed gland 6 and dextrorotation gland 7, be tightened on the positive left-hand thread screw thread of housing 1.On left-handed gland 6 and dextrorotation gland 7, be separately installed with 8, half pipes 8 of half pipe is pressed together the present invention by harrowing the clamping force of the tightening nut of axle square steel with the two ends of mandrel 2 when assembling complete machine.Half pipe 8 and left-handed gland 6, dextrorotation gland 7 are connected for Spielpassung.
The present invention has formed multiple tracks Back Word type grave mound structure by half pipe 8, left-handed gland 6, dextrorotation gland 7 and dual-oil seal 5, on left-handed gland 6, dextrorotation gland 7, be provided with the device of O RunddichtringO 4 and dual-oil seal 5 simultaneously, so not only greatly increase the ability of waterproof of the present invention, anti-earth, also improved life-span and the axial force radial force of bearing simultaneously.Guarantee the stable permanent operation of the machine of harrowing.
