Abstract
An axially fixing device for a colter shaft includes a colter shaft and a colter shaft support arm. The colter shaft is connected with the colter shaft support arm by the bearing whose internal ring is fixed on the colter shaft; the external ring of the bearing is tightly assembled with the installation hole of the colter shaft support arm; an oil seal is arranged between the colter shaft and the colter shaft support arm; an axial push-stop part is arranged on the internal wall of the installation hole on the colter arm or bearing; the axial push-stop part is an axial push-stop ring which is an elastic clip spring; the internal wall of the installation hole of the colter shaft support arm is provided with a ring trough where the elastic clip spring is blocked; a bearing cover is arranged on the installation hole of the colter shaft support arm and is provided with a screw for filling with lubrication; the screw is assembled with the plug screw. As the colter shaft is axially fixed, the utility model effectively prevents the axial displacement of colter shaft, prolongs the service life of the oil seal and the bearing and is suitable for the installation of the colter shaft of the rotary tiller and the rotary tillage sowing adjusting machine with different types.
Description
Technical field:
The utility model relates to the rotovator that uses with walking tractor matching and rotary tillage and transfers and broadcast the coulter shaft axial restraint device that the machine of broadcasting is transferred in machine, particularly rotovator and rotary tillage.
Background technology:
Existing rotovator and rotary tillage transfer the structure of the coulter shaft fixture of the machine of broadcasting to be: contain coulter shaft, coulter shaft support arm, coulter shaft is connected by bearing with the coulter shaft support arm, the inner ring of bearing is fixed on the coulter shaft, installing hole close-fitting on the outer ring of bearing and the coulter shaft support arm has also been installed oil sealing between coulter shaft and the coulter shaft support arm.Owing to have only radially fixing between coulter shaft and the coulter shaft support arm, there is not axial restraint, when carrying out the rotary tillage operation, the rotation of coulter shaft is subjected to the influence of weeds resistance, easily make and produce axial force on the coulter shaft, cause between coulter shaft and the coulter shaft support arm and produce displacement to axial, perhaps because the influence of colter unbalance stress, also can make and produce axial force on the coulter shaft, cause equally between coulter shaft and the coulter shaft support arm and produce displacement to axial, and, working time is long more, and the axial force that produces on the coulter shaft is just big more, causes the displacement to axial that produces between coulter shaft and the coulter shaft support arm also big more, weeds also just are easy to enter owing in the formed space of displacement to axial between coulter shaft and the coulter shaft support arm, finally cause the damage of oil sealing and bearing.
The utility model content:
The purpose of this utility model be to overcome prior art for foot, a kind of coulter shaft axial restraint device is provided.
Solution of the present utility model is: contain coulter shaft, coulter shaft support arm, coulter shaft is connected by bearing with the coulter shaft support arm, the inner ring of bearing is fixed on the coulter shaft, installing hole close-fitting on the outer ring of bearing and the coulter shaft support arm, between coulter shaft and the coulter shaft support arm oil sealing has been installed also, on the installing hole inwall on the coulter shaft support arm or on the bearing axial thrust spare has been installed.
Axial thrust spare is axial thrust ring, axial thrust nail or axial thrust piece.
The axial thrust ring is an elastic circlip, on the installing hole inwall on the coulter shaft support arm annular groove is arranged, and elastic circlip is stuck in the annular groove.
Bearing is rolling bearing or radial thrust bearing.
Flexible jump ring on the outer ring of rolling bearing, the end of the installing hole on the coulter shaft support arm is fluted, and the elastic circlip on the housing washer is stuck in the groove.
On the installing hole on the coulter shaft support arm bearing cap has been installed, the screw that adds lubricating oil is arranged on the bearing cap, screw and plug screw match.
The utility model so prevented the axial displacement of coulter shaft effectively, has prolonged the service life of oil sealing and bearing because coulter shaft has been carried out axial restraint, is applicable to the rotovator of various models and the installation that coulter shaft on the machine broadcast in the rotary tillage accent.
Description of drawings:
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure: 1---bearing cap; 2---paper washer; 3---elastic circlip; 4---rolling bearing; 5---oil sealing; 6---oil sealing; 7---colter; 8---the colter holder; 9---axle sleeve; 10---connecting axle; 11---the shoulder lattice; 12---cover for seat; 13---elastic circlip; 14---the coulter shaft support arm; 15---plug screw; 16---screw.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Contain coulter shaft, coulter shaft support arm 14, coulter shaft is welded by connecting axle 10 and axle sleeve 9, colter holder 8 has been installed on the axle sleeve 9, colter 7 is installed on the colter holder 8, connecting axle 10 is connected by rolling bearing 4 with coulter shaft support arm 14, the inner ring of rolling bearing 4 is fixed on the connecting axle 10, one end of the inner ring of rolling bearing 4 is by elastic circlip 3 axial restraints, the other end of the inner ring of rolling bearing 4 is by an end axial restraint of cover for seat 12, the other end of cover for seat 12 is against on the shoulder lattice 11 of connecting axle 10, installing hole close-fitting on the outer ring of rolling bearing 4 and the coulter shaft support arm 14, between the installing hole on cover for seat 12 and the coulter shaft support arm 14 oil sealing 5 has been installed also, 6, bearing cap 1 has been installed on the coulter shaft support arm 14, between bearing cap 1 and the coulter shaft support arm 14 paper washer 2 is arranged, the screw 16 that adds lubricating oil is arranged on the bearing cap 1, screw 16 matches with plug screw 15, by screw 16 regularly or aperiodically is that rolling bearing 4 adds lubricating oil, prolongs the service life of rolling bearing 4.Control connection axle 10 is made axially movable version following several scheme: scheme one: process annular groove on the installing hole inwall on the coulter shaft support arm 14, elastic circlip 13 is stuck in the annular groove, and elastic circlip 13 is between the outer ring and oil sealing 5 of rolling bearing 4.Scheme two: adopting model is the 6207N rolling bearing, flexible jump ring on the outer ring of this model rolling bearing, and the end of the installing hole on the coulter shaft support arm 14 processes groove, and the elastic circlip on the housing washer is stuck in the groove.Also can change rolling bearing 4 into radial thrust bearing, the direction of the axial force that the radial thrust bearing when making work produces is opposite with the direction of connecting axle 10 stressed generation displacements, to reduce the axial displacement of connecting axle 10.
