Abstract
The invention discloses an overload protection device on a tailing auger shaft. The purpose of the invention is to provide an overload protection device on a tailing auger shaft, which can effectively protect the tailing auger shaft. The technical scheme is that the overload protection device on the tailing auger shaft comprises a tailing auger shaft and a belt pulley, wherein the belt pulley and the tailing auger shaft are rotatably connected together via ball bearings on two bearings. A spring between the belt pulley and a check ring is a conical spring. The technical effect of the invention is that the coefficient of friction is greatly decreased because the frictions between the tailing auger shaft and the bearings are rolling frictions; the impact to the tailing auger shaft is greatly reduced when the tailing auger shaft cannot rotate by obstruction, thereby the service life of the tailing auger shaft is prolonged.
Description
Technical field
The present invention relates to grain header, particularly the overload protection arrangement on the tailing auger shaft.
Background technology
Overload protection arrangement on the tailing auger shaft on the existing grain header; tooth shell type overload protection arrangement has been installed on belt pulley; when tailing auger shaft is subjected to resistance and can not rotates; the tooth cover skids; powder alloy in the belt wheel overlaps and the tailing auger between centers is a sliding friction, causes the gap between powder alloy cover and the tailing auger shaft to increase easily, in rotation process tailing auger shaft is produced impact; cause tailing auger shaft in impulsion, to sustain damage, shorten its service life.
Summary of the invention
The purpose of this invention is to provide the overload protection arrangement on a kind of tailing auger shaft that can effectively protect tailing auger shaft.Technical solution of the present invention is done in such a way that the overload protection arrangement on the tailing auger shaft, comprises tailing auger shaft, belt pulley, it is characterized in that: be rotatably connected by the ball on the bearing between belt pulley and the assorted surplus axle.Bearing has two.Spring between belt pulley and the back-up ring is a volute spring.Technique effect of the present invention is: because of being rolling friction between tailing auger shaft and the bearing, greatly reduce coefficient of friction, when tailing auger shaft is obstructed can not rotate the time, effectively reduce impulsive force, thereby prolonged the service life of tailing auger shaft tailing auger shaft.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Drawing explanation: 1, belt pulley; 2, bearing; 3, oil sealing; 4, volute spring; 5, back-up ring; 6, tailing auger shaft.
Embodiment
In conjunction with the accompanying drawings the present invention is described in further detail, further improve on the original base of the present invention, change the powder alloy cover in the belt pulley 1 into bearing 2, the right side of bearing is provided with oil sealing 3, be provided with volute spring 4 between belt pulley 1 and the back-up ring 5, change the rolling friction of bearing and tailing auger between centers into by the sliding friction of 6 of powder alloy cover and tailing auger shafts, effectively reduce coefficient of friction.
