Abstract
The invention discloses a taper spline connecting device capable of preventing a cutting disc of a ditcher from loosening. The connecting device comprises a cutting disc shaft bearing seat, nuts, cutting disc spline shafts and wheel vortex spline housings, the cutting disc spline shafts are tightly connected on the cutting disc shaft bearing seat through the corresponding nuts, each wheel vortex spline housing is mounted on the outer periphery of the corresponding cutting disc spline shaft, and spline fit between each cutting disc spline shaft and the corresponding wheel vortex spline housing is taper spline fit. Cutting disc shaft splines and cutting disc wheel vortex spline joints are in taper spline fit, and friction coefficient of fit of the cutting disc spline shafts and wheel vortex splines is increased. When the nuts of the spline shafts are tightened, the cutting disc shaft splines and the cutting disc wheel vortex spline joints are enabled not to loosen, thus the spline portion cannot be impacted and deformed due to loosening, the splines cannot prematurely damage an urban power transmission function, and difficulty in dismounting due to the fact that the splines are tightly engaged cannot be caused. After improvement, the splines are convenient to mount and dismount since the spline taper fit portion can be loosened only by loosening the spline shaft tightening nuts and slightly knocking the cutting disc.
Description
Technical field
The invention belongs to field of agricultural machinery, particularly a kind of coupling arrangement that prevents the loosening tapering spline of cutter-head of machine for making furrows.
Background technique
Ditching machine is the ditching machine that a kind of and walking tractor matching are used, and can be arranged on before tractor or, help peasant to realize a kind of equipment of trench digging mechanization below.Ditching machine during in working order with off working state, usually there will be some problems below:
(1) splined: cutter-head of machine for making furrows diameter is large owing to being subject to, and have impact load, and often there is nut loosening, cause cutter axis spline and splined place, cutterhead sieve whirlpool loosening, cause cutter axis and cutterhead wheel whirlpool spline collision deformation, spline fitted is damaged and lost too early the function of passing on Gong.
(2) cutterhead dismounting: keyway cooperation coefficient is misfitted, the gap between keyway is unsuitable excessive, otherwise easily damages cutter axis; When ditching machine work, because keyway gap location very easily gets rusty and joins and use earth impurity, make cutterhead just be difficult in use for some time dismounting, do not utilize peasant's farm work, waste time and energy.
Summary of the invention
The object of the present invention is to provide be a kind ofly connected firmly, the coupling arrangement that prevents the loosening tapering spline of cutter-head of machine for making furrows of quick detachable, long service life.
The technical solution that realizes the object of the invention is:
A kind of coupling arrangement that prevents the loosening tapering spline of cutter-head of machine for making furrows, comprise cutter axis bearing support, nut, cutterhead splined shaft and wheel snail spline housing, cutterhead splined shaft is connected on cutter axis bearing support by fastening nuts, wheel whirlpool spline housing is arranged on cutterhead splined shaft periphery, and the spline fitted between cutterhead splined shaft and wheel whirlpool spline housing is tapering spline fitted.
The present invention compared with prior art, its remarkable advantage:
The present invention adopts spline fitted between cutter axis spline and cutterhead wheel whirlpool splined all to adopt tapering spline fitted.So greatly increase the friction factor of cutterhead splined shaft and wheel whirlpool spline fitted, when the nut of fastening splined shaft, cutter axis spline and cutterhead wheel whirlpool splined can not be become flexible, therefore splined section can be because of the loosening collision deformation that causes, can not make spline damage too early the urban district function of passing on Gong, more can not kill and be difficult to dismounting because of spline.Spline after improvement needs only loose splined shaft tightening nut, one strikes cutterhead gently, and spline taper fit part unclamps, so easy accessibility.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is partial structurtes enlarged diagram of the present invention.
Embodiment
A kind of coupling arrangement that prevents the loosening tapering spline of cutter-head of machine for making furrows of the present invention, comprise cutter axis bearing support 1, nut 2, cutterhead splined shaft 3 and wheel snail spline housing 4, cutterhead splined shaft 3 passes through nut 2 tight joints on cutter axis bearing support 1, wheel whirlpool spline housing 4 is arranged on cutterhead splined shaft 3 peripheries, and the spline fitted between cutterhead splined shaft 3 and wheel whirlpool spline housing 4 is tapering spline fitted.Tapering α between cutterhead splined shaft 3 and wheel whirlpool spline housing 4 is arranged on 0.5-7 degree.
Embodiment 1:
The coupling arrangement that prevents the loosening tapering spline of cutter-head of machine for making furrows as shown in Figure 1 and Figure 2 comprises cutter axis bearing support 1, nut 2, cutterhead splined shaft 3 and wheel snail spline housing 4, cutterhead splined shaft 3 is fastenedly connected on cutter axis bearing support 1 by nut 2, and wheel whirlpool spline housing 4 is arranged on cutterhead splined shaft periphery.It is 0.5 degree that cutterhead splined shaft and wheel snail spline housing are arranged to identical tapering α, be used for increasing cutterhead splined shaft 3 and the friction factor of taking turns whirlpool spline housing 4 fitting surfaces, in the time that ditching machine is worked, cutter axis spline and cutterhead wheel whirlpool splined can not be become flexible, therefore splined section can be because of the loosening collision deformation that causes, can not make spline damage too early the urban district function of passing on Gong, more can not kill and be difficult to dismounting because of spline.Spline after improvement needs only loose splined shaft tightening nut, one strikes cutterhead gently, and spline taper fit part unclamps, so dismounting and convenient.
Embodiment 2:
The coupling arrangement that prevents the loosening tapering spline of cutter-head of machine for making furrows of this enforcement comprises cutter axis bearing support 1, nut 2, cutterhead splined shaft 3 and wheel snail spline housing 4, cutterhead splined shaft 3 is fastenedly connected on cutter axis bearing support 1 by nut 2, and wheel whirlpool spline housing 4 is arranged on cutterhead splined shaft periphery.It is 7 degree that cutterhead splined shaft and wheel snail spline housing are arranged to identical tapering α, be used for increasing cutterhead splined shaft 3 and the friction factor of taking turns whirlpool spline housing 4 fitting surfaces, in the time that ditching machine is worked, cutter axis spline and cutterhead wheel whirlpool splined can not be become flexible, therefore splined section can be because of the loosening collision deformation that causes, can not make spline damage too early the urban district function of passing on Gong, more can not kill and be difficult to dismounting because of spline.Spline after improvement needs only loose splined shaft tightening nut, one strikes cutterhead gently, and spline taper fit part unclamps, so dismounting and convenient.
