Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 4, the utility model discloses a belt switching wheel device, including first belt pulley 1, second belt pulley 2, drive shaft 3 and dial 4, first belt pulley 1 sets up on drive shaft 3 with second belt pulley 2 relatively to rotate through bearing and drive shaft 3 respectively and be connected, dial 4 setting of dish between first belt pulley 1 and second belt pulley 2, the both sides of dial 4 of dish all are equipped with first separation and reunion tooth 5, all be equipped with on first belt pulley 1 and the second belt pulley 2 rather than corresponding the first separation and reunion tooth 6 of the first separation and reunion tooth 5 matched with of side. In order to reduce the processing cost and be convenient for maintain, the utility model discloses a drive shaft 3 is equipped with the cross-section and is regular polygon's dial plate erection section 31, dial plate 4 be equipped with the regular polygon mounting hole 41 of dial plate erection section 31 looks adaptation, dial plate 4 and pass through mounting hole 41 slip cap is located dial plate erection section 31 is last to be connected with dial plate erection section 31 transmission.
The cross-section of stirring dish installation section 31 can be square, regular pentagon, regular triangle, regular hexagon etc. and the stability that processing convenience and transmission are connected is taken into account comprehensively, the utility model discloses well preferred adoption regular hexagon. The drive shaft 3 may be a motor spindle or a separately provided drive shaft.
Mounting hole 41 and dial dish installation section 31 looks adaptation, specifically speaking, dial dish installation section 31 is regular pentagon, and corresponding mounting hole 41 also is regular pentagon, dials dish installation section 31 and is regular hexagon, and corresponding mounting hole 41 also is regular hexagon to this analogizes, and the aperture of mounting hole 41 specifically only needs to be slightly bigger than the external diameter of dialling dish installation section 31 to it slides and can not rotate relatively to make to dial along dialling the dish installation section and be accurate.
The utility model discloses a belt conversion takes turns device the same with current belt conversion takes turns device's theory of operation to drive first belt pulley 1 as an example: when power switches, to 1 direction slip of first belt pulley dial driving disk 4, make and dial driving disk 4 towards first separation and reunion tooth 5 of first belt pulley 1 and the cooperation of the second separation and reunion tooth 6 on the first belt pulley 1, so, the accessible is dialled driving disk 4 and is driven first belt pulley 1 and rotate when the drive shaft rotates. If need drive second belt pulley 2, the backward slip dials driving disk 4 until to face the first separation and reunion tooth 5 of second belt pulley 2 and the cooperation of second separation and reunion tooth 6 on the second belt pulley 2, at this moment, the first separation and reunion tooth 5 towards first belt pulley 1 and the second separation and reunion tooth 6 on the first belt pulley 1 break away from the cooperation, so, accessible dial driving disk 4 drives second belt pulley 2 and rotates when the drive shaft rotates. Because agricultural machine service environment is abominable, the dust is great on every side, and the frequency of use at most agricultural machinery of agricultural machinery trade is lower relatively, and the frequency that needs to carry out the power switching is also lower, adopts spline transmission's structure between stirring dish 4 and the drive shaft 3, and the dust is very easily piled up in the keyway, and the clearance is very inconvenient, is not convenient for maintain. The utility model discloses set up the cross-section in the drive shaft and be regular polygon stir a set installation section, stir a set 4 and stir a set installation section and realize slip and transmission cooperation through polygon mounting hole 41, satisfied the torque transmission requirement, it is not only more convenient to stir the processing of dish and drive shaft, and the surface of drive shaft does not have less slot, and the dust is difficult for piling up, even there is a small amount to pile up the clearance also convenient, therefore the maintenance of being more convenient for. In addition, the structure can make the outer diameter of the driving shaft smaller, and save more materials.
The first clutch tooth 5 can be welded or bolted to the dial plate. The utility model discloses in, first separation and reunion tooth 5 by set up in the periphery of stirring dish 4 and with stirring dish 4 extension 42 bending type that structure as an organic whole. The processing of stirring dish is not only convenient like this, and first separation and reunion tooth 5 also better with the connectivity between stirring dish 4.
In the present invention, the side of the end of the first clutch tooth 5 is provided with an inclined guide surface 51. When the dial plate 4 is not slid in place, that is, the first clutch teeth 5 and the second clutch teeth 6 are not completely engaged, since the side surface of the end portion of the first clutch teeth 5 is provided with the inclined guide surface 51, and the second clutch teeth 6 are engaged with the guide surface 51, the first clutch teeth 5 can be moved toward the second clutch teeth 6 engaged therewith by applying a force to the first clutch teeth along the axial direction of the drive shaft 3 through the guide surface 51, so that the first clutch teeth 5 and the second clutch teeth 6 are completely engaged. Above-mentioned structure can avoid stirring 4 circumstances that can not switch to appear, and stirs 4 difficult break away from the belt pulley of dish. The dial plate 4 can be provided with a jacking screw 7 matched with the driving shaft 3 as required so as to lock the relative position of the dial plate 4.
The diameters of the first pulley 1 and the second pulley 2 may be equal or different, and in practice, one of the pulleys is usually larger in diameter. For the belt pulley with larger diameter, the conventional forming mode comprises casting forming or sheet metal spinning and then stamping forming. The second clutch teeth 6 may be welded or bolted to the side or periphery of the pulley, but this process is complicated. When the outer diameter of the first pulley 1 is larger than the outer diameter of the second pulley 2, it is preferable that the second clutch tooth 6 on the first pulley 1 is formed by opening a hole on the web of the first pulley 1. Therefore, the second clutch teeth 6 can be conveniently formed at the same time when the first belt pulley is formed, and the production process of the first belt pulley can be simplified. In addition, the above structure can reduce the weight of the first pulley 1, and the second clutch teeth 6 are not easy to deform.
For the second clutch teeth 6 of the second belt pulley 2, preferably, the second clutch teeth are arranged on the periphery of the second belt pulley 2, so that compared with the second clutch teeth arranged on the side surface of the second belt pulley 2, under the condition that the stress of the first clutch teeth is the same, the torque which can be provided by the toggle plate with the above structure to the second belt pulley 2 through the first clutch teeth is larger.
The utility model discloses in, drive shaft 3 is the transmission shaft that sets up alone, is connected with motor spindle for its convenience, be equipped with in the drive shaft 3 along the centre bore 32 of its axis extension for the cover is established on motor spindle, the inner wall of centre bore 32 is equipped with the through-hole in order to form keyway 33, is used for installing the parallel key. The inner wall of centre bore 32 is equipped with the through-hole in order to form keyway 33, and the installation of the flat key of easy to assemble, and be convenient for fix drive shaft 3 on motor spindle (the flat key is installed the back welding can on drive shaft 3).
