Description
Technical field
The utility model relates to a kind of blender transmission gear dependency structures of building machinery industry, are specifically related to one kind
The belt of blender transmission gear is from tensioning apparatus.
Background technique
In the prior art, in the transmission device in building machinery, for using belt drive system, general use is electricity
The directly fixed mode of machine, by the screw rod of manual adjustment motor, is laterally dragged after belt uses aging, transmission system to loosen
Dynamic motor, to adjust the elasticity of belt, this structure artificial maintenance cost is high, safety is poor, can not be adjusted in real time,
It is run for a long time in the case where flying tensioning state, causes belt service life short.
Existing belt stretcher is all utilized in belt middle and increases tensioning wheel, will adjust and open after belt slack
The position of bearing up pulley either manually adjusts and automatically adjusts to make belt tension, due to the position limitation and tensioning of tensioning wheel
The limitation for taking turns structural design space, causes belt tension effect bad, working condition can not be stablized, and belt service life is short
Defect.
Based on this, a kind of stable working state, the long belt tensioning structure of belt service life becomes the industry and needs to solve
Certainly the technical issues of.
Summary of the invention
The utility model provides a kind of belt from tensioning apparatus, which can be by adjusting motor supporting plate to make belt
Tensioning, stable structure.Medium-voltage Motor supporting plate is pressed using holddown spring from tensioning apparatus simultaneously, it can be in real time to the tensioning of belt
Regulated and controled, to guarantee the normal operation of belt drive system, stable working state improves belt service life, enhancing
Equipment use reliability.
The utility model provides a kind of belt from tensioning apparatus, has cylinder and motor supporting plate, the motor supporting plate passes through
Pin shaft is fixed on the cylinder, and be that the motor supporting plate is pivotable is connected with the cylinder, the end of the motor supporting plate
Portion is connected on the cylinder by screw rod, is provided with holddown spring on the screw rod, makes the electricity by the holddown spring
Machine pressing plate is pressed towards the cylinder direction, is used for automatic tensioning belt.
As one embodiment of the present invention, also there is speed reducer, the speed reducer is fixed on reducer pedestal, described to subtract
Fast base is fixed on the cylinder.
As one embodiment of the present invention, big belt pulley, the belt and the great Pi are provided on the speed reducer
Belt wheel connection.
As one embodiment of the present invention, motor is fixed on the motor supporting plate, the motor is equipped with belt lace
Wheel, the belt are connect with the small belt pulley.
As one embodiment of the present invention, the belt is V belt.
The belt of the utility model is simple from tensioning device structure, and good operating stability, belt service life significantly improves.
Detailed description of the invention
Fig. 1 is belt of the invention from tensioning device structure schematic diagram；
The meaning respectively marked in figure is as follows:
1- big belt pulley, 2- V belt, 3- small belt pulley, 4- motor, 5- spring, 6- screw rod, 7- motor supporting plate, 8- pin
Axis, 9- speed reducer, 10- reducer pedestal, 11- cylinder.
Specific embodiment
The belt of the utility model is described in detail from tension structure with reference to the accompanying drawing:
As shown in Figure 1, the belt of the utility model includes cylinder 11 from tensioning apparatus, motor supporting plate is provided on cylinder 11
7, motor supporting plate 7 is fixed on cylinder 11 by pin shaft 8, makes motor supporting plate 7 is pivotable to be connected with cylinder 11, while electricity
The one end of machine supporting plate 7 is connected on cylinder 11 by screw rod 6, and holddown spring 5 is provided on screw rod 6, passes through holddown spring 5
Pressing presses motor supporting plate 7 towards cylinder direction, so that motor supporting plate be made to rotate around pin shaft.
Reducer pedestal 10 is additionally provided on cylinder 11, reducer pedestal 10 is fixedly connected with cylinder 11, solid on reducer pedestal 10
Surely there is speed reducer 9, speed reducer 9 is equipped with belt pulley 1.Motor 4 is fixed on motor supporting plate 7, motor 4 drives belt pulley 3, belt
It is attached between wheel 1 and belt pulley 3 using belt 2.Preferably, the belt 2 of the utility model selects V belt.
The specific work process of the utility model are as follows: motor supporting plate 7 is suppressed to cylinder direction by holddown spring 5, makes electricity
Machine supporting plate 7 drives motor 4 fixed thereon to can be rotated along clockwise direction stress shown in Fig. 1, is connected in small belt pulley 3 and great Pi
Thus auto-tensioning is ground with guaranteeing normal operating conditions as V belt uses V belt 2 on belt wheel 1 for a period of time
After damage and stretching, the elastic force of holddown spring 5 can suppress automatically motor supporting plate 7, rise so that V belt be stretched, remain and set
Standby steady operation.
It is emphasized that the utility model above example is merely to illustrate the working principle of the utility model, for
The structure of the utility model does not do limitation in any form, all according to the simple of the technical essence of the utility model progress
Modification, equivalent variations and modification, are still within the scope of the technical solutions of the present invention.
