Description
Technical field
The utility model relates to machinery field, specifically a kind of electric motor protecting structure.
Background technique
In magnesium slag production process, it is necessary first to be crushed to magnesium ore.Since magnesium nugget is larger, crocodile is generally used
Formula crusher is tentatively crushed, and is then further crushed with beater grinder.When using hammer mill, due to material
Volume is different, or even sometimes with other impurities, the biggish material of these volumes or the material containing harder impurity will cause hammer
The motor of formula crusher occur by outer power limit can not rotation phenomenon, i.e. " bored vehicle " phenomenon, phenomenon will cause motor and burn.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide the motors that one kind can solve " bored vehicle " phenomenon
Structure is protected, specific technical solution is as follows:
A kind of high purity magnesium ore crusher motor Anti-burnout device, motor output shaft are coaxially turned by positioning key with driving wheel
Dynamic, driving wheel is arranged in the through-hole of belt pulley；Driving wheel is cylinder, is matched on the inside of the outside of driving wheel and the through-hole of belt pulley
It closes；The driving wheel is disposed radially first positioning hole, and the first positioning hole is blind hole, and setting is fixed at the aperture of the first blind hole
Position ball positions and the first spring is arranged between ball and first positioning hole bottom；Second location hole is arranged radially along the belt pulley, second
The port setting slide plate of location hole abutted with driving wheel, the slide plate is towards the face of driving wheel and the outside cambered surface one of driving wheel
It causes；The back side of the slide plate and one end of second spring are fixed, and the other end of second spring and the side of adjustable plate are fixed, and are adjusted
The other side for saving plate is abutted with the bottom of adjusting bolt, and the end for adjusting bolt is tightened on screw hole on the side baffle ring of belt pulley
In.
The aperture of the second location hole is greater than the aperture of first positioning hole.
The utility model has the advantages that: using the rotary power of motor output shaft, crack motor output shaft by deadlock phenomenon,
Motor is protected not to be burned out.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is positioning ball force analysis figure.
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing, as shown, motor output shaft 1 passes through positioning key 2 and driving
Wheel 3 rotates coaxially, and driving wheel 3 is arranged in the through-hole of belt pulley；Driving wheel 3 is cylinder, the outside of driving wheel 3 and belt pulley
4 through-hole fit inside；The driving wheel 3 is disposed radially first positioning hole 6, and the first positioning hole 6 is blind hole, and first is blind
Setting positioning ball 9 at the aperture in hole 6, positions and the first spring 8 is arranged between ball 9 and 6 bottom of first positioning hole；Along the belt pulley 4
It is arranged radially second location hole 7, the port setting slide plate 10 of second location hole 7 abutted with driving wheel 3,10 direction of slide plate
The face of driving wheel 3 is consistent with the outside cambered surface of driving wheel；The back side of the slide plate 10 and one end of second spring 11 are fixed, and second
The other end of spring 11 and the side of adjustable plate 12 are fixed, and the other side of adjustable plate 12 is abutted with the bottom for adjusting bolt 13,
The end for adjusting bolt 13 is tightened in the screw hole on the side baffle ring 5 of belt pulley 4.
When to guarantee that positioning ball is retracted into first positioning hole, it is smoothly connected on the outside of slide plate 10 and driving wheel, and will not
It falls into first positioning hole, the aperture of the second location hole 7 is greater than the aperture of first positioning hole 6.
In the utility model, the elastic force of the second spring in second location hole is less than the bullet of the first spring in first positioning hole
Power, in this way, positioning ball will some be embedded in second location hole, therefore, the rotation of driving wheel can drive belt pulley
Rotation.
When encountering external force, belt pulley can not be rotated by locked, at this point, the output shaft of motor still rotates, the second positioning
The edge in hole and the contact point of positioning ball can give positioning one pressure F1 of ball, and the direction of the pressure is to pass through positioning from contact point
The centre of sphere of ball；The pressure is decomposed into horizontal pressure F2 and vertical F3, and positioning ball is pressed under the action of vertical force F3
In first positioning hole, thus it is guaranteed that driving wheel can be rotated with opposite pulleys, avoids motor " being suffocated " and burn.
It adjusts bolt to be adjusted the elastic force of the first spring, disengaging can be set and " suffocated " the external force situation of phenomenon, with
It is applicable in different materials.
