The utility model knows to have following advantage through a large amount of tests: variable speed operation is simple, quick; do not need during laborsaving, speed change to shut down; can realize infinitely variable speeds, speed change is accurate, and the self-locking after the speed change is effective; can realize trickleer speed change; can in maximum slewing range, satisfy the requirement of permanent power transmission, can realize continuous change and uninterrupted speed change, and rotating speed is accurately shown; speed-regulating hand wheel can speed governing in greater than 360 degree scopes, low cost of manufacture etc.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation, accompanying drawing 2 is that speed governing axle 9 structure for amplifying schematic diagrames are mainly illustrated speed regulating structure in the accompanying drawing 1, accompanying drawing 3 is A-A section structure for amplifying schematic diagrames in the accompanying drawing 2, and accompanying drawing 4 is that K is to structural representation in the accompanying drawing 2, and accompanying drawing 5 is digital display structural representations.
The specific embodiment:
19 is bases among the figure, column 18 is installed on the base 19, installment work platform 17 and casing 16 on the column 18, power transmission shaft 2 and main shaft 24 are installed in casing 16 tops, the power of power transmission shaft 2 is by motor 1 input, motor driving wheel 4 and motor fixed wheel 5 are installed on the power transmission shaft 2, main shaft fixed wheel 12 and main shaft driving wheel 11 are installed on the main shaft 24, speed governing axle 9 is installed between power transmission shaft 2 and main shaft 24, thread segment 31 is set on the speed governing axle 9, thread segment 31 on the speed governing axle 9 matches with screwed hole 25 on the bearing block 10, and bearing block 10 is installed on the main shaft 24 simultaneously, and speed governing axle 9 is by the speed-regulating hand wheel driven rotary.Driven wheel of differential 20 is installed in speed governing axle 9 lower ends, driven wheel of differential 20 and drive bevel gear 23 engagements, and speed-regulating hand wheel 15 is fixedlyed connected with drive bevel gear 23.Offer screwed hole 25 and light face 26 on the bearing block 10.Groove 27 is offered in the edge of main shaft fixed wheel 12.Digital display sensor 13 is installed at edge at main shaft fixed wheel 12, and digital display sensor 13 is connected with printed substrate 30 by lead 28, and digital display screen 29 is connected with printed substrate 30.Switch enclosure 14 is installed on the casing 16, digital display screen 29 is installed on the switch enclosure 14.
9 on speed governing axle of the present utility model rotates, do not do and move up and down, the thread segment 31 that is provided with on it can well be realized the self-locking after the speed governing, and can realize the adjustment of trickle rotating speed, make the rotation of speed governing axle 9 can have multiple scheme to realize, for example: can directly the speed governing handle be installed, but this structure can not guarantee handling safety in the lower end of speed governing axle 9.Disclosed structure is more reasonable in the present embodiment, and it can guarantee easy-to-operate.When the utility model needs speed governing, rotate speed-regulating hand wheel 15, driving speed governing axle 9 by drive bevel gear 23 and driven wheel of differential 20 rotates, because the screwed hole 25 on the bearing block 10 cooperates with speed governing axle 9, but, the rotation impeller-hub bearing 10 of speed governing axle 9 moves up and down so doing, and then the belt 7 and the contact diameter of main shaft driving wheel 11 and main shaft fixed wheel 12 are changed, belt 7 changes with the contact diameter of motor driving wheel 4 and motor fixed wheel 5 simultaneously, thereby reaches the purpose that makes main shaft 24 rotation speed change.The rotation of the speed-regulating hand wheel 15 in the utility model structure is continuous, the rotation of speed governing axle 9 also is continuous, moving up and down of speed governing axle 9 impeller-hub bearings 10 also is continuous, the variation of the drive diameter of the belt that contacts with moving fixed wheel also is continuous, so rotating speed of the present utility model can be realized continuous continual speed change, real realization infinitely variable speeds realizes the speed change greater than 360 scopes.Circuit in the utility model rotating speed display structure all adopts known technology to finish, and 3 is springs among the figure, and the 6th, protective cover, the 8th, supporting seat is because main improvement of the present utility model is infinitely variable speed structure, so known technology is not described in detail in detail.
