Detailed description of the invention
With reference to the accompanying drawings and the utility model will be further described in conjunction with the embodiments.
Stepless speed-regulating device of the present utility model can be applied in CK5116 vertical lathe gearbox.As shown in Figure 1, stepless speed-regulating device of the present utility model is primarily of compositions such as casing 1, first rotating shaft 2, second rotating shaft 3, the 3rd rotating shaft 4, shifting fork bar 5, first gear 6, second gear 7, the 3rd gear 8, duplicate gear 9, shift fork 10, belt pulley 11 and bevel gears 12.
Wherein, the first rotating shaft 2, second rotating shaft 3, the 3rd rotating shaft 4 and shifting fork bar 5 is parallel is located in casing 1, above-mentioned each axostylus axostyle is arranged in order in order.One end of first rotating shaft 2 is extended outside casing 1, and belt pulley 11 is fixed on this end.Belt pulley 11 is connected with belt, and belt is then driven by variable-frequency motor and rotates, and rotates to drive the first rotating shaft 2.One end of 3rd rotating shaft 4 is extended outside casing, and bevel gear 12 is fixed on this end, and bevel gear 12 engages with the main shaft of workbench, drives worktable rotary.During specific works, variable-frequency motor, by belt drive first axis of rotation, carries out transmission through the gear be located in the first rotating shaft, the second rotating shaft, the 3rd rotating shaft, and then orders about the 3rd rotating shaft rotation, drives worktable rotary when the 3rd rotating shaft rotates.
First gear 6, second gear 7, the 3rd gear 8 and duplicate gear 9 are for realizing the transmission between three groups of rotating shafts.First gear 6 is fixed in the first rotating shaft 2, is positioned at casing 1.Second gear 7 and the 3rd gear 8 are fixed in the second rotating shaft 3.Second gear 7 and the first gear 6 intermesh, and the second rotating shaft 3 can be driven to rotate when the first rotating shaft 2 is rotated.In order to reach good transmission effect, the quantity of the first gear 6 and the second gear 7 is generally set to two groups, and as shown in the figure, the position of close casing 1 both sides sidewall in the first rotating shaft 2 and the second rotating shaft 3 is located at respectively by two groups of gears, and two groups of gears engage respectively.
3rd gear 8 is positioned at the middle part of the second rotating shaft 3, and its diameter is less than the diameter of the second gear 7.Duplicate gear 9 is fixed in the 3rd rotating shaft 4, and this duplicate gear 9 can move axially along the 3rd rotating shaft 4.The profile of tooth of duplicate gear 9 both sides is mated with the second gear 7 and the 3rd gear 8 respectively, when duplicate gear 9 moves (for left in figure) to the second gear 7, duplicate gear 9 can engage with the second gear 7, when moving (for the right in figure) to the 3rd gear 8, duplicate gear 9 can engage with the 3rd gear 8.Under two kinds of different states, the gearratio between the second rotating shaft 3 and the 3rd rotating shaft 4 can change, respectively the state of corresponding high-grade speed (40-160 rev/min) and geared-down speed (5-40 rev/min).When being in different shelves speed, variable-frequency motor frequency can be changed to realize the adjustment of arbitrary speed in scope.
Shifting fork bar 5 and shift fork 10 are for driving duplicate gear 9 displacement.Shifting fork bar 5 is parallel with the 3rd rotating shaft 4, and it can carry out axial displacement under the effect of oil cylinder 13.Shift fork 10 is fixed between shifting fork bar 5 and duplicate gear 9, and when shifting fork bar 5 moves, duplicate gear 9 can follow action, thus the second gear 7 engagement and and the 3rd gear 8 engagement between switch.
It is many that the utility model has abandoned old-fashioned gearbox gear, oil cylinder is many, baroque shortcoming, the structure of casing is simple, only have 7 gears and a shift fork in whole casing, cost saved greatly by more old-fashioned gearbox, decreases the difficulty of assembling, more can make workbench from before step speed regulation become the present setting that can realize any rotating speed, make operator can by their desirable rotating speed to carry out the processing of workpiece.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
