Abstract
The utility model belongs to the field of machinery, poor to current rotary motion conversion linear motion's device stability and a convert rotary motion to in linear motion's device that provide. Including box, worm wheel, worm and output shaft, the worm wheel is connected with the worm -drive, and worm axle and the actuating mechanism transmission of worm are connected, connects an eccentric wheel on the worm wheel, is equipped with the thrust unit who promotes output shaft axial displacement on the eccentric wheel. The utility model discloses simple structure drives the eccentric wheel with output axial motion through the gear and realizes for the axial motion speed stability more of output, and the regulation of speed is convenient, and the eccentric distance of stroke accessible transform eccentric wheel realizes.
Description
Technical field
The utility model belongs to mechanical field, particularly relates to a kind of device rotary motion being converted to straight line motion.
Background technique
Existing device rotary motion being converted to straight line motion is all generally realized by gear driven tooth bar, this structure needs to enable output automatic back-and-forth just need gear to realize clockwise and anticlockwise, need like this to change drive unit turn to realize, drive unit is easily damaged, poor continuity.
Model utility content
The utility model object is a kind of device rotary motion being converted to straight line motion provided for the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of device rotary motion being converted to straight line motion, comprise casing, worm gear, worm screw and output shaft, worm gear is connected with worm drive, and worm shaft and the driving mechanism of worm screw are in transmission connection, worm gear connects an eccentric wheel, eccentric wheel is equipped with the pushing device promoting output shaft axial displacement.
Described pushing device is needle bearing.
Output shaft is provided with the pushing tow face for pushing device pushing tow.
Pushing tow face is the shaft shoulder of output shaft both sides.
Distance between two shaft shoulders is greater than the diameter of pushing device movement locus.
The beneficial effects of the utility model: the utility model structure is simple, output terminal axial motion is realized by gear driven eccentric wheel, make the axial motion speed of output terminal more stable, and speed speed is easy to adjust, stroke is by converting eccentric throw of eccentric to realize.
Accompanying drawing explanation
Fig. 1 is the first visual angle sectional view of the present utility model;
Fig. 2 is the second visual angle sectional view of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment one
As depicted in figs. 1 and 2, a kind of device rotary motion being converted to straight line motion, comprise casing 1, worm gear 2, worm screw 3 and output shaft 4, worm gear is arranged on a stationary axle 7, and stationary axle is fixed on casing, between stationary axle 7 and worm gear, be provided with bearing, worm gear is connected with worm drive, worm shaft and the driving mechanism of worm screw are in transmission connection, and worm gear connects an eccentric wheel 5, eccentric wheel are equipped with the pushing device 6 promoting output shaft axial displacement.Driving mechanism drives worm screw to rotate, and worm screw drives worm gear wheel again, and eccentric wheel is followed worm gear and rotated together, and thus pushing device moves in a circle around the center of worm gear, and described pushing device is needle bearing.Output shaft is provided with the pushing tow face for pushing device pushing tow.Pushing tow face is the shaft shoulder of output shaft both sides.Distance between two shaft shoulders is greater than the diameter of pushing device movement locus.Pushing device ceaselessly can touch the shaft shoulder of output shaft both sides while moving in a circle, and time pushing device turns to the shaft shoulder near output shaft front end, pushing device continues the motion of movement progress output shaft forward end; When pushing device turns near output shaft rear end time, pushing device continues movement progress output shaft and moves to the back-end.
Embodiment two
A kind of device rotary motion being converted to straight line motion, comprise casing, worm gear, worm screw and output shaft, worm gear is connected with worm drive, and worm shaft and the driving mechanism of worm screw are in transmission connection, worm gear connects an eccentric wheel, eccentric wheel is equipped with the pushing device promoting output shaft axial displacement.Described pushing device is needle bearing.Output shaft is provided with the pushing tow face for pushing device pushing tow.Pushing tow face is the catch be arranged on output shaft.Distance between two catch is greater than the diameter of pushing device movement locus.The present embodiment principle is identical with embodiment, has not been described in detail at this.
If the utility model wants that the movement velocity changing output terminal has two kinds of methods, first is the size by changing worm gear, and second is the rotating speed changing input end.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
