Further scheme is: described the first axle sleeve is provided with through hole, is provided with tapped hole in described the second axle sleeve, and described the first axle sleeve and the second axle sleeve are fixed by the screw that passes through hole and tapped hole.
further scheme is: also comprise the first support ring and the second support ring, described the first support ring is set on the first axle sleeve, described the second support ring is set on the second axle sleeve, described gear is provided with first step and second step, described the first axle sleeve is provided with the first table top and the second table top, described the second axle sleeve is provided with the 3rd table top and the 4th table top, the first table top on described the first axle sleeve and the upper end of the first support ring connect, the lower end of described the first support ring and the first step on gear connect, the second table top on described the first axle sleeve and the first step on gear connect, the 3rd table top on described the second axle sleeve and the upper end of the second support ring connect, the lower end of described the second support ring and the second step on gear connect, the 4th table top on described the second axle sleeve and the second step on gear connect.
Further scheme is: described the first support ring and the second support ring are provided with circular projection circle near gear side.
The beneficial effects of the utility model are: due to a kind of gear shaft of pneumatic actuator new structure, comprise the first axle sleeve, the second axle sleeve and the inner gear that is provided with cavity, it is inner that described the first sleeve head is arranged on gear one end, it is inner that described the second sleeve head is arranged on the gear the other end, and described the first axle sleeve and the second axle sleeve symmetric design can be replaced use mutually.Dismounting when pneumatic actuator need to reverse like this, only need to adjust the cylinder upper-lower position, no matter the counter-rotating of pneumatic actuator just can be realized toward which direction upset in the position that is arranged on the first axle sleeve of gear one end and the second axle sleeve that is arranged on the gear the other end.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is a kind of embodiment's of gear shaft of a kind of pneumatic actuator new structure of the utility model sectional view.
Embodiment
As shown in Figure 1, a kind of specific embodiment of the gear shaft of a kind of pneumatic actuator new structure of the utility model: a kind of gear shaft of pneumatic actuator new structure, comprise the first axle sleeve 1, the second axle sleeve 2 and the inner gear 3 that is provided with cavity, it is inner that described the first axle sleeve 1 head is arranged on gear 3 one ends, it is inner that described the second axle sleeve 2 heads are arranged on gear 3 the other ends, and described the first axle sleeve 1 and the second axle sleeve 2 symmetric designs can be replaced use mutually.Dismounting when pneumatic actuator need to reverse like this, only need to adjust the position of piston, no matter the second axle sleeve 2 that is arranged on the first axle sleeve 1 of gear 3 one ends and is arranged on gear 3 the other ends just can be realized the counter-rotating of pneumatic actuator toward which direction upset.
