Detailed description of the invention
Embodiment 1:
The present embodiment provides a kind of reel catch gear, as shown in Figure 1, comprise the output shaft 1 controlled by power input link 7 by propulsion source 8, described output shaft 1 vertically runs through the center of a fixing contrate gear 3, and fixing contrate gear 3 is fixed on output shaft 1, the fluted disc face vis-a-vis of fixing contrate gear 3 is provided with a sliding end face fluted disc 4, sliding end face fluted disc 4 is provided with and passes but the passage do not contacted with output shaft 1 for output shaft 1, sliding end face fluted disc 4 is movably arranged in frame 6, sliding end face fluted disc 4 is connected to actuating device 2, described actuating device 2 drives sliding end face fluted disc 4 along the axial motion of output shaft 1.
This structure of the present embodiment, output shaft 1 is driven to rotate by propulsion source 8 by power input link 7, in the process of rotating, sliding end face fluted disc 4 is in position as shown in Figure 1, when needs carry out drag, when output shaft location, actuating device 2 starts action, drive sliding end face fluted disc 4 along the axial motion of output shaft 1 by actuating device 2, namely in FIG, actuating device 2 drives sliding end face fluted disc 4 to move straight up, the fixing contrate gear 3 on sliding end face fluted disc 4 and output shaft 1 is finally made to be meshed into one, brake load, external impact dynamic changes process is in frame 6, reach the reliable locating effect of output shaft 1.
Fixing contrate gear 3 in the present embodiment and sliding end face fluted disc 4, can adopt close point of contrate gear, and like this when accurately locating, the precision of close point, higher than positioning precision, can realize accurate location.
During release output shaft, actuating device 2 drives sliding end face fluted disc 4 to depart from fixing contrate gear 3.Also according to structure needs, can will fix contrate gear 3 and sliding end face fluted disc 4 transposition, the slip drive member structure of cooperation does corresponding change.
This structure of the present embodiment, adopts the fine and closely woven fluted disc divided equally to carry out braking or braking, overcomes conventional brake friction braking distance, the shortcoming of brake lining quick abrasion, and brake area is large, and brake contact face unit pressure is little, and the life-span is long.
Embodiment 2:
On the basis of embodiment 1, the present embodiment is further described, in the present embodiment, sliding end face fluted disc 4 comprises the fluted disc face relative with fixing contrate gear 3 and is positioned at this center, fluted disc face and the tubular conduit of for output shaft 1 passing vertical with fluted disc face, this tubular conduit overcoat has spline component 5, and sliding end face fluted disc 4 is arranged in frame 6 by spline component 5.Wherein, spline component 5 is spline or feather key, and it is fixing, axially movable that sliding end face fluted disc 4 completes circumference by spline component 5.
From embodiment 1, this structure braking of the present invention is leaned on: fixing contrate gear 3 and sliding end face fluted disc 4 engage each other, and by brake load, external impact dynamic changes process in frame or casing, reach the reliable locating effect of output shaft.So sliding end face fluted disc 4 must possess circumferential static, axially movable feature, in the present embodiment, spline component 5 is spline or feather key, the axis of Huajian herein along output shaft 1 is arranged, namely this function can be realized simply, spline makes sliding end face fluted disc 4 restricted in circumferential direction, the spline direction motion that can only axially arrange, such axial motion realizes the engagement of fixing contrate gear 3 and sliding end face fluted disc 4 and separates, the braking of sliding end face fluted disc 4 circumference makes brake load, external impact load is by spline component 5(spline or feather key) be delivered in frame 6, reach the reliable locating effect of output shaft.
In the present embodiment, fixing contrate gear 3 be one complete discoid, the fluted disc face of sliding end face fluted disc 4 is complete circle or fan-shaped.Complete circle or fan-shaped can realization are braked with engaging of fixing contrate gear 3, sliding end face fluted disc 4 braking effect of complete circle is relatively good, and although fan-shaped sliding end face fluted disc 4 effect does not have the good braking effect of complete circle, but saving material, and braking effect is also more or less the same with the braking effect of complete circle, the brake of output shaft snap catch, the pinpoint effect of position of output axle all can be obtained.
Embodiment 3:
As can be seen from above-mentioned two embodiments, in the process of drag, a crucial action is had to be, actuating device 2 drives sliding end face fluted disc 4 along output shaft 1 axial motion, in the present embodiment, in order to make sliding end face fluted disc 4 action reposefully, actuating device 2 has multiple, be uniformly distributed around output shaft 1, multiple actuating device 2 is connected with sliding end face fluted disc 4 respectively.Like this, the action simultaneously of multiple output shaft 1, because it is evenly distributed on around output shaft 1, so the power that multiple actuating device 2 pairs of sliding end face fluted discs 4 apply is also relatively average, can make sliding end face fluted disc 4 move reposefully and there will not be deflection.
Actuating device 2 can be oil cylinder or connecting rod sliding york, such as enter the cylinder structure shown in 1, sliding end face fluted disc 4 is connected to by the piston rod of oil cylinder, urge piston rod movement by also pressure and then drive sliding end face fluted disc 4, such as connecting rod sliding york again, a transmission in pure physical construction, concrete structure is widely used, does not explain at this; Power input link 7 is belt wheel or gear or sprocket wheel, and propulsion source 8 is transmission or motor, and this composition of sample can add that motor forms an independent mechanism, also can be installed to the transmission position of other mechanisms, as brake portion.
In sum, this reel catch gear of the present invention, one group of end-tooth Meshing Pair is adopted to coordinate the structure of feather key, reach the brake of output shaft snap catch, the pinpoint object of position of output axle, under short distance braking, heavy shock loads, need position of output axle accurately, reliable location when, there is good result of use.
More than exemplifying is only to casehistory of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.The parts that the present embodiment does not describe in detail and structure belong to the well-known components of the industry and common structure or conventional means, do not describe one by one here.
