Description
Technical field
The utility model relates to a kind of two-slices gear side set setting device, belongs to mechanical transmission fields.
Background technology
Geartransmission is a kind of transmission form most widely used in mechanical transmission, and its transmitting ratio is relatively accurate, and efficiency height, compact construction, reliable operation, the life-span is long.
When meshed transmission gear, in order to avoid because of the gear teeth rub sassafras heating expand and stuck, gap must be left between flank profil, this gap is called tooth side clearance, be called for short sideshake.
The existence of tooth side clearance can have influence on the stationarity of geartransmission, especially in the numerical control device of some precisions, if there is tooth side clearance, system being caused oppositely motion delay all to be made in instruction signal afterwards, the precision of processing units will be had a huge impact by this every time.
Practical novel content
The utility model is intended to provide one can eliminate tooth side clearance, avoids gear heating to expand stuck, it is to increase the stationarity of geartransmission and the two-slices gear side set setting device of precision simultaneously.
Two-slices gear side set setting device in this scheme, comprise the first thin slice gear and the 2nd thin slice gear, first thin slice gear is provided with circular projection, 2nd thin slice gear empty set is in circular projection, 2nd thin slice gear can around own axis but shaftless to degree of freedom, first thin slice gear is at least evenly equipped with two the first lugs, 2nd thin slice gear is evenly equipped with two lug identical with the first lug quantity, first lug and the 2nd lug are one right between two, first lug and the 2nd lug have all offered through hole, first lug is equipped with screw, screw is all provided with setting nut, screw is connected by extension spring with corresponding 2nd lug, when extension spring two ends are opened, extension spring will produce and draw direction opposite effect power.
The principle of work of the two-slices gear side set setting device in this scheme is: in geartransmission, in two straight tooth column gears engaged one is adopted conventional wide gear, another comprises the first thin slice gear in this scheme and the 2nd thin slice gear, 2nd thin slice gear can around own axis, when carrying out the assembling of gear, owing to having extension spring on the screw of the first thin slice gear and the 2nd lug, by rotating setting nut, screw is made to become big with the distance of corresponding 2nd lug, the extension spring that now screw connects with corresponding 2nd lug place will be in stretched state, owing to the tension force contrary with draw direction will be produced when extension spring two ends are opened, under the effect of extension spring tension force, 2nd thin slice gear is along own axis, reach the first thin slice gear and the object of the 2nd thin slice gear side set, relatively rotating of first thin slice gear and the 2nd thin slice gear, the side that the first thin slice gear will be made to be close to wide gear teeth groove, another side of wide gear is close to by 2nd thin slice gear.
The useful effect of the two-slices gear side set setting device in this scheme is: one of them gear in geartransmission adopts the mode become by two thin slice gear combination, arrange between two thin slice gears simultaneously and can make two thin slice gear extension springs in relative rotation, by regulating the length of extension spring, two thin slice gears can both sides with another wide gear teeth groove in geartransmission be contacted respectively respectively under the effect of extension spring, thus reach and eliminate tooth side clearance, simultaneously due to two thin slice gears all the time only side be close to wide gear, therefore heating in thin slice working gear process is also there will not be to expand and stuck phenomenon occurs, effectively improve stationarity and the precision of geartransmission.
Further, in order to make whole device uniform force, the lug of the first thin slice gear and the 2nd thin slice gear is equally distributed four.
Further, in order to make the 2nd thin slice gear shaftless to degree of freedom, being provided with card groove in circular projection, card groove is provided with for the snap ring to the 2nd thin slice gear axial limiting.
Further, in order to make in transmission process, setting nut can not shake, and at setting nut, place is equipped with set nut.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the longitudinal sectional drawing of the utility model embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: the first thin slice gear 1, the 2nd thin slice gear 2, first lug 3, the 2nd lug 4, extension spring 5, setting nut 6, set nut 7, screw 8.
Embodiment is substantially as shown in Figures 1 and 2: two-slices gear side set setting device, comprises the first thin slice gear 1, the 2nd thin slice gear 2, first lug 3, the 2nd lug 4, extension spring 5, setting nut 6, set nut 7 and screw 8.
First thin slice gear 1 is the hollow structure inside being with circular projection, it is evenly equipped with four threaded holes in the first thin slice gear 1 circumference, circular projection has been offered a card groove, in card groove, snap ring is installed, snap ring external diameter is greater than the external diameter of circular projection, is equipped with chamfering in the interior hole of the first thin slice gear 1 and the end face of circular projection.
The circular ring of perforate centered by 2nd thin slice gear 2, the hole empty set that 2nd thin slice gear 2 is offered by center is in the circular projection of the first thin slice gear 1, 2nd thin slice gear 2 side and the first thin slice gear 1 offset, another side and snap ring offset, owing to snap ring external diameter is greater than the external diameter of circular projection, therefore simultaneously shaftless to degree of freedom around own axis of the 2nd thin slice gear 2 can be made, four through holes have been offered at the 2nd thin slice gear 2 and the first thin slice gear 1 threaded hole corresponding position, first lug 3 coordinates through this through hole and its screw thread place with the threaded hole place of the first thin slice gear 1, first lug 3 installation, 2nd thin slice gear 2 circumference is also evenly equipped with and the threaded hole that four are staggered with through hole position, 2nd lug 4 threaded portion screws in this threaded hole place, 2nd lug 4 installation.
First lug 3 and the 2nd lug 4 have all offered through hole, it is equipped with screw 8 in the first lug 3 through hole, setting nut 6 and set nut 7 are installed at screw 8 place, the two ends of extension spring 5 are connected with the through hole of the 2nd lug 4 and the nut place of screw 8 respectively, the length making screw 8 stretch out lug when rotation setting nut 6 changes, now will cause the length variations of extension spring 5, under the effect of extension spring 5,2nd thin slice gear 2 rotates relative to the first thin slice gear 1, thus two thin slice gears are staggered, offset from the different sides of wide gear teeth groove respectively.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this. Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, it is also possible to make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented.
