The purpose of this utility model is the shortcoming at the above, is structurally improved, and an a kind of movable teeth rack employing tube beam type is provided and is designed to mouse cage inserted type structure; Adopt the squirrel-cage shaped roller type active-tooth transmission of the roller of full rolling structure.
Technical characteristics of the present utility model is: squirrel-cage shaped roller type active-tooth transmission is made of shock wave device, central gear and oscillating tooth component-assembled, it is characterized in that: the movable teeth rack of oscillating tooth parts is designed to the freely-supported beam type; Movable teeth rack is made of the oscillating tooth support body and the dummy slider at two ends, is provided with circumferentially uniform groove on the oscillating tooth support body of two ends, is equipped with dummy slider in groove, constitutes mouse cage shape, is equipped with the roller of full rolling structure in the circumferentially uniform radially guide groove of movable teeth rack.Roller constitutes (also can be special rolling bearing or both combinations) by axle with two kinds of different cylindrical body covers of diameter, the oscillating tooth support body of movable teeth rack one end, not only be supporting but also be load balancing mechanism, the oscillating tooth support body of the other end is with lower velocity shaft or directly make integral body or by key connecting (also can directly connect with the shaft extension of working machine), also can link with support; The form of the composition of shock wave device is various, and its rotary arm bearing can be common roller bearing or deep groove ball bearing, also can be the rolling bearing overcoat shock wave ring of no outer ring; Eccentric bushing can connect with key and high speed shaft, also can be directly and high speed shaft make an integral body, also can be without high speed shaft direct and prime mover shaft extension link; Eccentric bushing constitutes one group by two eccentric discs by 180 ° of direction configurations, also can be with two or more sets side by side to strengthen bearing capacity; The internal tooth corridor of central gear is conjugate curve, also can add straight line with circular arc and substitute; Complete machine can be made the plural serial stage form to enlarge slewing range.
Advantage of the present utility model: the movable teeth rack of freely-supported beam type has improved force-bearing situation, and load balancing mechanism has guaranteed the realization of multiple tooth meshing condition, thereby has improved bearing capacity; The radially guide groove of movable teeth rack is made of dummy slider, and dummy slider is independently processed, and easily realizes groove face requirement hardness height, the requirement that roughness is low, has solved the radially problem of guide groove processing difficulties of movable teeth rack; The slippage composition of roller in the movable teeth rack guide groove of full rolling structure reduces greatly, reduced frictional loss, transmission efficiency improves, wearing and tearing reduce, and the life-span increases, and generalization degree height, low, the compact integral structure of cost, in light weight, cost is low, the various needs that can adapt to various mechanical transmission of structural type.
Test simultaneously through a kind of embodiment to a kind of embodiment of the present utility model and CN2110744U, efficient of the present utility model exceeds 7 percentage points than CN2110744U, and the short-term overload capacity can reach more than 200% of load rating; Impulsive load reaches 400% o'clock of load rating, and indivedual rollers are just destroyed.
Now be further described in conjunction with a kind of embodiment of the present utility model (Fig. 1):
Fig. 1 is the structural representation of squirrel-cage shaped roller type active-tooth transmission;
Fig. 2 is the roller structure schematic representation of squirrel-cage shaped roller type active-tooth transmission.Fig. 2 a is the pattern of sliding bearing; Fig. 2 b is the special bearing pattern; Fig. 2 c is both combination forms.
With reference to accompanying drawing 1, eccentric bushing 2 is sleeved on the high speed shaft 1 by key, and eccentric bushing 2 cylindricals are set with rotary arm bearing 3 and constitute shock wave device.Central gear 5 has the internal tooth of conjugate curve tooth corridor, the movable teeth rack parts are made up of roller 4 and movable teeth rack 6, movable teeth rack is assembled by the oscillating tooth support body and the dummy slider at two ends, the oscillating tooth support body at movable teeth rack two ends is provided with circumferentially uniform groove, in groove, embed dummy slider through the grinding of quenching, constitute circumferentially uniform radially guide groove, movable teeth rack likeness in form mouse cage, two supports is on support, roller is radially radially rolling shifting movement in the guide groove, the oscillating tooth support body of one end plays the load balancing mechanism effect, and the oscillating tooth support body and the lower velocity shaft of the other end are linked to be an integral body.Shock wave device is contained in the movable teeth rack inner chamber, and an end bearing is on support, and on the other end supporting oscillating tooth support body at one end, central gear is enclosed within the peripheral of oscillating tooth parts and is fixed on the support.
After motion (power) is by high speed shaft 1 input, formed two high pair of the outer ring by larger-diameter cover in the middle of on the roller 4 and rotary arm bearing 3 and the internal tooth corridor of central gear 5, to move (power) pass to central gear 5, meanwhile, one of two ends group of cover on the roller than minor diameter, in the radially guide groove of movable teeth rack 6, radially roll and move, and will move (power) passes to movable teeth rack 6, movable teeth rack rotates and the conversion of the speed of realization thereby drive, because the oscillating tooth support body of a lower velocity shaft and an end is an integral body, so motion (power) is promptly exported by lower velocity shaft.(reduction of speed)
If the central gear number of teeth is Z
R, movable teeth rack radially guide groove number is Z
C, Z is then arranged
R=Z
C± 1.
If the high speed shaft rotating speed is n
1, the lower velocity shaft rotating speed is n
