Abstract
The utility model discloses a self-regulating gear which comprises an external tooth ring, wherein the external tooth ring is fixed to a sleeve barrel with an internal spherical surface via bolts; the internal spherical surface of the sleeve barrel is provided with a guiding groove; a bearing sleeve with an external spherical surface is arranged in the sleeve barrel; the external spherical surface of the bearing sleeve is attached to the internal spherical surface of the sleeve barrel; a cylindrical pin is fixed on the external spherical surface of the bearing sleeve; the cylindrical pin is inserted in the guiding groove; the sleeve barrel is formed by the method that an upper half sleeve barrel with a groove is combined with a lower half sleeve barrel with a lug boss. The utility model has the advantages that the installation error of a transmission shaft can be corrected automatically, the normal running of a transmission system is ensured, the service life of a transmission gear is prolonged, the structure is simple, etc.
Description
Technical field:
The utility model relates to a kind of driving gear wheel, particularly a kind of can self-regulating driving gear.
Background technique:
Present train transmission mostly is ordinary transmission greatly, because formed error when manufacturing, installation, as the parallelism of two transmission shafts when mounted, deviation of concentricity etc., usually make that transmission system breaks down, not only influence the quality of transmission, and influenced the intensity and the working life of driving gear.As: to two sprocket driving, require the angle between its two plane of rotation must be not more than 0.006rad,, just may cause and take off chain if greater than this value.And to synchronizing jugged belt wheel transmission, the parallelism of its two belt wheels axis must be not more than 0.10 ~ 0.15mm/100mm and measure length, if greater than this value, then synchronous cog belt comes off probably.
Summary of the invention:
The purpose of this utility model is: provide a kind of energy self-regulating gear, to avoid causing transmission system to break down because of the error that transmission shaft forms when making and install, to overcome above-mentioned the deficiencies in the prior art.
The utility model is to constitute like this: it comprises external toothing, external toothing is by being bolted on the sleeve that has inner ball surface, on the inner ball surface of sleeve, be provided with guiding groove, and the bearing housing that has outer spherical surface is housed in sleeve, the outer spherical surface of bearing housing and the inner ball surface of sleeve are fitted, on the outer spherical surface of bearing housing, be fixed with straight pin, and straight pin is inserted in the guiding groove; Sleeve is by first sleeve that has groove and involutory composition of second sleeve that has boss.
Owing to adopted technique scheme, external toothing is fixed on the sleeve, and the sleeve of inner ball surface links to each other with the bearing housing of outer spherical surface by straight pin and relatively moves, external toothing just can be with respect to relative the moving of bearing interplanting like this, when transmission when there is error in two parallel transmission shafts, driving gear can be by regulating its position with relatively moving of bearing housing automatically, thereby correct the adverse effect of bringing owing to the alignment error of transmission shaft, ensure the normal operation of transmission system, but also can prolong the working life of gear.So the utility model compared with prior art, and the alignment error that it has energy automatic straightening transmission shaft ensures the normal operation of transmission system, the working life and the advantage of simple structure that can prolong driving gear.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the A-A sectional view of accompanying drawing 1.
Embodiment:
Embodiment of the present utility model: as shown in Figure 1, on the outer spherical surface of the bearing housing 4 that has outer spherical surface, open the counterbore of dress straight pin 5, and in counterbore, load onto straight pin 5; On the inner ball surface of the sleeve 3 that has inner ball surface, offer guiding groove 6 then, first sleeve that has groove 7 with sleeve 3 during installation is enclosed within earlier on the bearing housing 4, and straight pin 5 is contained in the guiding groove 6, make straight pin 5 in guiding groove 6, to slide, second jacket casing that will have boss 8 then is on bearing housing 4, and with the groove 7 of first sleeve and boss 8 involutory the linking together of second sleeve, make the outer spherical surface of bearing housing 4 and the inner ball surface of sleeve 3 fit together, at last with external toothing 1 usefulness bolt 2 and packing ring, nut is fixed on first sleeve of sleeve 3 and second sleeve and gets final product.
Claims (2)
