Изобретение относитс  к области машиностроени  и используетс , в основном, в цементной п химической промышленности.The invention relates to the field of mechanical engineering and is used mainly in the cement and chemical industries.

Известна звездочка, имеюща  несимметричный криволинейный нрофиль зубьев с пр молинейными рабочей и нерабочей поверхност ми 1.An asterisk is known, having asymmetrical curvilinear teeth profile with straight working and non-working surfaces 1.

Недостаток такой звездочки заключаетс  в том, что угол заострени  зуба одинаков с обеих сторон, вследствие этого звездочка не может обеснечить нормальное зацепление с цеп ми , имеющими, кроме скругленных элементов зацеплени , рабочие профили специальной формы.The disadvantage of such an asterisk is that the tapering angle of the tooth is the same on both sides, as a result of which the asterisk cannot neutralize normal engagement with chains that have, in addition to rounded hooking elements, special shaped working profiles.

Цель изобретени  - повысить надежность и долговечность работы звездочки, а также обеспечить возможность работы ее при повышенных температурах.The purpose of the invention is to improve the reliability and durability of the sprocket, as well as to ensure the possibility of its operation at elevated temperatures.

Это достигаетс  тем, что впадины между зубь ми выполнены под углом а к касательной окружности впадин, а рабочие поверхности зубьев сопр жены с поверхност ми впадин под углом р, при этом угол , а угол .This is achieved by the fact that the depressions between the teeth are made at an angle a to the tangential circumference of the depressions, and the working surfaces of the teeth are mated to the surfaces of the depressions at an angle p, the angle, and the angle.

Иа чертеже схематически показана предлагаема  звездочка, общий вид.Fig. 1 shows schematically the proposed asterisk, general view.

Звездочка 1 имеет несимметричный криволинейный профиль зубьев 2. Поверхность впадины 3 между зубь ми 2 выполнена пр моли2The asterisk 1 has an asymmetrical curvilinear profile of the teeth 2. The surface of the depression 3 between the teeth 2 is made straight.

нейной под углом а к касательной окружности в пределах , а угол (3 сопр жени  рабочей поверхности 4 зуба 2 с поверхностью впадины 3 выполнен в пределах . Предложенна  звездочка повышает надежность , долговечность и экономичность работы в цепи, а, следовательно, конвейера или цепной передачи в целом.angle at the tangential circle within, and the angle (3 matings of the working surface 4 of the tooth 2 with the surface of the trough 3) is made within. The proposed asterisk increases the reliability, durability and efficiency of work in the chain, and, therefore, of the conveyor or chain drive in whole
