МАШИНА ДЛЯ ИСПЫТАНИЯ РОЛИКОВ НА КОНТАКТНУЮMACHINE FOR TESTING ROLLERS FOR CONTACT

За влено 14 декабр  1959 г. за № 647355/25 в Комитет по делам илобротепим и открытий при Совете Министров СССРOn December 14, 1959, No. 647355/25 was filed with the Committee for Illobrotepim and Discoveries under the Council of Ministers of the USSR

Известны машины дл  испытани  роликов на контактную усталость, состо щие из станины, нередаточного механизма, привода и нажимното устройства. Однако на этих машинах обычно можно проводить испытани  роликов на контактную усталость только при совпадении векторов их окружных скоростей.Machines for testing roller contact fatigue are known, consisting of a bed, an elusive mechanism, an actuator, and a pushing device. However, on these machines it is usually possible to test the rollers for contact fatigue only when the vectors of their peripheral speeds coincide.

Предложенна  машина позвол ет нроводить испытани  в услови х несовпадени  по паправлению векторов окружных скоростей поверхностей роликов любого профил .The proposed machine makes it possible to carry out tests under conditions of mismatch in the direction of the vectors of peripheral speeds of the surfaces of the rollers of any profile.

На фиг. 1 схематически изображено взаимное расположение роликов на испытательной машине; на фиг. 2 - машина, вид сбоку; на фиг. 3 - то же, вид со стороны привода.FIG. 1 schematically shows the relative position of the rollers on the testing machine; in fig. 2 - car, side view; in fig. 3 - the same view from the drive side.

Принцип действи  машины заключаетс  в следуюшем. Испытуемые ролики располагаютс  на ос х, которые могут поворачиватьс  одна относительно другой на любой наперед заданный угол ср (фиг. 1).The principle of the machine is as follows. The test rollers are located on axles that can rotate one relative to the other by any predetermined angle cf (Fig. 1).

Ролики вращаютс  с угловыми скорост ми (oj и ы, соотношение их и абсолютна  величина каждой задаютс  по желанию экспериментатора. Векторы окружных линейных скоростей Kj и V2 на поверхност х роликов направлены перпендикул рно ос м вращени  колес.The rollers rotate with angular velocities (oj and y, their ratio and the absolute value of each are set at the discretion of the experimenter. The vectors of circumferential linear velocities Kj and V2 on the surfaces of the rollers are directed perpendicular to the axis of the wheels.

Вектор скорости скольжени  определ етс  векторным уравнением: V - 1/2. Величины скоростей Vi и V определ ютс  неличинамн угловых скоростей (i)i, (1)2 и радиусами роликов; величина же вектора скорости скольжени , кроме этого, зависит euie и от взаимного расположени  их осей вран1.ени .The slip velocity vector is determined by the vector equation: V - 1/2. The velocities Vi and V are determined by the non-indicative angular velocities (i) i, (1) 2 and the radii of the rollers; the magnitude of the slip velocity vector, moreover, depends on euie and on the relative position of their axes lie.

Направление и форма линии контакта определ етс  профил ми роликов и их взаимным расположением, что в совокупности с направлением скорости скольжени  определ ет угол а между направлением вектора скорости скольжени  и направлением линии контакта.The direction and shape of the line of contact is determined by the profiles of the rollers and their mutual arrangement, which, together with the direction of the slip speed, determines the angle a between the direction of the slip velocity vector and the direction of the contact line.

При имитации эвольвентного зацеплени  ролики имеют образующие , очерченные цилиндрическими, коническими или гиперболическими поверхност ми.When simulating involute engagement, the rollers have forming, contoured cylindrical, conical or hyperbolic surfaces.

При имитации зацеплени  НОВИКОЕЙ ролики должны иметь образующие в форме дуг окружностей, плоскости которых могут быть повериуты относительно осей вращени  роликов на любой угол.When imitating the engagement of the NEW, the rollers should have arcs in the form of arcs of circles whose planes can be verified with respect to the axes of rotation of the rollers at any angle.
