| 内容記述 | It is generally known that rolling friction is much smaller than sliding friction. However slight the friction of rolling bearings may be, when such bearings are applied in industrial instruments, the properties in the instruments are important factors in their accuracy, sensibility and performance. This experiment has been made in order to investigate the kinetic fricfional moment of a rolling steel ball, to record the movement of the ball along a horizontal V rail from slowmotion to standstill on the film. Experiments contributed to obtain the mechanism for friction in bearings. The effects of various materials used in the rails, i. e., the elasticity and hardness of the materials and the effect of lubrication have been investigated. Experimental results are roughly summarized as follows : 1) When the contact pressure between the ball and the rail are within a elastic limit, the frictions are mainly in fluenced by the Young's Modulus, but when out of its elastic limit, the frictions are mainly effected by the Shore's hard ness. 2) Oil will surely increase the frictional moment. 3) Friction is created, to a large extent, by deformation between contact sur faces caused by pressure. 4) In general, frictional moments gradually increase with retardational motion till at last maxe. value of friction is reached uniquely. The more the friction is, the more distinct is this tendency. 5) As the amount of rolling friction is small, the factors of the friction come to be numerous, and so the reproducibility of experiments are more difficult than those of sliding experiments. | |||||||
