摘要： A frictional transmission comprises first and second rotary shafts arranged in directions in which the central axes thereof crossed each other, a roller supported coaxially with the first rotary shaft for rotating with the first rotary shaft, a first frictional surface provided on the roller coaxially with the first rotary shaft, a disc supported coaxially with the second rotary shaft for rotating with the second rotary shaft, and a second frictional surface provided on this disc coaxially with the second rotary shaft. The second frictional surface and the first frictional surface are brought into frictional engagement with each other. A loading cam device is arranged so as to press the second frictional surface toward the first frictional surface at the time of driving. A further disc coaxial with the aforementioned disc is disposed in the environs of the second rotary shaft, and the roller is sandwiched by and between the two discs. This further disc is rotatably supported by an angular-type ball bearing relative to the second rotary shaft and the first-mentioned disc in the environs of the second rotary shaft in a state that this further disc is prevented from being displaced in a direction to be separated from the first-mentioned disc.

摘要： Under a state of a normal temperature, a pitch B2 of a feed nut 55, 65 is formed to be slightly larger than a pitch A2 of a feed shaft screw 53, 63. Accordingly, since the screw thread of the feed nut 55, 65 is pressed to the screw thread of the feed screw shaft 53, 63 with a small interference, there is no backlash between the feed screw shaft 53, 63 and the feed nut 55, 65 so that a smooth feeding operation can be carried out. Under a state of a low temperature, the feed nut 55, 65 contracts more than the feed screw shaft 53, 63. As a result, a pitch B1 of the feed nut 55, 65 has the substantially same dimension as that of a pitch A1 of the feed screw shaft 53, 63.
摘要翻译：在正常温度的状态下，进给螺母55,65的间距B2形成为稍大于进给轴螺杆53,63的间距A2。因此，由于进给螺母55,65的螺纹被挤压到进给丝杠轴53,63的螺纹，干涉小，进给螺杆轴53,63和进给螺母55,65之间没有间隙，从而可以进行平稳的进给操作。在低温状态下，进给螺母55,65比进给螺杆轴53,63收缩更多。因此，进给螺母55,65的间距B1具有与间距A1相同的尺寸的供给螺杆轴53,63。

摘要： Due to the meshing of the gears, the following force works on the rack. A separating force (Fα) determined by a pressure angle of gears, a lateral force (Fβ) determined by an angle of torsion of the rack, and drag (Fr) for offsetting angular moment occurring in the rack due to the lateral force (Fβ). A resultant (F) of the force works from the rack on the rack guide. When the line of this resultant (F) is held on the “inner side” of the end portions of the needle bearing 25 in this rolling type rack guide 21, the rotation of the roller 22 becomes stable.

摘要： A variable steering gear mechanism (9) is constructed of an external gear (15) connected to an input shaft (11), an internal gear (16) fixed to housing (10) and meshing with the external gear (15), an intermediate member (19) receiving a rotary force transmitted from the external gear (15), change means (18a, 31, 33a) capable of changing a rotation ratio of the output shaft (33) to a rotation of a guide member (18), and an Oldham coupling (17) connecting the intermediate member (19) to the guide member (18). When a speed reduction ratio thereof is set to, e.g., 6:1, it follows that the input member (18) of the change means makes a ¼ rotation (rotates through 90 degrees) during one-sided 1.5 rotations (540 degrees) of the input shaft (11), whereby a characteristic of the change means can be effectively utilized. A gear mechanism such as a hypocycloid mechanism has a characteristic capable of, though compact in configuration, obtaining a speed reduction ratio as large as 6:1, and also such a characteristic that the external gear (15), in addition to the self-rotation, revolves around the axis line of the internal gear (16), i.e., rotates while being eccentric. By contrast, according to the present invention, the use of the Oldham coupling (17) enables only the self-rotation to be extracted and transmitted by absorbing the eccentricity of the external gear (15). Additionally, a meshing length between the external gear (15) and the internal gear (16) becomes large, whereby smoother power transmission can be attained.
摘要翻译：可变转向齿轮机构（9）由连接到输入轴（11）的外齿轮（15），固定到壳体（10）并与外齿轮（15）啮合的内齿轮（16）构成，中间接收从外齿轮传递的旋转力的构件（19）;能够将输出轴（33）的旋转比改变为引导构件（18）的旋转的改变装置（18a，31,3aa））和将中间构件（19）连接到引导构件（18）的十字联轴器（17）。当其减速比设定为例如6:1时，改变装置的输入构件（18）在单向1.5转（540度）的1/4侧（540度）内进行1/4旋转（旋转90度）输入轴（11），从而可以有效地利用改变装置的特性。齿轮机构，例如下摆机构，其特征在于，虽然结构紧凑，但能够获得6:1以上的减速比，而且除了自转机外，外齿轮（15）旋转，围绕内齿轮（16）的轴线旋转，即，偏心旋转。相反，根据本发明，使用十字联轴器（17）仅能够通过吸收外齿轮（15）的偏心来提取和传递自旋。此外，外齿轮（15）和内齿轮（16）之间的啮合长度变大，能够实现更平滑的动力传递。

摘要： To provide an electrically driven power steering apparatus with a simple structure, which can prevent overloading of an electrical motor and a power transmission system, an absorbing member (121) is attached to a rack shaft (112), and is brought into contact with a rack housing face at a stroke end of the rack shaft (112). The absorbing member (121) at least partially has a material having a Young's modulus of 100 to 900 Mpa, and thus it is possible to effectively relieve an impact at the stroke end.
