摘要： High-Efficiency gear Transmission of the present invention relates to the field of gear transmission technique, particularly to a high-efficiency double internal gear planetary transmission with small tooth number difference. High-Efficiency Gear Transmission of this invention provides with an entirely new double-ring gear and extra short toothed gears with changed gear parameters in order to obtain high transmission efficiency with reduced power loss in bearings and gear engagement. High-Efficiency Gear Transmission according to the invention comprises at least one double-ring gear composed of two integrated coaxial gear rings. Said double-ring gear having different tooth numbers on each ring is mounted on an eccentric shaft through planetary bearings. The double-ring gear performs planetary movement with two fixed-axle gears respectively. The vertical projections of the tooth widths of the two gear rings of said double-ring gear on their common axis at least partially coincide with each other. Both said gear rings are composed of either outer or inner gears. The distance between the projections of the center lines of their tooth widths in the direction of their common axis is zero. The distance b between the internal surface of the outer gear ring of said double-ring gear and the external surface of the fixed-axle gear engaged with the inner gear ring of said double ring gear must be not less than twice the eccentric distance a of the eccentric shaft. If the double ring gear and the fixed-axle gears engaged with it are all helical gears, the two internal helical gears are of the same hand, and so are the two external helical gears.
The high-efficiency gear transmission is provided with an extra short toothed gear pair with changed gear parameters. Its addendum coefficient h a is less than 0.5, the absolute value of its modified coefficient difference X is not more than 0.1, preferably equal to zero, and the modified coefficients of both extra toothed gears are preferably equal to zero. The two internal helical gears are of the same hand and so are the two external helical gears while said extra short toothed gear pairs are used for the two internal gear pairs of the double internal gear planetary transmission.
摘要翻译：本发明的高效率齿轮变速器涉及齿轮传动技术领域，特别涉及齿数差小的高效双内齿轮行星变速器。本发明的高效率齿轮传动装置提供了一种全新的双齿圈和具有变化的齿轮参数的超短齿轮，以便通过减少轴承和齿轮啮合中的功率损失来获得高传动效率。根据本发明的高效率齿轮传动装置包括由两个集成的同轴齿轮环组成的至少一个双重齿圈。在每个环上具有不同齿数的所述双齿圈通过行星轴承安装在偏心轴上。双环齿轮分别与两个固定轴齿轮执行行星运动。所述双重齿圈的两个齿圈在其共同轴上的齿宽的垂直突起至少部分地彼此重合。两个齿轮都由外齿轮或内齿轮构成。它们的齿宽在其公共轴线方向上的中心线的突起之间的距离为零。所述双重齿圈的外齿轮的内表面与与所述双重齿圈的内齿圈啮合的固定轴齿轮的外表面之间的距离b必须不小于所述双重齿圈的偏心距离a的两倍偏心轴。如果双环形齿轮和与其啮合的固定轴齿轮都是斜齿轮，则两个内螺旋齿轮是同一只手，两个外螺旋齿轮也是同一个。高效齿轮传动装置具有齿轮参数变化更小的齿轮齿轮。其齿顶系数ha小于0.5，其修正系数差X的绝对值不大于0.1，优选等于零，而两齿轮齿轮的修正系数最好等于零。两个内螺旋齿轮是相同的手，两个外部的斜齿轮也是如此，而所述的外部短齿轮对用于双内齿轮行星传动装置的两个内齿轮对。

摘要： A simplified design for a locking castor wheel, e.g. for a trolley, has the wheel mounting (22) attached to the covering cowl (20) by flexible struts. The inner moulding includes a support ring (25) for the steering brake. The castor brake comprises a pedal (100) mounted in a slot (24) in the cowl and operating on a brake band (30) under which is secured a brake lining (33) for the main wheel (60) and a brake profile (13, 32) to lock into a gear wheel (12) at the bottom of the steering shaft.

摘要： The roller fitment has a pair (1) of wheels (14) which are mounted spaced from one another to form an interspace in which an electrically conductive small roller (23) is mounted so that it can be pressed resiliently down. The small roller is made from an electrically conductive material and is mounted rotatable in a sheet metal U-shaped inner support (22) which is mounted vertically displaceable in the metal outer support (21) fixed in a holder (11). A compression spring (26) presses the inner support downwards.
