    • A low-temperature showcase comprises a heat insulated wall, on the top of which an opening for putting-into or taking-out commodities is formed. The inside of the heat insulated wall is divided into an air passage and a storage chamber thereover by a dividing plate which is installed inside this heat insulated wall in a nearly horizontal fashion. The air passage is formed in a manner that the cross-section thereof is of a U-shape, and the storage chamber is formed surrounded by this air passage. At both ends of the air passage, vent ports are formed at the positions facing each other through the opening of the heat insulated wall inbetween. The air passage is divided into two parts by a fan case corresponding to the respective vent ports and a blast fan which can rotate reversibly is supported by this fan case. In each halved air passage, an evaporator is installed in the vicinity of the vent port, and when one of the evaporators is put in cooling operation, the other evaporator is subjected to defrosting. An electric heater is installed between each vent port and each evaporator, and these electric heaters are energized when the corresponding evaporator is to be defrosted. By means of a thermo-switch, energizing of the electric heater is stopped when the air temperature in the air passage rises above a predetermined value during energizing the electric heater.
    • 低温展示柜包括隔热壁,顶部形成有用于投入或取出商品的开口。 绝热壁的内部由几乎水平的方式安装在该隔热壁内的分隔板分隔成空气通道和储存室。 空气通道以其横截面为U形的方式形成,并且储存室形成为被该空气通道包围。 在空气通道的两端,排气口形成在彼此相对的位置处,隔着隔热壁的开口。 空气通道由对应于各个通气口的风扇壳体分成两部分,并且由该风扇壳体支撑可逆地旋转的鼓风扇。 在每一个半空气通道中,蒸发器安装在通气口附近,当其中一个蒸发器进入制冷运行时,另一个蒸发器进行除霜。 在每个排气口和每个蒸发器之间安装一个电加热器,当相应的蒸发器要除霜时,这些电加热器通电。 通过热电开关,当在电加热器通电期间当空气通道中的空气温度升高到预定值以上时,电加热器的通电停止。

    • A sun gear 6 is concentrically, rotatably disposed inside an internal gear 4. Plural planet gears 8, carried by a planetary carrier 10, are disposed between and in meshing engagement with the internal gear 4 and the sun gear 6. The planetary carrier 10 is connected to a shaft extending from an engine while the internal gear 4 and the sun gear 6 are connected to output shafts. The internal gear 4 is molded by a plastic working, followed by a thermal treatment including soft-nitriding, a nitriding and a carburizing hardening step. The inner surface of the internal gear 4 is formed with internal gear teeth 4b, except for an axial portion 4d, while a spline groove 4a is formed on the outer surface of the internal gear 4 at a location corresponding to the portion 4d where no internal teeth 4b are formed for engagement with a spline 2a on a housing 2. The internal gear 4 is reduced in size while improving the mechanical strength thereof.
    • 太阳齿轮6同心地可旋转地设置在内齿轮4的内部。由行星架10承载的多个行星齿轮8设置在内齿轮4和太阳齿轮6之间并与内齿轮4和太阳轮6啮合。行星架10 连接到从发动机延伸的轴,而内齿轮4和太阳齿轮6连接到输出轴。 内齿轮4通过塑性加工成型,然后进行包括软氮化,氮化和渗碳硬化步骤的热处理。 内齿轮4的内表面形成有内齿轮齿4b,除了轴向部分4d之外,而在内齿轮4的外表面上形成花键槽4a的位置对应于部分4 d,其中没有内齿形成用于与壳体2上的花键2a接合。内齿轮4的尺寸减小,同时提高其机械强度。
